Technical Field

The invention belongs to the technical field of textile processing, and particularly relates to a silk quilt capable of being exposed and a preparation method thereof.

Background

The silk is different from cotton and wool, is not originated from cells, but is formed by secreting liquid silk protein by the cells and then spitting out the liquid silk protein by silkworms, so that the silk has the characteristics which are quite different from other natural fibers, contains more than 97 percent of animal protein and 18 amino acids necessary for human bodies, is the natural animal protein fiber closest to the skin of the human bodies at present, has the similar proximity of up to 87 percent, has the reputation of 'second skin of the human bodies', 'fiber queen' and the like, has the characteristics of healthy fiber, is natural healthy fiber, has wide application and good application and development prospect, and is widely applied to the industries of medical treatment, cosmetology, clothing, home textiles and the like at present.

The silk is a natural fiber, and is easy to age due to the comprehensive action of various environmental factors in the storage and use processes, wherein the influence of photoaging, thermal aging and hydrolytic (wet) aging on the silk is the largest. The silk quilt is a main product taking silk as a raw material in the home textile industry, is soft, comfortable, skin-friendly, close-fitting, breathable, warm-keeping, green and healthy, is deeply favored by consumers, but the characteristics of silk fiber can have certain contradiction with the use and maintenance scenes of the quilt, and the focus of the contradiction is mainly focused on the use comfort, health and service life of the silk quilt.

Wherein the aging of silk comprises three of hydrolytic (wet) aging of silk, photoaging of silk and thermal aging of silk:

hydrolysis (wet) ageing of silk: the main components of silk are fibroin (i.e., silk fibroin) and sericin (i.e., sericin), which are both proteins, but have different properties due to different compositions and structures of amino acids. When silk fibroin and sericin contact with a liquid such as moisture, the liquid such as moisture is automatically absorbed to swell and soften, and this process is called swelling (swelling). Although both silk fibroin and sericin can swell by absorbing water, their final results are different because the swelling is divided into infinite swelling and finite swelling. After the sericin absorbs the water, the sericin continuously and gradually swells in the water, and the swelling is continuous and infinite, so the sericin is dissolved in the water. On the contrary, the swelling of silk fibroin in water is limited, so that silk fibroin is insoluble in water. Of course, the wireless swelling and the limited swelling are not absolute and may vary depending on the conditions. Example (b)For example, sericin swells in cold water to a limited extent and swells in hot water to a non-linear extent and dissolves. Fibroin generally swells in water to a limited extent, but when a specific salt is dissolved in water, it can also swell and dissolve without a wire. In addition, the silk fiber has many polar groups in its large and small molecules, such as-OH (hydroxyl), -COOH (carboxyl), -NH₂(amino), -CONH (amide), etc., which are hydrophilic groups having a certain affinity for water molecules; the silk is a composite protein, which not only has a good special-shaped cross section structure, but also has a crystalline region and an amorphous region with proper proportion determined by the amino acid composition and the high-order structure of protein molecules, so that the fiber structure of the silk can present an irregular 'crystal' and 'pore' state, so that the fiber has a plurality of small pores (namely, porosity) inside, and the silk has the capacity of absorbing water in the air. The moisture absorption property is that when the air humidity is in a saturated state, the moisture absorption expansion of the silk can reach about 30 percent; in conclusion, due to the specific composition and structure of the silk fiber, the silk fiber has good moisture absorption performance. When it absorbs moisture, its physical properties, chemical properties and processing properties are changed to some extent. The phenomenon of fiber hardening is reflected on the silk quilt, and the phenomenon of fiber hardening can cause the reduction of filling power, the reduction of air permeability and heat retention, the reduction of use comfort, the easy breeding of bacteria, the acceleration of hydrolysis (wet) aging of silk and the like. The only way to solve these problems is to: the silk fiber deodorant is capable of quickly and efficiently removing water absorbed in the silk fiber, keeping the silk fiber dry, and simultaneously performing effective sterilization and deodorization treatment. The most direct, most convenient, most economical, most effective and most natural means for realizing the method is to directly expose the silk quilt under the sun, namely, the characteristics of sunlight are fully utilized to realize the functions of dehumidification, moisture prevention, disinfection and sterilization and peculiar smell removal.

Photo-aging of silk: the main components of sunlight are: visible light, infrared and ultraviolet. With the continuous development of modern industry, the atmospheric pollution is getting more and more serious, so that the thickness of an ozone layer is getting less and the ozone layer cavity is getting more and more serious, ultraviolet rays (UVA/UVB/UVC) reaching the ground are also increasing, and the problem of ultraviolet radiation is getting more and more prominent; the Ultraviolet (UV) can be divided into three sections according to wavelength, long-wave ultraviolet (UV-A, 320-400 nm), medium-wave ultraviolet (UV-B, 280-320 nm) and short-wave ultraviolet (UV-C, 200-280 nm). In addition, the ultraviolet radiation is 10-200 nm far ultraviolet radiation, or vacuum ultraviolet radiation. The ultraviolet ray is a double-edged sword, and proper ultraviolet rays are beneficial to human bodies, such as disinfection, sterilization, promotion of synthesis of vitamin D of the human bodies and the like; however, excessive UV light can cause adverse effects on the human body, such as loss of muscle tone, roughness of the skin, wrinkles, skin cancer, and the like. The silk is natural animal protein fiber, the proximity of the main components of the silk to human skin is up to 87%, and the light resistance of the silk is poor, so that the influence of ultraviolet rays on the silk is very obvious and the effect is mainly reflected on light aging; the strength and the elongation of the silk under the irradiation of ultraviolet rays are inversely proportional to the illumination time (namely, the strength and the elongation are reduced more as the irradiation time is longer), so that the aging speed of the silk under the ultraviolet rays is intuitively reflected to be rapid. Therefore, the method for relieving the photo-aging can adopt the method of avoiding the irradiation of ultraviolet rays or absorbing and filtering the ultraviolet rays so as to reduce or avoid the photo-aging problem of the silk.

Thermal aging of silk: the silk fibre is under hot effect, along with temperature gradual rise, the vibration kinetic energy of the inside macromolecule of fibre can increase gradually, and intermolecular interaction reduces, can take place the decomposition of macromolecule finally, and the temperature when macromolecule decomposes is called the decomposition point, and the decomposition point of silk fibre is about 150 ℃. Regarding the thermal stability (i.e. heat aging) of silk, it is well known that silk is heat-aged, but the heat aging of silk is not significant during normal use because normal use scenarios do not reach very high temperatures. So that no very specific measures or measures need to be taken in dealing with thermal ageing.

Obviously, in order to solve the problem of aging of the silk quilt, the silk quilt is ensured to be dry so as to avoid hydrolytic (wet) aging of the silk, and the silk quilt is ensured to have excellent sun-proof performance so as to avoid photoaging of the silk; in the prior art, various treatment methods are provided for improving the sun-screening performance of silk products to achieve the sun-screening effect, such as:

for example, chinese patent CN201810538984.7 discloses a sun-protective garment, which comprises a sun-protective garment body, wherein the sun-protective garment body is formed by mixing and spinning silk fibers and pearl fibers, ceramic micro powder is embedded in the silk fibers, and a first cavity for air circulation is formed in the pearl fibers, wherein the silk fibers have a soft and breathable effect, the pearl fibers have the effects of beautifying and skin protection, and have the characteristics of moisture absorption, ventilation and comfort in wearing;

for example, chinese patent CN201910055822.2 discloses a sun-proof and wear-resistant treatment technology for real silk, which comprises the following steps: killing silkworm pupae by utilizing hot air or electromagnetic waves and the like, removing a proper amount of water, and strengthening temperature and humidity control and taking protective measures during silkworm cocoon storage; step two: reeling silk, namely spraying the silk-splitting degreasing solution on the dried silkworm cocoons in the step one while silk-splitting, and preparing the silk cocoons into sheet silk with degreased sericin still adhered to the silk by a silk-drawing machine; step three: soaking, namely, the sun-proof and wear-resistant treatment technology for manufacturing real silk, and the silk-splitting degreasing solution is prepared by mixing 92-98% by mass of degreasing enzyme and water in a weight ratio of 1: 150-1: 400, the deallipase is used, so that the damage of the alkaline liquid to the natural elasticity and the wear resistance of the silk is avoided, the natural performance of the silk can be maintained, and the problem that the surface sun-proof performance of the cicada silk is reduced due to the damage of chemical agents to the surface fibers of the cicada silk in the prior art is solved;

obviously, although the prior art also has the technology of sun-screening silk products, most of the prior arts adopt the sun-screening treatment of silk fibers formed by mixing and spinning silk fibers and other types of fibers, and do not relate to the sun-screening treatment for improving the ultraviolet resistance of pure silk fibers and the sun-screening treatment of silk quilts.

The silk quilt capable of being exposed is reasonably designed from the aspects of product process structure and professional preparation technology, not only can the purposes of exposing and improving the using effect of the silk quilt be achieved, but also the thin summer quilt can achieve a certain degree of whole quilt water washing.

padding with an ultraviolet-proof solution (the rolling residual rate is 70-80%) → drying (90-120 ℃ for X120 min).

The process method comprises the following steps:

the preparation of the silk floss flocculus comprises the following steps: beating cotton → degumming → refining → washing → dehydration → finishing → dehydration → drying → natural cooling and recovering the processes. When the ultraviolet-proof process treatment is carried out, mainly from the finishing step, the operation steps are two types:

finishing → dehydrating → anti-ultraviolet processing → dehydrating → drying → natural cooling and recovering.

Finishing, carrying out the co-bath treatment of the ultraviolet-proof process → dehydrating → drying → natural cooling and recovering.

Through repeated test comparison, the two operation steps can realize the ultraviolet-proof function, wherein the second step mode is more convenient, efficient, economic and environment-friendly in actual operation, so that a proper process formula and a proper process flow are designed in a co-bath treatment link aiming at the second mode, and the method specifically comprises the following steps:

the process formula comprises the following steps:

glacial acetic acid 0.6-0.8% (w.o.f), softener (amino silicone oil) 2.5-3.5% (w.o.f), ultraviolet-proof finishing agent HTUV 10030-50 g/L, and cross-linking agent AF 670030-50 g/L.

The process flow comprises the following steps:

adding the auxiliary agents (glacial acetic acid → softener → ultraviolet-proof finishing agent → cross-linking agent) in sequence, stirring → putting in the cleaned and dehydrated silk floss flakes → dehydrating (the residual rate is 70-80%) → drying (90-110 ℃ X120 min).

When the silk ultraviolet-proof process is specifically realized, a common padding method or a vacuum infiltration method can be selected, and the advantages and the disadvantages of the two methods and the specific operation are as follows in the following table 4:

table 4:

and (3) detecting the ultraviolet resistance:

the detection is carried out by adopting GB/T18830-2009, and the specificity of the material and the property of the silk is considered, so that the detection needs to be carried out after professional treatment. And before the qualified third-party detection mechanism is formally sent for detection, self-detection is firstly carried out:

the self-test principle is as follows: absorb ultraviolet rays.

Self-test tool: an ultraviolet detection lamp.

Self-test materials: the silk which is not processed by the ultraviolet-proof process, and the silk which is processed by the ultraviolet-proof process.

The self-testing method comprises the following steps: an irradiation contrast experiment was performed.

The self-test comparative experiment was as follows:

fig. 1 is a graph, which is to arrange silk (fig. 1, left side) that is not treated by anti-ultraviolet process and silk (fig. 1, right side) that is treated by anti-ultraviolet process together, and compare under the irradiation of same light source, silk luminance on the left side is obviously higher than silk on the right side, and it proves that silk on the right side can effectively absorb ultraviolet rays after being treated by anti-ultraviolet process, silk on the left side in fig. 1 is not treated by anti-ultraviolet process, and silk on the right side is treated by anti-ultraviolet process.

Fig. 2 is a contrast solid graph of the effect that the light appears on silk with the extrusion of ultraviolet ray detection lamp, and through picture we can find easily that the extensibility of the light of silk that does not pass through anti-ultraviolet ray processing is stronger, and the extensibility of the light of silk that passes through anti-ultraviolet ray processing is obvious poor, shows that the silk that passes through anti-ultraviolet ray processing can effectual absorption ultraviolet ray, and the silk on the left in fig. 2 passes through anti-ultraviolet ray processing, and the silk on the right does not pass through anti-ultraviolet ray processing.

FIG. 3 is a graph showing the effect of the ultraviolet ray detection lamp on the light beam near silk (keeping a distance of 2-4 cm). Because the irradiation distance is kept, the visual effect that the picture appears has obviously been promoted and enlarged on light brightness and scope to figure 2, but no matter contrast about figure 3, still compare with figure 2, the silk that passes through anti ultraviolet technology and handles has good performance under the irradiation of ultraviolet ray detection lamp, can very effectual absorption ultraviolet ray, the silk on the left in figure 3 is through anti ultraviolet processing, the silk on the right does not have anti ultraviolet processing.

And after the design development and the self-test of the new product are finished, carrying out third-party detection for verifying the real effect of the product. The test results are shown in the following table 5:

4. product process structure adjustment optimization

The problem that the silk quilt can be directly insolate for a long time under the sun has been solved from the source at the technical level, but for the life of better promotion silk quilt, use experience effect such as sense, need adjust the optimization in the aspect of production technology, the structure of product.

1. Adjusting and optimizing the process:

the original optimization improvement of the drawing process of the silk floss blank is changed from the original optimization of 'pine floss → weigh floss → cut floss → draw floss → lay floss → edge closing' into the optimization of 'pine floss → weigh floss → pine floss → cut floss → draw floss → alternate lay floss → edge closing'. Including but not limited to silk grade under the same condition, silk weight, drawing size etc, technology after the optimization can be loosened silk extremely and is felt, increase the hole between silk and the silk, increase the number of piles of drawing, let the silk mechanism more clear, the exhibition, the effect is level and smooth, moreover, the steam generator is stable in structure, make the silk child possess splendid fluffy effect, use experience such as ventilative, keep warm, gentle, comfortable has been promoted, can ensure that the later stage finished product obtains good recovery effect at the in-process that uses the sunning above all, let the silk quilt use more permanent, more comfortable, healthier.

In the aspect of the silk quilt finished product manufacturing process, the original method that the bare silk quilt is directly turned into the outer-layer quilt cover and fixed (the fixing mode includes but is not limited to pure manual fixing, machine fixing and the like) is adopted, the inner lining layer (the mode includes whole set, layered cotton clamping and the like) is improved and added to wrap and fix the bare silk quilt, and then the bare silk quilt and the outer-layer quilt cover are turned and sewn fixedly.

2. And (3) adjusting and optimizing the structure:

and adding an inner liner layer.

The material of the inner liner layer:

including but not limited to cloth, gauze, non-woven fabric, and the like. The material includes but is not limited to cotton, polyester, regenerated, blended, etc.

Size of the inner liner layer:

according to national standards and relevant regulations, the size of the silk quilt finished product meets relevant requirements, so that the silk quilt size deviation is ensured within a standard range by performing necessary size pre-arrangement on the cutting size of the quilt wadding according to the filling amount. The cutting size of the common product cutting piece is within a preset range: + 5-10 cm, this product combines actual subsequent production technology, need carry out additional size on the basis of + 5-10 cm again, and its preliminary range: + 6-10 cm.

And (3) lining layer structure process:

realizing 'integral nested' or 'layered foam clamping' according to actual requirements. The integral sleeve type is that four sides of two layers of lining materials are sewed, and only one opening of a conventional turned wire tire is reserved (as shown in figure 4). The layered cotton sandwiching type is to directly lay the two layers of lining materials without sewing (as shown in fig. 5) when making the product. After the silk tires are duplicated, basic fixing of manual sewing needles is firstly carried out on four sides of the silk tires, then the four sides of the silk tires are matched with the outer-layer quilt tire covers, and point taking fixing of the four sides and the quilt surface is carried out, wherein the point taking fixing includes but is not limited to manual sewing needle fixing, sewing machine fixing, quilting machine quilting fixing and the like.

3. Optimizing the outer-layer quilt wadding sleeve.

The outer layer quilt wadding cover material:

including but not limited to cotton, polyester, recycled, blended, etc.

Size of the outer quilt wadding sleeve:

the cutting size of the common product cutting piece is within a preset range: + 5-10 cm, this product combines actual subsequent production technology, need carry out additional size on the basis of + 5-10 cm again, and its preliminary range: + 4-8 cm.

The outer layer quilt cover structure process comprises the following steps:

firstly, edges are reserved according to 2cm when the quilt cover is sewn, namely the distance from the edges of the cut pieces to the sewing lines is kept to be 2cm, and the needle pitch is required to be 12-15 needles/3 cm. And secondly, reserving a cotton turning opening with the length of about 50cm, wherein the cotton turning opening can be a pure cotton turning opening or a checking opening. And thirdly, manually fixing four edges of the silk padding (including the lining) and the outer-layer quilt padding cover, and then, sewing the four edges by using a sewing machine worker for thread-arranging and seam-fixing. Finally, adjustment is carried out on the aspect of fixing finished products according to the actual conditions of thickness, application season and the like of the silk quilt, after four sides of the summer quilt (the gram weight is less than or equal to 500g) are fixedly sewn, the quilting pattern is not limited, but small flower positions or points are suggested for quilting so as to reduce the influence of the quilting pattern on the filling power, the water-washable effect can be achieved to a certain degree, and the spring and autumn quilt and the winter quilt are subjected to manual needle hanging. The whole structure process is shown in fig. 6.

In summary, the preferred embodiments of the present invention are shown and described, and some modifications of the embodiments that may occur to those skilled in the art will embody the principles of the present invention and shall fall within the technical scope of the present invention.
