The invention relates to the technical field of underwear manufacturing, in particular to underwear cups and a manufacturing method thereof.
[ background of the invention ]
Bras, the women's underwear, as the daily indispensable dress of contemporary women, it has decorative and functional concurrently. Decorative needless to say, the most important embodiment of its functionality is exactly to the bearing of chest with gather together the effect, only a simple cloth can't play good bearing and gather together the effect, so the cup of brassiere must be provided with the supporter (cup inside lining or cup intermediate layer promptly), plays good bearing and gathers together the effect through the supporter. The support that previous brassiere cup chooseed for use is sponge material basically, however, along with the development of society and people to the improvement of healthy cognition, people know the sponge gas permeability poor gradually, breed the bacterium easily, have shortcoming such as volatility and can influence the health of women's chest. Some inferior sponges have great toxicity, which can easily cause female breast diseases and even cancers.
Therefore, in recent years, the industry has been searching for other alternative materials, in which upright cotton (a general term for synthetic fibers or plant fibers) as a novel underwear material with strong air permeability and capable of replacing sponge is also gradually applied and popularized in a large scale. The upright cotton is taken as a fiber material, and the specific filamentous fiber structure of the upright cotton endows the underwear cups with good air permeability, but the fiber structure also makes the material difficult to shape, the underwear cups are easy to shift and loosen after being kneaded, particularly washed by water, so that the underwear cups deform, the surface cloth wrinkles on light people, the underwear cups collapse on heavy people and the like. The prior art has a technical solution to solve the problem of collapse of the latter, such as chinese patent "upright cotton breathable bra cup pad with silica gel net and method for making the same", publication No. CN105935158A, publication No. 2016.09.14, which adopts the structure of upright cotton interlayer, adhesive layer and adhesive net layer to fix the fiber material, chinese patent "a silicon silk cotton product and method for making the same", publication No. CN 105696352B, publication No. 2018.04.10, which adopts silica gel composite fiber to fix the fiber material. Thus, although the problem is solved by serious users, the problem is still troubled by a plurality of practitioners, and the wrinkle phenomenon is generally difficult to be accepted by the brand underwear market, especially by the end female consumers who pursue perfection, so that the 'light user' problem is not light.
In view of the above problem, there is also a solution at present, that is, a sandwich fabric with a thickness of more than 1.2mm is selected to be adhered to a fiber material (in the prior art, a common fabric is adhered to the fiber material), because of the special multi-layer structure and thickness of the sandwich fabric, even if the sandwich fabric is deformed by washing, only the adhesion layer of the sandwich fabric and the inner side of the mesh are deformed, but the outer surface layer of the sandwich fabric is not deformed basically. However, the sandwich fabric is expensive due to the complex production process, and the sandwich fabric is limited in application and popularization due to the fact that the sandwich fabric cannot be randomly dyed, cut and spliced like a common fabric, and is not suitable for the popular and diversified consumer market. In addition, another solution is provided, common cloth is still selected, only the sponge is attached to the common cloth, and the sponge is adhered to the fiber material to form a multi-layer structure.
Therefore, the invention is produced.

[ detailed description ] embodiments
For the understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.
As shown in fig. 1 and 2, the underwear cup according to the present invention is sequentially provided with a first fabric layer 1, a fiber composite layer 2 and a second fabric layer 3 from outside to inside, the first fabric layer 1 and the fiber composite layer 2, and the second fabric layer 3 and the fiber composite layer 2 are bonded by elastic glue, the fiber composite layer 2 is an integral structure formed by combining elastic glue and fiber material, the fiber composite layer 2 is divided into a
Specifically, the density of the selected fiber material in the fiber composite layer is less than or equal to 16kg/m3It can be ordinary fiber or processed fiber, such as silicon silk floss prepared by Chinese patent 'a silicon silk floss product and its preparation method', publication No. CN 105696352B, publication No. 2018.04.10. The elastic rubber used in the invention is mainly silicon rubber, in particular addition type vulcanized silicon rubber, namely a blend of vinyl silicone oil, a reinforcing material, hydrogen-containing silicone oil and platinum, and the addition type liquid silicon rubber can be diluted by a solvent or emulsified by water to reach the operation viscosity.
When the common fibers are adopted, the
The fiber composite layer 2 is formed with a grid structure with elastic glue and fiber adhesion at the
The
In order to ensure the stability of the adhesive attaching area forming a grid structure for adhering elastic adhesive and fibers and to ensure that the fabric is not easy to wrinkle, the adhesive attaching area is a high adhesive attaching area (the high adhesive attaching area is an area with the content of elastic adhesive being significantly more than that of other adhesive attaching areas, which is explained in detail in the specific embodiment) close to the surface layer of the fiber composite layer, the thickness of the high adhesive attaching area is at least 1.5mm, and the mass of the elastic adhesive in the high adhesive attaching area is at least 1.5 times that of the mass of the fiber material. Because the fiber material is a light material and has small space density, the loose fibers can be adhered and locked only by the elastic glue with enough quantity under the action of the rope, and the grid structure of the loose fibers cannot be easily damaged by external force. In addition, a low viscosity liquid elastic adhesive that is flowable and easily adheres may be selected so as not to block the fiber lattice structure and affect the breathability of the bra cup.
The elastic glue content of each pair of bra cups is 6-35 g, namely the glue content of each pair of bra cups is 6-35 g, and further, the elastic glue content of each pair of bra cups is 8-25 g. The content can ensure that the adhesive attaching area, especially the high adhesive attaching area of the bra cup of the invention forms a stable grid structure, so that the surface layer of the fiber composite layer is not easy to be damaged by displacement and dragging of the inner layer fiber to cause wrinkling of the fabric layer. Specifically, the elastic glue content of different underwear cup models is different according to the surface area of the cup, and the elastic glue content of D cup or E cup can reach 35 g because the cup shape is large and the surface area is large, and correspondingly, the elastic glue content of A cup or B cup is less because the cup shape is small and the surface area is small.
The fiber composite layer 2 forms a spongy grid structure at the high adhesive-adhering region with the thickness of more than 1.5mm, namely, the sponge-like grid structure plays a role similar to sponge, and for the elastic adhesive composite fiber, 1.5mm can ensure that the grid structure cannot deform due to the fact that the composite fiber at the high adhesive-adhering region is loosened due to displacement and pulling of the inner layer fiber during washing. The spongy grid structure not only has stable structure and good elasticity, but also has light texture, can prevent the fabric layer attached to the spongy grid structure from wrinkling, and ensures that the underwear cup disclosed by the invention is comfortable to wear and has better touch feeling.
Furthermore, when the thickness of the high adhesive-adhering area is between 3mm and 5mm, the whole fiber structure of the fiber composite layer at the high adhesive-adhering area is very stable, even if the inner-layer fiber structure is washed and displaced, the surface-layer fiber structure cannot be pulled, and the crease-resisting effect can be achieved. More importantly, considering the cost of glue, 3-5 mm is the perfect combination of quality and cost, and is the optimal choice of the invention, certainly the crease-resistant effect of the high glue-attaching area with the thickness of more than 5mm is also good, and the cost of glue is high, the whole weight of the cup can be increased, and the cup does not meet the industrial requirement of light weight, so that the wearing comfort is reduced.
The fiber composite layer 2 is of an integral fiber structure. Specifically, the so-called integral fiber structure, i.e. the fiber composite layer, is formed by adhering elastic glue to the whole fiber material as the matrix, rather than the multi-layer material as described in the background art. Such a unitary structure has many benefits, such as breathability, manufacturing process, cost, efficiency, cup texture, wear, etc., over a multi-layer structure, and such a design is perceived in the industry as qualitative rather than quantitative.
The first fabric layer 1 and/or the second fabric layer 3 are fabrics with the thickness of less than 1mm, the fabrics with the thickness of less than 1mm can better embody the texture of the cup, and the material cost can be reduced.
The first fabric layer 1 and/or the second fabric layer 3 are complete fabrics or spliced fabrics, the complete fabrics, namely the fabric layers, are made of one fabric, and the spliced fabrics, namely the fabric layers, are spliced or sewn by a plurality of fabrics. The fabric layer is a fabric, and specifically can be cotton cloth, linen cloth, non-woven fabric, lycra fabric, mesh fabric, nylon cloth, modal fabric or chiffon fabric. The invention not only greatly reduces the cost and has considerable profit by adopting the common cloth to replace the sandwich cloth, but also overcomes the problems that the sandwich cloth is not easy to color, is difficult to cut and splice and the like because the common cloth is simple to splice, is easy to dye and the like.
The surface of the first fabric layer 1 or the second fabric layer 3 is also printed with a functional coating, and specifically, the functional coating can be a nano negative ion layer, a nano silver layer, a chitin layer, a magnetic nano material layer, a graphene layer and the like. And printing different functional coatings on the surface layer of the fabric according to different requirements. Since the underwear cup of the present invention is not easily wrinkled, the coating layers can be well protected from being damaged by washing so that the coating function can be more realized.
The invention relates to a method for manufacturing underwear cups, which comprises the following steps:
A. manufacturing a cup substrate: die cutting the fibrous material into a cup matrix in the shape of a cup;
B. selecting or preparing a liquid elastic glue: selecting a liquid elastic adhesive with the pure viscosity or the operational viscosity of 250000mPa & s or less after being diluted by a solvent;
C. imprinting the liquid elastic glue: compressing the cup substrate to below half of the original thickness through a silk screen to enable the cup substrate to be tightly attached to the silk screen, then silk-printing liquid elastic glue, loosening the silk screen after silk-printing, and then stamping the other side of the cup substrate in the same way to obtain the cup substrate with two sides attached with the elastic glue;
D. hot press forming and trimming: and placing the cup matrix with the elastic glue attached to the two surfaces between the two fabrics, performing one-step hot press molding through a cup mold, and cutting and trimming to obtain the underwear cup.
Wherein, when impression liquid elastic glue, when compressing the cup base member to below half of former thickness, when compressing the cup base member more than half promptly, the inside air of cup base member is got rid of by the part, the fibre pastes tight silk screen, adhere to one deck liquid elastic glue on the fibre top layer after the silk screen printing, loosen the silk screen and make the cup base member resume original shape, it is inside that the air gets into, in the same direction as taking the liquid elastic glue on top layer to inhale inside and adhere to and form the rope form between the fibre, the wire drawing form, the operation can not form liquid elastic glue film and block up the gap influence gas permeability between the fibre on cup base member surface like this. The depth of the liquid elastic glue absorbed into the cup matrix is the thickness of the glue attaching area, which is comprehensively determined by the elastic glue viscosity, the fiber density, the cup matrix compression amount (i.e. the amount of the original volume compressed) and the like, and the thickness of the glue attaching area, especially the thickness of the high glue attaching area is closely related to the factors on the premise of meeting the requirement of no wrinkling according to the fiber structure characteristics.
When the operating viscosity of the elastic adhesive is more than 250000mPa · s, most of the elastic adhesive is adhered to the surface of the fiber due to too high viscosity of the elastic adhesive, and is difficult to be absorbed and adhered to the interior of the fiber, so that the rope-shaped and wiredrawing-shaped effects cannot be achieved, and the design requirements cannot be met.
Wherein the elastic glue viscosity is detected under the following conditions:
device name
HAAKE Roto Visco 1
Rotor
C20/1°
Test temperature
25℃
Rotational speed
10r/s
The detection equipment is commonly used in the industry, and the temperature, the rotating speed, the test method and the like of the test are all common means in the industry.
Before hot press molding and trimming, a layer of viscose can be printed on the bonding surfaces of the two fabrics, and the viscose can play a role in enhancing the bonding of the fabrics and the cup base body.
Wherein, when the silicon rubber is selected as the elastic rubber, the hot-press forming temperature is 120-200 ℃ and the time is 60-120 s. And (3) synchronously vulcanizing the liquid silica gel while hot-pressing to finally form a stable net-shaped structure.
The following description is given by way of specific examples:

The experimental method is that the experimental method,
1) toning the silica gel before printing (to detect the depth of penetration of the silica gel into the fibrous material);
2) measuring the thickness of the high adhesive area by using a vernier caliper after printing: taking the fiber surface layer as a reference point, and taking an obvious uniform position of the penetration color or the lowest penetration depth position as a measuring point; cutting the fiber material for multiple sampling measurements and calculating the average value to obtain the thickness of the high adhesive-attached area;
3) and weighing the newly added silica gel, namely weighing the fiber material before and after the fiber material is poor in quality.
Specification of indexes:
the silica gel is unqualified when the silica gel enters the fiber and the diameter of the silica gel is not more than 1.5 mm; 1.5 to 2mm is acceptable, 2 to 3mm is good, and 3 to 5mm is excellent.
And (4) experimental conclusion:
the weight of the newly added silica gel and the thickness of the high adhesive area are increased along with the reduction of the viscosity of the silica gel and the increase of the compression amount of the cup matrix.
