Background

When daily life or outdoor exercises, the excreted sweat of health can be absorbed by the cloth, and after the dress that ordinary cloth made absorbed the sweat, vegetable fibre can expand and block up the cloth through-hole, can make sweat and cloth paste on human skin, the evaporation of can't discharging rapidly of sweat.

The fabric is used for one-way moisture transmission, which means that moisture or sweat flows from the inner layer of the fabric to the outer layer of the fabric and evaporates and diffuses in the outer layer, and meanwhile, the moisture or sweat of the outer layer is difficult to permeate back to the inner layer. The mechanism of one-way moisture conduction of the fabric is a capillary effect caused by pressure difference, and liquid moisture in the fabric automatically diffuses from the inner layer to the outer layer under the action of the capillary effect and the pressure difference.

The current way of realizing unidirectional moisture conduction of fabrics can theoretically start from two aspects: firstly, the diffusion speed of the surface of the fabric is enhanced, and the evaporation area of sweat or moisture is increased; and secondly, the capillary effect of the fabric is increased, namely the capillary effect is enhanced through the increase of the capillary channels. Therefore, the adhesion feeling between the fabric and the skin of the human body can be reduced, and the comfort level is improved. In practical operation, a plurality of manually controlled windows are provided for the clothes in a mode of zippers and the like so as to achieve the purposes of heat dissipation and moisture removal, and the method is also a common means.

The method comprises the following steps: s1, removing impurities from the cotton fibers, soaking the cotton fibers in a water clarifier for hydrophilic treatment, taking out the treated cotton fibers, drying and spinning to obtain hydrophilic cotton yarns; s2, removing impurities from the cotton fibers, soaking the cotton fibers in a hydrophobic agent for hydrophobic treatment, removing the treated cotton fibers, drying and spinning to obtain hydrophobic cotton yarns; blending hydrophilic cotton yarn and water-soluble fiber to obtain mixed cotton yarn, wherein the blending ratio of the clean water cotton yarn to the water-soluble fiber is 1: 0.3-0.4; s3, mixing the mixed cotton yarn and the hydrophobic cotton yarn 1: 1, mixing and spinning to obtain a mixed fabric; weaving hydrophilic cotton yarns to obtain hydrophilic cloth, and sewing the hydrophilic cloth and the mixed fabric to obtain moisture-conducting cloth; and S4, placing the moisture-guiding cloth in a cleaning tank, and stirring and cleaning to obtain the finished cloth. The cloth prepared by the method can be used for preparing clothes, and has unidirectional moisture permeability. In the technical scheme, the hydrophilic cloth is sewn with the mixed fabric to obtain the moisture-conducting cloth; and the mixed fabric is obtained by mixing and spinning the mixed cotton yarn and the hydrophobic cotton yarn.

In the prior art, in another mode, a cloth material with a main (60% -100%) component being a Polyester (english Polyester) material is selected, and then the cloth material is coated on the surface of the cloth material through a liquid auxiliary agent in a post-finishing stage, and a small amount of the liquid auxiliary agent permeates the surface of the cloth material, so that a unidirectional moisture-conducting effect is achieved. The mode is that the cloth has the moisture-conducting effect through the coating and the coating of the auxiliary agent, the actual controllability of the function is unstable, and the effect of the unidirectional moisture-conducting function is good or bad. And because the production process of coating and coating on the surface of the cloth is adopted, the unidirectional moisture-conducting function is gradually lost after the actual clothes are worn and washed.

The invention relates to a preparation process of dynamic warm clothing with unidirectional moisture conduction, which is realized by the following technical scheme.

The dynamic thermal garment is made of a unidirectional moisture-conducting fabric, and the unidirectional moisture-conducting fabric comprises three layers of materials, specifically comprises a surface layer, a thermal layer and a lining layer;

the surface layer needs to be made of unidirectional moisture-conducting woven fabric, and the fabric is characterized by being of a single-layer double-density structure, and the surface structure can be any of all cotton, polyester, nylon yarns or yarns; the inner structure can be polypropylene yarn; or parallel spandex covered yarns; or polyester, nylon yarns or parallel spandex-coated yarns modified by a hydrophobic agent. The fabric has a physical one-way moisture-conducting effect because the fabric is a single-layer fabric woven by a double-layer structure, has no special requirements on the traditional processing and cutting, and also has the physical antibacterial property if the inner structure is polypropylene.

The warm-keeping layer can be all-cotton puffed cotton velvet flowers, polyester fiber puffed chemical fiber velvet flowers, or duck down and goose down velvet flowers;

further, during the filling and processing, the front and back sides of the filling material are hung with blocky non-woven fabrics, and the down flowers of natural organisms are treated with down penetration prevention down bags.

The lining layer is the same as the surface layer; furthermore, the metal conductive yarns are spaced at intervals of 2cm-5cm in the weft yarn direction of the lining layer, and are used for weakening high-voltage electrostatic groups generated when chemical fiber materials rub against a human body.

Furthermore, the surface layer of the technical scheme of the invention needs to use the unidirectional moisture-guiding woven fabric not less than 45d, and the fabric is characterized by a single-layer double-density structure, the surface structure can be any of all cotton, terylene, nylon fdy yarn or dty yarn, the lining structure can be 45d-75d dty polypropylene yarn or parallel 20d spandex coated yarn, 45d-75d terylene modified by a hydrophobic agent, and nylon dty yarn parallel 20d spandex coated yarn;

In addition, the processing method of the technical scheme of the invention has strict requirements on the processing sequence of the surface fabric, firstly, the surface unidirectional moisture-conducting fabric must be marked clearly according to the front and back sides to avoid the loss of the functionality of the processed finished product caused by the misoperation of the table top, because the fabric is single-layer double density, the inside and the outside are homochromatic and have no chromatic aberration under the condition of adopting a chemical hydrophobic agent, thus the front and the back are easy to reverse during processing to cause the loss of the function of the finished product, if the polypropylene yarn is adopted as the fabric for the inside, the front and the back chromatic aberration is large, and the single-layer double colors are easy to distinguish.

The specific implementation of the processing method for the middle heat-preservation filling material only needs to process the middle heat-preservation filling material according to the traditional heat-preservation filling material, and the front side and the back side do not need to be distinguished.

The specific implementation of the processing method has strict processing sequence requirements on the lining unidirectional moisture-conducting fabric as the surface fabric, otherwise, the finished product does not have the above functionality after being processed.

2. The invention can thoroughly solve the problem of difficult antistatic of traditional thermal clothes, and the lining unidirectional moisture-conducting fabric weft yarns are parallel to the metal conductive yarns, so that the dynamic unidirectional moisture-conducting fabric has a dynamic unidirectional moisture-conducting function and simultaneously has a sufficient antistatic effect on high-voltage static electricity caused by friction between a human body and clothes, the damage of electrostatic groups to the human body is avoided, and the generation of accidental safety accidents caused by static electricity in winter is also avoided.

3. The invention can thoroughly solve the problem that the armpit ventilating window or the chest ventilating window needs to be additionally designed due to moisture accumulation caused by poor moisture removal of the traditional warm-keeping clothes products, and because the finished products have real-time dynamic moisture removal and heat preservation, any additional ventilating window does not need to be designed, thereby reducing the processing links, reducing the processing cost and simultaneously improving the processing speed.

4. The invention can thoroughly solve the problem of bulkiness and swelling of the traditional warm-keeping clothes, and has the characteristics of lightness, warmth retention, air permeability and the like because of having the real-time dynamic one-way moisture-conducting function and not needing to design an additional ventilation window, the real-time dynamic one-way moisture-conducting function also reduces the requirement on the Crohn value (calorific value) of the intermediate filler, and simultaneously, the warm-keeping calibration temperature range does not change, so that in the actual test, the temperature is minus 10-minus 15 ℃, and 200g/M of trunk filling is filled²The sleeves are filled with 120g/M²Blast cap filling 120G/M²And under the condition of 6-grade wind, the body can resist the wind, snow and cold weather condition only by one t-shirt, so that the dressing burden of the human body is greatly reduced.

5.

Example 3 heavy unidirectional wet-wicking dynamic thermal garment preparation

FIG. 2 is a schematic cross-sectional view of a five-layer unidirectional moisture-wicking fabric used to make the heavy-duty unidirectional moisture-wicking dynamic thermal garment of the present invention; as can be seen from fig. 2, the unidirectional moisture-conducting fabric thus comprises a surface layer 1, a first thermal insulation layer 21, an intermediate layer 4, a second thermal insulation layer 22 and a lining layer 3; the surface layer 1 is used as the outer layer fabric of the heavy one-way moisture-conducting dynamic thermal garment, and the lining layer 3 is used as the inner layer fabric of the heavy one-way moisture-conducting dynamic thermal garment; wherein the first thermal layer 21 is located between the surface layer 1 and the interlayer 4; the second warm-keeping layer 22 is positioned between the middle interlayer 4 and the lining layer 3; the middle interlayer 4 is located between the first heat preservation layer 21 and the second heat preservation layer 22 and is used for separating the first heat preservation layer 21 from the second heat preservation layer 22.

According to fig. 4, when the first heat-insulating layer 21 and the second heat-insulating layer 22 of the middle heat-insulating filling material, the middle interlayer 4 and the lining layer 3 of the unidirectional moisture-conducting fabric are sewn into a semi-finished product of a sandwich structure, the front and back directions of the fabric of the sandwich structure must be strictly checked, the surface with the antistatic yarns faces the human body, then the surface layer 1 of the surface fabric starts to be sewn, and the back surface of the surface layer 1 must face the human body as the same as the fabric of the lining layer 3.

GB/T11048-2018 and GB/T5453-1997 are the latest national standards.

This measurement is completed by a third-party detection mechanism.

Wherein samples 1-4 correspond to the products of examples 1-4, respectively; samples 1 and 2 are lightweight, unidirectional, moisture wicking, dynamic thermal garments described in examples 1 and 2; samples 3 and 4 are heavy one-way moisture wicking dynamic thermal garments described in examples 3 and 4; the sample 1 and the sample 2 are M-type ready-made clothes, and the filling amount is 198-200 g; samples 3 and 4 were M-type garments at a loading of 248-250 grams.

The normal version of the short men's down jacket with the normal 90% goose down/700-800 fluffs has 200g of static sitting resistance of about 10 degrees, namely the Crohn value is about 2.3;

the sample 1 and the sample 2 are used as light unidirectional moisture-conducting dynamic thermal clothes, the Crohn values of the dynamic thermal clothes are respectively 2.78 and 2.74, namely compared with the male short-version down jacket with 90% of duck down, under the condition of the same filling amount, the Crohn values are respectively improved by 20.8% and 19.1%, and the sample 1 and the sample 2 are superior to the male short-version down jacket with 90% of duck down. Samples 1 and 2 are suitable for use in a daily environment at-15 ℃ to 10 ℃ and are less padded than conventional insulating cotton garments over the same warm temperature range.

Samples 3 and 4 were used as heavy unidirectional moisture wicking dynamic thermal garments with a respective cromet value of 3.56 and 3.42, i.e., the cromet values were increased by 54.8% and 48.7% respectively, compared to the above 90% duvet down garment of the male short normal version, samples 3 and 4 were more suitable for use at ambient temperatures of-30 ℃ to-10 ℃, and were less padded than conventional thermal cotton garments at the same range of thermal temperatures.

From the data, compared with the light unidirectional moisture-conducting dynamic thermal insulation garment sample, the heavy unidirectional moisture-conducting dynamic thermal insulation garment sample has lower thermal conductivity, higher relative heat preservation rate and relatively reduced air permeability, because the intermediate interlayer 4 and the second thermal insulation layer 22 are added to the heavy unidirectional moisture-conducting dynamic thermal insulation garment, and the result is in line with the expectation.
