Description

Technical Field

[0001] The invention relates to the field of knitting, and in particular to a method for preparing a cationic polyester jacquard moisture-conducting knitted fabric. Background Art

[0002] In recent years, people have increasingly pursued a healthy lifestyle. As exercise continues regardless of season, post-exercise sweat management has become an important research topic. During exercise, the human body lowers its temperature to a comfortable level through perspiration. Typically, the human body maintains its core temperature at 37±1°C through dynamic thermal balance. However, when sweating profusely, intense exercise in high-temperature and high-humidity environments, or excessive sunlight exposure, heat accumulates on the body surface, causing clothing to stick to the body and significantly reducing comfort.

[0003] Most conventional synthetic fibers have poor hygroscopicity, but through physical or chemical modification, such as the introduction of highly hygroscopic polymers, surface modification, the formation of multi-microporous or grooved structures, etc., specifically by changing the shape of the spinneret, adding functional powders to the spinning solution, surface etching, special-shaped fiber blending, graft copolymerization and other methods of preparation, the moisture absorption and moisture conduction capacity of the fiber can be improved. Special-shaped fibers developed by changing the cross-sectional shape and internal structure of the fiber can increase the specific surface area of ​​the fiber, quickly absorb, transfer and evaporate sweat from the skin surface, and achieve the purpose of quick and easy drying. For example, hollow, cross, multi-lobed, grooved, C, Y-shaped cross-sections, etc. In addition, by changing the morphological structure of the fiber to have a microporous structure on the surface and inside, its capillary effect can also be enhanced to achieve the purpose of moisture absorption and quick drying.

[0004] By introducing high hygroscopic polymers or increasing the fiber capillary wicking capacity through fiber modification technology, composite spinning technology, and blended yarn processing technology, it is also possible to develop moisture-absorbing and moisture-conducting functional products. Foreign companies such as INVISTA, Teijin, Toyobo, Hyosung, and domestic companies such as Defulun and Yizheng Chemical Fiber have successively developed special-shaped polyesters by changing the cross-sectional shape and internal structure of the fibers. The products also have excellent unidirectional moisture-conducting properties. Product innovation is developing in the direction of better performance. Foreign countries started research and development of moisture-absorbing and perspiration-conducting fibers earlier, and the technology is more mature. For example, INVISTA's Moisture-wicking polyester fiber series products, Japan's TEIJIN's Sweatsensor microporous four-lobed cross-section polyester fiber, Japan's UNITIKA's "Hygra" fiber, etc. Summary of the Invention

[0005] This invention aims to develop a novel design concept for sports fabrics. By appropriately combining yarns with different hydrophilic and hydrophobic properties, a moisture-wicking fabric can be produced. During the weaving process, jacquard design can be used to rationally arrange the thickness, pattern, and elastic areas of the fabric. This allows the fabric to meet the body's requirements for breathability, lift, and elasticity while also providing a certain degree of moisture absorption and perspiration management.

[0042] ②:75D / 72F rainbow yarn

[0043] ③: 20D spandex

[0044] Weaving method: The loom is 34" 28G single-sided machine, and the needle arrangement is 12123434.

[0045] Triangular arrangement as Figure 1 .

[0046] The yarn arrangement is:

[0047] No. ①-⑨, The yarn is 100D / 144F cationic polyester, with a line length of 12.5cm / 50N and a yarn feeding ratio of 84.87%;

[0048] No. 10. The yarn is 75D / 72F Wuhong yarn, the yarn length is 12.5 / 50N, and the yarn consumption ratio is 7.06%;

[0049] No. The yarn is 20D spandex, the thread length is 4.8 / 50N, and the yarn feeding ratio is 8.07%;

[0050] Through traditional weaving, dyeing and finishing processes, a cationic polyester jacquard moisture-conducting fabric with a weight of 155g / m2 is obtained. 2 .

[0051] The moisture absorption is tested in accordance with GB / T 21655.1-2008. After washing, the air permeability and moisture conductivity are as follows: the water diffusion time is less than 1s, the water absorption rate is 157%, the wicking height is 156mm in the vertical direction and 146mm in the horizontal direction, the evaporation rate is 0.21g / h, and the moisture permeability is 1.02*104g / (m 2 24h).

[0052] Obviously, the fabric has good air permeability and moisture conduction properties, such as Figure 3 As shown, the fabric has a great design aesthetic.

[0053] Comparative experiment 1:

[0054] The same triangle arrangement, yarn sorting, weaving and dyeing and finishing process as in the embodiment are used, except that the yarns are different:

[0055] No. ①-⑨, The line is 100D / 144F polyester, and the line length is 12.5cm / 50N;

[0056] No. 10. The yarn is 75D / 72F Wuhong yarn, and the yarn length is 12.5 / 50N;

[0057] No. The line is 20D spandex and the line length is 4.8 / 50N.

[0058] Through the above weaving and necessary dyeing and finishing processes, the jacquard moisture-conducting fabric with a gram weight of 150g / m2 is obtained. 2 .

[0059] After testing, the air permeability and moisture conductivity after washing are: water diffusion time <1s, water absorption rate 152%, wicking height: vertical 137mm, horizontal 136mm, evaporation rate 0.20g / h, moisture permeability 1.01*104g / (m 2 24h).

[0060] The fabric has good air permeability and moisture conduction performance, but the color of the fabric is not as bright as that of Example 1. Figure 4 As shown, the fabric has a dull appearance and poor aesthetic effect.

[0061] Comparative experiment 2:

[0062] The same yarn and dyeing and finishing process as in Example 1 are used, except that the triangles of the weaving are arranged (e.g. Figure 2 shown):

[0063] The first line is 100D / 144F cationic polyester, with a line length of 12.5cm / 50N;

[0064] The second route is 75D / 72F Wuhong yarn and 20D spandex, with line lengths of 12.5 / 50N and 4.8 / 50N respectively.

[0065] Through the above weaving and necessary dyeing and finishing processes, the jersey fabric with a gram weight of 165g / m2 is obtained. 2 .

[0066] After testing, the air permeability and moisture conductivity after washing are: water diffusion time <1s, water absorption rate 146%, wicking height: vertical 133mm, horizontal 135mm, evaporation rate 0.18g / h, moisture permeability 0.97*104g / (m 2 24h).

[0067] The fabric has certain air permeability and moisture conduction properties, no jacquard process, the fabric is thick and delicate, and the air permeability is slightly poor.

[0068] The effects and functions of this embodiment are as follows:

[0069] From the above embodiments, it can be found that the knitted fabric with floating threads made of cationic polyester, rainbow yarn and spandex and woven with jacquard structure has a soft texture, is skin-friendly but not sticky, has good wrinkle resistance and breathability, and has greater extensibility and elasticity, thereby improving the comfort of wearing.

[0070] From the above embodiments, it can be found that by changing the weaving method and weaving the three fibers into a textured jacquard structure, moisture can be evaporated quickly, the air permeability and wicking effect of the fabric can be improved, and the water vapor on the inside of the fabric can be quickly transferred to the outside of the fabric.

[0071] From the above embodiments, it can be found that cationic polyester can replace the yarn-dyed two-color fabric, thereby reducing the cost of the fabric, which is in line with the development trend of new materials in the future.

[0072] From the above embodiments, it can be found that cationic polyester and Wuhong yarn are dyed to produce a two-color effect. The combination of two colors and jacquard enhances the layering and texture of the wearer. The fabric has good drape and is not easy to wrinkle. It is used as a fabric for sports such as yoga, which is a change from the commonly used solid colors and has pleasing beauty and practicality.
