Abstract
Using mica/bamboo pulp fiber blended yarn as raw material and based on the theory of fabric thermal comfort and fiber moisture conductivity, plain weave, fancy perforated, twill and Moisture-absorbing and quick-drying cooling fabric with 4 kinds of wheat grain structure. At the same time, the basic wearing properties and moisture-absorbing, quick-drying and cooling properties of these four kinds of fabrics were tested. The analysis showed that the four developed fabrics all have moisture-absorbing, quick-drying and cooling properties, among which the wheat grain tissue has the best moisture-absorbing, quick-drying and cooling properties. Fabric.
In recent years, cool fabrics have been favored by consumers. “Cool” means refreshing, which means that the fabric can quickly cool down the human body; “shuang” means dry, which means that the fabric quickly discharges different forms of sweat produced by the human body into the fabric through wicking, diffusion, transmission, etc. The outer layer then evaporates, which is commonly referred to as moisture wicking properties [1-3].
Mica cooling fiber is a new type of cooling and heat-dissipating fiber. Its melting point is as high as 1300℃ and is stable below 550℃. The thermal conductivity rate of mica is more than 5 times that of polyester. In addition, the surface of mica is charged, so the water content is extremely high. The water needs to be removed above 500°C [4]. In this way, the high water content also drives the cooling effect, so Mica fiber has the function of “high thermal conductivity + high heat absorption effect” [5].
Bamboo pulp fiber combines the excellent properties of natural fibers and man-made fibers. It has excellent air permeability and moisture permeability. It is called a breathable fiber by industry insiders [6]. In addition, it has natural anti-odor properties and good antibacterial properties.
Therefore, this experiment uses mica/bamboo pulp fiber blended yarn as raw material to design and develop 4 kinds of moisture-absorbing and quick-drying cool fabrics with different organizational structures. The basic wearing performance and moisture absorption, quick drying and cooling performance of this tissue structure [7-8] were tested, and the fabric with the best moisture absorption, quick drying and cooling performance was selected.

The test standards and methods are tested according to GB/T4802.1-2008 “Determination of Pilling Properties of Textile Fabrics Part 1: Circular Trajectory Method”.
2.1.4 Drape test
Fabric drape test The experimental instrument used is the YG811 fabric drapability tester (Quanzhou Meibang Instrument Co., Ltd.). The test standards and methods refer to GB/T23329-2009 “Testing of Drapability of Textile Fabrics”.

2.2.3 Thermal insulation test
The thermal insulation test of fabrics The experimental instrument adopts YG606D flat-plate fabric thermal insulation instrument (Ningbo Textile Instrument Factory). The test standards and methods refer to GB11048-1989 “Test Method for Thermal Insulation Performance of Textiles”.
2.3 Fabric moisture absorption and quick drying test
2.3.1 Core Absorption height test
The experimental instrument for fabric wicking height test adopts YG(B)871 capillary effect measuring instrument (Wenzhou Darong Textile Standard Instrument Factory). Test standards and methods refer to ZBW04019-1990 “Textiles Capillary Effect Test Method”The structure and fiber raw materials are closely related. Since the experiment used bamboo pulp and mica fiber with high moisture absorption and perspiration, these four fabrics all have good moisture absorption and quick drying properties, while the average floating length of the wheat grain structure is longer. There are fewer tissue points, so the wheat grain tissue has the best quick-drying properties, followed by the twill tissue, the fancy perforated tissue is better, and the plain weave tissue has poor quick-drying properties.
Comprehensive comparison of the moisture absorption and quick-drying performance indicators of fabrics with four tissue structures shows that the moisture absorption, quick-drying and cooling properties of wheat grain tissue are the best than those of the other three types of tissue.
Conclusion
a) With 50/50 mica/bamboo Using pulp blended yarn as raw material, the four woven fabrics designed and developed: plain weave, fancy perforated weave, twill weave and wheat grain weave, all have the function of moisture absorption, quick drying and coolness;
b) Testing the basic wearing properties of four kinds of fabrics shows that: the abrasion resistance of wheat grain tissue is worse than that of twill weave, fancy perforated and plain weave, and the breathability is worse than that of twill weave, floral weave and plain weave. The plain weave is better than the fancy through-hole, twill weave and wheat grain weave;
c) Testing the moisture-absorbing, quick-drying and cooling properties of fabrics with four tissue structures shows that: the performance tests of thickness, thermal resistance, moisture resistance, and thermal insulation reflect the cooling characteristics of moisture-absorbing, quick-drying and cooling fabrics, and it can be seen that the cooling properties of the wheat grain tissue is the best. The performance tests of wicking height, maximum diffusion radius and liquid diffusion speed reflect the moisture-absorbing, quick-drying and cooling properties of the fabric. It can be seen that the crispness of the wheat grain structure is the best.
In summary, the structural parameters for developing moisture-absorbing, quick-drying and cool fabrics are: warp and weft yarn density Both are 7.38tex×2, the warp and weft density are 337 threads/10cm and 276 threads/10cm respectively, and the fabric structure is wheat grain tissue. </p
