Abstract

The multi-functional and cosmetic fiber was developed in this paper which in response to the Kyoto Protocol and a number of international climate conference thinking regarding energy conservation, year-on-year reduction of carbon emissions and carbon. Using wet ball milling to grind, disperse, and modify the cooling mineral stone powder and extracting collagen, and then make caprolactam mix cooling powder and collagen filler through ring open reaction, and in-situ polymerization to fabricate nylon 6 slices with cooling powders and formula collagen for melt spinning as 120d/68f cooling collagen Partial Oriented Yarn (POY), then make a 70d/68f cooling collagen Draw Textured Yarn (DTY) through drawing and false twist processes. Finally, single jersey and double face knitted fabrics with cooling and collagen were fabricated by 32G and 28G circular machine. The spring and summer women’s underwear and casual wear are designed as the product, and the related physical and chemical properties (washing dyeing fastness test faded and stained, shrinkage rate, free formaldehyde content, etc.) and functional properties (instant cool heat flow, UPF, static thermal image, water absorption height, 40-minute residual moisture rate, water absorption area, etc.). The experimental results show that the physical and functional properties can meet the basic requirements of women’s underwear and casual wear in spring and summer. The development of spring and summer women’s underwear and casual wear is in line with the industrial upgrading and transformation and industry innovation research and development theme, including the combination of upstream (functional fiber), midstream (yarn, fabric), downstream (dyeing and finishing) industry and women’s products to integrate cooperated supply chain. Textile Enterprise Co., Ltd. is the market leader in the international underwear knitwear market and combined with a number of international brands to promote this underwear and casual apparel international market which have multi-tone. moisture keeping, cooling feeling, beauty and anti-UV functions.

Introduction

In recent years, the research on cooling comfort and collagen textiles is mainly in the field of underwear and casual wear. The collagen is more important in the fields of health food, cosmetics, medicine and man-made fiber. In the field of collagen textile fiber production in recent years, the additive is mainly composed of papolis, collagen extracted from milkfish scales, bone-extracted collagen, and artificial collagen [1]. Collagen is a natural substrate in the natural ecology, which has the following three aspects of health effects on the human body. 1. Comfort - collagen is composed of 18 kinds of amino acids, which has excellent biocompatibility with the human body. 2. It has humidity regulation function, because collagen is rich in hydrophilic groups such as many amine groups (-CONH) and amino groups (-NH2), the structure is porous, easy to diffuse water molecules, and can be adjusted in humid air as well as have a certain amount of water. 3. Tryptophan and Tyrosine in collagen absorb ultraviolet rays, and ultraviolet rays are harmful to the skin, so collagen can protect the skin from ultraviolet light radiation [2-7].

Although the above description shows that collagen has so many advantages and functions, there are few reports and paper on the application of collagen in viscose rayon staple fibers and nylon 6 filament yarns. There is no clear explanation on how to overcome the heat resistance of collagen. Collagen detection cannot be performed quantitatively even in yarns and fabrics. Since the activity and heat resistance of collagen may be destroyed during master batch, spinning, dyeing, and setting stages, the functionality of the fiber products was affected. Due to the problems of collagen yellowing, heat resistance, mold and activity loss caused by high temperature production, this paper uses the special collagen formula and the in-situ polymerization method of the innovative process to overcome the above [8] problems and enhance the performances of collagen nylon 6 fibers such as heat resistance, durability, moisture retention,skin-friendly and comfort, etc., and have higher added value and economic benefits.

Experiment

The fabrication of polyamie 6 with collagon and cooling is made from in-situ polymerization and through melt spinning methos to produce the Partial Oriented Yarns (POY) with 120d/68f. Furthermore, the 70d/68f Draw Textured Yarn (DTY) was made from Murata nip twister false twist machine [8]. Table 1 shows the DTY content, density, fabric weight and width of three different collagens woven by a 28G, 32G circular knitting machine made of 70d/68f collagen PA6 extended false twisted yarn (DTY). The finished fabric is finished by scouring, bleaching, pre-setting, dyeing, finishing and heat setting processes, and the physical and functional properties described herein are all cool collagen finished fabrics.

Result and Discussion

Comparison of physicochemical properties of cooling collagen circular knitted fabric

Notes: WD: Warp Direction; FD: Filling Direction

Table 2 shows the results of the fading and staining, shrinkage and free formaldehyde content of cooling collagen knitted fabrics with different gauges. The measured values in Table 2 can reach the spring and summer females basic requirements for international brands of underwear and casual wear

The functional properties of circular knitted fabrics

The functional properties of the two circular knitting fabrics with different gauges and knitted fabric weights are shown in Table 3. The air permeability of the knitted fabrics is gradually increased as the fabric weight and density increase according to the ASTM D 737 testing standard. Since both fabrics have inlaid an elastic fiber (Spandex fiber) about 16 wt.%, there is an elastic recovery rate of more than 120%, so there is no fear in air permeability and wearing comfort problem. The FTTS-FA-004 test specification was draw up Functionality and Industrial Textiles Certification and Verification Review Committee in Taiwan. According to the FTTS-FA-004 test specification, the water absorption area, water absorption height and residual moisture content of 40 minutes show that the higher water absorption area has a higher water absorption performance with the increase of fabric weight and the amount of cooling collagen yarn. In the anti-ultraviolet light according to the AATCC 183 test standard, as the weight and density of the fabric increase, the anti-ultraviolet resistance of the knitted fabric gradually increases. In the static thermal image temperature difference according to the FTTS-FA-010 test specification, as the fabric weight and density increase, the thermal image temperature difference of knitted fabrics gradually increases. The multiple

functions meet the basic requirements of women’s underwear and casual wear in spring and summer. Furthermore, the instant cooling feeling value (Qmax) of the FC 232215 knitted fabric better than the nomenclature FC 32781. It is probably because that the higher cooling collagen yarn content has better performance of the knitted fabric.

Conclusion

The multi-functional and cosmetic fiber was developed successfully in this paper which in response to the Kyoto Protocol and a number of international climate conference thinking regarding energy conservation, year-on-year reduction of carbon emissions and carbon. The single jersey and double face knitted fabrics were fabricated by 32G and 28G circular machine. The spring and summer women’s underwear and casual wear are designed as the product, and the related physical and chemical properties (washing dyeing fastness test faded and stained, shrinkage rate, free formaldehyde content, etc.) and functionality (instant cool heat flow, UPF, static thermal image, water absorption height, 40-minute residual moisture rate, water absorption area, etc.). The experimental results show that the physical and functional properties can meet the basic requirements of women’s underwear and casual wear in spring and summer. The development of spring and summer women’s underwear and casual wear is in line with the industrial upgrading and transformation and industry innovation research and development theme, including the combination of upstream (functional fiber), midstream (yarn, fabric), downstream (dyeing and finishing) industry and women’s products to integrate cooperated supply chain. Textile Enterprise Co., Ltd. is the market leader in the international underwear knitwear market and combined with a number of international brands to promote this underwear and casual apparel international market which have multi-tone. collagen beauty and anti-UV functions [9-11].
