Fabric Auxiliaries: Wear Moisturizing And Moisturizing Skin Care Products (1)

At present, it is widely known that collagen is the beautician of skin. Therefore, collagen capsules, facial mask and skin care products are emerging one after another. Is it possible to integrate collagen into clothing fabric so that all skin can enjoy the care of collagen? The answer is yes.

Donghua Textile Group's top quack Color Cotton Clothing Co., Ltd. has developed an environmentally friendly and functional fabric auxiliaries - collagen softener and its finishing process, and has been successfully applied to the top colored melon underwear and its series products, so that the top underwear is not only made of green cotton products because of colored cotton, but also has the function of moisture absorption and moisture retention due to the use of collagen softener.

Donghua Spin How does the group perfectly link the green colored cotton fabric with moisture absorbing, moisturizing and skin care collagen? We invite Yu Changsong, deputy general manager of Donghua color cotton Engineering Technology Research Center Co., Ltd. to open the secret for readers.

Moisturizing and moisturizing skin care products

Moderator: Yu, would you like to introduce the characteristics of collagen and the current use of collagen in textiles?

Yu Changsong: Collagen protein It is a spiral fibrous protein twisted by three peptide chains. It exists in animal body. It has very strong quick water absorption. Its own three glue spiral structure can firmly lock moisture and bring long moisturizing and nursing effect to the skin. At the same time, collagen is rich in 18 kinds of amino acids, high nutritional value and strong function. It is a good natural physiological active substance. At present, it is mainly used in cosmetics (external application) and health care products (oral), and its use in textile and clothing is relatively rare. Foreign countries such as the United States, Germany and Japan, Korea and other countries use collagen fabric made of fabrics and clothing have been put on the market, and have been welcomed by consumers. Collagen softeners for textile fabrics have also been released, representing products such as Japan's TASTEX SKU-C and Korean BOOWON BOO TEC cl-collagen.

Moderator: at present, only a few countries in the world use collagen on textiles, is it because it is technically difficult?

Yu Changsong: there are several factors. On the one hand, the demand for green textiles in developed countries has promoted the research of textile environmental protection auxiliaries and their technology. On the other hand, the application of collagen to textile fabrics is technically difficult, as well as the level of economic development and the habit of consumption.

Collagen fibers can be prepared by wet spinning. The fabric and clothing made of this fiber or its blended fiber retain some of the properties of natural collagen. Therefore, collagen has good affinity with human skin, and has strong moisture retention and comfortable clothing. However, collagen fibers are easy to degrade in higher temperature solutions, and their spinnability is poor. The resulting textiles have poor strength, hot water resistance, acid and alkali resistance and poor dry heat performance, which are difficult to meet the requirements of application, and their application and popularization are affected.

Collagen is added as a functional assistant to fabric. This can give the fabric the characteristics of collagen, such as hydrophilicity, moisturizing, skin care and itching, and make the body clothing more comfortable. In addition, because of the external addition, the physical and chemical properties of the fabric have not changed much, and will not affect its performance. Therefore, the research and development of low molecular weight, water-soluble collagen softeners and functional finishing technology has become a new research direction at home and abroad.

After finishing with collagen softener, the fabric has good moisture absorption and moisture retention, no chemical irritation on the skin, and its fabric feels close to nature and is healthy, comfortable and environmentally friendly. However, there is a certain difference between the handle and silicone softener treatment, and the durability of collagen containing proteins usually decreases with the increase of washing times. In particular, we should mention that Chinese people have a certain preference for organosilicon chemical softener products. These are the topics to be further solved in the study of collagen functional finishing technology and fabrics.

Crack three technical problems

Moderator: it is understood that the fabric developed by Donghua Textile Group is made of collagen softener, and its water absorbency is: after treatment, the fabric has a wool effect of >10cm/30min, moisture retention: fiber moisturizing degree >400%, softness: reaching the conventional soft finishing feel, durability: washing up to 20 times, safety: pH value 4 ~ 7.5, formaldehyde content less than 75mg/kg, harmful metal content conforming to the corresponding national standard GB/T18885-2002 (ECO textile technical requirements), wearability: conform to the national standard of GB/T 8878-2002 "cotton knitted underwear", to achieve these technical indicators, what breakthroughs have been achieved in the key technologies of the company?

Yu Changsong: our company has been working with South Korea Fuyuan Biotechnology Co., Ltd. since 2007 to develop collagen softeners and fabric finishing items. Now we have focused on solving three technical problems.

The first is the ecological and environmental friendly pretreatment of colored cotton fabrics. Because natural coloured cotton contains a lot of organisms such as cotton wax, ash and pectin, it is necessary to deal with the common organisms and impurities of colored cotton cellulose under the premise of ensuring the color and performance of the colored cotton, so as to ensure that the collagen finishing agent can infiltrate into the colored cotton fabric very well.

The two is to solve the problem of poor adsorption fastness of collagen. Collagen is composed of a variety of amino acids. It has two affinity characteristics of hydrophilic and lipophilic. Although it can be adsorbed onto the fabric through molecular force between fibers, it is not resistant to washing. Its hydrophilic and moisturizing effect will be greatly reduced after several washing. In order to solve the problem of poor adsorption fastness, we use nano scale binding agent to penetrate into the fiber deeply, and bind tightly with the fibers through cross-linking reaction, so that the carboxyl groups extending to the fiber surface can absorb water and protect skin. After proper molding process, the function can be washed 20 times without failure.

Three, based on the use of the collagen cl-collagen solvent of South Korea Fuyuan Biotechnology Co., Ltd., in cooperation with the Korean Macquarie Biological Development Co., Ltd., the ratio and finishing process of collagen softener were further improved, and the stable collagen softener soaking, rolling, drying, shaping process, process plan and technological parameters were optimized.
