Comparison of milk fiber and other fiber properties
The appearance of milk protein fiber has changed the traditional definition of animal protein fiber. It has the advantages of natural fiber, chemical fiber and good quality. Then someone asked, where is the milk fiber? In this issue, the author compares the following aspects:
First, in terms of green environmental protection characteristics, milk fiber does not use formaldehyde azo additives or raw materials, and the fiber formaldehyde content is zero. Soy protein fiber is produced by vinylon hydroformylation, which contains more or less formaldehyde. Milk protein has a broad-spectrum antibacterial function, strong persistence, mildew and anti-mite than wool and cashmere, natural antibacterial function of more than 99%, antibacterial rate of more than 80%, these are natural fibers such as cotton, silk, wool, cashmere do not have.
Second, in terms of fiber comfort, milk fiber has a cashmere feel. Milk fiber monofilament fineness, strength is greater than bamboo fiber, pearl fiber, etc., specific gravity is lighter than wool, cotton, silk, etc., and elongation at break, curly elasticity, and curl recovery are closest to cashmere and wool. Corn fiber introduces lactic acid bacteria on the basis of polyester, and milk fiber introduces animal protein on the basis of acrylic fiber, which makes the fiber more delicate and soft, so the touch is soft, comfortable and smooth like cashmere; the fiber is white and silky. Natural luster and elegant appearance. After testing, the anti-sun fastness and anti-perspiration fastness of Zhengjia milk fiber reached 3~4, anti-pilling and pilling reached level 3.
Third, in terms of moisture absorption and moisture permeability, the moisture permeability of milk protein fiber is far superior to other chemical fibers, such as polypropylene, polyester, acrylic, and even silk, because the cross section of milk fiber is irregular and round, and the section is covered with voids. There are many grooves. The protein molecules are distributed on the surface of the fiber. They contain natural protein moisturizing factors and a large number of hydrophilic groups. They can quickly absorb human sweat and quickly introduce into the air through the grooves, so that the skin is always dry.
Fourth, in terms of heat absorption and heat release, the microporous structure of the milk fiber and the groove structure of the longitudinal surface determine the characteristics of winter warm and cool summer. Because of the introduction of animal protein, milk fiber is warmer than traditional acrylic fiber, which is similar to natural fiber cotton and slightly lower than wool. Combined with the excellent moisture absorption and permeability of milk fiber, it is made into light and light fabric in summer, quickly absorbs the moisture and sweat released from the skin, and quickly spreads into the air to keep the skin dry and breathable. In winter, it is made into thick fabric, and the micropores absorb the heat emitted from the body. It effectively blocks air circulation, prevents cold air from invading, and keeps warm and light.
Other characteristics of milk fiber include: dyeing at normal temperature and pressure, the same as cotton fiber, using cotton-type reactive dye, bright color, soft and lustrous, high dyeing rate, color fastness up to 4 (sample is Shanghai Zhengjia milk Silk Technology Co., Ltd.), after dyeing, still maintain the original performance of the product, with excellent safety; the fiber has high dry and wet strength, and the wet fastness is higher than that of modal, celestial, pearl fiber and other viscose fibers. It is washable, easy to store, easy to dry after washing, and can maintain the permanent performance of the product after washing.
