Structure And Properties Of Milk Protein Fibers

Structure and properties of milk protein fibers

1.The formation of milk protein fiber

Milk protein fiber is a kind of cheese protein with linear macromolecular structure after dehydration, deoiling, degreasing, separation and purification. The spinning stock was prepared by blending, crosslinking and grafting with polyacrylonitrile by high-tech means. Finally, by wet spinning into fiber, curing, drawing, drying, crimping, setting, short fiber cutting (filament winding)

2.Properties of milk protein fiber

(1) Green environmental protection features

Do not use formaldehyde azo and other additives or raw materials, fiber formaldehyde content is zero; Rich in 18 kinds of amino acids beneficial to human milk fiber products, can promote human cell metabolism, prevent skin aging, itching, nutrition skin; With natural moisturizing factor, it can keep skin moisture content, make skin soft and smooth, reduce wrinkles, with broad spectrum antibacterial function, strong persistence, antibacterial rate of more than 80%.

(2) Fiber comfort

With cashmere feel, its monfilaments are fine in size, light in specific gravity, elongation at break, crimp elasticity and crimp recovery rate are closest to cashmere and wool. The fibers are puffed up and soft, and feel as soft, comfortable and slippery as cashmere. Fiber white, with silky natural luster, elegant appearance.

(3) Hygroscopic and exothermic

Milk protein fiber cross section for the irregular circular, in the cross section is full of space, there are many grooves, the longitudinal distribution of protein molecules on the surface of fiber, protein contains natural moisturizing factor and a large number of hydrophilic group, can rapidly absorb human body sweat, through the groove quickly import in the air, make the person's skin to keep dry.Made of lightweight fabric in summer, it can quickly absorb the wet sweat from the skin and quickly spread into the air to keep the skin dry and breathable; Made of thick fabric in winter, microporous absorb the heat from the body, effectively block air circulation, prevent cold air invasion, light and warm.
