Comparison Of The Properties Of Milk Fiber And Other Fibers

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 better quality.

So what is the good thing about milk fiber?

In this period, the author compares the following aspects:

First, green environmental characteristics, milk fiber does not use formaldehyde azo AIDS or raw materials, fiber formaldehyde content is zero.

Soybean protein fiber is produced by the way of polyvinyl aldehyde, and contains more or less formaldehyde.

Milk protein has broad spectrum bacteriostatic function, strong persistence, mildew and moth proof than wool and cashmere. Its natural antibacterial function is over 99%, and its antibacterial rate reaches over 80%. These are not natural fibers such as cotton, silk, wool, cashmere and so on.

Second, in terms of fiber comfort, milk fiber has a cashmere like feel.

Milk fiber monofilament is finer and finer than bamboo fiber, pearl fiber and so on. Its specific gravity is lighter than wool, cotton and silk. Elongation at break, crimp elasticity and crimp recovery rate are most close to cashmere and wool.

The introduction of lactic acid bacteria on the basis of polyester fiber on the basis of polyester fiber, and the introduction of animal protein on the basis of acrylic fiber, makes the fiber more soft and soft, so the touch is soft, comfortable and smooth like cashmere, and its fiber is clear and has a silky natural luster and elegant appearance.

After testing, the Anti Japanese fastness and anti sweat fastness of the home milk fiber reached 3~4 grade, and its anti fuzzing and pilling ability reached 3 grade.

Third, moisture absorption and moisture conductivity, the permeability of milk protein fiber is far superior to other chemical fibers, such as polypropylene, polyester, acrylic, and even silk, because the section of milk fiber is irregular round, the section is full of gap, there are many grooves in the longitudinal direction, protein molecules are distributed on the surface of the fiber, contain natural protein moisturizing factor and a large number of hydrophilic groups, which can quickly absorb human sweat and quickly import air into the air through grooves to keep the skin dry and cool.

Fourth, in terms of endothermic exothermic aspects, the three dimensional porous structure of milk fiber and the groove structure on the longitudinal surface determine its characteristics of being warm in winter and cool in summer.

Because of the introduction of animal protein, milk fiber is better than the traditional acrylic fiber in its thermal insulation property, which is close to that of natural fiber cotton, slightly lower than wool.

Combined with the excellent moisture absorption and permeability of milk fiber, it can be made into thin fabrics in summer, absorb moisture from the skin quickly, and quickly spread into the air to keep the skin dry and breathable. In winter, thick fabrics are made, and the heat absorbed by the micropores is absorbed into the body, effectively blocking the air flow and preventing the cold air from invading.

Other characteristics of milk fiber also include: dyeing at room temperature and under normal pressure, the same as cotton fiber, cotton reactive dyes, bright coloured, soft and glossy, high dye uptake and 4 color fastness (the sample is produced by Shanghai Zheng Jia Milk Technology Co., Ltd.). After dyeing, it still has the original performance of the product. It has excellent safety in use. The fiber has high dry and wet strength and wet fastness than viscose fiber such as modal, Tencel and pearl fiber. It is durable, washable, easy to store, easy to dry after washing, and can maintain its permanent performance after washing.
