The real milk silk fabric is not easy to pilling. The milk silk fabric has a cashmere-like feel, its monofilament fineness is fine, its specific gravity is light, its elongation at break, curl elasticity, and curl recovery rate are the closest to cashmere and wool, and the fibers are bulky. Soft, soft, comfortable and smooth like cashmere; the fibers are white, with a silky natural luster, elegant appearance, anti-pilling fastness, anti-sun fastness, anti-perspiration fastness up to 4~3 grades, and easy to use Let dry. The cross section of milk protein fiber is irregular and round, and the cross section is full of voids and there are many grooves in the longitudinal direction. The protein molecules are distributed on the surface of the fiber and contain natural protein moisturizing factors and a large number of hydrophilic groups, which can quickly absorb human sweat and pass through the grooves. The grooves are quickly introduced into the air and dissipated, so that people's skin is always kept dry, and the anti-pilling and pilling properties reach grade 3-4. Milk silk fabric is the most potential fiber today, and it can be blended with other fabrics, so it can also produce sportswear, casual wear, shirts, high-end ready-to-wear fabrics, etc.
How to identify milk silk fabrics:

First, the combustion identification method:

1. Near the flame: melts and curls.
2. Melting flame: curling, melting, burning.
3. Leaving the flame: burning, sometimes self-extinguishing.
4. Smell when burning: hair burning smell.
5. Residue characteristics: black, basically crunchy, but with a very small amount of hard lumps.

Dissolution identification method:

When the milk protein fiber is heated at a constant temperature of 100 °C for 30 minutes in a 2.5% NaOH solution, the unique phenomenon of milk protein can appear.

State: During the whole process of dissolving, the volume of the fiber expands to a jelly-like shape, and the color will gradually change from the natural color to dark red, and then the dark red will fade to light yellow.
