MILK FIBER

摘要

Invented in Italy in the 1930s, the process for manufacturing milk fiber is similar to the lyocell process for producing viscose rayon from plant pulp.The fiber is made from dairy milk, and it takes about 12 gallons of milk to make a pound of fiber. Because the casein (milk protein) is extracted from dehydrated milk solids, mills can use waste milk that is spoiled or contaminated and not fit for consumption.The milk is first dewatered, and the casein is dissolved in an alkali solution. The solution is extruded through a very fine spinneret into a bath that neutralizes the alkali and blends the casein with acrylonitrile to produce the strong, fine fibers that can be spun into thread or yarn. The process has been certified green under the Oeko-Tex Standard 100 for international textiles, meaning that the manufacturing process and the resulting fibers are environmentally benign and not harmful to wearers. It is machine washable, so it's great for baby blankets, baby clothes, and light summer wear.The fabrics breathe well and wick moisture. In knitting, the yarn has no memory,' so fabrics may grow a bit, but this isn't ' usually an issue for weavers.
