我纠正一下上面的说法,根据中方资料,并没有承认有都用到百分之五十以上的腈纶,但是肯定百分之二十以上是有的。英文好的可以看看以下资料。
According to The Textile School, to manufacturer milk fiber, casein and acrylonitrile are grafted together chemically. They dilute alkali and forcing these solutions through a spinneret into a coagulating bath:
A fiber consisting of a copolymer of casein protein (25%-60%) grafted with 40%-75% acrylic monomers, of which at least half is acrylonitrile, has been developed in Japan under the tradename Chinon. The casein dissolved in aqueous zinc chloride and grafted with acrylonitrile is wet or dry spun into fibers. It dyes readily with acid dyes, but basic and reactive dyes can be used also. The fiber is marketed as a substitute for silk.
