SPF fiber, soybean protein fiber

SPF fiber, soybean protein fiber is made from soybean cake after oiling, by bioengineering hi-tech, synthesizing from the distilled spherical protein.

The fiber has the softness of cashmere, the luster of silk, and perfect ventilation.

Regular spec.: 1.5DX38MM/51MM, natural or bleached

Package: 200kg/pressed bale ( L1300mm x W900mm x H600mm )

SPF fiber, soybean protein fiber filled up the vacancy in textile material development of our country as a big textile-producing country. It will inevitably stimulate the new product development in the field of cotton, wool and spun silk spinning, and bring the textile corporations new development opportunity.
