Product Description

Refined cotton as ether, ester products, raw materials widely used, known as industrial MSG in the world.

We adopting 100% Xinjiang cotton linters as raw material, alkaline cooking, oxidizing bleaching refined a uniform loose, no wood, bamboo shavings, sand, oil, metals and other impurities on the white floc. The main chemical ingredient is cellulose, lignin and hemicellulose. It is composed of carbon, hydrogen, three kinds of elements, the oxidizing bleaching subtracting refined cooking and refined cotton, has a low impurity content, the higher swelling capacity and response, preferably a polymerization degree and whiteness

Our company refined cotton product features:

1. All raw materials we adopt the Xinjiang and Central Asia's cotton linters , the cotton linters has  high maturity, refined cotton  made by the  cotton linters has  high alpha cellulose content, etherification reaction to reduce polymerization degree in small amplitude.

2  Because of the use of advanced and reasonable production technology, refined cotton whiteness  could reach 87%, the polymerization degree can reach more than 2800, low content of impurities, without other fiber (no three wire.)

3 Our company refined cotton has following series goods:

 M series: M5,M15,M30,M60,M100,M200,M400,M500,M650,M1000

 X series:X15,X30,X60,X100,X200
