Specifications
Our company refined cotton product features:
1. All raw materials we adopt the Xinjiang and Central Asia's cotton linters , thecotton 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%, thepolymerization degreecan reach more than 2800, low content of impurities, without other fiber (no three wire.)
3 Our company refined cotton has following series goods:
Mseries: M5, M15, M30, M60, M100, M200, M400, M500, M650, M1000
X series: X15, X30, X60, X100, X200
