6, the textiles industry
Specs indicators ＩＨ７ ＩＭ７ Textile Industrial CMC, CMC substituting machinery Sizing enable a smooth surface, wear soft Loom increased production capacity. Sizing with CMC texture of cotton yarn and light, non-perishable moldy facilitate preservation, as CMC Sizing lower rate than food, Therefore, in dyeing cotton without the desizing.
