6, the textiles industry

Specs indicators			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.
