China Fabric Color Absorber Market: Manufacturers & Suppliers

Color catcher sheets are manufactured using an absorbent spunlace substrate that undergoes functional cationic modification. During a wash cycle, garments release excess unfixed dyes (predominantly direct and acid dyes) carrying negative anionic surface charges into the wash liquor. The quaternary ammonium groups chemically grafted onto our cellulose/viscose nonwoven matrix possess strong positive cationic charges. This triggers rapid electrostatic attraction, locking the dyestuff molecules irreversibly onto the sheet via strong covalent and hydrogen bonds, preventing redeposition onto lighter garments.

The standard basis weight ranges from 45 GSM to 75 GSM for household retail applications, and up to 100–120 GSM for heavy-duty commercial laundry applications. The most proven fiber blend is 100% Viscose or a Viscose/Polyester blend (such as 70/30 or 50/50). Viscose provides optimal chemical absorption sites and hydrophilic wetting speed, while polyester maintains critical wet tensile strength under vigorous washing agitation. We also manufacture 100% biodegradable sheets utilizing pure bamboo, cotton, or certified PLA fibers.

Yes. As a primary manufacturer, YDL Nonwovens supplies master rolls slit precisely to customer requirements. Our rolls feature uniform tension winding, minimal splice frequency, core diameters of 3 inches (76 mm) or customized sizes, and widths tailored for high-speed automated folding, perforating, and carton-packing lines.

Our functional finishing process employs heat-cured crosslinking agents that permanently bind the cationic polymer chains directly onto the fiber matrix. Rigorous laboratory desorption testing (including boiling water wash-out tests) confirms zero chemical migration or leaching into the wash liquor, ensuring full compliance with OEKO-TEX Standard 100 and REACH requirements.

Conventional spunlace fabric relies entirely on physical pore filtration and capillary absorption; it lacks surface charge affinity and cannot prevent fugitive dyes from desorbing back into the wash liquor. In contrast, functional color absorber nonwovens undergo secondary surface chemistry treatments that introduce active cationic dye-trapping sites, turning passive filtration into an irreversible chemical-capture mechanism.

For standard roll goods, our typical MOQ is 1,000 kg per specification. Custom basis weights, specific fiber blends, or specialty functional finishes usually require an MOQ of 3,000 kg to ensure optimal hydroentanglement line balancing. Lead times generally range from 15 to 25 business days from final specification confirmation to container loading at our Changshu mill.
