湿式加工ライン全体にわたる繊維補助剤
前処理、染色、印刷、仕上げ助剤のプロセスごとのマップと、ZDHC / OEKO-TEX 準拠の角度。
Pretreatment
Desizing agents, scouring agents, wetting/penetrating agents, peroxide stabilisers, chelating dispersants — remove size, oils and impurities for uniform absorbency and whiteness.
Dyeing
Levelling agents, dispersants, sequestrants, fixing agents, reduction-clearing and soaping agents. Reactive dyeing consumes salt/soda; low-temperature soaping agents cut rinse cycles.
Printing
Thickeners (alginate / synthetic), binders, crosslinkers, emulsion pastes. Hand feel vs. fastness in pigment printing is mostly a binder/crosslinker ratio question.
Finishing
Softeners (cationic / silicone / amino silicone), antistatic agents, flame retardants, water & oil repellents (moving from C8 to C6 or fluorine-free), antimicrobial and soil-release finishes.
Compliance
Brands usually require ZDHC MRSL conformance, OEKO-TEX Standard 100 and the absence of APEO, PFOS/PFOA and azo dyes. Always request MRSL statements and third-party test reports.
