Abstract: To enhance the wearing comfortableness of T/C fabrics, the finishing process of γ-PGA (γ-Poly glutamic acid) on T/C fabrics was studied. The effects of concentration of γ-PGA and curing temperature on hygroscopicity, static-resistance and permeability of T/C fabrics were investigated. The optimal finishing process of γ-PGA on T/C fabrics was established, and the influence of washing times on the finishing effect and handle was tested. The result revealed that the hygroscopicity, static-resistance and permeability of T/C fabrics enhanced as the mass percent of γ-PGA increased, however, the curing temperature had little effect on the comfort of fabrics. The optimal comfortability could be obtained by finishing with γ-PGA 1.0%(mass percent )and curing at 110-120℃ for 3minutes. After finishing, and the T/C fabrics can retain the antistatic property up to 20 washing times.
