Comfortableness of T/C fabrics finished with γ-poly glutamic acid

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