Abstract:

In order to solve the problems of poor moisture absorption and breathability of polyester fabric with poor antistatic properties, keratin-coated polyester fabric was obtained by coating different mass fraction of wool keratin solutions on chemically eroded polyester fabric. Subsequently, the structure and morphology of the fabric before and after finishing were characterized by using transform infrared spectrometry and scanning electron microscopy electrom microscopy. In addition, breathability, breathability, mechanical properties, antistatic properties, washable properties and drapability were studied. The results show that breathability rate of the chemically eroded polyester fabrics is increased by 57.7%. After keratin coating, the moisture regain ratio of the fabrics is increased by 3.3 times, and breaking strength and elongation of the fabrics are slightly reduced. Moreover, the drapability of the treated fabrics is deteriorated, and the static drape is better than the dynamic drape. The static voltage peak and static voltage decay time of treated fabrics are almost zero, and the antistatic property of the fabrics is obviously improved. As a garment cloth, the polyester fabric treated with a keratin solution of a mass fraction of 20% is relatively soft and comfortable, and the mass increase ratio after coating rraches 9.7%.
