Washable high-content collagen polyester coated fabric and preparation method thereof

The invention discloses a preparation method of a washable high-collagen-content terylene coated fabric, and belongs to the field of textile after-finishing, the method adopts didodecyl dimethyl ammonium bromide to carry out cation modification on terylene in advance, so that the adsorption capacity of collagen on the terylene is improved, and the adsorption capacity of the collagen on the terylene is improved; and carrying out padding coating on the polyester fabric by adopting a novel collagen coating finishing agent to finally obtain the washing-resistant hydrophilic polyester coated fabric with high collagen content. According to the method, the collagen content and washing resistance of the surface of the polyester fabric can be improved while better wearability is achieved. 本发明公开了一种耐洗涤的高胶原蛋白含量涤纶涂层织物的制备方法，属于纺织品后整理领域，该方法预先采用双十二烷基二甲基溴化铵对涤纶进行阳离子改性，提升胶原蛋白在涤纶上的吸附量，之后采用新型胶原蛋白涂层整理剂对涤纶织物进行浸轧涂层，最终获得耐洗涤的高胶原蛋白含量的亲水性涤纶涂层织物。该方法能够在达到较好服用性能的同时，提升涤纶织物表面的胶原蛋白含量以及耐洗涤性能。
