Abstract

The invention discloses a noniron finishing method of a silk fabric. The noniron finishing method particularly comprises the following steps: moistening and rinsing the silk fabric with warm water twice, refining and expanding the silk fabric by using a biological enzyme, after rinsing with warm water, padding the expanded silk fabric in a wash and wear finisher containing silk fibroin, citric acid and chitosan quaternary ammonium salt, then predrying the silk fabric, tentering at constant temperature, baking at high temperature, washing with water and drying, and pressing-packaging to obtain the noniron finished silk fabric. According to the noniron finishing method, a biological enzyme technology is combined with a padding technology, the silk fabric is subjected to noniron finishing by using the silk fibroin, the citric acid and the chitosan quaternary ammonium salt, so that the noniron finishing method has the advantages of simple and effective, environmental-friendly and biological effects. The silk fabric prepared by adopting the noniron finishing method reaches a noniron degree, and has a good crease-resisting and deformation-resisting capabilities; the dyeing performance of the fabric is improved; the handfeel, the style and the mechanical property of the fabric are reserved, and thus the noniron finishing method is an ideal noniron finishing method of the silk fabric.

Description

Technical field: [0001] The invention belongs to the technical field of silk products, in particular to a non-ironing finishing method of silk fabrics. Background technique: [0002] In the process of use, the fabric will undergo large deformation or strain after repeated action or long-term friction and expansion, such as shrinkage, arching, wrinkling, bursting, draping, etc. This is because the fabric is connected by friction between fibers and fibers, yarns and yarns, and its mechanical properties are prone to deformation, anisotropy, and nonlinear mechanical properties. [0003] In order to maintain the stable shape and specific mechanical properties of the fabric, physical and chemical methods are often used. The physical method is to adopt a stable fabric structure, optimize the composition of the yarns in the fabric, the interweaving mode and the running direction of the yarns, and use the tenter frame or pre-shrinking machine to control the shrinkage of various fabr...
