Abstract

The invention provides a preparation method of a modified polyester-nylon fabric. The preparation method comprises the following steps of S1, preparing chitosan with low molecular weight; S2, carryingout plasma pretreatment on a polyester-nylon composite fabric; S3, adding the low-molecular-weight chitosan prepared in the step S1 into a glacial acetic acid solution with a certain temperature, dissolving the chitosan, and keeping the temperature unchanged to obtain a constant-temperature chitosan finishing solution; S4, carrying out high-temperature heating on the pretreated polyester-nylon composite fabric, immersing the fabric into the constant-temperature chitosan finishing solution under the condition that the fabric is not cooled, reacting for a period of time, taking out the fabric,mangling the fabric, immersing the fabric into the finishing solution, reacting for a period of time, taking out the fabric, and airing the fabric for later use; and S5, treating the fabric prepared in the step S4 with snail slime freeze-dried powder to obtain the modified polyester-nylon fabric. According to the invention, snail slime is adopted for finishing, and the novel soft and moisture-permeable fabric is obtained.

Description

technical field [0001] The invention relates to the field of functional fabrics, in particular to a preparation method of modified polyester nylon fabrics. Background technique [0002] Due to the excellent physical and chemical properties of polyester fiber, it is widely used in the textile industry and some other industries. However, its smooth surface and no hydrophilic groups on the macromolecular chains lead to poor antistatic, hydrophilic and wearable properties of polyester fibers. Improving the hydrophilicity of polyester fiber is the main way to improve its antistatic performance and wearing performance. Alkali reduction can not only greatly improve the hydrophilic properties of polyester fibers, but also increase the softness and drapability of fibers, but a large amount of alkali will cause serious pollution to the environment. [0003] There are many methods to improve the hydrophilicity of polyester fibers, including physical modification and chemical modifica...
