Abstract

The invention relates to the technical field of metallized functional textiles, in particular to a pretreatment method for conductive cotton fibers, conductive cotton fibers and a preparation method thereof. The invention discloses a pretreatment method for conductive cotton fibers, which comprises the following steps: adsorbing a modifying agent on the cotton fibers to obtain modified cotton fibers; the modifying agent is selected from plant polyphenols. This pretreatment method uses a green and environmentally friendly modifier, which can be adsorbed on the surface of cotton fibers through hydrogen bonding to form a layer of supramolecular structure film, which can be used as an interface layer between the metal coating and cotton fibers, which can improve The combination of the metal coating and the cotton fiber will not cause any damage to the properties of the cotton fiber, which overcomes the shortcomings of the traditional pretreatment method that will cause fiber damage to the cotton fiber, resulting in deterioration of fiber performance and environmental pollution. The pretreatment method is simple, easy to control, and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of metallized functional textiles, in particular to a pretreatment method for conductive cotton fibers, conductive cotton fibers and a preparation method thereof. Background technique [0002] With the rapid development of modern textile science and technology, people's demand for functional textiles is increasing. People are no longer satisfied with the simple wearing requirements of textile fabrics. In addition to the physical and mechanical properties that general textiles should have, they should also have some special Functional requirements. Metallized functional textiles not only have the functions of conductivity and electromagnetic shielding, but also have the characteristics of fabrics such as softness, breathability, folding resistance, sewing and cutting, etc., and have been extensively studied by scholars at home and abroad. With the continuous advancement of science and technology, conductive ...
