Embodiment Construction

[0028] For the generation of ultraviolet rays in this method, ultraviolet generating devices such as low-pressure mercury lamps, deuterium lamps, xenon lamps, and lasers can be used.

[0029] (1) Modification of the surface of polyester weft plain knitted fabric by ultraviolet irradiation technology

[0030] 1. Use the usual washing method to remove the attachments on the surface of the weft knitted fabric woven from polyester filaments. The low-pressure mercury lamp is in the air at room temperature, the irradiation distance is 40mm, 10 minutes (the irradiation amount is 10.2J / cm 2 ) irradiates three pieces of weft jersey fabric from the weft jersey fabric.

[0031] After the irradiation, the fabric was dipped in 1% acetic acid to adjust the chitosan with a deacetylation degree of 85% to pH=3, and the concentration was 0.5vol.% Chitosan aqueous solution (25 ℃) for 10 minutes, and then Use rolls to squeeze liquid, after making the squeezed liquid rate 40%, make it dry with 50 ...

Abstract

A method is doing character-change on macromolecule-fibre materials. It is no need to use water to be the medium, no need chemical, steam. This method omits the drying course, the disposal of liquid waste. The cost of equipment is low, it is operative. It save the energy, is high efficiency, no pollution, fast, economize resource, be propitious to protect environment. The approach of character-change is: (a) use usual baptize method to eliminate the appendiculate things. (b) put the macromolecule-fibre materials in the oxo gas, irradiate it for 5-30 minutes. (c) dip the macromolecule-fibre materials in the shell polysaccharide liquid with the chemical ability of deacetamide over 80%, the chroma is 0.3-0.7 vol% for 5-15 minutes. (d) after shell polysaccharide is on the face of the macromolecule-fibre materials, use roller fluid, let the roller rateis 40-70%. (e) dry it by the hot wind of 50-110 deg.C, let the shell polysaccharide is on the face of the macromolecule-fibre materials.

Description

technical field [0001] The invention relates to a method for modifying the surface of a polymer fiber material, in particular to a method for modifying the surface of a polymer fiber material by ultraviolet irradiation technology. Background technique [0002] At present, the surface modification technologies of fiber materials mainly include: alkali washing, strong oxidant oxidation swelling, plasma and other methods. [0003] Alkali washing is a typical and effective method for surface treatment of polyester fibers, and it is called alkali weight reduction in industry. The basic principle of the alkali reduction method is the saponification reaction. During the saponification reaction, OH - First attack -(C)(-O)-O-R with δ + The charged C atom forms an adduct, and then the ester bond is hydrolyzed and broken, and the macromolecule is degraded into a molecule with a smaller molecular weight. The reaction continues in sequence until sodium tere...
