Method for modifying high-polymer fibre material surface

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...

Problems solved by technology

However, in the plasma modification, it is required to be carried out under vacuum conditions, the equipment requirements are high, the price is expensive, it is not suitable for industrial production, and there are also problems that it is difficult to control the degree of fiber surface modification.
