Abstract

The invention discloses a cotton fabric hydrophobic finishing method based on acetic anhydride-acrylic ester-electron beam technology, belonging to the field of functional textiles. The method of the invention first adopts acetic anhydride to esterify cotton fibers, and then uses electron beams to treat cotton fabrics with acrylic ester reagents dissolved in alcohol solvents to obtain textiles with hydrophobic properties. Compared with alkanes and olefins solvents, the alcohol solvent used in the method of the present invention has the advantages of low toxicity, small irritation, and low cost. The method of the present invention can avoid environmental problems caused by perfluorinated hydrophobic additives, and electron beam irradiation can chemically combine fiber macromolecules and functional macromolecules, and the obtained product has good uniformity, repeatability, and low cost, and has no effect on fabrics. The damage is small, and this method can be used for the hydrophobic functional finishing of cotton fabrics.

Description

technical field

[0001] The invention relates to a cotton fabric hydrophobic finishing method based on acetic anhydride-acrylic ester-electron beam technology, belonging to the field of functional textiles. Background technique

[0002] Hydrophobic materials have been paid more and more attention to in people's daily life and industrial production. For example: medical staff clothing, self-cleaning, high-end clothing, outdoor clothing, etc., hydrophobic materials have played an important role. There are a lot of hydrophilic groups in the cotton fiber structure, and the porous structure with more voids makes it easy to be polluted by various polluting liquids. Therefore, the research and preparation of cotton fabrics with hydrophobic properties has certain use value and immeasurable value. economic significance.

[0003] The hydroxyl groups on the chemical structure of cotton fibers are chemically active and can react with hydrophobic reagents to prepare hydrophobic products...
