Problems solved by technology

However, compared with various natural fibers, there are still many shortcomings: hard hand feeling, poor hygroscopicity, poor UV resistance, easy to generate static electricity, easy to pilling, difficult to dye, etc.
The disadvantage of this method is: benzotriazole is an organic phenolic compound, which exists as a protonic acid under high temperature conditions, which can destroy the inorganic nano-powder TiO 2 and Al 2 o 3 or SiO 2 Surface organic treatment agent, le

Abstract

The invention relates to a preparation method for a polyester fiber with a composite ultraviolet, static electricity and pilling resisting function. The preparation method comprises an esterification reaction procedure, a polymerization reaction procedure and a spinning procedure. The esterification reaction procedure comprises a primary esterification reaction stage and a secondary esterification reaction stage, flexible polyethylene glycol is introduced as a third monomer in the secondary esterification reaction stage, and after esterification is finished, a hindered amine light stabilizer,a hindered phenol anti-oxidant and hydroxyl silicone oil are added, wherein the hindered amine light stabilizer and the hindered phenol anti-oxidant are prepared by taking an acetic acid and ethyleneglycol as solvents. In the polymerization reaction procedure, after prepolymerization and before final polymerization, an ultraviolet absorbent and an antistatic agent are added. Before the spinning procedure, polyester is sliced for pre-crystallization and drying. The polyester fiber obtained by the method has the outstanding ultraviolet, static electricity and pilling resisting functions, and after being woven into knitted machine-made fabrics, is tested to have related technical indexes comprising the ultraviolet light transmittance of less than or equal to 5.0%, the pilling resistance of more than or equal to level 4 and the fiber volume specific resistance of less than or equal to 10*10<10> ohm.cm.

Description

technical field [0001] The invention relates to a preparation method of polyester fiber with composite functions of anti-ultraviolet, anti-static and anti-pilling. Background technique [0002] Since the advent of polyester fiber, it has been widely used in clothing textiles due to its good strength, excellent wrinkle resistance, drape performance and washable wearability. After decades of rapid development, PET polyester fiber has become the world's most It is the synthetic polyester variety with the largest output and widest application range. However, compared with various natural fibers, there are still many shortcomings: hard hand feeling, poor hygroscopicity, poor UV resistance, easy to generate static electricity, easy to pilling, difficult to dye, etc. Although natural fibers such as cotton, silk, wool, hemp, etc. have good dyeing performance, the fabric has air permeability, good sweat absorption and moisturizing performance, no static electricity, and good comfort...
