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, leading to the agglomeration of inorganic nanopowders in the pre-aggregation process
[0008] In summary, the existing technologies mainly rely on the huge specific surface area of ​​inorganic nano-powders to diffusely scatter ultraviolet rays to produce an anti-ultraviolet effect, and the stability and efficiency of the anti-ultraviolet effect need to be improved. Starting from the mechanism, the preparation of polyester with better anti-ultraviolet effect and good spinnability

Embodiment 1

[0034] This embodiment provides a method for preparing an anti-ultraviolet, anti-static, anti-pilling polyester chip, which includes the following steps:

[0035] (1), primary esterification reaction section: take 18kg of purified terephthalic acid (PTA), 7.5kg of ethylene glycol (EG) and add 70 liters of polyester experimental equipment, after stirring evenly, start to heat up and pressurize to 0.3Mpa, Esterification is carried out, and the esterification temperature is controlled at 250-265°C. After the esterification is completed, the water is discharged, and the normal pressure is returned to complete the reaction.

[0036] (2) Secondary esterification reaction section: After the primary esterification is completed, ethylene glycol is first added to lower the temperature of the reactor to 230-235°C, and then 450g of polyethylene glycol with a number average molecular weight of 2500 that has been heated and melted is added The diol was added into the reactor under the prote...

Abstract

The invention relates to a preparation method of an anti-ultraviolet, antistatic, and anti-pilling polyester chip, which comprises an esterification reaction procedure and a polymerization reaction procedure; the esterification reaction procedure comprises a primary esterification reaction phase and a secondary esterification reaction phase, and flexible polyethylene glycol is introduced into thesecondary esterification reaction phase as a third monomer; after the esterification is completed, a hindered amine light stabilizer and a hindered phenol antioxidant, which are respectively blended with solvents of acetic acid and glycol, as well as hydroxyl silicone oil are added; after the prepolymerization of the polymerization reaction procedure is finished and before the final polymerization, an ultraviolet absorbent and an antistatic agent are added. Polyester fibers spun by the polyester chip obtained by the method of the invention have excellent anti-ultraviolet, antistatic, and anti-pilling effect; when the polyester fibers are woven into knitted fabrics and woven fabrics, related technical indexes obtained by testing are that: the ultraviolet transmittance is not more than 5.0%; the anti-pilling performance is not less than grade 4; and the fiber volume specific resistance is not more than 10*1010 omega.cm.

Description

technical field [0001] The invention relates to a preparation method of anti-ultraviolet, anti-static and anti-pilling polyester chips. 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, but they are easy to wrink...
