Abstract

The invention relates to a production formula of a high-speed chemical fiber godet roller for spinning polyester filaments. The godet roller is formed by bonding and compounding an outer layer of a cylindrical tubular structure and an aluminum bushing of an inner layer; The outer layer of the roller is made of a vulcanized rubber composite material layer, and the raw material components of the vulcanized rubber composite material layer include: carboxylated nitrile rubber, 100 parts; elastomer, 10-20 parts; stearic acid, 1-1.5 parts zinc oxide, 5 parts; titanium dioxide, 5 parts; organic color masterbatch, 0.5 parts; accelerator, 1-2 parts; anti-aging agent, 1.5 parts; aluminum oxide, 10-15 parts; antistatic plasticizer, 5-10 parts; auxiliary cross-linking agent, 1-2 parts; colloidal nano sulfur, 4-5 parts. The high-speed chemical fiber godet roller prepared by the invention obviously prolongs the regrinding cycle of the chemical fiber godet roller, ensures the quality stability of the chemical fiber godet roller during the service period, reduces the difficulty of maintenance of the rubber roller, and improves work efficiency.

Description

technical field

[0001] The present invention relates to the manufacture technical field of textile rubber roller, relate in particular to a kind of production formula of the high-speed chemical fiber godet roller of spinning polyester filament. Background technique

[0002] Polyester is used as a clothing fiber, and its fabric can achieve wrinkle-free and non-ironing effects after washing. Polyester is often blended or interwoven with various fibers, such as cotton polyester, wool polyester, etc., and is widely used in various clothing and decorative materials. Polyester can be used industrially for conveyor belts, tents, canvas, cables, fishing nets, etc., especially polyester cords for tires, which are close to nylon in performance. Polyester can also be used in electrical insulation materials, acid-resistant filter cloths, and pharmaceutical industrial cloths. Synthetic fibers have been widely used in various fields of the national economy because of their high strength...
