Production formula of spinning rubber roll for chemical fiber double core-spun yarn

Abstract

The invention relates to a production formula of a spinning rubber roll for a chemical fiber double core-spun yarn. The spinning rubber roll is formed by bonding and compounding of the outer aluminumbushing and inner aluminum bushing of a cylindrical tubular structure. The outer layer is prepared from a vulcanized rubber composite material, which comprises the following components by weight: 100parts of carboxyl nitrile rubber; 10-20 parts of tetrafluoroethylene ultrafine micropowder; 1-1.5 parts of stearic acid; 5 parts of zinc oxide; 5 parts of titanium dioxide; 0.5 part of organic color masterbatch; 1-2 parts of a promoter; 1-1.5 parts of a methacrylamido reactive anti-aging agent; 1-1.5 parts of an anti-aging agent AW; 1-3 parts of microcrystalline paraffin; 8 parts of fumed silica;10 parts of an antistatic plasticizer; and 4-6 parts of colloidal nano-sulfur. In modern high efficiency spinning process, the spinning rubber roll prepared according to the invention has the wear resistance improved by about 2 times and a damage consumption rate reduced by 80% or above, and the service life of the spinning rubber roll is prolonged.

Description

technical field [0001] The invention relates to the technical field of manufacturing textile cots, in particular to a production formula for spinning cots for chemical fiber double-core core-spun yarns. Background technique [0002] Double-core core-spun yarn is a yarn made of staple fiber as the outsourcing raw material, and two kinds of filaments with different characteristics as the core yarn, which are twisted and spun. Due to the different properties of the two core filaments, a strong complementarity is produced, which makes the yarn have more superior characteristics. Such as cotton bale T400+spandex: T400 (polyester filament) is characterized by good expansion, excellent elastic recovery, better dimensional stability and better strength than spandex. Spandex is characterized by high elasticity and can withstand repeated stretching. Using these two kinds of filaments as the core yarn, the yarn produced by outsourcing cotton fiber not only maintains the good hygrosco...

Problems solved by technology

[0004] On the basis of the existing technology, the purpose of the present invention is to solve the problem that the spinning cots of the chemical fiber double-core core-spun yarn in the prior art spin the chemical fiber double-core core-spun yarn under the condition of modern high-efficiency spinning technology, which is easy to appear. Early oily wear and grooves on the surface, sticking "patterned clothes", resulting in unstable pre-drawing tension and other adverse phenomena, providing a production formula for spinning cots for double-core core-spun yarns for chemical fibers
