Problems solved by technology

However, this is an emerging material, which is expensive and has relatively few end-product development applications
In the previous samples, it was found that pure polyimide fabrics have serious weft skew and unstable shrinkage, which can be improved by interweaving with polyester, but it affects the flame retardancy

Embodiment 1

[0022] A polyimide weft-knitted double-faced fleece protective fabric, made of 32S polyimide spun yarn and 100D / 48 flame-retardant polyester low-stretch yarn, woven on a terry machine, washed with high temperature, softened and dehydrated , drying, napping, combing, scalding, trimming, shaking and shaping, the 32S polyimide spun yarn wraps the 100D / 48 flame-retardant polyester low-elastic yarn in the middle.

[0023] Further, the full-wrapped towel machine has a sinker height of 1.8 mm, a needle pitch of 19 needles / inch, and a barrel diameter of 30 inches.

[0024] A production method of a polyimide weft-knitted double-sided raised fleece protective fabric, comprising the steps of:

[0025] 1) High-temperature water washing: put the gray cloth produced in normal temperature water, add 1.5g / L degreasing agent, the bath ratio is 1:10, raise the temperature to 110°C at a heating rate of 2°C / min, keep the temperature for 20min, and then heat it at 3°C Cool down at a cooling rate ...

Abstract

The invention discloses a polyimide weft-knitted double-faced velvet protective fabric and a production process thereof. 32S polyimide staple fiber yarns and 100D / 48 flame retardant polyester low elastic yarns are knitted on a terry-looping machine and treated by the steps of high-temperature water washing, lustering, dehydrating, drying, galling, combing and cutting, ironing, trimming, fleecing and shaping; and the 32S polyimide staple fiber yarns cover the 100D / 48 flame retardant polyester low elastic yarns. The polyimide weft-knitted double-faced velvet protective fabric has the advantages of good flame retardant property, good warm-keeping property, radiation resistance, acid and alkali resistance, corrosion resistance, bacterium resistance, good strong force, good firmness, soft hand feeling, bright luster, fluffiness and fleecing, good anti-galling and anti-balling-up properties and stable cloth surface the shrinkage rate is smaller than 5% and the weft bias is smaller than 3%; and the flame retardant damaged length of the cloth surface reaches 1.6 cm and the effect is good.

Description

technical field [0001] The invention belongs to the application field of high-tech fiber terminal products, and in particular relates to a polyimide weft-knitted double-faced fleece protective fabric and a production process thereof. Background technique [0002] One of the key points emphasized by my country's textile technology development strategy is to break through the key technologies of high-performance fiber preparation and application. Polyimide is a high-performance fiber material with excellent thermal insulation performance, high temperature resistance, acid and alkali resistance, oxidation resistance, radiation resistance, natural antibacterial, good color fastness, good anti-pilling and so on. However, this is an emerging material, which is expensive and has relatively few end-product development applications. In the previous samples, it was found that pure polyimide fabrics have serious weft skew and unstable shrinkage, which can be improved by interweaving w...
