Process for producing polyester fiber blanket

Abstract

The process of producing polyester fiber blanket includes the following steps: sortig cationic DTY yarn; and warp knitting or weft knitting. The present invention has the advantages of no need of re-networking step to simplify the technological process, the universality of DTY yarn on both warp knitting loom and weft knitting loom, blotch warp knitting, less deformation of the blanket, and blanket fluff height of 4.0-12 mm, unit area weight of 280-550 g / sq m.

Description

Technical field [0001] The invention belongs to the technical field of polyester fiber blanket processing, and specifically relates to a production process of a polyester fiber blanket. Background technique [0002] The production process of polyester microfiber blankets is processed by warp knitting machines as an example. The steps involved are well known in the industry. The specific steps are: material selection (preparation of DTY silk raw materials), warping, weaving (warp knitting), Splitting, dyeing or printing, loosening, fixing, finishing, heat setting, back raising finishing, sewing, and blanket formation. In view of the fact that all-polyester (also known as pure polyester) microfiber has a lint-like texture, it is widely used to process clothing, toys, shoes, hats, composite floor mats, quilted mats, bedding, etc.; and in view of pure polyester Microfiber blankets have good warmth retention, so they have gradually replaced cotton-type products and acrylic products in...

Problems solved by technology

However, further research by the applicant shows that the technical solution of the above-mentioned patent application still has the following deficiencies. One is that the secondary network will affect the uniformity of the linear density, thereby bringing a certain impact on the stability of the carpet surface; the other is, Due to the increase in the number of network points after the secondary network, the resistance increases in the process of brushing after finishing, and the number of fluffing on the reverse side increases at the same time; the third is that in the warp knitting process, the weaving process used is the warp knitting half-through process, and the width of the door is stable. The stability is difficult to control, which eventually leads to unsatisfactory stability of the finished product and weak resistance to deformation; fourth, due to the need for re-network, the process is lengthy
