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

Embodiment 1

[0018] according to figure 1 The steps shown are first to select materials, namely to purchase single-strand 300D / 96F cationic DTY yarn from the market, and then put it into weaving, specifically through the up and down of the 26-inch 14-needle or 30-inch 14-needle weft knitting machine. Arrange the triangles and follow the six process cycles as follows:

[0019] ①The wool yarn (DTY) is fed from top to bottom, with a triangular arrangement bottom 1+1 bottom 

[0020] ②Bottom wire (FDY) knitting bottom layer, triangular arrangement bottom  high 

[0021] ③Cut circle, triangle arrangement high  bottom 

[0022] ④The wool yarn (DTY) is fed from bottom to top, and the bottom of the triangle arrangement is 1+1 high.

[0023] ⑤Bottom wire (FDY) knitting bottom layer, triangular arrangement bottom  high 

[0024] ⑥Cut circle, triangle arrangement bottom  high 

[0025] The circular knitting needles above are under the fixed triangle. On the one hand, they make a circular motio...

Embodiment 2

[0027] Select 250D / 96F cationic DTY yarn, and the rest is the same as in Example 1. The pile height of the obtained blanket is 5-7mm, and the weight is 320-380 g / m 2 .

Embodiment 3

[0029] Use 200D / 96F cationic DTY yarn, and the rest is the same as in Example 1. The blanket has a pile height of 8-10mm and a weight of 380-480 g / m 2 .

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...
