Problems solved by technology

[0003] In the preparation process of conventional warp-knitted plain single-layer blankets, the white gray cloth is printed and dyed after ironing and cutting. The printing and dyeing of the prior art mostly adopts flat screen printing and dyeing, tie-dyeing and cylinder dyeing, which are affected by the weight and thickness of the blanket and the height of the suede surface. The flat screen printing commonly used in the prior art has the following disadvantages: Poor front printing penetration, prone to fluff and white hair on the reverse side, conventional one-time printing process on the front of such products, there is a problem of screen seams, and the cloth falls on the hanging cloth after printing and dyeing On the car, it is easy to produce hanging cloth rod marks, and steaming in the high-pressure tank is also easy to produce water drop marks, and the length of one-time production is limited; while dyeing with a pad dyeing machine is prone to uneven coloring and serious problems of unevenness. Dyeing is also limited by the weight of the blanket, that is, the conventional printing and dyeing process of the prior art cannot produce plain single-layer blankets with high weight and high quality, which seriously restricts the development and progress of the industry

Embodiment 1

[0046] A method for preparing a rotary screen plain high-gram-weight single-layer fleece blanket, comprising the following steps:

[0047] Step 1: Raw material selection

[0048] Choose Dayou polyester, the veil is low elastic yarn with a fineness / composite number of 250D / 120F, and a fiber density of 2.08D. , bottom yarn 22%;

[0049] Step 2: Weaving and cutting

[0050] 2.1 Weaving: Use a double-needle bed warp knitting machine with a gauge of 16mm to weave the gray fabric, the needle distance is 14 needles / inch, the thread threading method is full threading, and the base fabric adopts the method of four-needle weft insertion and chain knitting;

Abstract

The invention relates to a preparation method of a rotary-screen plain-colored high-gram-weight single-layer raising blanket. Suitable raw materials are selected and woven to obtain a grey cloth, thenslitting and pre-shaping are conducted, and pre-treatment is conducted; in the pre-treatment process, after the grey cloth is subjected to pre-drying, brushing, luster finishing and hot shearing, printing and dyeing parameters are adjusted according to the fact that the net gram weight of the product is high, rotary screen printing and dyeing equipment is adopted, an empty rotary net is utilizedas a color paste adding net and a permeation net, a permeation device is additionally arranged for printing and dyeing, the printing and dyeing effect is ensured, a drying and steaming integrated machine is adopted for color fixation, the color fixation effect is ensured, and the efficiency is improved; then the front and reverse sides of a semi-finished single-layer blanket are sequentially subjected to brushing, luster finishing, hot shearing, reverse side raising, brushing, and hot shearing again, and then cloth cutting and edge covering are conducted to obtain the finished product. The preparation method is reasonable in process and high in efficiency, and has the good printing and dyeing effect and high production and application value.

Description

technical field [0001] The invention relates to the fields of textile technology and printing and dyeing technology, in particular to a method for preparing a rotary-screen plain-color high-gram-weight plain-color single-layer raised blanket. Background technique [0002] The blanket is made of warp knitting machine using polyester low-elasticity yarn as the face yarn to weave the gray cloth. After the gray cloth is cut by a cutting machine, it is puffed and shrunk by a high-temperature setting machine, and then it is brushed, ironed, printed, steamed, washed, and dried. , Finishing, edge wrapping and other processes, it is widely welcomed because of its practical effects such as aesthetics and warmth. , a single piece of double-sided fleece blanket made by pulling part of the front plush from the reverse side. This kind of blanket has the same color on the front and back. [0003] In the preparation process of conventional warp-knitted plain single-layer blankets, the whit...
