Problems solved by technology

The problem of the existing single suede fabric used for sewage treatment is mainly that there are problems in the materials of weft inserting and knitting chain yarns, as well as in weaving and finishing processes, which lead to poor plush effect and insufficient space between knitting chains, which affects its filtration. Effect and service life
[0004] In order to meet the market demand, reduce the cost of filter cloth, and improve the filtering effect and production efficiency, this application adopts cut velvet technology to develop a knitted single suede fabric filter cloth, which solves the shortcomings of low production efficiency and high cost of knitted cut velvet fabric filter cloth

Embodiment 1

[0040] Example 1: A method for manufacturing knitted cut pile fabrics for sewage treatment, using a domestic double-needle bed Raschel warp knitting machine for weaving, then setting the shape, cutting width, and finishing. Proceed as follows:

[0041] (1) Weaving

[0042] Double-width weaving using a commonly used double-needle bed warp knitting machine: the weave structure is a warp knitting structure, and the laying method is the same direction laying yarn, which is woven by closed-end chain knitting; the warp yarn is divided into ground warp and pile warp (see figure 1), the ground warp is knitting chain and weft insertion, the knitting chain uses polyester filament, the weft insertion is composed of polyester filament and high twist polyester yarn; the velvet warp is polyester acrylic yarn or acrylic yarn, and the velvet yarn is hung on the knitting chain, Weaving back and forth between two layers of base fabric to form a fabric; the raw material of the ground warp is 15...

Embodiment 2

[0051] Embodiment 2: As described in Embodiment 1, the difference is:

[0052] The used double needle bed warp knitting machine is made up of 5 combs, and the speed of a machine is 900r / min. The raw material of the ground warp is 150D / 35F polyester filament and twisted 300D / 288F polyester filament in a ratio of 2:1, and the pile warp is 25NM / 2D pre-expanded acrylic yarn.

[0053] The post-finishing process conditions are as follows: dry expansion temperature is 100°C, time is 25 minutes, holding time is 5 minutes; gluing is applied by rolling glue and scraping at the same time, the gluing interval is 5mm, the cloth speed is 14m / min, and the temperature is 130°C; The shearing speed is 15m / min, and the gauge is 13mm; the carding gauge is 2, and the carding depth is 2 / 3 of the carding depth; the second shearing speed is 15m / min, and the gauge is 13mm.

[0054] The performance index of the product is that the pile height is 12mm, the gap between the knitting chain and the knittin...

Abstract

The invention relates to a knitted single-suede fabric for sewage treatment and a manufacturing method thereof. The fabric is knitted by a warp knitting machine, shaped, slitted and post-finished, wherein a weave structure adopted for knitting is a warp knitting structure, yarn laying in the same direction is adopted as a yarn laying mode, and knitting is conducted in a closed chain braiding mode;ground warp is braided chains and lining weft, polyester filaments are used as the braided chains, and the lining weft is composed of polyester filaments and highly-twisted polyester yarn; pile warpis polyester acrylic blended yarn or acrylic yarn; the post-finishing step comprises the procedures of dry expansion, gumming, shearing, combing and secondary shearing, wherein the gumming mode of simultaneously carrying out gum rolling and gum scraping is adopted, and secondary shearing treatment is conducted. The fabric is knitted with double width by using the warp knitting structure, the production efficiency is improved, and the cost is reduced. The plush effect of the suede is good, the strength of the fabric is good, the filtering and decontamination effect is improved, the fabric is firm and durable, and fluffs do not easily fall off.

Description

technical field [0001] The invention relates to a knitted single suede fabric used for sewage treatment and a manufacturing method thereof, belonging to the technical field of textiles. Background technique [0002] The annual sewage discharge in the country is about 35 billion cubic meters, while the centralized treatment rate of urban sewage is only 15%. Other sewage is directly discharged into nearby water bodies without any effective treatment, making rivers and canals that originally functioned as flood discharge and beautifying the landscape become natural sewers. Compared with developed countries, my country's economic level is still relatively backward, and the funds for sewage treatment are still in short supply. It is impossible to completely copy foreign technologies and models. It is difficult to improve the water environment by relying on large-scale construction of urban sewage treatment plants at this stage. . [0003] Using knitted fabrics for sewage treatme...
