Problems solved by technology

[0002] At present, similar T-shaped mesh fabrics on the market are generally low-stretch products, with surface deformation, serious warp and weft bending, and poor processability in the downstream.
Our company used to weave ordinary polyester filament as the raw material, which has a large shrinkage rate and low strength. The main raw material resin for shaping is also ordinary resin (melamine). It is easy to tear; due to the large shrinkage rate of polyester filament and the loose shape, the weft of the cloth surface is seriously skewed and the cloth surface is loose

Embodiment 1

[0013] Embodiment one: the process of producing T-shaped cloth or large mesh cloth base cloth

[0014] First of all, the raw materials have passed the inspection and are put into the warehouse. The raw material warehouse requires drying, ventilation, and humidity less than or equal to 80%. The raw material is polyester filament. The strength is greater than or equal to 3.8cN / dtex, the coefficient of variation of the breaking strength is less than or equal to 5.0%, the elongation at break is 24% to 32%, the coefficient of variation of the elongation at break is less than or equal to 12.0%, and the degree of network is 2 to 12 per meter. The boiling water shrinkage rate is 6% to 8%, and the oil content is 0.3% to 1.3%.

[0015] Followed by warping, the warping workshop requires constant temperature and humidity. Silk plate porcelain eye, yarn dividing needle, tension roller, wool meter, yarn dividing needle, storage yarn dividing needle, oiler, herringbone reed dividing needle,...

Embodiment 2

[0019] Embodiment two: the technique of producing green mesh cloth or small mesh cloth:

[0020] This embodiment is all the same as Embodiment 1 in material selection, warping and weaving process, just add specific dyestuff when finalizing and squeegeeing, preheating setting machine oven, batching according to technological requirement: resin, catalyst, dyestuff A, Dye B, dye ℃, degreaser and water are mixed and stirred according to a specific ratio, and put into the slurry tank after stirring evenly. While preparing the slurry, place the base fabric that needs to be shaped on the unwinding machine, install the winding paper tube at the winding place, and guide the base fabric to the slurry slot with the pre-prepared guide cloth. After the oven temperature reaches the specified requirements, Start production, the base fabric passes through the slurry tank for sizing, and then passes through the roller with an air pressure of 0.5KG. During the process of unwinding and sizing, t...

Abstract

The invention discloses a technology for manufacturing T-shaped mesh fabrics, which comprises the procedures of sorting, warping, and fabric manufacture. The technology also comprises the procedures of: weaving and shaping the sorted yarn under a constant temperature and a constant humidity condition; starching by using sizing mixture of resin, accelerant, deoiling agent and water, the content of the resin, accelerant, deoiling agent and water being respectively 8%, 2%, 1% and 89%, the appearance of the accelerant being colourless transparent liquid, and the pH value being 7.0-8.0, the appearance of the sizing mixture of the resin, accelerant, deoiling agent and water being colourless transparent liquid, the pH value is 8-10, and the solid content being 75%-85%; executing the drying procedure in an oven, the oven comprising a preheating section, a sizing section and a cooling section, a sizing base cloth passing the oven in a constant speed; draw-off and shaping; rolling and warehousing. After the technology is adopted, the manufactured T-shaped mesh fabric has high intensity, little longitude and latitude shrinkage, good verticality, even and well-pressed cloth cover, stable style, and easier rolling; and the warp winding can be up to 1.5 meter, thus being beneficial to transportation and improving manufacturing efficiency.

Description

technical field [0001] The invention relates to a polyester fabric processing technology, in particular to a polyester fabric production and processing technology. Background technique [0002] At present, similar T-shaped mesh fabrics on the market are generally low elastic yarn products, with surface deformation, serious warp and weft bending, and poor processability in the downstream. Our company used to weave ordinary polyester filament as the raw material, which has a large shrinkage rate and low strength. The main raw material resin for shaping is also ordinary resin (melamine). It is easy to tear; due to the large shrinkage rate of polyester filament and the loose shape, the weft of the cloth surface is seriously skewed and the cloth surface is loose. Contents of the invention [0003] The object of the present invention is to provide a production process of T-shaped mesh cloth with stable style and crisp cloth surface. [0004] In order to achieve the above objec...
