A kind of preparation method of burnt-out polyester six-grid cloth

Abstract

The invention provides a method for preparing burnt-out polyester six-grid cloth, which belongs to the technical field of textiles. Preparation of burnt-out alkaline slurry: according to mass percentage, mix 1.5-2.5% of alkaline burnt-out paste, 6-8% sodium hydroxide powder, and 89.5-92.5% of water to prepare burnt-out alkaline slurry, control The slurry viscosity of burnt-out alkaline slurry is within 300Mpa.S; burnt-out: through the bubbling feeding mechanism, the cloth traction speed is controlled within 5 m / min; steaming and washing process: burnt-out sizing and drying The temperature is 125°C, the vehicle speed is 20 m / min, and after the steaming temperature is 115°C, it needs to be washed by open-width and rope-mounted washing machines at room temperature; The fluff with alkaline is preliminarily cleaned, and then the residue on the bottom plate is thoroughly washed by an 8-slot rope-shaped continuous washing machine; the fluff is continuously dried. The invention has the advantages of complete burnt-out and the like.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a preparation method of burnt-out polyester six-grid cloth. Background technique [0002] Burnt-out polyester six-grid fabric refers to: the bottom surface is nylon with a hexagonal weave pattern, the surface is polyester, the polyester on the surface is treated with burnt-out in a certain pattern, and the underside of the burnt-out part is exposed. The fabric is lace-like in the burnt-out part, and polyester fabric in other parts. This kind of fabric not only has a burnt-out pattern, but also has a certain degree of transparency in the burnt-out part, and has a very good market prospect. [0003] The polyester-nylon six-grid fabric is different from the suede burnt-out such as the polyester-nylon-ammonia non-velvet burnt-out on the roller machine in the past. The polyester-nylon six-grid fabric with the same weight has poor elasticity. It will cause the slurry to not fully penet...

AI Technical Summary

Problems solved by technology

[0003] Polyester nylon six-grid cloth is different from suede burnt-out such as polyester nylon ammonia non-inverted and other suede burnt out on the roller machine in the past. The cloth surface of polyester nylon six-grid fabric with the same gram weight is less elastic, and the normal burnt-out sizing process is used It will cause the slurry to not completely penetrate the back of the cloth, resulting in endless burnout on the bottom plate of the cloth, resulting in defective products

[0004] Furthermore, the existing process has the situation of scratching the surface of the non-burnt-out parts of the fabric. The existing method uses a scraper to apply the burnt-out alkaline slurry on the gravure cylinder, and then passes the cloth and the cylinder. The contact of the plate makes the burnt-out alkaline paste adhere to the cloth,
