Preparation method of polyester blanket

Abstract

The invention provides a swelling method of a polyester blanket. An electrothermal stainless steel swelling hot roller is adopted for swelling operation. A groove is formed in the surface of the stainless steel swelling hot roller, polyester greige cloth suede makes direct contact with the surface of the stainless steel swelling hot roller, and the cloth moving direction of greige cloth is the same as the rotation direction of the swelling hot roller. During swelling operation, the surface temperature of the swelling hot roller ranges from 120 DEG C to 210 DEG C, the rotation speed is 200-400 turns per minute, and the cloth moving speed of the greige cloth is 15-20 m / min. The invention further relates to a manufacturing method of the polyester blanket using the swelling method. The manufacturing method sequentially comprises the steps of weaving and cutting, swelling, brushing, lustring and printing, permeating, drying, steaming and washing, shaping, drying, after treatment and obtaining of the product. Polyester low-elastic yarn is swelled, and the functions of warm keeping and increasing the thickness of the blanket are achieved. The manufactured method is simple, low in equipment manufacturing cost, small in occupied area and good in swelling effect.

Description

technical field [0001] The invention relates to an expanding method for a polyester blanket, and also relates to a preparation method for a polyester blanket using the expanding method. Background technique [0002] Raschel polyester blanket is a gray fabric woven by a rasher warp knitting machine with polyester low elastic yarn as a face yarn. After the gray fabric is cut by a cutting machine, it is puffed and shrunk by a high-temperature setting machine, and then brushed, ironed, printed, and steamed. It is processed by steaming, washing, drying and shaping, finishing, wrapping and packaging. The wool height of Raschel blanket is usually 6MM-12MM, and it is divided into upper yarn and lower yarn when weaving. The upper yarn is usually polyester low elastic yarn, also known as DTY, which has 5%-8% elasticity. Low yarn is generally made of polyester full-drawn yarn, also known as FDY, with almost zero elasticity. The thermal expansion and shrinkage process in the current p...
