Problems solved by technology

However, due to the low hygroscopicity and high crystallinity of polyester, polar fleece fabrics are prone to static electricity, lipophilic, and easy to stain. Therefore, anti-static and anti-fouling treatments are required.

Abstract

The invention provides a spinning process of polyester fleece knitted fabric. The spinning process mainly uses polyester filaments and polyester staple fibers as the raw materials to prepare the weft-knitted fabric. The spinning process includes: preprocessing gray fabric; dyeing and printing; softening and pre-forming; napping; carding; shearing; turning naps into granular naps; performing kinetic energy finishing; performing finished-product forming. The polyester fleece knitted fabric spun by the spinning process is soft and fluffy in touch, breathable and warm-keeping, less prone to pilling and fading, excellent in water resistance, oil resistance and fouling resistance and durable in flame retardance and can still have excellent three proofing and flame retardance after being washed at normal temperature.

Description

technical field [0001] The invention belongs to the technical field of weaving, and in particular relates to a weaving process of polyester polar fleece knitted fabric. Background technique [0002] With the continuous development of society, various synthetic fiber fabrics come out one after another. Polar fleece is a kind of knitted fabric. It is a small ingot knitting structure. It is woven on a large circular machine. After weaving, the gray fabric is dyed first, and then processed by various complex finishing processes such as napping, carding, shearing, and shaker. Treatment, the front side of the fabric is napped, the fleece is fluffy and dense, and it is not easy to shed and pilling, the reverse side is sparsely and evenly napped, the fluff is short, the texture is clear, and the fluffy elasticity is very good. Its ingredients are generally all polyester, soft to the touch, and it is the first choice for keeping out the cold in winter. [0003] In addition, polar f...
