Embodiment 1

[0018] (A) Select raw materials, use 32 cotton as the fabric, and steamed polyester low-stretch yarn as the base material, of which 32-count cotton accounts for 30% by mass, and polyester low-stretch yarn accounts for 70% by mass.

[0019] (B) Use a 30-inch 22-pin single-sided machine for programming.

[0020] (C) Dyeing: In the high-temperature and high-pressure dyeing machine, disperse dyes are used to dye the fabric. When the temperature reaches 60℃, the cloth is fed in, and when the temperature rises to 130℃, it is kept warm. The temperature rise time is 80min, and the heat preservation time is 40min. Cool down to 40℃ for fabric.

[0021] (D) Trimming, rub the dyed cloth with a roller covered with sand skin on the cloth surface to grind a layer of fluff on the cloth surface; use a 24-roller high-speed grabbing machine to grab the bottom surface of the cloth 4 times, control the cloth speed of the hair 20m / min; go through the carding machine to comb the hair, and the cloth speed ...

Embodiment 2

[0024] (A) Select the raw material, use 40 cotton as the fabric, and steamed polyester low-elastic yarn as the base material, of which 40-thread cotton accounts for 40% by mass, and polyester low-elastic yarn accounts for 60% by mass.

[0025] (B) Use 34-inch 20-pin single-sided machine for programming.

[0026] (C) Dyeing: In the high-temperature and high-pressure dyeing machine, disperse dyes are used to dye the fabric. When the temperature reaches 80°C, the cloth is inserted, and when the temperature rises to 140°C, heat preservation is performed. The temperature rise time is 100min, and the heat preservation time is 60min. Cool down to 50°C for cloth.

[0027] (D) Trimming, rub the dyed cloth with a roller covered with sand skin on the cloth surface to grind a layer of fluff on the cloth surface; use a 24-roller high-speed grabbing machine to grab the bottom surface of the cloth 2 times, control the hair grabbing speed of 30m / min; after the carding machine for combing, the cardi...

Embodiment 3

[0030] (A) Select raw materials, use 40 cotton as the fabric, and steamed polyester low-elastic yarn as the base material, of which 40-thread cotton accounts for 35% by mass, and polyester low-elastic yarn accounts for 65% by mass.

[0031] (B) Use a 30-inch 20-pin single-sided machine for programming.

[0032] (C) Dyeing: In the high-temperature and high-pressure dyeing machine, disperse dyes are used to dye the fabric. When the temperature reaches 60°C, the cloth is inserted, and when the temperature rises to 130°C, heat preservation is carried out. The temperature rise time is 70min, and the heat preservation time is 30min. Cool down to 45℃ for cloth.

[0033] (D) Trimming, rub the dyed cloth with a roller covered with sand skin on the cloth surface to grind a layer of fluff on the cloth surface; use a 24-roller high-speed grabbing machine to grab the bottom surface of the cloth 3 times, control the cloth speed of the hair to 25m / min; go through the carding machine to comb the ha...

Abstract

The invention discloses a sweater fleece falling prevention technology. The technology comprises processes of raw material selecting, dyeing, fleece finishing and sizing. The fleece finishing process with sanding, fleecing, carding, ironing and shearing is carried out after dyeing, so that produced sweater fleeces are soft and comfortable and can be prevented from falling and piling, and moreover, the sweater cannot easily deform after being washed and has high warm-keeping performance.

Description

Technical field [0001] The invention relates to the field of knitted fabric manufacturing, in particular to a fuzzing process for sweaters that can prevent depilation and pilling. Background technique [0002] Sweatshirt cloth is a kind of knitted cloth, English is fleece. This kind of knitted fabric is woven with displacement-type pad yarn, so it is called displacement cloth or sweater cloth. [0003] Sweater cloth is generally terry cloth, and the weft knitting organization of knitted terry cloth generally uses padding organization. The padding organization is also called the pile organization or the sandwich organization. It is to knit the loop at the same time. Several pad yarns form unclosed loop arcs on some loops of the fabric according to a certain proportion, and float on the rest of the loops and stay on the fabric instead of weft knitting. There are three types of unclosed loop arcs and floating yarns in the fabric: straight cushion, mixed and displacement. The straigh...
