Problems solved by technology

[0002] In the domestic and foreign markets, polyester single-knit fleece fabrics generally have two problems: the fabric feels hard and has poor elasticity and extensibility.
There are two types of weft-knitted pure polyester fleece fabrics on the market. One is the fleece fabric formed after brushing finishing based on the weft-knitted structure of the second or third liner. Although the density of this type of fabric is relatively tight, it feels hard. , poor elasticity, even if the ultra-fine polyester material of 0.5-0.75DPF is used, the hand feel will still feel hard
The other is the fleece fabric based on the weft-knitted terry structure. Generally, the velvet fabric is formed by cutting loops during the finishing process, and the polyester / spandex core-spun yarn is used as the ground yarn to increase the density of the fabric base fabric and make the wool The fleece is upright and feels good, but the stretch recovery of this kind of gray fabric is still not great

Embodiment 1

[0012] A high-density elastic weft-knitted fleece fabric, using spandex bare silk and polyester network yarn to weave the terry fabric through single-sided weft-knitted terry weaving, and then pulling the elongated settlement arc of the terry structure of the terry fabric Process made. Wherein the ground yarn in the terry gray cloth is 70D spandex bare silk and 75D / 36F polyester network silk double-ply incoming thread. The terry yarn in the terry gray cloth is 100D / 96F polyester network yarn, and the network points of the polyester network yarn are 110-130 pieces / m.

Embodiment 2

[0014] A method for manufacturing a high-density elastic weft-knitted fleece fabric, which includes a weaving step and a napping step in sequence, and the weaving step includes weaving spandex bare yarn and polyester network yarn through a single-sided weft-knitted terry weave into a full-covered terry gray fabric, The napping step includes making the elongated sinker arc of the terry structure into a single-face fleece fabric through the napping process, wherein the ground yarn is 70D spandex bare silk and 75D / 36F polyester network yarn double-ply incoming thread, and the terry yarn is 100D / 96F polyester network yarn, the network point of polyester network yarn is 110~130 pcs / m.

[0015] Wherein, the weaving step specifically includes the following technological process in sequence: yarn preparation, weft knitting, knitting of seams, pretreatment, dehydration, width opening, dyeing presetting, dyeing, dehydration out of cylinders, and drying.

[0016] Wherein, the napping ste...

specific example

[0019] Use 70D spandex bare yarn and 75D / 36F polyester network yarn with 120 points / m network points as the ground yarn, and 100D / 96F polyester network yarn with 120 points / m network point as the terry yarn. Terry fabric is knitted on a terry machine. The technological setting of the movement track of the terry sinker is as follows: the triangle of the terry sinker is adjusted so that the foot point of the terry sinker in the knitting process is 9.5mm away from the outer diameter of the needle cylinder.

[0020] Fabric pretreatment process, dispersing chelating agent: 0.5-1g / l, strong degreaser: 3g / l, soda ash: 1-2g / l, treatment temperature: 95°C, time: 60 minutes, liquor ratio: 1:15.

[0021] Fabric dyeing presetting process, treatment temperature: 190°C, time: 45 minutes, overfeed 12%.

[0022] Fabric dyeing process, using disperse dyes, liquor ratio: 1:10-15, dispersing chelating agent: 0.3-0.5g / l, acetic acid: 0.4g / l, sodium acetate: 0.5g / l, leveling agent: 0.5-1.0 %, te...

Abstract

The invention relates to a high-density elastic weft-knitting fleece fabric and a manufacturing method thereof. The manufacturing method comprises the following steps: uncovered polyurethane fiber andpolyester interlaced set yarn are woven into turn-down terry grey cloth via single weft knitting terry weave; the stretched sinker loop of terry structure is processed into single pile-containing fabric through napping treatment process. Ground yarn of the terry grey cloth is double-ply inlet wire of 70D uncovered polyurethane fiber and 75D / 36F polyester interlaced set yarn. Terry yarn of the terry grey cloth is 100D / 96F polyester interlaced set yarn, and network points of the polyester interlaced set yarn are 110-130 / m. Compared with the weft-knitting velvet fabric, due to adopting uncoveredpolyurethane fiber, elasticity and extensibility of textile are better. Compared with the conventional the treatment process of cut loop fabric of terylene terry fabric, the invention uses the nappingtreatment process of the polyester interlaced set yarn and terry fabric, so that the prepared fabric is soft in feel, plump in loop integrating venting, frivolity, elasticity, softness with keeping warm, which is applicable to manufacturing leisure wear in autumn and winter.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a high-density elastic fleece fabric and a preparation method thereof. Background technique [0002] In domestic and foreign markets, polyester single-knit fleece fabrics generally have two problems: the fabric feels hard and has poor elasticity and extensibility. [0003] As people pursue fashion and leisure lifestyles, more and more people want to wear clothes without restraint and be able to move freely, so higher requirements are put forward for the feel and elasticity of fabrics. There are two types of weft-knitted pure polyester fleece fabrics on the market. One is the fleece fabric formed after brushing finishing based on the weft-knitted structure of the second or third liner. Although the density of this type of fabric is relatively tight, it feels hard. , The elasticity is poor, even if the ultra-fine polyester material of 0.5-0.75DPF is used, the hand feel will still...
