Problems solved by technology

[0002] Most of the shirt fabrics currently popular in the market are cotton blended products, but cotton blended products have the following disadvantages: (1) Cotton products have poor elasticity and are easy to wrinkle; (2) Cotton products have strong water absorption. After it absorbs water, the cotton fiber expands, causing the product to deform and the change rate of the inch method is poor; (3) In a wet state, if the cotton product encounters bacteria or fungi, the cotton fiber will decompose, causing the fabric to become moldy and deteriorated; (4) Cotton products If it is exposed to sunlight for a long time, the strength will decrease, and the fiber will become hard and brittle; (5) the color of cotton products cannot reach a bright level, and the color fastness is low; (6) the pilling performance of cotton short fiber products is very poor, Generally only around 2
Although this method overcomes the problem that cotton fabrics are easy to wrinkle, and also solves the problem of yellowing of traditional non-ironing shirts caused by high baking temperature, it cannot solve the problem of poor size change of cotton products, and the fabric is prone to mildew and deterioration. Low color fastness and poor pilling performance

Embodiment 1

[0038] Using 40S PET MVS yarn and 75D-24f-high-shrinkage PET yarn for cross-knitting, the weave is beaded weave, knitting on a 32G single-jersey machine to form a knitted gray fabric, and the obtained knitted gray fabric contains 75D-24f-high-shrinkage PET yarn The blending rate of the high-shrinkage yarn is 32%, and the boiling water shrinkage rate of its high-shrinkage yarn is 38%. After scouring and desizing in the cylinder (scouring agent 0.5g / l), dyeing with disperse dyes at 130 degrees, resin finishing (hydrophilic agent 10g / l, pH regulator 1g / l), finishing and shaping at 160 degrees, the gram weight is about 200g / m 2 of knitted fabrics. The underfill coefficient of the knitted fabric is 12, and the loop shrinkage rate of the knitted fabric is 14% compared with that before dyeing.

[0039] The knitted fabric has a pilling resistance of grade 4, and the change rate of the washing inch method is -0.7% in the warp direction and -0.2% in the weft direction. The stiffness ...

Embodiment 2

[0041] Using 60S PET MVS yarn and 50D-24f-high-shrinkage PET yarn for cross-knitting, the weave is beaded weave, knitting on a 36G single-jersey machine to form a knitted gray fabric, and the obtained knitted gray fabric contains 50D-24f-high-shrinkage PET yarn The blending rate of the high-shrinkage yarn is 54%, and the boiling water shrinkage rate of its high-shrinkage yarn is 33%. After scouring and desizing in the tank (scouring agent 0.5g / l), dyeing with disperse dyes at 130 degrees, resin finishing (hydrophilic agent 10g / l, PH value regulator 1g / l), finishing and shaping at 160 degrees, the gram weight is about 180g / m 2 of knitted fabrics. The underfill coefficient of the knitted fabric is 15, and the loop shrinkage rate of the knitted fabric is 12% compared with that before dyeing.

[0042] The knitted fabric has a pilling resistance of 4 grades, and the change rate of the washing inch method is -2.0% in the warp direction and -0.3% in the weft direction. The stiffne...

Embodiment 3

[0044] Using 75D-96f-special-shaped section PET DTY yarn and 75D-24f-high-shrinkage PET yarn for interknitting, the weave adopts 1:1 plain jersey weave, and knits it on a 36G single-jersey machine to form a knitted gray fabric. The mixing rate of 75D-24f-high shrinkage PET yarn is 50%, and the boiling water shrinkage rate of its high shrinkage yarn is 38%. After scouring and desizing in the tank (scouring agent 0.5g / l), dyeing with disperse dyes at 130 degrees, resin finishing (hydrophilic agent 10g / l, PH value regulator 1g / l), finishing and shaping at 160 degrees, the gram weight is about 180g / m 2 of knitted fabrics. The underfill coefficient of the knitted fabric is 18, and the loop shrinkage rate of the knitted fabric is 10% compared with that before dyeing.

[0045]The pilling resistance of the knitted fabric is grade 4, and the change rate of the washing inch method is -0.2% in the warp direction and -0.6% in the weft direction. The stiffness in the warp direction is 0...

Abstract

The invention discloses a knitted fabric and application thereof. The knitted fabric is 100% polyester fiber knitted fabric, wherein thirty weight percents to seventy weigh percents yarns are high shrinkage polyester yarns. Longitudinal direction washing dimensional change rate and latitudinal direction washing dimensional change rate of the knitted fabric all are in -0.3%-1.0%. Longitudinal direction rigidity and latitudinal direction rigidity are greater than 0.02gf.cm 2 / cm. Anti-pilling capacity achieves above a three grade. The knitted fabric is suitable for making shirts and the like.
