Embodiment 1

[0017] A production process of all-cotton knitted fabric, the process flow is as follows: weaving→turning→singeing→mercerizing→pretreatment→dyeing→dehydration→cutting→drying→silk finishing→finished product.

[0018] (1) During the weaving process, the yarn length is increased by 10-20% on the basis of the conventional weaving yarn length. For example: 40S / 1 cotton jersey, specification 120g, conventional yarn length 24cm / 100G, the yarn length in this process is 27.5cm / 100G, and the yarn length increases by 14.58%; in actual production, the weaving process can be completed on an ordinary circular machine Properly increasing the yarn length is conducive to the shrinkage of the fabric in the mercerizing process, and at the same time can keep the fabric with good elasticity.

[0019] (2) The purpose of singeing is to make the cloth surface smoother and improve the quality and grade of the fabric.

[0020] (3) During the mercerizing process, the mercerizing speed is 9m / min; the me...

Embodiment 2

[0025] A production process of all-cotton knitted fabric, the process flow is as follows: weaving→turning→singeing→mercerizing→pretreatment→dyeing→dehydration→cutting→drying→silk finishing→finished product.

[0026] (1) During the weaving process, the yarn length is increased by 10-20% on the basis of the conventional weaving yarn length. For example: 32S / 1 cotton jersey, specification 150g, conventional yarn length 25cm / 100G, the yarn length in this process is 28cm / 100G, and the yarn length increases by 12%; in actual production, the weaving process can be completed on an ordinary circular machine. Appropriately increasing the yarn length is conducive to the shrinkage of the fabric in the mercerizing process, and at the same time can maintain a good elasticity of the fabric.

[0027] (2) The purpose of singeing is to make the cloth surface smoother and improve the quality and grade of the fabric.

[0028] (3) During the mercerizing process, the mercerizing speed is 14m / min; ...

Embodiment 3

[0033] A production process of all-cotton knitted fabric, the process flow is as follows: weaving→turning→singeing→mercerizing→pretreatment→dyeing→dehydration→cutting→drying→silk finishing→finished product.

[0034] (1) During the weaving process, the yarn length is increased by 10-20% on the basis of the conventional weaving yarn length. For example: 26S / 1 cotton jersey, specification 170g, conventional yarn length is 27.6cm / 100G, the yarn length in this process is 30.4cm / 100G, and the yarn length increases by 10.14%; in actual production, it can be completed on an ordinary circular knitting machine Weaving process. Appropriately increasing the yarn length is conducive to the shrinkage of the fabric in the mercerizing process, and at the same time can maintain a good elasticity of the fabric.

[0035] (2) The purpose of singeing is to make the cloth surface smoother and improve the quality and grade of the fabric.

Abstract

The invention discloses a production process of a full-cotton knitted fabric. The production process of the full-cotton knitted fabric comprises the following steps: knitting, turning, singeing, mercerizing, carrying out pretreatment, dyeing, dewatering, slitting, drying, and smoothing and finishing to obtain a finished product. In the step of knitting, the length of yarns is increased by 10-20% on the basis of the normal knitted yarn length; in the step of mercerizing, a feasible mercerizing speed and a mercerizing formula are made, and the transverse breadth of the fabric is increased by 15-25% by overfeeding; in the step of carrying out pretreatment, caustic soda, alkali-proof refined penetrant, anticrease agent of cotton and hydrogen peroxide are selected; in the step of dyeing, the addition time of anhydrous sodium sulphate and the addition time of sodium carbonate are prolonged in comparison with the conventional addition time; in the step of smoothing and finishing, a smoothing and finishing agent is compounded by amino modified silicone oil and a water-based polyether type polyurethane finishing agent according to a weight ratio being (1.8:1)-(2.2:1). The production process of the full-cotton knitted fabric has the advantages that the full-cotton knitted fabric produced by the process has high elasticity and smooth hand feeling, and is bright and clean, good in size and shape stability and excellent in pendency performance.

Description

technical field [0001] The invention relates to a production process of an all-cotton knitted fabric, belonging to the field of fabric production. Background technique [0002] In recent years, with the development of science and technology and the improvement of people's living standards, people have higher requirements for the fabric quality of clothing fabrics such as feel, appearance, color, size and shape stability. And the all-cotton knitted fabric produced by using conventional production technology (such as: the authorized announcement number is CN101200852A, a kind of processing method of low-elasticity non-ironing knitted fabric) that appears on the market now does not have high elastic performance, and the luster of the fabric is dim, and the cloth The surface is less smooth, the dimensional stability is poor, and the drape performance is not good, which can no longer meet people's requirements for clothing fabrics. Contents of the invention [0003] The techni...
