[0112] 100% pure cotton combed cotton yarns 1#-4# of 4 different finenesses are dyed, and the steps of dyeing include:

[0113] (1) Loose winding process: the yarn is wound layer by layer onto the dyeing tube to form a bobbin yarn with a density of 0.38-0.4g / m 3 ;

[0114] (2) cheese dyeing process: the dyeing process is:

[0115] ①Pretreatment step: Mix 0.3-0.5g / L chelating agent, 3g / L-4g / l refining agent, 3g / L-4g / l caustic soda and 6g / L-8g / l hydrogen peroxide at 60°C and heat at 100°C Reaction 40min;

[0116] ② Dyeing step: react at 80°C for 5 minutes, cool down to 55°C, add 0.8-1.2g / L neutralizing acid, 0.1-0.2g / L deoxygenase, then raise the temperature to 55°C and keep for 20min, then cool down to 50°C Add 3%-5% dye, 10-20g / L

[0117] For Yuan Mingfen, heat up to 60°C for 15 minutes, add soda ash, keep for 40 minutes, cool down to 50°C and add soap, heat up to 98°C for 15 minutes.

[0118] (3) Knitting process: the dyed yarn i...

Embodiment 2

[0128] Embodiment 2 liquid ammonia finishing

[0129] The 75 100% combed cotton yarns dyed in Example 1 are subjected to functional after-finishing including the liquid ammonia finishing process through the pure cotton knitted fabric 1# weaved by weft knitting, and the speed of the liquid ammonia finishing process is 10- 25m / min, the surface of the guide roller is made of rubber material, including the following steps:

[0130] 1) adjusting the moisture content of the knitted fabric to be lower than 10%;

[0131] 2) The knitted fabric prepared in step 1) is soaked in ammonia twice in the ammonia soaking tank through the guide roller group 130, and the ammonia soaking amount is controlled to be 30%-70% of the dry weight of the knitted fabric, and the padding pressure is 70bar~100bar ;

[0132] 3) Pass the knitted fabric prepared in step 2) through the first felt cylinder of the reaction unit, the temperature of which is 90-110°C, and the second tension is 54-67N;

[0133] 4)...

Embodiment 3

[0141] Embodiment 3 stereotype finishing

[0142] The pure cotton knitted fabric 1# obtained in Example 2 was subjected to a shaping finishing process to obtain pure cotton knitted fabrics 5#-8# and comparative pure cotton knitted fabrics D5#-D7#. The setting temperature of the setting finishing process is

[0143] 160-200°C, the speed of shaping machine is 25-35m / min.

[0144] Styling agents include: 10-100g / L Shanghai Yayun KC-77 softener, 10-60g / L Huntsman SI polyurethane elastic additive, 20-100g / L Huntsman RCT resin, 4-30g / L Huntsman MO catalyst and 10-60g / L Hong Kong Advanced Chemicals HI-40 fiber protection agent.

[0145] The parameters and test structure of the specific finishing process of pure cotton knitted fabrics 5#-7# and comparative pure cotton knitted fabrics D5#-D7# are shown in Table 4. Among them, the test method of air permeability (mm / s) refers to GB / T 5453; the test method of washing dimensional change rate (%) is: ISO 6330; the test of non-ironing (g...

Abstract

The invention discloses a knitted fabric containing natural fibers, a making method and liquid ammonia device for the knitted fabric and a shirt made from the knitted fabric, and belongs to the fieldof fabrics and clothing. The making method for the knitted fabric containing the natural fibers comprises the steps that a knitting method is adopted for making yarns containing the natural fibers into an original knitted fabric, and the knitted fabric is subjected to functional after-finishing comprising a liquid ammonia finishing process. The liquid ammonia finishing process is that the knittedfabric is subjected to ammonia soaking at least twice under the mechanical restraint condition of a guide roller set, it can be avoided that edge rolling is caused to the knitted fabric due to high-degree shrinking in the ammonia soaking process, the knitted fabric can also be subjected to ammonia soaking sufficiently and evenly, the ammonia soaking effect is ensured, and the shrinking rate of theknitted fabric is controlled; through the subsequent setting finishing processes, the color stability of the knitted fabric is further improved, the rate of shrinkage after washing is reduced, and the wrinkle resistance and resilience of the knitted fabric are improved. The shirt is low in rate of shrinkage after washing, good in stiffness and smoothness draping and resilience, stable in color, high in strength and good in wrinkle resistance.

Description

technical field [0001] The present application relates to a knitted fabric, a manufacturing method thereof, a device for use, and a prepared garment, in particular to a knitted fabric containing natural fibers, a manufacturing method thereof, a liquid ammonia device for use, and a shirt prepared by using the knitted fabric, belonging to the field of fabric and clothing. Background technique [0002] Knitted fabrics have the characteristics of high elasticity and comfortable wearing, but there are great limitations in wideness, dimensional stability and shrinkage. After being made into clothes and worn for a period of time, after several washings, the deformation is often serious, which affects the appearance of the clothes, and especially cannot meet the requirements of business shirts. Moreover, the luster of knitted fabrics produced by traditional techniques is not bright enough, and the handle is not soft enough. Although the gloss is better after caustic soda mercerizing...
