Problems solved by technology

In the past, the fleece clothing and trousers equipped by the army were ordinary pure cotton knitted brushed fabrics, which could no longer meet the needs of the army under modern conditions in terms of warmth retention and wind resistance. At the same time, it is also necessary to consider the underwear to be worn outside, to adapt to different conditions, complex climate conditions and other needs. For example, the light fastness standard of the cashmere trousers required to be provided must reach level 5 or above, which is used in cellulose Fiber dyeing is hard to do

Embodiment 1

[0051] In the present embodiment, the method for dyeing and finishing fleece pants, described fleece pants adopts 21 S C / 150D French rib fabric is woven and the desired color is pine green.

[0052] Wherein, the fabric is dyed with the following dyes, ingredients and auxiliary agents:

[0053]

[0054] The dyeing process is as follows:

[0055] Putting water into the dyeing machine according to the amount of pre-treated cotton knitted fabrics in the dyeing machine and a predetermined liquor ratio;

[0056] Raise the water temperature to 40°C;

[0057] Add 80g / L sodium bicarbonate, 1g / L leveling agent and 5g / L soda ash to the water in 5 minutes by circular injection, and keep warm at 40°C for 15 minutes;

[0058] Quantitatively with the time of 15 minutes (quantitative in the present invention refers to the function that utilizes equipment to provide, all materials are all added in the time of setting by equipment automatic linearity. The same below) After injecting all d...

Embodiment 2

[0072] This embodiment is a further processing on the basis of Embodiment 1.

[0073] In the traditional method of softening in the water bath of the dyeing tank, the hydrophilic softener is dissolved in water and does not fully adhere and penetrate into the fabric. The effect is very poor and the hand feels rough, not to mention the elastic recovery rate of the fabric, and the cost is relatively high.

[0074] The system soft of present embodiment is to make soft on the sizing machine: about 80L-100L of rolling groove of sizing machine, non-ionic hydrophilic softening agent consumption 15g / l ± 1, according to the following process conditions, the liquid carrying rate is 90%-100% , The setting speed is 20m / min, the overfeed is 20-25% for setting, and the setting temperature is set at 180℃~183℃. The preparation and shaping of the method are simultaneously reduced and the labor efficiency is improved.

[0075] The selection of non-ionic hydrophilic softener in the above process...

Embodiment 3

[0079] This embodiment is a further processing on the basis of Embodiment 2.

[0080] complex:

[0081] 20 with a width of 136cm±2 after setting through the needle board widening machine S C / 150D French rib width to 163cm±2;

[0082] Spray the colloidal particles evenly at 20 S One side of C / 150D French rib polyester;

[0083] Through hot melting, the temperature is 165℃﹢2℃ to melt the rubber particles;

[0084] By pressing, make TEDA cotton with 20 S C / 150D French rib firmly bonded;

[0085] After stacking loose rolls, the 20% cotton compounded with TEDA cotton S The width of C / 150D French rib is retracted to 140cm+2 width.

Abstract

The invention discloses a dyeing and finishing method of napped garments and trousers. The fabric of the napped garments and trousers is dyed by 1.05%owf of 100% Levafix CA blue, 2.4%owf of 100% Cibareactive dark blue S-GL, 2.5%owf of 100% Ciba reactive yellow S-3R and 0.585%owf of 100% Ciba reactive red S-B. The dyeing and finishing method has the advantages that the reactive dark blue S-GL containing s-triazine monofluoride and improved vinyl sulfone double reactive groups and the Levafix CA blue containing two s-triazine monofluoride reactive groups, the dyeing process which needs to add salt and alkali in advance is broken through, and the method is suitable for the dyeing theory of s-triazine monofluoride and vinyl sulfone groups and vinyl sulfone double reactive groups; the method is high in automation level, few in man-made interference factors, precise in bath ratio, simple, easy to control and beneficial to the increasing of dyeing reproducibility.

Description

[0001] The application date of this case is April 29, 2016, and the application number is 201610282020.1. Name of the invention: Divisional application for the dyeing and finishing method of military cashmere underwear technical field [0002] The invention relates to a method for dyeing and finishing fleece clothing. Background technique [0003] With the continuous improvement of people's living standards, people's requirements for clothing have gradually increased from keeping warm to being beautiful and comfortable, and some functional products have also emerged as the times require. With the modernization of national defense in our country, the clothing of the troops is also developing in the direction of comfort, functionality and adaptability. In the past, the fleece clothing and trousers equipped by the army were ordinary pure cotton knitted brushed fabrics, which could no longer meet the needs of the army under modern conditions in terms of warmth retention and wind...
