Embodiment 1

[0039] The sample is a white pure cotton plain fabric, using pure cotton 11.7tex yarn in the warp and weft directions, with a warp density of 137 threads / inch, a weft density of 78 threads / inch, and a gray fabric of 1,300 meters. The conventional pretreatment process of the fabric is desizing→scouring, Bleaching→mercerizing→liquid ammonia, leave half a meter of fabric for K / S value test in each process. Take another 50 meters of boiled and bleached fabric, do not mercerize, only do liquid ammonia, leave half a meter after the liquid ammonia, and process the rest for mercerizing, and test the K / S without processing mercerizing, only processing liquid ammonia, first liquid ammonia and then mercerizing value. in:

[0040] Desizing process: desizing enzyme DS-HT 8g / L, penetrant WAM 3g / L, refining agent SAU 2g / L, vehicle speed 65m / min, trough temperature about 50°C, steam at 100°C for 15 minutes, wash with water The tank temperature was set at 80°C, 90°C, 90°C, 80°C, and 70°C in ...

Embodiment 2

[0060] The sample is 5 pieces of white pure cotton satin fabric, the warp and weft directions are made of pure cotton 7.3tex plied yarn, the warp density is 127 threads / inch, the weft density is 83 threads / inch, the gray fabric is 4200 meters, the fabric is pre-treated and desized → boiled After scouring, bleaching, desizing, and boiling and bleaching, leave half a meter to test the K / S value.

[0061] Take 50 meters for mercerizing, leave half a meter for test after mercerizing, and test the K / S value of mercerizing without liquid ammonia, first mercerizing and then liquid ammonia respectively. Take another 50 meters to make liquid ammonia, leave half a meter after the liquid ammonia, and process the rest for mercerizing, test the K / S value of not processing mercerizing, only processing liquid ammonia, first liquid ammonia and then mercerizing. in:

[0062] Desizing process: desizing enzyme DS-L7g / L, penetrant WAM 2g / L, refining agent SAE2g / L, vehicle speed 63m / min, trough t...

Embodiment 3

[0081] The sample is a white pure cotton 3 / 3 positive and negative twill weave fabric, the warp and weft directions are made of pure cotton 14.6tex yarn, the warp density is 142 threads / inch, the weft density is 68 threads / inch, and the gray fabric is 2300 meters. Pulping → scouring, bleaching → mercerizing, because the fabric is easy to curl with liquid ammonia, only mercerizing is processed, and half a meter of fabric is reserved for K / S value testing in each process. in:

[0082] Desizing process: desizing enzyme DS-L 8g / L, penetrating agent WAM 3g / L, refining agent SAE 3g / L, vehicle speed 62m / min, trough temperature about 50°C, steam at 98°C for 18 minutes, wash the tank with water The temperature was set at 85°C, 90°C, 90°C, 80°C, and 70°C in sequence.

[0083] The scouring and bleaching adopts linkage, scouring process: 48Be° caustic soda 30g / L, penetrating agent WAM 3g / L, refining agent SAE 3g / L, wax remover WR-03 2g / L, vehicle speed 62 m / min, trough temperature Steam...

Abstract

The invention relates to a detection method for judging the treatment degree of a fabric pretreatment procedure through a dyeing method, and belongs to the technical field of textile detection. The method comprises the following steps: dyeing a sample by adopting a rolling dyeing method or an oscillating dyeing method, then testing K / S values, calculating an arithmetic mean value of the K / S values, and firstly judging the degree of the dye adsorption capacity of the pretreatment fabric; and then determining each pretreatment process of the fabric according to the arithmetic mean value of the K / S values. According to the invention, the method is scientific and reasonable in design, the adsorption effect of the pretreated fabric can be accurately judged, meanwhile, the pretreatment procedure of the fabric can be judged, and great help is provided for follow-up dyeing and printing dye saving and quality improvement.

Description

technical field [0001] The invention relates to a detection method for judging the processing degree of a fabric pretreatment process by a dyeing method, and belongs to the technical field of textile detection. Background technique [0002] The pre-treatment effect has a great influence on the subsequent dyeing, printing and other processes of the fabric and the performance of the fabric. At present, there is only an evaluation of the adsorption effect after mercerizing, and there is a lack of evaluation of the adsorption performance of each process of fabric pre-treatment. The adsorption effect after mercerizing is usually expressed by the barium value of mercerizing. The barium value of mercerizing refers to the ratio of the amount of barium hydroxide absorbed by the fabric after mercerizing to the amount of barium hydroxide adsorbed after desizing. According to the size of the barium value, the mercerizing effect is determined, but there is no adsorption on pre-treatments...
