Description

TECHNICAL FIELD

[0002] "Waterless and no jeans", washing water is a key step for forming jeans, and its function is to make jeans softer for wearing and to beautify jeans. Common washing water processes include general washing, stone grinding fermentation washing, enzyme washing, sand washing, chemical washing, rinsing, damage washing and horse washing. Fermentation washing is one of the most widely used processing methods for jeans water washing, and through cellulase erosion on the surface of fibers, the fabric surface is abraded and the dyes on the fabric are stripped, thereby giving the denim a unique vintage style. Using cellulase to restore the old style of denim has the advantages of high production efficiency, good processing quality, good drape and softness of the treated fabric, etc. However, the traditional fermentation washing still needs to be combined with floatstone, and has the disadvantages of large water consumption, large sewage discharge and a large amount of sludge, etc. Therefore, the existing technology still needs to be improved and developed.

[0003] Patent CN 114438770 A discloses a waterless fermentation grinding washing method for jeans, wherein the fermentation grinding uses a composite enzyme agent composed of AQUALESS AGED enzyme and GW-88V enzyme water to finish the jeans, without water as a reaction or treatment medium, thereby reducing water consumption. However, floatstone is still needed, which causes great damage to the fabric. This problem needs to be solved urgently. SUMMARY

[0004] The purpose of the present application is to provide an energy-saving and environment-friendly waterless and floatstone-free denim fabric fermentation washing aid and process.

Compared with traditional fermentation washing and stone grinding fermentation washing, the water consumption and the amount of floatstone can be significantly reduced, the cost can be greatly saved, the sewage discharge can be reduced, the sludge generation can be reduced, and the waterless and floatstone-free fermentation washing aid has better anti-backstaining effect than traditional enzyme water, which can effectively reduce the use of anti-backstaining chemical aids and improve the grade of the garment.

[0076] Select 10 experienced cowboy wash master, observe the flower degree of jeans skirt, the four aspects are divided into 1-5 level, 1 (poor), 2 (good), 3 (general), 4 (good), 5 (best) 5 categories, the experimental clothing is evaluated, the result is the average value.

[0077] 2, tearing strength analysis after fermentation washing

[0078] Fabric tear strength comparison according to GB / T3917.1-2009 "Textiles- Determination of tear resistance of fabrics- Part 1: single-pendulum method", using YG(B)003A fabric tearing instrument, 10 samples of longitudinal and transverse direction were cut from the sample 100mm away from the selvedge with the specified size of sample template, the pendulum was lifted to the vertical position, i.e. the starting position of the test, and the pointer was pushed to the stop plate, the bottom edge of the semicircular sample was placed in the middle of the bottom of the two clamps, then the two clamps were tightened, the cutter handle was pressed to cut a 20mm long notch in the middle of the sample from the bottom to the top, the data was checked, 10 times were measured, the average value was taken, and the damage rate after fermentation was calculated.

[0079] Damage rate after fermentation = [(fabric tear strength after fermentation - fabric tear strength after desizing) / fabric tear strength after desizing] x 100%

[0080] 3. Dyeing prevention effect test after fermentation

[0081] The pocket cloth of the jean skirt after fermentation and drying was laid flat on a flat table, and its whiteness was measured using a 3NH-NR10QC whiteness meter, 10 times for each pocket cloth, and the average value was taken.

[0082] The performance test results of the products before and after washing in Examples 1-2 and Comparative Examples 1-5 are as follows:

[0083] 1. The picture table of the fermented garment is as shown in Figures 1-4

[0084] 2. The flower degree evaluation table after fermentation is shown in Table 1:

[0085] Table 1. Flower degree evaluation table after fermentation

[0086]

[0087] Combined Figures 1-4 with Table 1 data, it can be seen that under the same other process conditions, using 1kg waterless and floatstone-free fermentation aid HS-NKT waterless fermentation for 50min, and using 2kg waterless and floatstone-free fermentation aid HS-NKT waterless fermentation for 35min can achieve the flower degree and three-dimensional effect of traditional fermentation with floatstone, and comparing Example 1 with Comparative Examples 3, 4 and 5, it can be seen that not adding starch, guar gum or fatty alcohol polyoxyethylene ether will cause the flower degree to be slightly worse, indicating that starch, guar gum and fatty alcohol polyoxyethylene ether in the formula have a synergistic effect with the enzyme, promoting and improving the effect of fermentation.

[0088] 3. Fabric tear strength test after fermentation is shown in Table 2.

[0089] Table 2

[0090] ​

[0091] From the data in Table 2, it can be clearly seen that, compared with Comparative Examples 1, 2 and Comparative Examples 1, 2, the use of the non-aqueous non-stone washing enzyme HS-NKT can ensure good washing flower effect and three-dimensional effect, and the damage to the fabric is greatly reduced. Comparative Example 1 and Comparative Example 3 can see that without starch, the damage force will be significantly reduced, which is due to the synergistic effect of starch and enzyme, which can help better flower and increase the damage force of good flower. Therefore, without the synergistic effect of starch, the damage force will be greatly reduced. At the same time, by comparing Example 1 with Comparative Examples 4 and 5, it can be clearly seen that the absence of guar gum or polyoxyethylene ether will cause the damage force to increase slightly, indicating that guar gum and polyoxyethylene ether in the formula have a synergistic effect with neutral cellulase. Under the premise of ensuring the flower degree, the damage force to the fabric is reduced.

[0092] 4. The effect of dyeing is shown in Table 3.

[0093] Table 3

[0094]

[0095] In Table 3, "L" represents the lightness of the fabric, "+ value" represents the brightness, "- value" represents the darkness; "a" represents the degree of red or green light of the fabric, "+ value" represents the degree of red, "- value" represents the degree of green; "b" represents the degree of yellow or blue light of the fabric, "+ value" represents the degree of yellow, "- value" represents the degree of blue. Since the selected denim is blue denim, the "L" value and "b" value are mainly observed. From the table, it can be clearly seen that the fabric color of Example 1 and Example 2 is brighter, and the degree of blue is shallower, while the fabric color of Comparative Example 1 and Comparative Example 2 is darker, and the degree of blue is deeper, indicating that the dyeing effect of non-aqueous non-stone washing enzyme HS-NKT is better. By comparing Example 1 with Comparative Examples 3, 4 and 5, it can be clearly seen that the absence of starch and guar gum will reduce part of the dyeing effect, and the absence of fatty alcohol polyoxyethylene ether will significantly reduce the dyeing effect. It can be seen that starch, guar gum and fatty alcohol polyoxyethylene ether have certain synergistic effect on improving the dyeing effect.

[0096] 5. The washing process is shown in Table 4.

[0097] Table 4

[0098]

[0099]

[0100] The process data of the first fermentation in the experiment is shown in Table 4, and it can be seen from the table that the use of the anhydrous and floatstone-free fermentation aid HS-NKT can ensure good fermentation flower effect and three-dimensional effect, reduce a large amount of industrial water, floatstone and sewage discharge, and make the jean washing more environmentally friendly.
