The traditional snowflake frying method is that dry pumice is soaked in potassium permanganate solution, and then the pumice and jean fabric are fried in a machine at regular time, and the fabric style like snowflake patterns is formed on the faded fabric. However, pumice is not beneficial to recycling, so that the pumice is greatly lost, and the crushed pumice slag is subjected to secondary sewage treatment to form a large amount of waste sand, so that the cost is high, the environment is not protected, and the sustainable development is not realized.
There have been many attempts to replace pumice stones with cotton or gum balls, which have been continuously sought in the snowflake frying process. Although the effect of frying snowflakes can be produced, and the repeated use can be realized. However, compared with the snowflake frying effect caused by using pumice, the snowflake frying effect realized by cotton balls or rubber balls is different and not natural enough, and the snowflake frying effect cannot be widely applied.

Soaking towel cloth in potassium permanganate solution (potassium permanganate is mixed with 1% phosphoric acid in equal proportion) for about 1 minute, and dehydrating for 10 seconds at a rotation speed of 1100r/min to make the liquid content of the small cloth pieces about 80%.
(2) The method comprises the steps of desizing and washing 20 gray jeans (brand: Damaoru, style: 190726&727), placing the jeans to an industrial washing machine (brand: Yinhuang, model: XGP-290(630P)), adding alkaline oil (the concentration in water is 1g/L) and a dye-resistant agent (anti-ballistic high-efficiency dye-resistant powder AS-6, the concentration in water is 1g/L), washing at 50 ℃ for 10 minutes, washing with cellulase (Novien polishing enzyme 8000L, the concentration in water is 0.5g/L), washing at 40 ℃ for 15 minutes, removing wool, washing with clear water, dehydrating, and drying with a dryer at 70 ℃.

The terry cloth is adopted to replace pumice, and the good water absorption and buffering performance of the terry cloth enable the noise generated in the production process to be reduced by 2-4 decibels, so that the noise pollution is reduced; meanwhile, the cushioning effect of the damping device also plays a certain role in protecting mechanical equipment.
Comparative example 1
Compared with the example 1, in the comparative example 1, pumice is adopted to fry the black denim into snowflakes, wherein the diameter of the pumice is 2-4 cm, a 20% potassium permanganate solution is uniformly sprinkled on the pumice by using a sprinkler bucket, and the rest production processes are basically the same as those in the example 1. The pumice stone after use is partially lost, and the cost and difficulty of sewage treatment are increased.
As shown in figure 2, the snowflake spots obtained by adopting the process of frying snowflakes by using pumice are clear and natural, and the effect is better.
Comparative example 2
In comparison with example 1, in comparative example 2, black denim is fried with snowflakes using cotton balls having a diameter of about 4cm, and a 6.5% potassium permanganate solution is uniformly sprinkled on pumice using a shower bucket, and the remaining production process is substantially the same as in example 1. The cotton ball can be reused after being cleaned.
As shown in figure 3, when cotton balls are used for frying snowflakes, snowflake points formed on the jean fabric are clearly black and white, irregular snowflake stripes are cotton ball-shaped round spots, the snowflake-shaped spots are large, and the customer acceptance is not high, so that the method is not widely applied in practice.
Comparative example 3
Compared with the example 1, the snowflake frying of the black jean is carried out by adopting the rubber ball in the comparative example 3, wherein the diameter of the rubber ball is about 2cm, and the potassium permanganate solution with the concentration of 10% is uniformly sprinkled on the pumice by using the sprinkler barrel, and the rest of the production process is basically the same as the example 1. The rubber ball can be reused after being cleaned.
As shown in figure 4, snowflake is fried by using the rubber balls, snowflake points formed on the jean fabric are clearly black and white, the surface of the jean fabric is gray, irregular snowflake stripes are in rubber ball-shaped round points, and snowflake-shaped spots are slightly larger. As the glue balls are adopted for frying snowflakes in the production process, the clothes fabric is easy to be stained, the defective rate is increased, and the glue balls are not commonly used in the actual production
In summary, the snowflake frying effect of example 1 using terry cloth was quite similar to the snowflake frying effect of comparative example 1 using pumice, compared to comparative examples 2 and 3, indicating that terry cloth can be used instead of pumice to achieve a good snowflake frying effect.
