2. Stone washing/stone washing is to add a certain size of pumice to the washing water to polish the pumice and clothes. The water level in the polishing tank is at a low level that completely soaks the clothes, so that pumice can contact the clothes well. Generally, washing or rinsing can be performed before the stone mill, and rinsing can also be performed after the stone mill. According to different requirements of customers, Yellowstone, Baishi, AAA stone, artificial stone and rubber ball can be selected for washing to achieve different washing effects. After washing, the cloth is gray and old, and the clothes are slightly to severely damaged.
3. Enzymatic washing enzyme is a kind of cellulase, which can degrade the fiber structure at a certain PH value and temperature, make the cloth surface gently fade and depilate (produce "peach skin velvet" effect), and obtain a lasting soft effect. Stones can be used together or instead of stones. If used with stones, it is usually called enzyme stone washing.
4. Sand washing Sand washing uses some alkaline and oxidizing additives to make clothes have a certain fading effect and a sense of obsolescence after washing. If matched with a stone mill, a layer of soft frosty fluff will be produced on the surface of the washed cloth, and some softener will be added to make the washed cloth soft, thus improving the comfort of wearing.
5. Chemical washing Chemical washing mainly achieves the purpose of fading by using strong alkali additives (NaOH, NaSiO3, etc.). ). After washing clothes, there is obvious sense of obsolescence, and then adding softener, clothes will have a soft and plump effect. If stone is added to the chemical washing, it is called chemical stone washing, which can enhance the fading and wearing effect, thus making the clothes have a strong sense of shabby. Fossil washing combines the effects of chemical washing and stone washing, and can achieve an effect of imitating old pilling after washing.
6. Bleaching and Washing In order to make the clothes have a white or bright appearance and soft hand feel, it is necessary to rinse the clothes, that is, after ordinary washing with clear water, heat them to 60℃, add an appropriate amount of bleach according to the depth of the bleached color, and make the color reach the mosaic within 7- 10 minutes. During operation, the direction of adding bleaching agent should be consistent with the rotation direction of the drum, so as to avoid the bleaching agent falling directly on the clothes because it cannot be diluted with water as soon as possible, resulting in local bleaching. Before bleaching, the water level in the water tank should be slightly higher to dilute the bleaching water. After the clothes are bleached, use large (small) soda (Na2CO3, NaHCO3) to neutralize the residual bleaching water in the water, so as to completely stop the bleaching. After clean water, add detergent, fluorescent whitening agent and hydrogen peroxide. Final washing, PH neutralization, fluorescent whitening, etc. are carried out at a water temperature of 50 C.. , and finally softened. Rinsing can be divided into oxygen bleaching and chlorine bleaching. Oxygen bleaching is to use the oxidation of hydrogen peroxide at a certain PH value and temperature to destroy the dye structure, thus achieving the purpose of fading and whitening. Generally, the bleached cloth will be slightly red. Chlorine bleaching destroys the dye structure by the oxidation of sodium hypochlorite, thus achieving the purpose of fading. Chlorine bleaching has a rough fading effect and is mostly used to rinse indigo denim. After bleaching the board, the residual chlorine in water and clothes is neutralized with high waves to stop bleaching, and then bleached with a stone mill, which is called bleaching stone.
7. Destroy the washed clothes, and after pumice polishing and auxiliary treatment, some parts (bone position, collar angle, etc. ) will be damaged to a certain extent, and the washed clothes will have obvious wear-out effect.
8. Snowflake washing Soak the dried pumice in potassium permanganate solution, and then polish it directly with clothes in a special roller. When pumice is polished on clothes, the friction points are oxidized by potassium permanganate, and the cloth surface is irregularly faded, forming white spots similar to snowflakes. The general process of snowflake washing is as follows: soaking pumice with potassium permanganate-dry grinding pumice and clothes-the effect of snowflake on the board-taking out clothes and washing the stone chips on the clothes with clean water in the washing tank-neutralizing with oxalic acid-washing with water softener.
9. The moustache effect is a whisker, but the term whisker is more professional. A moustache is a kind of hand brush, but it is ground into the shape of a moustache. 10 is also called stone blasting/sandblasting. It uses special equipment (figuratively speaking, it is a large electric toothbrush, just a roller type) to polish cloth, and generally uses an inflatable model.
1 1, the essential difference between monkey washing and sand blasting is that the former is chemical action and the latter is physical action. Stirrup spraying is to spray potassium permanganate solution on clothes according to the design requirements with a spray gun, and a chemical reaction occurs to make the cloth fade. The fading degree is controlled by the concentration of potassium permanganate and the injection amount. From the effect point of view, the sprayed stirrup fades evenly, which can realize the fading of the surface layer and the inner layer and achieve a strong fading effect. But sandblasting only fades on the surface, and you can see the physical damage of the fiber.
12, paint washing/paint dyeing is also called "one-sided coating/paint dyeing", which means that this washing method is specially designed for paint-dyed clothes, and its function is to consolidate the original bright colors and increase the softness of hand feel.
13. Enzymatic washing enzyme is a kind of cellulase. At a certain PH value and temperature, it can degrade the fiber structure, make the cloth surface fade gently, shed hair (produce "peach skin velvet" effect), and get a lasting soft effect. Stones can be used together or instead of stones. If used with stones, it is usually called enzyme stone washing. The former uses a spray gun to spray each potassium permanganate solution on the clothes according to the design requirements, and a chemical reaction occurs to make the cloth fade. The fading degree is controlled by concentration and injection amount. Sandblasting is also called sanding. Polishing cloth with special equipment (figuratively speaking, it is a large electric toothbrush, but it is a roller type). There is usually an inflatable model to match. In terms of effect, the former fades evenly, and both the surface and inner layers fade, which can achieve a strong fading effect. The latter only fades on the surface layer, which shows the physical damage of the fiber.
