Common method of water washing

1. Garment Wash

牛仔水洗工艺详解 才智服装制版

Generally, ordinary washing is ordinary washing, but the washing we are familiar with usage to mechanization is only about 60 ° -90 ° C. After a certain amount of detergent, after about 15 minutes of ordinary washing, the water and soft water plus soft water and softness The agent can make the fabric softer, comfortable, and more natural and cleaner visually. Usually, according to the length of the washing time and the amount of chemicals, the general washing can be divided into light washing, general washing, and heavy cleaning. Usually lightly washing is about 5 minutes, the general washing is about 15 minutes, and the re -washing is about 30 minutes. (This time is inaccurate). These three ways of washing have no obvious boundary.

2. Stone washing / stone mill (Stone Wash)

The stone washing is to add a certain size of the floating stone to the water washing, so that the floating stones and clothes are polished. The water level in the polishing tank is performed with the low water level of the clothing completely soaked to make the floating stone contact the clothes well. You can wash or rinse before the stone mill, or rinse after the stone mill. According to the different requirements of customers, it can be washed with yellow stones, white stones, AAA stones, artificial stones, rubber balls, etc. to achieve different water washing effects. Essence

3. Enzyme Wash

Enzyme is a type of cellulose enzyme that can degrade the fiber structure at a certain pH value and temperature, so that the cloth surface can fade more mildly, fade (produce “peach skin” effect), and obtain lasting soft softness Effect. It can be used or replaced by stones. If it is used with stones, it is usually called Enzyme Stone Wash.

4. Sand Wash

Sand washing is mostly alkaline and oxidized auxiliary, so that the clothing has a certain fading effect and an old sense after washing. If it is matched with stone grinders, the surface of the fabric will produce a layer of soft frost white fluff, and then some soft agents will be added, and some soft agents will be added. It can make the fabric soft and soft after washing, thereby improving the comfort of wearing.

(1) Sand washing agent

a) Pole agent: According to the category of fiber, the tissue structure and tightness of the fabric are selected to select the puffer and concentration, temperature, time and other pussy conditions. When the cotton clothing is washed Essence

b) Sand washing agent: After the clothing is swollen, fiber is loose, and then the regulation helps special sand washing for friction, so that the loose surface fiber produces plump and soft hairs. If you want to make the fluff plump, you must choose different forms, different hardness, Sand powder, if you can use diamond -shaped sand (make the loose fiber produced fluff), polygonal sand (stretch the velvet), and round sand (plump fluff).

c) soft agent: soft agent for sand washing. It is required to achieve soft and waxy, so that the fabric can gain weight, and the hangingability should be significantly improved. Therefore, this kind of soft agent carbon chain must be long and has cordonality, which can adsorb on the fabric to achieve weight gain.

(2) Sand washing equipment

牛仔水洗工艺详解 才智服装制版

At present, it is generally used in industrial water washing machines for puffing, sand washing and soft treatment. It is dehydrated with a centrifugal pump dehydrator.

(3) Sand washing process

Cotton cloth clothing can determine the amount and time, time, and treatment temperature and time of the pouring agent according to the tissue structure, the latitude and weft density and the thickness of the gauze, and the strength of the twist. Choose yarn fabric sand washing effects better than wire fabrics, rough yarn is better than high yarn, low twist is better than high twist, and the floating point is better than floating -point short products.

5. Chemical Wash

Chemical washing is mainly to achieve the purpose of fading by using a strong alkaline auxiliary (NAOH, NASIO3, etc.). After washing, the clothes have a more obvious old sense of oldness, and then the soft agent is added. The clothing will have a soft and plump effect. If stones are added to chemical washing, it is called Chemical Stone Wash, which can enhance the fading and wear effect, so that the clothing has a strong sense of remnants. After washing, it can achieve an imitation and hair effect.

6. Rinse (Bleach Wash)

In order to make the clothes have a white or bright appearance and a soft feel, they need to rinse the clothes, that is, after ordinary washing water, heating to 60 ° C, according to the depth of the bleaching color, add an appropriate amount of bleach (bleaching agent) In 7-10 minutes, the colors are consistent with the board. When operating, the direction of the drifting agent should be consistent with the steering of the rotary cylinder, so as to avoid bleaching agents directly falling directly on the clothing because it cannot be diluted with water as soon as possible, and local bleach appears. Before bleaching, the water level in the tank should be slightly higher to dilute water. After the clothing is bleached to the board, the residual bleaching water in the water is neutralized with large (small) soda (Na2CO3, NAHCO3) to completely stop the bleaching. After watering water, add washing agents, fluorescent whitening agents, hydrogen peroxide, etc. at 50 ° C water temperature, neutralized pH value, fluorescent white, etc., and finally soft treatment.

Rinse can be divided into oxygen and chlorine drift. Oxygen drift is to use the oxidation effect of hydrogen peroxide at a certain pH value and temperature to destroy the dye structure, thereby achieving the purpose of fading and adding whitening. Generally, the rafting surface will be slightly reddish. The chlorine drift is the purpose of destroying the dye structure with the oxidation effect of sodium hypochlorite, thereby achieving the purpose of fading. The fading effect of chlorine drift is rough, and is mostly used for rinsing in the orchid denim. After bleaching the board, the sea wave should be neutralized to the water in the water and the residues of the clothing to stop the bleaching. After the bleaching, the stone mill is called the bleach stone wash.

7. Destroy Wash

After the jacket is polished by the floating stones and the auxiliary treatment, it will cause a certain degree of damage in some parts (bone, collar, etc.). After washing, the clothes will have a more obvious disabled effect.

8. Snow Wash (Snow Wash)

Soak the dried floating stones with potassium permanganate solution, then directly polish with the clothing in the special rotary cylinder, polish it on the clothing through the floating stone, and use the potassium permanganate to oxidize the friction point, so that the cloth surface fades in irregularity, forming formation, forming formation, forming formed White dots like snowflakes.

The general process of snowflake washing is as follows:

Floating stones soak potassium permanganate -dried rocks and clothes -snowflake effects -remove the stone dust on the clothes in the water washing tank -oxalic acid neutralization -water washing -upper soft agent Essence

9. Moustache Effect is Whisker, but Whisker’s saying is professional. The cat’s beard is a type of hand sand (handbruky, hand brush), which is just grinding into the shape of the cat’s beard.

10. Sand spray is also known as sand stone was / sand blast. It is to use a large -scale toothbrush with a dedicated device (the image point is, but it is just a drum type) to polish the fabric. It is usually a combination of an inflatable model.

11. The difference between the essence of Monkey WASH and sand spray is the former as a chemical role, and the latter is a physical role. The spray horse is sprayed on the clothing according to the design requirements with a spray gun, and the chemical reaction occurs to make the fabric bleed. Use the concentration of potassium permanganate to control the degree of degeneration. If the effect is divided, the spray horse is uniform, and the inner layer of the surface is degenerate, and it can achieve a strong anti -color effect. Satsuch spray is only degenerate on the surface, and you can see the physical damage of the fiber.

12. Pigment WASH / Pigment Dyed Wash, also known as “single -sided coating / coating dyeing”, which means that this method of water washing is designed for dyed clothing, and its role is consolidating The original gorgeous color and the softness of increased feel

Fully -automatic direct -drive dehydrator: It uses semi -closed internal ventilation self -cold aggravated energy -saving motor to be installed in the middle base. Traditional multi -level tedious rotation, this machine is equipped with a frequency conversion of an electronic control box, the resistance brakes the speed display and adjustable speed and time. Water dehydration.

Snowframe: First mix the volcanic stone and potassium permanganate solution in the industrial washing machine to “fry” together, then put the clothes in and fry with the stone, then wash the clothes and remove the water

Relax of cowboy: Washing water, high temperature setting, local pressing, hand rubbing, tattered, hand -picked folds

Enzyme Wash (Enzyme Wash)

After curls, the treatment can make the printed paste, medicine and extraction base color clean. When washing hot water, it must be added to the dyeing agent JN to remove the yellow substance formed by the decomposition of the blue blue, and then it is well -boiled and hot water washed. The effect is better.

Hot water washing (50 ~ 60 ℃) upper axis → pure alkali washing (two soda 2g / L, two or above 80 ° C) → hot water washing (two or above 80 ° C) → soap boiling (90-95 ° C, soda 2 G / L. Clean washing agent 4g / L) → hot water washing (two two roads above 80 ° C) → cold water washing two lanes → upper axis → drying

3.5 Test color fastness

The coloring fastness of the elastic denim is dyed after staining and printed.

3.6 Precautions

3.6.1 Dip dye jn and citric acid must be separated separately. The pulled dye JN is dissolved with about 80c of hot water and mix it in the pulp. In addition, the citric acid is dissolved with cold water and then adds the slurry; the coatings and adhesives are finally added.

3.6.2 After steaming, wash a certain amount of pure alkali to make the yellow matter fall off quickly. Otherwise, the yellow matter formed on the cloth surface will not be removed. Essence

3.6.3 The fabric of the printing machine cannot be discovered intuitively, so it is necessary to steam with the seal and find the defects in time.

3.6.4 The color pulp is made to have a certain thickness, otherwise it will be created

The edge is unclear, affecting the cloth effect. The color paste is too thick, which is not conducive to penetration, and it is easy to cause the blue spots of the net. The color pulp is too thin, which is prone to flowing paste, forming white spots, and the outline of the flower type is not clear, produced by hair edges, and it is not cleaned.

3.6.5 Due to the difficulty of printing light -colored patterns on a deep background, it can be printed

Add 30 % white pulp to the flowers.
