Many people who don’t understand denim are curious that there are so many different colors of fabric effects, but denim actually only has the most classic denim blue, black, and gray, and the denim fabric surface is very smooth and not tattered, while denim can be tattered. , with different patterns. How do you achieve such a beautiful effect on denim clothing?

It is because jeans garment factory makes different washing processes on the denim jean clothing.

Now we are introducing the common denim washing process. With the development of denim, people are no longer satisfied with the simple denim style. Because of the upgrade of the washing process, the style of jeans has become richer.

What are they? Normal washing, Stone wash, Enzyme Wash, Sand Wash, Chemical Wash, Bleach Wash, Destroy Wash, snowflake wash, Whisker, Spray stone wash / Sand Blast, Monkey Wash, Pigment wash / pigment dyed wash

01 Normal washing

Denim or selvedge denim fabric General washing means ordinary washing. It just changes the washing we are familiar with to mechanization. The water temperature is around 60°-90°C. Add a certain amount of detergent. After about 15 minutes of ordinary washing, add water and softener to soften the fabric. Softer, more comfortable, visually more natural and cleaner. Usually, based on the length of washing time and the amount of chemicals used, general washing can be divided into light general washing, general washing and heavy general washing. Usually light general washing lasts about 5 minutes, general washing lasts about 15 minutes, and heavy general washing lasts about 30 minutes. (This time is not precise). There is no obvious boundary between these three washing methods.

02 Stone wash

Stone washing is to add a certain size of pumice stone to the washing water to polish the pumice stone with the clothes. The water level in the polishing tank is set to a low level where the clothes are completely soaked, so that the pumice stone can blend well with the clothes. touch. General washing or rinsing can be carried out before stone grinding, and rinsing can also be carried out after stone grinding. According to the different requirements of customers, yellow stone, white stone, AAA stone, artificial stone, rubber balls, etc. can be used for washing to achieve different washing effects. After washing, the cloth surface will appear gray and old, and the(selvedge/selvage) denim jeans pants,shorts,dress,shirts,jackets ect will be slightly to severely damaged.

03 Enzyme wash

Enzyme WASH enzyme is a kind of cellulase, which can degrade the jeans fabric fiber structure under a certain pH value and temperature, so that the denim fabric surface can fade and remove hair more gently (producing a “peach skin” effect) , and get long-lasting softness. Stones can be used together with or instead of stones. If used together with stones, it is usually called ENZYME STONE WASH.

04 Sand wash

Sand washing uses some alkaline and oxidizing additives to make the denim jeans material have a certain fading effect and a sense of staleness after washing. If it is combined with stone grinding, a layer of soft, frosty white fluff will be produced on the surface of the denim fabric after washing, and some softeners will be added. It can make (selvedge/selvage) denim fabrics soft and soft after washing, thereby improving wearing comfort.

05 Chemical wash

Chemical washing mainly uses strong alkali additives (NaOH, NaSiO3, etc.) to achieve the purpose of fading. After washing, the clothes will have a more obvious stale feeling. Adding softeners will make the jeans jacket etc soft and plump. If stones are added to chemical washing, it is called fossil washing (CHEMICAL STONE WASH), which can enhance the fading and wear effects, making the clothes have a strong sense of distress. Fossil washing combines the effects of chemical washing and stone washing. After washing, it can achieve an imitation and fluffing/neppy effect.

06 Bleach wash

Rinse (BLEACH WASH) In order to make the clothes have a white or bright appearance and a soft feel, the clothes need to be rinsed. After ordinary washing in clean water, heat it to 60°C. Add an appropriate amount of bleach according to the depth of the bleached color. (bleaching agent), make the color consistent with the board within 7-10 minutes. During operation, the direction of adding bleach should be consistent with the direction of the rotating cylinder to prevent the bleach from falling directly on the clothes because it cannot be diluted with water quickly, causing partial bleaching. Before bleaching, the water level in the tank should be slightly higher to facilitate dilution of the bleaching water. After the clothes are bleached, use large (baking) soda (Na2CO3, NaHCO3) to neutralize the residual bleach in the water to completely stop bleaching. After washing with clean water, add detergent, fluorescent whitening agent, hydrogen peroxide, etc. to the water at 50°C for final washing, neutralizing the PH value, fluorescent whitening, etc., and finally softening.

07 Destroy wash

DESTROY WASH: After pumice polishing and additive treatment, the garments will have a certain degree of damage in certain parts (bones, collar corners, etc.), and the clothes will have a more obvious dilapidated effect after washing.

08 Snowflake wash

For snowflake washing, the dry pumice is soaked with potassium permanganate solution, and then polished directly with the clothes in a special rotating cylinder. The pumice is polished on the clothes so that the potassium permanganate oxidizes the friction points and makes the cloth surface irregular. Fades, forming white spots that resemble snowflakes.

The general process of snowflake washing is as follows: Soak pumice in potassium permanganate – Dry grinding of pumice and clothes – Check the snowflake effect – Take out the clothes and wash off the stone dust on the clothes with clean water in the washing tank – Neutralize with oxalic acid – Wash with water – Apply softener.

09 Whisker

MOUSTACHE EFFECT is WHISKER, but WHISKER is more professional. Cat whiskers are a type of hand sand (HAND BRUSH), which is just ground into the shape of cat whiskers.

10 Spray stone wash / Sand Blast

Sand blasting, also known as SPRAY STONE WASH / SAND BLAST, uses special equipment (a kind of large electric toothbrush, just a roller type) to polish the cloth, usually with an inflatable model.

11 Monkey wash

The essential difference between MONKEY WASH and sandblasting is that the former is a chemical effect, while the latter is a physical effect. Spray maliu is to use a spray gun to spray potassium permanganate solution onto the clothing according to the design requirements, causing a chemical reaction to cause the denim fabric to fade. Use the concentration and spray volume of potassium permanganate to control the degree of fading. In terms of effect, Spray Maliu fades evenly, with both the surface and inner layers fading, and can achieve a strong fading effect. Sandblasting only causes fading on the surface, and physical damage to the fibers can be seen.

12 Pigment wash

Pigment wash/pigment dyed wash is also called “single-sided coating/pigment dyeing”, which means that this washing method is specially designed for garments that have been dyed with pigment. Its function is to consolidate the original gorgeousness. Color and softness to the touch.
