Little Knowledge: Knowledge Of Trademarks, Water Marks And Water Washing

< p > 1. GARMENT WASH common cleaning, namely, ordinary a href= "http://www.91se91.com/" > washing > /a >, only turn our familiar washing to mechanization. Its water temperature is about 60 degrees -90 C, plus a certain detergent. After 15 minutes of Zuo Youpu washing, it can soften and soften the fabric with more softness and softness, and make it more natural and cleaner in vision.

Generally, according to the length of washing time and the amount of chemicals, general washing can be divided into light washing, general washing and heavy washing.

Usually, it takes about 5 minutes to wash light and wash for about 15 minutes, and then to wash for 30 minutes. This time is not accurate. There is no clear boundary between these three methods.

< p > 2, stone washing (STONE WASH) stone washing means adding a certain amount of pumice in the washing water to make the pumice and the clothes polished. The water level in the grinding cylinder is carried out at low water level which is completely saturated with clothes, so that the pumice can well contact with the clothes.

It can be washed or rinsed before the stone grinding, and can be rinsed after the stone grinding.

According to the different requirements of customers, Huangshi, white stone, AAA stone, artificial stone and rubber ball can be washed to achieve different washing effect. After washing, the cloth surface is gray and old, and the clothing has slight to severe damage.

< p > 3, ENZYME WASH enzyme is a cellulase which can degrade the fiber structure at a certain pH and temperature. It can make the cloth fade and fade gently (producing peach peel effect) and obtain a lasting soft effect.

It can be used as stone or substitute for stone. If it is used with stones, it is usually referred to as < a href= "http://www.91se91.com/" > enzyme stone wash > /a > (ENZYME STONE WASH).

< p > 4, sand washing (SAND WASH) sand washing, and using alkaline oxidizing aids to make the clothes have certain fading effect and obsolete feeling after washing. If the stones are mixed with the stone, the surface of the cloth will produce a layer of soft frost and white fur, and then add some softeners to make the washed fabrics soft and soft, so as to improve the comfort of the clothes.

(1) sand washing agent a) puffing agent: according to the type of fiber, fabric structure and tightness, the expansion agent and concentration, temperature, time and other expansion conditions are selected. When washing pure cotton clothes, puffing agents such as soda ash can be used for expansion treatment.

B) sand lotion: after puffing, the fabric is loose, and then it is used to rub the special sand to make the loose surface fiber produce full and soft fuzz. To make the suede plump, it is necessary to use different forms and different hardness of sand powder, such as the choice of diamond sand (loose fiber to produce fluff), polygonal sand (make the upright erect), round sand (make the fluff full).

C) softener: Softener used for sand washing.

Soft and waxy properties are required to increase weight and drape of fabrics.

Therefore, this kind of softener has long carbon chain, and has a cationic nature, which can adsorb on the fabric and achieve the purpose of gaining weight.

(2) sand washing equipment is generally used in industrial washing machines for puffing, sand washing and softening treatment, centrifugal pump dehydrator dehydration, drying drying machine using rotary drying machine.

(3) sand washing process cotton cloth can be determined according to the organization structure, the density of the warp and weft, the thickness and twist of the yarn, the type, dosage, temperature and time of the expanding agent, as well as the amount of sand washing agent, softener and the temperature and time. In general, the choice of yarn fabric is better than that of the thread fabric, the coarse yarn is better than the high count yarn, the low twist is better than the high twist, and the floating point length is better than the floating point short product.

< p > 5. chemical washing (CHEMICAL WASH) chemical washing is mainly achieved through the use of strong alkali auxiliaries (NaOH, NaSiO3, etc.) to achieve the purpose of fading, washing clothes have a more obvious sense of obsolescence, and then add softeners, clothing will be soft and full effect.

If you add stones into chemical washing, it is called CHEMICAL STONE WASH, which can enhance the effect of fading and abrasion, so that the clothing has a strong sense of residue. The effect of fossilized washing and chemical washing and stone washing can be achieved in one body. After washing, it can achieve a kind of effect of imitation and fuzzing.

< p > 6. < a href= "http://www.91se91.com/" > rinse > /a > (BLEACH WASH) rinse can be divided into oxygen bleaching and chlorine bleaching.

Oxygen bleaching is the use of hydrogen peroxide at certain pH value and temperature to destroy the structure of the dye, so as to achieve the purpose of fading and whitening. The surface of ordinary bleaching will be slightly red.

Chlorine bleaching is the use of sodium hypochlorite oxidation to destroy the structure of dyes, so as to achieve the purpose of fading.

The bleaching effect of chlorine bleaching is rough, and is often used for rinsing indigo denim.

After bleaching the plate, the sea water should be neutralized with residual chlorine in the water and clothing, so that the bleaching will stop. After bleaching and then grinding, it will be called BLEACH STONE WASH.
