Garment wash is to put the manufactured jeans into the machine for ordinary washing, which is similar to washing clothes at home but it's mechanized. Generally, we set the water temperature at about 35°-45°C when make garment wash, then add a certain amount of washing powder or laundry liquid, the washing time is about 15 minutes, and then wash the clothes with clean water and add some softener.


Stone wash is to make the denim garments textured and rough, it is necessary to do stone wash, that is: add a certain size of pumice stone to the washing washing machine. The pumice stone is divided into yellow stone and white stone. When make stone wash, the water level should be low at where the clothing is fully saturated so that the pumice stone can make good contact with denim. According to different customers' requirements, the amount of stones can be appropriately increased or decreased to achieve different washing effects.


Enzyme is a kind of cellulase, which can degrade the fiber structure under a certain PH value and temperature, so that the cloth surface can be gently faded, and can make the denim surface look more durable and soft. However, the color cannot be made very light. To achieve light wash denim, bleaching is necessary. The ensyme wash can be used together with stones, which is usually called enzyme stone wash.


When make sand wash, we often use some alkaline and oxidizing auxiliaries to make the clothes have a certain fading effect and old feeling after washing. We will determine the appropriate sand washing agent, concentration, temperature, and sand washing time according to the type of fiber, the tightness and structure of the fabric, etc.


In order to make the denim have a white or bright appearance and soft hand feel, the garment need to be bleached, that is called bleach wash. After an ordinary wash, heat the water to 60°C and add some bleach to the water as needed. When doing a bleach wash, compare the color with the correct sample every 5 minutes until the color is the same as the sample.


ACID washed jeans: that have some of the pigment removed, come in different colors, and are made in a few different ways. Put the jeans in the washing machine and turn it on, then continiously put the proportioned potassium manganate and water into the washing machine in a funnel way. This irregular and even dipping on denim, make it irregular faded looking.

In addition, denim needs to do other crafts before or during the washing process. Such as: Destroy Craft, Monkey Wash, Moustach Effect, 3D Wrinkles, etc.
