1, the things added in the water are different.

Water washing is to add softener or detergent to the water and directly water the fabric once. The process of sand washing is actually similar to water washing, but the added things are different. Generally, alkaline or oxidizing additives will be added, and of course, some softeners will be added in moderation.

2. The washing time is different.

According to the washing time and the amount of softener, it is generally divided into light general washing, general washing and heavy general washing. Sand washing time is generally longer than water washing time.

3, the effect is different.

The effect of washing is that the fabric will become very soft and feel good, and there will be an illusion that the fabric will become thicker. The purpose of adding alkaline additives is to destroy the texture of the fabric surface and make the fabric feel softer after sand washing, and then some fluff and faint white fog will appear on the fabric surface. Therefore, the fabric will become soft and fluffy after sand washing, and the fabric will have an illusion of thickening. However, this kind of fabric is easy to crack and may break with a light pull. We generally don't recommend sand washing for thin fabrics.
