What is Scouring spot?

Appearance: During the scouring process, the non-fibrous material in the scouring-dropped fabric is combined with the scouring agent, mixed with the fuzz from the fabric, and adheres to the surface of the fabric. There are irregular flaky yellow marks on the cloth surface. If you scrape it lightly with your fingernails, there will be short plush and debris falling off.

Cause:

1). The scouring agent is easy to coagulate at room temperature.

2). When scouring with a scouring kettle, the washing is not sufficient, or the washing temperature is low.

3). In continuous scouring, there are deposits in the scouring chamber, or there is too much foam in the scouring tank and the surface of the roll is unclean.
