Cellulosic Scouring Is A Technology To Popularize Cellulose Fiber Scouring.

< p > a href= "http://? www.91se91.com/news/index_c.asp" > cellulose < /a > fiber is used as raw material to produce nonwovens after scouring and bleaching. It is not only clean in appearance but also high in whiteness, and its water absorption, wettability, softness, and absorption and utilization of fuel and finishing agent will change greatly.

In particular, scouring and bleaching are of great significance for the production and development of nonwovens sanitary materials.

< p > refining by using < a href= "http:// www.91se91.com/news/index_c.asp" > enzyme < /a > will not only affect the skeleton of cellulose, but also reduce the damage to the surface of non-woven fabric to a minimum.

If the enzyme is scoured, stirring can improve the wool effect of nonwovens.

< p > cotton fiber is a natural cellulose fiber commonly used in nonwovens. The content of natural impurities in cotton fibers depends on the origin, maturity and other factors of raw cotton.

The purpose of scouring is to remove natural or man-made impurities in fibers, such as waxy substances on natural cotton fibers, and the remaining spinning oil and oil stains on synthetic fibers can also be removed after scouring.

< p > scouring can significantly improve the wetting and water absorption properties of < a href= "http:// www.91se91.com/news/index_c.asp" > nonwoven fabric < /a >, improve the appearance quality of the products, and also prevent the interference of these impurities to dyeing and finishing process.

< /p >

< p > because nonwovens themselves are not suitable for scouring and finishing of conventional fabrics after dyeing and finishing, the method of bulk fiber processing is usually used when products need to be scoured.

< p > during the scouring process, the temperature required by the process is greater than or equal to 100 degrees C. if the equipment is allowed, it is best to use 120 ~130 C. Only this kind of scouring condition can remove the impurities in the fiber and ensure good water absorption.

When the dosage of scouring agent is constant, increasing the scouring temperature is conducive to the removal of impurities and shortening the boiling time. On the contrary, the temperature is low and the boiling time is long.

< p > biological enzyme scouring is a technology of cellulose fiber scouring and processing which is being vigorously promoted.

During the traditional scouring process, a large amount of clean water will be consumed after scouring to produce a large amount of sewage, which will have a great impact on the environment. However, using biological enzyme refining method can not only effectively remove impurities, but also greatly reduce environmental pollution.

< /p >

< p > refining with enzyme not only will not affect the skeleton of cellulose, but also reduce the damage to the surface of non-woven fabric to a minimum.

Proper mixing method can play a positive role in scouring effect.

If stirred in the process of enzyme scouring, it can shorten the time and reduce the amount of enzyme, and also improve the wool effect of nonwovens.
