Hebei Ning Textile Was Re Invented Patent

< p > recently, < a href= "//www.sjfzxm.com/news/index_c.asp" > Ningbo Textile > /a > group a low-temperature scouring and bleaching agent and its application technology were awarded the invention patent certificate by the State Intellectual Property Office.

< /p >

< p > it is reported that the patented technology can be applied to < a href= "//www.sjfzxm.com/news/index_c.asp" > printing and dyeing enterprise < /a > < a > href= > //www.sjfzxm.com/news/index_c.asp > pretreatment process < /a >, which can improve the traditional high temperature and high alkali scouring and bleaching process to a process of low temperature, less alkali, boiling and bleaching, making the production process more energy saving and environmental protection, and optimizing the pretreatment effect of cotton and its blended fabric at the same time.

< /p >

< p > > according to the responsible person in charge of the enterprise, Ning Ning has 4 national patents, of which two are patents of invention and utility models.

After P and cellulose fibers are used as raw materials, nonwovens can be cleaned and whitened after being scoured and bleached, and their water absorption, wettability, softness, and absorption and utilization of fuel and finishing agents will be greatly changed.

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

< /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.

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

< /p >

< 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 >

< p > scouring can significantly improve the wetting and water absorption properties of nonwovens, improve the appearance quality of products, and prevent the interference of these impurities to dyeing and finishing processes.

< /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 >

< 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.
