Super Whitener created in China for acrylic fiber

Super Whitener created in China for acrylic fiber

As the No.1 manufacturer of optical brighteners in China, Zhejiang Hongda Chemical Co,.Ltd produce more than 30 kinds of optical brighteners for textile, detergent, plastic and paper industry (OB-1,CBS-X,OB,BBU etc).

Now I will introduce our latest “big bomb” in the market ---BAC for acrylic fiber.

Acrylic fibres is regarded as top 3 fibers for textiles with nylon and polyester fibres. Even normally acrylic fibers has good white degree, people need “bleach” it to meet higher requirement for whiteness. Scientists have done quite good job and there are several kinds of brighteners for acrylic in market, like C.I.363(UVITEX BAC),Blankophor ANB, Blankophor DBS,C.I.311(Hostalux NR), Blankophor DRS,C.I. 386(Hostalux NIR), Hostalux SN and C.I. 390(HostaluX SNR) etc.

Among them, the most popular is C.I.363 (UVITEX BAC) which is produced by Ciba(Note: Ciba sold its textile chemicals to Hustman chemicals later). Due to much difficulty in synthesis (11 steps), Ciba has occupied BAC exclusively for many years. No doubt, the price of BAC has been too expensive for most dye factories and limits its use in worldwide. Now it is time to change!

In 2007, With 4 years’ hard work, after thousands of failure, scientists from Hongda has finished the test in lab, medium-size production of BAC. Now commerical production of BAC is on schedule. After strict test, we are proud to announance that our BAC can completely substitute UVITEX BAC. Also, we are sure our price will be much lower than UVITEX BAC. We are honored to invite you to share the fruit with our company now. Pls check detailed information of BAC in the attachment.

More popular & important optical brighteners will be introduced in the future.


Best regards,

OB-1(C.I.393)


OB-1 is one of the most popular optical brightener now used in plastic products. It is famous for its high-resistance towards high temperature. Its melting point is 353—359°C and higher than other optical brighteners for plastic. OB-1 can be widely used for many plasstics, like PVC,PE,ABS etc. It can be added in many product using recycling materials and increase the white degree. Another big cusotmer is the manufacturer of polyester for textile industry. In China even one middle-size manufactuer of PE will use quite big quantity of OB-1.

OB-1 was firstly produced by Eastman company. Now there are many manufacturers supplying this product from many countries, like China,Korea,India etc. Even in China there are more than 10 manufacturers for OB-1. Because ther are at least 3kinds of synthesis method are using in these factories, the quality of product are quite different among these factoreis. Besides standard OB-1, there are many other types are produced to fulfill different need, like OB-1K for Polyester,OB-1P for masterbatch etc.

CBS-X

5% solution of CBS-X from Ciba and Hongda

CBS-X is produced firstly by Ciba and it is called "superstar of OBA" because of its excellent effect in detergent. Now it is produced by many other manufacturers, like Zhejiang JDR ,Hongda, Dystar etc. For this product, it has different trade name, like Tinopal CBS-X, Uvitext NFW, JDR CBS-X etc.

Besides widely using in detergent, CBS-X also has been applied into textile industry, especially cotton. However, its high price has prevent its market role before. With tenichique development, more and more Chinese manufacturers push their CBS-X into market with price much lower than old manufactuer like Ciba and Dystar. Good quality and much lower price, CBS-X from China has defeated many big company's CBS-X. It is no doubt that China CBS-X will gain more market share if big company can not sort out good means to compete with these strong pursuer.
