Fire Resistant Modacrylic Yarn

　

1. We can supply single or two-fold yarn. The yarn count is 5,7,10,16,30 and 32. But also bunchy yarn may be obtained. It is mono-fiber yarn(namely 100% fire resistant acrylic fiber). As for quality index, for example twist, evenness, fuzzy fiber and so on, we will supply goods by user requirement.

　

2. We can supply rotor spun modacrylic yarn. The count of our sample available is 5, 7, 10, 16, 20, 24, 26, 30 and 32. But also bunchy yarn may be obtained. They are mono-fiber yarn(namely 100% fire resistant acrylic fiber).

　

3. We can supply modacrylic yarn blended with polyester fiber, cotton and viscose. Samples will be available soon.

　

4. The difference of fire resistant acrylic fiber and high fire resistant ones lies in LOI(Limit oxygen Index). The LOI of the former is more than 27, while the LOI of the latter surpasses 30(include 30).
