There are four categories: (1) Full -pair -pair -pair -pair -pair -pair -pair -pair -pair -galmide cluster fiber; (3) Full -bonuscanamide fiber; (4) Essence The first two categories are high -strength and high -profile heat -resistant fibers, and the latter two are high -temperature resistant and difficult to ignite fiber.
The method of system uses a low -temperature solution for retracting. Among them, the (1) class is to separate the polymer and dissolve in the concentrated sulfuric acid dry spray wet spray. If necessary, it can be treated. Separate polymer, and then dissolve the spinning, and directly wet the wet wet and stretching by (3) and (4).
The use of (1) and (2) is used to use the use of high -strength and high -mode performance at room temperature and high temperature at room temperature and high temperature.
