Description
Technical field
The utility model relates to a kind of core-skin composite fiber equipment, particularly relates to a kind of ultrahigh molecular weight polypropylene and ultra-high molecular weight polyethylene core-skin composite fiber equipment.
Background technology
Superhigh molecular weight polyethylene fibers temperature tolerance is low, and when using under higher temperature, the mechanical performance index such as intensity, modulus significantly reduces, the fibre lost of life.Due to superhigh molecular weight polyethylene fibers interior molecules, mechanism presents extended-chain configuration, and the creep of this fiber at certain temperature and external force is obviously increased.When the inner molecular structure of high-sequential and non-polar nature cause this fiber to use as composite raw fiber, not good with the interface adhesion of resin matrix.Such as, the shock resistance of the anti-spring-go material of superhigh molecular weight polyethylene fibers is inadequate, and therefore, the above-mentioned defect of superhigh molecular weight polyethylene fibers, causes the product such as bullet resistant material, hawser to have certain defect.
Composite fibre refers to by two or more polymer, or the chemical fibre that the method with same polymer employing composite spinning of different nature is made, containing two or more immiscible component on the cross section of fiber.Divide according to structure, common composite fibre has parallel type, core-skin type, fabric of island-in-sea type, sliver type etc.
