Multi-purpose sheath-core composite monofilament as well as production method and application thereof

Abstract

The invention relates to a multi-purpose sheath-core composite monofilament for weaving reticulated as well as a production method and application thereof, and belongs to the technical field of production of composite fibers. The multi-purpose sheath-core composite monofilament comprises a sheath layer and a core layer, wherein the sheath layer covers the core layer; the core layer is prepared from PP, TPU or TPEE; the sheath layer is prepared from PE, POE, TPU or TPEE; the melting point of the sheath layer is 120 to 170 DEG C; the melting point of the core layer is 150 to 210 DEG C; the content of the sheath layer is 30 to 70 percent; the content of the core layer is 70 to 30 percent. The multi-purpose sheath-core composite monofilament comprising two components can be applied to weaving of gauze, window screens, curtains, abat vents, light equalization cloth, anti-mosquito nets, anti-haze gauze, filter screen cloth, shoe screen cloth, and base materials of power transmission belts.

Description

technical field [0001] The invention relates to a multi-purpose skin-core composite monofilament and its production method and application, which relate to a skin-core composite monofilament that can be used for weaving mesh fabrics, and belong to the technical field of composite fiber production. Background technique [0002] In traditional mesh fabrics (filters, screens, curtains, shoe nets, etc.), glass fibers, yarns or single fibers are used for weaving. [0003] For example, the glass fiber raw material is first drawn, and then the drawn surface is coated with plastic, and then the net is woven into a net by a shuttleless loom and then subjected to a high-temperature setting machine to obtain a high-stability window screen. Plastic processing, the processing technology is complex, and glass fiber products are difficult to recycle; patent CN201210274327.9 directly coats polyester filaments, twists directly through polyester filaments → monofilament plastic coating → wa...

[0003] For example, the glass fiber raw material is first drawn, and then the drawn surface is coated with plastic, and then the net is woven into a net by a shuttleless loom and then subjected to a high-temperature setting machine to obtain a high-stability window screen. Plastic processing, the processing technology is complex, and glass fiber products are difficult to recycle; patent CN201210274327.9 directly coats polyester filaments, twists directly through polyester filaments → monofilament plastic coating → warping → weaving → shaping → cloth inspection , the prepared 20×20 mesh polyester plastic-coated window screen with high fabric clarity and a square meter weight lower than 85g/m2. This method is a meth
