Background
The inorganic fibers comprise basalt fibers, alumina fibers, carbon fibers, inorganic alkali-resistant glass fibers, quartz fibers, ceramic fibers and the like, and have the common characteristics of high temperature resistance, corrosion resistance and the like. The basalt is formed by cooling volcanic eruption magma, raw materials are purely natural, the yield is relatively rich, but the preparation difficulty of basalt fibers is high, the working procedures are multiple, and the specific production steps comprise raw material preparation, melting, wire drawing and the like. Basalt fibers belong to inorganic materials and have the excellent performances of light weight, high strength, high temperature resistance, corrosion resistance, oxidation resistance, impact resistance, radiation resistance, heat insulation, sound insulation, non-magnetism, wave permeability and the like; but basalt fibers are high in rigidity, easy to break, low in elongation at break and low in elasticity, and the manufactured yarn and the fabric thereof are hard in handfeel, more in burrs and large in itching, and the basalt fibers are easy to break, drop and low in stability during bending, friction and kneading. Especially basalt fibers are high in brittleness and poor in wear resistance, are easy to break in the yarn forming process, and are easy to generate burrs due to poor wear resistance in the subsequent processing and weaving process, so that the weaving efficiency and the wearing and wearing properties of the end fabric product are greatly reduced. Therefore, the characteristics of heat insulation, fire resistance, flexibility, wear resistance, skin comfort and the like of basalt fiber yarns and fabric products thereof are simultaneously and efficiently realized, the market demand is urgent, and the technical difficulty is high.
The patent with publication number CN104191737B discloses a preparation method of special composite fabric based on flame-retardant basalt fiber, wherein basalt fiber is woven into basalt fiber fabric with a plain weave or twill weave structure in a weaving mode, and then the basalt fiber fabric is composited with other fabrics through an organic adhesive. The special composite fabric prepared by the method only adopts an organic adhesive to coat, basalt fibers are easy to slip due to coating, and the special composite fabric has extremely poor stability, low production efficiency and narrow application range in the processing process. The patent with publication number CN102154753a discloses a basalt core spun yarn, which is formed by directly cladding basalt fiber into yarn, but because basalt fiber is still broken in the yarn body in the subsequent fabric use, there is still the risk of falling off and running to the yarn body or the fabric surface.
Therefore, how to completely overcome the problems of the basalt fiber core-spun composite yarn and the basalt fiber fabric, such as fracture and twist off exposure risk, poor stability, low uniformity, low strength and the like of the basalt fiber after multiple bending, comprehensively and efficiently realize the heat insulation fireproof, flexible wear-resistant and skin-friendly comfort characteristics of the basalt fiber composite yarn and the basalt fiber fabric, and the steps of filament processing, filament core-spun composite spinning, twisting, mixed weaving and the like of the basalt fiber are required to carry out systematic collaborative innovation.

As can be seen from table 1, in comparative example 1, when basalt multifilament is not twisted and is directly used as a coaxial spinning core wire, the abrasion resistance of the fabric is deteriorated, since basalt multifilament is not twisted, the cohesion between fibers is small, the relative slip is easily generated, the breakage is more easily caused, and the TPP value and the air permeability are slightly lowered; in comparative example 2, the vortex spinning process is not adopted to prepare the covering yarn, the wear resistance of the prepared fabric is reduced, and the basalt fiber is exposed and directly contacts with the outer surface, so that the fabric is more fragile and burrs are generated to cause the wear resistance of the fabric to be poor; the air permeability is slightly reduced, and the contact between the weft yarns is tight due to the fact that vortex spinning cladding fibers are not adopted, so that the air permeability is affected to a certain extent; TPP value is reduced, and heat protection performance is reduced due to the fact that vortex spinning is not adopted to wrap flame-retardant fibers; the core-spun fabric prepared in comparative example 3 is not subjected to friction spinning, the outer wrapping filaments and basalt filaments are exposed, the wrapping of the skin-friendly fibers is lacking, so that the basalt filaments cannot be fully wrapped on the core layer, the wear resistance is poor, the TPP value is obviously reduced, the skin-friendly fireproof fibers wrapped by the friction spinning are lacked in the same way, the heat protection performance is poor, and the air permeability is reduced because the warp yarns are not subjected to friction spinning wrapping fibers, so that the contact between the warp yarns is tight, and the air permeability is reduced; in the comparative example 4, the abrasion resistance of the obtained fabric is greatly reduced by directly adopting the core-sheath structure composite yarn without wrapping the filaments by using the hollow spindle, and the abrasion resistance of the yarn is poor due to the fact that the abrasion resistance of the fabric is poor due to the fact that the abrasion resistance of the yarn is not introduced; the TPP performance of the fabric is also affected to a certain extent, and the heat protection performance is also deteriorated when the filaments are not introduced because the filaments are also selected to have flame retardant performance; meanwhile, the air permeability of the fabric is also affected, filament wrapping is absent, the yarn structure is high in fluffy hairiness, gaps on the fabric are reduced, and the air permeability is poor.
In summary, the invention develops the combined spinning technology of friction spinning, ring spinning, hollow spindle spinning and coaxial wet spinning technology, so that the prepared fabric has ten-thousand wear resistance, and can improve the thermal protection performance and air permeability of the fabric.
