Applied to multi-axial warp knitting equipment flattened carbon yarn twistless interlining system

Abstract

The invention relates to a flattened carbon yarn twistless laying-in system applicable to multiaxial warp knitting equipment, comprising a yarn reversal device and a weft laying-in device; the weft laying-in device is disposed at the front end of the yarn reversal device. Pneumatic-electric sensing combined grating and digital signal processing control are fitted to the movement of the flattened carbon yarn twistless laying-in apparatus sensing the whole multiaxial warp knitting equipment. The mutual sensing of a convex stepped creel in the yarn reversal device, the yarn reversal device and a tension device not only narrows the gaps among the flattened carbon yarns unwinded from the creel, and but also maintain uniform tension for carbon yarns; an angle rack and a controller in the weft laying-in device convey the flattened carbon yarns and also promote further uniform distribution of tows, keeping the uniform width of the flattened carbon yarns and keeping them twistless and free of abrasion and other defects, the flattened carbon yarns are maintained uniform in tension and low in gap rate, and therefore, the multiaxial warp knitting equipment can produce multiaxial fabric with less density and smaller thickness.

Description

technical field [0001] The invention relates to the field of textile high-performance fiber weaving machinery, in particular, to a non-twisted carbon yarn interlining system applied to multi-axial warp knitting equipment, which is applied to multi-axial warp knitting equipment to flatten carbon yarn without twist The lining system effectively solves the research and development problems of new products, and has strong practicability, wide adaptability, strong operability, and meets the development concept of scientific innovation. Background technique [0002] Multiaxial warp knitted fabric is currently the most pre-designed reinforced material structure, and its weaving technology is also changing with each passing day as the performance requirements of composite materials are improved. Especially for carbon fiber multiaxial fabrics, the trend is towards thinner and lighter. In most cases, carbon fiber is a non-twisted yarn. It is a filament yarn composed of many monofilam...
