Abstract

The invention discloses a carding device for preparing p-aramid fiber yarns. The carding device comprises a cotton box, a cotton conveying roller, an inclined pallet, a horizontal pallet, a cotton feeding roller and a carding machine, a horizontal pressing plate parallel to the horizontal pallet is arranged above the horizontal pallet, a plurality of air flow sprayers are arranged in the horizontal pressing plate, a plurality of flow adjusting rotating spoons which are sequentially arranged are disposed between the air flow sprayers and the horizontal pallet, the flow adjusting rotating spoonsand the air flow sprayers are vertically arranged in a one-to-one corresponding manner, and each of the flow adjusting rotating spoons comprises a fixedly rotatable cylinder and a rotatable concave spoon which are connected with each other. According to the carding device, electrostatic removal effects are good, rigidity of the yarns can be reduced, smoothness of a cotton layer can be increased,adjustability is high, and treating efficiency is higher.

Description

technical field [0001] The invention relates to a weaving process for 1414 yarns, which belongs to the technical field of textiles, and in particular to a carding device for preparing para-aramid yarns and a use process thereof, which are particularly suitable for enhancing the effect of removing static electricity and reducing the stiffness of the yarns. Background technique [0002] The chemical name of aramid 1414 is poly-p-phenylene terephthalamide. It is a new high-tech synthetic fiber with excellent properties such as ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, and light weight. The specific strength of aramid fiber 1414 is 5-6 times that of steel, the modulus is 2-3 times that of steel or glass fiber, the toughness is 2 times that of steel, and the quality is only one-fifth of steel. The lower shrinkage rate is zero, it does not decompose below 560°C, and its glass transition temperature is above 300°C. It has good adhes...
