Abstract

The invention discloses a rapier head for a rapier loom, which is composed of the following components in parts by weight: 60-80 parts of polyformaldehyde, 10-15 parts of aramid fiber, 5-10 parts of polytrimethylene terephthalate, 5-8 parts of polyolefin elastomer, 3-4 parts of ethylene-vinyl acetate copolymer, 1-3 parts of silane coupling agent KH550, 4-6 parts of calcium carbonate whisker, 1-3 parts of nano silicon dioxide and 1-2 parts of anti-aging agent nickel dibutyldithiocarbamate. The preparation method comprises the following steps: compounding an engineering plastic with other reinforcing materials, and blending and granulating through a double screw extruder; and molding the prepared composite material through an injection molding machine to obtain the rapier head.

Description

technical field [0001] The invention relates to the field of rapier looms, in particular to a rapier head for a rapier loom and a preparation method thereof. Background technique [0002] The new shuttleless loom has become the development direction of the world's textile machine industry. The development of the loom from shuttle to shuttleless has greatly improved the efficiency of weaving. The rapier loom is the most widely used shuttleless loom at present, and the rapier head is an important component in the weft insertion mechanism of the rapier loom, and its performance is directly related to the quality of the fabric and the production efficiency of the loom. Sword heads are expensive consumables, and frequent replacement will undoubtedly increase the cost of weaving. The material used for this part needs to be light and wear-resistant, yet sufficiently strong. CN101760865A discloses a rapier loom head made of carbon fiber reinforced nylon 66 composite material and i...
