The main difference is the way of weft insertion.
1. The shrinkage rate of these three models is generally similar because their weaving tension is relatively large.
2. As long as there is no problem with the yarn and the weaving shaft in terms of production efficiency, the air jet is definitely better than the rapier. All types of the jet can basically be used on rapier, but for jacquard, multi-color weft (more than four colors) has higher requirements for jet, the jet has sixteen-page heald jacquard, dual-axis configuration, and six-color weft selection.
3. The rapier loom can make heavier fabrics. The same material can be made by air-jet and rapier, and the weaving effect of the air-jet loom will be better.
Extended information:
1. Rapier loom: the most widely used shuttleless loom at present. In addition to the characteristics of high speed, high automation, and high-efficiency production of shuttleless looms, its active weft insertion method has strong variety adaptability. It can adapt to the weft insertion of various yarns, and the rapier loom also has obvious advantages in multi-color weft weaving and can produce yarn-dyed products with up to 16-color weft yarns. With shuttleless looms replacing shuttle looms, rapier looms will become the main production machine for woven fabrics.
2. Water jet loom: a shuttleless loom that uses jet water to pull the weft through the shed. The frictional traction force of water jet weft insertion on weft yarn is larger than that of air-jet weft insertion, and the diffusivity is small, which is suitable for the needs of weft insertion of filaments such as synthetic fibers and glass fibers with a smooth surface. At the same time, it can increase the electrical conductivity of synthetic fibers and effectively overcome the static electricity in weaving. In addition, jetting weft yarn consumes less energy and has the lowest noise.
3. Air-jet loom: a shuttleless loom that uses jet air to pull the weft through the shed. The working principle is to use air as the weft insertion medium and use the jetted compressed airflow to generate frictional traction on the weft yarn to pull the weft yarn through the shed and achieve the purpose of weft insertion through the jet generated by the air jet.
