classification

There are many classifications for loom. According to the classification of fabric fibers, it can be divided into cotton textile machines, wool textile machines, sack looms, silk looms and the like. For example, according to the weft insertion method of weaving, it can be divided into two categories: shuttle looms and shuttleless looms.

The shuttle loom is a weaving machine that uses a conventional shuttle (wood shuttle or plastic shuttle) to weft. The shuttle has a large volume and a heavy weight, and is repeatedly projected by the vehicle. The machine has large vibration, high noise, slow speed and low efficiency.

The weft insertion method of the shuttleless loom is various, including rapier, jet (jet, water spray), gripper, multi-shed (multi-phase) and weaving.

1. Rapier loom: Use a rigid or flexible rapier head to bring the grip and guide the weft. In addition to being suitable for weaving plain and textured fabrics, rapier looms are characterized by easy color change and suitable for multi-color weft fabrics, suitable for the production of yarn-dyed, double-layered velvet fabrics, terry fabrics and decorative fabrics.

2. Air jet loom: The weft yarn is pulled by the jetted compressed air stream, and the weft yarn is taken through the shed. The most important feature of air jet loom is its high speed and high labor productivity. It is suitable for the production of plain and textured fabrics, fine high-density fabrics and large-volume fabrics.

3. Water jet loom: Using water as the weft insertion medium, the jet water flow generates friction traction force on the weft yarn, so that the weft yarn on the fixed bobbin is introduced into the shed. The water jet loom is characterized by high speed and high unit yield, and is mainly suitable for the production of hydrophobic filament chemical fiber fabric with smooth surface.

4. Projectile loom: The weft yarn is clamped by a small piece of shuttle with a clip to project the weft insertion. The projectile weaving machine has the advantages of stable weft insertion, excellent fabric quality and less weft yarn, and is suitable for the production of multi-color weft fabrics, fine, thick fabrics and wide fabrics.
