▲Rapier loom
▲Air jet loom
Fabric distinction:
To determine whether a fabric is a sword-woven fabric or an air-jet fabric, you can look at the edge organization of the fabric:
(1) Usually the polyester-cotton thread is rapier (semming device), and the filament is air-jet weaving (planetary gear device).
(2) Air-jet double-open fabric, one side is thread and the other side is filament. (The middle is a locking device, and both sides have weft planetary gears.
(3) Rapier double-open fabric, the side yarns on both sides are polyester-cotton threads (both are hemming devices).
Loom distinction:
Rapier loom:Use rigid or flexible rapier heads and belts to clamp and guide the weft yarn. In addition to being suitable for weaving plain and textured fabrics, the rapier loom is characterized by easy color change and is suitable for multi-color weft fabrics. Suitable for the production of yarn-dyed fabrics, double-layer velvet fabrics, terry fabrics and decorative fabrics.pan>
Air jet loom:Use the jetted compressed airflow to pull the weft yarn and bring the weft yarn through the shed. The main features of the air-jet loom are fast speed and high labor productivity. It is suitable for plain and textured fabrics, fine and high-density fabrics and large batches. fabric.
Advantages and disadvantages of gray fabric:
(1) Jet machine produces gray cloth and general fine yarn productsThere are many varieties, and the varieties and grades are higher, mainly light and thin fabrics; rapier machines generally have more varieties of coarse yarns, and the varieties and grades are lower, mainly heavy and heavy fabrics.
(2) From the equipment point of view, air jet and rapier are just different in weft insertion.
(3) The raw material cost is the same when weaving gray fabrics of the same organization, but the weaving cost is lower. For example, for twill weaving, the jet speed can reach more than 800 rpm, and the rapier can only turn about 180-200 rpm. One person can watch the jet block. 10-12 units, and 4-6 more arrow shafts
Common characteristics and differences of fabrics
Common characteristics:All edges are rough and can be the same specifications.
Opposite gender:Under the premise that the yarn count and specifications are the same:
① The jet weight is slightly lighter.
② The flatness of air-jet flat gray cloth is better than Rapier production.
③ Air-jet loom fabric shrinkage The corresponding size will be larger
④ The quality of air-jet yarn is better than that of rapier.
