Air jet weaving machine
is a kind of shuttleless loom which is to apply the jet air drawing the weft through the shed. The operating principle is to take advantage of air to treat it as the medium of weft insertion, and the compressed air is used to draw the frictional traction force of the weft yarn. And then the weft is carried through the jet port to achieve the purpose of weft insertion through the jet produced by the jet.
This weft insertion method is to make the weaving machine to realize the high speed and high productivity. During these several kinds of shuttleless looms, air jet weaving machine has the maximum speed of motor vehicle. Because the weft insertion method is rather reasonable, so the rate of weft insertion is relatively high, and the running operation is easy and safe, which has become the one of the fabric looms which have the most promising future. Because the air jet loom is use the flow weft inserting method, its biggest weakness is the rather high energy consumption .
Development by nations
In 1914, Americans invented the air jet weaving machine and in 1950, Czechoslovakia produced the first commercial air jet weaving machine; and then 1970s,air jet weaving machine was put into manufacturing. The air jet weaving machine in early days could only produce narrow fabric, when the weaving loom had low speed、poor quality of fabric and could only produce the plain fabric with single color 、simplicity and common design. The new type air jet weaving machine is growing largely in the aspects of the speed、automatic control level、the quality of product and the adaptability of variety, becoming the fastest growing type among the shuttleless looms. Nowadays, the foreign advanced air jet weaving machine applies a number of advanced technology, especially in the premise that electron、microelectronic technology making air jet weaving machine ensure the quality of product, whose performance increases greatly. Today, the international famous manufactures are including Tsuda Ko TOYOTA, Japan, Belgium (PICANOL), Italy Yida (Itema) and the German Dornier (DORNIER) chiefly.
The development by China
Since Shanghai Weaving Research Institute introduced ZA200 air jet loom from Japanese Tsudakoma , which is used for weaving in 1982, 1984 introduced ZA200 air jet manufacturing technology from Japanese Tsudakoma for the first time. Nowadays, the major representative national air jet weaving machine are Qingdao red flag textile JA11A, spr700 silk loom air-jet loom, Xianyang Champlain GAX type and ZA209i type, GA718 type, zhongfangji Weifang Jinshuai JS21N, Suzhou textile ASGA701 type, etc.
Nowadays, Island red flag textile machinery JA11A series, Japan Textile Group's RFJA series air-jet looms, Titan's TT- series, and Feng Kai's F series are occupying the market share, and in the international , they form a certain competitiveness.
