How To Reduce The Low Cost Of Weaving

Water jet looms and air-jet looms are two generations of products, and their grades and prices are not comparable. Each water jet loom needs to discharge about 4 tons of polluted water every day. In the increasingly stringent environmental protection, it is doomed to be "off class" one after another.

Of the more than 2500 textile enterprises in the "Textile City" of Shengze, as of the end of 2016, there were more than 100 thousand water looms. It is reported that in 2017, Shengze eliminated tens of thousands of stations. "Last year, the textile market was very good, and the loom brought out by the loom was very large, which made people feel bad." A textile business owner told reporters.

However, a textile enterprise's technological innovation made the local textile enterprises see the hope. Jinjda textile machinery company can turn water jet looms into air-jet looms and no longer emit a drop of sewage.

Hou Jingkui, chairman of Shengze Textile Machinery Association and chairman of Jstar textile machinery company, said, "the idea of spraying water to jet" has been more than three years old. With the increasing pressure of environmental protection, I feel that I can do something.

Water spray and air jet are all functions of replacing "shuttle" to send the weft. If we can turn the nozzle into a jet nozzle and a water pump into a gas bag, can we? Three years ago, he told his colleagues about this idea. Everyone thought he was crazy: "toads want to eat swan meat, water jet looms seventy thousand or eighty thousand yuan, air-jet looms sell for about 200000 yuan. Do you know how many years the Japanese spent jet?"

Fortunately, Hou Jingkui has some "iron rod", and director Lu Zhengang is one of them. Two years ago, Lu Zhengang resolutely accepted the task of R & D. He said that the principle seems very simple, but how to achieve it is difficult.

Lu Zhengang, who was usually not very good at speaking, talked about "water to gas": the technical requirements of the jet loom nozzle are very high, and the arrangement of a main spray and 40 pairs of jet nozzles, the direction of the gas and the flow of the gas can not be completely error. Air bag clearance is also the key. We put the gas bag in the crossbeam position. At the beginning, the flow rate of the gas is not well controlled, and it is checked and adjusted day and night. When the gas path is changed, the air pressure should be adjusted. The structure of the steel buckle of the water jet loom and the air-jet loom is different. The water spraying requires 5 millimeters away from the steel buckle, but the 5 mm jet will crack the wire and destroy it.

Hou Jingkui praised this love: "for some time, I can't keep up. I encourage him. The Japanese machine is good, but we Chinese are also the cleverest. We can definitely do it. Now," water to gas "has been successful. I am really excited. For a long time, I saw him sitting on the floor alone, painting, measuring, calculating, and getting out of it. It's not easy.

Only one loom was roaring in the huge half workshop. "This is our first" water to gas "loom, which has been working for more than 20 days, rotating at 700 rpm, and weaving for 15 hours at 1 hours. The cloth is smooth on surface, uniform in yarn and stable in quality. It is no worse than imported air-jet looms. Hou Jingkui confidently said.

On the other side of the workshop, the reporters saw that a large number of looms with light green light had been built.

The news of the success of loom's "water to gas" is open, causing a shock wave in the textile circle. Hou Jingkui's cell phone was almost blown off. In September last year, there were 116 orders. Shen Fugen, general manager of the local Fuda textile company, carefully contrasted and imported cloth woven from the jet plane. He thought the two had no difference and bought more than 40 units at once. A textile company from Fujian bought more than 60 units.

With the success of "water to gas", Hou Jingkui decided that enterprises should stop making jet looms and turn them into air-jet looms. This adjustment allowed customers who originally planned to change machines to "change to buy", because the cost of changing an old machine was more than 30 thousand, and the cost of buying a new machine was 76 thousand yuan. "The price is only 1/3 for imported jets." Lu Zhengang said.

More practical, this machine "emergency", can bring immediate economic and environmental effects - "replacement of 10 thousand units, at least for enterprises to save 1 billion yuan, less than 40 thousand tons of sewage daily discharge." Shen Fugen said.

In 2006, an enterprise in Wujiang was famous for its research and development of air-jet looms, but it eventually collapsed because of its difficulty in technology. Does Kingsta's "water to gas" success mean a new way of "bend over"? Fan Jianlong, member of the Standing Committee of the Wujiang District Committee and Secretary of the Shengze town Party committee, said the loom "water to gas" is a rich connotation of innovation, and the prospect is immeasurable. It will provide valuable transformation paths for Shengze and surrounding areas, and even a wider range of textile industry to solve environmental bottlenecks and reduce efficiency.
