the national loom when often encountered loose weft density fabric to shift in the production of glass fiber products; Roving shear is not completely; Thin cloth fabric wrinkling, end breakage rate is high; Heavy knot weft and handover failure; Refund solution and warp tension in the process of conveying poor uniformity of a series of problems, the serious influence on the quality and production efficiency. The present situation of the deep processing of glass fiber industry is: give priority to with small rapier and shuttle loom processing and low-end products, with a small amount of expensive imported equipment processing high-end products.
According to Zhou Xiangqin from Zhejiang university of technology, They cowork with Wanli textile machinery co. as a team for tackling key problems and by opening space connecting rod drive system of innovative design, a breakthrough five items:1)Based on loose weft density fiberglass fabric delivery, closed to cloth, heavy glass fiber yarn shear, back rest, heavy glass fiber weft planning design of the control system innovation, overcome the cloth roll forming process skid brings the problems such as weft to shift between layers; 2)It is to overcome the traditional scissors cut roving, weft slip shear is not completely caused by outside; 3)It is to overcome the traditional loom spring activity back rest can not timely and effective link back to the double entry opening warp tension caused by a sharp change, cause the thin glass fiber cloth fabric wrinkling, end breakage rate is high; 4)It is to overcome the heavy glass fiber yarn knot in the process of weft insertion and handover failure problem; 5)It is through to the roving fiberglass no tension of the solution inside the machine and the system and the yarn and weaving machine floor machines together by system innovation design, solve the traditional loom together through the process of glass fiber fluff, inconvenient operation and so on, reasonable use a space.
"with cooperative enterprise Wanli's glass fiber weaving equipment production experience and market advantage, our project team in detail analyzes the characteristics of different kinds of glass fiber fabric, according to the different characteristics of various kinds of fabric width, speed and weft beating-up system, open system, let-off system, coiling system, weft tension control system was designed and successfully designed for glass fiber yarn weaving machines well by the system, the system has simple structure, convenient use, reliable, and can reduce the contact link in glass fiber and mechanical parts, as much as possible to prevent the glass fiber fluff, etc. These tests if only in the school laboratory could not be achieved, I think cooperate with the enterprises and is one of the best way to speed up scientific research breakthrough." Zhou Xiangqin said.It is understood by the project team to develop high-end glass fiber weaving system key technology and equipment has been used by more than the national enterprises, project 4 invention patents, 4 utility model patents. Production of high-end glass fiber fabric, with its good insulation, heat resistance, good corrosion resistance, high mechanical strength, as the reinforcing material in compound material, electric insulation and heat insulation material, have already used the national economy in various fields, such as substrate.
