E-glass Fiber Reinforced Textile-sizing Research And Applied Research

Compared with the ordinary roving and the yarn, the reinforcing yarn has characters of the intensity high, the better resistance to wear, the quicker wet-out with the resin and undergoing harshly weaving condition. The glass fiber produced with the traditional roving size or the yarn size is difficulty to meet these requirements.The weaving fabrics which woven with yarn must be dealt with the hot clean to remove behind the treating compound coating to be able to use, because the glass fiber surface layer is covered with starch protective film and the resin matrix is difficult to combine with it. After the progress of the long time heat-treatment; the fabric intensity is lost seriously. And it is no problem to the copper clad laminate, but it is difficult to satisfy with the fiber glass of three spinning axises for the tremendous loss of the fabric intensity. The process of starch production is intricate, and the diffusion of the yarn size film produced by the process of the yarn is poisonous to the human health. The yarn size confection is a complex process. In the weaving process the usual yarn needs to be wrapped, to be starched, to be woven and to be desized etc., but the roving only needs to be wrapped and to be weaved. Only the process using roving can save the nearly 2,000 Yuan per ton compared with using yarn. Ordinary roving can satisfy with the resin good wet-out, but cannot undergo the harsh manufacture condition.We grip the characteristic and the application methods of each kind of size raw material through the research of the yarn size and the roving size various components and the performance of their glass fiber production. The fiber glass which to be produced utilize the modern technical method and the reasonable use to the many kinds of size raw material synthesize the roving and the yarn merit. Therefore, the kind of glass fiber is called the reinforcing yarn, and the size is called the reinforcing yarn size.Through the research of the reinforcing yarn formula, we know that the film...
