And shellproof UD cloth is formed by the compound processing with gluing agent behind the fibre exhibition yarn, and the fibre is because preparation process and transportation process, remains in some impurity and static, in order to improve the state that the fibre expandes, can adopt the manual work to go to rub the gap position with the hands on the exhibition yarn roller in order to improve the exhibition yarn effect, and is inefficient, and dangerous, and exhibition yarn is average inadequately, and the raw materials has impurity to the effect is unsatisfactory when the cloth that leads to producing is used for the production of later stage product.
