Abstract

The invention discloses a production process of special glass fiber cloth for a thermoplastic glass fiber reinforced PP composite material, and relates to the technical field of fiber cloth. A PP yarnwinding and unwinding device is additionally arranged on a special furnace platform for an alkali-free glass fiber tank furnace wiredrawing production line, during drawing of glass fiber rovings, winding and forming are carried out on PP yarns and the alkali-free glass fiber thermoplastic rovings according to the ratio of 6:4 of glass fibers to PP fibers, and then drying and shaping are carried out to obtain required alkali-free glass fiber and PP yarn blended fiber yarns; the alkali-free glass fibers and PP yarn blended fiber yarns are put on a warping creel, all the yarns are bonded by using an adhesive tape after the yarns are arranged, the yarns are wound on a warp beam with the breadth of 2220+ / -10 mm, and drafting, denting, beaming and weaving are sequentially carried out on the warp beam according to the twill weave of 2 / 2 or 1 / 3 to prepare fiber cloth; and post-processing is carried out. According to the production process, the production cost is reduced, the production process is simplified, the product strength is improved, and large-scale production is facilitated.

Description

technical field [0001] The invention relates to the technical field of fiber cloth, in particular to a production process of glass fiber cloth special for thermoplastic glass fiber reinforced PP composite materials. Background technique [0002] Thermoplastic materials refer to the characteristics of materials that soften when heated and harden when cooled. Compared with thermosetting materials, they become soft and flow when heated, and harden when cooled. This process is reversible and can be repeated, so it has the effect of repeated use. Among them, thermoplastic glass fiber reinforced PP is a widely used material. [0003] The existing thermoplastic glass fiber reinforced PP composite material is a composite material in which thermoplastic glass fibers are chopped into 0.2-7mm and evenly distributed in the PP matrix. Its production process is divided into two processes: granulation and molding. Pelletization is to heat and mix thermoplastic glass fibers with PP particl...
