specific Embodiment approach 1

[0012] The technical solution adopted in this specific embodiment is: its production process is as follows:

[0013] 1. Preparation of blended fiber yarn: Add a PP yarn winding and unwinding device on the special furnace table of the alkali-free glass fiber pool kiln wire drawing production line. In the process of drawing glass fiber roving, press glass fiber: PP fiber = 6: 4 Up and down fluctuation ±10%) proportionally design the yarn number, wind the PP yarn and the E-glass thermoplastic roving together to form, and then dry and shape to obtain the desired E-glass fiber and PP yarn blended fiber yarn. The process of fiber yarn is as follows: total yarn number is 800±40tex, glass fiber: PP fiber=6:4 (up and down fluctuation ±10%), winding ratio is 7.2, package is 17±1.0kg, oil content (glass fiber ) is 0.55±0.15%;

[0014] 2. Preparation of glass fiber cloth: Put the above-mentioned blended fiber yarn on the warping creel, stick all the yarns with tape after they are arrange...

Abstract

The invention relates to the technical field of fiber cloth, in particular to fiberglass cloth special for thermoplastic fiberglass reinforced PP composites. A production process of the fiberglass cloth includes preparation of blended fiber yarn, preparation of the fiberglass cloth, and posttreatment; the step of preparation of the blended fiber yarn includes adding a PP yarn unreeling on a coil base special for an alkali-free fiberglass melting furnace drawing line, and designing yarn count according to the proportion of fiberglass: PP fiber=6:4 in the process of twistless fiberglass roving. Production cost is lowered, the production process is simplified, product strength is enhanced, and the fiberglass cloth is suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of fiber cloth, in particular to a special glass fiber cloth for thermoplastic glass fiber reinforced PP composite materials. Background technique [0002] Thermoplastic materials refer to materials that have the characteristics of softening by heating and hardening by cooling. 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 reuse. Among them, thermoplastic glass fiber reinforced PP is a widely used material. [0003] The conventional thermoplastic glass fiber reinforced PP composite material is a composite material in which the thermoplastic glass fiber is chopped into 0.2-7mm and uniformly distributed in the PP matrix. The production process is divided into two processes: granulation and molding. The granulation is to chop the thermoplastic glass fiber and heat and mix it with PP p...
