Embodiment 1-5
[0022] Embodiment 1-5 relates to a kind of flat glass fiber fabric, and it is prepared according to the following steps:
[0023] 1. Wire drawing: use narrow and long bushings with an aspect ratio greater than 3 to draw to make flat precursors. The specifications of the precursors in each embodiment are shown in Table 1;
[0024] 2. Raw silk warping and hedging reed process: the yarn bobbin seat is a raw silk bobbin seat with a diameter of 200mm±5, and the raw silk is drawn out from the bobbin to form a yarn sheet. The tension is divided into 4 areas and controlled by an electromagnetic tensioner. Set on the panel and warp with low tension; the warp thread passes through the warp dropper, heald and reed in sequence according to the process requirements, and the warp yarn passes through the warp threading method sequentially, and the number in the threading method represents the warp threading method. On which pages of heald frames, the warping tension and reeding process of ea...

Abstract
The invention relates to the field of flat glass fiber fabrics, in particular to a manufacturing method of a flat glass fiber fabric and the flat glass fiber fabric. The manufacturing method of the flat glass fiber fabric comprises the steps that protofilaments which are coated with an impregnating compound and are not doubled and twisted are directly used as warp yarns and weft yarns to be subjected to warping, weft insertion and weaving, wherein the protofilaments are flat protofilaments, the width of the protofilaments is 0.5-1.5 mm, the diameter of the protofilaments is 3.5-7 micrometers, and the linear density of the protofilaments is 3.5-22 tex. The specification of the protofilaments is limited to obtain the protofilaments with good knittability, and the protofilaments can be directly woven, so that the step of unwinding, doubling and twisting the protofilaments is omitted, the weaving process is reduced, the production efficiency is improved, and meanwhile, the situation that the protofilaments are abraded in the unwinding, doubling and twisting process is avoided, and the production quality of the fabric is improved.
Description
technical field [0001] The invention relates to the field of glass fiber fabrics, in particular to a method for manufacturing a flat glass fiber fabric and the flat glass fiber fabric. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance. It has various types and has the characteristics of good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. Glass fiber fabric is formed by interweaving glass fiber as warp and weft threads. Fabrics are widely used due to the performance characteristics of glass fibers. [0003] The traditional method of preparing glass fiber is usually to decompose and twist the glass fiber precursor to form a twisted yarn to improve the weavability of the glass fiber, and then carry out sizing, paralleling, weaving, inspection, and feeding. Library, and finally get the fiberglass fabric. In the process of unwinding and merging, the glass fiber strands will rub...
