Method for folding plain edges of shuttleless glass fiber cloth

Abstract

The invention discloses a method for folding the plain edges of shuttleless glass fiber cloth. A cloth supporting plate (1) is arranged at the position of a cloth fell of the conventional shuttleless glass fiber loom; the two ends of the cloth supporting plate have an acclivitous inclination angle (2) respectively, so that the cloth supporting plate has a supporting function and serves as a clothtemple; and an improved broken twill cloth weaving process is adopted for folded glass fiber yarn parts on the two sides of the glass fiber cloth. By improving the structure of the cloth supporting plate, the cloth supporting plate has the supporting function and serves as the cloth temple at the position of the cloth fell, so that the temple defect is overcome, friction among edge warp yarns is reduced, the end breakage rate of the warp yarns is reduced, the operation rate is improved, and yield and quality are improved; the improved broken twill cloth weaving process is adopted for the folded glass fiber yarn parts, so that the woven glass fiber cloth does not have rough edges, the cloth surface flatness, thickness and mellowness of the plain edges and the whole cloth are uniform and consistent, the cloth does not have edge marks and is integrated, and the process quality requirement is met; and waste edge yarn parts are not required to be twisted by a twister through a smart designof denting, and weft yarns are effectively cut on time to meet folding length and tension requirements.

Description

technical field [0001] The invention belongs to the technical field of glass fiber fabric weaving, and mainly relates to a method for folding edges of a shuttleless glass fiber smooth edge cloth. Background technique [0002] At present, glass fiber cloth woven by shuttleless looms has burrs larger than 0.5cm on both sides of the fabric width. These burrs will not only bring certain operational difficulties to users (some users even refuse to use them), but also Will cause unnecessary waste. Therefore, the burr problem restricts the widespread use of shuttleless glass fiber cloth. Whether we can learn from the smooth edge folding method in the cotton spinning process to solve the problem of the rough edge of the glass fiber cloth has always been the direction of our research, because the cotton fiber is elastic, and the temple device installed on the edge of the cloth can not only play a good supporting role, Moreover, there will be no side support defects on the selvedge....

AI Technical Summary

Problems solved by technology

[0003] It is obviously not feasible to directly apply the above smooth edge tuck-in process to the smooth edge tuck-in process of glass fiber cloth, because glass fiber has no elasticity and poor wear resistance. fluff break

In addition, the folded-in edge part is plain weave, which cannot meet the requirements of glass fiber cloth for warp force, weft force and thickness appearance, so it cannot solve the problem of glass fiber cloth burrs
