Process for detwisting glass fiber and creel structure thereof

Abstract

The invention discloses a process for detwisting glass fibers and a creel structure thereof. The process comprises the following steps: putting a precursor fiber tube on a creel which can rotate along the axial direction, then passing precursor fibers through a yarn guide bar, a lower roller, an upper roller, a twizzle, a balloon ring and a steel wire hook of a twister, and finally twisting the precursor fibers on a plastic bobbin on a spindle. The lower roller provides motive power so that the precursor fibers of the glass fibers release yarns through the rotation of the creel along the tangential direction of the precursor fiber tube; and an anti-slip mechanism is sleeved between the creel and a shaft. The joint part of the creel and the precursor fiber tube finishes the positioning of the relative positions of the creel and the precursor fiber tube by an elastic tensioning mechanism.

Description

technical field [0001] The invention relates to a glass fiber unwinding process and a creel structure thereof. Background technique [0002] The passive yarn output method in the industry is the free decompression process: place the raw yarn bobbin on a fixed creel, and guide the raw silk along the axial direction of the raw silk bobbin through the yarn guide rod installed in front of the raw silk bobbin axis , Through the yarn guide of the yarn guide rod, the clamping of the upper and lower rollers applies power, and the twisting and winding are completed under the rotation of the spindle. The disadvantage of this process is that: during the process of retreating the original yarn, one or two single fibers in the outer ply yarn are broken first, and the broken yarn is still tightly wound on the surface of the silk tube, causing other fibers in the ply yarn to be affected by the delysis of the inner layer. Bondage, and eventually all decapitated. Especially for the raw sil...

Problems solved by technology

The disadvantage of this process is that: during the process of retreating the original yarn, one or two single fibers in the outer ply yarn are broken first, and the broken yarn is still tightly wound on the surface of the silk tube, causing other fibers in the ply yarn to be affected by the delysis of the inner layer. Bondage, eventually all decapitated

Especially for the raw yarn after drying, the structure of the yarn cake is relatively hard, and it is difficult to find the end again, which makes the untwisting production unable to continue, and the utilization rate decreases
