The fiberglass cloth factory's production process uses the most advanced production equipment and employs professional personnel to monitor the equipment's operation and the quality of the products in order to ensure product quality and production stability.

 

Preparation

Warping

Warp and weft yarn are used to make fiberglass fabric. The purpose of warping is to arrange a specific number of weft yarns in accordance with the cloth's width and weaving requirements. To prepare sizing yarn, the warp yarns are taken up on the warp beam. The original yarn and the cloth type are used to determine the warping speed and tension. Because the tension is difficult to control, warping should be done several times.

 

Sizing

The goal of sizing is to improve lubrication and prevent hairiness or yarn breakage caused by the warp and machine friction during weaving. After the woven fabric has been woven into a cloth, it must be resized for further production. Controlling the tension during sizing is especially important to avoid it breaking and affecting the fabric quality. To remove excess water from the warp yarns, the sizing warp yarns are extruded by machine and then dried with hot steam.

 

Manufacturing Process of Fiberglass Fabric


Warp Beaming

The parallel shaft joins the warp yarns of several warp beams onto a weaving shaft to form a pan head with the desired number of warp yarns.

 

Healding

The final step in the preparation is healding. Each warp must pass through the lining machine, the heald, and the steel buckle before weaving the shaft so that it can be moved up and down on the loom to finish the weaving.

 

Weaving

Weft yarns are constantly woven with warp yarns on jet looms to create glass fabrics of various widths, basis weights, and warp and weft densities. The weaving speed increases as the looms rotational speed increases, but the friction with the warp yarn increases, making hairiness more likely. The woven glass cloth is not post-treated at this time and is a woven fabric.

 

Final Treatment

Continuous heat treatment is also known as first-time desizing. When the weaving is finished, the thickeners are no longer needed and must be removed before the cloth surface treatment. Fiberglass fabric is desized in two steps using a high-temperature desizing process. During the first desizing, 90% of the sizing will be burned.

 

Batch Heat Treatment

The second time desizing is also known as batch heat treatment. The fabric is bundled in batches after continuous desizing and then put in the second desizing furnace for desizing, almost entirely removing the residual on the surface.

  

Surface Treatment

To increase the interface strength between the fiberglass cloth and the resin, the surface of the fiberglass cloth must be treated with a silane coupling agent after desizing. To make a finished cloth, immerse the cloth surface in the silane treatment liquid and then dry it in a drying oven.
