Glass Fiber Fabric Production: From Warping to Weaving – A Professional Guide

The following figure shows the flow of Glass Fiber Fabric manufacturing.

Usually glass fiber cloth manufacturing is divided into the following steps

1.Warping

Purpose of warping is line up the warp yarn on warping beam according to width and weight of fabric, hence may ready for sizing process.

2.Sizing

Purpose of sizing is avoiding the damage of warp yarn by friction of weaving parts to yarn breakage or damage on surface. It also may combine several warp beams into one weaving beam to reach enough yarn ends.

3.Heddling

Before weaving beam loading on weaving loom, all warp yarn need to be hooked up with heddles, droppers & reed.

4.Weaving

We use high speed air-jet weaving looms for weft yarn insertion.

5.De-Sizing 1

After weaving, the sizer need to be removed from fabric, fiber glass fabric is using high temperature treatment which will remove most of seizer out.

6.De-sizing 2

After the 1st desizing, the embryonic is set in a batch oven to to continued heated to remove the rest 10% sizer off.

7.Finishing

After desizing, the fabric should be treated by the SILANE to improve the interlocking ability between the glass fabric and epoxy resin.

8.Fabric examination for quality checking

Check the fabric quality and cut off the un-qualified parts when necessary.
