  How to sizing fiberglass roving?


    For fiberglass roving made of glass fiber, single yarn generally needs to be sizing, and filament double-strand yarn can not be sizing. Glass fiber fabrics are all in small batches. Therefore, most of them are sizing by dry sizing or slitting and sizing machine, and not many are sizing by warp sizing machine. Sizing with starch slurry, starch is used as a sizing agent, as long as a small sizing rate (3%) is used. If using a warp sizing machine, some PVA or acrylic size can be used.
