Abstract:
Abrasion resistant glass fibres, and glass fibre textiles produced from rovings containing the fibres, are produced by (a) coating the fibres with a substance which converts their normal hydrophilic character to a hydrophobic character; and (b) impregnating the roving with a binder containing fine particles of a solid organic polymeric lubricant, the fine particles being held in place between the fibres of the roving by the binder, which bonds to the modified surface of the fibres. Textile composed of glass fibres normally have a poor resistance to abrasion, and this has limited their use, in spite of other advantageous properties possessed by these textiles. The present methods gives glass fibre textiles with a much improved resistance to tearing, without harming the other advantageous properties.
Abstract:
Glass fibers in the form of yarns and fabrics are provided with a surface treatment to improve their resistance to abrasion and flammability by coating the yarns and fabrics with a thickened dispersion of very fine particles of a solid organic polymeric material, drying and sintering this coating through various heating zones, and optionally padding the treated yarns and fabric with a lubricant to ensure flexibility thereof.
Abstract:
Methods for imparting decorative weave effects and designs to fibrous glass fabrics in post-weaving operations particularly comprising the transformation of stresses existing in a given weave design to yield a uniform weave pattern are provided.
