Provided is a glass cloth with which suitable impregnation properties with low dielectric resins can be obtained.

A glass cloth includes glass yarns composed of a plurality of glass filaments, woven as warp and weft yarns, and surface-treated with a surface treatment agent, wherein when embedding the glass cloth in an epoxy resin and curing the resin, and thereafter observing a cross section of the glass cloth, a filament adhesion ratio (a number of adhesion points between filaments adhering to each other/total number of filaments) is greater than 0 and 0.80 or less.

A METHOD FOR MELT PROCESSING OF TEXTILE WASTE MATERIAL AND PRODUCTS OBTAINED BY THE METHOD

A method for melt processing of textile waste material, wherein the textile waste material includes (1) at least one thermoplastic polymer material, such as polyurethane, polyester, nylon, cellulose or elastane, and (2) at least one cellulose-containing material, such as cotton textile, cotton blends with synthetic or natural polymers, regenerated cellulose-based textiles, the method adapted to prepare a composite material, including (a) chemical pretreatment of the textile waste material; (b) thermomechanical processing of the chemically pretreated material of step (a), including melt compounding, optionally including addition of recycled PET, plasticizers, such as glycerol, PEG and vegetable oils, and/or toughening polymers, such as natural rubber and polyurethane; thereby obtaining a composite material including homogenous polymer composites and/or nanocomposites, wherein the at least one thermoplastic polymer material essentially constitutes a matrix phase and the at least one cellulose-containing material essentially constitutes a reinforcement phase of the composite material.
