Flame resistant fabrics and garments that have improved resistance to pilling and/or abrasion are disclosed. The fabrics, the fibers or yarns that make up the fabrics, or garments made from the fabrics are treated with a finish composition that is applied to the fibers, yarns, fabrics, or garments and then cured. The finish composition increases the resistance to pilling and/or abrasion of the fibers, yarns, fabrics, or garments. The finish composition includes a polymeric abrasion resistance aid, an alkylfluoropolymer, a polyethylene, and a wetting agent.

High-voltage insulation systems are simplified and can have a thinner design by the use of an external corona shielding system that may include an electrically conductive PTFE fabric. Thermal conductivity may also be improved.

Provided are a silica glass yarn and a silica glass cloth which have a signal transmission speed that is made stable through stabilization of a characteristic impedance in addition to a low dielectric constant and a low loss. The silica glass yarn has a yarn habit density of 0.10 piece/cm or less of yarn habits each having a bending point with a radius of curvature of 5 mm or less and a bending angle of 120 or less. It is preferred that the silica glass yarn have a tensile strength of 2.0 GPa or more, and silica glass filaments forming the silica glass yarn each have a breaking start strength of 80.0% or more of the tensile strength of the silica glass yarn.

A fabric for thermal management including the cooling of an object, such as a person's skin. The fabric is formed of a plurality of functional zones arranged to extend the period of cooling without the use of artificial cooling chemicals. The functional zones include one or more of three different functional zone types. The first type diverts moisture. The second type retains and stores moisture. The third type absorbs moisture. One of the functional zones may be punched to create perforations to provide fabric flexibility and to assist in liquid diversion from within the fabric. An anchor system facilitates retention of the fabric on the object.

The invention concerns a novel silica sol material and its use for producing bioabsorbable and biodegradable silica gel materials having improved properties. The materials such as for example fibers, fibrous nonwoven webs, powders, monoliths and/or coatings are used, for example, in medical technology and/or human medicine, in particular for wound treatment.

Novel absorbable polymer blends are disclosed. The blends are useful for manufacturing medical devices having engineered degradation and breaking strength retention in vivo. The blends consist of a first absorbable polymeric component and a second absorbable polymeric component. The weight average molecular weight of the first polymeric component is higher than the weight average molecular weight of the second polymeric component. At least at least one of said components is at least partially end-capped by a carboxylic acid group. Further aspects are medical devices made therefrom.

Multi-functional and high-performing fabric comprising a first layer of yarns woven to form the fabric wherein the yarns comprise at least one unitary graphene-based continuous graphitic fiber comprising at least 90% by weight of graphene planes that are chemically bonded with one another having an inter-planar spacing d.sub.002 from 0.3354 nm to 0.4 nm as determined by X-ray diffraction and an oxygen content less than 5% by weight. A majority of the graphene planes in such a continuous graphitic fiber are parallel to one another and parallel to a fiber axis direction. The graphitic fiber contains no core-shell structure, has no helically arranged graphene domains or domain boundaries, and has a porosity level less than 5% by volume, more typically less than 2%, and most typically less than 1% (practically pore-free).
