A method and system for forming composite yarns having selected performance characteristics including cut resistance and/or fire/heat resistance. The composite yarn will include a core of one or more filaments and a fiber bundle wrapped about the core and integrated with one or more additional filaments that help bind the fibers about the core. An additional filament or other composite yarn can be plied together therewith to form the finished composite yarn. The core filament(s) will be selected from cut and/or fire/heat resistant materials, while the fibers of the fiber bundle and the additional filament(s) wrapped about the core can be selected from natural or synthetic fibers or filaments having additional desired properties.

A polymer-sheathed multi-filamentary strand for use in braided covers for wiring harnesses intended for use in challenging embodiments comprises a core of glass filaments wrapped in an aramid yarn, and sheathed in a siloxane-modified polyetherimide polymer. Shielding against electromagnetic interference may also be provided.

Fireproof fabric comprising a set of warp threads (C1, . . . C6) and a set of weft threads, wherein said warp threads (C1, . . . C6) are arranged on a plurality of warp levels (A, B, C); all said warp levels are bound together by at least one weft thread (T5) acting as a binding thread and arranged so as to prevent relative slipping of said levels, and at least one of the set of weft threads and the set of warp threads is formed by elasticized threads, comprising a core of elastically deformable material lined with a fireproof material.

The present invention belongs to the technical field of gloves, and relates to a biodegradable glove and a preparation method thereof. It comprises the following steps: S1, passing a glass fiber or steel yarn metal through a yarn tension controller and the spindle hole as the yarn core, and winding and wrapping the biodegradable filament yarn as the outer yarn to form the coated yarn for gloves, then weaving into textile gloves on a glove knitting machine; S2. gum dipping the textile gloves to form the degradable gloves. The preparation method is simple and easy to operate, and is suitable for large-scale production.

The heat resistant separation fabric for use as tool cover in glass processing comprises heat resistant yarns (100). The heat resistant yarns comprise a core (110) and at least one wrap yarn (123, 125). The core is a core yarn. The core yarn is a multifilament glass yarn. The at least one wrap yarns (123, 125) comprises stainless steel fibers. The core yarn is present in the heat resistant yarn without crimp. The at least one wrap yarn is wrapped around the core yarn.

A composite yarn. The composite yarn has a glass core having a linear weight ranging between 50 to 400 deniers and composing from 15 to 60% of a total linear weight of the composite yarn. The composite yarn has a sheath surrounding the glass core, where the sheath is constituted at least of fibers of meta-aramid. The sheath constitutes a remainder of the total linear weight of the composite yarn. The composite yarn has a yarn count between 10 tex and 80 tex.
