Abstract: A method for making an elasticised yarn includes feeding a roving made of a cotton-based natural fibre at a weight percentage of at least 50% and having a linear mass density between 0.1 Nm and 50 Nm, to a stretching unit, and extracting it from the stretching unit at a speed higher than the unwinding speed. The stretched roving and an elastic fibre are jointly pulled through an overlapping unit, forming a spool of the elasticised yarn. The elastic fibre includes a natural rubber containing more than 80% polyisoprene 1,4-cis. The elastic fibre also includes sulphur as a vulcanization agent; a vulcanization accelerator and a vulcanization activator; an anti-tacking agent; an antioxidant agent; and a stabilisation agent. The elastic fibre is obtained by longitudinally cutting a longitudinally cut flat yarn made of the natural rubber, to attain a linear mass density between 50 dtex and 1000 dtex.

Abstract: A stapled melt spinning method for producing nonwoven fabrics with hygroscopic metastatic feature. Firstly, fuse bio-polyamide 6,10 into melt, extrude and spin it out spin heads of extruder into filaments, cool, draw and collect filaments into tow, then extend, cut and card the filaments into the staples, and spread the staples on a conveyer to form fibrous web. Next, blend and dissolve pulp by N-methylmorpholine N-oxide (NMMO) dissolving solvent, dehydrate it to form dope, and extrude and spin it out spin heads of extruder into filaments, then cool, draw and collect filaments into tow, and extend, cut and card filaments into staples, then overlay the staples over existing fibrous web to form a composite fibrous web of bio-polyamide 6,10 and cellulose filaments. Finally, coagulate, regenerate and convert fibrous composite of bio-polyamide 6,10 and natural cellulose into nonwoven fabric with hygroscopic metastatic feature by hydro-entangled needle punching, drying, winding-up processes.

Abstract: A fibre structure formed from dissolvable glass fibres is provided, the dissolvable glass fibres being formed from one or more boron compounds and one or more alkali compounds. The dissolvable glass can be formed into filaments, rovings and staple fibres of varying composition, length and diameter dependent on functionality and purpose. A mixture of chemicals components are heated, melted and then drawn or extruded into dissolvable filaments, rovings and staple fibres for use in a fibre-reinforced composite part or as a preservative in the internal and surface treatment of solid wood and engineered composite panels. A water-soluble surface coating may be applied to adjust dissolution rate and facilitate binding into an air-laid nonwoven mat or incorporation into other matrices.

Abstract: Textiles are provided that include fibrous cellulosic materials having an α-cellulose content of less than about 93%, the fibrous materials being spun, woven, knitted, or entangled. The fibrous cellulosic materials can be irradiated with a dose of ionizing radiation that is sufficient to increase the molecular weight of the cellulosic materials without causing significant depolymerization of the cellulosic materials. Methods of treating textiles that include irradiating the textiles are also provided.

Abstract: This document describes techniques and apparatuses for attaching electronic components to interactive textiles. In various implementations, an interactive textile that includes conductive thread woven into the interactive textile is received. The conductive thread includes a conductive wire (e.g., a copper wire) that that is twisted, braided, or wrapped with one or more flexible threads (e.g., polyester or cotton threads). A fabric stripping process is applied to the interactive textile to strip away fabric of the interactive textile and the flexible threads to expose the conductive wire in a window of the interactive textile. After exposing the conductive wires in the window of the interactive textile, an electronic component (e.g., a flexible circuit board) is attached to the exposed conductive wire of the conductive thread in the window of the interactive textile.

Abstract: The present disclosure provides mint-containing composite cellulose fibers and production methods thereof. A mint-extract crude solution is prepared from a whole mint plant after at least one water extraction process and at least one ethanol extraction process to provide a mint-extract filtrate and mint-extract residues. The mint-extract filtrate is used as the mint-extract crude solution. The mint-extract crude solution is treated to prepare a mint-extract stock solution by at least a quenching process. A viscose spinning solution is prepared by mixing the mint-extract residues with one or more pulps selected from a cotton pulp, a wood pulp, a bamboo pulp, a wool pulp, a linen pulp, a silk pulp, a Tencel pulp, and a Modal pulp. The one or more pulps contain cellulose. A mint-viscose blend is prepared by dynamically mixing the mint-extract stock solution with the viscose spinning solution and then spun into the mint-containing composite cellulose fiber.
