Method for manufacturing fibrous yarn
Disclosed is a method for the manufacture of fibrous yarn including the steps, where an aqueous suspension including fibers and at least one rheology modifier is provided, followed by directing the suspension through at least one nozzle, to form at least one yarn, and then dewatering the yarn.
Woven Flame-Resistant Garment Fabric, and Garment Made Therefrom
A woven flame-resistant fabric for garments, the warp and fill yarns being made up of at least about 30 wt. % inherently flame-resistant fibers. The fabric is woven from a plurality of warp yarn groups consecutively arranged across the width direction in a recurring pattern, each warp yarn group consisting of a plurality of adjacent consecutively arranged warp yarns. At least one warp yarn in each warp yarn group is woven with the fill yarns in a plain (1/1) weave and at least one warp yarn in each warp yarn group is woven in one or more non-plain weaves each selected from the group consisting of 1/2, 2/1, 2/2, 1/3, and 3/1. Approximately half of the warp yarns in the fabric are woven in a plain (1/1) weave and the remaining warp yarns in the fabric are woven in the one or more non-plain weaves, in an alternating fashion.
Blended fiber yarns and fabrics including oxidized polymeric fibers
An article comprising a fabric comprising: (a) a blended yarn comprising: (i) from about 10% to about 85% by weight of at least one biregional fiber comprising an oxidized polymer selected from the group consisting of acrylonitrile based homopolymers, acrylonitrile based copolymers, acrylonitrile based terpolymers, and combinations thereof; (ii) at least one companion fiber selected from the group consisting of FR polyester, FR nylon, FR rayon, FR treated cellulose, m-aramid, p-aramid, modacrylic, novoloid, melamine, wool, nylon, regenerated cellulose, polyvinyl chloride, antistatic fiber, poly(p-phenylene benzobisoxazole) (PBO), polybenzimidazole (PBI), polysulphonamide (PSA), and combinations thereof; and (b) optionally including a companion yarn different from said blended yarn; wherein said companion yarn includes p-aramid in an amount less than 20% of the fabric weight; and
wherein the fabric has a weight from about 3 oz/yd.sup.2 to about 12 oz/yd.sup.2.
HIGH-EFFICIENCY FLAME-RETARDANT, LIGHT, THIN AND SOFT MULTI-FIBER BLENDED FABRIC AND PREPARATION METHOD THEREOF
The present invention discloses a highly effective flame-retardant lightweight and soft multi-fiber blended fabric and a preparation method thereof. The fabric comprises 82 to 87 wt % of base fabric, 5 to 8 wt % of flame retardant and 8 to 10 wt % of antistatic agent. The base fabric comprises 45 to 48 wt % of polyacrylonitrile fibers, 40 to 42 wt % of cellulose fibers, 6 to 9 wt % of polyacrylate fibers and 6 to 8 wt % of polyamide fibers in parts by mass. The material has the characteristics of highly effective flame retardance, lightweightness and softness, with the gram weight being 215 g/m. A test shows that the material can come up to the NFPA2112 standard, and the arc-proof ATPV is greater than 8 cal/cm.sup.2.
Stabilization of slit absorbent fabric edges
Disclosed are the cut edges of an absorbent fabric comprising at least 45% and less than about 90% cellulosic or natural fibers, and a fusible component being stabilized by fusing the fusible component with an arrangement of spaced lines or spaced areas extending from the cut edges, and optionally over the entire absorbent fabric.
Functional regenerated viscose fiber
A functional regenerated cellulose fiber includes a graphene structure and non-carbon non-oxygen elements. The non-carbon non-oxygen elements includes elements of Fe, Si, and Al. The elements of Fe, Si, and Al account for 0.018 wt % to 0.8 wt % of the regenerated cellulose fiber.
ABSORBENT YARN
A yarn, absorbent components and dressings comprising the yarn, and methods of treatment for wounds using said absorbent components and dressings are disclosed. The elastomeric yarn as disclosed herein comprises a yarn core fibre and a secondary fibre disposed exteriorly around the yarn core fibre. The yarn core fibre comprises an elastomeric material, and the secondary fibre is disposed exteriorly around the yarn core fibre. The secondary fibre comprises a superabsorbent material and/or a gelling material.
Oxidized cellulose-based material, method for obtaining same and use thereof as compress
The present invention relates to a method of obtaining a solid material based on a polymer having its cellobiose units exhibiting the following characteristics: at least some of the cellobiose units have at least one carboxylic acid function attached to the C.sub.6 carbon, the other C.sub.6 carbons having a primary alcohol function attached thereto; and at least some of the cellobiose units have at least one of the two rings open between the C.sub.2 and C.sub.3 carbons, the other C.sub.2 and C.sub.3 carbons forming a ring and having an alcohol function attached thereto. Such a material, advantageously a textile, may be used as a compress.
Method of preparing a composite sheet
A composite sheet comprising two or more layers is described where the degree of abrasiveness of can be controlled. The sheet can comprise partially or wholly biodegradable or compostable materials or blends thereof. Methods of preparing the composite sheets are also described.
FLAME RESISTANT FABRIC COMPRISING A PTW FIBER BLEND
A yarn is disclosed, which includes a blend of: 33-75 wt. % of a flame resistant fiber having a limit of oxygen index of 43%, a thermal conductivity of 0.0063 watt/meter/K and a moisture regain of 12%; 10-40 wt. % of an aramid fiber; and up to 36% of a wearability enhancing fiber selected from the group consisting of wool, flame resistant rayon and lyocell, wherein the yarn is free of thermoplastics and is sufficiently flame resistant such that a fabric consisting of the yarn is effective to limit a body burn percentage resulting from 4 seconds of flame exposure to less than 35% as measured by ASTM F1930. Fabrics and garments including the inventive yarn are also disclosed.
