A process for manufacturing a bonded fabric for high performance industrial belts is provided. The process includes providing a base fabric made up of warp yarns provided with a predetermined elasticity and weft yarns provided with a lower elasticity than the warp yarns, and subjecting the base fabric to a bonding treatment.

This invention is related to a method of manufacturing a cotton weft knit fabric that is resistant to fraying, curling, and laddering. The unique fabrication method described herein generates a cotton fabric that resists edge fraying and curling when cut. As a result of the unique manufacturing method described herein, the typical garment hemming process typically used to prevent hemming and fraying in weft knit fabric is not required.

The present invention relates to make stretch yarn by using at least two roving and two elastomeric filaments with variable draft to allow the yarn made in the fabric to get good stretch, good recovery and good shrinkage. The invention is applicable for all types of fibers material and is not limited in the yarn count. The said invention yarn is woven into fabrics exhibiting the excellent stretch characteristics and functional performance for commercial application.

Thermoformed molded articles are made containing and from fabrics containing spandex and cellulose ester fibers. In the process for making the molded article, a fabric is layed up in a mold a thermoformed at a temperature not exceeding 195° C., and for a residence time sufficient to obtain a molded article that retains its shape upon release from the mold, said fabric comprising cellulose ester fibers. The three-dimensional molded articles can now be made containing sustainably derived fibers, e.g. cellulose ester fibers, that have good shape retention, comfort, and hand. Examples of such molded articles include support garments, such a brassiers.

An elastic woven fabric comprising weft and warp yarns, the weft yarns including elastic composite yarns each of which comprises an elastic core yarn and a sheath yarn covering the elastic core yarn, and the warp yarns including chemical fiber yarns and/or natural fiber yarns. Each of the elastic composite yarns is in a form of a singly-covered yarn in which the elastic core yarn is covered by a single layer of the sheath yarn helicoidally wound around a periphery of the elastic core yarn, a number of turns of the sheath yarn per 1 meter of the elastic core yarn being in a range of 1,000 to 2,500 T/m. A stretching magnification ratio of each of the elastic composite yarns, in the elastic woven fabric in a weaving process, is retained equal to or less than 1.30 folds based on the elastic composite yarn before weaving.

A method is disclosed for making an elastic core yarn (50), wherein an elastic core (30) comprising a fibre (10) of natural rubber with metric count 200-1000 dtex is covered by a cotton-based covering yarn (40), comprises a step of conveying the elastic core (30) and the covering yarn (40) in such a way that the covering yarn (40) laterally attains a proximity of the elastic core (30) in a wrapping space (35); a step of helically wrapping the covering yarn (40) about the elastic core (30) in a wrapping space (35), wherein the conveying speed, and therefore the winding/unwinding speed, is selected such that the elastic core (30) is stretched up to a stretching ratio of at least 2, and such that, during this wrapping step, the covering yarn (40) becomes twisted with a final twist direction opposite to its initial twist direction, and forms a number T of coils per length unit of the elastic fibre (10) set between a predetermined minimum value T.sub.0 and a predetermined maximum value T.sub.1 both depending on the linear mass density Nm of covering yarn (40), the wrapping space (35) being enclosed by a container (67). An elasticised yarn obtained this way, and a fabric, in particular a denim type fabric, manufactured from this yarn.

The present disclosure provides a knitting apparatus, including: a frame; a primary yarn guide mounted on the frame; a primary yarn control rod connected to the primary yarn guide; a secondary yarn guide mounted on the frame; a secondary yarn control rod connected to the secondary yarn guide; a needle plate provided at lower ends of the primary yarn guide and the secondary yarn guide; a control cam separately drives the primary yarn control rod to control the primary yarn guide to move, and drives the secondary yarn control rod to control the secondary yarn guide to move; a tension spring connected to the control cam; and an electromagnet. A magnetic force of the electromagnet drives the tension spring to extend and retract, and further drives the control cam to rotate up and down.

The present invention is directed to a reactive dye-dyeable polyurethane-urea elastic yarn including a reaction product of at least two polyols, a diisocyanate compound, a diamine chain extender, an amine chain terminator, and a diethylenetriamine compound, wherein one of the polyols is polyethylene glycol, which is included in an amount of 20 to 30.0 mol % based on the total amount of the polyols, a polyurethane-urea polymer includes 10 meq/kg to 45 meq/kg of primary amine ends, and the capping ratio (CR) of the diisocyanate to the polyols is 1.8 to 2.0.

The present invention relates to a fiber structure including an elastic polyurethane yarn. The elastic polyurethane yarn contains: 0.5 to 10 mass % of a cationic high-molecular-weight compound A having a number-average molecular weight of 2000 or more; and an inorganic chlorine deterioration inhibitor B. The mass ratio of the cationic high-molecular-weight compound A to the inorganic chlorine deterioration inhibitor B ranges from 0.3 to 3, and a silicone oil is applied to the elastic polyurethane yarn. The fiber structure is treated with water repellent finishing. The fiber structure preferably includes an elastic polyurethane yarn whose ratio of fluorine (F) to carbon (C) on the elastic polyurethane yarn is 0.030 or more in an elemental mass concentration according to scanning electron microscope-energy dispersive X-ray spectroscopy (SEM-EDX). Thereby, it is possible to provide a fiber structure having high water repellency and keeping a low water retention rate when immersed in water for an extended time.

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.
