An elastic thread yarn comprising linen and/or ramié and/or hemp and an elastic thread, with a thread made of an elastomeric material, and a substantially inextensible yarn made of linen and/or ramié and/or hemp helically wound about the elastomeric core at a predetermined number of windings per length unit of elasticized yarn, wherein, for each metric count Nm, the number of windings substantially inextensible yarn of the elasticized yarn, is set between two values indicated by two curves ( 12, 13 ) which can be expressed according to exponential laws, for example, with the same exponent, i.e. according to equations of the form T=KN 0, 327 where K is 20 and 50, respectively. In particular, an intermediate curve 11 is such that, by choosing for a given metric count a number of windings proximate to curve 11 , this best feature balance is obtained. In an exemplary embodiment, the core comprises a bare elastic thread, i.e. an elastic thread that is not coated by other fibres. In another exemplary embodiment, the core comprises an elastic thread coated with a natural fibre as cotton or viscose, or with a combination thereof. The elastic thread yarn according to the invention provides elasticized fabrics containing linen and/or on ramié, which has, in particular, a better surface regularity than well-known elasticized fabrics comprising linen, and which is comparable with the regularity of the elasticized fabrics comprising natural fibres such as cotton, wool, etc. and synthetic fibres, and also allows using ramie and hemp yarns to make elastic thread yarns and fabrics, for example, for making cloth items.

The antibacterial viscose rayon, according to the invention, is used for the manufacture of any type of textile articles, including items intended for medical use, ensuring a more lasting antibacterial and antifungal protection due to the uniform distribution of the antibacterial additive throughout the entire volume of the fibre. According to the invention, immediately before spinning, the viscose is mixed and homogenized with an antibacterial additive, and then spun following the classical procedure: the viscose solution, with required and strictly specified parameters is fed under pressure to the spinnerets of the spinning machine from which the cellulose solution enters a spin bath, where as a result of the chemical reactions in course is transformed into fibres subjected afterwards to a subsequent treatment. According to the invention, in the production of dope dyed antibacterial rayon, into the preliminarily prepared suspension composed of one or a couple of pigments, a specified amount of antibacterial additive is introduced, the obtained mix is homogenized and filtered, and then subjected to the classical stages of spinning and subsequent treatments.

Composite Low-twist Yarn Towel and Production Method Thereof

Номер: US20220064827A1
Автор: Hongxing Wang
Принадлежит: Loftex USA LLC

A composite low-twist towel that is formed of three parts: terry yarn, ground warp yarn and weft yarn. The ground warp yarn and the weft yarn are normal towel yarns and the terry yarn is a composite low-twist yarn. The composite low-twist yarn is composed of two yarns of different thickness, among them, the spun yarn is synthetic fiber spun yarn or filament yarn, and the thick yarn is the pure cotton yarn or the blended yarn of pure cotton and other fibers. The composite low-twist yarn is made into a warp beam through warping and sizing. Then, it interweaves with ground warp yarns and weft yarns through a towel loom or warp loom to form terry fabrics.

A method of manufacturing a cellulose-based shaped article. The method comprises subjecting a solution of lignocellulosic material, dissolved in a distillable ionic liquid, to a spinning method, wherein the ionic liquid is a diazabicyclononene (DBN)-based ionic liquid. DBN-based ionic liquids have good dissolution power, high thermal and chemical stability, lack runaway reactions and exhibit low energy consumption, due to low spinning temperatures.

Method of Rendering A Lacrosse Head Pocket Hydrophobic and Oleophobic

Номер: US20150059154A1
Автор: Hurley Ryan, Miceli James
Принадлежит: Epoch Lacrosse LLC

A hydrophobic and oleophobic coating is applied to the mesh netting of a lacrosse stick head in two layers. The application is made to the netting by coating the strings either before or after they are woven into the netting, but prior to installation on the lacrosse stick head. In the preferred method, each coating layer is applied in a wet thickness of 3.0 to 5.0 mils (0.003-0.005 inches). When the coating is dry, the result is a dry film thickness of 1.0-1.5 mils (0.001 to 0.0015 inches) for each layer. Thus, two layers of the coating have a total dry thickness of 2-3 mils (0.002-0.003 inches). As a result of the coating method, a surface tension is created on the surfaces of the mesh that prevents water, dirt, mud and oil from attaching to the mesh, thus preventing these materials from permeating the mesh. 1. The method of rendering a mesh pocket of a lacrosse stick head hydrophobic and oleophobic , comprising the steps of:a) providing a length of fiber made of a material chosen from the group consisting of synthetic and non-synthetic;b) weaving said length of fiber into a mesh material;c) forming said mesh material into a configuration suitable for installing over an opening in a lacrosse stick head;d) installing said mesh material over said opening to form a flexible pocket;e) said length of fiber being coated with a liquid substance which when subsequently dry imparts to an outer surface of said fiber hydrophobic and oleophobic properties.2.

Disclosed is a shoe including a sole and an upper, wherein the upper includes an inner upper and an outer upper, wherein the inner upper includes 90% or more of a wool fiber and the outer upper includes a combination of 50 to 80% by weight of the wool fiber and 20 to 50% by weight of a synthetic fiber, based on the total weight of the outer upper. The shoe according to the present invention can facilitate discharge of sweat generated during exercise through the upper made of natural wool fiber and thus offer fresh wear sensation and can be worn without socks. In addition, elasticity of wool fabric can reduce resistance of shoes depending on shape change of feet during exercise or in a daily life, thus impairing foot comfort. As a result, people whose feet swell readily, such as pregnant women, can wear the shoes without irritation. Furthermore, the shoes according to the present invention are suitable for diabetic patients whose feet need to be protected from injury because they are made of wool which is a soft elastic fiber.
