Abstract:
An elastic thread yarn comprising linen and/or ramie 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 ramie 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 = K N 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 ramie, 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.
Abstract:
The present invention relates to a process for manufacturing a ramie fabric and the fabric. The process comprising the following step: blend spinning a high-count ramie fiber such as a ramie fiber of 2500 Nm or higher with a water-soluble fiber as carrier to form a yarn; sizing the yarn at a low temperature; weaving the yarn to form a gray fabric; then removing the water-soluble fiber from the gray fabric by deweighting the gray fabric during a finishing process after printing and dyeing to obtain a super-high-count ramie fabric with a ramie yarn fineness of 160 Nm or higher.
Abstract:
Dyed fabric compositions have now been discovered that often have a balanced combination of desirable properties. The dyed fabric comprises one or more elastic fibers wherein the elastic fibers comprise the reaction product of at least one ethylene olefin block polymer and at least one crosslinking agent. Often the fabrics are characterized by a color change of greater than or equal to about 3.0 according to AATCC evaluation after a first wash by AATCC61-2003-2A.
Abstract:
A spun yarn comprising poly(trimethylene terephthalate) staple fibers at a content of at least 15% by weight, the spun yarn having an elastic recovery percentage of elongation at 5% elongation (%) ≥ 0.1 X + 70 (wherein X represents the content of poly(trimethylene terephthalate) staple fibers in the spun yarn (wt%)). The spun yarn is excellent in knitting and weaving characteristics, stretchability and stretch-back property and in shape stability and durability when worn for a prolonged period of time.
Abstract:
The inventive method provides highly desirable hand to various different types of fabrics through the initial immobilization of individual fibers within target fabrics and subsequent treatment through abrasion, sanding, or napping of at least a portion of the target fabric. Such a procedure includes 'nicking' the immobilized fibers thereby permitting the fibers to produce a substantially balanced strength of the target fabric in the fill and warp directions while also providing the same degree of hand improvements as obtained with previous methods. Furthermore, this process also provides the unexpected improvement of non-pilling to synthetic fibers as the 'nicking' of the immobilized fibers results in the lack of unraveling of fibers and thus the near impossibility of such fibers balling together to form unwanted pills on the fabric surface. Fabrics treated by this process are also contemplated within this invention.
Abstract:
The present invention relates to a method for scouring a bast fiber, the method including: a first scouring step of immersing a bast fiber in a first scouring agent and heating the bast fiber (step 1); a step of dehydrating the first scoured bast fiber (step 2); a second scouring step of immersing the dehydrated bast fiber in a second scouring agent and heating the bast fiber (step 3); a step of dehydrating and cleaning the second scoured bast fiber (step 4); and a step of drying the cleaned bast fiber (step 5). Since the blast fiber is immersed in the scouring agent for 24 hours in an existing method for scouring blast fiber, the blast fiber is damaged. However, since the fist scouring step is performed for 50 - 55 minutes, and the second scouring step is performed during 30-35 minutes, the method for scouring the blast fiber of the present invention has the advantages in that a scouring time may be reduced and the damage of the fiber may be prevented.
