Abstract:
A paintable cloth includes a woven fabric including plant fibers, especially flax, jute, ramie and/or sisal fibers, the woven fabric additionally being coated with a finish.
Abstract:
The present invention is directed to a method of increasing the brightness of non-wood fibers and nonwoven fabric fabrics produced by the method. In one aspect, the method includes forming a mixture of non-wood fibers and exposing the mixture to a brightening agent to produce brightened fibers. The brightening agent is oxygen gas, peracetic acid, a peroxide compound, or a combination thereof. The brightened fibers have a brightness greater than the fibers of the mixture before exposure as measured by MacBeth UV-C standard.
Abstract:
The present invention relates to a process for manufacturing a ramie fabric and the fabric. The process comprising the following steps: blend spinning a high-count ramie fiber such as a ramie fiber of 2500Nm 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 printing and dyeing finishing process to obtain a super-high-count ramie fabric with a ramie yarn fineness of 160Nm or higher.
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:
This invention is directed to methods for the treatment of cellulose-containing fibers and yarn to provide protection to the cellulose from attack by enzymes. The method comprises the steps of exposing cellulose-containing fibers and yarn to an aqueous solution of an enzyme-repelling chemical to give the fibers or yarn a protective coating, and using the protectively coated fibers and yarn to prepare cloth or fabric. In another embodiment, the method of the invention comprises the step of exposing a fabric comprising cellulose-containing yarn to an aqueous solution of an enzyme-repelling chemical to give the fabric a protective coating. The invention also encompasses cellulose-containing fibers and yarn, including cotton, having a protective enzyme-repelling coating. The invention is further directed to denim fabric comprising cotton fill yarn having a protective enzyme-repelling coating. Such denim fabric, and any garments made therefrom, will exhibit greater strength and durability following the stonewashing procedure as compared to denim made from uncoated yarn.
Abstract:
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.

Abstract:
The present invention relates generally to substrates that exhibit useful, auto adaptable surface energy properties that depend on the environment of the substrate. Such surface energy properties provide relatively high advancing and receding contact angles for liquids when in contact with the target substrate surface. The substrates exhibit low surface energy quantities of at most about 20 millijoules per square meter (mJ/m2) at a temperature of about 25 degrees C. and a surface energy greater than about 20 mJ/m2 at, or with exposure to, a temperature of about 40 degrees C. More specifically, encompassed within the present invention are textile substrates having this highly desirable unique surface energy modification property and which exhibit wash durable oil and water repellency and stain release features. Novel compositions and formulations that impart such surface energy modifications to substrates are also encompassed within this invention, as well as methods for producing such treated substrates.
