Abstract:
A spun yarn includes 20 to 80% by mass of a polyester-based fiber having a flat multifoliar cross section and 20 to 80% by mass of a cellulose-based fiber. A cross-sectional shape of the polyester-based fiber having a flat multifoliar cross section is a flat shape having 6 or more convex parts on a circumference thereof. The polyester-based fiber having a flat multifoliar cross section has the specific flat ratio and specific modified shape ratio.
Abstract:
Flame resistant fabrics are formed by warp and fill yarns having different fiber contents. The fabrics are constructed, for example, by selection of a suitable weaving pattern, such that the body side of the fabric and the face side of the fabric have different properties. The fabrics described herein can be printable and dyeable on both sides of the fabric and are suitable for use in military and industrial garments. Methods of forming flame resistant fabrics, and methods for forming garments from the fabrics, are also described.
Abstract:
The present invention provides a production method for purified polysaccharide fibers in which carbon disulfide emission is suppressed while efficiently producing purified polysaccharide fibers having excellent strength, purified polysaccharide fibers produced by using the production method, a fiber-rubber complex using the purified polysaccharide fibers, and a tire having excellent tire characteristics using the fiber-rubber complex. The production method for purified polysaccharide fibers of the present invention is a production method for purified polysaccharide fibers of wet-spinning or dry-wet-spinning polysaccharide by bringing a polysaccharide solution obtained by dissolving a polysaccharide raw material in a liquid including an ionic liquid into contact with a solidification liquid including an ionic liquid, in which a concentration of the ionic liquid in the solidification liquid is 0.4% by weight to 50% by weight and the anionic moieties of the ionic liquid in the polysaccharide solution and the ionic liquid in the solidification liquid have one or more types selected from the group consisting of a phosphinate ion, a phosphate ion, and a phosphonate ion.
Abstract:
Textiles are provided that include fibrous cellulosic materials having an α-cellulose content of less than about 93%, the fibrous materials being spun, woven, knitted, or entangled. The fibrous cellulosic materials can be irradiated with a dose of ionizing radiation that is sufficient to increase the molecular weight of the cellulosic materials without causing significant depolymerization of the cellulosic materials. Methods of treating textiles that include irradiating the textiles are also provided.

Abstract:
A phosphorus-containing polymer comprises a plurality of phosphorus atoms, wherein about 75% or more of the phosphorus atoms in the phosphorus-containing polymer are present in phosphine oxide moieties. An article comprises a textile material having at least one surface and a phosphorus-containing polymer disposed on a least a portion of the surface, wherein the phosphorus-containing polymer comprises a plurality of phosphorus atoms, and wherein about 75% or more of the phosphorus atoms in the phosphorus-containing polymer are present in phosphine oxide moieties.
Abstract:
Fire resistant garments are disclosed made from a fabric containing a fiber blend. The fiber blend contains meta-aramid fibers, fire resistant cellulose fibers, non-aromatic polyamide fibers, and optionally para-aramid fibers. In one embodiment, a relatively lightweight fabric is produced that has been treated with a flame resistant polymer composition. The treated fabric is particularly well suited for producing jackets and trousers that are not only flame resistant, but also offer wind resistance and water resistance.
Abstract:
This woven/knit fabric contains composite yarn comprising a multifilament yarn A2 and a multifilament yarn B2, which satisfies the following conditions (1) to (3): (1) the ratio (WA2/DA2) of the yarn length of the multifilament fiber A2 during absorption of moisture and humidity (WA2) to the yarn length of the multifilament yarn A2 under conditions of 20° C. and 65% humidity (DA2) is 1.02 to 1.30; (2) the ratio (WA2/DB2) of the yarn length of the multifilament yarn A2 during absorption of moisture and humidity (WA2) to the yarn length of the multifilament yarn B2 under conditions of 20° C. and 65% humidity (DB2) is 0.9 to 1.1; and (3) the drying shrinkage stress (DS value) of the multifilament yarn A2 is 0.08 cN/dtex or more.
Abstract:
Fire resistant garments are disclosed made from a fabric containing a fiber blend. The fiber blend contains meta-aramid fibers, fire resistant cellulose fibers, non-aromatic polyamide fibers, and optionally para-aramid fibers. The non-aromatic polyamide fibers are present in an amount sufficient to dramatically improve the abrasion resistance of the fabric without adversely interfering with the flame resistant properties. In addition to abrasion resistance, the particular blend of fibers has also been found to dramatically improve or increase various other properties. In one embodiment, the fabric is made with a herringbone weave which has been found to unexpectedly improve tear properties and porosity.
Abstract:
Disclosed are a cellulose-based filament for a tire cord, a bundle including the same, a twisted yarn including the same, and a tire cord including the same. The cellulose-based filament is suitable for use in a tire cord has advantages in that strength deterioration due to twisting is remarkably low and elongation is improved, and thus the fatigue resistance is good.
