  • Patent number: 9878185
    Abstract: Protective garments include a flame resistant fabric that is strong and yet has a soft hand. The fabric is made from a combination of filament yarns and spun yarns. The filament yarns and spun yarns are woven together such that the filament yarns are separated by from about 2 to about 5 spun yarns in both the warp direction and the fill direction. The spun yarns may contain polybenzimidazole fibers in combination with other fibers, such as aramid fibers. The filament yarns may comprise para-aramid fibers. In one embodiment, the filament yarns may have a size larger than the spun yarns.

  • Patent number: 8911508
    Abstract: The present invention discloses a modifier for modifying a polyester fiber as well as a preparation method and application of the same. The modifier contains ethylene glycol, two-hydroxy-end polyether, dimethyl terephthalate, two-polyether-end modified organosilicon and a metal acetate catalyst. A two-step continuous production process is adopted. The first step is esterification; that is, ethylene glycol, two-hydroxy-end polyether, dimethyl terephthalate, and two-polyether-end organosilicon are added into a reactor, and have an esterification reaction in the presence of the catalyst. In the second step, the materials produced by the esterification are transported to a polymerizer, and have a polymerization reaction under the conditions of high temperature, vacuum and catalyst, producing the high molecular weight polyester/polyether/organosilicon terpolymer with a molecular weight of 1000˜50000 as the desired modifier.

  • Patent number: 6863697
    Abstract: In a preferred embodiment, the present process involves subjecting a fabric having splittable conjugate yarns both to an acidic treatment and to a basic treatment, each of which erodes a portion of the components of the conjugate yarns. The acid treatment, given certain reaction kinetics, removes a portion of the polyamide element of the conjugate filament. The basic treatment has a similar effect on the polyester element of the conjugate filament, making it more hydrophilic. The at least partial removal of the polyamide component, coupled with the increased hydrophilicity of the polyester component, results in a fabric having enhanced absorptive properties. In an alternate embodiment, treatments with only acid or only basic solution may be employed.

  • Patent number: 6743261
    Abstract: The present invention discloses a functionalized fiber material treated with a emulsion containing an ascorbic acid derivative which is hardly soluble in water, wherein the ascorbic acid derivative which is hardly soluble in water is preferably tetraalkylester of L-ascorbic acid. Said treatment method comprises treating a fiber material with an emulsion comprising a mixture of an ascorbic acid derivative which is hardly soluble in water, an anionic surfactant or a combination of an anionic surfactant and a nonionic surfactant, and water, wherein a concentration of the ascorbic acid derivative which is hardly soluble in water is 0.05 to 10 % by weight. The functionalized fiber material of the present invention enables a sustained discharge of the active ingredient without losing the moisture absorption and release properties possessed by the fiber.

  • Patent number: 6736858
    Abstract: The present invention provides fiber and fiber products for topsheet of diapers and sanitary napkins having superior surface properties attained by a fiber-treating agent. The surface properties attained by the fiber-treating agent include decreased wet-back of excreted liquid through topsheet, which has been attained by modifying the structure of disposable diapers or sanitary napkins, improved durable hydrophilicity of topsheet and minimized time-dependent reduction of the durable hydrophilicity of topsheet.

  • Patent number: 6719810
    Abstract: The invention provides a method for reacting a variety of protective entities to form covalent bonds with nylon, which entities can be applied directly in the dyebath with the dyes that are used to dye the nylon without blocking such dyes or interfering with their color yield. Such protective entities include stain-blockers, chlorine resist agents, fire retardants, UV absorbers, antimicrobial agents, fume fade protectors, soil-resist agents and anti-stats. According to this method, a protective entity is reacted with a moiety having the capability of forming a covalent bond with a nylon fiber to create a modified protective entity that is adapted to form a covalent bond with a nylon fiber. The modified protective entity is added to a dyebath containing one or more dyes selected from the group consisting of fiber reactive dyes, acid dyes, acid-premetalized dyes and disperse dyes. The dyebath is applied to nylon fiber at a pH within the range of about 0.5 to about 6.

  • Patent number: 6695889
    Abstract: In textile products (e.g. yarns, woven fabrics, knit fabrics) comprising highly crosslinked polyacrylic fibers (made of acrylic fibers by partially hydrolyzing a nitrile group to generate an amido group and a carboxylic acid group), fibers blended with the highly crosslinked polyacrylic fibers can be dyed in an even hue. A pre-dyeing treatment process for such textile products (e.g. yarns, woven fabrics, knit fabrics) comprising highly crosslinked polyacrylic fibers comprises a pretreatment step of immersing the textile product into an acidic solution and treating it at a high temperature and an elevated pressure. A dyeing process comprises the steps of conducting this pre-dyeing treatment process, and thereafter conventionally dyeing fibers blended with the highly crosslinked polyacrylic fibers. A pretreated and undyed textile product and a dyed textile product are obtained by the pre-dyeing treatment process and the dyeing process mentioned above, respectively.
