摘要:
A bi-regional fiber with a cellulosic core and a wax outer sheath is disclosed. The sheath can comprise high melting temperature wax. The fiber may be produced by processing the natural fiber at temperatures less than 70°C. The fiber can be processed in a standard manner such as, for example, a Keir process which may include bleach at approximately 100°C with a wax subsequently added at a temperature sufficient to disperse the wax over the fiber surface. The fibers are ignition resistant as measured by industry standard tests. The wax may comprise from about 0.4 to 25 percent or greater of the fiber by weight. The wax may be natural wax, synthetic or emulsified wax or blends thereof. The bi-regional fibers can be blended with other fibers including BRCF fibers to create fire resistant fabrics including clothing, blankets and household materials.

Oxidized polypropylene meshes are described that help promote tissue in growth wherein the oxidized surface attracts macrophages and helps reduce inflammation about the area to which it is implanted.
摘要:
A process for removing dye and improving hand in cellulosic textiles utilizing a mercerizing ozone bath. The process also prevents redeposit of dye which is residual in a dyeing process. The time and temperature of the process is dependent upon the type of dye and the temperature the process is run. The process can be used in vat dyeing, jet dyeing, package dyeing and the like to obtain different shades of color while improving the hand and luster of the textile.
摘要:
Substrates are coated with a curable composition that includes at least one free radical polymerizable monomer and a heat-activated polymerization initiator. The coating is applied to the substrate and cured thereon to produce the coating. Curing is performed by purging molecular air from the vessel containing the substrate, pressuring with an oxygen-deficient gas and then curing the fabric in the oxygen-deficient gas at elevated pressure.

The present application relates to a method of treating a fabric article so that it has a characteristic smell normally associated with garments that have been exposed to natural sunlight, the method comprising positioning a fabric article (1) to be treated in an enclosure (8) and irradiating said fabric article positioned in said enclosure with ultraviolet light with a wavelength of between 280nm and 400nm and so that it is subjected to a predetermined radiant exposure. A device for treating a fabric article to replicate the characteristic effect of exposing said fabric article to natural sunlight is also disclosed.

A novel method for giving wool an antifelting finish is disclosed by means of which the wool is given an anionic character and the wool subsequently treated with a cationic polymer.
摘要:
A method of modifying a polymer material whereby the polymer material is modified to give a highly durable surface without decreasing its strength. Namely, a polymer material is modified by the method comprising a combination of an impregnation step, an activation step, a step of grafting a monomer and a step of a treatment with a hydrophilic polymer. Thus, the hydrophilic nature, adhesiveness, etc. of polymer materials such as polyolefins can be improved without causing any decrease in the practical strength. The thus obtained polymer materials are usable in articles with a need for high water absorptivity and high adhesiveness, for example, water−absorbing materials and water−retaining materials for medical, sanitary, cosmetic and agricultural uses, for improving adhesiveness of synthetic papers, filters, fiber products for clothes and composite materials and the like. Among all, these materials are particularly usable in orthodontical instruments, writing implements and battery separators.
摘要:
An apparatus and process for disinfecting, and, optionally, sterilizing, fibers and non-woven materials produced from the fibers is disclosed, as well as processes for converting fibers into disinfected and/or sterilized non-woven materials. The process involves contacting the fibers and/or non-woven materials with high temperature steam, and then with UV light, which is preferably UV-C light, or another disinfectant process, such as ozone treatment. The process can also involve process steps such as blending fibers, applying fibers to an air card, subjecting the fibers to one or more carding steps, subjecting the carded fibers to non-woven process steps, and chemically treating the fibers and/or non-woven materials. The resulting non-woven materials can be used, for example, in personal care, baby care (including baby wipes), cosmetic applications, household cleaning, automotive, industrial cleaning applications, industrial uses, and the like.
