It is also provided a product obtained by the present process.
Abstract:
A mattress, foundation, or other upholstered sleep product or article includes a core and barrier material surrounding the core. The barrier material includes flame and heat-resistant material that is configured to prevent combustion of the core when the upholstered article is impinged with a gas flame according to California Technical Bulletin 603 of the State of California Department of Consumer Affairs. The barrier material may include an intumescent material that is configured to swell and char in the presence of a flame so as to form a barrier to the flame and to heat generated by the flame.
Abstract:
A liquid flame retardant composition is in the form of an admixture which includes a phosphate-based flame retardant, ammonium hydroxide and zinc borate. The invention extends to a method of providing a phosphate-based liquid flame retardant composition, to the use of a phosphate-based flame retardant, ammonium hydroxide and a zinc borate in the manufacture of a liquid flame retardant composition, to a cellulosic material treated with the liquid flame retardant composition and to a method of inhibiting strength loss in a cellulosic material when the cellulosic material is exposed to heat.

Abstract:
The invention relates to a method for removing a contaminant from a gas phase or a liquid phase by contacting an article composed of (1) a fabric or cellulosic fiber and (2) a polyoxometalate, wherein the polyoxometalate is incorporated in the fabric or cellulosic fiber, with the gas phase or liquid phase containing the contaminant. The invention further relates to a polyoxometalate-modified fabric composed of a fabric and a polyoxometalate of the present invention incorporated in the fabric. The invention further relates to an article containing the polyoxometalate-modified fabric. The invention further relates to a method for making the polyoxometalate-modified fabric, by contacting the fabric with a polyoxometalate to produce a polyoxometalate-modified fabric.
Abstract:
A textile having high fluorine adhesion rate, and excellent water- and oil-repellency can be obtained by a method of producing a treated textile, comprising steps of: (1) preparing a treatment liquid comprising a water- and oil-repellent agent which comprises at least one fluorine-containing compound selected from the group consisting of a fluorine-containing polymer or a fluorine-containing low molecular weight compound, (2) adjusting pH of the treatment liquid to at most 7, (3) applying the treatment liquid to a textile, (4) treating the textile with steam, and (5) washing the textile with water and dehydrating the textile, wherein the treatment liquid comprises a thermally gelling substance and a salt.
Abstract:
A carbon fiber felt constituted of a carbon fiber aggregate and a binder for joining the fibers of the aggregate is improved in fire resistance by incorporating a fireproofing agent into the felt. The fireproofing agent is composed of one or more members selected from among phosphorus compounds, boron compounds, silicone compounds, and so on. The fireproofing agent is used in an amount of about 1 to 30 parts by weight per 100 parts by weight of carbon fibers. The carbon fiber felts thus obtained and heat insulators made by using the same are excellent in fire resistance.
Abstract:
A method for producing a fiber membrane of nanofibers that have both smooth and porous surface features. The method includes materials processing using polymer mixes with solvents and melt polymers with additives. The method includes nanomaterial incorporation onto a fiber structure after formation of the fiber structure. The fiber structure can be a part of a nanoparticle carrier material, a nanoparticle disposal medium, a lighting medium, and a catalysis medium.
Abstract:
The present invention provides a fabric and a fabric structure made of yarns with reduced water absorption. The fabric comprises yarns and interstices between the yarns, the interstices between the yarns having an average width of greater than 100μm. At least one of the yarns is comprised of multiple fibers. Said at least one yarn has voids between the fibers wherein the voids are filled up with a polymer material. The interstices remain open and the size of the interstices is the same as before the treatment. The filling of the voids between the fibers with the polymer material prevents the absorption of water into said voids and therefore leads to reduced water absorption of the fabric. The polymer material is substantially only located within the voids of the yarn and has embedded the fibers within the outer surface of said yarn.
