Fabric care compositions for providing improved stain repellency are described. The fabric care composition includes a mixture including a hydrophobic fluid, a particulate material and an amphoteric or cationic oligomeric/polymeric deposition aid. Methods for providing improved stain repellency for a textile by treating the textile with the fabric care composition are also described.
摘要:
An acrylic-fiber finish for use in carbon-fiber production contributes to high tenacity of resultant carbon fiber. The acrylic-fiber finish for carbon-fiber production includes an epoxy-polyether-modified silicone and a surfactant. The weight ratios of the epoxy-polyether-modified silicone and the surfactant in the total of the non-volatile components of the finish respectively range from 1 to 95 wt % and from 5 to 50 wt %. The carbon fiber production method includes a fiber production process for producing an acrylic fiber for carbon-fiber production by applying the finish to an acrylic fiber which is a basic material for the acrylic fiber for carbon-fiber production; an oxidative stabilization process for converting the acrylic fiber produced in the fiber production process into oxidized fiber in an oxidative atmosphere at 200 to 300 deg.C.; and a carbonization process for carbonizing the oxidized fiber in an inert atmosphere at 300 to 2,000 deg.C.
摘要:
Silicone coating on various soft supports, for instance textiles, made of synthetic polymers (polyamide, polyester) provides an efficient method for producing water impermeable and water permeable coatings, on soft supports, said method enabling to improve permeability to water vapor of the silicones while preserving impermeability to water. The inventive method enabling this consists mainly in: coating one of the surfaces of the support with a film formed by an invert water-in-oil silicone emulsion comprising a continuous oily silicone phase phi s, crosslinkable into elastomer and including a polyorganosiloxane (POS) A crosslinkable by addition polymerization, by cationic process or free-radical process; optionally a crosslinking organosilicon compound B; and optionally at least a catalyst C; an aqueous phase phi a; a stabilizing agent; and in ensuring crosslinking of the silicone phase phi s and elimination of water. The invention also concerns water impermeable and water vapor permeable soft polyamide or polyester substrates obtained by using an invert water-in-oil silicone emulsion.

摘要:
To improve fire resistance, a fire resistant agent is included in a carbon fiber felt constituting a carbon fiber aggregate, and a binder resin for bonding the carbon fiber constituting this aggregate. The fire resistant agent comprises a phosphorus-containing compound, a boron-containing compound, a silicone compound, or the like. The proportion of the fire resistant agent is about 1 to 30 parts by weight relative to 100 parts by weight of the carbon fiber. The obtained carbon fiber felt and a heat insulating material formed by the felt are excellent in fire resistance.

摘要:
The reaction product obtained by cohydrolysis and condensation of (A) a fluorinated alkyl-bearing alkoxysilane, (B) an amino-bearing alkoxysilane, and (C) an alkoxysilyl-bearing polyorganosiloxane is dissolved in water to provide a water-soluble, water/oil repellent treating composition. This water/oil repellent treating composition has improved water solubility and shelf stability, has no detrimental effects on the environment because of the aqueous system, and imparts fully durable water repellency and satisfactory softness and hand to textiles.
