摘要:
A method to improve the bleach resistance of a textile fiber is provided by having the steps of:(a) applying a solution or dispersion of a compound of the formula: ##STR1## where R.sup.1 and R.sup.2 are independently selected from the group consisting of H, CO.sub.2 R.sub.4, SO.sub.3 H, PO.sub.3 H, CON(R.sup.4).sub.2, OH, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, and halo, where R.sup.4 is H or C.sub.1 -C.sub.4 alkyl;R.sup.3 is selected from the group consisting of H, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkenyl, C.sub.1 -C.sub.4 alkylenephenyl, phenyl and COR.sup.5, where R.sup.5 is C.sub.1 -C.sub.4 alkyl, phenyl or benzyl, any of which may be substituted with up to two groups from R.sub.2 ; and salts of such compounds; in a solvent selected from the group consisting of water and C.sub.1 -C.sub.4 alcohol; and(b) drying said textile fiber to evaporate said solvent and deposit a non-volatile coating of said phenolic compound on a surface of said fiber.
摘要:
Compositions and methods for treating textile substrates to obtain superior liquid repellent properties are disclosed. Durable microscopic surface structures imparted to the fibrous substrate allow liquids to bead up and roll off of its surface. Mechanical abrasion or sanding techniques may be used to create the microscopic surface structures on the surface of a fibrous textile substrate, without substantially breaking fibers, followed by a chemical treatment using, for example, fluorocarbon-containing repellent compositions. Particles may be employed in combination with repellent compositions to achieve superior repellent properties. A property of the roughened surface fibers, the Roughness Factor, is used to characterize the microscopic surface structures on the treated textile surface. Treated textile substrates are disclosed which achieve superior water and oil repellency, even after multiple abrasion or laundering cycles.
摘要:
A method of manufacturing a polyester textile fabric having a relatively low level of particulate contaminates and high absorbency is provided by heatsetting the fabric at a temperature of 300° F. or less.
摘要:
The process for producing patterns on ground dye colored textile fiber pile substrates, particularly wherein the pile fibers are in the form of yarns comprised predominantly of polyamide fiber, and wherein at least some of the ground dye component is at least partially color dischargeable and selected from vat, reactive, direct, acid, premetallized or mordant dyes, the process comprising contacting selected portions of the colored pile fibers with a reducing system which optionally can contain one or more reduction resistant dye or pigment materials for in situ coloring of the substrates, the contacting being characterized by jet forcing the reducing system interstitially of the pile fibers to deposit the reducing system thereon substantially below the surface thereof, and to effect the color discharge of at least a portion of the ground dye component.
摘要:
Provided is a flame resistant fabric comprising a fabric substrate comprising cellulosic fibers and thermoplastic fibers, and a finish applied to the fabric substrate comprising a tetrahydroxymethyl phosphonium salt or a condensate thereof, a cross-linking agent, a brominated compound, and optionally a melamine resin. Also provided are methods of preparing the flame resistant fabric.

摘要:
A liquid jet printing apparatus is provided having a nozzle for emitting a stream of liquid droplets toward a substrate, a charging section for providing an electrical charge to liquid droplets and a pair of electrically conductive deflecting plates for deflecting the liquid droplets to a desired location on the substrate, wherein the inside face of the deflecting plates is provided with dielectric layer to minimize problems associated with liquid droplets collecting and coalescing on the deflecting plates.
