摘要:
The fabric finishing agent is a solution of a graft copolymer composed of an organopolysiloxane moiety and a grafting moiety thereon obtained by the graft copolymerization of an acrylic or methacrylic monomer, optionally, in combination with monomers of other types. The fabric finishing agent is capable of imparting various kinds of fabric materials with greatly improved soft but non-sticky feeling of touch with resilient elasticity and the effect of treatment is durable and resistant against laundering and dry cleaning.
摘要:
A novel silicone-based fabric finishing agent is proposed which is particularly suitable for finishing a fabric material containing keratinous fibers, e.g., wool, for imparting the fabric material with excellent shrink-proofness and soft and pleasant feeling of touch even after repeated laundering treatments. The fabric finishing agent is an aqueous emulsion of a hydroxy-containing organopolysiloxane with admixture of a mixture of colloidal silica and a reaction product of an amino-functional alkoxy silane or a hydrolysis product thereof with an acid anhydride, an epoxy-functional alkoxy silane compound and a curing catalyst.

The inventive fabric treatment agent can impart excellent hydrophilicity to fabric materials of, in particular, synthetic fibers with durability and launderability. The principal ingredient of the agent is a copolymer composed of three types of moieties including (a) a diorganopolysiloxane terminated at both molecular chain ends each with a non-silanolic hydroxy group or other active hydrogen-containing group, e.g. --SH, --COOH and --NH.sub.2, (b) a polyol compound having polyoxyalkylene linkages which is typically a polyoxyethylene glycol and (c) a diisocyanate compound which serves as a coupling agent between the moieties (a) and (b).

The silicone-based fiber finishing agent is particularly suitable for synthetic fiber-made fabric materials such as waddings of polyester fibers to impart excellent softness and smoothness in touch and free from yellowing even by heating with high resistance against dry cleaning. The fiber finishing agent comprises (A) an organopolysiloxane of a substantially linear molecular structure terminated at each molecular chain end with a silanolic hydroxy group or alkoxy group and having at least one amino-substituted hydrocarbon group bonded to the silicon atom in a molecule, (B) an epoxy-containing alkoxy silane compound such as methyl dimethoxy 3-glycidyloxypropyl silane and (C) an epoxy-containing organic compound free from silicon such as glycidyl alcohol and glycidyl methacrylate.
摘要:
The organopolysiloxane in the inventive latex is modified with phosphonate ester-containing groups such as those expressed by the formula --Si--CH.sub.2 CH.sub.2 --PO(OEt).sub.2 (Et: ethyl group) and --Si--CH.sub.2 CH.sub.2 CH.sub.2 --PO(ODd).sub.2 (Dd: dodecyl group) and exhibits excellent performance in the applications as a fabric treatment agent and the like. The inventive organopolysiloxane latex can be prepared by the polymerizing reaction of an organosilicon compound or, preferably, an organopolysiloxane and a phosphonate ester-modified alkoxysilane emulsified together in an aqueous medium containing a surface active agent of the class of the organic sulfonic acid type or a sulfate ester type ones which serves both as an emulsifier and as an acid catalyst.
摘要:
An excellently pleasant feeling of softness and elastic resilience can be imparted to a fabric material treated with the inventive fabric finishing agent which is an aqueous emulsion of a copolymer obtained by the emulsion polymerization, in an aqueous emulsion of an organopolysiloxane having radical-polymerizable groups, e.g., vinyl groups, or mercapto-substituted hydrocarbon groups, e.g., 3-mercaptopropyl groups, as the polymerization medium of an acrylic or methacrylic monomer, e.g., alkyl acrylates and methacrylates, in a specified amount relative to the amount of the organopolysiloxane. The acrylic or methacrylic monomer may be partly replaced with a polyfunctional monomer, e.g., acrylic and methacrylic acids, N-methylol acrylamide, glycidyl methacrylate, 2-hydroxyethyl methacrylate and the like, and/or a monomer of the third class, e.g., styrene and acrylonitrile. The emulsion may be further admixed with an organohydrogen polysiloxane as a crosslinking agent and a catalyst for the crosslinking reaction.
