Abstract:
A softener composition is provided which is excellent in softening effect and can impart feelings of nongreasiness and cleanness to clothes. This softener composition comprises (a) a heterocyclic compound bearing one C8-36 alkyl or alkenyl group which may be interrupted by an ether, ester or amide linkage and containing nitrogen as the heteroatom and (b) an anionic surfactant bearing a C8-36 hydrocarbon group at a specific (a)/(b) molar ratio.
Abstract:
This invention relates to complexes of ultraviolet absorbers with quaternary ammonium compounds which are substantially free from unwanted salts. Such complexes are formed through ionic bonds formed between the two compounds. The inventive complexes are then removed of substantially all excess inorganic salt so as to obtain a UV absorber compound which exhibits improved light- and washfastness properties, which easily coats subject surfaces, which provides excellent non-fogging and non-cracking characteristics, and which also possesses anti-static, anti-microbial, and anti-abrasion properties. This invention also concerns methods of making and utilizing such inventive ultraviolet absorbing complexes.
Abstract:
The present invention deals with a process for oxidation of a hydroxy group of C1 and/or C2 and/or C3 and/or C4 and/or C5 and/or C6 of a sugar monomer of an oligo- or a polysaccharide comprising contacting, in an aqueous medium, the oligo- or the polysaccharide with a phenol oxidizing enzyme and an enhancing agent, whereby an oligo- or a polysaccharide with altered characteristics compared to the native oligo- or polysaccharide is created.
Abstract:
A textile finishing composition includes a copolymer; a water-soluble crosslinking agent comprising an epoxy group; and water. The copolymer includes repeating units derived from a carboxylic acid-containing monomer; and repeating units derived from a polymerizable halamine precursor. The textile finishing composition can be useful for providing finished textiles having antibacterial, antifungal, and antiviral properties.
Abstract:
Aqueous dispersions (U) containing: (A) a UV-light-absorbing textile treatment agent and (B) a dispersant system containing (BX) a non-ionogenic, polymeric, hydrophilic dispersant or a mixture of such dispersants and (BY) a non-ionogenic or anionic, vinyl-polymeric, hydrophilic thickener or a mixture of such thickeners; and optionally at least one of the following further components: (BZ) at least one non-ionogenic or anionic surfactant other than (BX); (BW) at least one dispersing auxiliary other than (BY); (C) by-products and/or concomitants; (D) at least one formulation additive; and (E) at least one agent for setting the pH are particularly stable and are very useful for the UV-active finishing of textile material.
Abstract:
A composition and method used to impart UV radiation absorbing and IR radiation reflecting properties to textiles. The composition includes a benzotriazole derivative-type UV radiation absorbing chemical, a hindered amine light stabilizer capable of reflecting IR radiation, and an emulsifier which enables the two ingredients to form an emulsion for use with currently used textile color application processes. A method of manufacturing textiles using the above composition is also provided.
Abstract:
Discontinuous fibers are coated with binder and solid particulate materials are adhered to the fibers by the binder. The fibers are typically substantially continuously coated with the binder. The binder material may be heat bondable and the treated fibers may be mixed with other fibers for use in producting a wide variety of structures and products.
Abstract:
The invention provides a process for aminoarylating cellulosic materials such as cotton and reconstituted fibres and a process for treating the aminoarylated cellulose with an effect chemical such as a dye, flame retardant or cross linking agent. Improved take up of the effect chemical by the modified cellulose means increased efficiency in the process and in the case of dyeing, avoids or reduces the washing off of hydrolysed dye and the resultant production of large volumes of contaminated water requiring to be treated. The cellulosic material may be present in a blend with other types of fibre for example a blend with poly(alkyleneterephthalates) or polyamides.
Abstract:
Provided herein are processes for topically applying an antimicrobial finish to a textile substrate, such as a yarn, a fabric, a composite, or an assembled article (for example, a garment). Specifically, the antimicrobial finish is based on hindered amine compounds that are applied in an aqueous bath (such as a commercial or home laundry setting), using the factors of pH and compound solubility to promote the formation of a durable antimicrobial halamine finish. Advantageously, the antimicrobial finish, which may be applied to fabrics made of any of a variety of fiber types and combinations of fiber types, has been found to be durable to repeated launderings.
