Abstract: A process for the preparation of a synthetic tanning agent is disclosed whereby multi functional polymer is polymerized with sulfonated aromatic compound, pretreated with organic ligand to form an organo-polymeric matrix, which is essentially formaldehyde-free. The product has potential application in leather industry as an eco-friendly approach to chrome tanning by eliminating the conventional pickling process and the related problem of total dissolved solids (TDS) associated with the effluent. The present invention also provides for an exhaust aid for chrome due to its multiple carboxyl groups.

Abstract: A textile-care composition that advantageously combines colour preservation with care of fibres and especially greying-inhibiting action was to be developed. That was achieved by means of a composition for textile care, comprising at least one cellulase and at least one colour-fixing polymer containing imidazolidine units.

Abstract: A drycleaning method is disclosed. In the method, a composition that comprises dipropylene glycol n-propyl ether (DPnP) and is essentially free of siloxanes or polysulfonic acids is used. The composition contains at least about 80 wt. % DPnP and up to about 15 wt. % of water. The method enables superior stain removal while avoiding excessive fabric shrinkage or soil redeposition.

Abstract: This invention relates to antimicrobial polyester-containing articles and methodology for the preparation of antimicrobial polyester-containing articles utilizing chitosan and chitosan-metal complexes as the antimicrobial agent.

Abstract: The present invention is directed to a process for separating polyester, and particularly polyethylene terephthalate, from various contaminants and impurities. In general, the process includes the steps of mixing materials containing polyester with an alkaline composition in a mixer. The mixer imparts sufficient energy to the slurry to provide substantially complete, even coating of the polyester containing materials with the alkaline composition and cause saponification of the outer surface of the polyester with the alkaline composition. After reaction in the mixer, the mixture is heated causing some of the impurities to be chemically modified into a more separable form. After heating, the mixture can be washed with water and the polyester can be easily separated from the remaining impurities. Through the process of the present invention, polyester can be separated and recovered from waste materials such as those containing polyvinyl chloride and aluminum.

Abstract: The present invention provides an improved pickling and bating free process suitable for both hides and skins for making chrome tanned leathers by using a mixture of conventional chrome tanning salt and alkali metal salt is used at a pH in the range of 5–5.5.

Abstract: A process and formulation for pre-treating a cellulosic, or cellulosic blend with synthetic fiber, substrate, achieving sufficient clearness and appropriate absorbency prior to dyeing the substrate. The process having the steps of: providing a vessel; providing a cellulosic, or their blends with synthetic fiber, substrate; providing a water bath; adding an active amount of an activating compound selected from the group of: salts of organic acids, organic amine derivatives, transitional metals salts and complexes, pigments, and combinations thereof; adding an active amount of caustic soda; adding an active amount of hydrogen peroxide; achieving a pH from about 6.0 to about 9.0 at the end of the bleaching cycle; heating the water bath to a temperature in excess of 50 degrees centigrade for a pre-determined period of time; and dropping the bath.

Abstract: The flame retardant treating agent of the invention comprises a phosphorus-based compound represented by the following formula (4), for example. According to the invention, a polyester fiber woven fabric is immersed in a treatment solution containing the flame retardant treating agent and is heat treated at a prescribed temperature in order to fix the flame retardant treating agent to the polyester fiber woven fabric to obtain flame retardant treated fiber. As a result, it is possible to maintain adequate fiber cleaning durability and achieve a sufficient flame retardant property even by post-treatment, without using halogen-based compounds.

Abstract: Warp size lubricants are disclosed. Processes of making and using the warp size lubricants are also disclosed. Methods of reclaiming one or more components of a warp sizing composition are also disclosed.

Abstract: The present invention relates to methods of imparting color and ultraviolet protection to synthetic yarns or substrates. More specifically, the present invention is directed to a method of solution dyeing a polymeric material during polymerization to form a base color shade, and subsequently dyeing the polymeric material by either yarn dyeing or piece dyeing. Ultraviolet protection is also provided in the solution dyeing step, by introducing an ultraviolet stabilizing agent into the polymer. The base shade may then be transformed into a useful color pallet with enhanced lightfastness properties by applying a final color shade late in the fabric formation process.

Abstract: The present invention relates to methods to achieve improved cleaning of both wet washable and dry cleanable fabrics. The present invention is carried out by exposing the fabrics to an aqueous vapor and a lipophilic fluid, optionally, but preferably followed by an extraction of both.

Abstract: Flame retardant treating agents according to the invention comprise a phosphorus-based compound represented by the following formula (4): Flame retardant treated fibers can be obtained by immersion of polyester fiber woven fabrics and the like in a treatment solution containing the flame retardant treating agents and accomplishing heat treatment at a prescribed temperature. It is thereby possible to impart adequate flame retardance to polymer materials such as fibers and thermoplastic polymers even when used in small amounts, and provide flame retardant treating agents that contain no halogen compounds.

Abstract: The present invention provides an animal fibers having improved shrink proofing and pilling resistance properties and method for preparation thereof. An animal fiber having excellent shrink proofing and pilling resistance and retaining its original water repellency is also provided. A method of treating animal fiber in which a surface layer part of animal fiber is primary-oxidized in advance with an oxidizer, and aqueous treatment liquid containing ozone in the form of ultrafine bubbles of 5? or less is allowed to collide against the fiber by blowing the liquid on the fiber in the aqueous treatment solution, and then, the fiber is treated with a reducing agent. Particularly, the above-mentioned method for treating animal fiber in which ultrafine bubbles of ozone are formed by using a line mixer. The method in which an apparatus which collects the ultrafine ozone bubbles in aqueous treatment liquid on the fiber is used so that the bubbles are not scattered out of a treatment reaction bowl.

Abstract: Durable antimicrobial treatments for textile fabrics are provided. Such treatments preferably comprise silver ions, particularly as constituents of inorganic metal salts or zeolites. This particular treatment requires the presence of a resin binder, either as a silver-ion overcoat or as a component of a dye bath mixture admixed with the silver-ion antimicrobial compound. Such a treatment is extremely durable on such substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its antimicrobial activity. The particular treatment method, as well as the treated textile fabrics are also encompassed within this invention.
