Abstract: A novel polyacetal resin blend provides for dimensionally stable rib-reinforced tubular bodies upon injection molding of the blend. The blend comprises a major proportion of an oxymethylene copolymer having a melt index of 27.0 grams/10 minutes and a minor proportion of an oxymethylene copolymer having a melt index of 9.0 grams/10 minutes to provide hydrolytic stability to the molded article. Each of the oxymethylene copolymers are formed from recurring oxymethylene units interspersed with alkylene oxide units in which the alkylene group contains at least two adjacent carbon atoms. The blend is particularly useful in forming cigarette lighter bodies.

Abstract: Solvent resistant halogenated aromatic polyester fibers are prepared by first heat treating the fibers at substantially constant length at a temperature of from about 270.degree. to about 295.degree. C. for a period of from about 5 to about 60 minutes, and then further treating the fibers with perchloroethylene which is at a temperature of from about 80.degree. C. up to its boiling point for a period of at least about 15 minutes to produce halogenated aromatic polyester fibers having improved solvent resistance.

Abstract: A process for preparing coated glass containers is disclosed. This process comprises applying a coating of an unhydrogenated thermoplastic elastomer on the outside of the glass container and then baking the coated glass container in the presence of oxygen gas at a temperature of from about 150.degree. to about 170.degree. C. for a time period of from about 10 to about 45 minutes. The coated glass containers are both glass fragment retentive and returnable.

Abstract: A powder composition having good melt flow under zero shear conditions is disclosed. A process for preparing this powder composition is also disclosed. The composition comprises a thermoplastic elastomer such as a block copolymer of styrene and hydrogenated butadiene as well as a melt flow modifier. The melt flow modifier is preferably a partially hydrogenated styrene/alpha methylstyrene random copolymer. The composition may additionally contain adhesion promoters and stabilizers against oxidation and ultraviolet light. A process for coating substrates such as a glass bottle with this composition, as well as the coated glass bottle, is also disclosed.

Abstract: A coated bottle comprising a bottle having an inner and an outer coating is disclosed. The inner coating applied to the external surface thereof is prepared from non-tacky composite powder particles which are made up of powder particles which have surface deposited thereon comparatively smaller solid particles which are hard and non-tacky. The tacky powder particles comprise a mixture of a thermoplatic elastomer, a specifically defined melt flow modifier, and an adhesion promoter. The smaller, hard particles comprise a specifically defined melt flow modifier which has a glass transition temperature of at least about 20.degree. C. The first coating is applied to the bottle, preferably by electrostatic spraying techniques, and the bottle with the particles is baked to form a smooth coating. An outer coating comprising certain particularly defined synthetic resins, particularly acrylic polymers, is then applied and the coated bottle is again baked until a smooth second coat is formed.

Abstract: A blend of discrete polyester and cotton fibers comprising a substantial proportion of polyester fibers (i.e., about 50 to 70 percent by weight polyester fibers based upon the total weight of polyester and cotton fibers) effectively is rendered non-burning while retaining the desirable textile properties (e.g., hand and aesthetic appeal) normally associated with this blend. The polyester and cotton fibers are physically admixed with discrete additive fibers formed from a synthetic aromatic polymer containing chlorine, bromine, or mixtures thereof chemically bound to an aromatic ring which is substantially free of an oxide of antimony (as described), and an organophosphorus flame retardant is topically applied to the resulting blend in a minor concentration (i.e., about 2 to 20 percent by weight based upon the total weight of the fibers of polyester, cotton, and synthetic aromatic polymer).

Abstract: The water absorbency of normally hydrophobic polyester fibers is improved by contacting (e.g., by immersing) these fibers in an aqueous solution of a hydroxyamine selected from the group consisting of monohydroxyamines, dihydroxyamines, and trihydroxyamines, and mixtures thereof.

Abstract: An assemblage of fibers is provided which exhibits highly satisfactory flame retardant characteristics in spite of the fact that discrete fibers are included within the admixture which would normally burn when exposed to flame. Included in intimate physical admixture with the fibers which would normally undergo combustion are discrete additive fibers consisting primarily of a chlorinated and/or brominated aromatic polymer having the inherent ability to render the admixture as a whole non-burning when subjected to the flame. Particularly preferred additive fibers are formed primarily of an aromatic polyester formed from the reaction of tetrabromobisphenol A, isophthalic acid, and terephthalic acid or the esterforming derivatives thereof. Also, in a particularly preferred embodiment a minor concentration of an oxide of antimony (e.g. antimony trioxide or antimony pentoxide) is intimately dispersed throughout the additive fibers.

Abstract: A dry cleaning process is provided which is effective for preventing wet-soil redeposition and improving stain-release characteristics of polyester textile material. The process advantages are accomplished by a dry cleaning solvent system contaning hydroxypropyl methyl cellulose as an anti-soiling agent.

Abstract: Heretofore, halogenated aromatic polyesters (as defined), such as those formed by the reaction of tetrabromobisphenol A, and a mixture of isophthaloyl chloride and terephthaloyl chloride, have proven to be extremely difficult to dye and to undergo a deleterious fiber degradation when dyeing is attempted in the presence of common dye carriers. Difficulties heretofore encountered when attempts have been made to dye such fibrous materials effectively are eliminated in the substantial absence of fiber degradation when practicing the present process. The dyeing of the specifically defined halogenated aromatic polyester fibrous material with an aqueous disperse dye system is carried out in a closed dyeing zone at a temperature of about 110.degree. to 130.degree.C. in the presence of a dimethylterephthalate dye carrier.
