Abstract: A method of dyeing polypropylene fiber to create areas of different color on the fiber. A first dye solution containing a disperse dye and a dye-promoting agent is applied to substantially the entire surface of the fiber to cover the fiber with a first color. Thereafter, and while the fiber surface is still wet with the first dye solution, a second dye solution containing a disperse dye of a second color is applied only to selected discontinuous areas of the fiber. The second dye solution displaces the first dye solution in those areas of the fiber surface to which the second dye solution is applied. Then, the fiber is subjected to an elevated temperature high enough, and for a period of time sufficient, to fix the dyes in the fiber. Preferably, the second dye solution is more viscous than the first dye solution. After the dye fixation step, the fiber is scoured to remove excess dye. If desired, the second dye solution also contains a dye-promoting agent.

Abstract: A shaped polyolefin structure, such as a polyolefin fiber or a nonwoven web containing polyolefin fibers, is rendered hydrophilic by contacting the structure with a gaseous mixture of chlorine, sulfur dioxide, and oxygen or carbon monoxide or a mixture thereof, in the presence of a free radical-producing means. Such treatment results in the formation of hydrogen sulfato groups at the structure surface. Preferably, the hydrogen sulfato groups are converted to ammonium sulfato groups by subsequent treatment with ammonia or a sufficiently basic amine.

Abstract: Improved lubricant compositions useful as finishes for polypropylene fibers, filaments and yarns and comprised of components which meet the requirements of 21 CFR 178.3400 as indirect food additives are provided. The finish compositions are comprised of specific ethoxylated secondary linear alcohols, specific ethoxylated linear or branched alcohol phosphate esters neutralized with potassium or sodium hydroxide and water. A hydroxylic coupling agent may also be present.

Abstract: Ethylene or propylene polymers are dyed by dispersing a small quantity of a copolymer of a C-14 or higher alpha-olefin and maleic anhydride therein and subsequently treating the composition with an aqueous solution of a basic dye stuff such as Malachite Green.

Abstract: Compositions of nickel salts of 4-hydroxybenzoic acids and esters of aliphatic or aromatic carboxylic acids, which esters have boiling points of at least about 250.degree. C. are useful for stabilizing polyolefins against degradation by heat and ultraviolet radiation and for rendering polyolefins dyeable.

Abstract: Oxidized C.sub.20+ alpha-olefins are useful in improving the properties of textiles.

Abstract: Durable excellent water absorption property and antistatic property can be given to synthetic fiber by a simple method. In the method, a polymerization initiator is absorbed in the fiber and then the fiber is applied with a water-soluble polymerizable monomer and heat treated to form a polymer thereon.

Abstract: Textiles containing blends of a proteinous animal fiber and polypropylene are rendered shrink-resistant by heating the textile to a temperature of about 165.degree.-250.degree. C. for a period of 0.1 to 60 seconds.

Abstract: It has been found that nickel-containing polyolefins can be dyed and printed in deep colors and with very good to excellent fastness properties when a thiazole-azo-(3-cyano-2,6-dihydroxypyridine) dyestuff is used.

Abstract: A nonwoven mat of polyolefin fiber is contacted with a gaseous sulfur dioxide-chlorine mixture to sulfo-chlorinate the surface of the polyolefin fibers to a relatively high sulfur content and then preferably treated with an amine, either after compacting the mat or before compacting the mat to form a structure suitable as a battery separator. The mat can be used for other structures besides battery separators. And it can be separated into individually wettable staple fibers before compaction, i.e. individual separate fibers which are wettable.
