  • Patent number: 4229554
    Abstract: Flame-retardant antistatic polymer additives are provided which inhibit the buildup of electrostatic charges upon the addition of such compositions to synthetic polymeric fibers, i.e., polyamide fibers, and at the same time do not contribute to the flammability characteristics of such polymeric fibers. The flame-retardant antistatic polymer compositions are useful in combinations with fibers such as polyamide, polyester, polyurea, polyurethane, polysulfonamide, polyolefin and polyacrylic fibers. The antistatic effect is obtained by the process of coating the fibers or dispersing in or on the fibers up to about 12 percent by weight of a polymer composition which is the reaction product of:(a) a polyoxyalkylene compound or polyester thereof and(b) at least one reactant selected from the group consisting of (1) a diol, (2) a polyester and (3) an aliphatic or aromatic diacid or derivative of (3), wherein at least one said reactant is halogenated.

  • Patent number: 4217390
    Abstract: Lubricants and processing aids for synthetic fibers, particularly polyester and nylon fibers, are disclosed comprising compounds having the structural formulas: ##STR1## and ##STR2## in which R is an aliphatic group generally having about 3 to about 22 carbon atoms; A is a mixture of residues from ethylene oxide and at least one other lower alkylene oxide, preferably a heteric mixture of oxyethylene and oxypropylene residues in the respective ratio by weight of 20:80 to 90:10; and n has a value to produce a molecular weight of about 300 to about 3000.Where liquid products are desired which contain the higher numbered carbon chain residues, low viscosity compounds can be obtained by oxyalkylating a glycerol-1,3-dialkylether with a mixture of ethylene oxide and 1,2-propylene oxide in the respective ratio as set forth above.

  • Patent number: 4217394
    Abstract: There are disclosed mold-release compositions suitable for lubricating metal molds which are used in molding natural and synthetic rubber and other polymers. The mold release agents of the invention are oxidation-stable homopolymer and copolymer, i.e., block or heteric polyoxyalkylene lubricant compounds. The lubricants of the invention can be used alone or in mixtures with prior art polyoxyalkylene lubricant compounds. The polyoxyalkylene mold release lubricants of the invention have the formula: ##STR1## R is individually selected from alkyl groups of 1 to about 21 carbon atoms, preferably about 7 to about 21 carbon atoms, and most preferably about 12 to about 18 carbon atoms. In lubricants I and III, R.sub.1 and R.sub.2 are the residue of the same or different and in lubricant II different alkylene units, all individually selected from the group consisting of the residue of ethylene oxide, propylene oxide, butylene oxide and an aromatic glycidyl ether, R.sub.3 is the residue of a difunctional phenol, R.

  • Patent number: 4199647
    Abstract: Lubricants and processing aids for thermoplastic synthetic fibers, particularly polyester and nylon fibers are disclosed together with processes therefor. Said lubricants comprise compounds having the structural formula: ##STR1## in which R and R.sub.1 are independently selected from straight or branched chain aliphatic radicals having about 7 to about 22 carbon atoms; A is oxyethylene or a heteric mixture of oxyethylene and oxypropylene residues derived from the reaction of ethylene oxide and 1,2-propylene oxide in the respective ratio by weight of about 3:7 to about 9:1; and n has a value to produce a compound having a molecular weight of about 300 to about 3000. Said compounds are the ethoxylated or alkoxylated reaction product of the reaction product of an alpha-olefin epoxide and a fatty alcohol.

  • Patent number: 4165405
    Abstract: Lubricants, or processing aids, for synthetic fibers, particularly polyester and nylon fibers and most particularly for polyester fibers, are disclosed comprising a capped heteric polyoxyalkylene monoester having the formula: ##STR1## in which R is an aliphatic group having about 7 to about 22 carbon atoms; A is a mixture of oxyethylene and oxypropylene residues derived from the reaction of ethylene oxide and 1,2-propylene oxide in the respective ratio by weight of 3:7 to 4:1; n has a value to produce a molecular weight of about 300 to about 3000 and R' is derived from a monofunctional compound containing an OH group, preferably a monofunctional aryl alcohol or a monofunctional alkyl or arylalkyl alcohol, all having 1 to about 21 carbons in the alkyl chain.Certain embodiments of the invention are particularly suited by their low viscosity for application to synthetic textile fibers or yarn without dilution in water.

  • Patent number: 4145469
    Abstract: There are disclosed processes for preparing a textile treated with a water-insoluble polyester wherein a linear or branched chain water-soluble sulfonate or phosphate group containing polyester is coated or impregnated onto a textile substrate in combination with a crosslinking agent and subsequent to heating to co-react the crosslinking agent with the polyester, the treated textile substrate is exposed to an aqueous solution of a polyvalent metal ion reactive with said sulfonate or phosphate groups in said polyester.Alternatively, there are disclosed processes for preparing a water-insoluble polyester on a textile substrate wherein a branched chain polyester having sulfonate or phosphate groups is coated or impregnated onto a textile substrate, the substrate is dried and subsequently exposed to an aqueous solution of a polyvalent metal ion reactive with said sulfonate or phosphate groups in said polyester.
