Textile Processing Aid Compositions, Or Processes Of Preparing (e.g., Lubricants Or Antistatic Agents For Fiber, Yarn, Fabric, Etc.) Patents (Class 252/8.81)
Abstract: The present invention relates to a method of reducing the clogging of nozzles and slits and diminishing the formation of deposits in the spin bath system in the process of making viscose filamentary and film materials by using an alkoxylated polyamine surfactant having the formula:
RNA&Parenopenst;CnH2nNA&Parenclosest;x−1A (I)
where R represents a hydrogen or an aliphatic group with 1-24 carbon atoms, each A represents a hydrogen, an aliphatic group with 1-24 carbon atoms, or H(OCmH2m)y-groups, where m is a number from 2-3, n is a number from 2-3, x is 4-8, with the proviso that the number of H(OCmH2m)y-groups are from 1 to x+1, and the total number of carbon atoms in the aliphatic groups is from 8 to 45. The alkoxylated polyamine surfactant has an excellent anticlogging effect, since it is a good dispersant and prevent or reduce precipitation in the spin bath. In addition it is very stable.

Abstract: The invention provides a finish composition for synthetic filament, which does not generate fume and tar at high speed and high temperature, imparts superior lubricity at high temperature, superior antistaticity and yarn winding performance, and has satisfactory biodegradability. The finish composition for synthetic fiber of the invention is characterized by containing one or more of polyether polyester compounds having a molecular weight of 1,000 to 20,000 and represented by the formula: X—(A—B)n—A′—Y. In the formula, each of X and Y is independently hydrogen, or a residue of C1-8 linear or branched saturated alcohol or C1-18 fatty acid; each of A and A′ is a residue of ethylene oxide/propylene oxide block or random copolymer containing ethylene oxide and propylene oxide from 9:1 to 1:9 mol ratio; B is an aliphatic dibasic acid residue represented as OOC(CH2)mCOO; m is an integer from 1 to 4; and n is an integer from 1 to 3.

Abstract: A process for making a tertiary amine ester of the following formula (I):
the process comprising:
(a) reacting a ketone or an aldehyde having the formula
with a glycol to form a ketal or an acetal;
(b) reacting the ketal or the acetal with acrylonitrile to form an ether nitrile;
(c) reducing the ether nitrile to a tertiary amine ketal or a tertiary amine acetal;
(d) hydrolyzing the tertiary amine ketal or the tertiary amine acetal to a tertiary amine diol; and
(e) esterifying the tertiary amine diol to the tertiary amine ester of formula (I), wherein R1 and R2 are each independently a hydrogen atom or a linear, branched, or cyclic alkyl, alkylene, alkaryl, or aryl-containing group containing 1 to 18 carbon atoms; and
each R3 are each independently of one another fatty acid radicals having 6-22 carbon atoms.

Abstract: A fiber treatment composition is disclosed. The composition contains siloxanes having amine-, polyol-, functionalities. The composition provides good hand, resistance to yellowing, and hydrophilicity to the fibers. The composition is preferably formulated as an aqueous emulsion. Applying the composition to textile fabrics produces treated fabrics having good hydrophilicity, good hand, and resistance to yellowing.
