Flange false twist textured nylon

Claim 2

False twist textured nylon continuous monofilament yarn having a boardability factor less than about 2.0, a twist liveliness of less than about 600 and having uniformly applied thereon about 0.5 to 2.0 percent by weight based on the weight of the yarn a finish consisting essentially of 40 to 90 percent of a lubricant selected from the class consisting of mineral oil having a viscosity of about 8 to 25 centistokes at 25* C., an ester of a carboxylic acid having a chain length of about 12 to 18 carbon atoms with an alkyl alcohol having a chain length of about three to seven carbon atoms and mixtures thereof; 5 to 35 percent of a nonionic alkoxylated emulsifier and 5 to 30 percent of a lower alkanolamide of a fatty carboxylic acid having a chain length of about eight to 18 carbon atoms as an antistatic agent.

Claim 3

The yarn of claim 1 having a boardability factor of about 1.0 to 2.0, a twist liveliness of about 450 to 600 and wherein the lubricant is mineral oil or an ester of a straight chain fatty acid with an aliphatic monohydric alcohol, the emulsifier is the condensate of ethylene oxide with an organic compound containing an active hydrogen atom and the antistatic agent is a mono- or di- lower alkanol amide of a straight chain fatty acid.

Claim 4

The yarn of claim 2 having thereon about 0.75 to 1.25 percent of the finish.

Claim 5

The yarn of claim 2 having thereon about 1.0 percent of the finish.

Claim 6

The yarn of claim 2 comprising nylon 6,6.

Claim 7

A knit structure comprising the yarn of claim 5.

Claim 8

The yarn of claim 2 comprising nylon 6.

Claim 9

A knit structure comprising the yarn of claim 7.

Claim 10

A knit article comprising the yarn of claim 2.

Claim 11

The yarn of claim 2 wherein the emulsifier is the condensate of about 2 to 12 mols of ethylene oxide per mol of fatty acid or alcohol having a chain length of about eight to 20 carbon atoms.

Claim 12

The yarn of claim 2 wherein the antistatic agent is the mono- or di- methanol and/or ethanol amide of a mixture of fatty acids derived from cocoa.

Claim 13

A process for producing a nylon monofilament yarn suitable for knit goods which comprises heating said yarn by passing said yarn at about 1,000 to 5,000 feet per minute through a 2 to 30 inch heating zone maintained at about 150* to 220* C., friction false twist texturing said yarn under conditions to impart about 20 to 40 turns per inch of false twist to said yarn, said twist running back to said heating zone, cooling the yarn for about 5 to 50 milliseconds between said heating means and said false twist insertion means, uniformly applying on yarn about 0.5 to 2.0 percent by weight based on the weight of the yarn a finish consisting essentially of 40 to 90 percent of a lubricant selected from the class consisting of mineral oil having a viscosity of about 8 to 25 centistokes at 25* C., an ester of a carboxylic acid having a chain length of about 12 to 18 carbon atoms with an alkyl alcohol having a chain length of about three to seven carbon atoms and mixtures thereof; 2 to 35 percent of a nonionic alkoxylated emulsifier and 5 to 30 percent of a lower alkanolamide of fatty carboxylic acid having a chain length of about eight to 18 carbon atoms as an antistatic agent, and then taking-up said yarn using a ring and traveller mechanism while inserting low real twist into said yarn in the opposite direction of said false twist.

Claim 14

A process for producing a nylon monofilament yarn suitable for knit goods which comprises heating said yarn by passing said yarn at about 1,000 to 5,000 feet per minute through a 2 to 30 inch heating zone maintained at about 150* to 220* C., friction false twist texturing said yarn under conditions to impart about 20 to 40 turns per inch of false twist to said yarn, said twist running back to said heating zone, cooling the yarn for about 5 to 50 milliseconds between said heating means and said false twist insertion means, uniformly applying on yarn about 0.5 to 2.0 percent by weight based on the weight of the yarn a finish consisting essentially of 40 to 90 percent of a lubricant selected from the class consisting of mineral oil having a viscosity of about 8 to 25 centistokes at 25* C., an ester of a carboxylic acid having a chain length of about 12 to 18 carbon atoms with an alkyl alcohol having a chain length of about three to seven carbon atoms and mixtures thereof; 2 to 35 percent of a nonionic alkoxylated emulsifier and 5 to 30 percent of a lower alkanolamide of fatty carboxylic acid having a chain length of about eight to 18 carbon atoms as an antistatic agent, and then taking-up said yarn using a ring and traveller mechanism while inserting low real twist into said yarn in the opposite direction of said false twist.

Claim 15

The process of claim 12 wherein said yarn comprises nylon 6.

Claim 16

The process of claim 12 wherein said yarn comprises nylon 6, 6.
