Abstract
A fiber finish composition, a method of formulating the same, a process for treating yarn therewith and yarn so treated are all disclosed. The fiber finish composition, which is applied as an overfinish to the yarn after drawing of the yarn, comprises about 24 to 86.4 weight percent of water, about 10 to 50 weight percent of a stiffener selected from the group consisting of triazines, melamine and urea-formaldehyde resins, about 3 to 20 weight percent of a water soluble lubricant, about 0.4 to 5 weight percent of a catalyst for the stiffener, and about 0.2 to 1 weight percent of a wetting agent. Polyester yarn so treated and woven in the filling direction to form a seat belt stiffens, or reduces the pliability of, the belt to inhibit curling of the belt in the retractor housing.

A synthetic filamentary yarn comprised of polyester filaments which are treated with from about 1.2 to 7.0 weight percent based on the weight of the yarn of a liquid composition comprising about 24 to 86.4 weight percent of water, about 10 to 50 weight percent of a stiffener selected from the group consisting of triazines, melamine, and urea-formaldehyde resins, about 3 to 20 weight percent of a water-soluble lubricant, about 0.4 to 5 weight percent of a catalyst for the stiffener, and about 0.2 to 1 percent of a wetting agent.
A synthetic filamentary yarn comprised of polyethylene terephthalate filaments which are treated with from about 2.5 to 3.0 weight percent based on the weight of the yarn of a liquid composition comprising about 24 to 86.4 weight percent of water, about 10 to 50 weight percent of a modified melamine urea resin, about 3 to 20 weight percent of a polyalkylene glycol ether, about 0.4 to 5 weight percent of an aqueous solution of magnesium chloride, and about 0.2 to 1 weight percent of a salt of dinonyl sulfosuccinate.
A fiber finish composition, particularly for application to polyester yarn prepared by a process involving spinning and drawing steps, said composition comprising:
- about 24 to 86.4 percent of water, about 10 to 50 weight percent of a stiffener selected from the group consisting of triazines, melamine and urea-formaldehyde resins, about 3 to 20 weight percent of a water-soluble lubricant, about 0.4 to 5 weight percent of a catalyst for the stiffener, and about 0.2 to 1 weight percent of a wetting agent, said composition being applied as an overfinish to the yarn after drawing the yarn.
A fiber finish composition, particularly for application to polyethylene terephthalate yarn prepared by a process involving spinning and drawing steps, said composition comprising:
- about 24 to 86.4 weight percent of water, about 10 to 50 weight percent of a modified melamine urea resin, about 3 to 20 weight percent of a polyalkylene glycol ether, about 0.4 to 5 weight percent of an aqueous solution of magnesium chloride, and about 0.2 to 1 weight percent of a salt of dinonyl sulfosuccinate, said composition being appllied as an over-finish to the yarn after drawing the yarn.
In a process for the production of a woven fabric wherein the cords of at least one weaving direction of the fabric are made from a polyester yarn, the yarn being prepared by a process involving spinning and drawing steps, the improvement which comprises:
- (a) treating the yarn subsequent to the drawing step with from about 1.2 to 7.0 weight percent based on the weight of the yarn of a liquid composition comprising about 24 to 86.4 weight percent of water, about 10 to 50 weight percent of a stiffener selected from the group consisting of triazines, melamine and urea-formaldehyde resins, about 3 to 20 weight percent of a water-soluble lubricant, about 0.4 to 5 weight percent of a catalyst for the stiffener, and about 0.2 to 1 weight percent of a wetting agent;
- (b) twisting the yarn into cord;
- (c) weaving a fabric which utilizes the treated cords in at least one weaving direction;
- and
- (d) exposing the fabric for an effective time period to a temperature which causes the composition to stiffen the fabric.
In a process for the production of a woven fabric wherein the cords of at least one weaving direction of the fabric are made from polyethylene terephthalate yarn, the yarn being prepared by a process involving spinning and drawing steps, the improvement which comprises:
- (a) treating the yarn subsequent to the drawing step with from about 2.5 to 3.0 weight percent based on the weight of the yarn of a liquid composition comprising about 24 to 86.4 weight percent of water, about 10 to 50 weight percent of a modified melamine urea resin, about 3 to 20 weight percent of a polyalkylene glycol ether, about 0.4 to 5 weight percent of an aqueous solution of magnesium chloride, and about 0.2 to 1 weight percent of a salt of dinonyl sulfosuccinate;
- (b) twisting the yarn into cord;
- (c) weaving a fabric which utilizes the treated cords in at least one weaving direction;
- and
- (d) exposing the fabric for about 1 to 1.5 minutes to a temperature of at least about 171.degree. C. (340.degree. F.) to cause crosslinking of the resin which stiffens the fabric.
