Cellulosic textile yarns are sized with a combination of a permanent polymer, a temporary polymer and a crosslinking agent prior to weaving. The permanent polymer includes polyurethanes, polyacrylates, butadiene-styrene copolymers, butadiene-acrylonitrile copolymers, and ethylene-vinylacetate copolymers. A temporary polymer is polyvinyl alcohol. Crosslinking agents include dimethylol dihydroxy-ethylenurea (DMDHEU), dimethylol methoX- yethylcarbamate, methylol melamine, and dimethylol propyleneurea.
This is a continuation-in-part of Ser. No. 756,323 filed Aug. 29', 1968, now abandoned.
A non-exclusive, irrevocable, royalty-free license in the invention herein described, throughout the world for all purposes of the United States Government, with the power to grant sublicenses for such purposes, is hereby granted to the Government of the United States of America.
The primary object of this invention is to provide a method for producing durable-press fabrics with superior abrasion resistance. In this method, textile fibers and crosslinking agents are sized with a combination of permanent polymer additive, temporary polymer agent and crosslinking agent prior to weaving. The polymer additive employed is one which improves the wrinkle recovery or abrasion resistance when applied to woven fabric. By application of the polymer additive to the yarn, prior to weaving, the polymer additive serves the dual purpose of acting as a weaving size and improving the wrinkle recovery of the finished fabric. The use of a crosslinking agent in conjunction with the temporary sizing agent provides a method by which the temporary agent becomes permanently attached to the fabric. By use of the crosslinking agent in the size, a less than normal amount of crosslinking agent can be utilized in finishing the fabric subsequent to weaving. This procedure provides a method of producing fabrics with smooth drying appearance and improved abrasion resistance.
Heretofore sizing mixtures have been designed to be temporary and are removed by desizing operations immediately after weaving. Permanent polymers are then applied to the fabric. Polymers applied to the fabric tend to stiffen the fabric and at times lead to undesirable yarn binding. This higher degree of stiffness is detrimental from the viewpoint of the esthetics of the fabric to the wearer as well as abrasion resistance in the garment manufactured from such fabrics.
By the process of this invention, polymers and crosslinking agents can be applied to yarns in the normal manner that starch size is applied. The types of polymers which have been successfully utilized have been polyurethanes, polyacrylates, and butadiene-styrene copolymers. The types of temporary sizing agents used in this research include polyvinyl alcohol and carboxymethyl cellulose. The types of crosslinking agents used include dimethylol dihydroxyethyleneurea and methylol melamines. The warp yarn is passed through the emulsion, squeezed, and dried and cured in some cases. The resulting warp beam is then loomed and woven into a fabric. The woven fabric can be scoured, bleached, and dyed. Durable-press crosslinking agents and other finishing auxiliaries are then padded onto the fabric and dried.
The advantages of using permanent polymer sizing are many. Polymers can be applied to the yarns in the normal manner that starch size is applied at the slasher. This. eliminates the desizing procedure normally encountered in the application of a temporary sizing. Efficiency in weaving is equal to or better than regular starch size. It is also possible to vary the conditions of sizing. For example, you can use permanent sizing in warp and filling, permanent sizing in the warp direction only, or a combination of permanent and temporary sizing. Another advantage of applying the permanent polymer to the yarn and then weaving the fabric in contrast to application of the polymer to the woven fabric is that the resultant yarn treated fabrics are softer than the fabrics treated with the same polymer add-on. This reduced stifiness improves edge abrasion resistance. Durable-press fabrics, which have polymers only in the warp direction, do not have the exceedingly low crease sharpness values exhibited by fabrics which have been treated with the same polymers as fabric treatments.
Yarns can be sized with a combination of temporary and permanent sizing agents. This type formulation has cost advantages over the use of permanent sizing agents only. Under certain conditions temporary agents such as PVA/CMC can be crosslinked to produce fabrics with excellent durable-press performances and a substantial improvement in fabric strength properties.
In this method, textile fibers/yarns are sized with permanent polymers and combinations of these ingredients with crosslinking resins. This method produces good durable-press fabrics with low resin concentrations; thus improving physical properties with cost saving finishes. Directional application of polymer and crosslinking agents can be used to control physical properties, wrinkle recovery, and abrasion resistance of a preferred yarn direction in the finished fabric.
Other variations to this same basic treatment are also possible. A brief description and explanation of these variations will be given.
First, it is possible to prepare fabrics from polymer sized warp and filling yarns, and it is also possible to prepare fabrics from yarns treated with a combination of polymers and crosslinking agents. If the same polymer and crosslinking agent are used for both the warp and filling treatment, the resultant fabric is softer than the fabric treated with the same polymer. The yarn-treated fabrics then can be raised to durable-press performance with a lower level of crosslinking treatment or an equivalent level of crosslinking treatment. The yarn-treated fabric is softer and has improved abrasion resistance.
In a second variation, yarns were sized with one polymer in the warp direction and a second polymer in the filling direction. No such fabric can be produced from a fabric treatment and the types of polymers used for the warp and filling treatments can be used to control or modify final properties such as breaking strength, crease sharpness, fabric stiffness and other properties.
A special variation of sized warp and filling yarn fabrics can be employed to achieve certain unique fabric properties. Thus, it was found that heavyweight fabrics prepared from warp and filling polymer-treated yarns (particularly 2-ply yarns) can be used to produce a fabric which has good wash-wear appearance with no further treatment other than application of a softener. Cuffs prepared from such fabrics showed good wash-wear appearance and crease sharpness through 30 launderings. The

We claim:
1. A process for producing a durable-press fabric with superior abrasion resistance comprising:
(a) treating cellulosic textile warp and filling yarns with an emulsion consisting of about from 4% to 20% by weight of a permanent polymer selected from the group consisting of polyurethanes, polyacrylates, butadiene-styrene copolymers, butadieneacrylonitrile copolymers, and ethylene-vinylacetate copolymers, about from 1% to 20% by weight of a crosslinking agent selected from the group consisting of dimethylol dihydroxyethyleneurea, dimethylol methoxyethylcarbamate, dimethylol propyleneurea, and methylol melamine, and about from 0.5 to 1.5% by weight of a base catalyst, and drying and curing the thus-treated yarns;
(b) weaving a fabric from the treated, dried, and cured yarns of steps (a); and
(c) crosslinking the woven fabric from step (b) with about from 1% to 20% by weight of a crosslinking agent selected from the group consisting of methylol dihydroxyethyleneurea, dimethylol methoxyethylcarbamate, dimethylol propyleneurea, and methylol melamine.
2. A process for producing a durable-press fabric with superior abrasion resistance comprising:
(a) treating cellulosic textile warp and filling yarns with an emulsion consisting of about from 1% to by weight of polyvinyl alcohol, about from 1% to by weight of a crosslinking agent selected from the group consisting of dimethylol dihydroxyethyleneurea, dimethylol methoxyethylcarbamate, dimethylol propyleneurea, and methylol melamine, and about from 0.5% to 1.5% by weight of zinc nitrate base catalyst, and drying and curing the thus-treated yarns;
(b) weaving a fabric from the treated, dried, and cured yarns of step (a); and
(c) crosslinking the woven fabric from step (b) with about from 1% to 2% by weight of a crosslinking agent selected from the group consisting of dimethylol dihydroxyethyleneurea, dimethylol met-hoxyethylcarbamate, dimethylol propyleneurea, and methylol melamine.
3. A process for producing a durable-press fabric with superior abrasion resistance comprising:
