Definitions
- R represents an alkylene bridge group necessary to complete a 5,6 or 7-membered heterocyclic ring system
- R represents either hydrogen or a methyl group
- n represents a number indicative of the extent of polymerization and is usually at least 3 or 4
- This invention relates to a process for rendering thermoplastic fiber-containing textile materials normally succeptible to snag, picking, and pull damage, resistant to such damage.
- the process includes contacting said material with a pad bath emulsion containing a poly (N-vinyl lactam)'graft copolymer.
- Knitted fabrics particularly those of double knit construction and/or those employing texturized yarn, show a tendency to snag or pull. Snagging is a particulaly acute problem in mens clothing where the retail price of the goods is quite high and a garment repeatedly damaged by snagging eventually becomes unattractive and/or unwearable and thus makes the price-life of the garment prohibitive.
- Poly acrylates as above-employed also have other drawbacks, including a stiff hand when the surfactant is leached out of the emulsion during washing of the treated material; lack of moisture regain after washings and the like.
- the emulsion additive" of the instant invention is not chemically the same nor does it function as an adjunct to improve hand" and abrasion resistance of resin treated textiles.
- the instant emulsion will not be applied along with permanent press" finishes to modify hand or improve abrasion resistance of said pemanent press finishes.
- the instant emulsion is therefore not employed as an additive or coreactant in the production of durable press garments produced by the application and subsequent curing of thermosetting resins to the fabric.
- the emulsion therefore is not employed in the endeavor to improve the abrasion rsistance of such fabrics as said term is known in the art.
- Improving the abrasion resistance of durable press resin treated textiles refers to the wear that occurs at the sleeve cuffs, pant cuffs and shirt collar. Said term does not generically include snagging and pulling as is known in the art to occur specifically to knitted materials, double knits and warp knits-of polyester, acrylates and nylon materials. Accordingly, where knitted articles, particularly those of double knit construction, have shown a tendency to snag on sharp or pointed objects, treatment with a durable press resin finish cannot be employed to prevent snagging and pulling, notwithstanding the fact that other resin treated fabrics might be more resistant to abrasion by treatment therewith.
- thermoplastic fibers normally susceptible to snag, picking and pull damage less susceptible thereto while still retaining excellent hand" and stretch characteristics.
- thermoplastic fiber containing textile material so treated.
- thermoplastic fiber-containing materials more resistant to picking, snagging and pulling, comprising treating same at a temperature between about 50F and l25F with an aqueous emulsion containing approximately by weight (I) 5 to 15% of a graft copolymer of a poly(N-vinyl lactam) having an average molecular weight between about 400 and about 2,000,000 and having the formula CH CH2 wherein R represents an alkylene bridge group of 2 to 4 carbon atoms necessary to complete a 5,6 or 7- membered heterocyclic ring system, R, represents either hydrogen or an alkyl group, and n represents a number indicative of the extent of polymerization, having graft polymerized thereon at least one member derived from the group consisting of C alkylacrylate esters, acrylic acid and an N-alkylol acrylamides or methacrylamides, said graft copolymer having a weight ratio of

- polymeric N-vinyl lactams are commercially available and called polymeric N-vinyl lactams.

Depending upon the extent of polymerization, they have molecular weights ranging from at least 400 up to 2,000,000 or more. Viscosity measurements are commonly used as an indication of the average molecular weight of polymeric compositions the instant polymers being characterized by a chain of carbon atoms to which the lactam rings are attached through their nitrogen atoms:
- the K value (Fikentscher) of any particular mixture of polymers is calculated from viscosity data and is useful as an indication of the average molecular weight of such mixture. its determination is fully described in Modern Plastics, 23, No. 3, l576l,2l2,2l4, 216, 218 (I945), and is defined as 1000 times k in the empirical relative viscosity equation:
- C is the concentration in grams per hundred cc. of polymer solution and "rel is the ratio of the viscosity of the solution to that of pure solvent.
- the K values are reported as I000 times the calculated viscosity coefficient in order to avoid the use of decimals.
- polymeric N-vinyl lactams having a K value of about 10 to 200, preferably of 30 to 100 because of their viscosity at lower concentrations.
- Relative viscosity, specific viscosity and K are dimensionless, whereas inherent viscosity (log M C and intrinsic viscosity (the limit of inherent viscosity as C approaches zero) have the dimensions of dilution, i.e., the reciprocal of concentration. lntrinsic viscosity and K are intended to be independent of concentration.
- n The number of recurring polymer units enclosed by brackets in the foregoing general structural formula, indicated by n, or the extent of degree of polymerization, corresponds to a chain of roughly 4 to 20,000 monomer units or more. ln actual practice, a mixture of polymeric molecules, each containing a different number (n) of monomer units, is produced.

- materials are allowed to dry after treatment with the above described emulsion and extraction for a sufficient period of time to effect the partial cure of this polymeric material.
- the final result is a finished fabric having a desirable hand, light fasteness, durability and other good fabric qualities. These and other properties may be determined by tests known in the trade. It is to be understood that the emulsion is equally as effective on warp knit and stretch wovens as it is on double knit polyesters. Also included are the Ban-Ion" texturized nylon fabrics and Acrilon" acrylate fabrics as well as rayonpolyester blends.
- the mixture was agitated, purged with nitrogen and heated to C over a 30 minute period. At this time a mildly exothermic reaction ensued and cooling was necessary.
