- the present invention relates to textile sizes. More particularly it relates to acid-modified poly(vinyl acetate-vinyl propionate) textile sizes and to textiles, especially polyester textiles sized with these materials.
- yarn is sized with an aqueous solution of a water soluble material such as a copolymer of vinyl acetate and a carboxylic acid, woven into cloth on a conventional loom with a mechanical shuttle and then the size is removed in a water bath. While these sizes have been adequate for natural textile fibers and for many of the synthetic textile fibers, they exhibit poor adhesion to synthetic fibers, particularly to polyester fibers which are enjoying increasing use in broadwoven textiles. Interpolymers of vinyl acetate and maleates have better adhesion to polyester but insufficient to prevent shedding from the yarn, leaving it unprotected from the destructive forces of the loom.
- a water soluble material such as a copolymer of vinyl acetate and a carboxylic acid
- Acrylate sizes have good adhesion to polyester but lack the strength to hold the monofilaments together sufficiently to withstand the disruptive forces of the loom. This weakness may be overcome in an unsatisfactory fashion by heavier coatings of size but costs rise because of the heavier consumption of size and more importantly, because of frequent interruptions to repair breaks of the warp caused by deposition and accumulation of size on the heddles and reeds of the loom.

FIELD OF INVENTION The present invention relates to textile sizes. More particularly it relates to acid-modified poly(vinyl acetate-vinyl propionate) textile sizes and to textiles, especially polyester textiles sized with these materials.
PRIOR ART In conventional loom operations yarn is sized with an aqueous solution of a water soluble material such as a copolymer of vinyl acetate and a carboxylic acid, woven into cloth on a conventional loom with a mechanical shuttle and then the size is removed in a water bath. While these sizes have been adequate for natural textile fibers and for many of the synthetic textile fibers, they exhibit poor adhesion to synthetic fibers, particularly to polyester fibers which are enjoying increasing use in broadwoven textiles. Interpolymers of vinyl acetate and maleates have better adhesion to polyester but insufficient to prevent shedding from the yarn, leaving it unprotected from the destructive forces of the loom. Acrylate sizes have good adhesion to polyester but lack the strength to hold the monofilaments together sufficiently to withstand the disruptive forces of the loom. This weakness may be overcome in an unsatisfactory fashion by heavier coatings of size but costs rise because of the heavier consumption of size and more importantly, because of frequent interruptions to repair breaks of the warp caused by deposition and accumulation of size on the heddles and reeds of the loom. Other sizes such'as poly(vinyl alcohols), styrene maleic anhydride copolymers, poly(acrylic acids) and gelatin are extremely poor in adhesion to polyester.
Thus, there exists in the art a need for a textile size with adequate adhesion to synthetic yarns and in particular to polyester yarn, and with improved physical properties such as tensile strength, elongation and toughness, and solubility in aqueous and organic media.
SUMMARY OF THE INVENTION The above-mentioned need in the prior art is fulfilled by the present invention which provides acid modified poly(vinyl acetate-vinyl propionate) textile sizes which, applied to the yarn as the salt of a monovalent cation, are suitable for use on conventional looms.
The textile sizes of the present invention have excellent solubility characteristics, film properties and adhesion to filament acetate, filament rayon and filament nylon and especially to filament and texturized polyester. Moreover, these sizes are easily removed from sized yarns or the resulting fabric using organic solvents, water or aqueous solutions of inorganic or organic monovalent bases.
It is, accordingly, one object of this invention to provide novel interpolymer latices which are especially useful in the sizing of textile warp yarns.
It is a further object of this invention to provide improved compositions for sizing textile yarns, especially polyester warp yarns.
yarns from mechanical damage during weaving and is readily removed from the yarns by a simple scouring in water.
It is a further object of this invention to provide sized textile warp yarns which are covered with a tough adherent and flexible sizing agent which protects the yarns from mechanical damage during weaving and is readily removed from the yarns-by extraction with organic solvent.
PREFERRED EMBODIMENTS The sizes of the present invention are prepared from latices obtained by interpolymerizing vinyl acetate, vinyl propionate and a variety of unsaturated organic carboxylic compounds containing from three to nine carbon atoms and having at least one carboxyl group.
Examples of such carboxylic acids include the unsaturated organic monocarboxylic acids, as for example acrylic acid, methacrylic acid, crotonic acid and isocrotonic acid. Further examples of unsaturated carboxylic acids include partial esters of unsaturated polybasic carboxylic acids, for example, the half esters of maleic acid, fumaric acid, citraconic acid and itaconic acid in which the alkyl group contains from one to four carbon atoms, such as methyl, ethyl, propyl and butyl maleates. Mixtures of these acids may be used in the preparation of the interpolymer latices.
In the preparation of an interpolymer latex, the poly merization charge comprises from 50 to 92 percent by weight of vinyl acetate, from 5 to 40 percent by weight of vinyl propionate and from 3 to 10 percent by weight of ethylenically unsaturated carboxylic acid, based on the total weight of the monomers. More preferably, the polymerization charge comprises from 69 to 86 percent of vinyl acetate, from 10 to 25 percent of vinyl propionate and from 4 to 6 percent of ethylenically unsaturated carboxylic acid. The upper limit of acid is set by latex stability; the lower limit by polymer solubility in aqueous base.
The monomers are polymerized using latex polymerization methods at a temperature in the range of from 40 to 60 C and preferably at a temperature in the range of from 40 to 45 C. At temperatures below about 40 C. the polymerization rate is too slow and the reaction mass tends to coagulate. At polymerization temperatures above 60 C. the product is of low molecular weight and lacks the tensile strength and elongation required in sizes. The interpolymerization product has a specific viscosity in the range from 1.2 to 12 and preferably 1.3 to 10, measured in dimethyl sulfoxide at a concentration of 1 gram interpolymer per ml. of solution at 25 C.
The interpolymerization is carried out using a surfactant which comprises a phosphate ester of an alkyl phenol-ethylene oxide condensate wherein the alkyl group contains from seven to l 1 carbon atoms. Especially preferred are the phosphate esters of tertiary octyl phenol-ethylene oxide condensates (hereinafter referred to as PEOPEO) and the phosphate esters of nonyl pheno- [ethylene oxide condensates (PENPEO). These preferred surfactants are available commercially as Triton XQS surfactants (Rohm and Haas Company) and GAFAC surfactants (General Aniline and Film Company), respectively. The amount of the phosphate ester of an alkyl phenol-ethylene oxide condensate used will be in the range of from 1.0 to 4.0 percent by weight based-on the total weight of the latex.
Preferably, the inte rpolymerization of the monomers is carried out using an anionic co-surfactant in combination with the phosphate esters of an alkyl phenolethylene oxide condensate. The use of the cosurfactants reduces the amount of coagulum in the resulting latex and provides a better product. The preferred co-surfactants used in the present invention include alkyl sulfonates such as sodium dodecyl benzene sulfonate; fatty alcohol sulfates such as sodium lauryl sulfate; dialkyl sulfosuccinates such as sodium dihexyl sulfosuccinate; etc. The amount of co-surfactant used is in the range of 0.1 to 0.4 percent by weight and more preferably 0.20 to 0.30 percent by weight based on the total weight of the latex.
The polymerization processes are initiated by a two component redox free radical initiator system. Suitable oxidizing components for the system are the inorganic peracid salts such as ammonium, potassium and sodium persulfates, perborates, and hydrogen peroxide. Preferred, however, are the oil soluble organic hydroperoxides such as t-butyl hydroperoxide, cumene hydroperoxide, p-menthane hydroperoxide, etc. and esters of the t-butyl perbenzoate type. The useful reducing components include compounds like the sulfites, bisulfites, hydrosulfites and thiosulfites; ethyl and other alkyl sulfites; the sulfoxylates, such as sodium formaldehyde sulfoxylate; and the like. Especially preferred are initiator systems based on t-butyl hydroperoxide and sodium formaldehyde sulfoxylate; and redox combinations such as mixtures of hydrogen peroxide and an iron salt, hydrogen peroxide and zinc formaldehyde sulfoxylate or other similar reducing agent; hydrogen peroxide and a titanous salt; potassium persulfate and sodium bisulfite and a bromate mixed with a bisulfite.
The use of equimolar amounts of initiator system components is generally preferred although the amount of each component as well as the total amount of catalyst used depends on the type of component used as well as on other polymerization conditions and may range between .02 and 0.2 percent by weight of the total polymerization system, the preferred range being 0.03 to 0.10 percent for the oxidizing component and 0.04 to 0.1 for the reducing component.
The solids contents of the latices can be varied over a wide range. The preferred latices having a solids content in the range of from 15 to 65 percent by weight and more preferably from 35 to 55 percent by weight, based on the total weight of the latex.
During the polymerization reaction a conventional base such as ammonium hydroxide or sodium hydroxide is used to buffer the latex to a pH in the range of 4.0 to 6.0. I
The textile size solution may be prepared from the latex in several ways. ln one method, an aqueous solution of base is mixed with the latex to dissolve the interpolymer by formation of the water soluble interpolymer carboxylate. Suitable bases include the hydroxides, carbonates and bicarbonates of alkali metals and alkaline earth metals such as sodium hydroxide, sodium carbonate and sodium bicarbonate; ammonia, organic bases such as methylamine, dimethylamine, trimethylamine, ethylamine, diethylamine, triethylamine, morpholine, etc. The preferred base in the preparation of a loom finish size is ammonium hydroxide since it contributes to good adhesion and resistance to water, water spotting and dry cleaning. The preferred base in the preparation of removable warp yarn size is sodium carbonate since it contributes to rapid solution of the interpolymer, good adhesion of the interpolymer size especially to polyester yarn and rapid removability of the size. A particular advantage of an interpolymer latex is that the fine size of the interpolymer particles allows rapid solubilityof the interpolymer in aqueous base to form the size solution.
Another method for preparation of the textile size solution comprises the recovery of the interpolymer from the latex by conventional means and solution of the interpolymer in an organic solvent. The size is then applied to the textile yarn as an organic solution and may be removed from the woven goods with aqueous base or organic solvent.
Preferred organic solvents for preparation of size solutions and removal of size are alcohols, ketones, esters and aromatic solvents.

Tensile strength and elongation are measured according to ASTM Method D-882-67 on interpolymer neutralized with sodium carbonate, after conditioning at 65 percent relative humidity.
Adhesion values are the loads in pounds required to break /2 X A inch polyester lap joints adhered with 0.15 mil film of interpolymer. Experience has shown that an adhesion value of at least 30 pounds is required for satisfactory size performance with filament polyester on a commercial machine.
The vinyl propionate level is varied between 0 and 30 percent. Interpolation of the data in Table I indicates that adhesion values would be unsatisfactory with interpolymers containing less than 10 percent vinyl propionate. On the other hand, high concentrations of vinyl propionate in the interpolymer contribute to coagulation of the latex and to low molecular weight, low cohesive strength and tackiness of the polymeric size.
