Description

United States Patent r 2,763,578 PROCESS OF FINISHING CELLULOSIC FABRIC AND PRODUCT RESULTING THEREFROM John Kenson Simons, Norristown, Pa., assignor to Quaker Chemical Products Corporation, Conshohocken, Pa., a corporation of Pennsylvania No Drawing. Application March 24, 1954, Serial No. 418,462 6 Claims. (Cl. 117145) This invention relates to the finishing of fabrics in order to obtain special effects. In particular it relates to the application of polymeric products to impart various finishes, such as a taffeta finish, for example, to fabrics made of cellulose acetate and regenerated cellulose, such as cuprammoniu-m and viscose rayon.
Fabrics constructed completely or partly of these fibers made be soft and limp or stiff and firm depending on their construction. In order to obtain fabrics with increased stiffness and crispness from the softer construction, it is necessary to apply some kind of finish. For example, the crispness, stiffness, and scroop associated with taffeta-s may be imparted to a cellulose acetate fabric lacking these characteristics by the application of a taffeta finish. Even more stiffness and paperiness are demanded for utilization of the fabric as ribbon; this may be accomplished by applying a ribbon finish.
A ribbon or taffeta finish to be acceptable must impart to the fabric other properties besides crispness, stiffness, paperiness, or scroop. The finish must have such adhesion to the fiber that it does not show mark-off or dusting. It must undergo calendering, hot or cold, with no undesirable eifects on the hand of the fabric. It must not interfere with the cutting of the fabric by means of a hot knife or wire. It must withstand laundering and dry cleaning. It must impart a certain desirable gloss or sheen to the fabric and, obviously, it must not have adverse toxicological or dermatological effects.
Such finishes have in the past been provided by the application of resinous products of the alkyd type made by the condensation reaction of a polybasic acid, such as phthalic acid and polyhydric alcohols, such as glycerol. These resins are supplied and stored in very viscous alkaline solutions. Because of gradual saponification and other detrimental reactions which occur on storage/ these products deteriorate with aging and, therefore, the effects produced by these resins change with their age. In fact, upon prolonged storage, they lose their water solubility and become useless.
An object of the present invention is to provide a means of finishing cellulose acetate and other cellulosic fabrics with resins having much improved storage stability. These resins are addition polymers which are quite resistant to saponification and cannot undergo a gradual deterioration of the kind which takes place with alkyd type materials. Another object is to provide a means of finishing fabrics with polymers which are easily handled as low viscosity emulsions. A further object is to provide a finish with superior qualities in color, mark off, hand and permanence to atmospheric conditions.
A resinous product should possess certain qualifications to be useful for finishing fabrics. It is preferable to apply such resins from an aqueous solution whose viscosity must be low enough to allow for correct mechanical action of the fabric and the finishing machinery. Very few of the known resins which can be dissolved in aqueous media are suitable.
Interpolymers from various polymerizable monomers and polymerizable or unsaturated acids are well known.
Such products as the copolymers of styrene and maleic acid, vinyl methyl ether and ma-leic acid, methyl methacrylate and methacrylic acid have been described and 2,763,578 Patented Sept. 18, 1956 many of them have applications in the textile fields. But although these products have sufficient stability toward saponification, they have disadvantages which have prevented their utilization in certain finishing operations; viz., their solutions at concentrations low enough to give workable viscosities in the bath do not give the desired effect on the fabric and, vice versa, when the bath is made up to a concentration which would probably give the desired effects the viscosity is so high that the fabric cannot be run through it satisfactorily. A further disadvantage of using these products is that they are usually provided as granular or powdery solids which dissolve with difficulty in dilute ammonia or alkalies.
It has been found that finishes of exceptionally fine color and clarity, preserving the fine-st sheen or gloss of an acetate fabric and yielding fabrics with hand characteristics ranging through a heavy fullness: to a thin, crisp paperiness may be obtained by the processes of this invention. Such results are produced by employing an emulsion of an interpolymer of acrylic or methacrylic acid and at least two monomers selected from the group consisting of vinyl acetate, methyl methacrylate, methyl acrylate and ethyl acrylate. These interpolymers are composed of at least three components, e. g., vinyl acetate, an acrylic acid of the formula CH2=C(R)COOH wherein R is H or CH3, or mixtures thereof, together with an ester of such an acid and a lower aliphatic alcohol containing not more than 4 carbon atoms. The proportions of each may be varied within limits hereinafter described. In order that these resins may be applied from alkaline or ammoniacal aqueous solution a certain minimum amount of acrylic acid is desirable. It has been found that at least five mol percent based on the total monomer is necessary. The maximum amount that is desirable is dependent on the Water solubility of the resulting polymer. A maximum percentage which it is undesirable to exceed is 30 mol percent by Weight. The amount of acrylic acid ranges between 5 and 20 mol percent by Weight for satis factory results. Values of 7-10 mol percent by Weight are preferred. i
The choice of other monomers copolymerized with the acrylic acid and the proportions thereof depends upon the quality of the hand desired of the fabric. Vinyl acetate may be used with methyl acrylate or ethyl acrylate, for example, in the proportions by weight of mol percent vinyl acetate, 10 mol percent of methyl or ethyl acrylate and 10 mol percent acrylic acid. The vinyl acetate content in such terpolymers may vary, but should preferably not be less than 50% mol by Weight of the total polymer. The proportion of acrylic acid ester which is incorporated into these resins also may be Widely varied. Values of 5 to 20 mol percent by weight of the total monomer present have been found satisfactory. Seven to ten mol percent are the preferred values.
Interpolymers from acrylic acid or methacrylic acid and a polymerizable monomer are well known. Certain of these products, e. g., methacrylic acid-methyl methacrylate interpolymers, have been suggested for application to textiles as a size, more particularly as a warp size. These products are not suitable for taffeta or ribbon finish because their solutions, at concentrations low enough to give workable viscosities in the bath do not give the desired effects on the fabric. On the other hand, interpoly- Iners of vinyl acetate with acrylic acid have been found to lack sufficient crispness and stiffness when applied as a taffeta finish. Other polymers of various types which have been found to be unsatisfactory for these reasons are: vinyl acetate-maleic anhydride, methyl vinyl ether-maleic 'anhydride, styrene maleic anhydride, vinyl acetate-methyl from vinyl acetate, acrylic acid and vinyl propionate or vinyl Z-ethyl hexoate were found to yield finishes lacking in crispness and paperiness. Satisfactory terpolymers are obtained using vinyl acetate, acrylic or methacrylic acid Alternatively, the resin may be applied to fabrics without forming a solution. The diluted emulsion is applied without adjusting the pH to the alkaline side, using the usual methods of padding, nipping, drying, and calenderand the lower aliphatic esters of acrylic or methacrylic iiig. acid. For example, methyl or ethyl acrylate or methyl The following examples are given for illustrative purmethacrylate may be incorporated in terpolymcrs which poses and are not to limit the invention. yield satisfactory finishes.

Persons skilled in the art of finishing fabrics will appreciate the usefulness and versatility of this invention. It has already been shown how these polymers may be applied to fabric from an emulsion or from a solution formed by addition of ammonia. Other effects are possible by only partly neutralizing the emulsion, or by application with water-repellent compositions, softeners or fire retardant. The use of ammonia solutions results in the application of a resin finish which probably undergoes important changes on curing due to liberation of ammonia. The use of fixed alkalies or the addition of polyvalent salts or bases will give different results: the finish may be made permanently insoluble in Water or it may be given other permanent modifications.
