18 Claims. (01. act-29.6)
This invention relates to an improved warp size and to a method of preparing the same, as well as to a method of treating textile material, especially yarns made from synthetic fibers such as regenerated cellulose and cellulose acetate,
with said size.
It is common practice to treat yarns, intended to be woven as warps, with an aqueous solution of an adhesive or binding substance such as starch, modified starch products, e. g., thin boiling starch, soluble starch, and dextrine, natural gums, e. g., locust bean gum, and gum arable or animal or vegetable proteins, e. g., glue, gelatin, casein, soya bean and peanut protein.
It is customary to apply this sizing at the The yarn, in sheet form, is immersed in the size solution, nipped once or twice between heavy metal rolls covered with flannel cloth or rubber, and then dried over steam heated cans, or in hot air boxes.
Warps so sized with starch, modified starch or natural gums tends to dust excessively when the threads are split open and separated one from the other in front of the slasher before they are wound on the loom beam. They also lose a substantial part of the size film when subjected to the friction and abrasion concomitant with the weaving operation. When this dusting is excessive, as often happens, the warps lose their stiffened character and weaving efflciency is adversely affected.
Sizes made from proteins show a greater adhesion to the fibers, and dusting is not as bad with those as with the starch size. These sizes, however, have a tendency to thicken and jell on cooling. Consequently the viscosity of the size solution is subject to wide variations on slight Furthermore, protein sizes have the disadvantage of being subject to decomposition and putrefaction.
' It has recently been suggested to employ, for the-finishing of textile fabrics, aqueous solutions cf'the sodium or ammonium salts of copolymers of styrene and maleic anhydride. The use of such salts has an important disadvantage in that it is necessary, to obtain satisfactory aqueous solutions thereof, to react with the styrene- ,maleic anhydride copolymer an amount ofalkali metal or ammonium hydroxide or carbonate sufiicient to raise the pH to or above. Such a high pH in a size solution is undesirable, especially in lthetreatment of yarns made from cellulose acetate, because a pI-I higher thanabout 8.01 8.5 may easily cause superficial saponification and her y change tneciye ns; nmnert e 9f t ra It is a primary object of the present invention to provide a warp size that is substantially free from dusting, has greater afiinity for natural and synthetic fibers, possesses greater stability and uniformity of viscosity, and is absolutely free of any tendency to decompose or putrefy.
The size of the present invention is an aqueous solution of an alkaline, water-soluble boron salt reacted with a copolymer of styrene, or a substituted styrene such as methyl styrene, butyl styrene, chlorostyrene or the like, with maleic anhydride or a partially esterified maleic anhydride such as the half ester of butyl maleate.
This size is substantially free from dusting, has excellent affinity for natural and synthetic fibers, possesses superior stability and uniformity of viscosity, and does not decompose or putrefy. Furthermore, completely satisfactory solutions in water are obtainable at pH values of the order of '1 to 7 .5.
While it is to be understood that the invention is not to be limited by any theory advanced herein, it is believed that the remarkable difference between the sodium and ammonium salts and the boron salts of the styrene-maleic anhydride copolymers is essentially due to the effectiveness of the boron-oxygen group in bringing about a strong crossbonding of the copolymers molecular chains and thereby increasing the intrinsic viscosity, continuity and strength of the film.
The copolymers used in forming the size of this invention are well known products which may be prepared in several ways, e. g., either by heating together the two components or by reacting them in the presence of a mutual solvent and a catalyst. The copolymers so produced are not soluble in Water, but form water soluble salts of alkali metals, ammonium hydroxide, and organic bases such as triethanolamine, morpholine, etc.
Any of the water-soluble, alkaline boron salts may be used for reaction with the copolymer in accordance with this invention. These include sodium borates, such as: 1
Sodium metaborate- NaBOz (or Na2B2O i) NaBOz 21-120 (or NaI-IzBOs H20) Sodium tetraborate Na2B4O'1 Nazi-3407 5H2O Na2B4O7-10H2O (borax) Sodium perborate- NaBQz-Hzo (or NaBOz-HzOz) x NaBO3-4HzO (or NaBO2'H2O2'3H3Ol3 M 3 as well as corresponding potassium, lithium and ammonium salts, such as:
Potassium metaborate, KBOz (or K2B204) Potassium tetraborate, K2B407'5H2O Potassium pentaborate, K3508 Potassium perborate, KBOa- /2H2O Lithium metaborate-- LiBOz LiBOz-8H2O Lithium tetraborate, Li2B4O7-5H2O Ammonium perborate- NH4BO3 (r NH4BO'3- /zH2O) Ammonium tetraborate- NH4HB4O7'3H2O Ammonium pentaborate-- The proportion of the reacting components is determined partly by the acid value of the copolymer of styrene and maleic anhydride, and partly by the relative alkalinity of the boron salt. The amount of boron salt should be sufiicient to give -a pH of about 7 to 7.5 to a suspension of the copolymer and salt in water. The addition of more boron salt serves no useful purpose. Ordinarilythe ratio, by weight, of copolymer to boron salt varies between about 1:1 and 2:1.
The size solution of this invention is prepared by blending the copolymer with the boron salt and any other additional ingredients referred to more specific-ally hereinafter, dispersing the resulting dry size blend in water, heating the dispersion to a temperature of about 190 to 200 F., and maintaining it at about that temperature until the powder is completely dissolved.
Size solutions thus prepared can be kept indefinitely without spoilage or decomposition.
It is within the contemplation of the invention to add to the size solution other ingredients in order to alter, as the need may be, or improve the adhesive, plastic and penetrating qualities of the size bath.
As plasticizer for the sizing film such material glycerine, ethyleneor diethylene glycol, sorbitol, urea, etc., can be used. Urea is preferred because it imparts to the sizing film excellent flexibility without reducing the adhesive properties, or dangerously increasing the hygroscopic absorption of moisture, especially in the case of yarns made from regenerated cellulose.
The amount of plasticizing agent can be varied, depending upon the type of fiber and the relative humidity of the weave room, :from 5% to 25% by weight of the dry size blend.
As the commercial powdered copolymer of the styrene and maleic anhydride is very flufi'y, light, and dusty, it is desirable that it be sprayed with a small amount, e. g., 2% to 5% by weight of the dry size blend, of light mineral oil. Typical among such light oils are kerosene and oils available commerce under the trade names Amsco- Solv. F, Bayol, etc.
Also due to its lightness and fiuffiness, the styrene-m-aleic anhydride copolymer is very hard to wet out and mix with water. For this reason it is desirable also to add to the mixture a small percentage (.-5% to 5%) of a wetting-out agent such as soluble pine oil, sulfonated oil, and sulfated long'chain alcohols. This may be mixed or dissolved in the mineral oil and sprayed at the same time.
The following examples illustrate several of the preferred embodiments of the invention:
Example 1 The following materials were blended together, the parts being by weight:
46% styren-e-maleic anhydri-de copolymer 26% borax 20 urea 3% pine oil (Hercules Powder Co., Yarmor 302") 5 light oil (Amsc-o Solvent F) 100 lbs. of this dry blend were dispersed in 1200 lbs. of water and the mixture heated to LBW-200 F. and kept at this temperature until the powder was completely dissolved. The resultant pH of the solution was between '7 and 7.5.
Cellulose acetate warps sized with this solution had excellent weaving qualities, there was no dusting in the sizing machine or in the loom. The size solution can be kept indefinitely without spoil-age or decomposition.
Example '2 The following materials were blended together,
the parts being by weight:
41% styrene-maleic anhydride copolymer 33% sodium metaborate (NaBO2-2H2O) 20% urea 3% pine oil (Y-armor 302") 3% Bay-oi mineral oil 60 lbs. of this dry blend were dispersed in 1200 lbs. of water and the mixture heated to l-200 F. and kept at this temperature until the powder was completely dissolved. The resultant pH was between '7 and 7 .5.
Regenerated cellulose warps sized with this solution had excellent weaving qualities, there was no dusting in the sizing machine or on the loom. The size was removed completely from the woven cloth in a bath of plain warm water, there was no need to use enzymes, or any other desizing agent, as is necessary with starch and gelatine.
Example 3 *The following materials were blended together, the parts beingby weight:
49% styrene-maleic anhydride copolymer 39% sodium metaborate (NaBOz-QHzO) 6% glycerine 3% pine oil (Y'armor 30 2) 3 light oil (Amsco Solvent F) lbs. of this dry blend were dispersed in 1000 lbs. of water and the mixture heated to -20Q F. and kept at this temperature until the powder was completely dissolved. The resultant pH of the solution was between 7 and 7.5.
Warps made from spun yarns of cellulose acetate and wool blended together and sized with this solution had excellent weaving qualities. There was very little dusting in the sizing machine, and much less than with other ordinary sizing materials in the loom. The sizing solution can be kept indefinitely without spoilage or decomposition.
It is to be understood all such modifications and changes in the components, proportions and procedures described as will readily occur to those skilled in the art upon reading this description are intended to be included within'the scope of the invention as definedin the accompanying claims.
