- hydrocarbons such as sodium alpha-naphthalene monosulfonate; condensation products of naphthalene sulfonic acids with formaldehyde; sodium octahydro anthracene sulfonate; alkali metal alkylsulfates; ether sulfates having alkyl groups of eight or more carbon atoms such as sodium lauryl ether sulfate; and alkylaryl sulfonates having one or more alkyl groups of eight or more carbon atoms such as hexadecylbenzene sulfonic acid and C 20 alkylbenzene sulfonic acid.
- Additional optional components of the curable composition of the invention include minor amounts of one or more organic solvents such as monohydric and polyhydric alcohols (when aqueous emulsions of curable and cured compositions are employed as described above), pH buffering agents such as strong or weak acids, e.g., HC1, H 2 S0 4 , phosphoric, benzoic or citric acid (the pH of the compositions are preferably less than 5.0), rewetting agents, viscosity modifiers such as electrolytes, for example, calcium chloride, anti- gelling agents, fragrances, fragrance carriers, fluorescers, colorants, hydrotropes, antifoaming agents, anti-redeposition agents, enzymes, optical brightening agents, opacifiers, stabilizers such as guar gum and polyethylene glycol, anti-shrinking agents, fabric crisping agents, anti- spotting agents, soil-release agents, germicides, fungicides, biocides, anti-oxidants, anti- corrosion agents,
- These and other optional components can be incorporated in the copolymer-forming composition in known and conventional amounts.
- the optional components can be incorporated in one or more of the aforementioned individual reaction component units to be later combined to provide the copolymer-forming composition herein (with due attention to storage stability concerns) or they can be added individually, in various sub-combinations or all at once when several optional components are utilized during or after the combining and mixing operation resulting in the fully formulated copolymer-forming composition.
- the amount of water used in the preparation of aqueous emulsions of macromonomers (i) and (ii) should be adequate to provide either an oil-in-water emulsion or a water-in-oil emulsion of good stability.
- the amount of water can be in the range of from about 20 parts by weight (pbw) to about 2000 pbw, preferably from about 100 pbw to about 500 pbw, per 100 pbw of the total amount of monomers (i) and (ii).
- Fully formulated curable compositions of this invention can be prepared by merely mixing and agitating macromonomers (i) and (ii), catalyst(s) (iii) and optional additional component(s) (iv) with a stirrer, e.g., a homogenizer.
- the components of the copolymer-forming composition can be introduced together into a vessel in a specific amount or as a pre-mixture of macromonomers (i) and (ii), catalyst(s) (iii) and optional component(s) (iv) followed by the addition of water.
- aqueous emulsion of curable composition of the oil-in-water or water-in-oil type is readily and conveniently obtained to provide the cellulosic textile-treating composition herein.
- the length of time for agitation depends upon the balance of the interfacial properties between the components of the curable composition including any optional surfactant(s) (iv) and water.
- Table 1 below sets forth suitable broad and preferred ranges for each of monomers (i) and (ii), catalyst(s) (iii) and optional components such as surfactants (iv), water, etc., for the copolymer-forming composition of the invention.
- Table 1 Weight Ranges of Components of the Curable Textile-Treating Composition As a Percent of the Total Composition
- textiles for treatment herein include nylon (polyarnides), polyester, wool, cotton, flax, hemp, jute and ramie, and the like, including blends of any of the foregoing with one or more other natural or synthetic fibers.
- cotton and wool can be blended with fibers derived from polyesters, polyarnides (e.g., nylons), acrylics (e.g., polyacrylonitrile), polyolefins, polyvinyl chloride, and polyvinylidene chloride.
- the textiles based on blends of fibers include at least 35 to 40 percent by weight, and most preferably at least 50 to 60 percent by weight, of cotton or other cellulosic fiber.
- the curable cellulosic textile treating composition of the present invention advantageously containing one or more surfactants (iv) as described above, can be diluted with water to a desired active level and applied to a fiber or textile by any suitable means such as spraying, dipping, padding, kiss roll, and the like. Removal of any treating composition can be achieved by using a mangle, centrifugal separator, or the like, to control the amount of liquid absorbed by the textile. Drying can be effected with or without heat. Depending upon the particular textile being treated, when drying is performed by application of heat, the drying temperature can generally range from 70° to 130°C and its duration from 1 to 30 minutes. After removal of any excess emulsion, subsequent heating to complete curing is usually required.
- Effective curing temperatures generally range from 130°C to 200°C for periods of from 1 to 30 minutes.
- the cured resin(s) impart one or more advantageous properties to the treated textile, e.g., shrink resistance, wrinkle resistance and/or desirable hand feel characteristics.
- the amount of aqueous emulsion of curable composition that a treated textile absorbs will generally range from 0.1 to about 5 weight percent based on the total weight of macromonomers (i) and (ii). It may be desirable to prepare emulsified reaction component units having higher macromonomer contents in order to reduce shipping and/or handling costs and then to dilute the emulsions with water immediately prior to use.
- macromonomer contents of the curable composition herein can range from 10 to 80 weight percent, preferably from 20 to 40 weight percent, based on the total weight of the
- Examples 4 to 6 illustrate the preparation of three different macromonomers (ii) and Examples 7-9 illustrate the preparation of three different catalysts (iii). In these examples, all indicated percents and parts are by weight.
- octamethylcyclotetrasiloxane (D 4 ) was charged to the vessel and mixed for 50min under high agitation (600rpm). The pre-emulsion was homogenized with the first pressure 50kg and the second pressure 500kg to provide an emulsion. Thereafter catalyst (2.0% of an aqueous solution of 10% KOH in water) was charged into the vessel. The vessel was then slowly heated to 80°C for 5 hours, and then the temperature was decreased to 45°C and maintained for 12 hours. Thereafter, 0.2% of acetic acid was charged to neutralize the solution.
- 16 parts of a silanol terminated polysiloxane (viscosity: 40,000 cps) was mixed with 8 parts TERGITOL TMN-6 and then 76 parts water was added slowly at 800-1000 rpm to form a homogeneous mixture.
- catalyst (2.0% of an aqueous solution of 10% KOH in water) was charged into the vessel.
- the vessel was then slowly heated to 80°C for 5 hours, and then the temperature was decreased to 45°C and maintained for 12 hours. Thereafter, 0.2% of acetic acid was charged to neutralize the solution.
