Description

United States Patent PROCESS OF PRODUCING METALLIZING EFFECTS ON TEXTILES Albert Bodmer and Karl Risch, Wattwil, Switzerland, as-
signors to Heberlein Patent Corporation, New York, N.Y., a corporation of New York No Drawing. Application March 22, 1955 Serial No. 496,064
Claims priority, application Germany March 23, 1954 13 Claims. (Cl. 117-71) This invention relates to a process of metallizing textiles and to the resulting products.
The process of providing various textiles with a thin metal coating by depositing thereon vaporized metals in a high vacuum, thereby imparting to these textiles a metallic appearance without impairing the valuable textile properties such as flexibility, suppleness, and heat retention, is known, Nevertheless, in the case of textiles consisting of natural or artificial cellulosic material metal coatings so deposited tend to crock or peel off from the fiber or fabric particularly when such fabric or fiber is wetted.
The principal object of the present invention, accordingly, is to eliminate this difiiculty, at least in .part.
The invention comprises the novel products as well as thenovel processes and steps of processes according to which such products are manufactured, the specific embodiments of which are described hereinafter by way of example and in accordance with Which we. now prefer to practice the invention. p
In accordance with our invention, we have found that crocking or peeling of such metal-coated textiles is due at least in part to swelling of the cellulosic fiber on wetting same. The swelling increases the dimensions of the fiber and since the metal does not similarly swell, it is loosened and comes off. Another reason for such crocking or peeling is that cellulosic fibers, in themselves, have a low adhesion to metals so deposited as compared with natural animal fibers or completely synthetic polymer fibers. The expression cellulosic textile, or fabric, as used herein, is intended to designate a textile fabric composed of, or containing substantial amounts of artificial cellulosic fibers such as viscose or similar regenerated cellulose or natural cellulosic fibers, such as cotton and other cellulose containing natural fibers.
We have also found, in accordance with our invention,
that the defects mentioned may be at least in part overcome by treating the cellulosic textile or fabric with an antiswelling agent or agent to inhibit swelling thereof when coated with metal. Thereafter, such treatment appears to inhibit separation of the metal and to improve its adherence to the cellulosic material. A further improvement may be effected by thinly coating said material, in addition to the treatment with the anti-swelling agent, with a water-insoluble resin. When cellulosic material is so treated with both anti-swelling agent and a thin coating of resin, there is a great improvement in both the resistance to peeling or crocking. The resulting metallized products are accordingly resistant to the crocking and peeling mentioned.
Agents to inhibit the swelling of the cellulosic fiber include solutions of formaldehyde. Glyoxal and pyruvicaldehyde may also be used. These substances are employed with an acid catalyst. The so-treated textile is heated to an elevated temperature. Instead of such treatment, methylolamide resins and resins of acetone-formaldehyde may be incorporated in the textile.
For thinly coating the textile treated with the anti- 2,907,678 Patented Oct. 6, 1959 2 swelling agent, we may employ water-insoluble natural resins, such as shellac or rosin. As water-insoluble plastics, there are suitable for instance film-forming resins obtained by polymerization, particularly vinyl resins, for instance polymers of vinylchloride, vinylidenechloride, vinylacetate, vinylacetal, vinylbutyral or copolymers thereof, as Well as acrylic and methacrylic resins and also polystyrene resins. There can also be used filmforming resins obtained by polycondensation, particularly aminoplast-ether resins, for instance ureaor melamineformaldehyde-ether resins, alkyd resins, for instance glyptal resin, alkyd-alkylaminoplastether co-resins or ethoxyline resins. Resins or plastics can be applied to the textile material either in the form of solutions in organic solvents or in the form of aqueous emulsions. When resins are used which have the property ofcondensing further at higher temperature and thereby becoming insoluble such as, for instance, urea and mela:
treatment with the agent for reducing the swellability be calendered before the heating, which heating is part of the process for reducing the swellability, in accordance with our invention, for instance by means of a friction calender.
The following are examples of processes, in accordance with our invention, as we now prefer to practice it:
Example 1 Dyed satin which consists in the Warp and filling of viscose rayon is impregnated with an aqueous solution containing per liter cc. of 37% formaldehyde solution and 10 grams of oxalic acid. The treated fabric is dried on a tenter frame, heated for two minutes at C., rinsed with hot water, and dried on a tenter frame. The satin is then coated with aluminum by vaporizing the same at a temperature between 800-1000" C., in a high vacuum of about 510- mm. Hg, and condensing the aluminum on the satin to form a coating in a known manner.
Example 2 Example 3 Mercerized cotton poplin is impregnated with an aqueous solution containing per liter 50 grams dimethylol urea, 100 cc. of a 37% formaldehyde solution and 3 grams monoammoniumphosphate, dried on a tenter frame, heated for 2 /2 minutes at 140 C., to condense the dimethylol urea washed with water containing 2 grams soda per liter at 40 C., rinsed, dried, and thereupon treated in a high vacuum of about 5.10- mm. mercury, first of all with copper vapor at a temperature between 1000-1300 C. with subsequent deposition and thereupon with gold vapor at a temperature between:
I 1000-1500" C., with subsequent deposition.
Example 4 Dyed cotton percale is impregnated with an aqueous solution containing per liter 120 grams of tetramethylolmelamine and 5 grams of triethanolaminelactate as catalyst, dried on a tenter frame, friction-calendered wlth heated rollers, cured at 160 C. for 3 minutes, to further condense the tetramethylolamine, washed with water containing 2 grams dodecyl sulfate per liter, dried on a tenter frame and coated with aluminum by vaporizing and condensing same as in Example 1.
Example 5 Dyed spun-rayon cretonne is impregnated with a solution containing, per liter, 100 grams of tetrarnethylolmelamine and a catalyst, namely triethanolamine glycolate, which gives off acid in the hot, dried on a tenter frame, friction-calendered at about 160 C., heated at 160 C. for 4 to 5 minutes in a heating chamber, washed with a synthetic detergent such as sodium salt of taurine oleate, dried on a tenter frame, impregnated with an aqueous emulsion of polyvinylbutyral, containing 4% of said polyvinylbutyral, and dried on a tenter frame. Aluminum is deposited on the so-treated fabric in the manner given in Example 1.
Example 6 Dyed viscose taffeta is impregnated with an aqueous solution containing, per liter, 40 grams pure formaldehyde and grams of oxalic acid, dried on a tenter frame, heated. at 140 C. for 2 minutes, rinsed with hot water, dried on a tenter frame, impregnated with an aqueous 5% emulsion of a polymethacrylate, and dried on a tenter frame. Aluminum is deposited on the sotreated fabric in the manner given in Example 1.
Example 7 Dyed crepe lavable of cuprammonium rayon is impregnated with an aqueous solution containing, per liter, 90 grams of dimethylolethylene urea and 1.5 grams ammonium chloride, dried on a tenter frame, heated at 145 C. for 2 /2 minutes, rinsed with hot water, dried on a tenter frame, impregnated with an aqueous polyvinylacetate resin. emulsion containing 3% resin, and dried on a tenter frame. Aluminum is deposited on the so-treated fabric in the manner given in Example 1.
Example 8 Dyed crepe satin of viscose rayon is impregnated with a solution containing, per liter, 120 cc. glyoxal and 12 grams oxalic acid, dried on a tenter frame, heated at 145 C. for 3 minutes, washed with hot water containing 2 grams soda and 2 grams of a sodium salt of taurine oleate per liter, rinsed, dried on a tenter frame, sprinkled with a solution of a precondensate of methylolmelamine ether resin in toluene containing 8% of resin, dried, and finally heated at 140 C., for 4 minutes in order to cure the methylol-melamine resin. Aluminum is deposited on the so-treated fabric in the manner given in Example 1.
Example 9 Dyed cotton percale is impregnated with an aqueous solution containing per liter 100 grams tetramethylolmelamine and 4 grams triethanolamine glycolate. T hereupon the fabric is dried on a tenter frame, frictioncalendered with heated rollers, cured at 150 C. for
4 minutes, washed with water containing 1 gram soda per'liter at 60 C. and dried on a tenter frame. The fabric is then impregnated with an aqueous emulsion of a polymethacrylate containing grams solids per liter, dried on a tenter frame and coated with aluminum by vaporizing and condensing the same in the manner given in Example 1'.
Each of the fabrics prepared in accordance with the above examples shows a greatly improved resistance to cro'cking and when the materials are wet they show substantially no loss of metal coating the fibers. Thus, when materials of this sort are made up into wearing apparel, they show substantially no signs of crocking, even when the garments are'worn over long periods and show substantially no loss of coating even when wet.
