TEXTILE FABRIC RENDERED SOIL RESISTANT WITH ALUMINUM PHOSPHATE AND METHOD OF PRODUCING SAME Patrick A. Florio, Elmhurst, N. Y., assignor to Mohasco Industries, Inc., a corporation of New York No Drawing. Application April 13, 1954, Serial No. 422,987
12 Claims. (Cl. 117-169) This invention relates to the treatment of surfaces to reduce the adherence or attraction of particles thereto ahd more particularly to the treatment of fabrics, paper and paper-like materials, paint films and other materials to reduce their color change due to pick-up and retention of particles on their exposed surfaces.
A more specific object is to reduce color change or greying of fabrics (flat or pile), covering or wrapping material, such as paper, and films, such as paint or varnish, due to the pick-up and retention of particles during use.
Another object is to reduce the particle adherence of surfaces without introducing an undesirable discoloration or whitening or otherwise harmfully altering the appearance or feel of the treated material.
Another object is to reduce the adherence of soil particles to surfaces.
Other objects and advantages will be apparent as the nature of the invention is more fully disclosed.
The treatment in accordance with this invention comprises depositing on the surface to be protected a composition containing aluminum phosphate and having characteristics which make it effective for the purpose as illustrated by the specific examples.
The composition may be applied to the surface from a dispersion under conditions to leave a coating of the desired weight and composition after the vehicle has been removed.
The surface can be treated in various ways depending upon its type and the results desired. In the case of pile fabrics, such as rugs or carpets, a water dispersion of the compositon may be sprayed over the pile surface in an amount to produce the desired. particle pick-up, or the dispersion may be applied by means of a carpet cleaning brush and then dried, or the fabric may be inverted and the pile only dipped into the dispersion. When used as a part of a standard rug-making process the dispersion may be sprayed onto the pile (face up) or the pile dipped (face down) after sizing and the treated rug then passed through a standard drier'for removing the vehicle. If the treatment is applied to a carpet on the floor it may be dried. at room temperature'by, allowing it to stand for 'a sufficient period'of time;
After drying the coating has' the property of adhering strongly to the surface. sult of repeated cleaning or use it can be easily renewed.
The treatment is eifective on various textiles such as- Cotton pile rugs may be immersed in the dispersion until the desired pick-up has taken place on the fibers. The fabric is then passed between squeeze rollers and dried to leave the desired coating on the pile.
nited States Patent If eventually removed as a re 2,786,787 Patented Mar. 26, 19 57 The dispersion may be applied to wall paper or to a surface by spraying or painting technique and allowed to dry at room temperature to form a coating having the characteristics above described.
5 The treatment is suited in general for any surface which is subject to particle adherence.
In accordance with this invention a dispersion of aluminum phosphate (A1PO4), a water insoluble phosphate of extremely small particle size, in salt free water.
' Example 1 A dispersion made by mixing 1 part of aluminum-phos phate (AlPO4) of extremely small average particle size (70 millimicrons and below) in 99 parts of salt free water, was stirred vigorously for a period of 10 minutesv A pile fabric having 22 ounces per square yard of pile fiber was treated by immersion face down in this dispersion at room temperature to produce a solids pick-up of 1% on a dry basis on the pile Weight. This corresponds to a pick-up of 0.011 ounce per square yard of exposed fiber surface area.
' Example 2 A dispersion made by mixing 1 part of aluminum phosphate (AlPO4) of extremely small average particle size (70 millimicrons and below) and 0.25 part of trisodium phosphate (NasPO4-l2H2O) and 98.75 parts of salt free water was sprayed at room temperature as a line mist on to the pile surface of an Axminster pile carpet having a 40 backing composed of cotton chain and filler yarns, jute stuffer yarns and one-half inch pile having a weight of.
. 23.2 ounces per square yard composed of a blend of 50% wool and 50% rayon. The pH of the pile may be 4 to 6.5. The spray may be controlled so that the weight of the dispersion taken up by the pile is about 100% of the pile weight and is concentrated on the pile with the backing remaining substantially dry. The carpet is then passed through a drier at a temperature of about 175 F. to remove the water and leave a coating of aluminum phosphate on the pile of about 1% by weight of the pile,
corresponding to about .011 ounce per square yard of exposed fiber surface area. The coating is most concentrated at the free ends of the pile although some of the coating may extend down to the portion of the pile anchored in the backing. 6
Example 3 A dispersion made by mixing 1 part of aluminum phosphat (AlPO4) of extremely small average particle size (70 millimicrons and below), 0.25 part of trisodium '60 phosphate, N213PO4-12H2O), 0.25 part of Carbowax (a polyethylene glycol high molecular weight wax made by Carbide and Carbon Chemicals Corporation), and
98.75 parts .of salt free water, was applied to the exposed fiber surface of a pile fabric containing a blend of carpet wool and viscose rayon by spraying at room temperature. After drying, a pick-up of 1% aluminum phosphate on the pile or .011 ounce per square yard of exposed fiber surface was obtained.
Example 4 dispersion was made by mixing 0.5 part of aluminum phosphate, 0.25 part of trisodium phosphate, and 0.25
arrears? part of Oarbowax into 5916 parts of salt freewater. 'E'hg mixture was stirred vigorously for 10 minutes. This dispersion was used to treat carpet as above.
Example Other materials may beadded to the dispersion states; to improve the soil fepeuencyqimntiee lior exainplg a dispersion was made by mixing 0l5 par t of aluminum phosphate, 0.25 part of Ludo)? snicdfipnde' s old by Du Pont), 0.25 art or tris'odiu'rii pses iate, 0 25 ar: of CarboWax; and 98175 parts of salt nee water. mixture was stirred vigorously fora period or o, rninntes, The dispersion was used to treat carpet as in Examples 1 to 3. n
Other metal oxi es may be used" in precep Ludox, us such as Alon, an aluminum oxide soldb'y Go'dfrey Cabot, Inc'., aluminum aerog'el, titaniili'iioxide, etc. Representative Water dispersions of these materials are set forth in the following table:
