  • the garments are compose of non-woven, woven, knitted or otherwise formed film o fabric of thermoplastic polymer or fiber which are wate soluble at temperatures only above approximately normal huma body temperature (37°C) .
  • the Act calls for the establishment of an exposure control plan, the containment of specimens of blood or other potentially infectious materials and the general tightening of precautionary measures to minimize the spread of disease.
  • a safe and effective way to dispose of hospital waste in the form of soiled garments and apparel would greatly facilitate compliance with the above-referenced Act.
  • Disposable medical fabrics are generally currently composed of thermoplastic fibers such as polyethylene, polypropylene, polyesters, polyamides and acrylics. These fabrics can also include mixtures of thermoset fibers such as polyamides, polyarimids and cellulosics.
  • U.S. Patent No. 3,413,22 teaches the production of water soluble bags or pouches fro which packets or the like are produced containing suc materials as detergents, bleaches, insecticides, medicinals chemicals, dyes, pigments, industrial additives and othe materials. It is taught that the contents of the packets ar dispersed merely by dropping the packets into water whereupo the bags dissolve and release their contents into aqueou dispersions.
  • the referenced patent teaches th production of such films which are both hot and cold wate soluble.
  • U.S. Patent No 3,859,125 teach the production of layered articles whic include coatings of polyvinyl alcohol.
  • the subject referenc teaches coating polyvinyl alcohol on a paper membrane whereb it is taught that the coated paper is soluble in either hig or low temperature water. Again, it is incorrect to believ that a cellulose sheet material would be "soluble" in a aqueous solution. At best, cellulose merely disperses Similarly, U.S. Patent No.
  • 4,343,133 teaches the coating o polyvinyl alcohol onto a non-woven fiber sheet impregnate with latices of polyvinyl acetate in the manufacture of premoistened towelette which can be disposed of by flushin in plain water without danger of clogging a plumbing system
  • the present invention involves a method of disposing of garments after use which comprises providing the garments as sheets or as woven, non-woven, knitted or otherwise formed fabric of thermoplastic polymer or fiber.

  • Such fibers or sheet would be insoluble in cold to warm baths below 37°C, th average temperature of the human body.
  • the polyme or fabric would be soluble in baths only above 50°C, and, mos preferably the polymer or fabric garments would be solubl only in aqueous media between 80°C to 90°C.
  • Garments which are soluble in aqueous media belo 37°C are useless as inadvertent secretion of bodily fluid such as blood and urine would cause the polymer to solubilize.
  • Working with polymer which dissolves only at highe temperatures such as above 50°C or, ideally between 80°C an 90°C would prevent inadvertent solubilization yet remain ideal in practicing the present invention. It is contemplated that disposal in a hot water bath such as a washing machine at o near the boiling point of water dedicated solely t solubilizing garments, linens, drapes, towels and other useful articles produced herein would also be an effective disinfecting media.
