Definitions

• Our present invention relates to atreatment' of fabrics and other materials with metallic compounds designed to impart antimicrobial properties to 'such'materials.”
• the treatmehtdis' closed in these pending applications involves theinimersion of the material'in an'aqueous bath at hight'eni peratures, the bath includingas its principal ingredients a chelating agent, a catalyst'su-ch as sodium acetate an'd optionally a detergent along with'za suitable zincfcompound such as zinc chloride:
• a fixingagent rich in amine groups, such as urea is applied'to thernaterial' either" in the'sarne bath' or in a second treatment solution to help lock the zinc in place on the fibers.
• an object of our present invention to provide an improved process for supplying such compositions to fibrous materials at ordinary temperatures and without the use of a slow-drying aqueous medium; a related object is to provide a modified antimicrobial composition adapted to be so applied.
• a zinc salt a chelating agent, a catalyst, an aminating agent and preferably a detergent and buffering agent in an organic solvent, advantageously, a low-boiling ketone.
• an organic solvent advantageously, a low-boiling ketone.
• ketones found suitable for the process'of our invention, the lower-boiling ones being preferred because of their shorter drying time.
• Trifluoro acetone-" 21 Acet s 56 Hexafluoroacetyl acetone; 63-65 Z-bntanone (ethyl methyl) B buten Z-one (methyl vinyl) 81 Biacetyl acetone 88 Methyl isopropyl ketone; 94.3 Diethyl acetone 1 02 Methyl propyl ketone 102.3 Pinacolone H V 106 Methyl isobutyl ketone 116.8 Cyclohexanone' 156' The folowing proportions (by weight) have been found to give a satisfactory mixture:
• the zinc compound is preferably zinc chloride but may also be zinc sulphate or zinc nitrate.
• Detergent such as ethylene cycloimido l-alkyl (fatty acid) 2-hydroxy ethylene sodium alcoholate methylene sodium carboxylate 10 17.5 grams of the above mixture together with 17.5 grams of urea crystals are dissolved in 1000 grams of acetone. The resulting solution is sprayed at room temperature by means of an atomizer onto a piece of cotton or wool textile and allowed to dry for about two minutes.
• a sample of the textile so treated is washed 20 times in a household washing machine with soap or detergent and is then placed on a Petri dish containing agar streaked with a culture of Staphyl coccus aureus. After an incubation period of 24 hours a 2-mm. zone of inhibition is observed.
• the zone of inhibition is found to be 3 mm.
• Example 2 The same as Example 1, except that cyclohexanone is used as a solvent in place of acetone. The solution dries in about five minutes.
• a l-mm. zone of inhibition against Staphylococcus aureus is observed after 20 washings.
• Example 3 Methyl isobutyl ketone is used as a solvent in lieu of those given in Examples 1 and 2. The drying time is about three minutes. The same zone of inhibition is observed as in Example 2.
• the concentration of the mixture of the aforedescribed solids in the organic solvent may vary from 0.1% to the saturation point, the latter being approximately 5%.
• composition according to the invention can also be used successfully on synthetic fibers, such as nylon.
• alkali-metal acetates such as potassium or 1ithium acetate, may be used as the catalyst in lieu of sodium acetate.
• An antimicrobial treating composition comprising a zinc salt, an aminating agent and a chelating agent all distributed in a volatile organic solvent.
• a composition according to claim 2 including as a catalyst an alkali-metal acetate.
• composition according to claim 3 including a detergent.
• composition according to claim 3 including a buffering agent.
• textile fiber impregnated with a composition comprising a zinc salt, an aminating agent and a chelating agent all distributed in a volatile organic solvent.
• textile fiber is selected from the group consisting of cellulosic, proteinaceous and nylon fibers.
• An antimicrobial treating composition comprising a zinc salt selected from the group consisting of zinc chloride, zinc sulfate and zinc nitrate; urea; sodium ethylenediamine-tetraacetate and a volatile organic solvent.
• a process for imparting antimicrobial properties to textile fibers comprising applying to said fibers a solution of a zinc salt, an aminating agent and a chelating agent dissolved in a volatile organic solvent and allowing said solution to dry whereby antimicrobial properties are imparted to said textile fibers.
• a process for imparting antimicrobial properties to textile fibers comprising applying to said fiber a solution of a Zinc salt, a chelating agent dissolved in a volatile organic solvent, treating the fiber with an aminating agent and allowing said fiber to dry whereby antimicrobial prop erties are imparted to said textile fiber.
