Definitions

  • This invention concerns protective clothing, especially gloves, of the type (hereinafter called the type described) comprising fabric coated with a durable material. Usually such durable material is based on synthetic resin.
  • Protective clothing ⁇ of the type described is widely used both industrially and domestically, and a large percentage of such clothing is made from a knitted cotton fabric coated with suitably plasticized and stabilized polyvinyl chloride polymer, the latter being heat treated so as to gel or cure and provide the fabric with an extremely hard wearing lreinforcement which is also resistant to many agents which will cause traditional materials to deteriorate rapidly.
  • lt is such clothing, and especially gloves made by a dipping process, with which the present invention is particularly, though by no means exclusively, concerned.
  • penetration we mean (throughout the specification and claims) penetration right through onto the other surface of the fabric.
  • penetration we mean (throughout the specification and claims) penetration right through onto the other surface of the fabric.
  • special measures need to be taken if high quality clothing is to be produced, for example, as described and claimed in British Patent No. 624,795 to G. K. White.
  • the paste-that is, the suitably plasticized and stabilized polymer-does not penetrate the fabric before heat treatment and ilowing of the paste through the fabric in the early stages of the heat treatment part of the process is prevented by the sudden application of a high temperature.
  • the fabric construction and the rheological properties of the paste lmust be controlled.
  • the paste must have such viscosity and other properties Ias to prevent penetration.
  • the necessary viscosity and other properties of the paste limit ⁇ draining of the paste from the fabric after application and the thickness of the coating of paste cannot be substantially reduced beyond a certain minimum in any given case by prolonged draining
  • a thin coating is desirable.
  • the main object of the present invention is to provide a process whereby clothing of the type described may have 'a very thin coating, with no penetration.
  • a method of manufacturing clothing of the type described comprises the steps of applying on one side of the ⁇ fabric a coating of a substance which can be subsequently converted by gelling, curing or the like into a durable solid material, the nature of said substance and the manner in which it is applied to the fabric being such that there is no penetration; thereafter one or more times applying to the coating of the first substance 4on the fabric a further substance of such composition and in such a manner that it modifies the composition and the rheological properties of at least the outer layers of said lcoating so that more of the rst substance can be drained off the fabric than would have been possible by continued draining, before the application of said further substance; thereafter draining by the desired amount, and thereafter converting the coating as aforesaid and in such manner that there is no penetration.
  • Preferably application of at least one of the substances ⁇ is effected by dipping the fabric which is preshaped yand supported by la former and draining of the coating substance or substances by gravity or otherwise is allowed
  • the single FlGURE is a diagrammatical representation of the nature of the present process.
  • Another glove was produced in identical fashion except that the mix used for the second dipping (mix C) consisted of mix B with 85 parts by weight of Geon 202 polymer (a polyvinyl chloride polymer of a large granular size) added thereto.
  • the resultant glove had similar properties to the glove produced by using mix B.
  • mix D silica sand has been substituted for Geon 202 polymer produced similar results, save that the surface was rougher.
  • the number of additional dips may of course be more than one, and the dips may be in different mixes.
  • Glove l Mix A (one dipl, drained for forty minutes) 70.0 Glove 2: Mix A (two dips, drained each time for twenty minutes) 75.5 Glove 3: Mix A, then Mix B (drained twenty minutes after each dip) 54 Glove 4: Mix A, then Mix C (drained twenty minutes after each dip) 60.7 Glove 5: Mix A, then Mix D (drained twenty minutes after each dip) 57.0 Glove 6: Mix A, then Mix E (drained twenty minutes ⁇ after each dip) 56.3 Glove 7: Mix A, then Mix F (drained twenty twenty minutes after each dip) 57.0
  • mix A consisting of polyvinyl acetate emulsion 10() parts by weight and glycerine l0 parts by weight
  • mix B consisting of hot water
  • Glove 1 was dipped once in mix A, drained for twenty minutes, cured, and cut to standard size.
  • Glove 2 was dipped in mix A, drained for l0 minutes, dipping in Mix A again, drained for l0 minutes, cured, and cut to standard size.
  • Glove 3 was dipped in mix A, drained for ten minutes, dipped in mix B for ten minutes, drained for ten minutes, cured, and cut to standard size.
  • the weights of the finished gloves were as follows:
  • mix A consisting of polyvinyl alcohol 10() ⁇ parts by weight, water 400 parts by weight, and glycerine 25 parts by weight
  • mix B consisting of hot water
  • Glove l was dipped once in mix A, drained for ten minutes, and cut to standard size.
  • Glove 2 was dipped in mix A, drained for five minutes, dipped in mix A again., drained for tive minutes, cured, and cut to standard size.
  • Glove 3 was dipped in mix A, drained for ve minutes, dipped in mix B for five minutes, drained for ve minutes, cured, and cut to standard size.
  • the weights of the finished gloves were as follows:
  • a method of making a relatively thin impervious coating of a synthetic resinous material on the surface only of a fabric article of clothing without penetration of said material through said fabric which comprises (l) dipping said article into a first uncured composition taken from the class consisting of polyvinyl chloride paste, polyvinyl acetate latex, and polyvinyl alcohol latex, the viscosity of said composition being such as to prevent penetration thereof through the fabric and forming a relatively thick coating on said article;
  • a method according to claim 1 characterized in that said resinous material is polyvinyl acetate and said plasticizer is hot water.
  • a method according to claim l characterized in that said resinous material is polyvinyl alcohol and said plasticizer is water and glycerine.
