Definitions

  • THIS INVENTION relates to impervious plastic materials formed to a sheet-like configuration and having on one major surface thereof a textile liner secured relative to the plastics material as a result of the latter extending partway through the thickness of the liner.
  • Impervious plastic materials having liners on one surface thereof are employed for many different purposes but are particularly useful in the protective clothing industry.
  • One noteworthy example of such impervious plastics materials is in their use as protective gloves in which case a prefabricated textile liner carries on the outer surface thereof an impervious layer of plastics material such as a polyvinyl chloride (PVC) layer.
  • PVC polyvinyl chloride
  • Such impervious plastic materials having a liner on one major face thereon are usually made by either dipping a prefabricated liner into a basically liquid plastics composition in order to coat them effectively followed by curing of the plastics composition generally by heat.
  • the liner can have a paste-like plastics composition spread thereover by means of a suitable spreading device which is again followed by curing of the plastic material.
  • an impervious plastics material having a liner on one major surface thereof wherein the plastics material extends partway into the thickness of the liner in order to bond two layers of material together, and wherein the liner has applied to one surface thereof a plastics composition which is subsequently cured to define the impervious plastics material, the method being characterised in that the plastics composition includes titanate couplers and inorganic fillers wherein the plastics materials, couplers and fillers are adapted to co-operate with each other to provide the required consistency of the composition during application of the plastic layer to the liner.
  • the plastic composition to be a PVC composition and, in particular, an emulsion polymer or plastisol; for the plastic composition to include any required plasticisers, heat stabilisers, pigments or the like; for the inorganic fillers to be present in amounts of between 10 and 50, preferably from 35 to 50, parts by weight per 100 parts of plastic material and for the titanate to be present in an mount of up to 2% based on the weight of filler employed.
  • Still further features of the invention provide for the above defined method to be applied to the manufacture of protective gloves in which case a glove ' liner is positioned on a former therefor and the plastic composition is applied to the outside of the liner located on the former.
  • the glove comprises a preformed liner 1 made of a textile material and which may be either fabricated to the required shape or knitted to . that shape by automatic machines which are available and known in the art.
  • the liner can be, if required, a single jersey type of material, an interlock material, or the automatic knitted liner mentioned already.
  • the advantage of employing a plastic composition according to this invention to define the impervious OVC layer 2 on the outer side of the liner is that the liner can be made to an appreciably lighter weight than heretofore. For example, in place of the conventional 230 to 250/m 2 density of the liner only approximately 150g/m 2 are necessary when the present invention is employed. This represents an appreciable saving in the cost of material from which the liners are made.
  • the plastic composition for coating the abovedescribed liner was, in this case, PVC plastisol material composed of a mixture of two different emulsion polymers of a dipping grade.
  • the two polymers in question were those sold under the name Pevikon 737 by KEMA-NORD AB of Sweden (24 parts by weight) and CORVIC P7250 sold by A.E.C.I. LTD. of South Africa (56 parts by weight).
  • the liner located on a former 3 was dipped into the plastic composition described above and then cured at a curing station 4 in the usual way whilst on the former.
  • protective gloves manufactured according to the abovedescribed process have substantially as good a chemical and physical properties as similar gloves made using standard weights of liners and substantially no inorganic fillers and, in fact, the flexibility is increased in some cases. This may result from the fact that a lower temperature can in fact be employed to cure the PVC material than in the prior art process.
  • the invention therefore provides a simple yet effective method of manufacturing flexible, impervious lined materials which results in less costly articles of equal properties to those manufactured by the prior art processes.
