Definitions

  • the invention refers to fabric containing copper.
  • the fabric is manufactured with the known methods of weaving or knitting on weaving looms or knitting machines respectively.
  • the threads used for fabric manufacture contain copper wire.
  • the antimicrobial fabrics marketed for various uses are manufactured in ways using chemical or mechanical methods.
  • Chemical method is the coating of the fabric surface using binding nanotechnology to achieve antimicrobial properties. This method has the disadvantage of weakening up to dissapearing the antimicrobial properties when subjected to repeated cleaning processes, wet washing or dry cleaning.
  • Mechanical method is the embodiment of copper oxide particles in the fibre mass.
  • the copper oxide nano-particles are mixed with the lot of fibres to produce the yarn.
  • the mechanical elaboration of the fibre lot embraces the copper oxide particles during the carding and spinning process.
  • This method is also subjected to the disadvantage of weaker initial antimicrobial properties which eventually deteriorate after reitarated cleaning methods as the copper oxide particles are removed with repeated wet washing.
  • Threads using silver wire as core and any other yarn as cover are effective in antimicrobial properties but costly to produce.
  • the present invention differs as it incorporates solid copper wire, already available in the market, which is embeded in the thread in two ways. One way is by knitting the copper wire with the yarn into a chain stitch cord and not as an inlay, the other way is by twisting the yarn with the copper wire, both methods being industrially easy and establish a low cost production as the copper wire used does not need any extra preparation being available in the market for various uses.
  • Copper as mentioned in numerous scientific studies, has antimicrobial action.
  • the microbes die within one or two minutes when in contact with copper.
  • Scientific researches published in international medical magazines and forums for copper, strongly support the antimicrobial properties. It has been proven that by covering with copper the most frequently touched surfaces in hospitals and intensive care units, such as tables, side boards, stands, door handles, toilet seats, can minimise the cases of hospital infections, in comparison to patients threated in other hospitals.
  • a decrease in pestilential diseases affecting students has been observed also, when antimicrobial fabric was used as cutrains in schools.
  • the thread production for antimicrobial fabric is achieved in two ways.
  • One way is to use a circular knitting machine for chain stitch cord production, whose dial diameter and number of needles used determine the cord thickness, where the copper wire is interlocked with the yarn.
  • the other way is to use a twisting machine where the spindles twist the yarn with the copper wire.
  • the resulting thread, with the copper wire exposed on the thread surface, is then used to produce a woven or knitted fabric or article.
  • the choice of the material, of natural or synthetic origin, as well as the thickness determines the thread quality.
  • the fabrics produced with these threads can be used for protection against microbes. The uses vary from seat covers for car and transport industry, to bed sheets for hospitals, medical clothing, masks or gloves, socks and many other.
  • the level of twist, the thread thickness, the sysnthesis and density of the weave or knit determine the end use of the fabric.
  • the purity of the copper wire as well as the thickness is essential as it affects flexibility, drape, endurance, comfort, appearance, utilization and effectiveness.
