Definitions

  • the filament yarns become drawn, i.e. irreversibly elongated, in the regions between their intersections to a greater extent than that at their crossover regions. This becomes apparent when the drawn fabric is dyed, since it then has dye flecks of darker colour at the crossover regions of the yarns. However these regions should be suiciently strong not to affect adversely the mechanical properties of the fabric.
  • a process for making a fabric having an open mesh construction comprises knitting or weaving a fabric fromv synthetic yarn capable of being irreversibly elongated at least 1.75 times its length, and drawing the knitted or woven fabric uniformly over substantially the whole area of the fabric at least 1.75 times in at least one direction. If desired, the fabric may also be drawn at least 1.75 times in another direction, preferably at right angles to the first draw- ⁇ ing direction.
  • Undrawn or partially drawn yarn may be used in the invention.
  • a birefringence in the range of 2 103 to 20X 10-3 preferably 12X 10-3 to 16 103 is suitable.
  • Such a yarn is capable of being elongated 2-6 times its length.
  • polypropylene yarn this should be capable of being elongated at least 1.75 and up to 9 times its length.
  • Suitable polypropylene yarns have a birefringence of l 10n3 to 30 103 and preferably between 10 103 and 20X 10-3.
  • the fabric may be drawn between pairs of rolls, rotating at suitable speeds to give the desired draw ratio in the fabric in the longitudinal direction.
  • the fabric may be gripped at the edges by clips which can be made to separate by a given amount corresponding to the desired draw ratio.
  • equipment used for biaxially orienting film may be used for drawing our fabric.
  • the fabrics are useful for industrial applications e.g.
  • One suitable form of apparatus comprises means forward drawing and sideways drawing the fabric w means for heat setting the ⁇ fabric on a stenter before is wound up.
  • the forward drawing means compri hot nip rollers which may be heated by hot water c to about 85 C. and cold nip rollers.
  • the draw point located between the two sets of nip rollers beneath infra red heater.
  • the draw ratio is determined by i relative speeds of the cold and hot nip rolls.
  • the f ⁇ ward drawn fabric is fed from the cold nip rolls intc sideways draw stenter where it is held by self-grippi clips with means for controlling the temperature for l ample between and 100 C.
  • stenter is a second and larger part where the fab is heat set and which is provided with means for movi the fabric and heating it to temperatures up to ab( 240 C. Means are provided for cooling the fabric forced air before it is wound up on a beam which driven from the fabric forwarding means on the sten ⁇ by an arrangement adapted to compensate for the bui up of fabric on the beam.
  • the fabric is preferably provided with selvedges to fac itate gripping for drawing in width.
  • FIG. l shows a sample warp-knitted from undra polyethylene terephthalate yarn
  • FIG. 2 shows a similar sample as shown in FIG. after drawing 3.5 times in length only
  • FIG. 3 shows a similar sample as shown in FIG. after drawing 3.5 times in width only
  • FIG. 4 shows a similar sample as shown in FIG. after drawing 3.5 -times in bot-h length and width.
  • the fabric has been knitted fr( 80 denier yarn on a 28 gauge high speed warp-knitti machine to 60 courses per inch, using a marquisette cc struction.
  • FIG.A 4 a fabric with a Wide open me is obtained after'drawing the fabric, as shown in FIG. to 3.5 times its length followed by drawing to 3.5 tim its width.
  • Such fabrics are sheer, light in weight a1 suitable for reinforcement in coated or laminated stru tures.
  • Example 1 Warp knitted reverse locknit fabric was knitted from denier undrawn polyester yarn of birefringence Useful fabrics were obtained, which on examination showed that:
