Definitions

  • the present invention relates to a bielastic fabric comprising biopolyamide yarn and elastane yarn, having excellent elastic properties and high dimensional stability, as well as to a cost-effective, efficient process for obtaining it.
  • the present invention relates to a process for obtaining such a bielastic fabric.
  • the present invention relates to a clothing or furniture item, at least partially made of such a bielastic fabric.
  • FIG. 1 shows the pattern of jersey fabric (weave of stocking stitch) seen from the knit side on the left and from the purl side on the right;
  • FIG. 3 shows the pattern of interlock fabric in which the front overlap of the front and back stitches is shown: the latter are represented by thinner lines solely to help understanding the figure itself, actually being all of the same length and width;
  • Figure 4 shows the pattern of the same interlock fabric in Figure 1 in which the overlap of the front and back stitches is shown in perspective;
  • the invention thus relates to a bielastic fabric comprising biopolyamide yarn and elastane yarn.
  • the term “bielastic” means that the fabric is elastic in the warp and weft directions.
  • biopolyamide means a polyamide entirely or partly of plant origin.
  • the biomass from which the biopolyamide for the purposes of the present invention originates is the castor seed, referred to as Ricinus communis".
  • the monomers used in the polymerization process are partly or totally derived from castor oil.
  • Biopolyamides exhibit high resistance to chemical agents, in particular to hydrocarbons, dimensional stability, relatively low density and good processability.
  • said biopolyamide is biopolyamide 6, biopolyamide 6.6, biopolyamide 6.10, biopolyamide 6.12, biopolyamide 11, biopolyamide 12, or a mixture thereof.
  • said biopolyamide is biopolyamide 6.6.
  • the biopolyamide yarn has a count of 10-200 dTex, preferably 20-150 dTex.
  • elastane it is meant a synthetic fiber of polyurethane, also known as Spandex or Lycra.
  • polyurethane is typically produced from raw materials.

  • the polyol is characterized in that it has hydroxyl functional groups (-OH) at both ends and will form the elastic part of the molecule; it may be a polyester or a polyether or a mixture thereof.
  • the diisocyanate instead, has isocyanate functional groups (-NCO) at its ends and will be the rigid part of the polyurethane.
  • the isocyanate most used is diphenylmethane diisocyanate ("MDI", l-isocyanate-4-[(4- phenylisocyanate)methyl]benzene).

  • the chain extension is obtained by adding bifunctional amines (H2NR-NH2) to the prepolymer, which by reacting with the -NCO groups form a urethane bond.
