Definitions

  • the present invention relates to an apparatus for continuously reducing the weight of knitted and woven fabrics of polyester fibers.
  • This is effected by applying, by for example a padder, to the fabric or textile material an aqueous solution of 70 to 90% by weight based on the weight of the textile material and containing D.5 to 2.5% by weight of sodium hydroxide, subjecting the padded textile material to steam, using for example a J-box steam chamber, while maintaining the moisture content thereof to at least 35% by weight of the weight of the textile material so as to remove 0.4 to 2.5% by weight of the polyester, and thereafter washing the textile material, using for example a three-zone washer, to remove unreacted sodium hydroxide.
  • apparatus for continuously reducing with alkali the weight of fabric made of polyester fibers, comprising, in series a padder for uniformly applying an alkali solution, that serves as a hydrolyzing agent, to the fabric; a steamer chamber, operating at a temperature of 100°C to 125°C, for promoting the hydrolysis of fabric impregnated with the alkali solution, said steamer chamber being provided with a ceiling and, in an upper portion of the chamber, with indirect steamer pipes for preventing condensation on the ceiling of said steamer chamber, and also being provided with direct steamer pipes for controlling the temperature of said steamer chamber; means for washing the fabric with water in order to remove hydrolyzed products from the fabric, said washing means comprising a plurality of superimposed stages of which at least one comprises a vessel containing water, feed rolls in said vessel for transporting the fabric, squeezing guide bars over which the fabric runs, and holder rolls cooperating with said feed rolls to squeeze the fabric; and a device for drying the fabric.
  • Fig. 1 is a plan view schematically illustrating the apparatus according to an embodiment of the present invention
  • Fig. 2 is a side view showing the apparatus of Fig. 1.
  • reference numeral 1 denotes a vessel, containing an alkali solution, into which fabrics are dipped
  • 2 denotes nip rolls made of a rubber.
  • the fabric to be treated is immersed in the alkali solution in the vessel 1, and is nipped through the rolls 2 so that it is impregnated with the alkali solution at a desired pick-up.
  • a steamer chamber 3 accommodates indirect steamer pipes 4 for preventing the formation of dew on the ceiling, direct steamer pipes 5 for adjusting the temperature, and large and small feed rolls 6 for conveying the fabric when it is spread out.
  • the temperature can be suitably adjusted over a range of 100°C to 125°C.
  • the fabric which is hydrolyzed as it goes through the steamer chamber 3 and the weight of which is reduced with alkali, is then introduced into a vessel 7 containing water for washing the fabric, wherein the hydrolyzed products contained in the fabric are removed in a plurality of stages by washing the fabric with water.
  • Feed rolls 8 and squeezing guide bars 9 are provided in the vessel 7, and holder rollers 10 are disposed on the feed rolls 8 to squeeze the fabric by nipping.
  • the fabric, coming from the vessel 7, is then dried as it goes through an ordinary drying machine 11 made up of cylinders.
