  • Shaping: setting the shaping temperature at 190° C., which is higher than that of the ordinary fabric to make the fabric's shrinkage more adequately, and adding 1% hydrophilic softener, then putting the fabric into the shaping oven through the padder at the rate of 25 m/min of the padder.
  • Above all, in the dyeing and finishing method for linen cotton textile fabric with high-shrinkage provided by the present invention, using the flake caustic to open the fiber of the fabric can obtain the unique fabric style, with a high shrinkage of the fabric and a pellet feeling appeared on the cloth cover, thus achieving the linen cotton effect and much more like the woven fabric and a better novelty.
  • It should be noticed that above embodiments are only examples of the present invention, but not limitations of patent scope of this invention. All other modifications and variations made according to the description of the present invention, or applications used in other relevant technical fields directly or indirectly, should be considered as falling within the patent protection scope of this invention.
