  • the nonshrinkable acrylic fibers positioned on the outside of the yarn should have a frictional characteristic similar to that of animal hair fibers. In this sense, the amount of the silicone resin deposited on the nonshrinkable acrylic fibers, or the monofilament fineness of said fibers, has a very critical significance.

  • the stress reduction rate tan a at the time of the kinetic friction means the gradient of the stress reducing part in which a slip occurs between the sample fabrics in the magnified measurement graph and can be indicated as a stress reduction rate per mm. of the displacement of the sample fabric. Therefore, it is apparent that the smaller the value of tan or shown in FIG. 2, the larger the slippery touch.

Then the sample fabrics are taken out and spread on a table without being dehydrated and are naturally dried. Then the diameters in the longitudinal direction and lateral direction of the circle described in each sample fabric are measured to determine the average values of the shrinkages in the longitudinal direction and lateral direction.

  • EXAMPLE 1 A spinning solution, obtained by dissolving in an aqueous solution of sodium thiocyanate an acrylonitrile copolymer obtained by copolymerizing 9.8 methyl acrylate and 0.2 sodium methallylsulfonate with 90 acrylonitrile, was wet-spun into cold water and was then water-washed and stretched in an ordinary manner to prepare a swollen gel fiber tow of a water content of 80 7a.

  • An acrylonitrile copolymer having the same composition as of the above mentioned nonshrinkable acrylic fibers was wet-spun in an ordinary manner.
  • the obtained acrylic fiber tow of a monofilament fineness of 3 deniers was fed into a turbostapler, was secondarily stretched to 1.16 times as long at a hot plate temperature of 150C, was then mechanically crimped and was cut to make highly shrinkable acrylic fiber staples having a latent hot water shrinkage of 12.8 (acrylic fibers 2).
  • the obtained mix-spun yarn was dipped in a mixed dyeing solution of a cationic dye and acid dye and was skein-dyed in one stage in one bath in an ordinary manner so that, at the same time, the latent shrinkability might be developed and a bulkiness might be imparted.
  • Two of such mix-spun yarns were plyed and were fed into a weft knitting machine of 14 G, were knitted into a plain knit fabric, were then stretched by 4 7a in the longitudinal direction and were set by Hoffman-set (knit fabric 1).
