Further, in order to obtain knitted fabrics, filaments and staple fibers (spun yarn) thereof are used. There are used filaments having a size of 11 dt (decitex: hereinafter, the same symbol is used) to 400 dt and staple fibers having a size of 160 S (cotton yarn number: hereinafter the same symbol) to 10 S.

  • These fibers may have any sectional shape, and may be modified cross-section fibers having a round section, a W-type section, or the like.
  • the rate of dimensional change upon water absorption is determined by the following methods. In the environment of 20°C and 65% RH, a fiber is measured for the fiber length (A) under a load of 0.05 g/dt (decitex), and then the fiber is dipped in water for 30 seconds. Subsequently, the fiber is taken out of the water and measured for the fiber length (B) after 30 seconds under a load of 0.05 g/dt.

  • fibers in a fabric are measured for the rate of dimensional change upon water absorption on the same conditions as described above by extracting the fibers from the fabric.
  • the fiber length to be measured is 30 cm, but when a fiber having a length of 30 cm cannot be extracted from the fabric, a fiber having a length as it is extracted is used for measurement.

  • Cellulose fibers may be converted to self-extensible yarns upon water absorption by treating conventional cellulose fibers in an aqueous alkali solution.
  • Alkali treatment of cellulose fibers is conventionally known. For example, mercerization is the most common treatment process.
  • cellulose fibers which extend by 3% or more upon water absorption have been successfully produced by subjecting cellulose fibers to severe alkali treatment contrary to conventional common sense.
  • cellulose fibers are obtained by dipping cellulose fibers, for example, in an aqueous solution containing sodium hydroxide in an amount of 20 g/L (liter) or more at 20°C or higher for 5 minutes or more.
  • Control of the extensibility upon water absorption is possible by controlling these conditions. For example, the rate of elongation upon water absorption will be lower as treatment conditions such as alkali concentration, temperature, and time are milder.

In this knitting, two-heater false-twisted yarns of polyester fibers with 167 dt/f were used as common fibers, and cuprammonium rayon fibers with 84 dt/45 f were used as cellulose fibers. In this case, the cuprammonium rayon fibers used are conventional cuprammonium rayon fibers which are not treated with alkali.
  • the knitted gray fabric was fed into a jet dyeing machine and scoured at 80°C for 20 minutes, and water was drained from the machine. Then, the scoured fabric was subjected to alkali treatment at a concentration of sodium hydroxide of 50 g/L at 30°C for 20 minutes. Subsequently, only the polyester fibers were dyed at 130°C. Since the dyed knitted fabric had unevenness, it was dried using a short loop dryer and then subjected to finishing set with a pin stenter at 170°C for 60 seconds by extending it to such an extent that wrinkles of the knitted fabric can be eliminated. Note that during the dyeing a water-absorbing agent was added to the jet dyeing machine. The resulting knitted fabric had a structure in which welt loops were successively formed in the course direction.
  • cuprammonium rayon fiber of the resulting knitted fabric was extracted and measured for the extensibility upon water absorption. It was found to be +5.7%.
  • the resulting knitted fabric was used to sew T-shirts to perform the wear test.
  • the results of the wear test are shown in Table 2.
  • the blending ratio of the cellulose fibers was changed by changing the size of polyester texturized yarns or the yarn arrangement during knitting, and the consecutive number of welt loops was also changed, from those employed in Example 13. Then, knitted fabrics were made on an experimental basis. The wearing comfort of the resulting knitted fabrics was evaluated, and the results are shown in Table 2.
  • Textures shown in Figure 13 were knitted with a 22-gauge double tubular knitting machine so that common fibers were arranged in texture 1 and composite yarns containing cellulose fibers were arranged in textures 2 and 3. Textures 1 to 2 were repeatedly knitted four times, and then textures 1 and 3 were repeatedly knitted four times. Such knitting was repeated to form a knitted fabric.
  • the polyester fibers were dyed at 130°C. Since the dyed knitted fabric had unevenness, it was dried using a short loop dryer and then subjected to finishing set with a pin stenter at 170°C for 60 seconds by extending it to such an extent that wrinkles of the knitted fabric can be eliminated. Note that during the dyeing a water-absorbing agent was added to the jet dyeing machine. The resulting knitted fabric had a structure in which tuck loops were successively formed in the course direction.
  • cuprammonium rayon fiber of the resulting knitted fabric was extracted and measured for the extensibility upon water absorption. It was found to be +5.7%.
  • the resulting knitted fabric was used to sew T-shirts to perform the wear test.
  • the results of the wear test are shown in Table 2.
  • cuprammonium rayon fibers with 56 dt/30 f were arranged in the front as common fibers; cuprammonium rayon fibers with 56 dt/30 f were arranged in the back as cellulose fibers; and the texture was knitted with the "all-in threading" in which the yarns are threaded through all needles.
  • the cuprammonium rayon fibers used are conventional cuprammonium rayon fibers which are not treated with alkali.
  • the knitted gray fabric was fed into a jet dyeing machine and scoured at 80°C for 20 minutes, and water was drained from the machine. Then, the scoured fabric was subjected to alkali treatment at a concentration of sodium hydroxide of 50 g/L at 30°C for 20 minutes. Subsequently, the polyester fibers and the cuprammonium rayon fibers were dyed. Since the dyed knitted fabric had unevenness, it was dried using a short loop dryer and then subjected to finishing set with a pin stenter at 170°C for 60 seconds by extending it to such an extent that wrinkles of the knitted fabric can be eliminated. Note that, during the jet dyeing, a water-absorbing agent was added to the jet dyeing machine.
  • the resulting warp knitted fabric was measured for the reduction rate of knitted fabric density. It was found to be 17.8%.
  • the cuprammonium rayon fiber of the resulting knitted fabric was extracted and measured for the extensibility upon water absorption. It was found to be +5.8%.
  • a warp knitted fabric was produced by changing the texture in Example 19 in which the amount of the swing of cellulose fibers, the blending ratio, and looping were changed. The wearing comfort of the resulting knitted fabric was evaluated. The results are shown in Table 3.
  • the following Examples 23 to 34 are made from yarn self-shrinkable upon water absorption and thus outside the scope of the present invention.
  • Textures shown in Figure 14 were knitted with a 28-gauge tubular knitting machine. Two-heater false-twisted yarns of polyester fibers with 84 dt/36 f were used for texture 1 as common fibers, and cuprammonium rayon fibers with 84 dt/45 f having a twist coefficient of 18,000 were used for texture 2. Textures 1 to 2 were repeatedly ten times, and then texture R in non-separated portions (as shown in Figure 9 ) was knitted so that a finished width of 4 mm is obtained using two-heater false-twisted yarns of polyester fibers with 56 dt/24 f which are non-shrinkable yarns.
  • the knitted gray fabric was fed into a jet dyeing machine and scoured at 80°C for 20 minutes. Subsequently, only the polyester fibers were dyed at 130°C. Since the dyed knitted fabric had unevenness due to the presence of the above-described widths, it was subjected to tentering set with a pin stenter at 170°C for 60 seconds by extending it to such an extent that the projections are extended.
  • the resulting knitted fabric was used to sew T-shirts, which were subjected to the wear comfort test during perspiration by physical exercise.
  • Warp knitted fabrics were produced by using cellulose fibers in which the twist coefficient is changed as shown in Table 4 or by changing the width of non-separated portions, from those in Example 23, and the resulting knitted fabrics were evaluated.
  • Textures shown in Figure 15 were knitted with a 28-gauge tubular knitting machine. Two-heater false-twisted yarns of polyester fibers with 84 dt/36 f were used for texture 1 as common fibers. The yarns were used as the main portion of a plain knitting texture and partially connected to the cylinder side with a tuck texture. Plated stitch of two-heater false-twisted yarns of polyester fibers with 56 dt/24 f as common fibers and cuprammonium rayon fibers with 84 dt/45 f having a twist coefficient of 18,000 was used for texture 2.
  • Textures 1 to 2 were repeatedly ten times, and then texture R of non-separated portions (as shown in Figure 9 ) was knitted so that a finished width of 5 mm is obtained in a circular rib texture using two-heater false-twisted yarns of polyester fibers with 56 dt/24 f as common fibers.
  • the knitted gray fabric was fed into a jet dyeing machine and scoured at 80°C for 20 minutes. Subsequently, only the polyester fibers were dyed at 130°C. Since the dyed knitted fabric had unevenness due to the presence of the above-described widths, it was subjected to tentering set with a pin stenter at 170°C for 60 seconds by extending it to such an extent that the unevenness is extended.
  • the resulting knitted fabric was used to sew T-shirts, which were subjected to the wear comfort test during perspiration by physical exercise.
  • Textures shown in Figure 16 were knitted with a 28-gauge tubular knitting machine. Two-heater false-twisted yarns of polyester fibers with 84 dt/36 f were used for textures [1], [2], [4], [5], [6], and [8] as common fibers. Cuprammonium rayon fibers with 56 dt/30 f having a twist coefficient of 25,000 and two-heater false-twisted yarns of polyester fibers with 56 dt/24 f as common fibers were used for textures [3] and [7]. These were adjusted with plated stitch so that the knitted fabric surface is formed from polyester fibers with 56 dt/24 f.
  • the knitted gray fabric was fed into a jet dyeing machine and scoured at 80°C for 20 minutes. Subsequently, only the polyester fibers were dyed at 130°C. Further, a water-absorbing processing agent was added during the dyeing to proceed dyeing while imparting water absorbability to the knitted fabric. Since the dyed knitted fabric had unevenness due to the presence of the widths, it was dried with a short loop dryer and then set with a pin stenter at 170°C for 60 seconds while tentering it by 10% of the width of the dried fabric.
  • the resulting knitted fabric was a three-dimensional tubular knitted fabric in which projections were developed in the outer layer portions (C) knitted in the cylinder side, and the thickness of the projections were reduced by sweat absorption.
  • Three-dimensional tubular knitted fabrics were produced by changing the ratio of the number of courses of both outer layers, (C)/(D), by changing the number of knitting in [3], [4], [7], and [8] from those in Example 29, and these fabrics were evaluated. The results are shown in Table 5.
  • Sample Cellulose fibers Alkali concentration (g/L) Treatment temperature (°C) Treatment time (min) Extensibility upon water absorption (%) Wearing comfort
  • Cuprammonium rayon 80 30 20 6.7 4 Ex. 5 Cuprammonium rayon 60 20 20 5.6 4 Ex.
