Description of the Related Art Polyamide fibers have been used in various fields such as not only for clothing but also for industrial and interior purposes due to their excellent properties. Particularly, in the field of legwear such as pantyhose and tights, and innerwear such as lingerie and foundation, polyamide fibers have been widely used because of their strength and flexibility. However, these polyamide fibers have a unique slimy feeling and are less dry and dry compared to natural fibers such as silk and hemp, causing a stuffiness and stickiness when directly touching the skin. In terms of time comfort was inadequate. Further, the appearance was only a uniform plain tone unique to synthetic fiber, and lacked a natural feeling such as a span tone.

The knitted fabric may be knitted with synthetic fibers such as polyethylene terephthalate and polyacryl or elastic fibers such as polyurethane. The knitting method may be warp knitting or weft knitting, and examples include tricot, Russell, and circular knitting. The knitting structure may be half knitting, reverse half knitting, double knitting, or the like. When polyurethane elastic fibers are used, one-way stretch or two-way stretch may be used. By cross-knitting with the polyurethane elastic yarn, a stretch property is exhibited in the knitted fabric, so that the fit and the elasticity in the case of innerwear are enhanced, which is more preferable.

When a dye having a low molecular weight and good leveling properties is selected, a plain appearance is exhibited. In addition, when a dye having a large molecular weight is selected, the thick part of the multifilament yarn is dyed deeply and the details are dyed lightly, so that a natural feeling of heather can be exhibited.

The methods for measuring various physical property values in the present invention are as follows. A. Worcester spots (Normal test) The thickness unevenness of the multifilament yarn in the yarn longitudinal direction is determined by Uster Tester manufactured by Zellbeger Worcester Co., Ltd.
3 was measured. The measurement conditions are as follows: yarn speed 25 m / min, twist: Z 0.5 bar, measurement time: 1.0 minute, measurement mode is normal, and the average deviation rate (U%) is measured. B. From the Worcester spot chart measured under the above conditions, the yarn length was 5 m.
The number of thick peaks per area was counted, and the thick and thin cycle length was determined by the following equation. Thick and thin cycle length [cm] = (500 [cm]) / (number of peaks counted) The peaks are counted as peaks having a width variation of 5% or more. C. Young's modulus TENSILON RTC- manufactured by Orientec Co., Ltd.
Measured at 1210. The measurement conditions were as follows: An SS curve (stress-strain curve) was obtained at a sample length of 5 cm, a tensile speed of 10 cm / min, and a chart speed of 50 cm / min, and was calculated from the initial tensile resistance and the fineness separately measured. D. Dryness, dryness, softness, and appearance of the knitted fabric A sensory test was performed by five subjects for each item, and evaluated on a four-point scale. Regarding dryness, dryness, and softness, "Excellent" is "◎", "Excellent" is "○", "Slightly superior" is "△", "Standard" is "X", Indicated by Regarding the appearance, those having a plain tone or a natural heather appearance were represented by “○”, and those having a degraded natural appearance were represented by “x”.

す。Example 1 The relative viscosity ηr in sulfuric acid was 2.
65 nylon 6 polymer was melt spun at a spinning temperature of 265 ° C. and a spinning speed of 800 m / min to obtain a multifilament undrawn yarn having a 89 dtex, 13 filament trilobal cross section. The undrawn yarn is drawn using the drawing device of FIG. 1 at a supply roller speed of 300 m / min, a slit heater temperature of 100 ° C., and a drawing roller speed of 600 m / min (drawing ratio of 2 times). Yarn was obtained. Worcester spots of the obtained multifilament yarn had an average value of 8.15%,
Thin and long cycle length is 7.6cm, Young's modulus is 9.9cN / dt
ex, the degree of irregularity was 2.1. Next, the polyamide-based multifilament yarn is arranged on the front, 44 dtex and a 5-filament polyurethane elastic yarn are arranged on the back, and 32
A gauge half tricot was knitted. The obtained half tricot was refined, relaxed, dried, and heat-set by a conventional method, dyed, and sewn to obtain a slip. The obtained knitted fabric and slip had a natural heather feeling, were excellent in dry feeling, dry feeling, softness, and were comfortable to wear. Table 1 shows the results.

す。(Examples 2 and 3, Comparative Examples 1 and 2) A knitted fabric was produced in the same manner as in Example 1 except that the drawing ratio was changed by changing the speed of the supply roller in drawing the undrawn yarn. . Example 2 was stronger in heather than Example 1, but was excellent in dryness and softness.
Example 3 was close to a plain tone and inferior to Example 1, but was excellent in dry feeling, dry feeling and softness. Comparative Example 1 was excellent in dryness, dryness, and softness, but was too strong in heather and impaired the natural appearance. Comparative Example 2 was plain in appearance and lacked a dry feeling and a dry feeling. The results are shown in Table 1.

No. 20 nylon 6 polymer was melt spun at a spinning temperature of 280 ° C. to obtain an undrawn yarn, which was drawn at a draw ratio of 2.43 times to obtain a polyamide-based multifilament. The other conditions were the same as in Example 1. Although the softness was lower than that of Example 1, a knitted fabric excellent in dry feeling and smooth feeling could be obtained. The results are shown in Table 1.
