The first characteristic of the characteristics of the supply yarn used in the present invention is that it is a polyethylene terephthalate having a latent water absorbing property, and it is preferably a polyethylene terephthalate containing 95% by weight or more of polyethylene terephthalate.

The reason why the specific polymer component composite hollow fiber is used is to prevent a decrease in the strength and elongation of the yarn after the alkali weight reduction, which will be described in detail later. That is, since component B, which has a high alkali weight loss rate, consumes alkali relatively selectively, it is possible to minimize the decrease of component A from its original high elongation as much as possible.

[0007] The reason for the hollow cross section yarn is that the texture of the textile constituted by the hollow cross section yarn is similar to cotton. This is a very important factor when industrializing the present invention. In other words, the widespread use of cotton products means that consumers prefer the feeling of cotton, and in industrializing the present invention, expressing sensitivity as important as the water absorbing function of the present invention. Because you can. The hollow ratio at this time, that is, the ratio of the cross-sectional area of the hollow portion to the apparent fiber cross-sectional area is 10%.

[0008] A second characteristic of the characteristics of the supply yarn is that the multifilament yarn in which a portion (thick portion) where the diameter of a single fiber is large exists at high frequency and is not unevenly distributed. As such characteristics, (1) the index indicating the frequency of the presence of the thick part is 45% or more, preferably 65% or more of the foci wavelength, and (2) the fact that the thick part is not unevenly distributed. As an index, Worcester U% (middle cycle) is 1%
It is necessary to satisfy the following at the same time.

[0010] In addition, S 1 since the presence of the yarn unevenness of the wavelength of less than meter is not substantially observed even if the normal drawn yarn that does not exist in the chic part is there is a yarn unevenness of the wavelength of more than a few meters
Is considered to be mainly due to the presence of the thick section. The K value of a normal drawn yarn is at most 30%, and K ≧ 45% when a thick portion is formed under specific drawing conditions. In the case of a yarn having such a K value, the presence of a thick portion between single fibers may be unevenly distributed (for example, Japanese Patent Publication No. 63-17933), but in this case, the wool U% (middle period) is 1%. Will be exceeded. In other words, the supply yarn used in the present invention generally has a thick portion in an arbitrary cross section of the original yarn, and has a very small variation (variation in thickness) of the sum of the single fiber areas constituting the arbitrary cross section. .

The raw yarn having such a characteristic is obtained by unstretching a component A and a component B, for example, by using a side-by-side composite hollow spinneret shown in FIG. 2 so as to have a hollow ratio of 10 to 30%. Winding the undrawn yarn several times around a heat roller having a temperature below the crystallization temperature of the undrawn yarn and above the glass transition temperature between a pair of rollers, and drawing at a ratio at which the residual elongation at break after drawing is 70 to 90%.

The raw yarn 1 thus obtained is as shown in FIG.

The false twist yarns 9 and 10 are formed by a false twist device including a delivery roller 5, a second heater 6, a second delivery roller 7, and a winder 8. At this time, it is important to keep the hollow structure of the original yarn as much as possible. Thereby, the cottony feeling, which is the sensible element of the present invention, is maintained. If the cross-sectional deformation becomes large, the texture becomes coarse and hard, which is not preferable. The appropriate temperature of the first heater 3 which most affects the sectional deformation is 17
If the temperature is 0 ° C. or less, preferably 150 ° C. or less, substantially no cross-sectional deformation occurs.

The draw ratio at the time of false twisting is appropriately 1.08 ± 0.02 times when the twisting tension is about 0.12 g / d. It becomes smaller than the stretching ratio to be performed. This is as described above.
In the supply yarn used in the present invention, a thick portion exists in almost any cross section of the original yarn without uneven distribution of the thick portion between the single fibers [in other words, a portion where the single fiber diameter is small (a thin portion).
In general, there is a thin portion in any cross section of the original yarn without uneven distribution], which reflects that the variation in the sum of the area of the single fibers constituting any cross section (thickness unevenness) is extremely small. Because they do.

The behavior of the thick part at the time of false twisting is as follows. Since the thick part has a higher elongation than the thin part, it is stretched by twisting stress, heat-fixed by the first heater 3, untwisted, and temporarily twisted. The twist yarn 9 is obtained. Alternatively, the twisted yarn 10 is stabilized by the second heater 6 as necessary. The obtained false twist yarn is the fourth
As shown in the model in the figure, the false twisted yarns 9 and 10 have a shape in which a large number of pallets 11 and loops 12 are present. When this false twisted yarn is formed into a tubular knitted fabric and dyed with a disperse dye under boiling water, the tarmi and the loop are deeply dyed.

Sufficient water absorption can be obtained by using a commonly used technique for the alkali weight reduction process and setting the weight loss rate to 3% or more and 45% or less. A feature of the present invention is that sufficient water absorption can be obtained even when the alkali weight loss rate is extremely low (around 5%). Generally, the single fiber is damaged by the alkali weight loss, and the physical performance such as the tear strength of the woven or knitted fabric is reduced. However, the present invention is also advantageous in this respect.

The reason for this is considered to be the above-described structure of false twisted yarn in which a large number of loops 12 and tarmi 11 having a coarse fiber internal structure exist. In other words, the fiber inside structure around the false twisted yarn has a rough structure.
, Alkali weight loss progresses more easily than that of the syn part, and in particular, component B weight loss progresses more easily, consumes alkali in an alkali bath in a short time, and produces a water absorbing effect by a mechanism described later. On the other hand, in a thick part having a slow weight loss rate, the progress of weight loss is reduced, and the above-mentioned decrease in physical performance is significantly prevented. Therefore, a woven or knitted fabric having high water absorption and preventing a decrease in physical performance can be obtained. The yarn structure in which a single fiber having high water absorption performance exists around the false twist yarn is also considered to be a major factor in obtaining high water absorption.

Further, the relationship between the alkali weight loss behavior and the water absorption will be described in detail. As shown in the model in FIG. 5, when the weight loss rate of the component B is about 5%, a streak-like groove is almost formed along the fiber axis. In the vicinity of 10% to 30%, in addition to the groove 13, a hole 14 partially penetrates into the hollow portion, and 45%
In the vicinity, in addition to the groove 13 and the partial hole 14, a portion 15 lacking dissolution is seen, and if it exceeds 50%, the missing portion 1 is found.

Component A has almost no change in appearance when the weight loss rate is about 5%, and an elliptical weight loss mark observed in a normal alkali weight loss product at about 10 to 30%.
In the vicinity, cracks 16 are formed partially at right angles to the fiber axis, and when it exceeds 45%, a large number of cracks 16 that have grown significantly are observed.

These results are obtained by dyeing the weight-reduced knitted fabric with a disperse dye under boiling water, sampling the densely dyed monofilament protruding from the knitted ground, and observing the sample with a scanning electron microscope. If the weight loss treatment is not carried out, no water absorption is observed, and since the weight loss rate is 3% or more and 45% or less, extremely effective water absorption is exhibited.
It is considered that the capillary phenomenon due to the formation of the streak-like grooves 13 is dominant in improving the water absorption. On the other hand, the bursting strength of the knitted fabric decreases gradually until the alkali weight loss rate is around 45%.
If it exceeds about 45%, it drops sharply. Therefore, industrially, it is necessary to keep the alkali weight loss rate at 45% or less from the viewpoint of quality control.

Comparative Example 1 The surface temperature of the heat roller was 65 ° C.
A raw yarn was obtained under the same conditions as in Example 1 except for the above. This yarn had a fineness of 105 d, a breaking elongation of 87%, a Uster U% (middle period) of 1.54%, and a K value of 75%. The false twisting conditions were the same as in Example 1 except that the stretching ratio was 1.15 times. Subsequently, a knitted fabric was formed under the same knitting conditions as in Example 1,
The weight loss rate was changed and the water drop disappearance time was measured. Table 2 shows the results
As shown in the figure, there was a large variation in the measured values.
It is presumed that the reason for this is that the yarn of this comparative example has a structure in which the thick portion is unevenly distributed.
