The present invention relates to a method for producing a polyester woven or knitted fabric having good drapability and extremely excellent hand feel. Conventionally, various proposals have been made to improve the feel and drape properties of woven and knitted materials, but nothing satisfactory has yet been achieved. The present inventors have focused on the fact that the polyester filament yarn spun at high speed has slight spontaneous elongation properties depending on the drawing conditions and the subsequent heat treatment conditions, and also found that The present invention was achieved by skillfully utilizing the physical properties of polyester filament yarn. That is, the present invention uses polyester filament yarn that can be woven and knitted to provide spontaneous extensibility, with a boiling water yield of 10% or more and a breaking elongation of 80% or less, obtained by high-speed spinning and low-temperature stretching, Next, the woven or knitted fabric is subjected to relaxation heat treatment to sufficiently shrink the polyester filament yarn in the woven or knitted fabric and impart spontaneous elongation, and then heat treated at a temperature higher than the relaxation heat treatment temperature to make the polyester filament yarn spontaneously elongate. A method for producing a woven or knitted fabric characterized by elongation. The present invention will be explained in detail below. The method of the present invention involves weaving and knitting using polyester filament yarn that can impart spontaneous extensibility, and in this case, the boiling water shrinkage rate of the polyester filament yarn is 10% or more and the breaking elongation is 80% or less. There is a need. Polyester filament yarns having spontaneous extensibility are produced by spinning a condensation polymer under conditions that do not cause high crystallinity and then stretching it simultaneously or afterwards, as described in Japanese Patent Publication No. 41-12052. The filaments can be oriented by heating for a period of time to obtain a spontaneously extensible polyester filament yarn under conditions that permit at least 20% structural shrinkage without producing high crystallinity. Proposed. however,
Since the yarn produced by such a method shrinks at the yarn stage, it is undesirable for the boiling water shrinkage rate to be more than 10%, and the yarn will elongate rather than shrink. The elongation is also 100% or more, which reduces the workability of weaving and knitting, and the quality of the resulting woven or knitted fabric is degraded due to "sink marks" and "uneven tension." On the other hand, the polyester filament yarn capable of imparting spontaneous extensibility used in the method of the present invention can be obtained as follows. That is, filament yarn made of linear terephthalate polyester is spun at a spinning speed of 1500 m/min to 4500 m/min.
The fibers are spun in the range of m/min and then drawn at a low temperature. As the stretching temperature, a range of 20°C to 80°C is effectively used, and more preferably a temperature of -20°C, which is the secondary dislocation point.
The stretching ratio is effectively used at a temperature of approximately 0.7 times the cutting elongation of the undrawn yarn. If the spinning speed is less than 1500 m/min, the orientation of the yarn before drawing is low and it is amorphous, so even if the yarn is drawn at a low temperature without increasing the crystallinity, it will not be possible to obtain the yarn. The drawn yarn is very unstable, and its physical properties change just by leaving it at room temperature.Because of this change over time, the drawing process is usually discontinuous. This is not desirable because it cannot provide supplies. In addition, when the above-mentioned spinning speed exceeds 4500 m/min, the resulting yarn has a low boiling water shrinkage rate, and even if such a yarn is drawn at a low temperature, the resulting drawn yarn has a boiling water shrinkage rate of 10% or more. Otherwise, the object of the present invention cannot be achieved. The stretching temperature is preferably up to 80° C. in order to achieve a crystallinity of at most 35%, and the yarn thus obtained exhibits spontaneous elongation upon subsequent treatment. In other words, polyester filament yarn that can impart spontaneous extensibility is obtained by low-temperature drawing of yarn obtained by high-speed spinning, so its crystallinity is as low as 20%, and its orientation is similar to the degree of birefringence. Δn is in the range of 0.10 to 0.12, and at the same time satisfies boiling water shrinkage of 10% or more and cutting elongation of 80% or less. In addition, prior to the above-mentioned low-temperature drawing, the polyester filament yarn is heated in advance to a temperature higher than the secondary transition point.
The material was heat treated at 130℃ and then stretched at low temperature.
The physical properties of the resulting drawn yarn become more stable,
It can be used to produce woven or knitted fabrics of good quality. The polyester filament yarn obtained at a spinning speed of 1200 m/min to 5000 m/min was heat treated at a temperature of 105°C (some yarns were drawn without this heat treatment), and then the elongation at break of the undrawn yarn was 70°C. %, and low-temperature stretching was carried out at the temperatures listed in Table 1. At the same time as measuring the boiling water shrinkage rate and cutting elongation of the obtained polyester filament yarn, the polyester filament yarn was taken on a skein, and the skein was treated in hot water at a temperature of 100°C for 30 minutes, and after the treatment, it was allowed to air dry. After that, Rei no Haranaga
l 0 was measured. The skein was heat-treated again at a dry heat temperature of 180° C., the skein length l 1 was measured, and the spontaneous elongation rate was determined as l 0 −l 1 /l 0 ×100 (%). Also, using the polyester filament yarns (75 de/36 fils) corresponding to each spinning speed, a plain weave was woven at a warp density of 42 threads/cm and a weft density of 40 threads/cm, and the woven fabric was heated at a temperature of 100°C. After that, the fabric was heat treated at a temperature of 180°C to finish. Table 1 shows the evaluation of the physical properties of the polyester filament yarn and the drape properties of the fabric using the same.

[Table] Indicates that it does not lengthen and contracts.
As is clear from Table 1, the spinning speed is 1500
When the speed was less than m/min, color spots appeared, which appeared to be due to changes in the physical properties of the polyester filament yarn over time, and spontaneous elongation was not observed even in the heat-treated yarn. In addition, even if the spinning speed is in the range of 1500 m/min to 4500 m/min, the drawing temperature is as high as 100°C.
Spontaneous extensibility could not be obtained, and the object of the present invention could not be achieved. In addition, when the spinning speed exceeds 4500 m/min (in Table 1, the spinning speed is 5000 m/min), the boiling water shrinkage rate of the polyester filament yarn is low and it is not possible to make the yarn spontaneously extensible. The object of the present invention could not be achieved. As described above, in the method of the present invention, after high-speed spinning, polyester filament yarn drawn at low temperature is woven and knitted, and then the woven or knitted fabric is subjected to a relaxation heat treatment. It is important that the material is sufficiently shrunk. As the temperature for this relaxation heat treatment, a temperature above the secondary dislocation point to 130° C. is effectively used. Furthermore, the treatment time for such relaxation heat treatment is 30~
Approximately 60 minutes is effective. If the temperature of the relaxation heat treatment is lower than the second-order dislocation point, the yarns in the woven or knitted fabric will not shrink sufficiently and it will be difficult to form the woven or knitted fabric into a dense and bent structure, which is not preferable. Further, if the relaxation heat treatment temperature exceeds 130°C, the degree of crystallinity increases and it is difficult to impart spontaneous elongation properties to the yarn in the woven or knitted fabric, which is not preferable. In addition, the time for the relaxation heat treatment must be determined in relation to the temperature, taking into account that the crystallinity does not exceed 35%. It is best to take about a minute. The polyester filament yarn used in the method of the present invention has a high boiling water shrinkage rate of 10% or more,
Further, sufficient shrinkage can be achieved by the above-mentioned relaxation heat treatment. FIG. 1 is a cross-sectional view schematically showing a cross section of a fabric obtained by the method of the present invention,
Figure 1A shows the state of the gray fabric, which has not yet contracted, so the bending of the threads in the fabric is not large. FIG. 1B shows the state after the relaxation heat treatment, in which the yarns shrink and the fabric density increases, and the yarns in the fabric can be bent significantly. That is, the woven or knitted fabric has a dense structure obtained by sufficiently shrinking the polyester filament yarn, and has a structure in which the yarns in the woven or knitted fabric are mutually bent. As described above, the woven or knitted fabric produced by the method of the present invention has a bent and dense structure, and the polyester filament yarn that makes up the woven or knitted fabric exhibits spontaneous elongation. It helps to reduce the contact pressure between the yarns, and works synergistically with the bending and dense structure to create greater flexibility, resulting in good drapability and excellent resilience. Woven or knitted fabrics can be obtained. The subsequent heat treatment is desirably carried out at a temperature higher than the relaxation heat treatment, at which the crystallinity of the spontaneously elongated thread progresses and becomes thermally stable. Furthermore, the method of the present invention is advantageous because it can handle yarns with a cutting elongation of 80% or less, which reduces the quality of woven and knitted fabrics from the problem of poor handling workability, which is the case with conventional spontaneously extensible yarns. This can prevent the decline. The present invention will be explained below using examples. Example A polyester filament yarn spun at a spinning speed of 3500 m/min was heat treated at a temperature of 110°C, and then stretched at a draw ratio of 1.55 times at a temperature of 25°C, with a boiling water shrinkage rate of 25% and a cutting elongation rate of 40%. Got the thread. Next, the drawn yarn is woven into a plain woven fabric having a density of 42 threads/cm in warp and 40 threads/cm in weft, and the woven fabric is subjected to relaxation heat treatment at various temperatures for 60 minutes. The drapability was evaluated by heat treatment at a certain temperature. The results are shown in Table 2. Nos. 1 to 4 showed good drape properties, but No. 5 had poor drape properties.

[Table] In Nos. 1 to 4, the temperature is relatively low during the relaxing heat treatment, so the polyester filament yarns constituting the fabric contract to spontaneously elongate, and in No. 5, the relaxing heat treatment This is thought to be because crystallization is immediately promoted and spontaneous elongation does not occur during subsequent heat treatment.
