う欠点を有している。2. Description of the Related Art Conventionally, a method of using elastic yarns for producing stretchable fabrics having excellent elastic recovery performance has been widely used. Polyurethane-based elastic yarn has been the most representative type of elastic yarn. However, although the polyurethane elastic yarn has excellent elastic recovery performance, it has the drawback of being inferior in heat resistance, chemical resistance, and weather (light) resistance.

にも種々の提案がなされている。In order to solve these drawbacks, in recent years, a highly crystalline polyester such as polyethylene terephthalate or polybutylene terephthalate is used as a hard segment,
Polyetherester-based elastic yarns having polyalkylene glycol as a soft segment have been developed, and various proposals have been made for their usage.

るが，それぞれに長所と短所を有している。In the case of interwoven or knitting such an elastic yarn on a cloth, it is not possible to obtain a cloth of uniform quality unless the elasticity of the elastic yarn is controlled. For that purpose, the yarn length of the elastic yarn is controlled. It is necessary, and there are roughly two methods.
One is a method in which the elastic yarn is pre-coated with other fibers under a certain tension and used, and the other is a method in which the elastic yarn is used alone by using a positive feeding device. ， Each has its advantages and disadvantages.

品の種類により銘柄が増え，ロスが増加する。しかし，
この前工程により，織編工程では積極送り出し装置を使
用して弾性糸長をコントロールする必要はない。In the former method, a step of entwining with another fiber by covering, air entanglement, etc. is required by using an active feeding device for supplying a constant amount of yarn by rotating the elastic yarn itself in advance. Other fibers need to be selected and prepared, the production process will become longer, and the number of brands will increase and the loss will increase depending on the type of product. However,
Due to this pre-process, it is not necessary to control the elastic yarn length in the weaving process by using a positive feeding device.

合も同様である。In the latter method, the produced elastic yarn can be directly used in the weaving process and the loss is small, but an active feeding device is required. Therefore, when it is used for knitting, each knitting machine requires a positive feeding device, which becomes a bottleneck in production, and when the type of coated elastic yarn is predetermined, the former method is efficient. It is often used in the same way as in the case of polyetherester type elastic yarn.

はない。As described above, although the polyetherester elastic yarn has been widely used, the elastic recovery performance is inferior to that of the polyurethane elastic yarn, and the coated elastic yarn made by this also has an elastic recovery performance. Since it is inferior, various proposals and improvements have been made. For example, in the manufacturing process of elastic yarns, JP-A-58-91819 discloses a method of heat-treating a polyetherester-based elastic yarn in the spinning process. However, in this method, it is necessary to set the spinning speed of the elastic yarn to an ultra-low speed and to lengthen the heat treatment time, which is disadvantageous in that the size of the apparatus is increased, the cost is increased, and the workability is deteriorated. Further, JP-A-6-136613 discloses a method of aging the produced polyetherester-based elastic yarn in the form of cheese at low temperature and further at room temperature. However, this method requires a maturing room and long-term mating, and further,
This is not the best method because it causes differences in the inner and outer layers of cheese and ripening on the sides.

That is, according to the present invention, when a coated elastic yarn in which a polyetherester elastic yarn is coated with an inelastic fiber is manufactured, the polyetherester elastic yarn has a draft ratio of 0.75 to 1.2.
A method for producing a coated elastic yarn, which comprises subjecting a non-elastic fiber to a covering with a twist number of 150 to 600 T / M and covering it while drafting it to 1.5 to 3.5 times after heat treatment at 5 times. It is a summary.

The polyether ester constituting the coated elastic yarn of the present invention needs to have at least one of polyethylene terephthalate and polybutylene terephthalate as a hard segment. Although there is no particular restriction on the mixing ratio of polyethylene terephthalate and polybutylene terephthalate, when the amount of polybutylene terephthalate is large, the elastic recovery performance is excellent, and when the amount of polyethylene terephthalate is large, the strength and elongation property is excellent. It may be appropriately selected according to the above.

It is also possible to have crimps due to false twist.

Therefore, the non-elastic fiber needs to be thicker and is often used. In the case of synthetic fibers, the combination of the thicknesses is (40d / 70)

The conditions of the heat treatment are temperature, time and draft rate. The heat treatment temperature depends on the manufacturing conditions and the melting point of the polyetherester elastic yarn, but if it is (melting point -120) ° C or higher,
A sufficient effect can be obtained in a time of 1 to 2 seconds. The draft rate is preferably as low as possible so that heat treatment can be performed with low tension, and 0.75 to 1.25 is good.

取られる。Next, the covering step of making two fibers into covered elastic yarns will be described. The draft is applied to the heat-treated elastic yarn, and the core of a hollow spindle at the center of a bobbin separately wound with non-elastic fiber is passed through and the non-elastic fiber is wound around the elastic yarn in the covering zone. The machine is not particularly limited. The heat treatment and the covering may be carried out on different machines or may be successively carried out on the same machine. If you want to continue with the same machine,
It is convenient to use a covering machine with a heater zone as outlined in FIG. In FIG. 1, the polyetherester-based elastic yarn 1 needs to control the length of the supplied yarn to be constant, and is fed by the positive feeding device 2 and held by the first roller 3 and the second roller 4
After being heat-treated by the heater 5 installed between and, a draft is given between the second roller and the third roller 7,
A non-elastic fiber 6 supplied from a bobbin installed on a hollow spindle covers the hollow spindle and winds it into a winding package 8.

る。The number of twists at the time of covering is determined by the combination of the elastic yarn and the non-elastic fiber and the purpose of use, but at least 150 to 600 times / m is necessary. However, there are drawbacks such as yarn accumulation in the guides and reeds during interlacing and weaving. If the number of twists is increased more than necessary, not only the cost will increase, but also torque will be generated, which will hinder use. Consider and select the conditions under which a good coated elastic yarn can be obtained without causing these defects.

It is estimated that the elastic recovery performance can be stabilized while being improved.

It can be seen that the variation is smaller. Example 1,
In Nos. 2, 3 and 4, all the performances were improved as compared with Comparative Example 1, particularly in Examples 1 and 2, but in Example 2, since the draft ratio during heat treatment was low, the fineness was 48d. It's getting thicker.
