Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stocking having a comfortable wearing comfort, a stocking having an excellent fatigue relieving effect, and a manufacturing method capable of easily and stably providing such a stocking.

[0002]

2. Description of the Related Art Heretofore, many techniques have been proposed for providing stockings having various characteristics. For example, in order to apply appropriate pressure to each part of the stocking, use a composite yarn or covering yarn to change the stitch size and thickness, change the knitting amount, and devise a knitting method to improve the stocking characteristics. Adjustment is made by JP-A-3-28780.
No. 1, JP-A-3-279403, and JP-A-4-279403.
It is proposed in Japanese Patent No. 18102.

[0003]

However, in such a conventional technique, a complicated operation of changing the stitch size and thickness, changing the knitting amount, changing the knitting method, and the like for each part,
It required a complicated knitting design, and the manufacturing required skill and precise control.

In view of the above problems of the prior art, the present invention provides a product having desired characteristics such as a stocking which is comfortable to wear and has an excellent effect of relieving fatigue regardless of the knitting method and the knitting amount. It is an object of the present invention to provide a method for easily and stably manufacturing, and significantly improving productivity and knitting cost.

[0005]

The present invention proposes the following means in order to solve the above-mentioned problems. That is, the stocking of the present invention is characterized in that the pressure applied to each part in the length (wale) direction is different in a region constituted by substantially the same amount of braid, and each lengthwise direction is different. It is characterized in that the parts are composed of fibers having different shrinkage rates of boiling water, and the stress at the time of elongation recovery of each part in the length direction is different. Further, it is characterized in that the pressure applied to each part on the same circumference (course) is different, and each part on the same circumference is composed of fibers having different boiling water shrinkage rates. In addition, the stress at the time of extension recovery of each portion on the same circumference is different.

[0006] Such a stocking manufacturing method comprises a plurality of independent heating zones divided in the length (wale) direction of the stocking, or in the length (wale) direction and width (course) direction of the stocking. Using a heat setting device, under heat setting conditions for each section, and
It is characterized in that the stockings are heat-set while attached to the legs.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Conventionally, in order to provide a stocking excellent in various characteristics, the thickness and knitting amount of the thread are changed, the knitting method is changed, the complicated operation and the complicated operation are performed for each part. The reality is that it was manufactured by making full use of the knitting design.

The present invention eliminates the complexity and complexity of the prior art, makes a diligent study on whether or not desired characteristics can be easily achieved, and applies a heat set peculiar to each part to Even if you do not change the amount of knitting and the knitting method,
It has been found that a stocking having desired characteristics can be easily provided.

That is, in the conventional stocking having a comfortable wearing feeling, the compression force and the tightening force of each part in the length (wale) direction from the arch to the ankle, the calf, and the thigh are optimized. Therefore, it was manufactured by changing the amount of knitting and the knitting method. The present invention
It is characterized in that the pressure and tightening force of each part are optimized by the difference in heat setting conditions.

That is, the stocking of the present invention is characterized in that the pressure applied to each portion in the length (wale) direction is different in the region constituted by substantially the same amount of braiding. Even if the stocking of the present invention is configured with a uniform amount of braiding, by adjusting the heat setting conditions of each part independently, the pressure and tightening force of each part are optimized. It has characteristics. To further elaborate on this point, from the arch of the stocking to the ankle,
Since each part in the length (wale) direction reaching the calf and thigh is heat set under independent conditions, the knitting yarn fibers forming each part have independent heat histories. As a result, it is characterized in that it shows specific different boiling water shrinkage rates and stresses upon extension recovery. Similarly, according to the method of the present invention, each site on the same circumference (course) can be heat-set under independent conditions, and each site shows different boiling water shrinkage and stress at extension recovery. It has features.

In addition, in the present invention, in addition to the one in which the whole stocking is constructed with a uniform weaving amount and the heat setting condition of each part is independently adjusted,
For example, at least one part (region) of each part (region) in the length (wale) direction from the arch part of the stocking to the ankle part, the calf part, and the thigh part has a different weaving amount. It may be used to independently adjust the heat setting conditions of at least one site (region).

The stocking of the present invention is manufactured by using a specific heat setting device composed of independent heating zones divided into a plurality of sections in the length (wale) direction of the stocking, preferably at least three sections. It is possible to freely adjust the thermal history to a form in which the thermal histories are abruptly changed or a form in which the thermal histories are continuously changed at adjacent boundaries of regions corresponding to respective parts of the set product. In the heat setting device of the present invention, a structure in which one housing is divided into a plurality of heating chambers is preferable from the viewpoint of thermal efficiency, but a structure in which a plurality of heating chambers are independently provided may be used. Such heating chambers are preferably installed for each part of the arch, ankle, calf, and thigh of the stocking, and further subdivided in the length (wale) direction or the circumferential (course) direction. Good. In addition to stockings, according to the form and function of the product to be heat-set, necessary parts are divided and each has an independent heating chamber, and various products can be set by heat-setting a desired part, for example. Bra, girdle, pants, shirt,
It can also be applied to gloves.

As a heat source of the heater constituting the heating chamber, electric heat, electromagnetic heat, microwave, infrared ray, various fuel gases, steam, superheated steam, hot water, organic heat medium, metal heat medium, etc. can be adopted. It is possible to employ at least one heat source of

As a heat setting condition by the heating means, a temperature in the range of 100 ° C. to 400 ° C. is adopted.
Since the setting effect differs depending on the heating means used, the adopted temperature is appropriately changed by the heating means. Generally, the moist heat means has an excellent heat setting effect, and therefore a lower temperature is set as compared with the dry heat means.

In the heat setting process, the stockings are processed in a state in which they are fixed to the leg mold. As such a leg type, one having an expansion / contraction mechanism and a volume increasing / decreasing mechanism enables tension processing and relaxation processing, and is convenient for adjusting pressure and texture.

In the method of the present invention, the heat setting effect is increased and the braided amount (yarn feeding amount) is reduced on the part where the braiding amount (yarn feeding amount) is increased and the applied pressure is adjusted to be low. By lowering the heat setting effect on the part where the contact pressure is increased, the contact pressure can be adjusted. Specifically, conventionally, the yarn feed amount was changed finely for each region in the length direction, for example, over 20 places, and the applied pressure for each region was adjusted.
In the present invention, for example, from the tip of the foot to the calf (A)
Has the same amount of yarn supplied, but the braid amount is lower than other parts, from the upper end of the calf to the lower end of the thigh (part B)
It seems that the amount of yarn is gradually increased to gradually increase the amount of knitting, and that the amount of yarn is the same from the thigh to the abdomen (C), but the amount of knitting is higher than other parts. By preparing a stocking knitted fabric with a simple knitting design and changing the heat setting conditions in the length direction with a boarding set device, it is possible to achieve the adjustment of the pressing pressure that can oppose the conventional product.

If a knitting yarn having a higher heat setting property is used, a tubular knitted fabric having the same amount of yarn to be fed from the toes to the abdomen is prepared, and the heat setting conditions in the length direction are changed.
It is also possible to adjust the desired pressure in the length direction.
In this case, as compared with the conventional stocking, the stocking according to the method of the present invention is characterized in that the applied pressure is different depending on the part in the length (wale) direction in the region constituted by substantially the same braid amount (feed amount). There is.

The stockings referred to in the present invention include those made of known knitting yarn, for example, knitting yarn containing polyurethane elastic fiber or polyether ester elastic fiber, and 100% elastic fiber. And a covering thread composed of such an elastic fiber as a core thread and a non-elastic fiber such as polyamide fiber or polyester fiber as a covering thread, and various composite elastic threads of elastic fiber and non-elastic fiber can do. As such a knitting yarn, one having a total fineness of 5 to 250 denier can be preferably used. The knitting yarn may be composed of a mixed yarn composed of fibers of large fineness and fineness, and further contains ultrafine fibers having a single fiber fineness of 0.1 denier or less as the fineness of fibers. May be.
