DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention is, the most scratch look easy heel
The present invention relates to a heel protection sock that is doubled to ensure durability and heat retention, and to prevent cracking, bulkiness and the like of the heel.

[0002]

2. Description of the Related Art
Socks because most scratches look easy heel part, are or organized into the plantar portion especially strong in, for example, increasing the thickness of the heel portion, or double knitting. The present applicant has disclosed a Japanese Patent Application No. Hei 2 (1994) as a sock that can make this heel part durable and prevent cracking and bulkiness of the heel.
-252988 has already been submitted.

The present invention is an improvement of the invention of the prior application, and provides an excellent sock which is more excellent in protection of the heel portion and which is gentle to the skin and which prevents cracking and roughening of the heel. ..

[0004]

The gist of the present invention will be described with reference to the accompanying drawings.

[0005] One side of the cloth 4 does not impair the elasticity of the cloth 4.
Oddly thin synthetic resin film 3 is cut off breathability was coated, adhered to the skilled cloth 4 only peripheral edges of the sock 1 on the inner side of the heel veils 2, bonding the periphery inside of those fabric 4 Is formed in a double state separated from the shoe base.

[0006]

Since the thin synthetic resin film 3 is heat-bonded to the cloth 4, for example, the cloth 4 is provided with a ventilation blocking property without deteriorating the elasticity. Since that inside example heat bonding of the heel veils 2 of an equivalent fabric 4 imparted with the ventilation blocking periphery only sock 1, the outside air together with those fabric 4 will be reinforced flaws seen easily heel veils 2 Is blocked from being ventilated to the heels, and exhibits warmth and becomes a warm sock, and at the same time, also exhibits moisturizing. The heel that has already developed will exhibit a healing action.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As the cloth 4, a knitted sheet of, for example, about 50 denier is used, but a woven cloth may be used. A thin polyurethane synthetic resin film 3 having a thickness of, for example, about 7 microns is heat set on one surface of the cloth 4. This cloth 4 which has been subjected to this ventilation blocking processing (waterproofing) is applied to the inside of the heel concealing portion 2 of the sock 1 through a urethane adhesive synthetic resin film 5 cut in a ring shape or by direct heat bonding. The figure shows a case where only the peripheral edge portion is adhered, and the portion other than the peripheral edge portion of the cloth 4 is formed in a double state separated from the shoe base.

At this time, the cloth 4 adhered to the sock 1 is softly in contact with the skin because the polyethylene terephthalate synthetic resin fiber is adhered directly to the heel, and the cloth 4 is made of a highly elastic sheeting. The polyurethane-based synthetic resin film adhered to this is also thin and highly stretchable, so that even when the entire surface is adhered, the expansion of the cloth 4 can be performed.
It is a very easy-to-wear sock that adapts to the movement of the foot without compromising shrinkage .

Further, although the equivalent fabric 4 of synthetic resin film 3 adhered to is also directly heat bonded to the sock 1, very strong when you bonded via an adhesive synthetic resin film 5 of a urethane-based as shown in Fig. Glued.

[0010] Further, since the synthetic resin film 3 is stuck to the cloth 4, the ventilation is shut off, and since the heel concealing portion has a free double structure, the air inside stays there. Because of that, it has good heat retention and moisture retention,
Cracking of the heel and bulky roughness are prevented and healed. Further, since the cloth 4 adhered to the heel portion of the sock 1 is adhered by heat setting, there is no need to double the cloth by sewing or the like, and the production process can be significantly shortened.

[0011]

According to the present invention because the structure described above, those
The cloth is stretchable because a thin synthetic resin film is applied to the cloth
Air permeability is impaired without impairment. This ventilation barrier
Only the peripheral part of the cloth with the
The cloth should reinforce the fragile heel concealed part because it adheres
And the outside air is blocked from venting to the heel
To keep you warm and sock while keeping you moist
In addition to the heat retention,
Prevents cracking and bulkiness and has already occurred
Heel protection socks exhibiting excellent healing properties on the heels.
