Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to the first pantyhose or stockings (hereinafter simply referred to as stockings) that have excellent transparency and durability. .

(Conventional technology) Conventionally, support stockings that put pressure on the ankles, bulges, thighs, hips, etc., relieve the feeling of bruises, and improve cosmetic appearance are usually made of nylon. It was obtained by inter-knitting a multifilament yarn or a covered yarn made by winding a nylon multifilament yarn with normal physical properties around a polyurethane synthetic fiber yarn. S) If you make the thread thicker in order to increase the strength, the transparency will disappear, and on the other hand, if you increase the thread usage to satisfy the transparency, the strength will decrease and the protrusion will become uneven.

(Problems to be Solved by the Invention) The object of the present invention is to obtain two-port hanty stockings that have excellent d4 clarity, yet have excellent durability and tightness.

(Measures to solve the problem) At the end of the first outburst, at least the leg part is used as a core yarn, and the

It is a support pantyhose made of synthetic m-fiber multifilament yarn based on Noshinami or its processed yarn, or one-course strawberry, which is attached to the father's mouth. In the present invention,
The rubber-like elastic fiber yarn constituting the core yarn of the covered yarn includes natural rubber, synthetic rubber, polyurethane-based synthetic fiber yarn, butadiene rubber fiber yarn, etc., but polyurethane-based synthetic fiber yarn is preferred. The fiber thickness must be 10 to 30 deniers, more preferably 10 to 20 deniers. Maki: Iita Saga 1
If it is less than 0 denier, sufficient tension cannot be obtained, and if it exceeds 30 denier, the thickness of the covered yarn will increase and the tension will be too strong, which is not good. In addition, it is not good because it becomes impossible to obtain sahot stockings with excellent transparency. The polyamides constituting the covering yarn of the covered yarn and the polyamide synthetic fiber multifilament yarn to be knitted with the covered yarn include, for example, polycaprolactam (nylon 6), polyhexamethylene adipamide (nylon 66), polyhexanthyl >Y2, lTi

A particularly preferred polyamide-based composite fabric having a relative viscosity of 6.0 to 95 r/d can be obtained by melt-spinning a polyamide having a relative viscosity of 3.0 to 4.5, and then stretching it.
