Abstract

The present invention relates to a method for manufacturing a knitted yarn for medical compression stockings, compression bandages, etc. and, more specifically, to a method for manufacturing a knitted yarn using an elastic spandex yarn as a core yarn and a nylon drawn textured yarn (DTY) as a covering yarn, thereby enabling a primary covering yarn and a secondary covering yarn to be wound in opposite directions to each other. According to the present invention, the elasticity and durability of a knitted yarn are improved, so that medical compression stockings knitted with the knitted yarn provide gentle but sufficient pressure and good wearing sensation but also prevent compression stockings being loose even when worn for a long period of time, thereby maximizing the product lifespan.

Description

의료용 압박스타킹의 편성사 제조방법 { Manufacturing method of knitting yarn for medical compression hosiery }Manufacturing method of knitting yarn for medical compression stockings { Manufacturing method of knitting yarn for medical compression hosiery }

본 발명은 의료용 압박스타킹 및 압박붕대 등의 편성사의 제조방법에 관한 것으로, 특히 탄성사를 중심으로 1, 2차의 커버링사를 권취시키도록 하여 편성사를 편성함으로써, 편성사의 연신율과 강도를 향상시킬 수 있을 뿐만 아니라, 이러한 편성사로 편성된 의료용 압박스타킹의 신축성 및 압박감과 착용감을 향상시키도록 하고, 사용수명을 최대화할 수 있도록 한 것이다.The present invention relates to a method for manufacturing a knitted yarn such as medical compression stockings and a compression bandage, and in particular, to improve the elongation and strength of the knitted yarn by knitting the knitted yarn such that the primary and secondary covering yarns are wound around the elastic yarn. Not only can it be possible, but also to improve the elasticity, pressure, and fit of the medical compression stockings knitted with such a knitted yarn, and to maximize the service life.

일반적으로 의료용 압박스타킹 또는 압박붕대는 하지정맥류 및 붓는 현상 등의 치료나 예방을 목적으로 발이나 발목, 종아리 및 허벅지 등에 착용하여, 혈액 순환과 혈액의 역류 등을 방지하도록 하고 있다.In general, medical compression stockings or compression bandages are worn on the feet, ankles, calves, and thighs for the purpose of treating or preventing varicose veins and swelling, etc. to prevent blood circulation and backflow of blood.

이러한 의료용 압박스타킹 및 압박붕대는 주로 탄성사 등을 이용하여 신축성이 높은 원단을 편성하여 제조하였으며, 원단의 신축성을 통해 착용된 신체부위를 압박하도록 하였다.These medical compression stockings and compression bandages were mainly manufactured by knitting a highly elastic fabric using elastic yarn, etc., and the worn body part was compressed through the elasticity of the fabric.

근래에 와서는 의료용 압박스타킹과 압박붕대의 표면과 내면을 편성하는 원사를 각각 상이하게 하여, 내면부의 착용감과 표면부의 내구성을 향상시키도록 하고 있다.In recent years, the yarns for knitting the surface and inner surfaces of medical compression stockings and compression bandages are different, respectively, to improve the fit of the inner surface and the durability of the surface portion.

상기한 의료용 압박스타킹 또는 압박붕대를 제조하는 방법에 관련한 종래의 선행기술문헌으로는, 대한민국 등록특허공보 제10-1363802호의 발명의 명칭 ‘코어방적사를 사용하여 짜여진 차별압박스타킹 ’이 있다.As a prior art document related to a method of manufacturing the above-mentioned medical compression stockings or compression bandages, there is an invention titled 'differential compression stockings woven using core spun yarn' in Korean Patent Publication No. 10-1363802.

상기한 종래의 발명은 착용자의 하부 하지에 하지의 길이를 따라 변하는 압박력을 제공하도록 하고, 차별압박스타킹의 외측 단부와 내측의 개방 단부 사이에서 이음새 없이 연장되는 스타킹 부분을 포함하도록 한 것이다.The above-described conventional invention is to provide a compressive force varying along the length of the lower extremities to the wearer's lower extremities, and to include a stocking portion extending seamlessly between the outer end and the inner open end of the differential compression stocking.

그리고, 대한민국 등록특허공보 10-2079587호의 발명의 명칭 ‘구리 나노 압박 스타킹 ’은, 항균 및 탈취 기능을 제공하고, 압박 스타킹에서의 정전기 발생을 최소화하고, 사용자의 체온을 상승시키는 기능을 수행하도록 한 구리 나노 압박 스타킹을 제공하도록 한 것이다.And, the title of the invention of Korean Patent No. 10-2079587 'Copper Nano Compression Stockings' provides antibacterial and deodorizing functions, minimizes the generation of static electricity in the compression stockings, and serves to increase the user's body temperature. It is intended to provide a copper nano compression stocking.

그러나 상기한 종래의 의료용 압박스타킹 및 압박붕대는, 주로 탄성사 또는 코어방적사 등으로 편성하기 때문에, 장기간 착용 시에 원단의 늘어짐 현상 등이 나타나고, 편성사의 내구성이 현저히 떨어지는 문제점이 발생하였다.However, since the conventional medical compression stockings and compression bandages are mainly knitted with elastic or core spun yarns, sagging of the fabric occurs when worn for a long period of time, and the durability of the knitted yarn is significantly lowered.

또한, 신축성이 우수한 압박스타킹의 특성에 따라, 압박스타킹을 편성하는 편성사의 신장력 및 복원력을 향상시키고, 착용감 또한 향상시킬 수 있도록 하는 연구와 개발이 필요하게 되었다.In addition, according to the characteristics of the compression stockings with excellent elasticity, research and development were needed to improve the elongation and resilience of the knitting yarn for knitting the compression stockings, and to improve the fit.

상기한 문제점을 해결하기 위해 본 발명은, 스판덱스의 탄성사를 심사로 하고 나일론 DTY를 커버링사로 하여, 커버링사의 1차와 2차가 상호 역방향으로 권취되도록 편성사를 제조하기 때문에, 편성사의 신축성과 내구성이 향상되어, 편성사로 편성된 의료용 압박스타킹의 압박감과 착용감이 우수할 뿐만 아니라, 장기간 착용하여도 압박스타킹의 이완 현상 등을 차단하고 제품 사용수명을 최대화할 수 있도록 하는데 그 목적이 있는 것이다.In order to solve the above problems, the present invention uses the elastic yarn of spandex as the core and nylon DTY as the covering yarn to manufacture the knitted yarn so that the primary and the secondary of the covering yarn are wound in opposite directions to each other, so the elasticity and durability of the knitted yarn are improved. The purpose is to improve the feeling of pressure and fit of the medical compression stockings knitted with a knitted yarn, as well as to block the relaxation phenomenon of the compression stockings even when worn for a long time and to maximize the product lifespan.
