종래의 가죽사는 천연가죽을 세폭으로 절개하여 사용하거나 박판으로 만들어 기존의 실 외면에 감아서 피복하는 방법으로 제조하였기 때문에 실의 단면을 원형으로 제조할 수 없어 사용중에 뒤틀림과 비꼬임이 일어나는 문제가 있고, 굵기가 균등하지 않아 의류, 가방, 신발을 비롯하여 인테리어 분야에 적용할 때 사용이 제한되어 부족함이 많은 불편이 있었다.Conventional leather yarns are manufactured by cutting natural leather into thin sections, or by laminating and coating them on the outer surface of existing yarns, so that the cross section of the yarns cannot be manufactured in a circular shape, causing distortion and twisting during use. In addition, since the thickness is not even, there are many inconveniences in that the use is limited when applied to the interior field including clothing, bags and shoes.
본 발명은 상기 불편을 해소하기 위하여 개발된 것이다.The present invention has been developed to solve the above inconvenience.

이와 같이 된 본 발명은 폐가죽을 활용하여 제조한 일정규격의 천연가죽분말을 수용성폴리우레탄접착제가 도포된 중심사 표면에 공급하고, 고압정전기를 발생시킴으로써, 플로킹 공법으로 천연가죽분말이 접착제에 충돌하는 힘으로 식모되어 접착되고, 실의 단면이 원형을 유지하도록 연마가공하여 실을 제조하였기 때문에 천연가죽분말이 견고하게 중심사 표면에 부착되어 내구성을 가지게 되며, 제조된 가죽사가 천연가죽과 같은 질감과 외관을 유지하면서 일반실과 같은 모양을 낼 수 있어 제직, 편직에 사용할 수 있을 뿐 아니라 신발, 가방, 인테리어분야에 다양하게 활용할 수 있는 이점이 있다.
또한, 본 발명은 천연가죽분말을 평균 입경 3 ~ 10미크론 되게 분말한 것을 준비하고, 중심사 표면에 수용성폴리우레탄접착제를 40 ~ 60㎛ 두께로 도포하여 플로킹룸에 공급하고, 플로킹룸 상부에서 플로킹룸 속으로 준비한 천연가죽분말을 공급하면서 20 ~ 30KV 고압정전기를 발생시킴으로써, 플로킹룸에 공급된 천연가죽분말이 정전기압을 받아 플로킹룸을 지나가는 중심사 표면에 도포한 접착제에 충돌하여 식모되게 부착되므로 식모공정이 종료된 다음 건조시키면, 천연가죽분말이 중심사 표면에 일체로 접착되어 내구성을 가지게 되고, 식모되지 않고 중심사 표면에 묻어 있는 상태로 남아 있는 천연가죽분말은 브러시롤러를 접촉시켜 떨어냄으로써, 중심사에서 분리시키고, 집진기로 회수하여 재사용을 할 수 있게 되며 천연가죽분말이 식모된 실의 표면을 샌드페이퍼에 접촉시켜서 천연가죽분말의 표면을 연마가공함으로써, 표면이 가지런하게 가공이 이루어지고, 실의 단면이 원형으로 되는 가죽사를 얻을 수 있게 된다.
따라서 본 발명의 제법으로 가죽사를 제조하면 내구성이 높고 천연가죽의 질감과 외모를 가지는 가죽사 제조가 용이하여 폐가죽의 활용률을 높일 수 있고, 대량생산으로 가죽사를 제조할 수 있으며, 가죽사의 단면이 원형으로 제조되므로 일반적인 실과 같이 제직에 사용할 수 있어 다양한 피혁지의 제조가 가능하게 되고, 신발, 가방, 인테리어에 패턴이 다양한 가죽사 제품을 공급할 수 있는 이점이 있다.
In the present invention as described above, by supplying a natural leather powder of a certain standard prepared by using the waste leather to the surface of the core yarn coated with a water-soluble polyurethane adhesive, by generating a high-pressure electrostatic, the natural leather powder collides with the adhesive by the flocking method Since the thread is manufactured by bonding with the force and grinding the cross section of the thread to maintain the circular shape, the natural leather powder is firmly attached to the surface of the core yarn and has durability. It can be used for weaving and knitting, while maintaining its appearance, and can be used for weaving and knitting.
In addition, the present invention is to prepare a powder of natural leather powder with an average particle diameter of 3 ~ 10 microns, and to apply a water-soluble polyurethane adhesive 40 to 60㎛ thickness on the surface of the core yarn to supply to the flocking room, flocking on the top of the flocking room By supplying 20 ~ 30KV high voltage static electricity while supplying the natural leather powder into the room, the natural leather powder supplied to the flocking room receives the electrostatic pressure and collides with the adhesive applied on the surface of the core yarn passing through the flocking room. When the hair-drying process is finished and dried, the natural leather powder is integrally adhered to the surface of the core yarn to have durability, and the natural leather powder which is not planted and remains on the surface of the core yarn is brought into contact with the brush roller. Can be separated from the main thread, collected with a dust collector, and reused. Is brought into contact with the surface to sandpaper the surface of the natural leather, by processing the abrasive powder, it is justified that the surface processing is done, the cross-sectional area of the chamber it is possible to obtain a leather which is used in a circular shape.
Therefore, if the leather yarn is manufactured by the manufacturing method of the present invention, leather yarn having high durability and texture and appearance of natural leather can be easily manufactured to increase utilization of waste leather, and leather yarn can be manufactured by mass production. Since the cross section is manufactured in a circular shape, it can be used for weaving like a general thread, and thus, it is possible to manufacture a variety of leather papers, and there is an advantage of supplying a variety of leather products in patterns to shoes, bags, and interiors.
