Abstract

A non-wooven fabric is manufactured by heat treatment of webs. The web consists of blended yarn and polyester yarn. The blended yarn consists of the core element made of resin having high melting-point, and the sheath element made of resin having low melting-point. The web is passed through a heating chamber in which carrier iron plates having a number of holes for passing hot air are placed to carry the web. The pressure of the bottom part of the chamber is lower than that of the upper one so as to induce the flow of the hot air, of which temperature is slightly higher than the melting point of the sheath resin. Thus the web is fused to form a lamina.

본 발명은 통상의 고융점섬유와, 저융점성분과 고융점성분을 복합시킨 복합섬유를 혼섬시킨 웹을 열풍처리하여서 숭고성이 좋으며 압축탄성회복율이 우수한 부직포의 제조방법에 관한 것이다.The present invention relates to a method for producing a nonwoven fabric having good sublime properties and excellent compression elastic recovery by hot air treatment of a mixture of ordinary high melting point fibers and composite fibers comprising a low melting point component and a high melting point component.

더욱 구체적으로 설명하면 본발명은 방식, 등받이 또는 요의 심재로 활용할 수 있는 부직포의 제조방법에 관한 것이다.More specifically, the present invention relates to a method for manufacturing a nonwoven fabric which can be utilized as a core material of a method, a backrest or a yaw.

종래의 부직포 제조방법은 접착제로 접착시키거나 저융점섬유로 융착시키는 방법의 어느것을 막론하고 배열된 섬유들이 당초의 배열 방향인 수평방향으로만 접착되어 있기 때문에 숭고성(崇高性)과 압축 탄성 회복율이 적으며 따라서 쿳숀성이 좋은 심재로 사용하기에는 부적합하였다.The conventional nonwoven fabric manufacturing method has high sublimability and compressive elasticity recovery rate because the fibers are bonded only in the horizontal direction, which is the original arrangement direction, regardless of whether they are bonded with an adhesive or fused with low melting fibers. It was small and therefore not suitable for use as a good core material.

본 발명은 이와같은 문제점을 해결한 것인바 이하 상세하게 설명하면 다음과 같다.The present invention is to solve the above problems will be described in detail below.

본 발명은 통상의 폴리에스텔 섬유와 시스-코어형(Sheath-Core) 복합섬유 (C)를 혼섬하여 웹을 만들었다.The present invention mixed the conventional polyester fiber and Sheath-Core composite fiber (C) to make a web.

위의 복합섬유는 저융점성분과 고융점성분으로된 시스-코어형인바, 시스부분은 저융점성분의 폴리에틸렌수지 성분이며 코어부분은 고융점성분의 폴리에스텔성분으로 되어있다.The composite fiber is a sheath-core type composed of a low melting point component and a high melting point component, the sheath portion is a polyethylene resin component of a low melting point component, and the core portion is a polyester component of a high melting point component.

통상의 폴리에스텔섬유 70-80중량부와 상기 복합섬유 30-20 중량부를 카딩하여 적절한 두께를 갖는 웹(W)을 만든다.70-80 parts by weight of conventional polyester fibers and 30-20 parts by weight of the composite fiber are carded to form a web W having an appropriate thickness.

이 웹 (W)을 밀폐된 열풍처리실 (1)에 통과시켜서 복합섬유의 저융점성분을 용융시키고 냉각공기로 냉각하여서 부직포를 제조한다.This web (W) is passed through a closed hot air treatment chamber (1) to melt the low melting point component of the composite fiber and cool it with cooling air to produce a nonwoven fabric.

이때 웹은 상, 하 2쌍의 테프론 코팅된 이송용 철판 사이에 물러서 열풍처리실을 통과하며 상, 하의 철판 (4)에는 다수의 구멍 (4a)이 천공되어 있다.At this time, the web retreats between the upper and lower pairs of Teflon-coated transfer iron plates and passes through the hot air treatment chamber, and the upper and lower iron plates 4 are perforated with a plurality of holes 4a.

본 발명에서 이송용 철판 (4)은 그 표면이 테프론 코팅되었으므로 웹이 철판에 달라붙지 않는다.In the present invention, the transfer sheet 4 has a Teflon coated surface, so that the web does not stick to the sheet.

열풍의 온도는 복합섬유의 폴리에틸렌성분을 용융시킬 수 있도록 140℃-170℃의 온도를 가지며 열풍은 순환펌프 (2)에 의하여 순환된다.The hot air has a temperature of 140 ° C.-170 ° C. to melt the polyethylene component of the composite fiber, and the hot air is circulated by the circulation pump 2.

열풍은 열풍처리실의 하부가 순환펌프에 의하여 저압(200mmAq 정도)이 되도록 하였으므로 열풍처리실의 상부로 유입된 열풍은 웹을 관통하여서 하부로 흐르고 순환펌프로 재순환된다.Since the hot air causes the lower part of the hot air treatment chamber to be low pressure (about 200 mmAq) by the circulation pump, the hot air flowing into the upper part of the hot air processing chamber flows through the web to the lower part and is recycled to the circulation pump.

열풍은 상부덕트내에 설치한 가열장치 (3)에 의하여 일정한 온도로 가열되도록 되어있다.The hot air is heated to a constant temperature by a heater 3 installed in the upper duct.

상, 하 칠판의 간격은 제조코저하는 부직포의 두께에 따라서 조절할 수 있으며 열풍처리실에서의 처리시간은 웹의 두께에 따라서 대개 3분-10분으로 조정한다.The spacing of the upper and lower boards can be adjusted according to the thickness of the nonwoven fabric to be manufactured. The treatment time in the hot air treatment chamber is usually adjusted to 3 to 10 minutes depending on the thickness of the web.

열풍처리실에서 융착처리된 웹은 열풍처리실을 나온 직후에 냉각공기로 냉각되고, 이어서 권치롤에 권치하든가 아니면 일정한 길이로 절단하여서 본 발명의 제조방법은 완성된다.The web fused in the hot air treatment chamber is cooled by cooling air immediately after leaving the hot air treatment chamber, and then wound on a winding roll or cut into a predetermined length to complete the manufacturing method of the present invention.

본 발명은 고온의 열풍이 웹을 관통하면서 열처리시키는 것이므로 관통되는 열풍의 흐름에 쫓아서 웹중의 일부 섬유는 웹의 수직방향으로 배열된다.In the present invention, the hot hot air is heat-treated while penetrating the web, so that some fibers in the web are arranged in the vertical direction of the web, in pursuit of the flow of the hot air.

이와같이 되면 수직방향으로 배열된 통상의 폴리에스텔 섬유와 복합섬유중 복합섬유의 시스성분이 용융하면서 인접한 섬유들을 응착시키고 용융되지 않은 복합섬유의 코어성분섬유와 통상의 폴리에스텔섬유는 웹의 수직방향으로 배열고정되기 때문에 이들은 부직포 내부에서 수직방향으로 작용하는 스프링의 역활을 수행하게 된다.In this case, the sheath component of the composite fiber of the normal polyester fiber and the composite fiber arranged in the vertical direction melts to adhere adjacent fibers, and the core component fiber and the normal polyester fiber of the unmelted composite fiber are in the vertical direction of the web. Because they are fixed, they act as springs acting vertically inside the nonwoven fabric.

그러므로 본 발명으로 제조된 부직포는 수직방향으로 다수 배열된 섬유들로 말미아마 숭고성이 좋으며 압축에 대한 탄성회복율이 매우 양호해진다.Therefore, the nonwoven fabric prepared according to the present invention has a good sublimation property with fibers arranged in a plurality of vertical directions, and the elastic recovery rate against compression becomes very good.
