활성탄소섬유(Activated Carbon Fiber)로 이루어진 원단(이하 "활성탄소섬유 원단"이라고 한다)은 다공성 고흡착 소재로서 대기정화 및 수소저장용 소재로 널리 사용되고 있다.BACKGROUND OF THE INVENTION Fabrics made of activated carbon fibers (hereinafter referred to as "activated carbon fiber fabrics") are widely used as atmospheric purification and hydrogen storage materials as porous highly adsorbed materials.

활성탄소섬유 원단을 제조하는 종래방법에서는 상기 활성탄소섬유 원단용 전구체 원단(이하 "전구체 원단"이라고 약칭한다)으로써, 활성탄소섬유용 전구체 단섬유(Staple)들이 서로 교락되어 있는 부직포 타입의 전구체 원단을 사용하여 이를 내염화처리, 저온 탄화처리 및 고온 활성화 처리하여 활성탄소섬유 원단을 제조하였으나, 부직포 타입의 전구체 원단을 구성하는 활성탄소섬유용 전구체 단섬유(Staple)의 중간부와 양측 말단부의 결정성 차이로 인해 저온 탄화 및 고온 활성화 처리시 상기 활성탄소섬유용 전구체 단섬유(Staple)의 중간부에서 활성화되는 정도와 상기 활성탄소섬유용 전구체 단섬유(Staple)의 양측 말단부에서 활성화되는 정도가 서로 상이하여 불균일한 활성화가 일어나며, 이로 인해 제조되는 활성탄소섬유 원단은 강도 및 비표면적 등의 물성이 불균일하게 되는 문제가 발생 되었다.In the conventional method for producing an activated carbon fiber fabric, a nonwoven fabric type precursor fabric (hereinafter referred to as "precursor fabric") in which activated carbon fiber precursor staple fibers are entangled with each other is used as the activated carbon fiber fabric precursor fabric Carbon fiber fabrics were prepared by chlorination treatment, low-temperature carbonization treatment and high-temperature activation treatment.

이와 같은 과제를 달성하기 위해서, 본 발명은 활성탄소섬유용 전구체 필라멘트를 제직 또는 편직하여 활성탄소섬유용 원단용 전구체 원단을 제조할 때 북(Shuttle) 직기,위편기, 경편기 또는 환편기를 사용하여 전구체 원단의 폭방향 양측 말단부에 위치하는 활성탄소섬유용 전구체 필라멘트를 절단하지 않고 접혀지게 한다.

Figure 2 is a schematic diagram of a precursor fabric of the present invention having both ends folded.

이하, 첨부한 도면 등을 통하여 본 발명을 상세하게 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명에 따른 활성탄소섬유 원단용 전구체 원단(이하 "전구체 원단"이라고 약칭한다)은 도 2에 도시된 바와 같이 활성탄소섬유용 전구체 필라멘트(20,30)들로 구성되며, 전구체 원단(10)의 폭방향 양측말단부(50)에서 활성탄소섬유용 전구체 필라멘트(30)가 절단되지 않고 접혀 있는 것을 특징으로 한다.The precursor fabric (hereinafter abbreviated as "precursor fabric") according to the present invention comprises precursor filaments 20 and 30 for activated carbon fibers as shown in FIG. 2, The precursor filaments 30 for active carbon fibers are folded without being cut at the widthwise end portions 50 in the width direction.

도 1은 본 발명에 따른 전구체 원단(10)의 모식도이다.1 is a schematic diagram of a precursor fabric 10 according to the present invention.

상기 활성탄소섬유용 전구체 필라멘트(20,30)은 폴리아크릴로니트릴계 필라멘트, 폴리비닐알콜계 필라멘트, 피치(pitch)계 필라멘트 또는 활성탄소섬유용 페놀계 전구체 섬유 등이다.The precursor filaments 20 and 30 for the activated carbon fibers are polyacrylonitrile filaments, polyvinyl alcohol filaments, pitch filaments, or phenolic precursor fibers for activated carbon fibers.

상기 전구체 원단은 직물, 경편물, 환편물 또는 위편물인 것이 바람직하고, 중량은 100~500g/㎡인 것이 바람직하다.Preferably, the precursor fabric is a fabric, a lightly knitted fabric, a circular knitted fabric or a woven fabric, and the weight is preferably 100 to 500 g / m 2.

상기 전구체 원단(10)의 중량이 100g/㎡ 미만인 경우에는 생산수율이 떨어지고, 500g/㎡을 초과하는 경우에는 열처리시 열풍이 전구체 원단(10)을 원활하게 통과하지 못해 표면과 이면 간의 활성화 차이가 발생되어 바람직하지 못하다.When the weight of the precursor body 10 is less than 100 g / m 2, the production yield is lowered. When the weight of the precursor body 10 exceeds 500 g / m 2, hot air does not smoothly pass through the precursor fabric 10 during heat treatment, Which is undesirable.

본 발명에 따른 상기 전구체 원단(10)을 차례로 내염화 처리, 200~350℃의 온도에서 저온 탄화처리 및 600~1,100℃의 온도에서 고온 활성화 처리하여 다공고흡착 소재로 유용한 활성탄소섬유 원단이 제조된다.The precursor body 10 according to the present invention is subjected to an oxidation treatment, a low-temperature carbonization treatment at a temperature of 200 to 350 ° C and a high-temperature activation treatment at a temperature of 600 to 1,100 ° C to produce an activated carbon fiber fabric useful as a porous adsorbent material do.

본 발명의 상기 전구체 원단(10)은 활성탄소섬유용 전구체 필라멘트(20)의 폭방향 양측 말단부 등에 의해 절단되지 않기 때문에 결정성 및 장력 변화가 일어나지 않는다. 그로 인해 상기 전구체 원단(10)의 폭방향을 기준으로 전구체 원단(10) 중앙부에 위치하는 활성탄소섬유 전구체 필라멘트(20) 부분과 원단의 양측 말단부(40)에 위치하는 활성탄소섬유 전구체 필라멘트 부분은 서로 균일한 결정성 및 장력을 구비한다.Since the precursor fabric 10 of the present invention is not cut by the both ends of the precursor filament 20 in the width direction of the activated carbon fiber, crystallinity and tensile force do not change. Whereby the activated carbon fiber precursor filament portion located at the center of the precursor fabric 10 and the activated carbon fiber precursor filament portion located at the opposite end portions 40 of the fabric are positioned with respect to the width direction of the precursor fabric 10 And have uniform crystallinity and tensile strength.

이로 인해, 본 발명에 따른 전구체 원단(10)을 내염화 처리, 저온 탄화처리 및 고온 활성화 처리하여 활성탄소섬유 원단을 제조하게 되면 전구체 원단(10) 전폭에 걸쳐 활성화가 균일하게 일어나 제조되는 활성탄소섬유 원단은 강도 및 비표면적 등과 같은 물성이 균일하게 된다.Accordingly, when the activated carbon fiber fabric is produced by the chlorination treatment, the low-temperature carbonization treatment, and the high-temperature activation treatment of the precursor fabric 10 according to the present invention, activation is uniformly performed over the entire width of the precursor fabric 10, The fiber fabric has uniform physical properties such as strength and specific surface area.

본 발명에 따른 상기 전구체 원단(10)은 북(Shuttle) 직기, 위편기, 환편기 또는 경편기를 사용하여 활성탄소섬유용 전구체 필라멘트로 제직 또는 제편한다.The precursor fabric 10 according to the present invention is woven or formed into precursor filaments for activated carbon fibers using a shuttle loom, a weft knitting machine, a circular knitting machine or a warp knitting machine.

그러나, 종래 워터제트(Water jet 직기, 에어제트(Air jet) 직기 또는 레피어 직기를 사용하여 활성탄소섬유용 전구체 필라멘트로 전구체 원단(10)을 제조하는 경우에는 도 1에 도시된 바와 같이 활성탄소섬유용 전구체 필라멘트(20)의 양측 말단부(40)가 절단되어 본 발명에 따른 전구체 원단을 제조할 수 없게 된다.However, when the precursor fabric 10 is produced from precursor filaments for activated carbon fibers using a water jet loom, an air jet loom, or a looper loom, The both end portions 40 of the precursor filament 20 for a fiber are cut off and the precursor fabric according to the present invention can not be produced.

이하, 실시예 및 비교실시예를 통하여 본 발명을 구체적으로 살펴본다.Hereinafter, the present invention will be described in detail with reference to examples and comparative examples.

그러나 하기 실시예는 본 발명의 구현일례일 뿐 본 발명의 보호범위를 한정하는 것은 아니다.However, the following examples are only illustrative of the present invention and do not limit the scope of protection of the present invention.
