도 1에 도시된 바와 같이 본 발명의 부직포 제조방법은, 전처리 공정(S10)과, 혼타면 공정(S20)과, 혼합사 검사/제거 공정(S30)과, 웹 포밍 공정(S40)과, 소면 공정(S50)과, 스펀레이스 공정(S60)과, 건조 공정(S70) 및 부직포 검사 공정(S80)을 포함하여 이루어진다.As shown in FIG. 1, the nonwoven fabric manufacturing method of the present invention includes a pretreatment step (S10), a blend surface step (S20), a mixed yarn inspection / removal step (S30), a web forming step (S40), and a carding face. It includes a step (S50), a spunlace step (S60), a drying step (S70), and a nonwoven fabric inspection step (S80).

상기 전처리 공정(S10)은, 크게 세 가지로 분류된다. 첫째, 카딩(Carding) 단계(S11)로서, 공지된 카딩기를 이용하여 대나무 섬유용 펄프(Pulp)를 빗질하고 평행배열시키며 잡물(雜物)을 제거하는 단계이다. 둘째, 슬라이버(Sliver)를 제조하는 단계(S12)로서, 상기 카딩 단계에서 평행 배열된 대나무 섬유용 펄프를 연속적 끈 모양의 섬유 다발 형태로 제조하는 단계이다. 셋째, 개섬(Opening) 단계(S13)로서, 섬유 다발 형태의 대나무 섬유용 펄프를 찢고 두드리며 빗질하여 엉킨 것을 풀어 헤쳐 대나무 섬유용 펄프를 원재료로 한 원사(原絲)를 제조하는 단계이다.The pretreatment step (S10) is largely classified into three types. First, as a carding step (S11), combing and parallel arranging pulp for bamboo fiber using a known carding machine and removing miscellaneous matter. Secondly, as a step (S12) of manufacturing a sliver, a step of producing a continuous string-like fiber bundle of pulp for bamboo fibers arranged in parallel in the carding step. Third, in the opening step (S13), the bamboo fiber pulp in the form of fiber bundles is torn, pounded and combed to entangle and squeeze, thereby producing a yarn made of bamboo fiber pulp as a raw material.

이러한 상기 전처리 공정(S10)은 대나무 펄프에 잡물이 다량으로 함유된 것을 고려한 공정으로써 이 공정에서 상당량의 잡물이 제거되어 상기 혼타면 공정(S20)에 우수한 품질의 대나무 섬유용 펄프로 제작된 원사를 제공할 수 있게 된다.The pre-treatment step (S10) is a process considering that a large amount of miscellaneous material contained in the bamboo pulp, a considerable amount of miscellaneous material is removed in this process, and the yarn made of pulp for bamboo fiber of excellent quality in the mixed surface process (S20). It can be provided.

상기 혼타면 공정(S20)은, 상기 대나무 섬유용 펄프로 제작된 원사와, 이종(異種) 원사를 혼합하여 혼합사를 제조하는 공정이다. 여기서 상기 이종 원사는 폴리프로필렌, 폴리에틸렌, 폴리에스테르, 레이온 및 면(Cotton) 중 선택된 어느 하나인 것으로 선택적으로 사용 가능하다.The said blend surface process (S20) is a process of mixing the yarn manufactured with the said pulp for bamboo fiber, and a heterogeneous yarn, and manufacturing a mixed yarn. Here, the heterogeneous yarn may be selectively used as any one selected from polypropylene, polyethylene, polyester, rayon, and cotton.

다만, 본 발명은 기능성과 친환경성을 고려하여 상기 혼합사 100% 중량비 중에 상기 대나무 섬유용 펄프로 제작된 원사의 중량비를 적절히 조절할 필요가 있다. 만일, 상기 대나무 섬유용 펄프로 제작된 원사의 중량비가 40% 이하가 되면, 항균, 소취 및 소수성이 저하되어 제품 용도상 바람직하지 않으며, 상기 대나무 섬유용 펄프로 제작된 원사의 중량비가 60% 이상이 될 경우에는 보플이 발생하여 피부에 달라붙어 감촉이 나쁘게 됨은 물론이고 친수성이 증가되어 축축한 느낌을 갖게 된다는 점에서 이 또한 바람직하지 않으므로, 상기 혼합사 100% 중량비 중에 상기 대나무 섬유용 펄프로 제작된 원사의 중량비를 40% 내지 60% 가 되도록 적절히 조절함이 바람직하다.However, the present invention needs to properly adjust the weight ratio of the yarn made of the bamboo fiber pulp in the blended 100% weight ratio in consideration of functionality and environmental friendliness. If the weight ratio of the yarn made of the bamboo fiber pulp is 40% or less, the antibacterial, deodorant and hydrophobicity is lowered, which is not desirable in product use, and the weight ratio of the yarn made of the bamboo fiber pulp is 60% or more. In this case, the baffle is generated and sticks to the skin, thereby making the texture worse, as well as increasing the hydrophilicity to have a moist feeling. It is preferable to suitably adjust the weight ratio of yarn to 40% to 60%.

상기 혼합사 검사/제거 공정(S30)은, 공지된 원사오염검사기를 사용하여 상기 혼합사를 이송닥트로 연속적으로 날려 통과시키면서 잡물을 CCTV로 실시간 검사하며, 상기 CCTV에 의해 감지된 잡물을 고압의 에어로 외측으로 순간 이송 제거시키는 공정이다.In the mixed yarn inspection / removal process (S30), the mixed yarn is continuously blown through the transfer doc using a known yarn contamination tester, and real-time inspection of the miscellaneous goods by CCTV, and the high-pressure of the miscellaneous goods detected by the CCTV Instantaneous transfer removal to the outside of the air.

상기 웹 포밍 공정(S40)은, 상기 혼합사를 여려 겹 쌓아올려 다층의 시트로 형성시키는 공정이며, 상기 소면 공정(S50)은, 앞서 실시된 카딩 단계(S11)와 유사한 공정으로 상기 시트를 빗질하고 평행배열시키는 공정이다.The web forming step (S40) is a step of stacking the mixed yarns in multiple layers to form a multi-layered sheet, the carding step (S50), combing the sheet in a similar process to the carding step (S11) previously performed And parallel arrangement.

상기 스펀레이스 공정(S60)은, 상기 다층의 시트에 고압의 물을 분사시켜 서로 교락시킴으로써 부직포를 형성하는 공정으로, 물의 흐름으로 시트들을 서로 엉키도록 한 것이기 때문에 부드러운 감촉을 갖는 부직포를 형성시킬 수 있게 된다. 아울러 이 공정(S60)을 통하여 시트 상의 잡물들이 깨끗이 제거됨은 물론, 분진이 날릴 소지도 막을 수 있다는 이점이 있다.The spunlace step (S60) is a step of forming a nonwoven fabric by injecting high-pressure water to the multi-layered sheet and entangled with each other, so that the sheets are entangled with each other by the flow of water, thereby forming a nonwoven fabric having a soft feel. Will be. In addition, through this step (S60) there is an advantage that the miscellaneous goods on the sheet can be removed, as well as to prevent dust from flying.

다음으로, 상기 건조 공정(S70)은 공지된 건조기에 상기 부직포를 이송 통과시킴으로써 상기 부직포를 건조시키게 된다. Next, the drying step (S70) is to dry the nonwoven fabric by transferring the nonwoven fabric to a known dryer.

마지막으로, 상기 부직포 검사 공정(S80)은, 도 2에 도시된 바와 같이, 이송되는 부직포(N)의 겉면에 청색 라이트(B)를 조사하는 발광장치(110)와, 상기 청색 라이트(B)에 의해 반사되는 영상을 각각 받아들여 부직포(N) 상의 잡물을 선별하는 CCD카메라(120)를 포함하는 부직포 검사장치(100)를 통해 최종적으로 상기 부직포(N) 상의 잡물을 선별해 내게 된다.Finally, the nonwoven fabric inspection step (S80), as shown in FIG. 2, the light emitting device 110 for irradiating the blue light (B) to the outer surface of the non-woven fabric (N) to be transported, and the blue light (B) The non-woven fabric N is finally sorted through the nonwoven fabric inspection apparatus 100 that includes a CCD camera 120 that receives each image reflected by the non-woven fabric N and selects the goods on the nonwoven fabric N.

여기서 상기 발광장치(110)는 부직포(N) 상의 잡물이 갈색 계열이어서 종래의 부직포 검사장치의 백색 라이트로는 선별이 잘 안 되는 점에 착안하여 잡물의 갈색 계열과 보색관계인 청색 계열의 라이트(B)를 이용하여 갈색 계열의 잡물이 두드러지게 나타나게 함으로써 잡물의 선별이 용이하게 한 것이다.The light emitting device 110 is a light-based light blue (B) complementary to the brown-based light of the miscellaneous object of the brown light of the conventional non-woven fabric (N), the light of the conventional non-woven fabric inspection device is not screened with the attention to the point ) Makes the selection of brown matters easier by making brown miscellaneous goods stand out.

또한, 상기 발광장치(110)는 종래기술에서 언급한 바와 같이, 빛의 세기에 영향을 크게 받는 트렌스퍼 타입을 배제하고, 리플렉션 타입(Reflection Type)을 적용하여 상기 부직포(N)의 양면에 청색 라이트(B)를 반사시키듯 각각 조사함으로써 Φ0.5mm 이하의 미세한 잡물도 감지 가능하게 한 것이다.In addition, as mentioned in the related art, the light emitting device 110 excludes a transfer type that is greatly influenced by the intensity of light, and applies a reflection type to apply blue color to both surfaces of the nonwoven fabric N.
