It relates to a method for manufacturing a raw nonwoven fabric by a batch process including a spunlace method.
부직포(Non-woven fabric)란, 기계 조작에 의하거나 열접착 혹은 화학 약품을 사용하여 섬유를 접착시키거나 엉키게 하여 만든 직물을 가리킨다.Non-woven fabric refers to a fabric made by bonding or tangling fibers by mechanical operation, heat bonding or using chemicals.
직물로 하는 과정에서 실의 단계를 거치지 않는 것으로 펠트, 수지접착의 부직포, 니들 펀치, 스펀본드, 스펀 레이스, 엠보스 필름, 습식(濕式) 부직포 등이 있다.There are felt, non-woven fabric with resin adhesion, needle punch, spun bond, spun lace, embossed film, and wet non-woven fabric, which do not go through the step of yarn in the process of making a fabric.
이러한 부직포는 1950년경부터 미국에서 급속도로 발전하였는데, 섬유가 얽혀 있어서 종횡의 방향성이 없으며 자른 가장자리가 풀리는 일도 없기 때문에 여러 가지 용도에 쓰이고 있으며, 근래에는 의료용 위생용품, 생활위생용품, 기타 산업용 원료 등에서 널리 쓰이고 있다.These non-woven fabrics have developed rapidly in the United States since around 1950, and are used for various purposes because fibers are entangled and there is no vertical and horizontal direction, and the cut edges are not unwound. Recently, they are used in medical hygiene products, life hygiene products, and other industrial raw materials. It is widely used.
아래 표는 종래의 부직포 제조방법을 분류한 것이다.The table below categorizes the conventional nonwoven fabric manufacturing methods.

이와 같이 본 발명은 전 공정이 일괄공정으로 이루어짐으로써, 제조비용을 절감할 수 있으며 제조설비가 차지하는 면적을 줄일 수 있게 되는 장점이 있다.As described above, according to the present invention, since the entire process is performed as a batch process, there is an advantage in that the manufacturing cost can be reduced and the area occupied by the manufacturing equipment can be reduced.
원면 포장을 해체하는 단계(bales plucking)(S1)는, 원면(raw cotton)을 강한 압력으로 뭉쳐 놓은 포장 단위인 베일(bale)의 포장을 둥치풀기기(bale plucker)를 이용하여 해체하기 위한 단계이다.The bales plucking (S1) is a step for disassembling the bale, which is a packaging unit in which raw cotton is held together under strong pressure, using a bale plucker. to be.
원면을 펴는 단계(opening)(S2)는, 단단하게 뭉쳐진 원면을 부풀려서 펴기 위한 단계이다.The step of unfolding the raw surface (S2) is a step for inflating and unfolding the solidly united raw surface.
제1소면 단계(carding)(S3)는, 원면을 펴는 단계(S2)에서 펴진 원면을 소면기(card)를 이용하여 섬유에 붙어 있는 이물질이나 짧은 섬유를 걸러내고 머리를 빗듯이 섬유를 가지런하게 간추려 부직포 생산 규격에 맞게 일정한 폭, 두께 및 중량으로 균일화 시키는 단계이다.In the first carding step (S3), use a card to filter out foreign substances or short fibers attached to the fibers by using a card on the raw cotton unfolded in the step of unfolding the raw cotton (S2), and arrange the fibers as if combing the hair. This is the step of uniformizing the width, thickness, and weight according to the nonwoven production standard.
원면은 전술한 원면을 펴는 단계(opening)(S2)에 의하여 어느 정도까지는 풀어헤쳐지나, 섬유 이외의 잡물이 아직 많이 섞여 있고, 또 솜은 작은 덩어리로 뭉쳐 있으므로 이것을 완전히 헤쳐서 이물질이나 아주 짧은 섬유를 제거하고 섬유를 한 가닥씩 분리하여 가지런히 평행이 되게 하고, 이것을 모아서 슬라이버(sliver)로 만드는 공정이 필요하다.The raw cotton is loosened to some extent by the above-described opening (S2), but there are still a lot of miscellaneous matters other than fibers, and the cotton is clumped into small lumps. It is necessary to remove the fibers, separate the fibers one by one, make them neatly parallel, and collect them to form a sliver.
이러한 공정을 소면공정이라 하고, 소면공정에 쓰이는 기계를 소면기 또는 카드(card)라 한다.This process is called the carding process, and the machine used in the carding process is called a carding machine or card.
종래에는 못이 박힌 2장의 널빤지를 가지고 섬유덩어리를 처리하는 핸드카드가 이용되었다.Conventionally, a hand card has been used that handles fiber lumps with two nailed planks.
이것을 기계화하기 위하여 길이 약 1m, 지름 약 1m의 원통과 4∼8개의 원통(지름 10cm)을 결합하고, 이들 원통 표면에는 모두 가는 철사를 브러시 모양으로 박아 놓은 것이 오늘날 사용되고 있는 소면기의 원형이다. To mechanize this, a cylinder with a length of about 1 m and a diameter of about 1 m and 4 to 8 cylinders (diameter of 10 cm) are combined, and the surface of these cylinders are all brushed with thin wire, which is the prototype of the carding machine used today.
불순물 제거 및 원면을 고르는 단계(collecting)(S4)는, 제1소면 단계(S3)를 거친 원면에 포함된 불순물을 제거하고 섬유장 길이에 맞게 원면을 고르는 단계이다.In the step of removing impurities and selecting the raw cotton (S4), the impurities contained in the raw cotton that has been subjected to the first carding step (S3) are removed and the raw cotton is selected according to the length of the fiber length.
제2소면 단계(carding)(S5)는, 불순물 제거 및 원면을 고르는 단계(S4)를 거친 원면을 소면기(card)를 이용하여 작업에 용이하게 일정한 규격으로 균일화시키는 단계이다.The second carding step (S5) is a step of uniformizing the raw cotton that has undergone the step of removing impurities and selecting the raw cotton (S4) to a uniform standard for easy operation using a card.
원면을 교차 적층하는 단계(crosslapping)(S6)는, 부직포의 장력을 증대시키기 위해 제2소면 단계(S5)를 거친 복수의 원면을 교차로 적층하는 단계이다. The crosslapping (S6) of the raw surfaces is a step of alternately stacking a plurality of raw surfaces that have undergone the second cardinal step (S5) in order to increase the tension of the nonwoven fabric.
원면을 팽팽하게 당기는 단계(drafting)(S7)는, 상기와 같이 교차로 적층된 원면을 팽팽하게 당기는 단계이다.The step (drafting) (S7) of pulling the raw surface tightly is a step of pulling the cross-stacked raw surface tightly as described above.
제3소면 단계(carding)(S8)는, 부직포가 원하는 규격의 사이즈가 되도록 소면기(card)를 이용하여 원면의 사이즈를 늘리는 단계이다.The third carding step (S8) is a step of increasing the size of the raw cotton using a card so that the nonwoven fabric has a size of a desired standard.
이처럼 소면 공정을 제1소면 단계(S3), 제2소면 단계(S5) 및 제3소면 단계(S8)의 3단계로 구성한 이유는, 원면을 펴는 단계(opening)(S2)를 거친 원면이 균일한 분포로 형성되도록 하기 위함이다.The reason why the carding process is composed of three steps: the first carding step (S3), the second carding step (S5) and the third carding step (S8) is that the raw surface that has gone through the opening (S2) step is uniform. It is to be formed in one distribution.
섬유를 결속시키는 단계(spunlacing)(S10)는, 제3소면 단계(S8)를 거친 원면에 물을 고압으로 분사한 다음 원면이 롤러를 통과하도록 하여 섬유를 압착 결속시키는 단계이다.The spunlacing (S10) of the fibers is a step in which water is sprayed at high pressure on the raw cotton that has been subjected to the third carding step (S8), and then the raw cotton passes through a roller to compress and bind the fibers.
이때, 원면에 분사되는 물은 미세한 노즐을 이용하여 고압으로 분사되도록 하고, 물은 다단계로 정수처리된 정제수를 이용하는 것이 바람직하다.At this time, it is preferable to spray the water sprayed on the raw surface at high pressure using a fine nozzle, and use purified water treated in multiple stages for the water.
이처럼 합성수지나 접착제를 사용하지 않고 고압력의 물을 분사하여 섬유를 결속시킴으로써, 친환경적이고 안전성을 보장할 수 있게 된다.In this way, without using synthetic resins or adhesives, high pressure water is sprayed to bind the fibers, thereby ensuring environment-friendly and safety.
젖은 상태의 부직포를 롤에 감는 단계(wet winding)(S11)는, 섬유를 결속시키는 단계(S10)를 거치면서 젖은 상태로 된 부직포를 롤에 감는 단계이다.The step of winding the wet nonwoven fabric onto the roll (S11) is a step of winding the wet nonwoven fabric onto the roll while going through the step (S10) of binding the fibers.
표백 단계(bleaching)(S12)는, 고온의 스팀을 이용하여 부직포에 잔류하는 유분 및 기타 불순물을 제거하고 소독하는 단계이다.The bleaching step (S12) is a step of removing and disinfecting oil and other impurities remaining in the nonwoven fabric using high-temperature steam.
건조 단계(drying)(S13)는, 표백 단계(S12)를 거친 부직포를 건조시키는 단계이다.The drying step (S13) is a step of drying the nonwoven fabric that has undergone the bleaching step (S12).
이와 같이 섬유를 결속시키는 단계(S10) 이후에 표백 처리를 수행하는 표백 단계(bleaching)(S12)를 거친 다음 건조하는 단계(drying)(S13)를 수행함으로써, 원면의 섬유장이 손실되어 품질이 저하되는 것을 방지할 수 있게 된다.In this way, after the step of binding the fibers (S10), the bleaching step (S12) of performing a bleaching treatment is performed, and then a step of drying (S13) is performed, thereby reducing the quality due to loss of the fiber length of the raw cotton. It can be prevented from becoming.
재단하는 단계(slitting)(S15)는, 건조 단계(S13)에서 건조된 부직포를 제품 사이즈에 맞게 재단하는 단계이다.The slitting (S15) is a step of cutting the nonwoven fabric dried in the drying step (S13) according to the product size.
포장 단계(packaging)(S16)는, 상기 재단하는 단계(S15)에서 재단된 부직포를 포장하는 단계이다.The packaging step (S16) is a step of packaging the nonwoven fabric cut in the cutting step (S15).
이때, 제3소면 단계(S8) 후 섬유를 결속시키는 단계(S10) 이전에 물을 다단계로 정수하는 정수처리단계(filtering)(S9)를 더 포함할 수 있는데, 이러한 정수처리단계(S9)에 대해서는 도 3을 참조로 후술하기로 한다.At this time, it may further include a water purification step (filtering) (S9) of purifying water in multiple stages before the step (S10) of binding the fibers after the third carding step (S8). This water treatment step (S9) This will be described later with reference to FIG. 3.
또한, 건조 단계(S13) 후 재단하는 단계(S15) 이전에 부직포에 기능성 용액을 분사하여 부직포가 신선도를 유지하고 항균작용을 하도록 하는 기능성 용액 처리단계(S14)를 더 포함할 수 있다.In addition, after the drying step (S13) and before the cutting step (S15), a functional solution treatment step (S14) in which the nonwoven fabric maintains freshness and has an antibacterial action by spraying a functional solution onto the nonwoven fabric may be further included.
도 3은 본 발명에 따른 스펀레이스 공법을 포함하는 일괄공정에 의한 원면 부직포 제조방법에서 정수처리단계를 나타낸 도면이다.3 is a view showing a water treatment step in a method for manufacturing a raw nonwoven fabric by a batch process including a spunlace method according to the present invention.
정수처리단계(S9)는, 공기 부상형 필터(air floatation filter)를 이용한 1차 필터링 단계(S91)와, 모래 필터(sand filter)를 이용한 2차 필터링 단계(S92)와, 백 필터(bag filter)를 이용한 3차 필터링 단계(S93)를 포함한다.The water treatment step (S9) includes a first filtering step (S91) using an air floatation filter, a second filtering step (S92) using a sand filter, and a bag filter. ) And a third-order filtering step (S93).
이때, 섬유를 결속시키는 단계(S10)에서 사용된 물을 다시 공기 부상형 필터, 모래 필터 및 백 필터로 보내 정화한 다음, 섬유를 결속시키는 단계(S10)에서 재사용하도록 이루어진다.At this time, the water used in the step (S10) of binding the fibers is sent back to the air floating filter, the sand filter, and the bag filter for purification, and then reused in the step (S10) of binding the fibers.
이와 같이 본 발명은 다단계로 이루어진 정수처리단계(S9)를 공정에 추가함으로써, 물을 재사용할 수 있어 경제적·환경적으로 유리한 장점이 있다.As described above, the present invention has an economical and environmentally advantageous advantage because water can be reused by adding a water treatment step (S9) consisting of multiple steps to the process.
