Description

전자파 차폐시트용 직물의 정련방법{Scouring method of electromagnetic wave shielding fabric}TECHNICAL FIELD [0001] The present invention relates to an electromagnetic wave shielding fabric,

본 발명은 전자파 차폐시트용 직물의 정련방법에 관한 것으로, 특히 하이소프트 정련기 및 CPB(Cold Pad Batch)를 이용하여 직물의 정련이 효과적으로 이루어짐과 동시에 공정별 단축에 따른 비용절감으로써 전자파 차폐시트를 사용하기 위한 초세섬 직물의 잔지율을 최소화하면서도 두께가 일정하게 유지된 상태에서 효율적으로 정련할 수 있는 전자파 차폐시트용 직물의 정련방법을 제공하는 것이다.The present invention relates to a method for refining a fabric for an electromagnetic wave shielding sheet, and more particularly, to a method for refining a fabric using a high soft refining machine and a CPB (Cold Pad Batch), and at the same time, And to provide a method for refining a fabric for an electromagnetic wave shielding sheet capable of efficiently refining a state in which the thickness remains constant while minimizing the residual ratio of the ultra fine island fabric for use.

일반적으로 전자파 차폐시트는 노이즈 발생원과 피해 물체 사이의 전자파 경로에 위치되어 불필요한 전자파가 복사되어 전자기기 외부로 방출되는 것을 줄이거나 외부 전자파가 전자기기 내부로 침투되어 전자기적 결합을 형성하는 것을 방지하여 전자기기가 전자파 환경 내에서 적합하게 작동하여 전자기기의 동작 및 성능을 유지시킬 수 있는 시트이다.Generally, an electromagnetic wave shielding sheet is positioned in an electromagnetic wave path between a noise generating source and an object to prevent unnecessary electromagnetic radiation from being radiated to the outside of an electronic device, or to prevent electromagnetic waves from penetrating into an electronic device The sheet is a sheet which can operate properly in an electromagnetic environment to maintain the operation and performance of the electronic apparatus.

이러한 전자파차페시트의 주요 소재는 폴리에스테르로 사용되고 있다.The main material of such electromagnetic wave chafing sheet is used as polyester.

전자파차폐시트의 도금 공정과 전자파차폐시트의 최종 품질에 직접적인 영향을 주는 기재인 직물의 중요성에도 불구하고 직물의 정련과정은 정밀한 부품소재로서의 개념이 없이 생산되고 있으며 이와 더불어 휴대폰 및 LCD 판넬등에 내장되는 전자파 차폐시트는 상기와 같은 생산환경으로 인해 섬유기재 및 최종 제품의 정밀도 문제로 일본 등에서 수입에 의존해오고 있는 실정이다.Despite the importance of the fabric as a base material that directly affects the quality of the electromagnetic shielding sheet and the final quality of the electromagnetic shielding sheet, the refining process of the fabric is produced without any concept as a precise part material. In addition, BACKGROUND ART [0002] Electromagnetic wave shielding sheets have been dependent on imports in Japan and the like due to the problems of precision of fiber substrates and final products due to the above-described production environment.

최근에 와서 이러한 문제점을 인식하여 전자파차폐시트의 국내생산이 이루어지고 있지만 생산업체의 대부분이 의류용 직물 염색업체이며 염색전 전처리 개념으로 정련을 행하므로써 휴대폰, 모니터 등에 사용되는 초박막 전자파차단제에 요구되는 정밀한 순도 및 규격기준 성능을 만족하기 어려운 실정이다.In recent years, awareness of these problems has led to the domestic production of electromagnetic shielding sheets. However, most of the producers are textile fabric dyeing companies and refining them by pre-treatment concept before dyeing, which is required for ultra thin electromagnetic wave shielding It is difficult to satisfy the precision purity and the standard performance.

도 1은 본 발명에 의한 전자파 차폐시트용 직물의 정련방법을 나타내는 순서도로서, 본 발명에 따른 전자파 차폐시트용 직물의 정련방법은 도 1에 도시한 바와 같이 연폭단계(S100) - CPB정련단계(S200) - 숙성단계(S300) - 하이소프트정련단계(S400) - 하이소프트수세단계(S500) - 하이소프트산수세단계(S600) - 텐터가공단계(S700)가 순차적으로 이루어져 수행된다.FIG. 1 is a flow chart showing a method of refining a fabric for an electromagnetic wave shielding sheet according to the present invention, wherein the refining method of a fabric for an electromagnetic wave shielding sheet according to the present invention comprises the following steps of softening step S100 to CPB refining step S200 - Aging step S300 - High soft refining step S400 - High soft washing step S500 - High soft arithmetic three steps S600 - Tentering step S700 are sequentially performed.

연폭단계(S100)는 직물의 정련작업에 소요되는 길이 만큼의 원단을 재봉기로 연결하여 정련을 준비하는 단계이다.The softening step S100 is a step of preparing the refining by connecting the fabric as much as the length required for the refining operation of the fabric by a sewing machine.

상기 연폭단계(S100)에 사용되는 직물은 7 ~ 9denier로 이루어지는 폴리에스테르 원사를 이용한 평직 또는 리브 조직으로 제직되는 직물이 바람직하며, 이와 같은 직물의 조직은 도금의 평활성 확보 및 전자 기기의 차폐시트로 사용되기 위한 최적의 고밀도 조직 구성이 가능하기 때문이다.The fabric used in the softening step S100 is preferably a fabric woven in a plain or rib structure using a polyester yarn made of 7 to 9 denier. The fabric of such a fabric is used for securing the smoothness of the plating, It is possible to construct an optimal high-density structure to be used.

CPB정련단계(S200)는 연폭단계(S100)에서 정련을 하기위해 준비된 직물을 1차적으로 정련하기 단계로서, CPB정련단계(S200)에서 준비된 제1정련제를 콜드 패드 배치 처리조에 수용시키고 연폭단계(S100)를 거친 직물이 제1정련제가 수용된 콜드 패드 배치 감량기를 거쳐 정련되는 단계이다.The CPB refining step S200 is a step of primarily refining the fabric prepared for refining in the softening step S100. The first refining agent prepared in the CPB refining step S200 is accommodated in the cold pad arranging bath, S100) is refined through a cold pad placement reduction device containing the first scouring agent.

상기 제1정련제는 물 1L당 산화호발제 3 ~ 5g을 혼합한 용액, 물 1L당 정련제3 ~ 5g을 혼합한 용액, 물 1L당 가성소다(고상) 30 ~ 50g을 혼합한 용액, 물 1L당 소다회 5 ~ 7g을 혼합한 용액, 물 1L당 알카리침투제 3 ~ 5g을 혼합한 용액, 물 1L당 과산화수소수 7 ~ 9g을 혼합한 용액, 물 1L당 과수안정제 3 ~ 5g을 혼합한 용액, 물 1L당 유화분산제 3 ~ 5g을 혼합한 용액으로 이루어진다.The first scouring agent is a solution prepared by mixing 3 to 5 g of an oxidizing agent per 1 L of water, 3 to 5 g of a scouring agent per liter of water, 30 to 50 g of caustic soda (solid) per 1 L of water, A mixed solution of 5 to 7 g of soda ash, a mixed solution of 3 to 5 g of an alkali penetrant per 1 L of water, a mixed solution of 7 to 9 g of hydrogen peroxide per 1 L of water, a mixed solution of 3 to 5 g of a water stabilizer per 1 L of water, And 3 to 5 g of an emulsifying dispersant per molecule.

상기 제1정련제를 이루는 구성요소를 살펴보면,As for the components constituting the first scouring agent,

산화호발제는 제직공정에서 경사에 호부된 생지상의 호제를 제거하는 기능을 수행하도록 하며 직물의 기타 불순물도 동시에 제거하기 위해 정련제, 알칼리침투제, 유화분산제 등과 같이 제1정련제를 이루는 다른 구성요소와 같이 호제를 분해해 제거시키도록 한다.The oxidizing agent acts to remove the foaming agent on the slurry in the weaving process and to remove other impurities of the fabric at the same time as other components of the first scouring agent such as a scouring agent, Disassemble and remove the paste.

정련제는 직물을 제직하는 폴리에스테르원사의 제조공정의 오일과 호부공정의 각종 호제와 직물의 제직과정까지의 기타 불순물, 오염물질을 제거하도록 한다.The scouring agent is used to remove various impurities such as oils in the manufacturing process of the polyester yarn to weave the fabric and the weft process, and other impurities and pollutants until the weaving process of the fabric.

고상가성소다(수산화나트륨, Sodium hydroxide)는 조해성이 강한 반투명 고체로 물에 용해한 고상가성소다 용액은 제1정련제에서 강알카리 성질을 보완되도록 한다.The solid caustic soda (sodium hydroxide) is a semitransparent solid with a strong decomposition, so that the solid caustic soda solution dissolved in the water compensates the strong alkaline property in the first scouring agent.

소다회(탄산나트륨, Sodium carbonate)는 백색 분말로 이루어져 고상가성소다와 더불어 제1정련제에서 강알칼리 성질이 구비되도록 한다.Soda ash (sodium carbonate) is composed of white powder, solid caustic soda as well as strong alkaline properties in the first scouring agent.

알칼리침투제는 호발정련 효과를 높이기 위해 제1정련제의 섬유상 침투력을 높이는 계면활성제로 사용된다.The alkali penetrant is used as a surfactant to enhance the fibrous penetration of the first scouring agent to enhance the scouring effect.

과산화수소(Hydrogen Perdxide)는 섬유상 색소를 제거하여 직물의 표백효과를 도모하도록 한다.Hydrogen peroxide removes fibrous pigments to help bleach the fabric.

과수안정제는 상기 과산화수소가 용해된 제1정련제의 처리온도까지 승온관정에서 반응이 격하게 일어나는 현상을 안정적으로 조절하는 작용을 수행하도록 한다.The hydrous water stabilizer allows the hydrogen peroxide to stably control the reaction of the first scouring agent to the treatment temperature.

유화분산제는 제1정련제에 의해 탈락된 섬유상 불순물의 확산작용으로 재부착을 방지케 하는 계면활성제이다.The emulsifying dispersant is a surfactant that prevents re-adhesion due to the diffusion action of the fibrous impurities removed by the first scouring agent.

또한 여기서 제1정련제의 고상가성소다 및 소다회의 중량을 기타 다른 구성요서에 비해 높여주어 강알칼리성 성질이 극대화되어 호발정련 효과를 가지게 하며, 강알카리의 농도가 제1정련제의 고상가성소다 및 소다회의 중량보다 떨어지게 이루어지면 호발제 및 정련제의 활성이 불충분하게 되고 강알칼리의 농도가 제1정련제의 고상가성소다 및 소다회의 중량보다 초과되면 알칼리제는 물론 중화처리 경비가 과다 소요되어 생산단가를 높이는 단점이 있기 때문이다.In this case, the weight of solid caustic soda and soda ash of the first scouring agent is increased as compared with the other constituents, so that the strong alkaline property is maximized and the scouring effect is enhanced. When the concentration of the strong alkali is higher than the solid caustic soda of the first scouring agent and the soda ash If the weight of the first scouring agent is less than the weight, the activity of the scouring agent and the scouring agent becomes insufficient, and if the concentration of the strong alkali is higher than the weight of the solid caustic soda and the soda ash of the first scouring agent, Because.

그리고 상기 CPB정련단계(S200)에서 Cold Pad Patch 처리조에 수용된 제1정련제의 온도는 50℃로 유지되는 것이 바람직하며, 이와 더불어 직물의 처리속도는 분당(min) 20m로 이루어지는 것이 바람직하다.In the CPB refining step (S200), the temperature of the first scouring agent contained in the cold pad patch treatment tank is preferably maintained at 50 ° C., and the processing speed of the fabric is preferably 20 m per minute (min).

이는 제1정련제의 온도가 50℃ 미만으로 유지되면 제1정련제와 직물과의 반응이 불충분하기 때문이다.This is because the reaction of the first scouring agent with the fabric is insufficient if the temperature of the first scouring agent is maintained below 50 캜.

숙성단계(S300)는 상기 CPB정련단계(S200)를 거친 직물을 상온에서 숙성시켜 직물에 침투된 제1정련제가 효과적으로 반응하도록 하는 단계이며, 좀 더 상세하게는 CPB정련단계(S200)를 거친 직물을 회전 가능한 롤에 권취하여 직물이 권취된 상태에서 롤을 회전시켜 숙성하는 것이 바람직하다.The aging step S300 is a step of aging the fabric having undergone the CPB refining step S200 at room temperature so that the first refining agent penetrated into the fabric is effectively reacted. More specifically, Is wound around a rotatable roll, and the roll is rotated in a state in which the fabric is wound, and then aged.

이는 제1정련제가 침투된 상태의 직물이 롤에 권취된 상태로 유지되면 중력에 의해 직물에 침투된 제1정련제가 롤의 하부측에 위치한 직물 부위로 쏠리게 되어 권취된 직물의 상하간 불균일 반응을 방지하기 위함이다.This is because when the fabric in which the first scouring agent is impregnated is held in a state wound on the roll, the first scouring agent, which has been infiltrated into the fabric by gravity, is concentrated to the fabric positioned on the lower side of the roll, .

따라서 좀 더 상세하게는 CPB정련단계(S200)를 거친 직물을 롤에 의해 시간당 35 ~ 40회 정도 회전시켜주어 충분한 숙성과 직물에 전체적인 균일한 반응을 도모하도록 한다.More specifically, the fabric having undergone the CPB refining step (S200) is rotated by about 35 to about 40 times per hour by a roll so as to achieve sufficient aging and uniform overall reaction to the fabric.

하이소프트정련단계(S400)는 물 1L당 산호호발제 3 ~ 5g을 혼합한 용액, 물 1L당 정련제 3 ~ 5g을 혼합한 용액, 물 1L당 가성소다 30 ~ 50g을 혼합한 용액, 물 1L당 소다회 5 ~ 7g을 혼합한 용액, 물 1L당 알카리침투제 3 ~ 5g을 혼합한 용액, 물 1L당 유화분산제 3 ~ 5g을 혼합한 용액으로 이루어진 제2정련제를 준비한다.In the high soft refining step (S400), a solution obtained by mixing 3 to 5 g of coral reef preparation per 1 L of water, a solution of 3 to 5 g of refining agent per liter of water, a solution of 30 to 50 g of caustic soda per 1 L of water, A second scouring agent consisting of a solution obtained by mixing 5 to 7 g of soda ash, a solution obtained by mixing 3 to 5 g of an alkali penetrant per 1 L of water and a solution of 3 to 5 g of an emulsifying dispersant per liter of water is prepared.
