Description

워터제트(WATER JET)직기의 공정지(FALSE STOP) 방지방법 및 그 조성물Method for preventing FALSE STOP of water jet loom and composition

본 발명은 워터제트직기의 제직시에 발생하는 공정지(空停止)를 방지하는 방법 및 그 조성물에 관한 것이다. 좀더 상세하게는 제직시 위사의 착오 감지여부가 원인이 되어 발생하는 직기의 공정지 또는 공제직(空製織)을 방지하기 위한 방법 및 조성물에 관한 것이다.TECHNICAL FIELD This invention relates to the method of preventing the process paper which arises at the time of weaving a waterjet loom, and its composition. More specifically, the present invention relates to a method and a composition for preventing a process paper or a deduction of weaving looms caused by the detection of aberrations of weft during weaving.

통상의 제트직기에 있어서는, 제직시 위사를 탐지하는 장치인 휠러휭거(feeler finger)가 있어서 위사가 정상적으로 캣취코드사(catch cord yarn)에 도착했을 때에 베틀바듸(reed)는 이 위사를 상기 휠러휭거에 접촉시키게 되고, 센서는 포지션센서(position sensor) 구간에서 휠러휭거(이하 "휭거"라 칭함)의 고전압휭거와 저전압휭거에 실이 닿을 때 흐르는 미세한 전류를 검출하여 실의 유무를 판별하게 되는데, 이때 위사에 부착된 물이 전도체로 작용함으로써 고전압(HP) 휭거와 저전압(LP)휭거 사이에 전기를 통전시켜 위사의 위입상태를 감지하게 되는 것이다. 따라서, 제직시 위사는 친수성(親水性)으로 물에 잘 젖어야 하고 그 묻어 있는 물이 전기를 잘 통해주어야 하는 것을 전제로 한다. 그러므로, 워터제트직기에 있어서, 노즐에서 분사되는 물은 전도율이 25℃에서 140~350μΩ/cm 이상이고 경도가 3.0ppm이하, 탁도가 2.0ppm이하, pH6.0~7.5 증발잔유를 100ppm 이하의 정수가 사용되고 있다. 한편 실의 형태나 물성등도 통전성에 영향을 미치는데, 태본 수화섬사, 세본수화섬사, 강연화섬사(强撚化纖絲) 등 고급직물용 원사의 경우는 구조적으로 평활성 부족, 유연성 부족, 균제도 불량, 장력불균형, 연사각도의 불균일 등의 결점을 갖고 있어서 이러한 여러 요인들이 위사와 휭거면과의 접촉량을 감소시키고, 이것이 공정지 발생의 원인이 되기도 한다. 따라서, 통상 직조시에는 원사에 유연성 및 평활성을 부여하기 위해 유연제나 급유제등을 사용하기도 하는데 이러한 오일링(oiling)제의 사용은 오히려 원사의 친수성(親水性)을 감소시켜 위사의 통전성에 악영향을 미친다.In a conventional jet loom, there is a wheeler finger which is a device for detecting the weft yarn during weaving, and when the weft yarn arrives at the catch cord yarn normally, the reed turns the weft yarn into the weft yarn. The sensor detects the presence of the thread by detecting the minute current flowing when the thread touches the high voltage and low voltage of the wheeler finger (hereinafter referred to as "the finger") in the position sensor section. At this time, the water attached to the weft acts as a conductor to detect electricity entering the weft state by energizing electricity between high voltage (HP) and low voltage (LP) removal. Therefore, when weaving, it is assumed that the weft is hydrophilic (으로 水性), soaked well in water, and the buried water should be well supplied with electricity. Therefore, in the water jet loom, the water sprayed from the nozzle has an electrical conductivity of 140 to 350 µΩ / cm or more at 25 ° C, hardness of 3.0 ppm or less, turbidity of 2.0 ppm or less, and pH 6.0 to 7.5 evaporation residues of 100 ppm or less. Is being used. On the other hand, the shape and the physical properties of the yarn also affect the electrical conduction.For high-quality fabric yarns such as taebon hydration thread, sebon hydration thread, and gyrosized thread yarn, structural weakness, lack of flexibility, poor leveling, Due to the drawbacks of tension imbalance and non-uniformity of twist angle, these factors reduce the amount of contact between the weft and the weft surface, which may cause the process paper. Therefore, in the case of weaving, softeners or lubricating agents are sometimes used to give the yarns flexibility and smoothness. However, the use of oiling agents reduces the hydrophilicity of the yarns and thus adversely affects the flowability of the weft yarns. Crazy

이와 같이 위사의 전류흐름에 장애가 생기면 위사가 제대로 위입되어 휠러휭거에 도착하였는데도 센서는 실이 없음을 착오로 검출할 수 있어서 불필요하게 직기를 정지시키는 경우가 발생한다. 이와 같은 직기의 공정지는 가동율 및 직물의 품질 특히, 고급직물의 품위를 저하(스톱마트 발생)시켜 생산성 향상에 커다란 장애요인이 된다.In this way, if the current flow of the weft is disturbed, the weft is properly infiltrated and arrived in the wheeler funger, but the sensor can detect the absence of a thread by mistake, so that the loom stops unnecessarily. The processing paper of such looms is a major obstacle to improving productivity by lowering the utilization rate and the quality of the fabric, in particular, the quality of high-quality fabrics (stop mart).

지금까지 개발된 가장 효과적인 공정지 방지기술은 휠러 대신에 적외선 센서에 의해 위사의 유무를 탐지하는 무저항, 무접촉에 의한 공정지 방지장치(상품명 : IR-FEELER), 제트기연)이다. 이 장치는 위사와의 접촉없이도 감지가 가능하므로 분사되는 물의 수량, 수압, 분사방향등에 영향을 받지 아니하며 따라서, 제직 조건을 조정하기위해 고기능을 필요로 하지 않는다. 반면, 제직하고자 하는 직물의 폭이 다양할 경우 각 직물의 폭에 맞추어 상이한 바듸를 설치해야 하므로 이를 교환하는 번거로움과 추가비용이 소요된다.The most effective process paper prevention technology developed so far is a non-resistance, contactless process paper prevention device (trade name: IR-FEELER), jet smoke, which detects the presence or absence of the weft by an infrared sensor instead of the wheeler. The device can be detected without contact with the weft, so it is not influenced by the quantity of water sprayed, water pressure, spraying direction, etc. Therefore, it does not need high function to adjust the weaving condition. On the other hand, if the width of the fabric to be weaved is different, it is necessary to install a different change in accordance with the width of each fabric, it takes the hassle and additional cost of exchange.

본 발명자는 위와 같은 워터제트직기의 제직시의 문제점을 예의 검토한 결과, 상기한 바와 같이, 통전성 불량의 근본원인이 물에 있음을 확인하고 위사의 친수성과 물의 전도성을 높여주어 워터제트직기의 직조시 공정지를 방지할 수 있는 신규한 조성물을 개발함으로써 본 발명을 완성하기에 이르렀다.As a result of thorough examination of the problems of weaving of the water jet loom as described above, the inventors have confirmed that the root cause of the poor electrical conductivity is in the water and improves the hydrophilicity and water conductivity of the weft of the water jet loom as described above. The present invention has been completed by developing a novel composition capable of preventing process paper.

본 발명의 목적은 워터제트직기의 공정지를 방지할 수 있는 직조방법을 제공함에 있다. 본 발명의 또 다른 목적은 신규의 공정지 방지 조성물을 제공함에 있다. 본 발명은 원사를 전기전도성 무기염의 수용액 조성물로 처리하여 직조함으로써 달성된다. 본 발명의 공정지 방지 조성물은 물에 잘 녹는 무기염의 전해질 수용액을 주성분으로 하는데, 원사의 유연성, 습윤성, 수 침투성을 높이기 위해 조성분(助成分)으로서 계면활성제, 증점제, 대전방지제 등을 포함할 수도 있다. 본 발명 조성물은 농도가 10% 미만의 I a족 금속염 NaCl, KCl, Na2SO4, K2SO4중에서 선택된 1종 또는 2종이상의 무기염 수용액 조성물로 구성된다. 조성분은 전체 조성물 양에 대해 음이온 및/또는 비이온 계면활성제 0.5~1중량%, 증점제 0.05~0.1중량%, 대전방지제 0.4~1중량%로 구성된다. 이외에 유효량의 기포안정제가 포함될 수 있다. 본 발명조성물을 실에 부여하는 처리방법으로는 첫째, 원사를 점보보빈에 감기전 본 발명 조성물에 침적시키는 방법, 둘째, 급사(給絲) 스탠드에서 점보보빈(jumbo bobbin)에 감겨진 원사에 스프레이로 분무하는 방법, 셋째, 연사하기 전에 초기 실감기(prin winding)에서 원사를 본 발명 조성물이 들어있는 통으로 유제용 롤러를 사용하여 통과시켜 침착시킨 후 연사하는 방법을 들 수 있다. 앞의 첫째와 두번째 방법은 간편하긴하나 액이 바닥에 흐르거나 비산되어 주위가 불결해질 뿐만 아니라 겉과 속의 침적도가 상이하여 원사의 고른 침적상태를 유지할 수 없는 단점이 있다. 반면 세번째의 방법으로 침적시킬 경우는 원사가 초기에나 말기에나 고르게 침적될 뿐만 아니라 액의 비산도 막을 수 있는 잇점이 있다.An object of the present invention is to provide a weaving method that can prevent the process paper of the water jet loom. Another object of the present invention is to provide a novel process paper prevention composition. The present invention is achieved by weaving a yarn with an aqueous solution composition of an electrically conductive inorganic salt. The process paper prevention composition of the present invention contains an electrolyte solution of an inorganic salt that is well soluble in water as a main component, and may include a surfactant, a thickener, an antistatic agent, and the like as a component to increase the flexibility, wettability, and water permeability of the yarn. have. The composition of the present invention is composed of one or two or more inorganic salt aqueous solution compositions selected from Group I a metal salts NaCl, KCl, Na 2 SO 4 , and K 2 SO 4 having a concentration of less than 10%. The composition consists of 0.5-1 weight% of anionic and / or nonionic surfactant, 0.05-0.1 weight% of thickeners, and 0.4-1 weight% of antistatic agents with respect to the total composition amount. In addition, an effective amount of foam stabilizer may be included. As a treatment method for imparting the composition of the present invention to a yarn, first, a method of depositing a yarn in the composition of the present invention before winding it to a jumbo bobbin, and second, spraying the yarn wound on a jumbo bobbin at a yarn stand. A method of spraying with a furnace, and third, a method in which yarn is passed through a container containing the composition of the present invention in an initial prin winding before the yarn is fired by using an emulsion roller to be deposited and then twisted. Although the first and second methods are simple, the liquid flows to the floor or scatters, and the surroundings are unclean, and the deposits of the outer and inner parts are different so that the yarns cannot be evenly deposited. On the other hand, the third method of depositing the yarns has the advantage of not only depositing the yarn evenly at the beginning or the end, but also preventing the liquid from scattering.

이렇게 침적된 원사는 연사공정 및 열고정(setting)→ 점보보빈→방축(안정)공정을 거쳐 직조기의 위사로 공급되게 된다. 경사용 원사는 침적→연사→열고정→실꽂이(creel)→실감기(warping)→(싸이징)→비밍(beaming)→능취(leasing)→종광기기(reaching)→바듸끼기(reed drowing)의 공정을 거쳐 경사로 사용된다. 본 발명 조성물을 부여한 위사를 사용하여 제직시 오실로스코프(Oscilloscope)로 측정한 위사의 사신호(絲信號) 전압은 15~25volt로서 무처리 위사의 1~2volt에 비해 그 통전성이 월등히 개선되었음을 알 수 있다(표 2 참조).The yarn thus deposited is fed to the weft of the weaving machine through the twisting process, heat setting (setting), jumbo bobbin, and anti-spinning (stable) process. Inclined yarns are immersed → twisted → heat-fixed → threaded (creel) → warping → (sizing) → beaming → leasing → reaching → reed drowing It is used as a slope after the process of. The weaving voltage of the weft measured by the oscilloscope when weaving using the composition of the present invention is 15-25 volts, and it can be seen that the electrical conductivity is significantly improved compared to 1 to 2 volt of the untreated weft. (See Table 2).

본 발명에 사용되는 무기염에는 I a족 금속염인 NaCl, KCl, Na2SO4, K2SO4등 물에 녹아 전도성을 높일 수 있는 전해질 무기염이 이에 해당되는 데 경제적인 이유 및 효과면에서 NaCl이 가장 좋다. 음·이온 계면활성제로는 알킬벤젠황산염, 알킬아릴술폰산염 등이 , 비이온 계면활성제로는 지방산알칸올아미드, 폴리옥시에틸렌알킬에테르 등이 사용된다. 또 본 발명에 적합한 증점제로는 지방산디에타놀아미드, 기포안정제로는 고급지방산아미드 등이 있다. 또한 대전방지제로는 제 4 차암모늄염이 사용된다.Inorganic salts used in the present invention include an electrolyte inorganic salt that can be dissolved in water, such as NaCl, KCl, Na 2 SO 4 , K 2 SO 4 , which is a Group I a metal salt, to increase conductivity. NaCl is the best. Alkylbenzene sulfate, alkylaryl sulfonate, etc. are used as an anionic surfactant, fatty acid alkanolamide, polyoxyethylene alkyl ether, etc. are used as a nonionic surfactant. Thickeners suitable for the present invention include fatty acid diethanolamide, and foam stabilizers include higher fatty acid amides. In addition, a quaternary ammonium salt is used as an antistatic agent.

본 발명조성물의 무기염 수용액은 농도에 관계없이 효과를 발휘하나 농도가 너무 높으면 톱가이드에 고형체가 부착하여 절사의 원인이 되기도 한다. 따라서 수용액의 무기염 농도는 10% 미만이 적당한데 바람직하기로는 5% 이하가 좋다. 10%이상이 되면 원사의 준비과정에서 절사요인이 생긴다.Inorganic salt aqueous solution of the composition of the present invention exhibits an effect regardless of the concentration, but if the concentration is too high, the solid may adhere to the top guide may cause the cutting. Therefore, the inorganic salt concentration of the aqueous solution is preferably less than 10%, preferably 5% or less. If it is more than 10%, there is a cutting factor in the preparation of the yarn.
