또한 천연삼 섬유(natural hemp fiber)는 대마, 황마, 아마, 양마, 저마 모두를 포함하는 천연삼 섬유이고, 웨이브(wave) 형의 저융점 열가소성수지 섬유(low melting thermoplastic fiber)는 저융점 폴리푸로피렌 섬유, 아크릴 섬유, 초산비닐섬유를 포함한다.The natural hemp fiber is a natural hemp fiber including all hemp, jute, flax, hemp, and hemp. The wave-type low melting thermoplastic fiber is a low melting polyolefin Pyrene fibers, acrylic fibers, and vinyl acetate fibers.
본 발명은 천연삼 장섬유(1.2m~3m)를 5cm~10cm로 재단하여 침지조성물(액)에 침지하여 탈수하고 건조한 삼섬유와 웨이브형의 저융점 열가소성 합성수지 섬유를 상술한 다용도 기능성 솜에 혼합하므로서 다용도 기능성의 솜의 취약점이라 할 수 있는 인장강도 및 파열강도의 물성향상, 스티프니스성(stiffness quality)의 향상으로 지지력 보강, 극심한 부피감소 방지로 형태 유지성의 개선, 섬유간의 이완 또는 밀림 현상에 의한 변형 방지로 치수안정성을 확보할 수 있는 다용도 기능성 혼합솜과 그 제조방법을 제공함에 있다 하겠다.The present invention relates to a method for producing a multi-purpose functional cotton sheet, which comprises cutting a natural tri-long fiber (1.2 m to 3 m) into 5 cm to 10 cm, immersing it in an immersion composition The improvement of the properties of tensile strength and tear strength, which is a weak point of multi-purpose functional cotton, the improvement of stiffness quality, the improvement of shape retention by prevention of extreme volume reduction, the improvement of stiffness quality, The present invention provides a versatile functional mixture cotton capable of securing dimensional stability by preventing deformation and a method of manufacturing the same.
본 발명의 기술 분야에 속하는 섬유소재로서 난연(방염)성을 갖는 유리섬유, 석면, 암면 글라스울, 셀라쿨 등이 있으나 석면은 인체의 유행성 문제로 인해 현재 사용이 금지되고 있으며 유리섬유, 글라스울, 세라쿨 등은 쉽게 분말이나 소편이 되므로서 인체에 피부병 등을 유발시키므로서 사용이 감소되는 추세에 있다. 또한 합성수지 섬유소재로는 난연성(방염성)의 아라미트 섬유, 노멕스, 포리아미드 섬유 등이 있으나 300℃ 이상에서는 연화되거나 용융되고 400℃ 이상에서는 분해되므로 사용이 한정되며 고가이고 석유화학 제품으로서 환경오염을 유발시키는 문제점을 않고 있다.Asbestos fibers are currently prohibited due to the pandemic of the human body, and fiberglass, glass wool, etc. are used as textile materials belonging to the technical field of the present invention. , Ceracool and the like are easily powdered or small pieces, thereby causing skin diseases and the like in the human body. In addition, synthetic resin fiber materials include flame retardant (aramid) fibers, Nomex, and polyamide fibers. However, they are softened or melted at temperatures above 300 ° C and decomposed above 400 ° C. And the like.
또한 천연 면솜은 우리 생활 주변에 흔하게 사용되는 섬유로서 그 성분은 셀룰로우스(cellulose)라 불리는 섬유소가 90% 이상이고 그 밖에 약간의 지방과 리그닌으로 이루어져 있다. 솜은 많은 중공(lumen)으로 이루어져 꼬임을 하고 있어서 열이 전달되는 것을 막는 단열 및 보온재 역할을 한다.In addition, natural cotton wool is a fiber commonly used in our daily life. It consists of more than 90% of cellulose called cellulose, and also contains some fat and lignin. The cotton is made of many hollow lumens and is twisted to serve as an insulation and insulating material to prevent the heat from being transferred.
다시말하면 솜과 솜 사이에 존재하는 많은 공간에 공기가 들어 있어 열의 이동을 막는 것이다.In other words, there is air in many spaces between cotton and cotton to prevent the movement of heat.
공기는 다른 단열재보다 단열효과가 우수하므로 천연 면솜은 보온성, 단열성, 흡음성이 뛰어나면서도 유해성분이 없고 환경 공해를 유발하지 않는 특징이 있다. 그러나 천연 면솜은 난연(방염)성이 취약하고 흡습성이 강하며 곰팡이 및 세균의 번식이 용이한 결점이 있다. 그 외에도 미세 먼지를 일으키고 인장강도와 작업성이 나쁘다. 이와 같은 이유로 면솜은 이부자리나 의류로 사용하는 것으로 인식될 뿐 다양한 산업분야에 이용되기에는 어렵다.Since air has better insulation than other thermal insulation materials, natural cotton swabs are excellent in heat insulation, heat insulation, and sound absorption, but have no harmful components and do not cause environmental pollution. However, natural cotton swabs have poor flame retardancy, strong hygroscopicity, and are easily defective in the growth of fungi and bacteria. It also causes fine dust, and has poor tensile strength and workability. For this reason, cotton swabs are perceived to be used as bedclothes and clothing, and are difficult to be used in various industrial fields.
상기와 같은 천연 셀룰로우즈계 섬유를 산업분야의 소재로 이용하기 위한 노력으로 셀룰로우즈계 섬유를 난연화하기 위해 브롬계, 염소계와 같은 할로겐계, 인계, 붕소계 등의 난연제에 함침한 후 건조시켜 난연화 소재를 시도하고 있으나 섬유표면이 코팅되어 있으므로 해서 난연성은 유지할 수 있으나 보온성, 흡음성 등이 감소하므로 해서 소기의 목적을 달성함에는 많은 문제가 있다. 뿐만 아니라 할로겐 화합물 중 브롬화합물은 다이옥신류 등 발암물질의 생성 위험성이 뒤따르게 되는 문제점도 있다. 본원 선원 발명 역시 천연 셀루로우즈계 섬유를 산업분야의 소재로 이용하기 위한 노력의 일환으로서 천연 면솜의 본래의 기능을 살리면서 난연성, 발수성, 인장강도, 파열강도 등의 물성을 향상시킨 다용도 기능성 솜을 개발하게 되므로서 산업소재로서 큰 성과를 달성하게 되었다.In order to use such natural cellulosic fibers as materials for industrial fields, it has been impregnated with flame retardants such as halogen-based, phosphorus-based, and boron-based flame retardants such as a bromine-based or chlorine- However, since the surface of the fiber is coated, the flame retardancy can be maintained. However, there is a problem in achieving the desired purpose by reducing the heat insulation and the sound absorption. In addition, there is a problem that a bromine compound in a halogen compound is accompanied by a risk of generation of carcinogenic substances such as dioxins. The present invention also relates to a multi-purpose functional cotton which has improved physical properties such as flame retardancy, water repellency, tensile strength and tear strength while making use of the natural function of natural cotton as part of efforts to use natural cellulosic fibers as materials for industrial fields And it has achieved great achievement as an industrial material.
그러나 시간 경과에 따라 부피 감소로 원형 복원이 어렵고 결합력이 부족해 섬유 간의 이완성이 커서 형태 변화가 발생하며 스티프성이 부족하여 지지력이 부족하므로서 산업소재로서 용도가 한정되고 물성 또한 만족스럽지 못하다.However, it is difficult to restore the circular shape due to the decrease in volume over time, and due to the lack of bonding force, there is a large degree of relaxation between the fibers, resulting in a change in shape.
이상과 같은 문제점을 개선하기 위해 본원 출원인의 선등록 발명인 다용도 기능성 솜에 천연삼 섬유 및 웨이브형 저융점 열가소성수지섬유를 첨가 균질성의 혼합 섬유 소재를 얻게 되므로서 부피감소율을 줄이므로서 형태 변화방지, 스티프니스성(stiffness quality)의 향상으로 지지력 보강, 섬유 간의 이완 및 밀림 현상 방지로 원형유지, 인장강도 및 파열강도의 물성을 보강한 다용도 기능성 혼합솜 및 그 제조방법을 제공하고자 한다.In order to solve the problems described above, it is possible to obtain a homogeneous mixed fiber material by adding a natural triple fiber and a wavy low melting point thermoplastic resin fiber to a versatile functional cotton of the present applicant, thereby reducing the volume reduction rate, The present invention provides a multi-purpose functional mixture cotton reinforced with circular stiffness, tensile strength and rupture strength by reinforcing the supporting force, preventing loosening and sagging between fibers due to improvement of stiffness quality, and a manufacturing method thereof.

상기 본 발명 천연삼 섬유 침지액에 사용되는 제1인산암모늄은 천연삼의 주성분인 셀룰로우즈와 쉽게 결합하며 산화되면 탈수작용을 하는 기능을 가진다. 인화합물의 분자는 사슬상의 폴리머로 되어 있어 천연삼 섬유에 무수히 존재하는 중공 부분에 침투하여 부착된다. 고열이 발생하면 인화합물의 폴리머는 분해 산화되어 탈수작용을 하는 인화합물로 변한다. 또한 인화합물은 삼섬유로부터 물을 빼앗아 난연성(방염성)을 가지며 냉각 및 질식 억제 작용을 하고 산화인 자체는 물과 결합하여 폴리인산으로 되어 삼의 섬유를 덮어 산소를 차단하는 기능을 가진다.The ammonium phosphate monobasic ammonium phosphate used in the present invention is easily combined with cellulose, which is a main component of natural hemp, and has a function of dehydrating when it is oxidized. The molecules of the phosphorus compound are in the form of a chain polymer, and they penetrate and adhere to hollow portions which are present in the natural trifibers. When a high temperature occurs, the polymer of the phosphorus compound changes into a phosphorus compound which is decomposed and oxidized to perform a dehydration function. In addition, the phosphorus compound removes water from the ternary fiber and has flame retardancy (flame retardancy) and functions to suppress cooling and asphyxiation. The oxidant phosphor itself has a function of blocking oxygen by covering polyphosphoric acid with water and covering the fiber.
붕산은 방부, 살균, 살충 기능이 있어 섬유의 변질 부패를 방지하고 곰팡이와 벌레들이 발생하지 않으며 불을 붙지 않게 하거나 타오르는 불을 꺼지게 하는 난연성(방염성)을 갖는 기능성 물질이라 할 수 있다.Boric acid is a functional material with flame retardancy (flame retardancy) which prevents the decay of fiber and prevents molds and insects, and keeps the flames from burning off due to its preservation, sterilization and insecticidal function.
또한 음이온계면활성제는 서로 혼합되지 않는 액체를 균일하게 혼합하여 에멀죤화 하므로서 천연삼 조성물을 균질화시키며 분산을 잘되도록 한다.In addition, anionic surfactants are used to uniformly mix liquids that are not mixed with each other and emulsify them, thereby homogenizing and dispersing the natural three compositions.
황산알킬암모니움(ROSO3NH4), 반경화우지의 소오다 비누, 라우릴설페이트 소다염, 알킬벤젠술폰산염의 음이온 계면활성제를 사용할 수 있다.Anionic surfactants such as alkylammonium sulfate (ROSO 3 NH 4 ), soda soap of semi-hardened tallow, lauryl sulfate sodium salt, and alkylbenzenesulfonate salt may be used.
불소계 발수제는 퍼프루오러 아크릴레이트(perfluoro acrylate)를 사용할 수 있고 방습을 위해 사용되며 고도의 발수성과 발유성을 나타낸다.The fluorinated water repellent agent can use perfluoro acrylate and is used for moisture proofing and exhibits high water repellency and oil repellency.
인산 아크릴계 커플링제(coupling agent)는 조성물 간의 결합과 천연삼 섬유와 조성물 간의 결합을 강화시킨다. 분산제는 침지용액을 균질화시키며 삼 섬유조직에 침지 용액의 침투성을 높인다. 또한 본 발명에 사용되는 섬유들로서 다용도 기능성 솜은 면섬유에 면섬유 침지용 조성물을 침지하므로서 난연성, 내부식성, 발수성, 발유성 등의 기능성이 부여된 면섬유라 할 수 있고 본래의 면섬유에 비해 인장강도 및 파열강도의 물성이 보강되었으며 그 외에도 보온성, 보냉성, 흡음성, 차음성, 내진동성, 공기 정화 기능이 있어 주택을 비롯한 건축물에 에너지 절감과 탄소 저감을 위한 소재로 사용될 수 있다. 그러나 본래의 면섬유는 섬유장이 짧고 가늘고 약한 단섬유로서 너무 부드러워 지지력이 부족하고 체적 변화가 심하여 섬유간에 이완과 밀림현상으로 변형이 심한 물성을 가지고 있어 천연면을 개선시킨 다용도 기능성 솜에서도 상기 취약점이 크게 개선될 수는 없었다. 이로 인해 주택을 비롯한 건축물 그 밖에 산업용 용도로서 제한성이 있다.The phosphoric acid-based coupling agent enhances the bonding between the compositions and the bonding between the natural fiber and the composition. The dispersing agent homogenizes the immersion solution and enhances the permeability of the immersion solution to the three-fiber structure. Also, as the fibers used in the present invention, the multi-purpose functional cotton can be a cotton fiber imparted with functions such as flame retardance, corrosion resistance, water repellency, oil repellency, etc. by immersing the composition for cotton fiber immersion into cotton fiber. Strength properties are reinforced. In addition, it can be used as a material for energy saving and carbon reduction in buildings including houses, because it has warmth, cold, sound absorption, sound insulation, vibration proof and air purification function. However, since the original cotton fiber is short, thin and weak short fiber, it is so soft that it has insufficient bearing capacity and has a large volume change, so that it has a property of deformation due to relaxation and jumping phenomenon of the fibers. Therefore, even in versatile functional cotton, It could not be improved. As a result, there are limitations in applications such as housing, buildings and other industrial applications.
본 발명에서 사용되는 천연삼은 황마, 아마, 양마, 저마를 포함하는 삼으로서 본래의 물성이 빳빳한 성질 즉 스티프니스성이 우수하고 장섬유로서 섬유올이 굵고 인장력이 강한 셀룰로우즈로서 이를 다용도 기능성 솜에 접목시키므로서 면섬유에 부여된 고유의 특성을 살리면서 면섬유의 취약한 물성인 인장강도 및 파열강도의 물성 개선과 지지력을 강화시킨 소재를 얻을 수 있다.The natural wax used in the present invention is a cellulose having excellent physical properties such as jute, flax, yam and jama, which is excellent in stiffness, and is a long fiber having a thick fiber and a high tensile strength. By combining the inherent properties imparted to the cotton fiber, it is possible to obtain a material which improves the physical properties of the tensile strength and the burst strength, which are weak physical properties of the cotton fiber, and the supporting force.
한편 섬유의 혼합과정에서 면섬유는 단섬유이여서 큰 문제가 없지만 삼섬유는 장섬유이기 때문에 절단해서 사용하지만 섬유장을 짧게 한 것을 사용하면 혼합과정에서 일측으로 몰리어 집적되는 현상이 발생하고 길게 재단한 삼섬유는 서로 엉키어 작업성이 좋지 않고 균질성의 혼합섬유를 기대하기 어렵다. 수 많은 실험을 통하여 얻어진 결과로는 50mm~10mm 섬유를 사용하는 것이 작업성과 혼합솜의 물성(인장강도 및 압축강도) 면에서 유리한 길이 범위라 할 수 있다.On the other hand, in the mixing process of fiber, cotton fiber is not a big problem because it is short fiber, but since triple fiber is long fiber, it is cut and used. However, when fiber length is shortened, it is accumulated in one side in mixing process, It is difficult to expect homogeneous mixed fibers having poor workability due to tangling with each other. The results obtained through numerous experiments show that the use of 50 mm to 10 mm fibers is an advantageous range in terms of workability and physical properties (tensile strength and compressive strength) of the mixed cotton.
그 밖에 사용되는 섬유로서 웨이브 형상의 저융점 열가소성 합성수지 섬유가 있다. 이는 혼합섬유를 타면해서 다용도 기능성 혼합솜 소재를 얻게 되는데 부직포 형태의 다수면을 적층시켜 판상체 형태로 얻게 된다. 판상체 형태에서는 다용도 기능성 솜의 섬유와 침지용 조성물이 함침된 삼섬유들과 지그재그 또는 복잡한 형태로 얽혀 있는 상태이나 온도 80~150℃로 가압 열처리하면 웨이브형의 저융점 열가소성 수지 섬유는 연화되거나 표면이 용유되면서 면섬유와 삼섬유를 결착시키고 결착시킨 상태로 냉각되어 고화하게 된다. 이는 섬유와 섬유 간의 결합력을 강화시키므로서 섬유 간의 이완이나 밀림현상이 발생하지 않고 부피변화를 줄일 수 있어 변형을 방지함과 동시에 치수안정성을 확보할 수 있는 다용도 기능성 혼합솜의 소재를 얻을 수 있다. 그 밖에도 천연삼을 대체할 수 있는 섬유로서 칡넝쿨 섬유와 야자무피 섬유가 있으며 이와 같은 섬유를 동일한 방법으로 처리하여 삼섬유 대신 사용하여 본 결과 삼을 사용한 다용도 기능성 솜 소재와 물성이나 기능성에 있어서 큰 차이가 없으므로 재료 구입이나 단가 면에서 문제점이 없으면 삼섬유 대신 사용할 수 있다.As other fibers used, there is a wave-like low melting point thermoplastic synthetic resin fiber. This results in a versatile functional mixed cotton material obtained by rubbing mixed fibers. In the case of the plate shape, when the multi-purpose functional cotton fibers and the dipping composition are entangled with the three-fibers impregnated in a staggered or complicated form, if the heat treatment is performed at a temperature of 80 to 150 ° C, the wavy low melting point thermoplastic resin fibers are softened As a result, the cotton fiber and the trilobite are bound to each other, and they are cooled and solidified. This enhances the bonding force between the fibers and the fibers, so that the volume change can be reduced without causing relaxation or swelling of the fibers, so that a multi-purpose functional mixed cotton material can be obtained that can prevent deformation and ensure dimensional stability. In addition, there are various kinds of fibers that can replace natural fibers, such as 칡 쿨 쿨 섬유 와 야 야 야 야 섬유 섬유 섬유 섬유 섬유 섬유 쿨 쿨 쿨 쿨 쿨 처리 처리 처리 처리 처리 처리 처리 처리 처리 처리 처리 처리 처리 차이 차이 차이 차이 차이 차이 차이 It can be used instead of ternary fiber if there is no problem in terms of material purchase or unit cost.
이상에서 웨이브형 저융점 열가소성 수지로서는 핫멜트 수지로 사용되는 대표적인 수지로서 에티렌 초산 비닐 공중합 수지(EVA) 수지 저밀도 폴리에티렌 수지, MMA수지, PP수지의 섬유를 사용할 수 있으며 열처리 온도 범위는 90~160℃로서 EVA수지, 저밀도 폴리에티렌 경우는 분자량 12,000~24,000 일때 연화점이 102~110℃ 범위이고 EVA수지는 초산비닐 함유량에 따라 연화점이 달라질 수 있으나 일반적으로 연화점이 70℃이고 90℃에서는 용융되며 접착성이 좋다. 폴리푸로피렌이나 MMA수지는 열변형 온도나 연화점이 높으며 140℃ 이상에서는 연화되고 170℃에서는 용융되므로 열처리 온도 범위의 폭이 크다. 또한 완전 용융시키면 섬유로서 기능이 상실되므로 대략 연화점과 용융점 사이에서 수지의 열 특성에 따라 열처리 온도를 선택할 수 있다. 또한 웨이브 형상의 합성수지 섬유를 사용하는 이유는 면섬유나 삼섬유의 접촉면을 넓힐 수 있고 상하로 위치하는 면섬유나 삼섬유를 접착 결착시킬 수 있다.As the wavy low melting point thermoplastic resin, ethylene-vinyl acetate copolymer (EVA) resin low density polyethylene resin, MMA resin and PP resin fiber can be used as a typical resin used as a hot-melt resin, The EVA resin has a softening point in the range of 102 to 110 ° C when the molecular weight is 12,000 to 24,000 and the softening point varies depending on the vinyl acetate content in the case of the low-density polyetylene but is generally melted at 90 ° C Good adhesion. Polypropylene and MMA resins have high heat distortion temperature and softening point. They soften at 140 ° C or higher and melt at 170 ° C, which means that the heat treatment temperature range is wide. In addition, since the function as the fiber is lost when it is completely melted, the heat treatment temperature can be selected between the approximate softening point and the melting point according to the thermal characteristics of the resin. The reason for using the wave-shaped synthetic resin fiber is that the contact surface of the cotton fiber or the hemp fiber can be widened, and the cotton fiber or the hemp fiber located up and down can be bonded and bonded.
그 밖에도 합성수지 섬유에 분말상의 난연재를 5~10중량% 첨가시켜 방사한 상기 수지 섬유를 사용하여 난연성을 높일 수도 있다.In addition, it is also possible to increase the flame retardancy by using the resin fiber spun by adding 5 to 10 wt% of powdered flame retardant to the synthetic resin fiber.
이상의 방법으로 제조된 다용도 기능성 혼합솜의 소재는 우선 다용도 기능성 솜 소재에 비해 압축강도, 파열강도, 내압성이 크게 향상되었으며 삼섬유의 첨가로 스티프니스성의 향상으로 지지력이 크게 보강되었으며 체적(부피)감소율을 획기적으로 낮출 수 있었고 합성수지 섬유가 혼합되므로서 섬유 간의 접착력과 결속력이 보강되므로서 섬유 간의 이완 또는 밀림현상이 발생하지 않아 원형을 지속적으로 유질할 수 있고 삼섬유와 함께 외압에 의한 부피 감소율을 크게 줄일 수 있는 상승효과도 기대할 수 있으며 이로 인해 치수안정성을 확보할 수 있어 시공이 편리하고 시공 후의 하자가 발생하지 않는 특성과 함께 다른 소재에 비해 가볍고 우수한 보온성, 단열성, 흡음성, 진동흡수성, 방충성, 발수성을 지니고 있어 주택을 비롯한 각종 건축물에 에너지 절감, 탄소 저감에 이바지 할 수 있으며 조선, 우주항공, 자동차 방음재, 보온재 등 산업분야에 광범위하게 이용될 수 있는 다용도 기능성 혼합솜이라 할 수 있다.Compressive strength, tear strength, and pressure resistance of the multifunctional functional cotton fabric prepared by the above method were greatly improved compared to the multifunctional functional cotton fabric. The addition of trilobite greatly enhanced the bearing capacity due to the improvement of the stiffness and the volume (volume) reduction rate Since synthetic resin fibers are mixed with each other, the adhesive force and bonding force between fibers are reinforced, so that there is no loosening or squeezing phenomenon between the fibers. Therefore, it is possible to continuously maintain the original shape and reduce the volume reduction rate by the external pressure It can be expected to have a synergistic effect to be able to secure the dimensional stability. Therefore, it is convenient to construct and does not cause defects after construction, and is light and excellent in thermal insulation, insulation, sound absorption, vibration absorbing property, House and other buildings. It can contribute to energy savings, carbon reduction, and may be referred to as a mixed-purpose functionality that can be widely used in shipbuilding, aerospace, automotive soundproofing, insulation, etc. cotton industry.
