Description
본 발명은 친환경 발수 원단의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing eco-friendly water-repellent fabric.
최근 각종 다양한 의류가 개발되고 있으며, 아웃도어 스포츠 산업분야의 성장과 더불어 인체에서 발생하는 열을 외부로 방출하는 통기성이나 투습성, 경량성, 쾌적성 등의 기능이 부여된 기능성 소재 의류가 선호되고 있다. 또한, 세계적으로 웰빙 및 환경에 대한 관심이 증대되면서 환경오염을 유발하지 않고 인체에 무해한 친환경성 소재 의류도 요구되고 있다.Recently, various types of clothing have been developed, and with the growth of the outdoor sports industry, clothing made of functional materials with functions such as breathability, moisture permeability, lightness, and comfort that dissipate heat generated in the human body to the outside are preferred. . In addition, as interest in well-being and the environment increases globally, there is a demand for clothing made of eco-friendly materials that do not cause environmental pollution and are harmless to the human body.
이러한 의류의 원료가 되는 천인 원단에 발수처리를 함으로써 의류의 용도가 광범위하게 확대되고 있다. 그러나 종래 발수처리된 원단의 경우 외표면이 오염물질로 오염된 경우 발수성이 급격히 떨어지며, 원단의 일면에 발수액을 스프레이 방식으로 발수처리하는 경우 세탁과 건조를 반복하는 과정에서 세탁견뢰도가 저하되어 원단 손상이 발생함에 따라 수명이 단축되는 문제가 있다. 특히, 이러한 스프레이 코팅방식의 발수방식은 자외선에 오래 노출될 경우 미세 크랙이 유발될 수 있고, 이로 인해 방수력이 떨어지는 단점도 있다.By applying water-repellent treatment to fabric, which is the raw material for such clothing, the uses of clothing are expanding widely. However, in the case of conventional water-repellent treated fabrics, water repellency drops sharply when the outer surface is contaminated with contaminants, and when water-repellent treatment is applied to one side of the fabric by spraying a water-repellent solution, washing fastness deteriorates during repeated washing and drying, causing the fabric to There is a problem that the lifespan is shortened as damage occurs. In particular, this spray coating type water repellent method has the disadvantage of causing micro cracks when exposed to ultraviolet rays for a long time, which results in lower water resistance.

상기 탄소수가 6개인 불소계 발수제 또는 비불소계 발수제로 발수처리함으로써 발수액이 제 1원사의 조직 내부로 침투함은 물론 제 1원사 표면에 코팅되어 매우 견고한 발수능력을 발휘할 수 있다.By treating the water repellent with the fluorinated water repellent having 6 carbon atoms or the non-fluorinated water repellent, the water repellent liquid not only penetrates into the structure of the first yarn, but is also coated on the surface of the first yarn to exhibit very strong water repellent ability.
상기 탄소수가 6개인 불소계 발수제 또는 비불소계 발수제의 농도는 원사의 종류나 굵기에 따라 달라질 수 있으며, 발수처리는 제 1원사를 발수액에 침지함으로써 수행할 수 있다. 상기 원사의 발수액 내 침지시간은 대략 30분 내지 2시간 정도일 수 있으나 이에 제한되는 것은 아니며, 상기 침지시간은 발수액의 농도나 첨가 촉매제 등의 부가 여부에 따라 달라질 수 있다.The concentration of the fluorinated water repellent or non-fluorinated water repellent having 6 carbon atoms may vary depending on the type or thickness of the yarn, and the water repellent treatment can be performed by immersing the first yarn in a water repellent solution. The immersion time of the yarn in the water-repellent solution may be approximately 30 minutes to 2 hours, but is not limited thereto, and the immersion time may vary depending on the concentration of the water-repellent solution or the addition of an additional catalyst.
상기 탄소수가 6개인 불소계 발수제로는 아사히 그라스(Asahi Glass)제 AG-E500D 등이 사용될 수 있으며, 탄소수가 6개인 비불소계 발수제로는 독일 헌츠만(Huntsman)제 Phobotex RHP 등이 사용될 수 있으나, 이에 제한되는 것은 아니다.As the fluorine-based water repellent having 6 carbon atoms, AG-E500D manufactured by Asahi Glass, etc. may be used, and as the non-fluorinated water repellent having 6 carbon atoms, Phobotex RHP manufactured by Huntsman, Germany, etc. may be used. It is not limited.
또한, 상지 제 1원사를 발수처리한 후 제 1원사에 코팅되고 남은 잉여 발수액을 탈락시키는 과정인 탈수단계를 추가로 더 수행할 수 있다.In addition, after water-repelling treatment of the upper limb first yarn, a dehydration step, which is a process of removing excess water-repellent liquid coated on the first yarn and remaining, may be additionally performed.
또한, 상기 탈수단계 이후 건조단계를 추가로 더 수행할 수 있다.Additionally, a drying step may be additionally performed after the dehydration step.
상기 제 2원사는 공정수분율이 8% 이상인 면, 양모, 레이온 등의 천연섬유일 수 있으며, 친수성 기능을 갖는다.The second yarn may be a natural fiber such as cotton, wool, or rayon with a process moisture content of 8% or more and has a hydrophilic function.
상기 발수처리된 제 1원사를 위사로 하여 내층을 제직하고, 공정수분율이 8% 이상인 제 2원사를 경사로 하여 외층을 제직하는 단계는 원단을 직조하는 과정이다. 이때 상기 내층의 밀도는 상기 외층의 밀도보다 10 내지 50 부피% 더 조밀한 것이 바람직하다. 내층의 밀도가 표면층의 밀도에 비해 10% 미만으로 조밀하면 내층을 구성하는 소수성 섬유가 갖는 척력이 외층을 구성하는 흡수력과 비슷하여 방수기능을 갖지 못하며, 50% 이상 조밀하면 인체의 땀이 외층으로 용이하게 전이되지 못하여 투습기능이 저하될 수 있다.The step of weaving the inner layer using the water-repellent treated first yarn as a weft yarn and weaving the outer layer using the second yarn with a process moisture content of 8% or more as the warp yarn is a process of weaving the fabric. At this time, the density of the inner layer is preferably 10 to 50% by volume denser than the density of the outer layer. If the density of the inner layer is less than 10% of the density of the surface layer, the repulsive force of the hydrophobic fibers that make up the inner layer is similar to the absorption power that makes up the outer layer, so it does not have a waterproof function. If it is more than 50% dense, the body's sweat flows into the outer layer. Because it is not easily transferred, moisture permeability may be reduced.
상기 폴리우레탄 발수코팅 수지액은 피복 건조 시 물방울은 통과하지 못하나 수증기는 통과할 수 있는 미세한 기공을 형성함으로써 피복되는 원단이 방수투습성을 갖도록 하는 역할을 하며, 폴리우레탄 발수코팅 수지액을 1차 및 2차로 단계적으로 침지하고 가열처리함으로써 초기 발수성뿐만 아니라 발수성에 대한 유지력을 향상시킬 수 있다.The polyurethane water-repellent coating resin solution serves to ensure that the coated fabric has waterproof and moisture-permeable properties by forming fine pores that do not allow water droplets to pass through when the cloth is dried, but allow water vapor to pass through. The polyurethane water-repellent coating resin solution is used as a primary and By secondary immersion and heat treatment, not only the initial water repellency but also the retention of water repellency can be improved.
상기 내층과 외층으로 이루어진 원단을 폴리우레탄 발수코팅 수지액에 침지시킬 때 유연성이 저하되는 것을 방지하기 위해 제 1폴리우레탄 발수코팅 수지액에는 가교제를 포함하지 않은 상태로 원단을 침지 및 가열 처리한 후 제 2폴리우레탄 발수코팅 수지액에는 가교제를 포함시킨 상태로 원단을 침지 및 가열 처리하는 것이 바람직하다.In order to prevent flexibility from being reduced when the fabric consisting of the inner and outer layers is immersed in the polyurethane water-repellent coating resin solution, the fabric is immersed and heated in the first polyurethane water-repellent coating resin solution without containing a crosslinking agent. It is preferable to immerse and heat the fabric while containing a crosslinking agent in the second polyurethane water-repellent coating resin solution.
상기 가교제는 폴리우레탄 수지의 가교반응을 촉진하여 원단에 대한 폴리우레탄 수지의 접착력을 높이면서 속건성을 부여하는 역할을 한다.The crosslinking agent promotes the crosslinking reaction of the polyurethane resin and serves to increase the adhesion of the polyurethane resin to the fabric and provide quick drying.
제 1 및 제 2폴리우레탄 발수코팅 수지액 침지 단계는, 상기 원단을 미리 준비된 발수코팅 수지액에 담궈 원단을 이루는 원사의 조직 내에 발수코팅 수지액이 침투하게 하여 발수코팅 수지액이 섬유소의 표면을 감싸 코팅하게 하는 과정으로, 이때 사용되는 발수코팅 수지액의 농도는 원사의 종류나 굵기에 따라 달라질 수 있다. 상기 원단의 발수코팅 수지액 내 침지시간은 약 30분 내지 1시간일 수 있으나, 이에 제한되는 것은 아니며, 침지시간은 발수액의 농도나 첨가 촉매제 등의 부가 여부에 따라 얼마든지 변경 가능하다.In the first and second polyurethane water-repellent coating resin solution immersion steps, the fabric is immersed in a previously prepared water-repellent coating resin solution to allow the water-repellent coating resin solution to penetrate into the tissue of the yarn forming the fabric, so that the water-repellent coating resin solution penetrates the surface of the cellulose. This is a process of wrapping and coating, and the concentration of the water-repellent coating resin used at this time may vary depending on the type or thickness of the yarn. The immersion time of the fabric in the water-repellent coating resin solution may be about 30 minutes to 1 hour, but is not limited thereto, and the immersion time can be varied depending on the concentration of the water-repellent solution or the addition of an additional catalyst.
상기 제 1폴리우레탄 발수코팅 수지액 또는 상기 제 1 및 제 2폴리우레탄 발수코팅 수지액은 수지액 중에 용제로 희석한 불소계 또는 실리콘계 발수제를 함유할 수 있으며, 상기 불소계 또는 실리콘계 발수제를 소요량 첨가함으로써 초기 발수성뿐만 아니라 발수성에 대한 유지력을 향상시킬 수 있다.The first polyurethane water-repellent coating resin solution or the first and second polyurethane water-repellent coating resin solutions may contain a fluorine-based or silicone-based water repellent diluted with a solvent in the resin solution, and the initial amount is added by adding the required amount of the fluorine-based or silicone-based water repellent. It can improve not only water repellency but also water repellency retention.
상기 제 1폴리우레탄 발수코팅 수지액에는 촉진제, 항균제 등의 성분이 추가로 더 포함될 수 있다. 이때 촉진제는 폴리우레탄 수지의 가교반응 시 촉매로 작용함으로써 원단에 대한 폴리우레탄 수지의 접착력을 더욱 향상시키는 효과가 있으며, 항균제는 제조 후 원단이 미생물 등에 의해 변화되지 않도록 하는 역할을 한다.The first polyurethane water-repellent coating resin solution may further contain ingredients such as accelerators and antibacterial agents. At this time, the accelerator has the effect of further improving the adhesion of the polyurethane resin to the fabric by acting as a catalyst during the crosslinking reaction of the polyurethane resin, and the antibacterial agent plays a role in preventing the fabric from being changed by microorganisms etc. after manufacturing.
일 예로, 상기 제 1폴리우레탄 발수코팅 수지액은 폴리우레탄 수지 100 중량부에 대하여, 발수제 5 내지 30 중량부, 촉진제 3 내지 9 중량부, 항균제 0.1 내지 2 중량부를 포함할 수 있다.As an example, the first polyurethane water-repellent coating resin solution may include 5 to 30 parts by weight of a water repellent, 3 to 9 parts by weight of an accelerator, and 0.1 to 2 parts by weight of an antibacterial agent, based on 100 parts by weight of the polyurethane resin.
상기 제 2폴리우레탄 발수코팅 수지액에는 항균제, 방염제, 안료, 소광제 등의 성분이 추가로 더 포함될 수 있다. 여기서 방염제는 원단에 불을 붙인 후 불꽃을 제거했을 때 원단이 스스로 연소되거나 번지지 않도록 하기 위하여 첨가되는 성분이며, 외부의 불에 대한 안정성을 확보하는 역할을 한다. 방염제는 일 예로, 세륨 산화물 또는 안티몬 산화물 등 고도의 난연성을 갖는 물질일 수 있다. 안료는 원료에 착색을 하기 위해 첨가되는 성분이며, 소광제는 원단 표면의 광택을 조절하는 역할을 한다.The second polyurethane water-repellent coating resin solution may further contain ingredients such as antibacterial agents, flame retardants, pigments, and matting agents. Here, the flame retardant is an ingredient added to prevent the fabric from burning or spreading on its own when the fabric is ignited and the flame is removed, and it plays a role in ensuring stability against external fire. For example, the flame retardant may be a material with a high degree of flame retardancy, such as cerium oxide or antimony oxide. Pigments are ingredients added to color raw materials, and matting agents play a role in controlling the gloss of the fabric surface.
일 예로, 상기 제 2폴리우레탄 발수코팅 수지액은 폴리우레탄 수지 100 중량부에 대하여, 발수제 5 내지 30 중량부, 가교제 4 내지 12 중량부, 항균제 0.1 내지 2 중량부를 포함할 수 있다.As an example, the second polyurethane water-repellent coating resin solution may include 5 to 30 parts by weight of a water repellent, 4 to 12 parts by weight of a crosslinking agent, and 0.1 to 2 parts by weight of an antibacterial agent, based on 100 parts by weight of the polyurethane resin.
