Description

청 원단 직물의 방수, 발수를 위한 코팅처리 가공방법{Coating processing method for waterproof and water emission of blue textiles}Coating processing method for waterproof and water emission of blue textiles}

본 발명은 청 원단 직물의 방수, 발수를 위한 코팅처리 가공방법에 관한 것으로 특히, 주로 청바지 소재로 사용되는 청 원단의 표면에 스티렌과 부타디엔을 혼성중합한 공중합체에 물 등의 물질을 첨가하여 혼련된 코팅제를 사용하여 방수(water proof) 및 발수(water repellent) 기능이 극대화 되도록 코팅 처리하는 가공 방법에 관한 것이다.The present invention relates to a coating processing method for waterproofing and water repellent of a blue fabric, in particular, kneading by adding a material such as water to a copolymer of styrene and butadiene hybridized on the surface of a blue fabric mainly used as a jeans material. The present invention relates to a processing method of coating the coating to maximize the water proof and water repellent functions.

주지하는 바와 같이 청 원단은 데님이라고도 불리우며, 면 섬유로 두껍게 직조되어 수분 흡수가 빨리 되기 때문에 비를 맞게되면 수분에 의하여 가죽같이 뻣뻣해져 걸음을 걷기조차 힘든 상태가 된다.As is well known, blue fabric is also called denim, and it is woven from cotton fiber to absorb moisture quickly, so when it is rained, it becomes hard to walk even when it is rained by leather.

종래에도 면직물에 방수 발수 특성을 부여하기 위하여 폴리에스터 우레탄 코팅(polyester urethane coating)이나 비져블 코팅(visible coating) 등을 실시하였는데, 한번의 코팅만으로는 원하는 방수 발수특성을 나타낼 수 없으며, 만약 원하는 방수 발수 특성을 나타낼 정도로 여러번의 코팅을 실시할 경우에는 면 특유의 부드러운 성질을 변화시키게 되어 질감을 상실하게 되는 결점이 있었다.Conventionally, polyester urethane coating or visible coating has been applied to give a water repellent property to a cotton fabric. However, a single coating cannot exhibit the desired water repellent properties. When the coating is applied many times, the softness of the cotton may be changed, resulting in a loss of texture.

본 발명은 이와 같은 제결점을 감안 해결하기 위하여 안출한 것으로서, 일반적인 청 원단에 기존의 베이스 코팅을 입히고 그 위에 비져블 코팅을 실시한 후 스티렌 부타디엔 계통의 공중합 라텍스를 포함한 코팅제를 사용하여 한번 더 코팅함으로써 청 원단의 특징은 변화시키지 않으면서도 미약한 방수 발수의 문제점을 해결하는 청 원단 직물의 방수, 발수를 위한 코팅처리 가공방법을 제공하는 데 그 목적이 있다.The present invention has been made to solve the above-mentioned drawbacks, by coating a conventional base coating on a conventional blue fabric, and after performing a visible coating on the coating by using a coating agent including styrene butadiene-based copolymer latex once more blue The purpose of the present invention is to provide a coating treatment method for waterproofing and water repellent of a blue fabric that solves the problem of weak waterproof water repellency without changing the characteristics of the fabric.

이하, 제시되는 바람직한 실시 예에 따라 본 발명을 상세히 설명하면 다음과 같다.본 발명은 전술한 바와 같이 여러번의 코팅공정을 거치지 않아 청 원단의 특성을 변화시키지 않으면서도 방수 발수특성을 원활히 구현하기 위한 방법을 제공하는 것으로, 크게 3번의 공정을 거치게 된다.Hereinafter, the present invention will be described in detail with reference to the presently disclosed embodiments. The present invention does not undergo a plurality of coating processes as described above, so that the water-repellent water-repellent property can be smoothly implemented without changing the characteristics of the blue fabric. By providing a method, it is largely three times.

먼저, 제 1공정으로서 통상의 방법에 의하여 직조되고 염색 및 세척 공정까지 가공 완료된 청 원단 직물의 겉 표면에 베이스 코팅(2차 코팅을 용이하게 하기 위하여 선처리하는 코팅)을 나이프 코팅(knife coating)방법으로 하는 것으로, 이때 나이프 코팅방법이라 함은 청 원단위에 혼합, 혼련된 코팅제를 얹어 놓고 나이프(knife)로 밀어 코팅을 실시하는 것이며, 이와 같이 베이스 코팅이 완료된 청 원단 위에 제 2공정으로서 비져블 코팅(visible coationg)을 실시하게 된다. 이것은 일반적인 폴리에스터 우레탄 코팅의 비져블 코팅과 같은 코팅법을 이용한다.First, as a first process, a base coating (coating which is pretreated to facilitate secondary coating) is coated on the outer surface of a woven fabric fabric which is woven by a conventional method and processed to a dyeing and washing process. In this case, the knife coating method is to put the mixed and kneaded coating agent on the petition unit and push it with a knife to apply the coating. As such, the second coating is performed on the blue fabric on which the base coating is completed. visible coationg). This uses a coating method such as a visible coating of a general polyester urethane coating.

이러한 제 1, 2공정은 종래 기술의 폴리에스터 우레탄 코팅에서도 해왔던 일반적인 방법이며, 종래에는 이러한 1,2차 공정만을 실시하게 되면 원하는 방수, 발수 특성을 얻을 수 없으므로 이러한 코팅공정을 여러번 거쳐 방수, 발수 특성을 구현하도록 할 수도 있지만 그러면 청 원단의 섬유특성이 변하여 질감을 잃게 되었던바, 본 발명에서는 제 1,2공정을 거친 청 원단에 제 3공정에 의한 코팅만을 실시하게 되면 청 원단의 특성은 변화시키지 않고 원하는 방수, 발수 특성을 구현할 수 있는 것으로, 제 3공정으로서 청 원단에 스티렌 브타디엔 계통의 공중합 라텍스에 첨가물질을 넣은 코팅제를 얹은 나이프 코팅방법으로 실시하여 본 발명의 목적이 실현되는 것이다.These first and second processes are a general method that has been performed in the polyester urethane coating of the prior art, and if only the first and second processes are conventionally performed, the desired waterproof and water repellent properties cannot be obtained. The water-repellent properties may be implemented, but then the fiber properties of the blue fabric are changed to lose the texture. In the present invention, only the coating by the third process is applied to the blue fabric which has been subjected to the first and second processes, The desired waterproof and water-repellent properties can be realized without changing, and the third step is to realize the object of the present invention by performing a knife coating method in which a blue woven fabric is coated with a coating material containing an additive material in a styrene butadiene-based copolymerized latex. .

이때, 스티렌 부타디엔 고무는 스티렌과 부타디엔을 혼성 중합하여 만든 합성고무로서, 자동차 타이어를 비롯하여 가장 많이 사용되는 일반적인 상품으로 1930년대 이후 독일에서 연구, 공업화되어 부나-S라는 상품명으로 시판되었다.In this case, styrene butadiene rubber is a synthetic rubber made by hybridization of styrene and butadiene, and is the most commonly used general product including automobile tires. Since its research and industrialization in Germany since the 1930s, it has been marketed under the trade name Buna-S.

여기에는 중합법에 따라 유화중합, 융합중합, 괴상중합, 에멀젼화중합 등의 여러공정이 있는데, 본 발명에서는 이중 라이칼중합 개시제를 사용한 에멀젼화중합법으로 제조하였다.There are various processes such as emulsion polymerization, fusion polymerization, block polymerization, and emulsion polymerization according to the polymerization method. In the present invention, an emulsion polymerization method using a double lycal polymerization initiator is prepared.

중합온도는 5℃(저온중합)이며, 그 조성은 스티렌 약 25wt%, 부타디엔 약 75wt%(부타디엔 결합양식은 시스-1, 4결합13%, 트렌스-1, 4결합 69%, 트렌스-1, 2결합18%)이다.The polymerization temperature is 5 ° C. (low temperature polymerization), and its composition is about 25 wt% of styrene and about 75wt% of butadiene (butadiene bonding mode is cis-1, 4 bond 13%, trans-1, 4 bond 69%, trans-1, 2 bonds 18%).

또한, 상기에서 제조된 에멀젼화라디칼 중합제 43wt%에 물 54.2wt%와, 중합하는 화합물의 저장 안정성을 위해 중합금지제인 카테콜(화학식 : C6H6(OH)2)을 0.1wt% 넣어 안정제로 사용하였다.In addition, 54 wt% of water and 43 wt% of the emulsified radical polymerizer prepared above were added 0.1 wt% of catechol (Chemical Formula: C 6 H 6 (OH) 2 ), which is a polymerization inhibitor, for storage stability of the polymerized compound. Used as stabilizer.

또한, 여기에 셀룰로오즈 유도체(eg. EHEC) 등과 같은 수용성 폴리 사카리아드계를 0.2wt% 첨가하여 중점제로 사용했는데 셀룰로오즈 분자는 무수 글루코오즈 단량체의 사슬로 이루어져 있으며, 이러한 단량체의 숫자는 점도에 매우 중요한 역할을 한다. 이때 무수 글로코오즈내에 있는 세개의 수산화기는 아킬 또는 수산화알킬의 유도체로 변형될 수 있으며, 이것은 용해성, 표면활성, 화학 반응성, 화학 저항성, 효소 저항성 등과 같은 화학적 특성을 셀룰로오즈 에테르에 부여하게 되고, 폴리 사카라이드계 중점제는 여러분야에 활용하고 있으며 제품의 증점효과 및 재료분리 방지성 등의 특성이 있다.In addition, 0.2 wt% of water-soluble polysaccharides such as cellulose derivatives (eg, EHEC) were added as a middle agent, and the cellulose molecules were composed of chains of anhydrous glucose monomers, and the number of such monomers was very important for viscosity. Play a role. The three hydroxyl groups in the anhydrous glocose can then be modified with derivatives of alkyl or alkyl hydroxides, which impart chemical properties to the cellulose ether such as solubility, surface activity, chemical reactivity, chemical resistance, enzyme resistance, and the like. The saccharide-based emulsifiers are used in all of you and have characteristics such as thickening effect and material separation prevention.

마지막으로 물에 잘 녹지는 않으나 내부에 넓은 표면적을 가지며 화학적 활성이 없는 방습제 실리카겔(SiO2)을 2.5wt% 넣어 코팅제를 완성하게 된다.Finally, 2.5 wt% of silica gel (SiO 2 ), which is not soluble in water but has a large surface area and has no chemical activity, is used to complete the coating.

즉, 스티렌 부타디엔 계통의 공중합 라텍스(이하 공중합체)는 투습성이 낮고 내수성 발수성이 훌륭하여 폴리에틸렌 라미네이트 종이 정도의 방습성 및 광택성을 얻을 수 있으며, 내블록킹성도 훌륭하여 유연성있는 피막을 형성할 수 있고 난해성이 좋아 오래가는 특성이 있는 반면 이러한 공중합체만으로는 코팅제로 사용할 수 없으므로 여기에 물을 희석하여 코팅제를 조성하게 된 것인데, 코팅제로 활용하기 위해서는 물의 함량이 적어도 공중합체보다는 많아야 하며, 그 반대가 되면 점도가 너무 강해 원활한 코팅을 수행할 수 없을 것이다. 또한 방습제, 중점제, 안정제 등의 첨가제도 미량 첨가할 수 있다.In other words, styrene butadiene-based copolymer latex (hereinafter referred to as copolymer) has low moisture permeability and excellent water repellency and water repellency and glossiness of polyethylene laminate paper, and has excellent blocking resistance and can form a flexible film with difficulty. While this has long lasting properties, these copolymers alone cannot be used as a coating agent, so that the coating is formed by diluting water. To use the coating agent, the water content must be at least higher than that of the copolymer, and vice versa. Is too strong to be able to perform a smooth coating. In addition, a small amount of additives such as a desiccant, a middle agent, and a stabilizer can be added.

따라서, 상기한 모든 여건을 고려하여 아래와 같이 공중합체를 포함한 코팅제의 최적의 성분함량을 얻을 수 있었다.Therefore, in consideration of all the above conditions, it was possible to obtain the optimum component content of the coating including the copolymer as follows.

Water Soluble ---------- Mixes well with water. When the coating agent composed of the above-mentioned ingredients is placed on the blue fabric where the second visible coating is completed, and the third coating is performed by the knife coating method. According to the characteristics of the copolymer, which is the main component of the coating agent, a flexible film is formed on the surface of the blue fabric, so that the waterproof and water repellent properties can be realized, and the blue fabric of excellent texture can be obtained without changing the characteristics of the blue fabric. .

상기와 같이 가공 처리되어 제조되는 본 발명은 천연섬유 인 청 원단 표면에 1,2차에 걸쳐 일반적인 통상의 코팅을 실시한 후 그 위에 스치렌 부타지엔 계통의 공중합 라텍스 코팅을 실시하므로써 청 원단 섬유의 본래의 특성은 변질되지 않고 유지되면서 방수, 발수의 효과를 얻을 수 있다.The present invention, which is processed and manufactured as described above, performs general conventional coating on the surface of natural fabric, which is natural fiber, for 1 to 2 times, and then performs copolymerization latex coating of styrene butadiene system on the surface of natural fabric. Its properties are maintained without deterioration, and the waterproof and water repellent effect can be obtained.

따라서, 청 원단 섬유의 특유의 멋과 특성을 살리면서 추위와 물과 바람을 차단하여 보온을 이루면서 탁월한 방수 효과가 있기 때문에 청바지 청자켓등의 면종류의 옷을 동절기와 우천시에 따뜻하게 입을 수 있음은 몰론 스키복이나 스노우보드복과 같은 스포츠복이나 레인기어와 같은 특수 방수용 의류에 적용할 수 있으며, 젖지 않는 면으로 된 가방, 모자, 신발 등 생활제품에도 폭넓게 적용될 수 있는 유용한 효과가 있는 것이다.Therefore, by utilizing the unique fashion and characteristics of blue fabric fibers, it is possible to keep warm by blocking cold, water, and wind, and to maintain warmth in winter and rainy weather.
