본 발명에 대해 첨부한 도면을 참조하여 바람직한 실시예를 설명하면 다음과 같으며, 이와 같은 상세한 설명을 통해서 본 발명의 목적과 구성 및 그에 따른 특징들을 보다 잘 이해할 수 있게 될 것이다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. The present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
본 발명의 실시예에 의한 기능성 인조피혁의 제조방법은 도 1에 나타낸 바와 같이, 통기성을 갖는 베이스 원단에 기모(起毛) 처리를 행한다(S1).In the manufacturing method of the functional artificial leather according to the embodiment of the present invention, as shown in Fig. 1, the base fabric having air permeability is subjected to brushing treatment (S1).
이때, 상기 베이스 원단으로는 트리코트(tricot) 또는 니트(knit)의 직물을 사용함이 바람직하다.At this time, it is preferable to use a tricot or knit fabric as the base fabric.
이렇게 베이스 원단에 기모 처리를 행하는 이유는 원단 생지를 그대로 사용하는 경우 광택이 너무 세고 터치감이 떨어지게 되는데, 이를 방지하기 위함이다.The reason for brushing the base fabric is that the gloss is too strong and the touch is inferior when the dough is used as it is, to prevent this.
더욱 바람직하게는, 베이스 원단에 대해 110~140℃의 온도조건에서 50~60분 동안 염색 및 건조 처리한 이후에, 기모 처리를 수행하는 것이 좋다.More preferably, after the dyeing and drying treatment for 50 to 60 minutes at a temperature condition of 110 ~ 140 ℃ for the base fabric, it is good to perform a brushing treatment.
즉, 베이스 원단에는 비결정영역의 불순물이 많은데 염색과 함께 열처리를 행함에 따라 원단으로부터 불순물을 제거할 수 있으면서 염색을 통해 색상을 고르게 표출할 수 있음은 물론 원단의 수축작용으로 형태를 완성해갈 수 있다.In other words, the base fabric has a large amount of impurities in the amorphous region, and as the heat treatment is performed along with the dyeing, the impurities can be removed from the fabric, and the color can be expressed evenly through the dyeing, and the form can be completed by the shrinking action of the fabric. .
상기와 같이, 기모 처리가 이루어진 베이스 원단의 기모처리면 상에 폴리우레탄 카보네이트 수지와 용제가 혼합된 코팅조성물을 전체적으로 코팅 처리하여 피혁코팅층을 형성하되, 도 2에서 보여주는 바와 같은 도트(dot)형 요철(11)을 갖는 도트롤러(10)를 통해 도트방식으로 도포하여 코팅함으로써 베이스 원단이 가지는 통기성을 유지하면서 코팅 처리되게 한다(S2).As described above, by coating the coating composition of the polyurethane carbonate resin and the solvent mixed on the brushed surface of the base fabric subjected to brushing treatment as a whole to form a leather coating layer, as shown in Figure 2 (dot) irregularities The coating is applied by coating in a dot method through the
이때, 코팅조성물은 폴리우레탄 카보네이트 수지 100중량부에 대해 용제 70중량부로 이루어진 것을 사용하되, 상기 용제는 기모가 일어나는 현상을 방지할 수 있도록 디메틸포름아미드와 메틸에틸케톤이 중량비 또는 부피비 6:4로 혼합된 것을 사용함이 바람직하며, 50~150g/㎡의 투입량으로 베이스 원단 측에 투입함으로써 베이스 원단 상에 피혁코팅층이 형성되게 한다.At this time, the coating composition is made of 70 parts by weight of solvent based on 100 parts by weight of polyurethane carbonate resin, the solvent is dimethylformamide and methyl ethyl ketone in a weight ratio or volume ratio of 6: 4 to prevent napping occurs It is preferable to use a mixed one, and the leather coating layer is formed on the base fabric by injecting to the base fabric side with an input amount of 50 ~ 150g / ㎡.
여기서, 베이스 원단 상에 폴리우레탄 카보네이트 수지와 용제가 혼합된 코팅조성물로 형성되는 피혁코팅층은 피혁의 느낌을 제공하면서 가수분해성에 의한 변형을 방지하는 내가수분해성을 부여할 수 있으며, 내가수분해성으로 베이스 원단 측의 기모가 일어나는 현상 또한 방지하는 기능을 하게 된다.Here, the leather coating layer formed of a coating composition mixed with a polyurethane carbonate resin and a solvent on the base fabric can impart hydrolysis resistance to prevent deformation due to hydrolysis while providing a feeling of leather. It also serves to prevent the occurrence of napping on the base fabric side.
덧붙여, 상기 도트롤러(10)는 표면에 도트형 요철(11)이 다수 형성되는데, 이 도트형 요철(11)에 코팅조성물을 묻혀 기모 처리된 베이스 원단 측에 도트형 롤러코팅을 실시하도록 구비되며, 이를 통해 육안으로 확인되지 않지만 트리코트(tricot) 또는 니트(knit)의 베이스 원단이 가지는 통기성을 유지할 수 있는 피혁코팅층을 베이스 원단의 전체 면에 걸쳐 고르게 입힐 수 있게 된다.In addition, the
이후, 베이스 원단에 피혁코팅층이 형성된 결과물에 대해 친즈(chinz) 가공 처리한다(S3).Subsequently, the resultant of which the leather coating layer is formed on the base fabric is subjected to Chinz processing (S3).
이때, 친즈(chinz) 가공은 베이스 원단의 피혁코팅층이 형성된 부분으로 열을 가한 다림질을 행하는 것을 의미하며, 본 발명에서는 폴리우레탄 카보네이트 소재의 피혁코팅층의 물성을 고려하여 110~140℃의 온도조건에서 친즈 가공함이 바람직하다.At this time, the Chinz processing means to perform ironing by applying heat to the part where the leather coating layer of the base fabric is formed, in the present invention in consideration of the physical properties of the leather coating layer of polyurethane carbonate at a temperature of 110 ~ 140 ℃ Chinze processing is preferred.
이 열을 가한 다림질의 친즈 가공으로는 피혁코팅층 내에 형성된 미세한 공극의 크기를 줄여주는 작용을 하게 되며, 이에 의해 이어지는 축광 패턴의 후속공정 처리시 축광처리물이 피혁코팅층 상에 자연스럽게 잘 묻어나게 되는 등 축광 처리효율을 높일 수 있게 된다.The ironing chin processing of this heat acts to reduce the size of the fine pores formed in the leather coating layer, thereby causing the phosphorescent material to be naturally buried on the leather coating layer during the subsequent processing of the subsequent photoluminescent pattern. Photoluminescent treatment efficiency can be improved.
이어서, 상기한 친즈 가공까지 처리된 결과물 상에 폴리우레탄 카보네이트 수지와 축광안료가 혼합된 축광처리물을 축광패턴롤러를 이용하여 축광패턴 형성작업을 행한다(S4).Subsequently, a photoluminescent pattern forming operation is performed using a photoluminescent pattern roller on the photoluminescent processed material in which the polyurethane carbonate resin and the photoluminescent pigment are mixed on the resultant processed up to the above-mentioned machining (S4).
이때, 축광처리물은 폴리우레탄 카보네이트 수지 90~98중량%와 축광안료 2~10중량%의 혼합 조성으로 이루어진 것을 사용함이 바람직하며, 이를 통해서는 축광처리물의 부착성 및 축광 처리효율을 높일 수 있게 된다.In this case, the photoluminescent material is preferably made of a mixture composition of 90 to 98% by weight of polyurethane carbonate resin and 2 to 10% by weight of the photoluminescent pigment, thereby improving the adhesion and photoluminescent treatment efficiency of the photoluminescent treatment. do.
여기서, 상기 축광패턴 형성작업을 위한 축광패턴롤러는 표면 전체에 걸쳐 패턴이 형성된 것이 아니라 상징성을 갖는 로고나 문자 등의 디자인을 본 발명에 의해 제조되는 인조피혁 상에 표출할 수 있도록 한 것으로서, 일 예로 도 3의 예시에서와 같은 축광패턴을 형성시킬 수 있도록 표면 일부에 축광패턴 형성용 요철이 구비된다 할 것이다.Here, the photoluminescent pattern roller for forming the photoluminescent pattern is not a pattern is formed over the entire surface, so that a design such as a logo or a letter having a symbolism can be expressed on the artificial leather produced by the present invention, for example 3 will be provided with the concave-convex for forming the photoluminescent pattern to form a photoluminescent pattern as in the example of FIG.
마지막으로, 상기한 축광 처리까지 마친 결과물에 대해 엠보롤러를 이용하여 전체적인 무늬패턴을 엠보 성형함으로써 기능성 인조피혁의 제조를 마무리한다(S5).Finally, the embossing of the entire pattern pattern using the embossing roller is finished to the above photoluminescent treatment to finish the manufacture of the functional artificial leather (S5).
이때, 엠보 성형은 제조되는 기능성 인조피혁의 결과물에 광택이 너무 저하되는 것을 방지할 수 있도록 120~160℃의 온도조건과, 내마모성을 구비할 수 있도록 3~10kg/㎠의 압력조건에서 수행함이 바람직하다.At this time, the embossing is preferably carried out at a temperature condition of 120 ~ 160 ℃ and a pressure condition of 3 ~ 10kg / ㎠ to provide abrasion resistance to prevent the gloss is too lowered to the result of the functional artificial leather to be manufactured Do.
여기서, 상기한 엠보롤러는 그 표면에 도 4a 및 도 4b에서 보여주는 일 실시예와 같은 무늬패턴을 결과물의 전체에 걸쳐 엠보 성형할 수 있도록 엠보싱 처리되며, 피혁의 느낌을 살릴 수 있는 무늬패턴 등을 비롯하여 아주 다양한 형태의 무늬패턴을 형성시킬 수 있다 할 것이다.Here, the embossing roller is embossed to emboss the entire pattern of the pattern pattern as shown in the embodiment shown in Figures 4a and 4b on the surface, such as a pattern pattern that can utilize the feeling of leather Of course, it is possible to form a wide variety of pattern patterns.
이상에서 설명한 실시예는 본 발명의 바람직한 실시예를 설명한 것에 불과하고 이러한 실시예에 한정되는 것은 아니며, 본 발명의 기술적 사상과 특허청구범위 내에서 이 기술분야의 당업자에 의하여 다양한 수정과 변형 또는 치환이 이루어질 수 있다 할 것이며, 이는 본 발명의 기술적 범위에 속한다 할 것이다.The embodiments described above are merely illustrative of the preferred embodiments of the present invention and are not limited to these embodiments, and various modifications, changes or substitutions may be made by those skilled in the art within the spirit and scope of the present invention.
