이염방지성 및 유연성이 우수한 합성피혁의 제조방법.{Method of manufacturing synthetic leather with excellent anti-dye migration and flexibility}{Method of manufacturing synthetic leather with excellent anti-dye migration and flexibility}

본 발명은 이염방지성 및 유연성이 우수한 합성피혁에 관한 것으로서 보다 구체적으로는 이염방지성 및 유연성이 우수하여 휴대폰, 노트북 등과 같은 전자제품용 케이스 소재등에 유용한 합성피혁에 관한 것이다.
The present invention relates to a synthetic leather having excellent stain prevention and flexibility, and more particularly, to a synthetic leather which is useful for a case material for an electronic product such as a mobile phone or a notebook due to its excellent stain prevention and flexibility.

최근 공급이 한정되고 가격이 비싼 천연피혁을 대신하여 이와 외관 및 촉감이 유사하게 제조된 합성피혁이 전자제품용 케이스 소재, 의류용 소재 및 생활 장신구용 소재 등으로 많이 사용되고 있다.In recent years, synthetic leather, which is manufactured in a similar way in appearance and touch in place of natural leather with limited supply and high price, is used as a case material for electronic products, a material for clothing, and a life accessory.

합성피혁은 표면에 짧고 균일한 파일이 조밀하게 형성된 누박조 타입과 표면에 긴 파일이 형성된 스웨드 타입으로 구분 되어진다.Synthetic leather is divided into the type of nucleus dense with short and uniform pile on the surface and suede type with long pile on the surface.

종래 합성피혁은 천연피혁과 비슷한 외관 및 촉감을 나타내지만, 이염방지성과 유연성(꺽임성)이 나빠서 휴대폰, 노트북 등의 전자제품 케이스용 소재 등으로 사용하기에는 어려움이 많았다.Conventional synthetic leather exhibits a similar appearance and feel to natural leather, but it is difficult to use as a material for electronic product cases such as mobile phones and laptops due to poor dye transfer prevention and flexibility.

합성피혁을 제조하는 종래 방법으로는 폴리에스테르 편물 폴리우레탄 수지 용액내에 침지하여 상기 폴리에스테르 편물내에 폴리우레탄 수지를 함침시킨 다음, 폴리우레탄 수지가 함침된 폴리에스테르 편물을 물속에 침지시켜 폴리에스테르 편물에 함침된 폴리우레탄 수지를 응고시킨 다음, 분산염료로 염색하여 합성피혁을 제조하는 방법이 사용되어 왔다.Conventional methods for producing synthetic leather are immersed in a polyester knitted polyurethane resin solution to impregnate a polyurethane resin in the polyester knitted fabric, and then a polyester knitted fabric impregnated with a polyurethane resin is immersed in water to give a polyester knitted fabric. A method of producing synthetic leather by solidifying the impregnated polyurethane resin and then dyeing with a disperse dye has been used.

또 다른 종래방법으로는 폴리에스테르 편물을 분산염료로 염색한 후 상기 폴리에스테르 편물내에 폴리우레탄 수지를 함침시킨 다음, 폴리우레탄 수지가 함침된 폴리에스테르 편물을 물속에 침지시켜 폴리우레탄 수지를 응고시킨 다음 버핑기 또는 기모기로 표면을 정리하여 스웨드조 합성피혁을 제조하는 방법이 사용되어 왔다.Another conventional method is to dye a polyester knit fabric with a disperse dye, and then impregnate a polyurethane resin into the polyester knit fabric, and then immerse the polyester knit fabric impregnated with the polyurethane resin in water to solidify the polyurethane resin. A method of preparing suede-like synthetic leather by arranging the surface with a buffing machine or a brush has been used.

그러나, 상기의 종래방법으로 제조된 합성피혁을 전자제품용 케이스 소재 등으로 사용시 염색된 분산염료가 전자제품으로 이염되어 전자제품을 오염시키거나 인접한 다른 원단을 오염시키는 문제가 발생하였고, 유연성(꺽임성)도 부족한 문제도 발생 되었다.
However, when the synthetic leather manufactured by the conventional method is used as a case material for electronic products, the dyed disperse dye is transferred to the electronic products, which contaminates the electronic products or contaminates other adjacent fabrics. There was also a lack of problems.

본 발명의 과제는 상기 종래의 문제점을 해결할 수 있도록 이염방지성이 우수함과 동시에 유연성(꺽임성)도 뛰어난 합성피혁을 제조하는 방법을 제공하는 것이다.SUMMARY OF THE INVENTION An object of the present invention is to provide a method for producing a synthetic leather which is excellent in anti-staining resistance and also excellent in flexibility (twistability) to solve the conventional problems.

이와 같은 과제를 달성하기 위해서, 본 발명에서는 합성피혁을 분산염료로 염색하는 대신에 합성피혁에 함침되는 폴리우레탄 수지 내에 안료를 첨가함과 동시에 안료를 포함하는 바인더 조성물을 합성피혁의 일면에 프린팅하여 이염방지성을 향상시키는 것을 특징으로 한다.In order to achieve the above object, in the present invention, instead of dyeing the synthetic leather with a disperse dye, the pigment is added to the polyurethane resin impregnated in the synthetic leather and at the same time by printing a binder composition containing the pigment on one side of the synthetic leather It is characterized by improving the dye transfer prevention property.

또한, 본 발명에서는 합성피혁의 유연성(꺽임성)을 향상시키기 위해서 폴리우레탄 함침공정 이전에 폴리에스테르 편물 일면에 먼저 폴리비닐알코올 수지층을 형성한 다음, 폴리우레탄 함침공정을 실시하고, 이후 폴리우레탄 수지의 응고공정에서 상기 폴리비닐알코올 수지층을 용출함으로써 합성수지의 일면에 공극들을 형성시켜준다.
In addition, in the present invention, in order to improve the flexibility (flexibility) of the synthetic leather, the polyvinyl alcohol resin layer is first formed on one surface of the polyester knitted fabric before the polyurethane impregnation process, and then the polyurethane impregnation process is performed, and then the polyurethane In the coagulation step of the resin, the polyvinyl alcohol resin layer is eluted to form voids on one surface of the synthetic resin.

본 발명으로 제조된 합성피혁은 염색 대신에 안료가 함침 및 프린팅되어 있어서 이염방지성이 우수함과 동시에 폴리비닐알코올 수지층이 용출된 부분에 미세 공극들이 형성되어 있어서 촉감 및 유연성(꺽임성)도 양호하다.Synthetic leather prepared according to the present invention is impregnated and printed instead of dyeing, excellent in dyeing prevention and at the same time fine pores are formed in the part where the polyvinyl alcohol resin layer is eluted, so the touch and flexibility (kinkability) is also good. Do.

그로 인해 본 발명으로 제조된 합성피혁은 휴대폰, 노트북 등과 같은 전자제품용 케이스 소재, 신발용 소재, 의류용 소재 등에 유용하다.
Therefore, the synthetic leather produced by the present invention is useful for case materials for electronic products such as mobile phones, notebook computers, shoes materials, clothing materials, and the like.
