Description

섬세 다공질 피복포(被覆布)의 제조방법Manufacturing method of fine porous coating cloth

본 발명은 천연피혁의 뒷면 표피와 비슷한 피복포(被覆布)를 얻기 위하여 부직포(不織布), 직물(織物), 편물, 메리야스 등의 기포위에 열가소성 합성수지발포(發泡)층을 형성하고 열보유체에 의하여 이형지에 합성수지층의 표피를 제거하여 섬세다공질 피복포를 제조하는 방법에 관한 것이다.The present invention is to form a thermoplastic synthetic resin foam layer on the foam of non-woven fabric (woven fabric), woven fabric, knitted fabric, Mary's, etc. in order to obtain a cover cloth similar to the back skin of the natural leather and heat retention The present invention relates to a method for producing a fine porous coating fabric by removing the skin of the synthetic resin layer on the release paper.

종래에는 천연피혁의 뒷면표피같은 인조피복포를 얻기 위하여 직물류의 기포위에 폴리우레탄, 풀리아미드와 같은 합성수지 조성물을 도포 또는 딥핑하여 피복된 포(布)를 기계적으로 절삭 연마하는 방법에 의해 제조하거나 피복포에 단소(短小)섬유를 균일하게 식모(

毛)하는 방법으로 제조되어 왔다. 그러나 공지의 절삭연마방식은 기술적으로 대단한 숙련도를 요할뿐 아니라 절삭에 의한 피복포기 기모(起毛)의 상태가 균일성이 없으며, 식모방법은 기모의 상태는 균일성은 있으나 사용상 마찰에 의한 단소섬유의 탈탁 관계로 두가지 방식 공히 문제점이 있었다.Conventionally, in order to obtain artificial coatings such as the back skin of natural leather, a synthetic fabric composition such as polyurethane or pulleyamide is applied or dipped onto the cloth of fabrics by mechanical cutting and polishing of the coated fabrics. Evenly weave sweet soybean fiber in cloth
Figure kpo00001
It has been produced by the method of fuzzing. However, the known cutting and polishing method requires not only a great technical skill, but also a uniform state of raising the coated aeration by cutting. There was a problem with both methods.

본 발명은 공지의 방식에서 기술적으로 어려운 문제점과는 전연 관계없이 새로운 방법에 관한 것으로서 기모포위에 열가소성 합성수지 조성물을 도포하고, 발포하여 스폰지층(이하 기모 피복포라함)을 얻고, 이 기모 피복포의 표피부를 연화용융(軟化溶融)온도(200℃)로 가열할 열보유체(保有體)를 이용하여 이 열보유 체표면에 종이를 장착한 다음 이 종이저면(低面)의 온도가 200℃이내가 되도록 유지하면서 열보유체를 가열함과 동시에 상기 기모피복포와 상기 열보유체에 장착된 종이저면을 순간적으로 압착 및 분리하여 상기 기모피복포의 합성수지 발포층의 표피막이 종이쪽에 흡착되도록 함으로서 발포층의 표피막이 제거되어 기모피복포의 합성수지 발포층의 미세한 다공(多孔)구조가 그대로 노출되어 기모포의 단섬유군의 조밀한 형상과 함께 천연피혁의 뒷면표피와 같은 형상으로 유연한 감축을 주는 섬세한 다공질 피복포를 얻게 된다.The present invention relates to a new method irrespective of the technically difficult problems in a known manner, by applying a thermoplastic synthetic resin composition on a raised fabric and foaming to obtain a sponge layer (hereinafter referred to as brushed coating fabric), A paper is placed on the surface of the heat-retaining body by using a heat-retaining medium to heat the skin to the softening melting temperature (200 ° C), and then the temperature of the bottom of the paper is 200 ° C. While keeping the heat retainer within, while simultaneously compressing and separating the brushed cloth and the bottom of the paper mounted on the heat retainer, the outer film of the synthetic resin foam layer of the brushed cloth is adsorbed onto the paper. The epidermis of the layer is removed, and the fine porous structure of the synthetic resin foam layer of the brushed cloth is exposed as it is, with the dense shape of the short fiber group of the brushed cloth. It is obtained for coated fine porous fabric to the flexible cut in the same shape as the back skin of soft leather.

본 발명의 방법에 따른 기포로서는 직물, 편물, 부직포등 직물을 형성하는 섬유재료로 면, 레이온, 모, 초자, 폴리에스텔, 폴리아미드 등의 합성섬유 단사 또는 혼방사이며, 조직으로는 평직, 능직, 주자직 등이 사용되며, 메리야스직물로서는 편직 또는 양면 편직물이 사용되고, 이외에도 어떠한 기포이든 본 발명에서 기모포로서 사용될 수 있다. 기모피복에 합성수지 발포층을 형성하는 물질로는 폴리염화비닐, 폴리우레탄, 나이롱 등 열가소성 합성수지계 물질로서 형성되나, 그 가운데 폴리염화비닐 페이스트(paste)수지가 본 발명의 열보유체에 의한 처리가공에 있어 적합한 재료이다.The foam according to the method of the present invention is a fiber material for forming a woven fabric such as woven fabric, knitted fabric, nonwoven fabric, and the like, or a single yarn or mixed yarn of synthetic fibers such as cotton, rayon, wool, ceramic, polyester, polyamide, and the like. Runner weaving and the like are used, and a knitted or double-sided knit fabric is used as the Maryas fabric, and any other bubble can be used as the raising fabric in the present invention. The material for forming the synthetic resin foam layer on the brushed coating is formed as a thermoplastic synthetic resin-based material such as polyvinyl chloride, polyurethane, or nylon, and among them, polyvinyl chloride paste resin is processed by the heat retention material of the present invention. Is a suitable material.

기모포의 피복, 발포층을 얻기 위하여는 폴리염화비닐 페이스트 조성물을 기모포에 직접 도포하는 방법과 이형지를 이용하여 이형지 위에 합성수지를 도포하여 기모포와 접합, 건조 및 발포하여 이형지를 박리하는 방법이 있다. 이들 기모포피복발포 방법은 종래에 기술로서 공지되어 있다. 이렇게 하여 얻어진 기모피복발포를 상기한 열보유체에 장착된 종이면과 접합함과 동시에 가열하여 발포층의 표피막이 종이에 흡착되어 제거되게 한다.In order to obtain a covering and foam layer of the raising fabric, there are a method of directly applying a polyvinyl chloride paste composition to the raising fabric and a method of applying a synthetic resin onto the release paper using a release paper, and then peeling off the release paper by bonding, drying and foaming with the raising fabric. . These methods of raising coated wool are known in the art. The brushed coating foam thus obtained is bonded to the paper surface mounted on the above-mentioned heat retainer and heated at the same time so that the skin layer of the foam layer is adsorbed and removed from the paper.

열) a hot plate, a super magnetic plate, and the like can be used. In this case, when the heat-retaining material is heated to 200 ° C or more, which is a softening melting temperature of the polyvinyl chloride foam layer, the foamed pores are melted and compressed so that flexibility is lost. In this state, the foam layer skin film should be pressed immediately.

이와같이 순간 압착시키면 상기한 바와같이 기모피복포의 열보유체상의 종이에 흡착되어 발포층으로부터 쉽게 제거되므로 기모피복포의 표면에 미세한 다공질표면을 형성하게 되어 본 발명의 섬세한 다공질 피복포를 제조하게 된다.As such, when the instantaneous compression is carried out, it is adsorbed on the paper on the heat-retaining paper of the brushed cloth and is easily removed from the foam layer, thereby forming a fine porous surface on the surface of the brushed cloth, thereby producing the delicate porous coated cloth of the present invention. .
