슬림성과 고탄성을 가지는 자동차 시트 제조방법{Method for manufacturing automobile seats with slimness and high elasticity}Method for manufacturing automobile seats with slimness and high elasticity

본 발명은 슬림성과 고탄성을 가지는 자동차 시트 제조방법에 관한 것으로, 보다 상세하게는 통기성, 쿠션감, 저수축, 난연성, 슬림성 및 고탄성의 기능을 가지며 환경에 무해한 소재로 이루어지는 슬림성과 고탄성을 가지는 자동차 시트 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a car seat having slimness and high elasticity, and more particularly, a car having slimness and high elasticity made of a material harmless to the environment and having functions of breathability, cushioning, low shrinkage, flame retardancy, slimness and high elasticity. It relates to a method for manufacturing a sheet.

자동차용 내장부품은 화재나 전복 등과 같은 돌발사고에 대비하여 탑승자를 보호하고, 쾌적한 실내 분위기를 제공함으로써 안전운행을 유도하는 구성이다. 이러한 자동차용 내장부품 중 자동차 시트의 경우, 소재 및 제조 기술에 따라 높은 수준의 감성과 심미적 기능을 부여함으로써 탑승자의 품위와 가치를 증가시킬 수 있다. 이를 위하여 자동차 시트는 고도의 난연성, 내구성, 높은 수준의 감성 및 심미적 기능을 만족하는 다양한 소재로 구성된다. 자동차 시트에 적용되는 소재 중 폴리우레탄(polyurethane, PU)은 보온성, 안락성 및 소음저감에 유리하고 저렴하다는 장점을 가지고 있어 현재 많은 자동차에 적용되고 있다.Automotive interior parts are a configuration that induces safe driving by protecting occupants in preparation for unexpected accidents such as fire or rollover, and providing a pleasant indoor atmosphere. Among these interior parts for automobiles, in the case of automobile seats, the dignity and value of occupants can be increased by providing high-level emotional and aesthetic functions according to materials and manufacturing technologies. To this end, automobile seats are composed of various materials that satisfy high flame retardancy, durability, high level of sensitivity, and aesthetic functions. Among the materials applied to automobile seats, polyurethane (PU) is advantageous for heat retention, comfort and noise reduction and has the advantage of being inexpensive, so it is currently being applied to many automobiles.

이러한 폴리우레탄 소재로 이루어진 종래기술은 '대한민국특허청 등록특허 제10-1855924호 습기 경화형 폴리우레탄 핫멜트를 이용한 자동차 시트 제조 장치 및 방법'과 같이, 공급되는 원단에 제1접착제를 도포하는 단계; 상기 제1접착제가 도포된 원단에 공급되는 폴리우레탄 폼을 제1압착하는 단계; 스크루 롤러로 펼쳐져 공급되는 백킹클로스에 제2접착제를 도포하는 단계; 및 압착된 폴리우레탄 폼에 상기 제2접착제가 도포된 백킹클로스를 제2압착하여 자동차 시트를 제조하는 단계를 포함하는 기술이 알려져 있다.The prior art made of such a polyurethane material includes the steps of applying a first adhesive to the supplied fabric, such as 'Korea Patent Office Registration No. 10-1855924 Apparatus and method for manufacturing an automobile seat using a moisture-curing polyurethane hot melt'; first compressing the polyurethane foam supplied to the fabric to which the first adhesive is applied; applying a second adhesive to a backing cloth that is spread and supplied with a screw roller; And there is known a technique comprising the step of manufacturing a car seat by second pressing the second adhesive is applied to the compressed polyurethane foam backing cloth.

하지만, 이러한 폴리우레탄 소재의 자동차 시트는 냄새나 변색 등이 발생할 수 있으며, 재활용이 어려워 환경에 유해한 소재에 해당한다. 이에, 최근에는 폴리우레탄 소재를 장기간 사용시 발생되는 꺼짐현상에 대처하고, 통기성 및 안락감을 동시에 만족시키기 위한 폴리우레탄 발포체(polyurethane foam)에 대한 연구가 이루어지고 있다. 이러한 폴리우레탄 발포체를 이용한 자동차 시트 제조의 경우, 불꽃으로 태우는 플레임 라미네이션(flame lamination) 방식을 채택하고 있으며, 이는 폴리우레탄 발포체의 낮은 접착성과 생산성에 기인한다. 하지만 플레임 라미네이션 방식의 경우 공정 중 다량의 미세먼지와 함께 환경 유해가스가 발생하는 등 환경적으로 많은 문제점을 유발하기 때문에 이를 대체할 소재가 시급한 실정이다.However, such a polyurethane car seat may cause odor or discoloration, and it is difficult to recycle, so it is a material harmful to the environment. Accordingly, recently, studies on polyurethane foam have been conducted to cope with the off phenomenon that occurs when a polyurethane material is used for a long period of time, and to satisfy both breathability and comfort. In the case of automobile seat manufacturing using such a polyurethane foam, a flame lamination method burned with a flame is adopted, which is due to the low adhesion and productivity of the polyurethane foam. However, in the case of the flame lamination method, there is an urgent need for a replacement material because it causes many environmental problems, such as a large amount of fine dust and environmental harmful gases generated during the process.

Since the accompanying drawings are merely examples shown in order to explain the technical idea of the present invention in more detail, the technical idea of the present invention is not limited to the form of the accompanying drawings.

현재 자동차 시트로 사용되는 것은 단열성이 우수한 폴리우레탄 단일 발포체가 널리 사용되고 있으나, 기능 부여의 한계, 친환경성 부족, 재활용 불가, 결로 및 취화 등의 문제가 제기되고 있어서 다양한 대체 및 보완 수단이 연구되고 있다. 최근에는 단일 소재나 층으로 구성된 단순한 형상의 자동차 시트로부터 벗어나 신소재를 적층 활용하여 통기성이나 승차감을 크게 높이면서 탑승자의 체압을 효과적으로 분산시켜 장시간 운전에도 피로도를 크게 느끼지 않게 하며, 사고시 안전성도 높이는 자동차 시트 관련 연구가 진행되고 있다.Currently, polyurethane single foam with excellent thermal insulation is widely used for automobile seats, but various alternatives and supplements are being studied because problems such as limitation of function, lack of eco-friendliness, non-recyclability, condensation and embrittlement have been raised. . Recently, instead of a simple car seat composed of a single material or layer, new materials are laminated to greatly increase breathability and ride comfort, while effectively dispersing the body pressure of the occupant so that they do not feel fatigued even after long-time driving, and the car seat that increases safety in case of an accident Related research is in progress.

이에 본 발명은 고분자를 이용한 고탄성 섬유 시트를 개발하여 자동차 시트에 적용하는 것이 목표이며, 종래에 따른 자동차 시트가 2차원 구조의 직물을 사용하는 데 비해 본 발명은 3차원 구조의 직물 탄성체를 만들어 쿠션감을 주는 것이 목표이다. 이러한 3차원 구조의 직물 탄성체는 단일층이 아닌 복수 개의 층 중 중간층으로 형성되며, 원사와 원사 사이의 간격이 넓어 공기의 이동이 자유롭기 때문에 통기성이 향상될 수 있다. 즉, 본 발명에 따른 자동차 시트는 3차원 직물 탄성체를 포함하기 때문에 통기성, 쿠션감, 저수축, 난연성 및 고탄성의 기능을 가지며, 종래기술과 같이 폴리우레탄 발포폼을 사용하지 않고 환경에 무해한 소재로 이루어지기 때문에 작업자의 안전이 보장될 뿐 아니라 환경오염도 줄일 수 있다. 또한 부피가 큰 폴리우레탄 발포폼에 비해 슬림한 구조로 이루어는 3차원 직물 탄성체에 의해 자동차 시트 자체의 슬림성이 높아지며, 고탄성이 유지될 수 있다.Accordingly, the present invention aims to develop a high-elastic fiber sheet using a polymer and apply it to a car seat, and the present invention makes a three-dimensional fabric elastic body for cushioning, compared to the conventional car seat using a two-dimensional fabric. The goal is to give The elastic fabric of such a three-dimensional structure is formed as an intermediate layer among a plurality of layers rather than a single layer, and since the distance between the yarns is wide and air is free to move, ventilation can be improved. That is, the automobile seat according to the present invention has functions of breathability, cushioning, low shrinkage, flame retardancy and high elasticity because it contains a three-dimensional fabric elastic body, and it is made of a material harmless to the environment without using polyurethane foam as in the prior art. This not only ensures worker safety but also reduces environmental pollution. In addition, the slimness of the car seat itself is increased by the three-dimensional elastic body made of a slim structure compared to the bulky polyurethane foam, and high elasticity can be maintained.

이와 같은 본 발명에 따른 슬림성과 고탄성을 가지는 자동차 시트 제조방법은, 도 1 및 도 2에 도시된 바와 같이 몰드시트폼 준비단계(S100), 직물 탄성체 적층단계(S200), 라텍스폼 적층단계(S300) 및 시트커버 적층단계(S400)를 포함한다.As shown in Figs. 1 and 2, the method for manufacturing a car seat having a slimness and high elasticity according to the present invention is a mold sheet foam preparation step (S100), a fabric elastic body lamination step (S200), a latex foam lamination step (S300). ) and a seat cover lamination step (S400).

먼저, 몰드시트폼 준비단계(S100)는, 자동차 시트(10)의 구체적인 형상으로 이루어진 몰드시트폼(100)을 준비하는 단계를 의미한다. 예를 들어, 등받이 시트의 경우 등받이 형상으로 이루어진 몰드시트폼(100)을 준비한다. 여기서 몰드시트폼(100)은, 폴리올 100중량부에 대해 글리콜 3 내지 5중량부, 황변방지제 0.1 내지 1중량부, 촉매 0.1 내지 1중량부, 발포제 1 내지 10중량부를 포함한다. 폴리올의 경우 폴리에스테르 폴리올 또는 폴리에테르 폴리올을 적용 가능하나, 이 중 폴리에테르 폴리올을 사용하는 것이 좀 더 바람직하다.First, the mold seat form preparation step (S100) means a step of preparing the mold seat form 100 made of a specific shape of the vehicle seat 10 . For example, in the case of a backrest sheet, the mold seat form 100 made of a backrest shape is prepared. Here, the mold sheet foam 100 includes 3 to 5 parts by weight of glycol, 0.1 to 1 parts by weight of anti-yellowing agent, 0.1 to 1 parts by weight of catalyst, and 1 to 10 parts by weight of foaming agent based on 100 parts by weight of polyol. In the case of polyol, polyester polyol or polyether polyol can be applied, but it is more preferable to use polyether polyol among them.

직물 탄성체 적층단계(S200)는, 몰드시트폼(100)의 상면에 3차원 직물 탄성체(200)를 적층하는 단계를 의미한다. 이러한 직물 탄성체 적층단계(S200)는, 직물 탄성체 직조단계, 정련단계 및 분사단계를 통해 얻어진 직물 탄성체(200)를 몰드시트폼(100)의 상면에 적층한다.Laminating step (S200) of the elastic fabric means a step of laminating the three-dimensional fabric elastic body 200 on the upper surface of the molded sheet form (100). In this laminating step (S200) of the elastic fabric, the elastic fabric 200 obtained through the weaving step, refining step and spraying step is laminated on the upper surface of the mold sheet form 100 .

직물 탄성체 직조단계는 TPEE(ThermoPlastic Polyester Elastomer) 탄성사를 이용하여 더블라셀 방식으로 3차원 직물 탄성체(200)를 직조하는 단계를 의미한다. TPEE 탄성사는 폴리에스터(polyester)의 내구성과 폴리우레탄(polyurethane)의 신축성 및 유연성을 함께 보유하고 있는 탄성사로, 본 발명의 3차원 직물 탄성체(200)는 이러한 TPEE 탄성사를 이용하여 직조된다. 이때 TPEE 탄성사를 이용하여 3차원 직물 탄성체(200)를 직조시 TPEE 탄성사를 한 가닥이 아닌 복수 가닥으로 꼬은 후 이를 직조하여 고탄성력을 지니는 3차원 직물 탄성체(200)를 형성한다.The step of weaving the elastic fabric means a step of weaving the three-dimensional elastic body 200 in a double cell method using a ThermoPlastic Polyester Elastomer (TPEE) elastic yarn. The TPEE elastic yarn is an elastic yarn having the durability of polyester and the elasticity and flexibility of polyurethane together, and the three-dimensional elastic body 200 of the present invention is woven using the TPEE elastic yarn. At this time, when weaving the three-dimensional fabric elastic body 200 using the TPEE elastic yarn, the three-dimensional fabric elastic body 200 having high elasticity is formed by twisting the TPEE elastic yarn into a plurality of strands instead of one, and then weaving the TPEE elastic yarn.

3차원 직물 탄성체(200)의 직조 방식은 더블라셀 방식으로 직조하는 것이 바람직하다. 더블라셀(double raschel) 방식은 도 3에 도시된 바와 같이 상부직물(210) 및 하부직물(220)이 일정한 간격을 두고 상부 및 하부에 배치되도록 배열되고, 상부직물(210)과 하부직물(220)이 일체로 연결될 수 있도록 중간직물(230)이 직조되는 구조로 이루어진다. 즉, 상부직물(210)과 하부직물(220)이 수평으로 배치된 상태에서 중간직물(230)이 상부직물(210)과 하부직물(220)을 수직으로 연결하는 구조로 직조되는 것이 더블라셀 방식에 해당한다. The weaving method of the three-dimensional fabric elastic body 200 is preferably woven in a double cell method. In the double raschel method, as shown in FIG. 3 , the upper fabric 210 and the lower fabric 220 are arranged to be disposed on the upper and lower portions at regular intervals, and the upper fabric 210 and the lower fabric 220 ) has a structure in which the intermediate fabric 230 is woven so that it can be integrally connected. In other words, in a state in which the upper fabric 210 and the lower fabric 220 are horizontally arranged, the intermediate fabric 230 is woven in a structure that vertically connects the upper fabric 210 and the lower fabric 220 to the double cell method. corresponds to

상세하게는, 상부직물(210) 및 하부직물(220)에 연결되는 중간직물(230)이 하나는 수직으로 직조되고 다른 하나는 경사각을 갖도록 직조되어 수직탄성사(231)와 경사탄성사(232)가 서로 교대로 배치된다. 이러한 구조로 이루어질 경우 모든 탄성사가 수직으로 직조되거나 또는 모든 탄성사가 경사로 직조되는 경우에 비해 탄성과 인장강도가 우수해진다. 또한, 상부직물(210) 및 하부직물(220)은 직조 밀도가 중간직물(230)에 비하여 높게 이루어지기 때문에 더욱 고탄성의 3차원 직물 탄성체(200)가 직조된다. In detail, one intermediate fabric 230 connected to the upper fabric 210 and the lower fabric 220 is woven vertically and the other is woven to have an inclination angle, so that the vertical elastic yarn 231 and the warp elastic yarn 232 are placed alternately with each other. In the case of such a structure, elasticity and tensile strength are superior to those in which all elastic yarns are woven vertically or all elastic yarns are woven at an angle. In addition, since the upper fabric 210 and the lower fabric 220 have a higher weaving density than the intermediate fabric 230 , the three-dimensional fabric elastic body 200 of higher elasticity is woven.

이와 같이 3차원 직물 탄성체(200)는 상부직물(210), 하부직물(220) 및 중간직물(230)로 형성되며, 중간직물(230)의 밀도가 상부직물(210) 및 하부직물(220)보다 낮기 때문에 공기의 통과가 용이하다. 이로 인해, 사용자가 자동차 시트(10)를 지속적으로 사용하더라도 꺼짐이 발생하지 않고 제 형상이 탄성적으로 복구가능하도록 3차원으로 이루어진 3차원 직물 탄성체(200)를 형성할 수 있게 된다.In this way, the three-dimensional fabric elastic body 200 is formed of an upper fabric 210, a lower fabric 220 and an intermediate fabric 230, and the density of the intermediate fabric 230 is the upper fabric 210 and the lower fabric 220. Because it is lower, it is easier for air to pass through. Due to this, it is possible to form the three-dimensional fabric elastic body 200 made of three dimensions so that even if the user continues to use the vehicle seat 10, it does not turn off and its shape is elastically recoverable.

정련단계는, 3차원 직물 탄성체(200)를 80 내지 100℃에서 정련하는 단계를 의미한다. TPEE 탄성사의 경우 3차원 직물 탄성체(200)를 직조하는 과정에서 직조가 원활하게 이루어질 수 있도록 표면에 오일이 도포된 상태인데, 정련단계는 TPEE 탄성사에 의해 존재하는 3차원 직물 탄성체(200) 표면의 오일을 제거하는 단계에 해당한다. 이때 정련 온도가 80℃ 미만일 경우 3차원 직물 탄성체(200) 표면의 오일이 제대로 제거되지 않으며, 100℃를 초과할 경우 오일이 과하게 가열되어 3차원 직물 탄성체(200)의 변형이 발생할 수 있다.The refining step means a step of refining the three-dimensional fabric elastic body 200 at 80 to 100 °C. In the case of TPEE elastic yarn, oil is applied to the surface so that weaving can be performed smoothly in the process of weaving the three-dimensional fabric elastic body 200, and the refining step is performed by using the TPEE elastic yarn. It corresponds to the step of removing the oil. At this time, if the refining temperature is less than 80 ℃, the oil on the surface of the three-dimensional fabric elastic body 200 is not properly removed, and if it exceeds 100 ℃, the oil is excessively heated, and deformation of the three-dimensional fabric elastic body 200 may occur.

표 2는 기존에 판매되고 있는 자동차 시트를 70kg인 사용자가 5분, 10분, 15분 동안 앉은 후 자동차 시트의 상태를 테스트한 결과이며, 표 3은 본 발명의 3차원 직물 탄성체(200)를 포함하는 자동차 시트(10)를 70kg인 사용자가 5분, 10분, 15분 동안 앉은 후 자동차 시트(10)의 상태를 테스트한 결과이다. Table 2 shows the results of testing the state of the car seat after a user weighing 70 kg sits for 5 minutes, 10 minutes, and 15 minutes on a previously sold car seat, and Table 3 shows the three-dimensional fabric elastic body 200 of the present invention. It is a result of testing the state of the car seat 10 after a user weighing 70 kg including the car seat 10 sits for 5 minutes, 10 minutes, and 15 minutes.

기존에 판매되는 자동차 시트의 경우 평균압력(average pressure)이 0.0625kgf/㎠을 나타내는 데 비해, 본 발명에 따른 자동차 시트(10)의 경우 평균압력이 0.576kgf/㎠를 나타내는 것으로 확인되어 기존의 자동차 시트에 비해 착좌감이 우수한 것을 확인할 수 있다. 또한, 2D 및 3D 이미지(image)를 통해서도 확인할 수 있듯이 기존의 자동차 시트는 압력이 중심부에 몰려있으나, 본 발명의 자동차 시트(10)는 압력이 골고루 퍼져있기 때문에 평균압력이 낮은 것을 알 수 있다.In the case of an automobile seat sold in the past, the average pressure was 0.0625 kgf/cm 2 , whereas, in the case of the car seat 10 according to the present invention, it was confirmed that the average pressure was 0.576 kgf/cm 2 . It can be seen that the seated feeling is superior to that of the seat. In addition, as can be seen from the 2D and 3D images, it can be seen that the pressure of the conventional car seat is concentrated in the center, but the car seat 10 of the present invention has a low average pressure because the pressure is evenly spread.

본 발명에 따른 자동차 시트(10)는 3차원 직물 탄성체(200)를 포함하기 때문에 통기성, 쿠션감, 저수축, 난연성 및 고탄성의 기능을 가지며, 종래기술과 같이 폴리우레탄 발포폼을 사용하지 않고 환경에 무해한 소재로 이루어지기 때문에 작업자의 안전이 보장될 뿐 아니라 환경오염도 줄일 수 있다. 또한 부피가 큰 폴리우레탄 발포폼에 비해 슬림한 구조로 이루어는 3차원 직물 탄성체(200)에 의해 자동차 시트(10) 자체의 슬림성이 높아지며, 고탄성이 유지될 수 있다.Since the car seat 10 according to the present invention includes the three-dimensional fabric elastic body 200, it has the functions of breathability, cushioning, low shrinkage, flame retardancy and high elasticity, and does not use polyurethane foam as in the prior art. Since it is made of materials that are harmless to the environment, not only the safety of workers is guaranteed, but also environmental pollution can be reduced. In addition, the slimness of the automobile seat 10 itself is increased by the three-dimensional fabric elastic body 200 having a slim structure compared to the bulky polyurethane foam, and high elasticity can be maintained.

본 발명은 상기한 실시예에 한정되지 아니하며, 적용범위가 다양함은 물론이고, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 다양한 변형 실시가 가능한 것은 물론이다.The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention as claimed in the claims.
