Description

통기성 방수원단의 제조방법{the manufacturing process of micro porous waterproof}The manufacturing process of micro porous waterproof

본 발명은 땀 등의 습기 배출은 원활하게 이루어지면서 방풍 및 방수가 이루어지는 통기성 방수원단의 제조방법에 관한 것으로, 특히 2레이어(Layer)와 3레이어(Layer)의 중간형태인 2.5레이어(Layer)의 층을 가진 방수원단의 제조방법을 제공하여 땀의 배출등 투습기능이 매우 원활하게 이루어지면서 방수, 방풍 등의 기능 또한 우수한 원단을 제조하기 위한 것이다.The present invention relates to a method for manufacturing a breathable waterproof fabric which is windproof and waterproof while the moisture is discharged smoothly, in particular, 2.5 layer (Layer) which is an intermediate form between two layers and three layers (Layer) Providing a method of manufacturing a waterproof fabric with a layer is to produce a fabric that is also excellent in waterproof, windproof, etc. while the moisture permeation function such as sweat discharge is made very smoothly.

주지된 바와 같이 방수원단은 투습성과 방수기능이 부여된 원단을 말하며, 통상 제직된 직물의 표면에 우레탄 등의 수지를 이용하여 표면코팅을 한 것을 말한다.As is well known, the waterproof fabric refers to a fabric provided with moisture permeability and waterproof function, and usually means surface coating using a resin such as urethane on the surface of a woven fabric.

상기한 투습성이란 방수원단을 이용하여 의복 등을 제조하여 착용하였을 때 쾌적성을 부여하는 매우 중요한 기능을 말하며, 통상 인체활동에 의해 발생되는 수증기는 평상시 350~600g/㎡/24hr이고, 운동시는 적어도 2500g/㎡/24hr 이상의 투습도가 필요하며, 스키나 등산 등과 같이 격렬한 운동을 하거나 우의나 텐트 등의 장비 또는 기상조건이 매우 좋지 않을 때 착용하는 특수복 등의 투습도는 최소4000g/㎡/24hr이다.The moisture permeability is a very important function of imparting comfort when wearing clothes and the like using waterproof fabrics. Normally, water vapor generated by human activities is usually 350 to 600 g / m 2/24 hr. At least 2500g / ㎡ / 24hr moisture permeability is required, and at least 4000g / ㎡ / 24hr moisture permeability, such as skiing or mountaineering, special sports wear such as rain or tent equipment or bad weather conditions.

또한, 기상조건에 따라 내리는 이슬비는 입자크기가 100㎛, 보슬비는 500㎛, 비는 2000㎛, 소나기는 3000㎛이며, 인체에서 발생되는 땀 등의 수증기는 0.0004㎛이다.In addition, the drizzle falls according to the weather conditions, the particle size is 100㎛, the drizzle ratio is 500㎛, the rain is 2000㎛, the shower is 3000㎛, water vapor such as sweat generated in the human body is 0.0004㎛.

따라서 투습과 방수가 동시에 이루어지는 기능성원단이라면, 외부로 부터 물이나 바람의 침투가 방지되면서 인체에서 발산되는 땀 등의 배출이 원활하게 이루어질 수 있을 정도의 투습도를 가져야만 하는 것이다.Therefore, if the functional fabric is a moisture permeable and waterproof at the same time, the water or wind from the outside to prevent the penetration of sweat emitted from the human body should have a degree of permeability enough to be made smoothly.

한편, 상기한 방수원단에 있어서, 레이어(Layer)란 원단에 형성한 도공물 층 또는 겹을 말하며 통상 2레이어(Layer)와 3레이어(Layer)가 있다.On the other hand, in the waterproof fabric, the layer (Layer) refers to the coating layer or layer formed on the fabric, there are usually two layers (Layer) and three layers (Layer).

2레이어(Layer)는 원단에 건식 또는 습식, 라미네이팅 방법으로 코팅한 제품을 말하며, 3레이어(Layer)는 상기 2레이어(Layer) 제품에 접착제를 사용하여 니트 또는 폴라 폴리스로 합포한 제품을 말한다.Layer 2 refers to a product coated with a dry, wet, or laminating method on the fabric, Layer 3 refers to a product that is laminated with a knit or polarpolis using an adhesive to the layer 2 product (Layer).

2레이어(Layer) 원단은 중량이 가볍고 감촉이 부드러우며 내구성이 양호한 반면에 의류 등으로 제조할 때 안감을 필히 사용해야하고 더불어 코팅면을 아웃셀(Outshell)로 사용할 수 없는 단점이 따른다.While the two-layer fabric is light in weight, soft in touch, and good in durability, it is necessary to use lining when manufacturing clothes, etc., and the coated surface cannot be used as an outshell.

3레이어(Layer) 원단은 안감 없이 사용이 가능하고 내구성이 좋은 반면에 중량이 무겁고 감촉이 딱딱하고 뻣뻣하며 코팅면을 아웃셀(Outshell)로 사용할 수 없는 결점과 함께 작업공정난이도가 높아 제조원가가 과다하게 드는 폐단이 따른다.Three-layer fabrics can be used without lining and have good durability, but they are heavy in weight, hard to feel and stiff, and the manufacturing process is high due to the difficulty of using the coated surface as an outshell and high work process difficulty. Followed by the closing.

따라서 투습방수가 원활하게 이루어지면서도 가볍고, 안감없이 사용가능하며, 부드럽고, 내구성이 양호함은 물론 코팅면이 미려하고 아웃셀(Outshell)로 사용가능한 원단의 개발이 매우 시급한 실정인 것이다.Therefore, while the waterproofing is made smoothly, light, can be used without lining, soft, good durability, as well as the beautiful surface and the development of a fabric that can be used as an outshell (Outshell) is very urgent situation.

본 발명은 전술한 종래의 제반문제점을 감안하여 안출된 것으로서, 특히, 2레이어(Layer)와 3레이어(Layer)원단의 결점을 해결한 2.5레이어(Layer)의 투습방수원단을 제조하는 방법을 제공하려는데 그 목적이 있는 것이다.The present invention has been made in view of the above-described conventional problems, and in particular, provides a method for manufacturing a 2.5-layer (permeable) waterproof waterproof fabric which solves the shortcomings of the two-layer and three-layer fabric. The purpose is to do that.

본 발명은 다음과 같은 공정으로 이루어진다.The present invention consists of the following steps.

제 1공정;염색공정1st process; dyeing process

먼저 제직된 원단을 염색기를 통하여 소정의 색상으로 염색한다.First, the woven fabric is dyed to a predetermined color through a dyeing machine.

우레탄수지와 D.M.F용제를 혼합하여서 된 코팅액을 코팅롤에 공급하여 원단 표면에 도포 한 뒤 응고조의 물속을 통과시켜 우레탄수지를 고착시킨다.Supply the coating solution by mixing urethane resin and D.M.F solvent to the coating roll and apply it to the surface of fabric and pass urethane resin through the water of coagulation bath.

제 5공정;셋팅(Setting)5th process; setting

위 공정을 통과한 원단에 열을 가하여 건조 셋팅시킨다.Dry the fabric by applying heat to the fabric that passed the above process.

제 6공정; 프린트(Print)Sixth step; Print

엠보싱롤러 등을 이용하여 코팅면에 다양한 요철문양을 형성한다.Embossing rollers are used to form various irregularities on the coated surface.

제 7공정; 셋팅(Setting)7th process; Setting

요철문양이 형성된 원단에 열을 가하여 셋팅함으로서 요철문양이 변형되거나 풀어지지 않게 고착시킨다.By applying heat to the fabric on which the uneven pattern is formed, the uneven pattern is fixed so as not to be deformed or released.

이와 같은 공정으로 이루어진 본 발명의 공정에 따르면, 원단을 소정의 색상으로 염색한 후 이를 텐타기를 통하여 펴서 말린 뒤, 바로 카렌더 롤을 통하여 가압함으로서 보다 평평하게 펴고, 이어서 원단 표면에 우레탄수지(10~40중량%)와 D.M.F용제(90~60중량%)를 혼합하여서 된 코팅액을 코팅롤러를 이용하여 도포한 뒤, 물이 담긴 응고조에 침지시킨 다음 텐타기를 통하여 셋팅시킴으로서 원단표면에 우레탄 코팅이 이루어지는 것이며, 이어서 상기 원단표면에 각종 문양으로 엠보싱한 뒤, 셋팅시키는 과정을 거쳐 엠보싱문양을 고정시키는 등의 일련의 공정을 통하여 투습 및 방수효과가 뛰어난 원단을 제조하게 된다.According to the process of the present invention made of such a process, the fabric is dyed to a predetermined color, then stretched through a tenter and dried, and then flattened evenly by pressing through a calender roll, and then urethane resin (10) on the fabric surface. ~ 40% by weight) and DMF solvent (90-60% by weight) are coated with a coating roller and then coated in a coagulation bath containing water, and then set by a tenter to set the urethane coating on the fabric surface. Then, the fabric surface is embossed with various patterns, and then through the process of setting the embossed pattern is fixed through a series of processes such as manufacturing a fabric having excellent moisture permeability and waterproof effect.

한편, 상기 제 4공정에서 우레탄수지와 D.M.F용제를 혼합하여 원단표면에 도포한 후 물속에 침지시키면, 상기 D.M.F용제의 특성이 물에 희석 치환되는 성질이 있기 때문에 우레탄수지에 0.2~10㎛크기의 미세한 구멍을 무수하게 형성하게 되는 것이며, 따라서 인체에서 발산되는 땀 등의 수증기(0.0004㎛)는 원활하게 배출되는 투습효과가 뛰어나면서 입자가 작은 이슬비(100㎛) 등을 비롯한 물기의 침투가 예방되어 방수효과가 뛰어나게 됨은 물론 방풍효과도 뛰어나게 된다.On the other hand, when the urethane resin and the DMF solvent is mixed in the fourth step and coated on the surface of the fabric and immersed in water, the DMF solvent has a property of dilution and substitution with water. The fine pores are formed innumerably. Therefore, water vapor (0.0004 μm) such as sweat emitted from the human body has excellent moisture permeation effect and is easily prevented from penetrating water, including small particles of dew (100 μm). The waterproof effect is excellent as well as the wind effect is excellent.

또한, 본 발명은 제 7공정의 프린트공정을 통하여 원단표면의 코팅면에 각종 문양을 엠보싱한후 이를 셋팅공정을 통하여 고정화시킴으로서, 감촉이 매우 부드럽고 아웃셀(Outshell)로 사용이 가능하며 2.5레이어를 가진 원단으로서의 기능이 이루어지게 된다.In addition, the present invention by embossing the various patterns on the coating surface of the fabric surface through the printing process of the seventh step and then immobilized them through the setting process, the texture is very soft and can be used as an outshell (2.5 layer) The function as a fabric having is achieved.

이상 설명한 바와 같이 본 발명의 방법을 통하여 제조된 원단은 종래 2레이어 원단과 같이 감촉이 매우 부드럽고 가벼우면서도 의류제조시 3레이어 원단에서와 같이 안감없이 사용가능하고, 또, 내구성이 뛰어남은 물론 표면에 각종 입체문양이 형성되어 있어 외관이 미려한 등의 특징이 따르게 되어 캐쥬얼 웨어, 우의, 낚시 또는 등산용 의류 등 다양하게 사용할 수 있는 등의 통기성을 가진 방수원단을 제공하는 방법으로서 매우 유용한 발명인 것이다.As described above, the fabric produced by the method of the present invention is very soft and light as in the conventional two-layer fabric, and can be used without lining as in the three-layer fabric during garment manufacturing, and also has excellent durability and surface. It is a very useful invention as a method of providing a waterproof fabric having a breathable, such as various wear, such as casual wear, raincoats, fishing or mountaineering clothing, which is characterized by a variety of three-dimensional patterns and beautiful appearance.
