본 발명은 열가소성용융층이 코팅된 연사 및 상기 열가소성용융층이 코팅된 연사에 의한 방수처리방법에 관한 것으로, 특히 구체적으로 설명하면, 천연섬유나 나일론이나 폴리에스테르로 제조된 연사를 열가소성수지로 코팅시키고 그 위에 실리콘과 같은 유연제로 다시 코팅시켜 마찰력을 최소로 함과 동시에 상기 연사를 사용하여 봉재를 수행한 후에 상기 연사를 200℃에 가까운 온도로 다림질하여 상기 연사에 형성된 열가소성수지가 녹아내리면서 연사로 재봉된 직물의 구멍을 메워 간단하게 방수처리할 수 있는 열가소성용융층이 코팅된 연사 및 상기 열가소성용융층이 코팅된 연사에 의한 방수처리방법에 관한 것이다. The present invention relates to a method of waterproofing by the thermoplastic yarns coated with a molten thermoplastic coating and the twisted yarns coated with the thermoplastic molten layer. Specifically, the present invention relates to coating a twisted yarn made of natural fibers or nylon or polyester with a thermoplastic resin. And coating again with a softening agent such as silicone to minimize friction and at the same time perform the sewing using the twisted yarn, and then iron the twisted yarn to a temperature close to 200 ° C to melt the thermoplastic resin formed in the twisted yarn. The present invention relates to a yarn coated with a thermoplastic molten layer which can be easily waterproofed by filling a hole of a fabric sewn with a yarn, and a method of waterproofing by a twisted yarn coated with the thermoplastic molten layer.

일반적으로, 등산복이나 공장의 가림막에는 방수처리가 필수적으로 인식되고 있다. 이러한 등산복이나 공장의 가림막의 방수처리는 방수가 되는 천을 이용하여 방수처리를 하게 되므로 대부분의 방수처리는 만족할만하다고 사료되나 그러나 이음매부분의 방수처리는 불충분하여 이부분을 통하여 물기가 습기가 침투되고 있는 실정으로 이음매부분의 방수처리를 위하여는 이음매부분에만 사용되는 별도의 방수접착테이프가 필수적으로 사용되고 있다는 문제점이 있었다.In general, waterproofing is recognized as essential for mountain climbing clothes and factory screens. Such waterproofing of mountaineering suits or factory screens is considered to be satisfactory because the waterproofing is performed using a waterproofing cloth. However, the waterproofing of the seam is insufficient. As a matter of fact, for the waterproof treatment of the joint part, there was a problem that a separate waterproof adhesive tape used only for the joint part was used.

즉, 이음매부분의 방수처리에는 별도의 방수접착테이프가 필요하게 되고 이러한 방수접착테이프는 이음매의 형상에 따라서 여러 형상으로 절단되어야 하며 적정한 온도에서 녹아서 방수처리가 되어야 하므로 방수처리를 위한 다수의 추가 공정이 필요하게 되어 제조기간이 연장되어 제조원가가 높아지는 것은 물론이고 추가적인 제조인력이 필요하게 되므로 노동성이 저하되고 제조원가가 높아지게 되는 근본적으로 해결되어야 하는 문제점이 있었다.That is, a separate waterproof adhesive tape is required for the waterproofing of the joint part, and the waterproof adhesive tape must be cut into various shapes according to the shape of the joint, and it must be melted at an appropriate temperature to be waterproofed. This necessitates a prolonged manufacturing period, resulting in higher manufacturing costs, as well as additional manufacturing manpower, which has a problem that is fundamentally solved, resulting in lower labor and higher manufacturing costs.

이러한 근본적인 문제점은 바늘을 통하여 재봉하게 되면 재봉된 부분에서 실과 실이 통과된 재봉구멍의 사이에 미세한 공간이 발생되고 이러한 공간을 통하여 물이 흡수되어 침입하거나 하게 되는 것으로, 재봉을 통하여 방수물품이 제조되는 등산복, 등산용 텐트, 공장의 가림막, 가방 과 같은 방수가 필요한 물품에서는 이음매의 방수에는 반드시 방수접착테이프의 사용이 필요하게 되는 것이다. This fundamental problem is that when sewing through a needle, a fine space is generated between the thread and the sewing hole passed through the thread in the sewn part, and water is absorbed and penetrated through the space, thereby making the waterproof article through sewing. For waterproofing items such as hiking clothes, hiking tents, factory screens, bags, etc., it is necessary to use a waterproof adhesive tape for waterproofing seams.

폴리에틸렌수지(Polyethylene resin)는 에틸렌 CH=CH를 중합해 얻어지는 고분자의 총칭으로, PE로 약칭되며 유백색·반투명의 열가소성수지(熱可塑性俊脂)이나, 그 특성에 의해 부드러운 저밀도 폴리에틸렌(LDPE)과 단단하고 강인한 폴리에틸렌(HDPE)으로 분류되고, 앞의 것은 고압법 폴리에틸렌, 뒤의 것은 저·중압법 폴리에틸렌으로 불린다. 최근 저압법으로도 저밀도 폴리에틸렌이 만들어지게 되었고, 이것은 직쇄상(直鎖狀) 저밀도 폴리에틸렌(LLDPE)으로 불린다. 고압법으로는 분기(分岐)가 많은 선(線)형 고분자로 짧은 가지가 붙은 폴리에틸렌이 만들어지는 데 대해, 저압법으로는 직쇄형 폴리에틸렌이 얻어져 결정화(結晶化)되기 어렵기 때문이다. 연화점은 낮지만 물보다 가볍고 내충격성이 뛰어나 강하며, 내수성(耐水性) ·내한성(耐寒性)·전기특성(電氣特性)도 뛰어나다. 특히 나프타의 열분해로 많은 양을 쉽게 얻을 수 있는 에틸렌이 원료로 제조되어, 섬유·필름 및 어떤 성형품으로나 성형되기 때문에 석유화학 발전에 따라 급속하게 용도가 늘어났다.Polyethylene resin is a general term for a polymer obtained by polymerizing ethylene CH = CH. It is abbreviated as PE and is milky white and translucent thermoplastic resin, but soft low density polyethylene (LDPE) and hard It is classified as tough polyethylene (HDPE), and the former is called high pressure polyethylene and the latter is called low and medium pressure polyethylene. In recent years, low-density polyethylene has also been produced by the low pressure method, which is called linear low-density polyethylene (LLDPE). This is because a polyethylene having a short branch is made of a linear polymer having many branches by the high pressure method, but a linear polyethylene is obtained by the low pressure method and it is difficult to crystallize. Although it has a low softening point, it is lighter than water and excellent in impact resistance, and has excellent water resistance, cold resistance, and electrical characteristics. In particular, ethylene, which can be easily obtained in large quantities by pyrolysis of naphtha, is manufactured from raw materials and formed into fibers, films, and any molded products, and thus its use has rapidly increased in accordance with petrochemical development.

폴리프로필렌수지(Polyproplene resin)는 물리적 성질이 폴리에틸렌보다 뛰어나지만 산소 존재하에서 빛이나 열에 산화열화(酸化劣化)하는 결점이 있으며 안정제(安定劑)를 필요로 한다. 한편 비중이 0.9정도로 가장 가벼운 플라스틱이며 강성·내충격성·전기적 특성이 뛰어나고 값이 싸 이용범위가 넓으며 이축연신(二軸延伸) 폴리프로필름으로서 필름 분야, 플랫얀(flat yarn) 카펫 등의 섬유분야, 컨테이너·약전부품(弱電部品) 등의 사출성형(射出成形) 분야에 주로 이용된다. 최근에는 고무·필터와의 복합물이 자동차 범퍼, 그 밖의 자동차부품, 패널 등 대형 공업부품으로 이용이 확대되고 있으며, 프로필렌처럼 비닐기 CH=CH-를 갖는 모노머는 중합하면 입체화학적으로 곁사슬 메틸기가 분자사슬을 따라 규칙적으로 배열하는 것과 그렇지 않은 것으로 나뉜다. 종래의 라디칼성중합으로는 랜덤으로 규칙적 배열을 한 비결정성 어택틱폴리프로필렌밖에 만들지 못하지만, 치글러-나타촉매를 쓰면 곁사슬 메틸기가 언제나 한 방향으로 배열된 결정성 아이소택틱프로필렌을 만들 수 있다. 현재는 폴리프로필렌을 무용제(無溶劑)나 기상중합(氣相重合)으로 만들고 있으며 이러한 폴리프로필렌수지가 사용될 수 있다. Polypropylene resin has better physical properties than polyethylene but has the disadvantage of being oxidatively deteriorated in light or heat in the presence of oxygen and requires a stabilizer. On the other hand, it is the lightest plastic with a specific gravity of about 0.9, and has excellent rigidity, impact resistance, and electrical properties, and is cheap, so that it has a wide range of use. It is mainly used in the field of injection molding of the field, container, and pharmacy parts. In recent years, composites with rubber and filters have been widely used in large industrial parts such as automobile bumpers, other automobile parts, and panels, and monomers having a vinyl group CH = CH- like propylene are stereochemically side chain methyl groups. It is divided into regular arrangement along the chain and non-arrangement. Conventional radical polymerization only produces randomly arranged amorphous atactic polypropylene, but using a Ziegler-Natta catalyst can produce crystalline isotactic propylene in which side chain methyl groups are always arranged in one direction. Currently, polypropylene is made of solvent-free or vapor phase polymerization, and such polypropylene resin can be used.

포리에스테르수지(Polystyrene resin)는 분자 내에 에스테르결합-CO-O-을 갖는 고분자화합물의 총칭으로서, 알키드수지·폴리에틸렌테레프탈레이트(PET)로 대표되는 열가소성 폴리에스테르가 있다. 일반적으로는 2가 이상의 알코올과 2가 이상의 카르복시산의 축합중합에 의해 만들어진 것이 사용될 수 있다. Polystyrene resin is a general term for the high molecular compound which has ester bond -CO-O- in a molecule | numerator, and there exists thermoplastic polyester represented by alkyd resin and polyethylene terephthalate (PET). Generally, those made by condensation polymerization of dihydric or higher alcohols and divalent or higher carboxylic acids can be used.

Ultraviolet rays transmit better than ordinary glass. It does not discolor when exposed to the outdoors, has good chemical resistance, good electrical insulation and water resistance, and polymers and hybrid polymers of acrylic acid, its methyl esters and ethyl esters are considered important as fibers and paper processing, especially new paints and adhesives. .

염화비닐수지는 단독중합체라도 분자량에 따라 성질이 달라진다. 중합은 과산화물과 아조산계(azo 酸系) 촉매를 써서 이루어지는데, 빛 ·α선의 조사(照射)로도 중합된다. 중합방식은 에멀션화 중합법과 서스펜션중합법의 두 가지가 있으며, 물 속에 염화비닐을 분산시켜서 중합열을 분산시킨다. 반응조건에 따라 성질이 다른 각종 중합도의 것이 생긴다. 중합체는 결정성이 현저하게 낮아서 빛 ·열로 인해 분해하여 황색 또는 갈색으로 착색된다. 실온에서 모든 산 ·알칼리 ·산화제에 안정하고, 아세톤 ·알코올 ·벤젠에도 녹지 않기 때문에 가공시의 접착이 어렵다. 테트라히드로푸란 ·시클로헥사논 등에는 녹는다. 폴리염화비닐은 단독으로 비교적 단단하고 잘 부서지나, 프탈산디옥틸과 같은 가소제를 첨가하면 탄성을 갖는다. 염화비닐은 스티렌 ·아세트산비닐 ·아크릴산메틸 ·염화비닐리덴 등과 혼성 중합하며, 혼합중성체는 단독중합체보다 가공온도가 낮아 유연성이 있다.Although vinyl chloride resins are homopolymers, their properties vary depending on the molecular weight. The polymerization is carried out using a peroxide and an azo acid catalyst, but also polymerization by irradiation of light and alpha rays. There are two types of polymerization methods: emulsification polymerization and suspension polymerization. The heat of polymerization is dispersed by dispersing vinyl chloride in water. The thing of various degree of polymerization with a different characteristic is produced according to reaction conditions. The polymer has a remarkably low crystallinity, which decomposes due to light and heat and turns yellow or brown. It is stable to all acids, alkalis, and oxidizing agents at room temperature, and is insoluble in acetone, alcohol, and benzene. It is soluble in tetrahydrofuran cyclohexanone and the like. Polyvinyl chloride alone is relatively hard and brittle, but has an elasticity when a plasticizer such as dioctyl phthalate is added. Vinyl chloride is hybridized with styrene, vinyl acetate, methyl acrylate, vinylidene chloride, and the like, and mixed neutrals have a lower processing temperature than homopolymers and thus have flexibility.

The twisted yarn chamber 1 in which the thermoplastic resin molten layer 2 is dried proceeds to step S20.

단계 S20에서는 열가소성 수지로 코팅된 연사실(1)을 2차로 실리콘 수지의 액상 조성물이 담겨진 제2침지조(P2)에 침지시켜 코팅한다. 실리콘 수지는 주지하다시피, 규소와 산소를 골격으로 하고, 알킬기나 아릴기가 결합한 그물 구조를 가진 고분자 물질로서 -60℃~300℃ 사이에서는 내열성, 내한성, 내습성이 강하므로 항공기의 윤활유, 전기 절연체, 방수제 따위로 사용되며, 본 실시예에서는 방수천을 용이하게 통과하는 윤활유의 역할로서 도포되는 물질이다. 반드시, 실리콘수지가 아니고 이에 대체되는 물질은 모두 등가물로서 본 발명의 권리에 포함된다고 할 것이다. 상기 유연재로서 사용되는 물질은 실리콘 수지로 한정되지 않고 이 기술의 당업자에게 알려진 다른 주지의 물질이 사용될 수 있음은 물론이라고 할 것이다.In step S20, the twisted yarn chamber 1 coated with a thermoplastic resin is immersed and coated in a second immersion tank P2 in which the liquid composition of the silicone resin is secondarily coated. As is well known, silicone resin is a macromolecular substance having a structure of silicon and oxygen, and having an alkyl group or an aryl group, and has a high heat resistance, cold resistance, and moisture resistance between -60 ° C and 300 ° C. It is used as a waterproofing agent, and in this embodiment, the material is applied as a role of lubricating oil easily passing through the waterproof cloth. All materials not necessarily silicone resins and substitutes for them will be included in the rights of the present invention as equivalents. The material used as the softening material is not limited to the silicone resin, of course, other well-known materials known to those skilled in the art may be used.

이어서, 단계 S30에서는, 상기 단계 S10, S20에서 코팅된 열가소성용융층이 코팅된 연사(A)를 이용하여 등산복과 같이 방수가 필요한 이음매부분의 방수천(B1,B2)을 봉재처리하고, 상기 방수천(B1,B2)에 생긴 재봉홈(B3)이 형성되고, 이와 같이 봉재된 부분의 열가소성수지용융층이 코팅된 연사(A)를 200℃의 고온으로 열처리하여 상기 열가소성수지용융층이 코팅된 연사(A)의 열가소성수지용융층(2)이 용융되면서 재봉홈(B3)내로 유입되어 방수가 필요한 부분을 충진시켜 방수처리가 완성된다. 재봉부분의 연사실을 연화시켜 통과한 직물의 구멍을 메우는 단계가 수행된다. 상기 다림질을 포함한 열처리온도가 200℃의 고온으로 설정된 이유는 섬유별 다림질 온도가 상이하게 되어, 천연섬유는 면 또는 마 - 180~200도, 모 - 150~160도, 레이온 - 140~150도, 견 - 130~140도이고, 합성섬유는,나일론,폴리에스테르 - 120~130도, 폴리우레탄 - 130도 이하 아세테이트,트리아세테이트,아크릴 - 120도 이하이므로 200℃이상으로 설정하였다.Subsequently, in step S30, by using the twisted yarn (A) coated with the thermoplastic molten layer coated in the steps S10, S20 to seal the waterproof cloth (B1, B2) of the joint portion required waterproofing, such as mountaineering clothing, the waterproof The sewing grooves B3 formed on the fabrics B1 and B2 are formed, and the twisted yarn A coated with the thermoplastic resin melt layer of the sealed portion is heat-treated at a high temperature of 200 ° C. to which the thermoplastic resin melt layer is coated. As the thermoplastic resin melted layer 2 of the twisted yarn A is melted, the thermoplastic resin melted layer 2 is introduced into the sewing groove B3 to fill a portion requiring waterproofing, thereby completing the waterproofing treatment. Softening the yarn thread of the sewing portion is performed to fill the hole of the fabric passed. The reason that the heat treatment temperature including the ironing is set to a high temperature of 200 ℃ is different ironing temperature for each fiber, natural fibers are cotton or hemp-180 to 200 degrees, wool-150 to 160 degrees, rayon-140 to 150 degrees, Silk-130 ~ 140 degrees, synthetic fibers, nylon, polyester-120 ~ 130 degrees, polyurethane-130 degrees or less acetate, triacetate, acrylic-120 degrees or less, so it was set to 200 ℃ or more.

이와 같은 과정은 도 4a에는 연사(A)가 방수천(B1,B2)에 봉제되어 상기 방수천(B1,B2)에 미세한 재봉홈(B3)이 형성된 형태이고, 이러한 재봉홈(B3)을 통하여 물이 스며들게 되나, 도 4b에 도시된 바와 같이, 연사(A)를 열처리하게 되면 열가소성수지용융층(2)이 용융되면서 용융된 열가소성수지가 재봉홈(B3)을 메우게 되면서 물이 스며드는 공간을 폐쇄시키게 되므로 물은 방수천(B1,B2)의 내부로 스며들지 않고 외부로 흐르게 되는 것이다.In this process, the yarn A is sewn in the waterproof cloths B1 and B2 in FIG. 4A to form a fine sewing groove B3 in the waterproof cloths B1 and B2, and through the sewing groove B3. As water is permeated, but as shown in Figure 4b, when the thermal yarn (A) is heat-treated, the thermoplastic resin melted layer (2) is melted while the molten thermoplastic resin fills the sewing groove (B3) space for water seeps Since it is closed, the water flows to the outside without penetrating into the interior of the waterproof cloth (B1, B2).
