Abstract
Description
본 발명은 부직포 제조방법에 관한 것으로, 보다 더 상세하게는 특성이 서로 다른 두개의 펠트(FELT)를 니들펀칭(Needle Punching)으로 상호 결합하고, 상기에서 결합된 펠트를 고온 온수에 함침함으로써 저밀도층과 고밀도층을 동시에 형성하기 위한 2중 구조를 가지는 부직포 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a nonwoven fabric, and more particularly, two felts having different characteristics are bonded to each other by needle punching, and the low density layer by impregnating the combined felt in hot water. And a nonwoven fabric manufacturing method having a double structure for simultaneously forming a high density layer.
일반적으로 부직포는 천연 또는 화학, 유리등의 각종 섬유소재를 상호간에 일정한 방향성이 없이 엉키게 하여 시트(sheet)형태의 웹(web)을 형성한 다음 이를 화학적 또는, 물리적인 방법으로 결합, 안정화시켜서 종이나 천과 같이 제조하여 산업현장이나 생활주변에서 사용목적에 따라 광범위하게 사용하고 있다.In general, nonwoven fabrics entangle various fiber materials such as natural, chemical, glass, etc. without a certain orientation to each other to form a sheet-shaped web, and then combine and stabilize them by chemical or physical methods. Manufactured like paper or cloth, it is widely used depending on the purpose of use in industrial sites and living areas.
최근, 인조 피혁용으로 사용되는 부직포는 각종 가방, 볼, 신발 등의 소재로 널리 사용되고 있으며, 특히 신발용으로 사용되는 부직포는 단일구조의 부직포로이루어지는 저밀도층에 쿠션이 있는 원단으로 이루어지는 고밀도층을 결합한 2중 구조의 원단을 널리 사용하고 있다.Recently, the nonwoven fabric used for artificial leather is widely used as a material for various bags, balls, shoes, etc. In particular, the nonwoven fabric used for shoes has a high density layer made of a fabric having a cushion in a low density layer formed of a single structure nonwoven fabric. Combined double fabric is widely used.
그러나, 상기 신발용으로 사용되는 2중 구조의 부직포는 상기 저밀도과 상기 고밀도층의 결합력이 약하여 별도의 결합공정을 거치므로 생산 공정이 복잡하고, 장시간 소요되며, 불필요한 생산 공정으로 인해 원자재의 낭비로 인한 생산 단가가 상승한다는 문제점이 있다.However, since the nonwoven fabric of the double structure used for the shoe has a low bonding strength between the low density and the high density layer and undergoes a separate bonding process, the production process is complicated, and takes a long time, due to waste of raw materials due to unnecessary production process. There is a problem that the production cost rises.
본 발명은 전술한 바와 같은 문제점을 감안하여 안출한 것으로, 그 목적은 특성이 서로 다른 두개의 펠트를 니들펀칭으로 상호 결합하고, 상기에서 결합된 펠트를 고온 온수에 함침하여 저밀도층과 고밀도층을 동시에 형성함으로써 고탄력, 경량의 2중 구조의 부직포를 생산하기 위한 제조공정을 단축하고, 제조원가를 감축하기 위한 것이다.The present invention has been made in view of the above-described problems, and an object thereof is to combine two felts having different characteristics with needle punching, and to impregnate the above-described felts with hot water to form a low density layer and a high density layer. By forming at the same time, the manufacturing process for producing a non-woven fabric having a high elasticity and light weight double structure is shortened, and the manufacturing cost is reduced.

도 1은 본 발명의 일 실시에에 따른 2중 구조를 가지는 부직포 제조방법을 도시한 순서도이다.1 is a flow chart illustrating a nonwoven fabric manufacturing method having a double structure according to an embodiment of the present invention.
도 1을 참조하면, 본 발명의 2중 구조를 가지는 부직포 제조공정은 1차, 2차펠트가공(T1, T2) →결합(U) →함침(P) →건조(D) 공정을 거치게 되는데 각 공정별 자세한 설명은 다음과 같다.Referring to Figure 1, the nonwoven fabric manufacturing process having a double structure of the present invention is subjected to the first, secondary felt processing (T1, T2) → bonding (U) → impregnation (P) → drying (D) Detailed description of each process is as follows.
1차, 2차 펠트가공(T1, T2)Primary and Secondary Felt Processing (T1, T2)
1차 펠트(T1)와 2차 펠트(T2)를 각각 분리하여 동시에 형성하게 되는데, 상기 1차 펠트(T1)는 폴리에스테르, 나이론 등의 일반섬유를 균일하게 혼합하는 제 1혼합공정(M1)과, 상기 혼합공정에서 혼합된 섬유를 일정한 중량의 웨브(Web)로 형성하는 제 1소면공정(Carding, C1)과, 상기에서는 형성된 웨브를 적층하여 일정한 두께와 폭을 가지는 편평포 상태로 형성하는 제 1성형공정(Forming, F1)과, 상기 성형 공정에서 형성된 평편포 상태의 웨브를 다수개의 바늘로 상하로 펀칭하는 제 1니들펀칭 공정(N1)을 거쳐 형성된다.The primary felt (T1) and the secondary felt (T2) are separated and formed at the same time. The primary felt (T1) is a first mixing process (M1) for uniformly mixing common fibers such as polyester and nylon. And a first carding process (Carding, C1) for forming the fibers mixed in the mixing process into a web of constant weight, and the web formed in the above, to form a flat fabric having a predetermined thickness and width. It is formed through a first forming process (F1) and a first needle punching process (N1) for punching up and down the web of the flat knitted state formed in the forming process with a plurality of needles.
상기 2차펠트(T2)는 상기 1차펠트(T1)와 동일한 공정을 거처 형성되는데, 폴리에스테르, 나일론 등의 일반섬유에 30% ~ 40%의 열수축 섬유를 첨가하여 혼합하는 제 2혼합공정(M2)과, 상기 1차펠트와 동일한 제 2소면(C2), 제 2성형(F2), 제 2니들펀칭(N2)공정을 거처 형성된다.The secondary felt (T2) is formed through the same process as the primary felt (T1), the second mixing step of mixing by adding 30% to 40% heat-shrinkable fiber to ordinary fibers such as polyester, nylon ( M2) and the same second facet (C2), second molding (F2), and second needle punching (N2) process as the first felt.
상기 2차펠트 형성시 첨가되는 열수축 섬유로는 80℃ ~ 90℃에서 열수축되는 기능성 폴리에스테르를 사용하는 것이 바람직하다.As the heat-shrinkable fiber added when the secondary felt is formed, it is preferable to use a functional polyester that is heat-shrunk at 80 ° C to 90 ° C.
결합공정(U)Joining Process (U)
상기 가공공정에서 형성되는 1차펠트와 2차펠트를 다수개의 바늘로 상하 펀칭하여 상호 견고하게 결속 되도록 니들펀칭하여 2중 펠트를 형성한다.The primary felt and the secondary felt formed in the processing process by punching up and down with a plurality of needles to form needles to bind to each other firmly to form a double felt.
함침공정(P)Impregnation Process (P)
상기 결합공정에서 1차펠트와 2차펠트가 결합되면, 상기 결합된 펠트를 80℃ ~ 90℃의 고온 온수에 함침시킨다.When the primary felt and the secondary felt is combined in the bonding process, the combined felt is impregnated in hot water of 80 ℃ ~ 90 ℃.
이때, 일반섬유가 함유되어 있는 1차펠트는 정상상태로 존재하고, 상기 1차펠트와 결합되어 있는 2차펠트는 고온의 온수에 의해 수축하게 된다.At this time, the primary felt containing the normal fiber is present in the normal state, the secondary felt combined with the primary felt is contracted by hot water of high temperature.
따라서, 상기 1차펠트는 저밀도층을 형성하고, 상기 2차펠트는 열수축에 의해 고밀도층을 형성하게 된다.Therefore, the primary felt forms a low density layer, and the secondary felt forms a high density layer by thermal contraction.
건조공정(D)Drying process (D)
상기 함침공정을 거쳐 저밀도층과 고밀도층으로 형성되어 있는 2중 펠트를 탈수하여 140℃ ~ 160℃의 건열로 건조한다.After the impregnation process, the double felt formed of the low density layer and the high density layer is dehydrated and dried in a dry heat of 140 ° C to 160 ° C.
이상에서 설명한 바와 같이 본 발명은 폴리에스테, 나일론 등의 일반섬유가 함유되어 있는 1차펠트와, 상기 일반섬유에 열수축섬유가 혼합된 2차펠트를 각각분리하여 형성하고, 상기 1차펠트와 2차펠트를 니들펀칭하여 상호 결합한 다음, 상기에서 결합된 펠트를 고온 온수에 함침함으로써 2중 구조의 저밀도층과 고밀도층을 동시에 형성한다.As described above, the present invention is formed by separating a primary felt containing general fibers such as polyester and nylon, and a secondary felt mixed with heat shrink fibers in the general fiber, and the primary felt and the second felt. After the chapels are needle-punched to each other, the felts are impregnated with hot water to form a low density layer and a high density layer having a double structure.
따라서, 서로 특성이 다른 2개의 펠트를 고온의 온수에 함침하여 2중 구조의 부직포를 제조함으로써 이를 활용할 수 있는 각종원단(신발, 볼, 가방 등)에 사용되는 부직포의 생산공정을 단축하고, 상기 생산공정의 단축으로 원자재비를 절감할 수 있으므로 낮은 생산원가로 2중구조의 부직포를 생산할 수 있다.Therefore, the production process of the nonwoven fabric used for various fabrics (shoes, balls, bags, etc.) that can utilize the same by manufacturing a non-woven fabric having a double structure by impregnating two felts with different characteristics into hot water at high temperature Since the raw material cost can be reduced by shortening the production process, it is possible to produce nonwoven fabric of double structure with low production cost.
