Abstract

Fine composite yarns are composed of polyester and nylon with their single fiber fineness below 0.1 den. position on the front side (L3) and back side (L1). Then the above yarns and the polyester filament yarn with its fineness 1.5-3.0 den. which is placed inner side (L2) are knitted to form tricot fabric. In that knitting process, the inner yarn and front yarn must be unidirectional, and at least one of two yarns which constitute the front and back side must be knitted in open structure. The resulting tricot fabric is raised, dyed and coated with polyurethane to form artificial leather which features excellent appearance and dimensional stability.

Description

트리코트지(Tricot地) 인공피혁Tricot ground artificial leather

제1도는 본 발명의 인공피혁을 제조하기 위한 트리코트지의 조직의 일례를 나타낸 조직도.1 is a tissue diagram showing an example of the structure of the tricot paper for producing the artificial leather of the present invention.

본 발명은 외관 및 형태 안정성이 우수한 트리코트지 인공피혁에 관한 것이다.The present invention relates to a tricot artificial leather excellent in appearance and shape stability.

즉, 본 발명은 0.1데니어 이하의 초극세 나이론 및 폴리에스터 복합사 및 1.5 내지 3.0데니어의 폴리에스터 필라멘트사를 이용하여 편직된 트리코트지를 기모-염색-플리우레탄 코팅 가공공정을 거쳐 수득되는 외관 및 형태 안정성이 우수한 트리코트지 인공피혁에 관한 것이다.That is, the present invention is the appearance and shape obtained through the process of brushed-dyed-polyurethane coating of tricot paper knitted using ultra-fine nylon and polyester composite yarn of 0.1 denier or less and polyester filament yarn of 1.5 to 3.0 denier It relates to a tricot paper artificial leather with excellent stability.

일반적으로 0.1데니어 이하의 초극세사를 이용하여 제조되는 인공피혁에는 부직포 타입(Nonwoven Type), 트리코프 타입(Tricot Type), 직물 타입(Woven Type)등이 있다. 이러한 여러가지 인공피혁중 부직포 타입 및 직물타입에 대한 제조기술은 다수 제안되어 널리 사용되고 있으나 트리코프 타입의 인공피혁의 제조에 관한 기술은 제품의 외관 및 형태 안정성의 문제점으로 인하여 제조 기술의 향상이 요구되어 왔다.In general, artificial leather manufactured using ultra-fine fibers of 0.1 denier or less include nonwoven type, non-woven type, tricot type, and woven type. Among these various artificial leathers, a number of manufacturing techniques for non-woven fabric types and fabric types have been proposed and widely used. However, the technology related to the manufacturing of Trikov-type artificial leather is required to be improved due to problems in appearance and shape stability of the product. come.

즉, 종래의 경우 트리코트 타입의 인공피혁에 있어서 문제점으로 지적되어온 점은 촉감 및 기모불량, 조직보임등의 외관적인면과 가공시의 폭축(幅縮)으로 인한 셀베이지(Selvage) 말림현상 즉, 형태 안정성에 관한 것이었다.In other words, in the conventional case, the tricot-type artificial leather has been pointed out as a problem because of the appearance of selvage curling due to the appearance of touch, brushing, and the appearance of tissue and the shrinkage during processing. , Shape stability.

따라서 본 발명은 종래의 트리코프 타입의 인공피혁에서 문제점으로 지적되어 왔던 외관 및 형태 안정성의 불량을 완전히 해소하기 위하여 안출된 것으로 상세히 설명하면 다음과 같다. 제1도에 도시한 바와 같이 본 발명은 단사섬도가 0.1데니어 이하인 나이론 및 폴리에스터로된 초극세 복합사를 표면(L3) 및 이면(L1)에 도출시키고 단사섬도가 1.5 내지 3.0데니어인 폴리에스터 필라멘트사를 내층부(L2)로 사용하여 편성하되 표면(L3)과 내층부(L2)를 이루는 양원사의 움직임이 동일방향이며, 표면(L3) 또는 이면(L1)을 이루는 원사중 적어도 하나가 오픈조직으로 편성되는 것을 특징으로 하는 트리코트지를 기모-염색-폴리우레탄코틴등 통상의 가공 공정을 거쳐 수득되는 트리코트지 인공피혁에 관한 것이다.Therefore, the present invention is described in detail to solve the defects in appearance and shape stability that has been pointed out as a problem in the conventional tricop type artificial leather as follows. As shown in FIG. 1, the present invention derives an ultrafine composite yarn made of nylon and polyester having a single yarn fineness of 0.1 denier or less on the surface (L 3 ) and the back surface (L 1 ), and has a single yarn fineness of 1.5 to 3.0 denier. The polyester filament yarn is knitted using the inner layer portion L 2 , but the movement of both yarns forming the surface L 3 and the inner layer portion L 2 is in the same direction, and forms the surface L 3 or the rear surface L 1 . The present invention relates to a tricot paper artificial leather obtained through a conventional processing process, such as brushed-dyed-polyurethanecoat, wherein at least one of the yarns is knitted into an open tissue.

일반적으로 인공피혁을 의료용 또는 시트카바등의 비의료용으로 사용하기 위해서는 적절한 강도가 유지되어야 하는데 종래의 0.1데니어 이하의 극세사만으로 제조할 경우 강도저하에 따른 제품의 품질이 떨어지게된다.In general, in order to use artificial leather for medical or non-medical use such as seat cover, the appropriate strength should be maintained, but if the conventional microfibers manufactured with less than 0.1 denier, the quality of the product due to the strength decreases.

따라서 본 발명에서는 이러한 강도저하의 문제점을 극복하기 위하여 예의 검토한 결과 단사섬도가 1.5 내지 3.0데니어인 폴리에스터 필라멘트사를 나이론 및 폴리에스터로된 0.1데니어 이하의 초극세 복합사와 병용하는 방안이 유효함을 알았다.Therefore, in the present invention, in order to overcome the problem of such a decrease in strength, as a result of earnest examination, it is effective to use a polyester filament yarn having a single yarn fineness of 1.5 to 3.0 denier in combination with ultrafine composite yarn of 0.1 denier or less made of nylon and polyester. okay.

본 발명자들은 또한 트리코트 조직을 2바아(Bar) 또는 3바아 조직으로 편직하되 2바아 조직의 경우이면(Back면)에, 3바아 조직의 경우 내층부(중심면)에 1.5 내지 3.0데니어의 폴리에스터 필라멘트사를 사용하여 편성하였으나 결국 2바아 조직의 경우 외관이 거칠어 제품의 품위가 손상되는 문제점이 있음을 알게 되었다.We also knit the tricot tissue into 2 bar or 3 bar tissue, but in the case of 2 bar tissue (Back side) and in the inner layer (center face) of 3 bar tissue, 1.5 to 3.0 denier poly Knitted by using the ester filament yarn, but finally found that there is a problem that the appearance of the product is damaged due to the rough appearance of the two-bar tissue.

따라서 본 발명에서는 3바아 조직에 의한 트리코트 타입의 인공피혁을 제조하되 표면 및 이면부를 초극세사, 내층부를 통상의 폴리에스터사를 병용함으로써 형태 안정성 및 외관이 양호한 제품을 얻을 수가 있음을 확인할 수 있었다.Therefore, in the present invention, the tricoat-type artificial leather was manufactured using a three-bar structure, but it was confirmed that a product having good morphological stability and appearance can be obtained by using ultrafine yarns on the front and back portions and ordinary polyester yarns on the inner layer portion.

본 발명에 따라 제조된 인공피혁은 천연 스웨드와 유사한 외관을 지님으로써 남여 아동복, 신사복, 부인용 코-트 및 스커트 또는 시이트 카버등의 용도로 사용이 가능하다.Artificial leather manufactured according to the present invention has a similar appearance to natural suede, it can be used for the purpose of men and women's children's wear, men's wear, women's coat and skirt or sheet carver.
