It relates to a method for producing a polyethylene terephthalate microfiber circular knitted fabric, characterized in that the dough knitting to 10 and the polyethylene terephthalate microfiber circular knitted fabric thereof.

지금까지 여성용 속옷이나 스판 티셔츠 등에 사용되는 스판 환편직물의 제조에는 주로 나일론 필라멘트사(50∼70데니어)와 스판덱스사(20∼40데니어)를 환편하여 염색, 가공하는 방법이 사용되어 왔다.Until now, in the manufacture of span circular knitted fabrics used in women's underwear, span t-shirts and the like, methods of circularly knitting nylon filament yarn (50 to 70 denier) and spandex yarn (20 to 40 denier) have been used.

스판물은 직물에 비해서 신축성이 크고 장력에 민감하므로, 형태안정성의 확보와 신축성의 유지라는 상반된 요구조건을 동시에 만족시킬 수 있어야 하나, 스판덱스 환편물은 이러한 점에서 불만족스러웠다. 아울러, 나일론 스판덱스 환편물은 산성염료에 의한 스판덱스 오염으로 인하여 세탁견뢰도가 저하되며, 일광견뢰도 또한 우수하지 못하다는 단점을 가지고 있다.Since spans are more elastic and sensitive to tension than fabrics, they must meet the opposite requirements of securing form stability and maintaining elasticity, but spandex circular knitted fabrics were unsatisfactory in this regard. In addition, nylon spandex circular knitted fabric has a disadvantage in that the laundry fastness is lowered due to the spandex contamination by acid dyes, and the light fastness is also not excellent.

한편, 대한민국 특허공개 제 1998-46260호와 대한민국 특허공개 제 2000-2238호는 각각 폴리에스테르와 이용성 폴리에스테르로 이루어진 직편물을 감량하여 극세화하는 방법과 폴리에스테르계 및 폴리아미드계 복합사를 제조하여 직편직하는 방법을 개시하고 있으나, 이와 같은 복합사를 분리하는 경우 두 성분의 불완전한 분리로 인하여 균일한 염색이 어려우며 견뢰도가 저하되는 문제점이 있다.Meanwhile, Korean Patent Publication No. 1998-46260 and Korean Patent Publication No. 2000-2238 reduce the size of a knitted fabric made of polyester and a usable polyester, respectively, and produce a polyester-based and polyamide-based composite yarn. However, a method of knitting a knitted fabric is disclosed. However, when the composite yarn is separated, uniform dyeing is difficult due to incomplete separation of the two components and the fastness of the fasteners is lowered.

또한, 종래의 폴리에틸렌테레프탈레이트 극세사 스판물의 경우에는 외관에 위단과 중앙접힘줄이 나타나며, 고온, 고압염색과 고온 열처리에 따른 스판덱스의 신축회복성 저하 및 승화견뢰도 저하와 같은 여러가지 문제점들을 가지고 있다.In addition, in the case of the conventional polyethylene terephthalate microfiber plate, the upper end and the central fold line appears in appearance, and has various problems such as deterioration of the stretch recovery and sublimation fastness of the spandex due to high temperature, high pressure dyeing and high temperature heat treatment.

본 발명의 목적은 상기와 같은 종래기술의 문제점들을 해결하기 위한 것으로, 폴리에틸렌테레프탈레이트 극세 멀티필라멘트사와 스판덱스 필라멘트사를 싱글환편기에서 편직함으로써, 뒤이은 염색가공 공정에서 생지의 신축회복성 및 승화견뢰도의 저하를 방지하고 최종제품의 우수한 외관을 보장하는 폴리에틸렌테레프탈레이트 극세사 환편직물의 제조방법을 제공하는 것이다.An object of the present invention is to solve the problems of the prior art as described above, by knitting a polyethylene terephthalate ultra-fine multifilament yarn and spandex filament yarn in a single circular knitting machine, the subsequent recovery of the stretch and sublimation fastness of the dough in the dyeing process It is to provide a method for producing a polyethylene terephthalate microfiber circular knitted fabric to prevent degradation and to ensure a good appearance of the final product.

본 발명의 다른 목적은 상기 방법에 의하여 제조된 폴리에틸렌테레프탈레이트 극세사 환편직물을 제공하는 것이다.Another object of the present invention is to provide a polyethylene terephthalate microfiber circular knitted fabric prepared by the above method.

즉, 본 발명은 폴리에틸렌테레프탈레이트 극세사 환편직물의 제조방법에 있어서, 전체섬도 50 내지 80데니어 및 필라멘트수 192 내지 204인 폴리에틸렌테레프탈레이트 극세 멀티필라멘트사와 전체섬도 20 내지 30데니어인 스판덱스 필라멘트사를 구성원사로 사용하여, 싱글환편기에서 상기 폴리에틸렌테레프탈레이트 극세 멀티필라멘트사와 상기 스판덱스 필라멘트사의 환편비율이 88 대 12 내지 90대 10이 되도록 생지를 편직하는 것을 특징으로 하는 폴리에틸렌테레프탈레이트 극세사 환편직물의 제조방법을 제공한다.That is, the present invention is a method for producing a polyethylene terephthalate microfiber circular knitted fabric, the polyethylene terephthalate ultrafine multifilament yarn having a total fineness of 50 to 80 denier and the filament number of 192 to 204 and the spandex filament yarn having a total fineness of 20 to 30 denier Using, to provide a method for producing a polyethylene terephthalate microfiber circular knitted fabric, characterized in that the knitting material so that the ratio of the circular knitting ratio of the polyethylene terephthalate microfiber multifilament yarn and the spandex filament yarn in a single circular knitting machine is 88 to 12 to 90 to 10. .

본 발명의 폴리에틸렌테레프탈레이트 극세사 환편직물의 제조방법은 폴리에틸렌테레프탈레이트 극세 멀티필라멘트사와 스판덱스 필라멘트사를 싱글환편기에서 편직하여 생지를 제조한 다음, 상기 생지를 물패딩하고 열처리한 후, 염색 및 최종 열고정하는 단계를 포함한다.Method for producing a polyethylene terephthalate microfiber circular knitted fabric of the present invention is to produce a dough by knitting a polyethylene terephthalate microfiber multi-filament yarn and spandex filament yarn in a single circular knitting machine, after the water padding and heat treatment, dyeing and final heat setting Steps.

이하, 본 발명을 상세히 설명하고자 한다.Hereinafter, the present invention will be described in detail.

상기 폴리에틸렌테레프탈레이트 극세 멀티필라멘트사와 스판덱스 필라멘트사를 싱글환편기(single circulating knitting machine)에 권취하고, 편침밀도 28본/인치, 코스밀도 50 내지 80본/인치 및 편직속도 10 내지 18rpm인 조건에서 편직하여, 코스밀도 50 내지 80본/인치 및 중량 140 내지 180g/m2인 생지를 수득한다. 이때, 상기 폴리에틸렌테레프탈레이트 극세 멀티필라멘트사와 상기 스판덱스 필라멘트사의 환편비율은 88 대 12 내지 90 대 10이다. 편직된 생지 중의 스판덱스 필라멘트사의 비율이 10 중량%보다 낮으면 생지의 견뢰도는 향상되지만 신축성이 저하되고, 반대로 12 중량%보다 높으면 생지의 신축성은 좋아지지만 견뢰도 저하 및 원단의 코스트 증가와 같은 단점이 초래된다. 또한, 편침밀도와 코스밀도가 상기 범위를 초과하는 경우에는 단위면적당 중량이 높아져 편직물이 타이트해지고 그 결과 신축성이 결여되는 문제가 발생하며, 편침밀도와 코스밀도가 상기 범위 미만인 경우에는 단위면적당 중량이 낮아져 편직물이 느슨해지고 그 결과 가공후 형태안정성이 약해지므로, 편직시 편침밀도 및 코스밀도의 조절이 중요하다.The polyethylene terephthalate ultrafine multifilament yarns and spandex filament yarns are wound in a single circulating knitting machine, and knitted in conditions of knitting needle density of 28 bones / inch, coarse density of 50 to 80 bones / inch, and knitting speed of 10 to 18 rpm. The dough having a coarse density of 50 to 80 bones / inch and a weight of 140 to 180 g / m 2 is obtained. In this case, the circular knitting ratio of the polyethylene terephthalate ultrafine multifilament yarn and the spandex filament yarn is 88 to 12 to 90 to 10. If the ratio of spandex filament yarn in the knitted dough is lower than 10% by weight, the fastness of the dough is improved, but the elasticity is decreased. do. In addition, when the knitting needle density and the coarse density exceed the above ranges, the weight per unit area becomes high, resulting in a problem that the knit fabric becomes tight and, as a result, lack of elasticity. When the knitting needle density and the coarse density are less than the above range, the weight per unit area is increased. Since the knitting becomes loose and the shape stability is weakened after processing, it is important to control the knitting needle density and the coarse density during knitting.

편직이 완료된 생지는 픽업률 85 내지 90%, 온도 80 내지 90℃인 조건하에 물패딩을 행한다. 물패딩 시의 픽업률이 85% 미만이면, 뒤따른 열처리 효율은 우수하나 원단의 촉감이 저하되고, 픽업률이 90%를 초과하면 그 반대로 촉감은 향상되나 열처리 효율이 저하된다. 한편, 본 발명에서와 같이 고온(80∼90℃)에서 물패딩을 행하면, 저온(30∼35℃)에서 물패딩하는 경우에 문제가 되는 생지상태에서의 주름이나 구김이 뒤이은 열처리 공정에서 고정되어 원단의 외관에 손상을 주는 현상을 방지할 수 있다.After the knitting is completed, water padding is performed under conditions of a pickup rate of 85 to 90% and a temperature of 80 to 90 ° C. If the pickup rate at water padding is less than 85%, the subsequent heat treatment efficiency is excellent, but the feel of the fabric is lowered. If the pickup rate is more than 90%, the touch is improved but the heat treatment efficiency is lowered. On the other hand, when water padding is performed at high temperature (80-90 ° C) as in the present invention, it is fixed in the heat treatment process followed by wrinkles or wrinkles in the dough state, which is a problem when water padding at low temperature (30-35 ° C). It can prevent the phenomenon which damages the appearance of the fabric.

상기 물패딩 공정에 이어, 150 내지 200℃, 바람직하게는 175 내지 195℃에서 폭 46 내지 50인치, 오버피드율 10 내지 35%인 조건으로 30초 내지 1분 30초간 생지를 열처리(presetting)하여, 형태안정성과 주름방지를 도모한다. 열처리시 폭이 46인치 미만이면 원단의 뜯김이 발생하기 쉽고 형태안정성이 약화되며, 반대로 폭이 50인치를 초과하면 원단의 신축성이 저하될 수 있다.Following the water padding process, heat treatment (presetting) for 30 seconds to 1 minute and 30 seconds at a condition of 46 to 50 inches wide and 10 to 35% overfeed rate at 150 to 200 ℃, preferably 175 to 195 ℃ Promote form stability and prevent wrinkles. If the width is less than 46 inches during heat treatment, tearing of the fabric is likely to occur, and shape stability is weakened. On the contrary, if the width exceeds 50 inches, the elasticity of the fabric may be degraded.

열처리된 생지를 용량 100 내지 500㎏의 고온고압 액류염색기에서 싸이클타임 50 내지 100초, 승온속도 1℃/분, 강온속도 1.5 내지 2℃/분, 균염온도 100 내지 125℃ 및 균염시간 30 내지 80분인 조건하에, 통상의 분산염료 0.5 내지 2.0%(owf) 및 분산균염조제 0.5 내지 3g/ℓ를 포함하는 pH 4 내지 5인 염액으로 염색한다. 염색후 탈수 공정을 거쳐, 최종적으로 150 내지 200℃에서, 보다 바람직하게는 180 내지 200℃에서 1분 내지 1분 30초 동안 열고정하여 최종 제품, 즉 폴리에틸렌테레프탈레이트 극세사 환편직물을 수득한다.Heat-treated dough in a high-temperature high-pressure liquid dyeing machine with a capacity of 100 to 500 kg cycle time 50 to 100 seconds, temperature increase rate 1 ℃ / min, temperature decrease rate 1.5 to 2 ℃ / min, leveling temperature 100 to 125 ℃ and leveling time 30 to 80 Under powdering conditions, dyeing is performed with a saline solution having a pH of 4 to 5 containing 0.5 to 2.0% (owf) of a conventional disperse dye and 0.5 to 3 g / l of a dispersing bacterium salt preparation. After dyeing, it is dehydrated and finally heat-set at 150 to 200 ° C., more preferably at 180 to 200 ° C. for 1 minute to 1 minute 30 seconds to obtain a final product, ie a polyethylene terephthalate microfiber circular knitted fabric.

상술한 본 발명의 방법에 따라 제조된 폴리에틸렌테레프탈레이트 극세사 환편직물은 신축회복성과 촉감이 좋으며, 견뢰도가 우수하고, 위단 및 중앙접힘줄과 같은 외관상 결점이 방지된다.The polyethylene terephthalate microfiber circular knit fabric prepared according to the method of the present invention described above has good elastic recovery and feel, excellent fastness, and prevents appearance defects such as upper and central folds.
