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

본 발명은 레이온 필라멘트의 강점인 우수한 냉감성과 촉감을 유지하고, 취약점인 강도와 지나친 드레이프성을 폴리에스테르로 보완하고, ONESIDE염색으로 자연스러운 멜란지 효과를 낼 수 있는 냉감성과 강도가 우수한 환편물의 제조방법에 관한 것이다. The present invention relates to a method of manufacturing a circular knitted fabric excellent in cold feeling and strength which can maintain excellent cold feeling and touch which is the strength of a rayon filament, complement a strength of vulnerability and an excessively drapable property with polyester and produce a natural melange effect by ONESIDE dyeing .

본 발명의 환편물의 제조방법에서 사용되는 원사는 레이온―폴리에스테르 커버링사와 20~30d 스판덱스 필라멘트를 사용하는데, 실가닥수 1:1 로 교호로 공급하여 편성하게 된다. The raw yarn used in the method for producing the circular knitted fabric of the present invention uses a rayon-polyester covering yarn and 20 to 30 d spandex filament yarns, which are alternately supplied with a yarn count of 1: 1.

상기 레이온―폴리에스테르 커버링사는 심사로 레이온필라멘트 75~120d/24~30f를 공급하고 상기 심사에 20~75d/12~36f의 폴리에스테르 SD필라멘트를 TM 300∼600의 꼬임수로 커버링한 커버링사를 사용하여 냉감성과 강도를 향상시키게 된다. 심사로 레이온필라멘트 84~120d/24~30f를 사용하여 전체 커버링사의 냉감성 및 촉감을 부여하며, 심사를 커버링하는 커버링사는 20~75d/12~36f의 폴리에스테르 SD필라멘트를 사용하여 강도를 보완하게 된다.The rayon-polyester covering yarn is supplied with rayon filament 75 to 120d / 24 to 30f by screening, and a covering yarn covering 20 to 75d / 12 to 36f polyester SD filaments with a twist number of TM 300 to 600 It is possible to improve the cold feeling and the strength. By using Rayon filament 84 ~ 120d / 24 ~ 30f, the covering feeling of the entire covering yarn is given and the cover covering yarn is covered with 20 ~ 75d / 12 ~ 36f polyester SD filament do.

상기 레이온―폴리에스테르 커버링사는 레이온120d/30f―폴리에스테르20d/12f 커버링사, 레이온75d/24f―폴리에스테르20d/12f 커버링사 중 어느 하나 또는 둘인 것이 바람직한데, 레이온120d/30f―폴리에스테르20d/12f 커버링사 및 레이온75d/24f―폴리에스테르20d/12f 커버링사 중 어느하나만을 사용할 수도 있으며, 전면에는 레이온120d/30f―폴리에스테르20d/12f 커버링사를, 이면에는 레이온75d/24f―폴리에스테르20d/12f 커버링사를 사용할수도 있다.The rayon-polyester covering yarn is preferably one or two of rayon 120d / 30f-polyester 20d / 12f covering yarn and rayon 75d / 24f-polyester 20d / 12f covering yarn, 12f covering yarn and rayon 75d / 24f-polyester 20d / 12f covering yarn may be used. On the front face, rayon 120d / 30f-polyester 20d / 12f covering yarn is used and on the back face rayon 75d / 24f- / 12f covering yarn may be used.

상기 레이온―폴리에스테르 커버링사는 사장력 4~6gf으로, 상기 20~30d 스판덱스 필라멘트는 사장력 2~3gf으로 환편기에 공급되는 것이 바람직한데, 레이온―폴리에스테르 커버링사는 사장력 4gf미만인 경우에는 접사 상태가 불안정하여 장력변동이 생기기 쉬워 위단이 발생하고, 특히 고속 가공성이 부족한 문제점이 발생하며, 6gf초과시에는 마찰저항이 커짐으로 필라멘트 사절이 생기기 쉬운 문제점이 발생할 수 있다.It is preferable that the rayon-polyester covering yarn is supplied to the circular knitting machine at a bending force of 4 to 6 gf and the 20 to 30 d spandex filament is fed to the circular knitting machine at a bending force of 2 to 3 gf. It is unstable and the tension fluctuation tends to occur, causing a top end, in particular, a problem of insufficient high-speed processability. When it exceeds 6 gf, the frictional resistance becomes large, which may cause filament yarn breakage.

본 발명에서 환편하는 조건은 루프장 12~13cm, 환편속도 17~18rpm의 조건으로 32인치/36게이지의 싱글환편기로 환편한다. The conditions for circularity in the present invention are a circular circular knitting machine of 32 inches / 36 gauge under conditions of a loop length of 12 to 13 cm and a circular velocity of 17 to 18 rpm.

본 발명에서 루프장은 편물 제품 형성의 주요 요소로써 동일 조건하에서 루프장이 길수록 원단 밀도가 적어져 루즈(loose)해지고 단위면적당 중량이 낮아지며 원단폭은 넓어진다. 반대로 루프장이 짧을수록 밀도가 많아지며 원단은 타이트(tight)해지고 단위면적당 중량이 높아지며 원단폭이 좁아진다. In the present invention, the loop length is a main component of knitted product formation. Under the same condition, the longer the loop length, the loose density becomes, loose, the weight per unit area decreases, and the fabric width becomes wider. Conversely, the shorter the loop length, the more dense, the fabric becomes tight, the weight per unit area increases, and the fabric width becomes narrower.

따라서 본 발명에서는 루프장을 12~13cm로 조절하여 최적 편물 루프장을 선정하여야 하는데, 루프장 12cm미만에서는 스판덱스의 함량이 많아져 규격된 제품 생산이 어려운 문제점이 발생할 수 있고, 13cm초과시에서는 스판덱스의 사절이 발생할 우려가 있다. Therefore, in the present invention, it is necessary to select the optimum knitted loop length by adjusting the loop length to 12 to 13 cm. When the loft length is less than 12 cm, the spandex content becomes large and it is difficult to produce the standardized product. There is a possibility that envoys will occur.

그러므로 본 발명에 의하면, 레이온 필라멘트의 강점인 우수한 냉감성과 촉감을 유지하고, 취약점인 강도와 지나친 드레이프성을 폴리에스테르로 보완할 수 있으며, ONESIDE염색으로 자연스러운 멜란지 효과를 낼 수 있는 환편물을 제공할 수 있다. Therefore, according to the present invention, it is possible to provide a circular knitted fabric capable of maintaining a good cold feeling and touch, which is the strength of a rayon filament, and capable of complementing the weak point strength and the excessive drape with polyester and achieving a natural melange effect by ONESIDE dyeing .
