Description

이종복합원사로 편직한 통풍성이 우수한 경량편물의 제조방법{Process Of Producing Light Weight Knit Having Excellent Ventilation From Different―Yarns}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of manufacturing a lightweight knitted fabric,

본 발명은 일반섬유와 용해사를 사용하여 편직후, 상기 용해사를 용해하여 이종섬도로 편직된 효과를 얻도록 하는 통풍성이 우수한 경량편물의 제조방법에 관한 것이다.The present invention relates to a method of producing a lightweight knitted fabric excellent in air permeability, which is obtained by kneading ordinary fibers and dissolving yarns and then dissolving the dissolving yarns to obtain an effect of knitting with different fineness.

현재 편물의 제조방법에서 원사의 굵기가 상이한 편물의 편직은 사도입부에 굵기가 상이한 원사를 공급하여 편직하는 방법을 사용하고 있다. In the current method for manufacturing knitted fabrics, yarns having different thicknesses are knitted by supplying yarns differing in thickness to yarn introduction parts.

한편, 최근 섬유업계에서 트랜드추세는 박지화 및 경량화 추세에 있으며 이러한 경량박지제품은 스포츠웨어 시장에서 큰 붐을 이루고 있다. 스포츠웨어 시장은 우수한 고발색성, 반발탄력성, 강도의 특성을 가진 소재를 이용하여 골프웨어용, 바람막이용, 다운프루프용, 등산용, 각종 스포츠제품으로 용도전개가 이루어지고 있다.On the other hand, trend in the textile industry is in the trend of Park Ji Hwa and light weight, and these lightweight products are booming in the sportswear market. The sportswear market has been developed for use in golf wear, windshield, down-proof, mountaineering, and various sports products using materials having excellent color development, resilience, and strength.

이러한 통풍성이 우수한 경량박지편물을 제조하기 위해서는 5~20 데니어정도의 가는실과 150데니어정도의 굵은실을 배열하여 편직하는 것이 좋은데, 상기의 방법으로 편직하는 경우에는 각각의 원사의 강도와 굵기차이로 인해 장력차이와 루프(LOOP)의 크기 차이로 인하여 사절이 발생하여 작업성이 현저히 저하되는 문제점을 안고 있었다. 또한, 편물의 경우는 비교적 통풍성은 우수하지만, 투명감이나 경량성을 부여하기에는 어려움을 겪고있는 실정이다.In order to produce such a lightweight, passable layered knitted fabric, it is preferable to arrange the knitted fabric by arranging a thin yarn of about 5 to 20 denier and a thick yarn of about 150 denier. In the case of knitting by the above method, Due to the tension difference and the difference in the size of the loop (loop), the workability is remarkably deteriorated. Further, in the case of a knitted fabric, although the air permeability is comparatively excellent, it is difficult to impart transparency and light weight.

대한민국특허공개제10-1990-0001901호(1990년02월27일)Korean Patent Publication No. 10-1990-0001901 (February 27, 1990)

그러므로 본 발명에 의하면, 원사의 굵기차이가 현저한 원사를 이용하여 편직하는 경우에 작업성이 현저히 저하하지 않으면서도 편물물성 및 통풍성이 우수한 경량박지편물을 제공하는 것을 기술적과제로 한다. Therefore, it is a technical object of the present invention to provide a lightweight parchment knitted fabric which is excellent in knitted fabric properties and ventilation properties without significantly deteriorating workability when knitting a yarn with a remarkable difference in thickness of yarn.

그러므로 본 발명에 의하면, 극세사와 용해사의 ITY사와 폴리에스테르 원사를 동일한 편물사로 이웃하게 배열하여 경편 또는 위편으로 편직한 후, 수산화나트륨을 함유한 용액 또는 60~100℃의 물로 처리하여 상기 용해사를 용해하는 것을 특징으로 하는 이종복합원사로 편직한 통풍성이 우수한 경량편물의 제조방법이 제공된다.Therefore, according to the present invention, the ITY yarn and the polyester yarn of the microfine yarn and the melt yarn are arranged adjacent to each other with the same knitting yarn and knitted with warp yarns or weft yarns, and then treated with a solution containing sodium hydroxide or water at 60 to 100 ° C, Wherein the knitted fabric is knitted with a heterogeneous composite yarn.

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

본 발명은 용해사를 함유한 복합사 또는 용해사와 일반섬유사를 사용하여 경편 또는 위편으로 편직한 후, 수산화나트륨을 함유한 용액 또는 60~100℃의 물로 처리하여 상기 용해사를 용해하는 것을 특징으로 하는 이종복합원사로 편직한 통풍성이 우수한 경량편물의 제조방법에 관한 것이다.The present invention is characterized in that the kneaded yarn is knitted using a composite yarn or a melt kneaded yarn containing a melt kneading yarn and a general yarn yarn and then the kneaded yarn is treated with a solution containing sodium hydroxide or water at 60 to 100 DEG C to dissolve the melt kneaded yarn The present invention relates to a method of producing a lightweight knitted fabric having excellent air permeability knitted with a heterogeneous composite yarn.

본 발명의 한 예로서 도 1에 도시된 바와 같이 용해사(1)를 함유한 복합사(10) 및 일반섬유사(20)를 사용하여 제편 후, 상기 복합사에 함유된 용해사를 용해하여 편물을 구성하는 일부실의 섬도를 가늘게 하여 이종섬도로 편직된 효과를 얻도을 수 있다.As an example of the present invention, after using a composite yarn 10 and a general fiber yarn 20 containing the melt yarn 1 as shown in Fig. 1, the melt yarn contained in the composite yarn is dissolved It is possible to obtain the effect of knitting into a different fineness by thinning the fineness of one of the fabrics constituting the knitted fabric.

본 발명에서 편물을 편직하기 위해 사용하는 원사는 용해사를 함유한 복합사 또는 용해사와 일반섬유사를 사용하여 편직한다. 일반원사와 용해사를 하나의 동일한 피더(FEEDER)에 동시에 공급하여 제편할 수도 있으며, 도 1에 도시된 바와 같이 상기 용해사를 함유한 복합사(10)는 붉은색으로 표시된 일반섬유(2)와 하늘색으로 표시된 용해사(1)를 복합한 것을 사용할 수도 있다. 즉, 본 발명의 공급원사로 사용하는 원사는 일반섬유(2)와 용해사(1)를 함유한 복합사(10) 및 일반섬유사(20)의 조합과 용해사(1) 및 일반섬유사(20)의 조합이 있을 수 있다.In the present invention, the yarn used for knitting a knitted fabric is knitted using a composite yarn or a melt yarn containing a melt yarn and a general fiber yarn. 1, the composite yarn 10 containing the melt yarn may be produced by mixing the plain yarn 2 marked with a red color, (1) shown in sky blue may be used. That is, the yarn used as the supply source of the present invention is composed of the combination of the composite yarn 10 and the general fiber yarn 20 containing the general fiber 2 and the melt yarn 1 and the combination of the melt yarn 1 and the general fiber yarn 20). ≪ / RTI >

상기 용해사를 함유한 복합사 또는 용해사와 일반섬유사는 경편기 또는 위편기의 사도입부의 하나의 피더(FEEDER)마다 용해사를 함유한 복합사 또는 용해사와 일반섬유사가 가닥수비로 1:3 ~ 1:7로 공급되는 것이 후술할 용해사의 용해에 의한 편물패턴의 다양성을 구현할 수 있어 바람직하다.The composite yarn or the melt yarn and the general fiber yarn containing the melt yarn are mixed yarn or melt yarn and melt fiber yarn containing melt yarn for each feeder of the warp knitting yarn or yarn introduction yarn of the knitting yarn at a ratio of 1: 1: 7 is preferable because it is possible to realize a variety of knitting patterns by dissolving the melting yarn to be described later.

상기 일반섬유는 면, 양모, 마, 나일론, 폴리에스테르, Rayon 중 어느 하나이상인 섬유이며, 상기 일반섬유사는 면사, 양모사, 마사, 나일론필라멘트사, 폴리에스테르필라멘트사, 레이온(Rayon) 중 어느 하나이상인 필라멘트사이며, 상기 용해사는 알칼리 이용성 폴리에스테르사, 폴리비닐알코올(PVA) 섬유, 폴리에틸렌이민(PEI) 섬유, 폴리젖산(PLA, Polylactic Acid))섬유 중 어느 하나이상인 섬유인 것을 사용할 수 있다. 상기 용해사 중 알칼리 이용성 폴리에스테르사는 알칼리에 용해가 되는 폴리에스테르사로서 대한민국특허등록제10-1337606호에 따른 섬유사를 사용할 수도 있다.Wherein the common fiber is one of cotton, wool, hemp, nylon, polyester, and Rayon, and the common fiber is any one of cotton yarn, wool yarn, maraca, nylon filament yarn, polyester filament yarn, And the dissolution yarn is a fiber that is at least one of an alkali-soluble polyester yarn, a polyvinyl alcohol (PVA) fiber, a polyethyleneimine (PEI) fiber, and a polylactic acid (PLA) fiber. Among the above-mentioned dissolution yarns, alkali-soluble polyester yarns may be polyester yarns soluble in alkali, and fiber yarns according to Korean Patent Registration No. 10-1337606 may be used.

상기 복합사는 여러 가지 형태의 복합사를 사용할 수 있는데, 복합방적사, 합연사, 인터레이스(ITY)사, 가연(DTY)사, 커버링(Covering)사 중 어느 하나인 것을 사용할 수 있다. 상기 일반섬유 중 단섬유형태의 일반섬유를 사용하는 경우에는 일반섬유와 용해사를 복합방적한 복합방적사(Core Yarn)를 사용할 수 있으며, 일반섬유가 필라멘트형태인 경우에는 일반섬유와 용해사를 동일구금에서 복합방사한 복합방사필라멘트사, 합연사, 인터레이스(ITY)사, 커버링(Covering)사의 형태로 사용될 수 있다. 또한 하나의 FEEDER에 일반원사(폴리에스테르, 나일론) 세섬도원사(30D이하)와 용해사(50~150D)를 동시에 공급하여 제편하여도 동일한 효과를 낼수 있다. 예를들면, 면섬유와 알칼리 이용성 폴리에스테르사의 복합방적사를 사용할 수도 있으며, 폴리에스테르필라멘트와 알칼리 이용성 폴리에스테르사의 합연사, 인터레이스(ITY)사, 가연(DTY)사의 형태로도 적용될 수 있다. 또한 원사의 굵기를 이웃하는 원사의 섬도와 비슷하게 하기 위해서 하나의 급사구에 사용하고자 하는 일반원사와 용해사를 하나의 동일한 FEEDER에 동시에 공급하여 제편하면 같은 효과를 얻을 수 있다. The composite yarn may be a composite yarn of various types, such as a composite yarn, a composite yarn, an interlaced yarn, an interlaced yarn, a DTY yarn, and a covering yarn. In the case of using ordinary fibers in the form of short fibers of the above general fibers, it is possible to use a core yarn in which common fibers and soluble yarns are compounded. If the ordinary fibers are filament type, And may be used in the form of a composite yarn filament yarn composite yarn spun from a detente, a composite twist yarn, an interlaced yarn (ITY yarn), and a covering yarn. In addition, the same effect can be obtained even if three yarns (polyester or nylon) of three yarns (30D or less) and a melt yarn (50 ~ 150D) are supplied simultaneously to one FEEDER. For example, a composite yarn of a cotton fiber and an alkali-use polyester yarn may be used, and the yarn may also be applied in the form of a twist yarn of polyester filament and alkali yarn polyester yarn, an interlaced yarn (ITY yarn), and a false yarn (DTY yarn). In order to make the thickness of the yarn to be similar to that of the neighboring yarn, it is possible to obtain the same effect by simultaneously supplying the common yarn and the melt yarn to one feeder at the same feeder.

또한, 150d/72필라의 폴리에스테르 원사를 사용하는 경우에 극세사 (20d/24필라. 5d/4필라)와 용해사(알칼리 이용성 폴리에스테르사)의 ITY사를 동일한 편물사로 이웃하게 배열함으로써 비슷한 섬도의 폴리에스테르원사와 ITY복합사를 교호로 피더에 공급하여 편직할 수 있다. In addition, when polyester yarn of 150 d / 72 pillar is used, ITY yarns of microfiber (20 d / 24 pillar, 5 d / 4 pillar) and melting yarn (alkali utilizable polyester yarn) The polyester yarn and the ITY composite yarn can be alternately supplied to the feeder to be knitted.

이렇게 일반섬유사와 용해사를 함유한 복합사를 교호로 배열하여 편직하게 되면 일반섬유와 복합사간의 섬도차이가 크지 않아 편직시 장력차이가 발생하지 않고, 편성시 발생되는 각종 마찰에 견디기 쉽기 때문에 사절이 발생하지 않게 되는 장점이 있다. When the composite yarns including the plain fiber yarn and the soluble yarn are arranged alternately and knitted, the difference in fineness between the plain fiber and the composite yarn is not large, so that there is no difference in tension at the time of knitting, There is an advantage in that it does not occur.

상기 편직된 편물은 수산화나트륨을 함유한 용액 또는 60~100℃의 물로 처리하여 상기 복합사에 함유된 용해사를 용해한다. 상기 용해사가 온수(물)에 의해 용융되는 수용성 고분자 섬유인 경우에는 60~100℃의 물로 처리함으로써 복합사에 함유된 용해사를 용융시킬 수 있다. The knitted fabric is treated with a solution containing sodium hydroxide or water at 60 to 100 DEG C to dissolve the soluble yarn contained in the composite yarn. When the dissolving yarn is a water-soluble polymeric fiber that is melted by hot water (water), it is possible to melt the dissolved yarn contained in the composite yarn by treating with water at 60 to 100 ° C.

만일, 용해사(1)만을 일반섬유사(20)와 교호로 피더에 각각 공급하여 제편을 하고 수산화나트륨을 함유한 용액 또는 60~100℃의 물로 처리할 경우 편성된 루프 중 용해사(1)가 녹아 없어지게 되어 루프(Loop)부분의 실이 빠지게 되고 편성된 부분이 풀어져서 편물을 형성할 수 없게 된다.If only the melt yarn 1 is supplied to the feeder alternately with the ordinary fiber yarn 20 and the solution is treated with a solution containing sodium hydroxide or with water at 60 to 100 ° C, The loose yarn is loosened, and the knitted fabric is loosened, so that the knitted fabric can not be formed.

이렇게 제조된 편물 중 상기 용해사부분의 용해처리에 의해 일반섬유부분만 잔존하게 된다. 이렇게 잔존한 원사의 섬도는 제편시보다 급격히 가늘어지게 되어 공간성을 부여할 수 있으며, 가는실의 다양한 배열사를 적용하게 되어 경량박지화가 가능할 뿐만 아니라 통풍성도 우수하며, 편물패턴의 다양성을 부여하게 되는 것이다.Only the ordinary fiber portion remains by the dissolving treatment of the melt yarn among the knitted fabrics thus produced. The fineness of the remaining yarn is sharply lower than that of the yarn, so that space can be imparted. Also, various arrangements of fine yarns can be applied, thereby making it possible to provide a lightweight knitted fabric with excellent ventilation and a variety of knitted patterns will be.

그러므로 본 발명에 의하면, 일반원사와 지극히 가는실을 배열로 사용한 효과외에 용해사와 일반원사가 복합된 복합사에서 용해사가 차지하는 공간이 녹아서 빈공간이 남아 있기 때문에 통풍성이 우수하다, 뿐만 아니라 다양한 Pattern을 부여할 수가 있기 때문에 다양한 제품전개가 가능하며 용해사의 용해후 가는 실이 남아있어서 은은한 투명감을 부여할 수 있다. Therefore, according to the present invention, in addition to the effect of using an ordinary yarn and an extremely fine yarn in an arrangement, the space occupied by the melt yarn in the composite yarn in which the melt yarn and the general yarn are combined is excellent, It is possible to develop various products and it is possible to impart a clear feeling of transparency because fine threads remain after melting of the dissolving yarn.
