The present invention relates to a method of manufacturing a knit for preventing fluff formation and deformation, and more particularly, to a method of manufacturing a knitted fabric by sequentially supplying a first yarn and a second yarn and forming a first needle array and a second needle array The first yarn and the second yarn are looped so as to be caught by the respective needles of the first needle array and the second needle array so that the first and second needle arrays are sequentially operated, The present invention relates to a method of manufacturing a knit for preventing fluff formation and shape deformation which raises a yarn and a second yarn to form a continuous ring in a transverse direction, and a knit garment produced by this method.

Knitwear has good warmth and softness, and various patterns can be expressed according to the method of knitting, and demand is steadily increasing. In general, knitwear has been mostly preferred for winter clothing, but recently it has been consuming various knitwear regardless of the season. Knitwear is more active than clothing made from textiles, and its consumption is growing not only in the sports market but also in the casual market.

However, knitwear causes shrinkage during washing, and as the wear is repeated, the number of lint or shape increases. In order to compensate for this, knit fabrics are variously processed, and Japanese Patent No. 10-1439487 discloses processing knit fabrics to improve the morphological stability of knitwear and soften the surface. However, during the process of wearing and washing the knitted fabric, the effect of the processing may be weakened and the knitwear may be stretched or fluffy.

Therefore, it is required to develop knitted and knitted garments that can prevent shape deformation and fluff formation of knitwear without a back-up process.

As shown in FIG. 1, a first yarn 1211 and a second yarn 1221 are sequentially supplied in order to produce a knit according to an embodiment of the present invention (S1100). In order to prevent sagging of the produced knitted fabric and to reduce occurrence of fluff, the present invention uses two types of yarns other than one yarn to knit.

The first yarn 1211 is an AW yarn. AW is a blend of wool and acrylic blended with synthetic fibers to make the best of wool and acrylic. Compared to normal wool, it has less brushed texture, is softer, and has a smooth texture. AW produces sharper colors compared to wool when dyeing, and less shrunk or lint when making knitted fabrics. Depending on the degree of mixing of wool and acrylic, the feel and weight of the yarn varies. In the present embodiment, 90 to 110 parts by weight of acrylic is mixed with 100 parts by weight of wool, but the present invention is not limited thereto. The first yarn 1211 has a number of 55 and the twist constant is 630 to 680. 'Number' is a unit of fiber, which indicates how much length can be drawn based on the weight of the fiber. The higher the number, the thinner the thread is, and in the case of natural fibers, it is expressed in units of 'number'. The twist constant is the degree of twist that is imparted to impart strength to the yarn.

The properties of the yarn surface vary depending on the yarn twist constant. That is, the higher the twist constant of the yarn is, the less lint is produced, but the surface of the yarn becomes rough and the surface of the knit fabric becomes rusty and uneven. This results in a deterioration of feeling in production of clothes. On the contrary, if the twist constant of the yarn is low, the knitted fabric produced is good in feel and feeling, but it is likely to cause a lot of fluff and deform the shape of the garment easily. In this embodiment, a yarn having a twist constant of 630 to 680 was used as the first yarn to reduce the occurrence of fluff and to improve the feel and feel of the knitted garment.

The second yarn 1221 uses a polyester filament yarn. The polyester filament yarn is continuous yarn, and the shape of the fibers is long and continuous. The polyester filament yarn has a small thickness and a high strength, thereby improving the durability of the knitted fabric. The second yarn 1221 may be a filament yarn of 75 denier or 100 denier. 'Denia' is the basis of the weight of fiber for drawing a certain length of fiber and is mainly used as a unit of synthetic fiber. The larger the denier, the thicker the thread.

As shown in FIG. 2, the first yarn 1211 and the second yarn 1221 are supplied to the knitting machine by a yarn carrier, and the first yarn 1211 is supplied before the second yarn 1221. The yarn carrier 1200 has a supply port for supplying two kinds of yarns, and the first yarn 1211 and the second yarn 1221 are supplied through the supply port. The supply port through which the first yarn 1211 is fed is located in the front side in the traveling direction, and supplies the first yarn 1211 to the apparatus. The supply port through which the second yarn 1221 is supplied is located at the rear portion in the traveling direction so that the second yarn 1221 is positioned at the lower portion of the first yarn 1211.

As shown in FIG. 3, the diameter of the first yarn 1211 is thicker than that of the second yarn 1221. The first yarn 1211 is thicker than the second yarn 1221 so that the second yarn 1221 is completely covered by the first yarn 1211 and is not exposed to the outside. The thickness of the first yarn 1211 may be formed to be 2 to 3 times that of the second yarn 1221 and knitted. In this embodiment, the thickness of the first yarn 1211 is 1 mm, and the thickness of the second yarn 1221 is 0.5 mm.

Next, the first needle array and the second needle array are aligned (S1200). A weft knitting machine has a plurality of needles arranged in a straight line, and the yarn is knitted while moving left and right. As shown in FIG. 4, a plurality of needles are distinguished into a first needle array 1110 and a second needle array 1120. The first and second needle arrays 1110 and 1120 may be used and the first needle array 1110 may be used according to a knitting method. In this embodiment, the first needle array 1110 and the second needle array 1120 are all knitted (Full needle stitch). The first and second needle arrays 1110 and 1120 are aligned so that the first yarn 1211 and the second yarn 1221 are engaged. In another embodiment, only the first needle array can be used to knit (Plain stitch).

The first yarn 1211 and the second yarn 1221 are caught by the respective needles of the first needle array and the second needle array 1110 and 1120 (S1300). As shown in FIG. 5, the first yarn 1211 and the second yarn 1221 are overlapped in the vertical direction, and the first yarn 1211 is located at the upper portion. As shown in Fig. 5, each of the needles is hooked on the needle ends by overlapping first and second yarns 1211, 1221 to form a loop. The second yarn 1221 is covered by the first yarn 1211 due to the difference in thickness of the first and second yarns 1211 and 1221. [

As shown in FIG. 7, when the first and second yarns 1211 and 1221 are caught by the first and second needle arrays 1110 and 1120, the first yarn 1211 is positioned on the upper part of the loop , And the second yarn 1221 is not exposed to the outside. The second yarn 1221 is made of polyester yarn and has high strength so as to impart durability to the knitted garment, but is not exposed to the outside, so that it is possible to maintain the unique touch of the knit.

In another embodiment, the second yarn 1221 may be formed of a plurality of thin fibers to reduce the weight of the yarn while increasing the strength of the second yarn. Thus, it is possible to reduce the weight feeling while improving the original quality of the knit garment. For example, yarns of 20 denier can be used in two layers. When the second yarn 1221 is formed of a plurality of fine fibers, the second yarn 1221 is hardened by the steam applied after the production of the knitted or knitted garment, so that the fibers of the first yarn 1211 can be caught more . This makes it possible to more effectively prevent the occurrence of shape deformation and fluff.

In another embodiment, the shape of the cross section of the second yarn 1221 may be elliptical rather than circular. The second yarn 1221 may be formed flat on the inner surface of the first yarn 1211 so as to have a wider surface area. In this case, the second yarn 1221 is hardened by the steam applied after the production of the knitted or knitted garment, so that more fibers of the first yarn 1211 can be caught.

The first and second needle arrays 1110 and 1120 sequentially drive the first yarn 1211 and the second yarn 1221 to form a continuous continuous ring in step S1400. As shown in Fig. 8, knit is formed by continuous ring formation, and the knitted portion moves downward. The knitted fabric may be weighted so that the knitted fabric maintains a uniform tension. A knitted fabric is manufactured according to the shape and size of each piece of the knitted garment to be produced. If you need to reduce the number of knitted noses, such as a retail mountain, reduce the nose by transferring the nose to the side.

When knit is completed, high temperature steam is applied so that the second yarn 1221 is more closely attached to the first yarn 1211. The second yarn 1221 is tightened by the high-temperature steam and tightly adhered to the first yarn 1211 to prevent the fibers from being discharged from the first yarn 1211 to generate fluff. The knit according to the present invention has a soft touch feeling unique to the AW yarn even though the AW yarn is exposed only on the surface thereof. In addition, the polyester filament yarn in the AW yarn more firmly supports the AW yarn to maintain the knit shape and prevent fluff . The process of applying steam may be performed after knit garment production.

FIG. 9 is a view showing a front plate and a rear plate in a knit garment according to an embodiment of the present invention, FIG. 10 is a view showing a coupling part in a knit garment according to an embodiment of the present invention, In the knit garment according to the second embodiment of the present invention.

Fig. 9 shows a knit knitted by the knit making method of the present invention. The front plate 2110 and the back plate 2120 are knitted. The front plate 2110 and the back plate 2120 are made to face each other and then the shoulder line and the side line are stitched together. In order to further strengthen the staple, sewing is carried out using a hippo sewing machine. The sufa sewing is made by using four yarns, and the stitching is not easily released.

And the stitched area of the shoulder line and the side line is referred to as an engaging portion 2210. As shown in FIG. 10, the engaging portion 2210 performs an overrock for end treatment. The elastic member 2220 may be inserted to prevent the engagement portion 2210 from being slackened during the overlock process. As the elastic member 2220, an elastic tape such as silicone or rubber may be used. After the elastic member is attached to the end of the engaging portion 2210 during overlock sewing, the front plate 1220 and the back plate 2120 are subjected to overlock treatment. The shoulder line can easily be worn for a long period of time or when the activity is large. The shoulder line in the clothes affects the impression of the clothes, so it is not good that the shoulder line is stretched. The present invention can prevent the shoulder line from being slackened by shortening the life of the knitted garment by sticking the tape to the end of the engaging portion 2210 and performing the overlock treatment with the tape. On the other hand, an elastic yarn such as lanolin yarn or urethane yarn can be used for overkilling. In this case, even if the clothes are stretched, there is no fear that the sewing thread will be torn.

In other embodiments, instead of applying tape, an elastic composition may be applied. An elastic composition is applied to the joint portion and then hardened to prevent the knit from sagging. As the elastic composition, a compound of silicone and silicone rubber may be used, and the coating thickness of the elastic composition may be 1 to 2 mm. When the elastic composition is applied, it can be applied precisely only in a necessary area.

Sew the front and back plates, process the ends after overlocking. In the present embodiment, end treatment is performed on neckline, vibration, and hem. For end treatment, as shown in Fig. 11 (a), a new annular portion is formed near the end. A loop is formed (coiling) for each row of knitted fabrics to form a new stage. And the knitted fabric is knitted again from the formed knot to form a knife (shirbor). 11 (b)). When the knitting is completed, the knitted fabric is folded inward (Fig. 11 (c)). The knitting of the knitting machine is knitted by a method of knitting with good elasticity. For example, in the case of a neckline or a circumference of a vibration, it can be knitted with a rubber knot or the like.

When the clothes are finished, the knitted clothes are given high temperature steam. The second yarn 1221 is further brought into close contact with the first yarn 1211 by the high temperature steam to prevent the fibers from escaping from the first yarn 1211 to generate fluff. In the knitted garment according to the present invention, only the AW is exposed on the surface, and the polyester filament yarn in the AW yarn supports the AW yarn more firmly in the inside of the AW yarn to maintain the knit shape and prevent the fluff can do.

In forming a knit, the present invention can knit a polyester filament yarn by overlapping with an AW yarn, thereby preventing slackening of the knit and minimizing the occurrence of fluff. Further, the thickness of the polyester filament yarn is made narrower than that of the AW yarn, so that the polyester filament yarn is completely covered by the AW yarn, and the polyester filament yarn is not exposed to the outside. As a result, the polyester filament yarn is used, and it does not hinder the feeling of knit or feeling of use.

It should be noted that the embodiments of the present invention disclosed in the present specification and drawings are only illustrative of the present invention in order to facilitate description of the present invention and to facilitate understanding of the present invention and are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.
