The present invention relates to a tubular knitted fabric having an opening on the end side of knitting such as gloves or socks and a knitting method thereof.

Gloves or socks which are tubular knitted fabrics are generally knitted into a tubular shape from a finger tip or a toe when knitted using a flat knitting machine. In the case of a glove or a sock having a finger portion (including the toe portion, the same below), each finger portion is knitted from the tip of the finger to the finger joint portion, and then each finger portion is joined to form a cylindrical body. .

As for the main body part of a sock or a glove, the insertion opening of a foot or a hand becomes a knitting end side. This knitting finish part is subjected to an anti-loosening treatment. What is generally done as this anti-loosening treatment is a method of overcasting the opening on the knitting end side by an overlock machine. After overcasting by this pusher sewing machine, usually, an invisible stitch is used for the final processing of the opening by sewing machine.

However, the anti-loosening treatment by pusher box sewing machine takes time to finish, since complete automation is impossible and sewing operation by the operator is required. In addition, since the loosening is likely to occur when the transfer to the sewing machine processing step, the portion to be discarded in consideration of some loosening is knitted.

Here, what is described in patent document 1 is proposed as a method of automating an anti-loosening process. In patent document 1, when the opening end is knitted, a male course including the final course is knitted by a yarn having heat sealability, and the knitted fabric is knitted from the knitting machine after the final course is knitted. The technique which melt | dissolves a heat-sealing seal | sticker by removing and heat-processing, and solidifies an edge part is disclosed. However, if the anti-loosening treatment is performed using a heat sealable seal, when the heat sealable seal melts and solidifies, the edge of the opening is hardened and elasticity is not obtained, and the opening becomes hard when a glove or the like is attached. There are also inconveniences, such as being easy to hurt the skin.

Moreover, what is described in patent document 2 is also proposed as a method of automating an anti-loosening process. In Patent Literature 2, the vicinity of the opening end is knitted with a yarn having elasticity, and the final course of the opening is knitted into a yarn in which a loop is formed in the shape of a protrusion around a screen, for example. A technique for preventing loosening is disclosed by winding a projection part of a bowel in an elastic thread.

In the anti-loosening treatment of Patent Literature 2, the feel of the opening can be softened. However, since the yarn is deliberately changed into elastic yarn after knitting, the yarn is changed to a separate yarn again and knitted. In addition, since the bow is made of a special configuration, it is expensive and it is impossible to arrange the part of the projection at a predetermined position regularly and accurately so as to protrude from the loop of the previous course.

Here, the applicant uses a special yarn in which a small amount of heat sealable yarn is mixed with a heat-shrinkable yarn, and after knitting the open ends of gloves and the like with this special yarn, The technique which removes from a knitting machine and heat-processes at the temperature which melt | dissolves only a heat-sealable yarn without melt | dissolving a heat-shrinkable yarn is proposed (refer patent document 3).

The anti-loosening treatment method disclosed in Patent Literature 3 shrinks the heat shrinkable yarn in a special yarn by heat-treating the open end of the knitted fabric at the above temperature, and partially stitches the stitch knitted with the special yarn into a heat sealable yarn. The opening end is prevented from loosening so as to adhere.

By carrying out the anti-loosening treatment with the special thread shown in patent document 3, the elasticity of the opening edge part of a knitted fabric can be maintained, and an opening can be prevented without becoming too hard.

Patent Document 1: Japanese Unexamined Patent Publication No. 51-122532

Patent Document 2: Japanese Unexamined Patent Publication No. 51-122531

Patent Document 3 Japanese Patent Application Publication No. 64-2700

However, the special yarn used for the anti-loosening treatment disclosed in Patent Document 3 is more expensive than a commercially available covering yarn (filament twist yarn: FTV) because of its special structure. Is higher. In addition, even when the opening end is knitted using a special thread, it is necessary to provide a yarn feeding port for a special thread separately from the yarn feeding port for knitting used for knitting the main body portion. In addition, the special yarn melts the heat sealable yarn, which is a part thereof, and adheres the yarn to the yarn, so that the melt-solidified portion still gives a hard touch.

The present invention is a cylindrical knitted fabric having an opening on the end side of the knitting, which can be reliably prevented from loosening of the opening end at low cost because it does not increase the feeding port by using a stretch yarn having a good feel and a low price. It is an object to provide a method for organizing the same.

The cylindrical knitted fabric of the present invention is a cylindrical knitted fabric which is knitted using a flat knitting machine having a pair of front and rear needle beds, and has an opening at the end of the knitting. And the knitted fabric main body of the cylindrical knitted fabric of this invention is formed in a cylindrical shape by the injection knitting and the plating knitting which knits by supplying the elastic yarn to the knitting needle simultaneously. The openings formed on the end side of the knitting knitted body main body are knitted at least one course with a stitch density smaller than the stitch density at the time of the plating knitting using only the yarn after the knitting course, which is knitted by scanning and stitching. The small loop knitted fabric portion formed by the small loop of the stitched stitch, and the final course portion knitted with a stitch density larger than the stitch density when the small loop knitted fabric portion is knitted using only the yarns following the small loop knitted fabric portion have.

Plating knitting refers to a front stitch formed by supplying a needle that is a surface yarn and a yarn that is a back yarn to a knitting needle simultaneously. It is a technique in which an injection appears on the surface and the coarse is organized to hide behind it. In the case of knitting socks and gloves, plating knitting may be performed.In this case, elastic yarns such as filament, twist yarn, etc. are incorporated into the yarn for scanning, so that the elasticity of the knitted fabric is increased. .

Plating is knitted while using the injection yarn for injection and the yarn for feeding, so that the yarn for injection is placed at a position slightly retracted in the direction of travel with respect to the yarn for injection. do.

As the scan, a yarn having a low elasticity formed of a material such as cotton, wool, silk, or synthetic fiber is used.

As the fine yarn, a yarn in which a microfilament is spirally wound around an elastic yarn such as a polyurethane yarn, for example, a single covered yarn (SCC) or a double covered yarn of FTV. yarn) (DCV), etc. are mentioned. Also, as the fine yarn, the polyurethane yarn is covered with roving and slubbing of cotton, wool, synthetic fibers, etc., while the polyurethane fiber is drafted under an appropriate tension during the weaving process. The polyurethane yarn may be a yarn having a core structure (cored yarn) obtained by twisting the polyurethane yarn and the irradiation for coating. The fine yarn used in the present invention may have elasticity in the screening, It is preferable to have a configuration in which the covered yarn is in a relaxed state by shrinkage of the examination, and when the covered yarn is in a relaxed state around the examination, the covering yarn is in a state that is widened outward in the radial direction, and thus the stitch is knitted. When this bulge becomes resistance, it becomes easy to get entangled in a thread, and the omission of a loop is hard to occur The.

It is also preferable that the small loop knitted fabric portion is knitted to have a tuck loop. The tuck loop may appear alternately with the knit loop in the course direction, or the tuck loop may be knitted on the way while knitting the plurality of knit loops continuously in the course direction. In the case of forming the tuck loop, it is preferable to form a large loop in the final course portion in the tuck loop.

Moreover, the cylindrical knitted fabric provided with the opening part at the end of the knitting of this invention can be knitted by the following knitting processes using the flat knitting machine provided with a pair of front and back needle beds. The process of knitting the main body of the knitted fabric by the knitting of the plate and feeding and feeding the elastic yarn to the knitting needle at the same time, and the plate using only the yarn to continue in the knitting course composed by the injection and the yarn A process of knitting a small loop knitted fabric formed by a small loop of stitches by knitting at least one course at a stitch density smaller than the stitch density at the time of knitting, and knitting the small loop knitted fabric portion using only the yarn following this small loop knitted fabric portion It is a process of forming a final course with a stitch density larger than the stitch density at the time of making.

In the case where the tuck loop is formed in the small loop knitted fabric portion, the step of knitting the small loop knitted fabric portion is knitted to include the knitting forming the tuck loop.

(Example)

Next, a preferred embodiment of the present invention will be described in detail below with reference to the drawings. The embodiment shown below includes a pair of front and rear needle beds extending in the left and right directions and facing each other in the front and rear directions, and the rear needle bed is rackable from side to side and stitched between the front and rear needle beds. The sock and the knitting method of the two-bed flat knitting machine, which can be moved by, are shown. This embodiment shows the structure of the opening end in a foot insertion port, and the knitting method of this opening end in the case where knitting starts on the toe side and finishes knitting at the foot insertion port.

The example shown below is a foot when knitted so that a socks can be knitted from a toe by a plating knitting, and a heel part and an ankle part are knitted in succession, and then knitted so as to finish knitting at a foot opening (opening part). The structure of the opening end of an insertion opening and the knitting method of the opening end of this foot insertion opening are shown.

The flat knitting machine of the two-bed bed used by each Example used the flat knitting machine of the SP10 gauge manufactured by Shima Seiki Co., Ltd. In addition, the knitted fabric main body of the socks knitted in each Example was knitted by the stitch density 70 in the 0-90 step | paragraph which is a setting range which can set the stitch density at the time of knitting. Here, the stitch knitted with the knitting machine becomes larger as the stitch density is larger.

In the socks knit in each example, the front knitted fabric serving as the foot knitted fabric was knitted mainly by the front needle bed F, and the back knitted fabric serving as the sole side was mainly knitted by the rear needle bed B.

In the present embodiment, the toe part, the heel part, the ankle part, and the part of the foot other than the opening end at the foot insertion port are used as the knitted fabric body, and the knitted fabric body is scanned in each embodiment. And by adding the coarse (편) at the same time to form a knitting knitted knitting.

In each example, the injection is made of cotton yarn of two folded yarns (two ply yarns) and 30 yarns (30 yarn number count 30). (芯 絲) consisting of 20 to 40 denier elastic yarns (polyurethane yarn, etc.), covering yarns spirally wound around the screening (filaments such as polyester fibers and polyamide fibers) An FTV made of this 70 denier yarn was used.

≪ Embodiment 1 >

Fig. 1 shows a planar loop diagram of a part of the opening end at the foot insertion hole of the sock. Fig. 2 shows a knitting process diagram when knitting the opening end of the foot insertion port of the sock according to the present embodiment.

In each of the loop diagrams and the knitting process diagrams of the first and second embodiments, stitches formed by the plating knitting for superimposing the scans and the yarns are shown by thick lines, and stitches formed only by the yarns are shown by thin lines.

In the knitting process diagram of Fig. 2 and the knitting process diagrams of Figs. 4 and 5 described later, the numerals on the left represent the steps of the knitting process, the F on the left represents the front needle bed, the B the rear needle bed, and the arrows The steeping direction is shown, respectively.

In this embodiment, the knitted fabric main body 1 of the cylindrical knitted fabric is knitted into a cylindrical shape by plating knitting using the scanning 2 and the fine yarn 3. Then, at the opening end of the foot insertion port formed on the end of the knitting fabric main body 1, the small loop knitted fabric portion 4 knitted using only the yarn 3, and the last of the small loop knitted fabric portion 4, followed by only the fine yarn 3 knitted Course part 5 was formed. The small loop knitted fabric portion 4 was knitted following the knitting course formed by the injection 2 and the fine yarn 3.

The small loop knitted fabric portion 4 was formed by knitting one course with a stitch density 35 smaller than the stitch density 70 at the time of plating knitting. Since the small loop knitted fabric portion 4 makes the stitch density smaller than when the knitted fabric body 1 is knitted, the stitch is smaller than the stitch of the knitted fabric body 1, and the stitch is formed smaller.

The final course portion 5 which is knitted following the small loop knitted fabric portion 4 is knitted one course with a stitch density 75 greater than the stitch density 35 when the small loop knitted fabric portion 4 is used as it is and the small loop knitted fabric portion 4 is used as it is. Is formed. Since the last course part 5 makes the stitch density larger than when knitting the small-loop knitted fabric part 4, the nose is larger than the stitch of the small-loop knitted fabric part 4, and a loop is formed large. As shown in Fig. 1, the stitch forming the final course portion 5 is in a state in which a large loop in which the sinker side is tightened is formed in the stitch of the small loop knitted fabric portion 4.

Next, a knitting method of the small loop knitted fabric portion 4 and the final course portion 5, which are continuously formed on the knitted fabric body 1, will be described based on the knitting process diagram of FIG.

In Fig. 2, step S shows a state in which each stitch forming the knitted fabric main body 1 is coupled to the needle of the front needle bed F and the needle of the rear needle bed B, and the knitted fabric main body 1 is in a cylindrical shape by these stitches. The state in which it is organized is shown.

Step 1 shows a step of knitting the final course of the rear side knitted fabric in the knitted fabric body 1 by the back knitting into the back needle bed B. Step 2 shows the process of the knitted fabric body 1 by the plating. The process of knitting the final course of the front knitted fabric into the front needle bed F is shown. This plating was knitted with a stitch density of 70.

From the plating knit using scan 2 and the yarn 3 to knitting using only yarn 3, knitting the back side knitted fabric by using only yarn 3 to continue the stitch of the body 1 knitted by steps 1 and 2 After that (step 3), the front knitted fabric was knitted one course (step 4) to form the small loop knitted fabric portion 4. The stitches of the small loop knitted fabric portion 4 were knitted with a stitch density of 35 to form stitches smaller than the stitches of the knitted fabric body 1. If the stitch density is too small, such as 5 or less, the tension is excessively applied to the extra thread 3, and the opening end of the foot insertion port becomes in a state of high resistance when worn, which may cause breakage of the thread.

In order to continue the stitches of the small loop knitted fabric portion 4 knitted in Steps 3 and 4, the rear knitted fabric is knitted one course using only the yarn 3 (step 5), and then the front knitted fabric is knitted one course (step 6). ) The final course part 5 was formed. The final course portion 5 was knitted at a stitch density of 75 to form a large loop.

In the present embodiment, the stitch of the knitted fabric main body 1 is thickened by two threads of scanning 2 and fine yarn 3, so that when the small stitch of the small loop knitted fabric portion 4 is formed on the stitch formed of this thick thread, the opening of this small stitch is formed. The area is reduced by the coarse thread of the knitted fabric body 1. Since a large loop of the final course portion 5 was continuously formed in a small stitch of the opening area, the large loop is in a state where the sinker loop side is tightened by a small loop of the small loop knitted fabric portion 4, Large loops are difficult to get out of the small loop. As a result, the opening end formed in the small loop knitted fabric portion 4 and the final course portion 5 becomes difficult to be released.

≪ Embodiment 2 >

3 is a view showing a planar loop diagram of a part of the opening end at the foot insertion port of the sock. 4 and 5 show a knitting process diagram when knitting the open end of the foot insertion port of the sock according to the present embodiment.

Also in this embodiment, the knitted fabric main body 1 was knitted into a cylindrical shape by plating knitting using scan 2 and fine yarn 3. And a small loop knitted fabric portion 4 which is knitted using only the fine yarn 3 after the knitting course formed by the scanning 2 and the fine yarn 3 at the opening end of the foot insertion hole formed on the end side of the knitting fabric main body 1, and the small loop. Subsequent to the knitted fabric portion 4, only the final yarn 3 was used to form the final course portion 5 knitted.

In this embodiment, the small loop knitted fabric portion 4 was formed by knitting four courses with a stitch density 35 smaller than the stitch density 70 at the time of plating knitting. Also in this embodiment, since the small loop knitted fabric portion 4 has a smaller stitch density than when the knitted fabric body 1 is knitted, the loop is smaller than the stitches of the knitted fabric body 1.

In the small loop knitted fabric portion 4 of the second embodiment, all the stitches following the knitted fabric main body 1 were formed by knit loops, and three courses alternately formed knit loops and tuck loops from the following course. In this tuck loop, since the loop is formed by four fine yarns, the opening area becomes very small.

The final course portion 5 which is knitted following the small loop knitted fabric portion 4 is knitted one course with a stitch density 75 greater than the stitch density 35 when the small loop knitted fabric portion 4 is used as it is and the small loop knitted fabric portion 4 is used as it is. It was formed by. Since the final course portion 5 made the stitch density larger than when knitting the small loop knitted fabric portion 4 as in the first embodiment, the nose is larger than the stitch of the small loop knitted fabric portion 4, so that a loop is formed large. As shown in Fig. 1, the loop forming the final course portion 5 is in a state in which a large loop in which the sinker side is tightened by a loop of the small loop knitted fabric portion 4 is formed. In particular, since the large loop of the final course portion 5 that is formed continuously to the tuck loop is tightened further by the tuck loop, the loop of the final course is more difficult to fall out of the stitch of the small loop knitted fabric portion 4.

Next, a knitting method of the small loop knitted fabric portion 4 and the final course portion 5, which is formed continuously on the knitted fabric body 1 according to the second embodiment, will be described based on the knitting process diagrams of FIGS.

In Fig. 4, step S shows a state in which each loop forming the knitted fabric main body 1 is coupled to the needle of the front needle bed F and the needle of the rear needle bed B.

Steps 1 and 2 show a process of knitting the final course of the knitted fabric main body 1 by the plating knitting, and steps 3 and 4 are knitting using only the yarn from the plating knitting using the scanning 2 and the yarn 3 The step of knitting the small loop knitted fabric portion 4 in one course is shown. Steps 1 to 4 are knitted in the same manner as in the first embodiment.

In order to continue the stitches of the small loop knitted fabric portion 4 knitted in Steps 3 and 4, the rear knitted fabric is knitted one course using only the yarn 3 (step 5), and then the front knitted fabric is knitted one course (step 6). ) The small loop knitted fabric portion 4 is further formed. The knitting at this time alternately forms a knit loop and a tuck loop. At this time, knitting is knitted with a stitch density of 35.

The same knitting as in Step 5 and Step 6 is performed twice (Steps 7 to 10). The tuck loop is formed in the same wale in each step.

In steps 9 and 10, the rear knitted fabric is knitted one course by using only the fine yarn 3 (step 11), and then the front knitted fabric is knitted one course (step 11) so as to continue the stitch of the small loop knitted fabric portion 4 that is knitted (step 11). 12) A final course part 5 is formed. The stitch of the final course portion 5 is knitted with a stitch density of 75 to form a large loop.

In the present embodiment, the jaw loop is in a state where four superfine yarns overlap, so that the opening area is very small. As a result, the stitches of the final course part 5 are formed continuously in the tuck loop of four superfine yarns superimposed, so that the large loop of this final course part 5 is formed by the tuck loop or knit loop of the small loop knitted fabric part 4 on the sinker loop side. It is in a tightened state. In particular, large loops formed continuously in the tuck loop become more difficult to fall out of the small loop. As a result, the opening end formed in the small loop knitted fabric portion 4 and the final course portion 5 becomes very difficult to loosen.

The cylindrical knitted fabric having an opening at the end of the knitting of the present invention is knitted to a value smaller than the stitch density when knitting the main body of the knitted fabric by plating, forming a small loop knitted fabric portion. Since it becomes the structure which forms the big loop which becomes a final course part in a loop, the big loop formed continuously in the loop of which the loop area of the small loop knitted fabric part is small becomes difficult to fall out. As a result, even if an inexpensive and elastic yarn such as TFT is used, the touch is good and a good anti-loosening effect is obtained.

Particularly, if the small loop knitted fabric portion is formed by the knit loop in one course, and the final course portion is formed, the small loop is formed in the double loop formed by the scanning and the fine yarn, so that the opening area of the small loop is small loop. Subsequently, the opening area can be made smaller than the loop in which the small loop is formed. Therefore, a large loop can make it difficult to loosen because the resistance increases with respect to the small loop in one course knitting.

In the case where the small loop knitted fabric portion is formed by knitting a plurality of courses, by forming a tuck loop, in the tuck loop, a plurality of fine yarns can be overlapped, so that the opening area of the tuck loop can be made as small as possible. If a large loop to be the final course portion is formed in this tuck loop, this large loop becomes difficult to fall out of the small tuck loop of the opening area, so that a good anti-loosening effect is obtained.

According to the knitting method of a cylindrical knitted fabric having an opening at the end of the knitting according to the present invention, the yarn is used only for the anti-loosening treatment because the anti-loosening treatment is performed by using the fine yarn when plating the knitting. There is no need to install a feeder to separate. As a result, it is possible to use the feed yarn having been conventionally used for the anti-loosening treatment for other purposes, or to reduce the number of yarn feed holes.

According to the cylindrical knitted fabric provided with the opening part at the end of the knitting of this invention and the knitting method, since the yarn for anti-loosening treatment is added as a fine yarn, the elastic thread (for example, FTF) generally used conventionally can be used. The manufacturing cost is also lower than that of the case of using a toilet or special thread.

In particular, the tubular knitted fabric of the present invention is preferable for the end treatment of insertion holes such as socks and gloves.

The cylindrical knitted fabric of the present invention and its knitting method are suitable for knitting socks or gloves knitted in a non-sewing machine using a flat knitting machine.
