Description

  The present invention relates to a seamless tubular knitted fabric provided with a pile knitted fabric knitted using a seamless stocking circular knitting machine, and a knitting method thereof.

  Conventionally, seamless tubular knitted fabrics such as pantyhose, stockings and arm covers are knitted by a seamless stocking circular knitting machine having a small cylinder diameter of 4 inches to 5 inches. This seamless stocking circular knitting machine has a small knitting stitch in addition to a small cylinder diameter, and a pile sinker for providing a pile loop is required to be more precise than a circular knitting machine with a large cylinder diameter. It was difficult to provide. Therefore, there is no long model of seamless stocking circular knitting machines equipped with pile sinkers. Recently, Lonati has finally manufactured and manufactured seamless stocking circular knitting machines exclusively for pile weaving with cylinder diameters of 5 inches and 4-1 / 2 inches. They have just been sold (see Non-Patent Document 1).

  Therefore, as far as the inventor knows, pantyhose and stockings knitted by a seamless circular knitting machine with a cylinder diameter of 4 inches, a seamless circular knitting machine that is not dedicated to pile knitting, even if it is 4-1 / 2 inch or 5 inches There is no genuine pile knitted fabric in the past, and instead, a so-called pile-like knitted fabric with a pile-like loop formed on the back surface by knitting such as knit, tuck, tuck, tuck, knit (patent document) 1), or a pile-like loop formed by tacking this pile-like knitted fabric was cut with a file or the like to be raised, which was commercially available. Patent Document 2 also discloses a float in which knitting yarn is floated on the back surface by knitting, knit, miss, miss, miss, knit on the course of wooly nylon while alternately knitting covering yarn and wooly nylon one by one. Pile knitted fabric has been proposed.

  However, the pile-like knitted fabric and the float pile knitted fabric of Patent Document 1 are formed with yarns constituting the ground structure as a tuck structure or float structure as an alternative to raising, so that if the tack breaks, pilling or wire The problem is that it is easy to occur and is inferior in durability, and when worn, the tack part extends sideways and the pile-like loop breaks down, so the problem is that the touch is inferior compared to a true pile knitted fabric. There was a problem that the portion was vertically striped and inferior in design. In addition, when the pile-like loop is cut with a file or the like, there is a problem that the thread comes off immediately after washing and becomes unusable. And, since there is no one that has a pile sinker yet in a circular knitting machine for a seamless stocking with a cylinder diameter of 4 inches and a seamless circular knitting machine having a needle selection mechanism even with 4-1 / 2 inches or 5 inches, These problems still exist in seamless tubular knitted fabrics knitted by such circular knitting machines.

The present invention is not limited to the following embodiment.

(First embodiment)
FIG. 1 shows a pile knitted fabric 11 of a seamless tubular knitted fabric according to a first embodiment of the present invention. The pile knitted fabric 11 is a pearl knitting course 14 in which all the knitting courses (C1 to C9 in FIG. 1) are pile knitted with a front yarn 12 and a back yarn 13 attached thereto. The front yarn 12 has a flat knitting structure, and the back yarn 13 has a pile knitting structure in which the back yarn 13 of the flat knitting sinker loop portion is pulled out to form a pile loop 13a. A nylon yarn of 10 to 80 denier single covering yarn or double covering yarn is used for the front yarn, and a polyester yarn of 10 denier to 80 denier is used for the back yarn. As the back yarn, cotton yarn, exothermic nylon yarn, exothermic cotton yarn, and absorption / release nylon yarn can be used.

  Here, the knitting method of the pile knitted fabric 11 is demonstrated using FIG. The pile sinker 108 slides in the direction of the arrow shown in FIG. 5A (the radial direction of the cylinder 101). In FIG. 5A, the pile sinker 108 moves forward most (slides to the right in FIG. 5). The pile loop 13a formed by the back yarn 13 is supported by the pile nose 108a of the pile sinker 108.

  From this state, as shown in FIG. 5B, the pile sinker 108 moves backward (slids to the left in FIG. 5), and the previously formed pile loop 13a is detached from the pile nose 108a. At the same time, the cylinder needle 102 rises to the highest position and catches both the front yarn 12 and the back yarn 13.

  Then, as shown in FIG. 5C, the pile sinker 108 advances the back yarn 13 and the front yarn 12 up and down the pile nose 108a, and the cylinder needle 102 starts to descend in this state. Then, as shown in FIG. 5D, the back yarn 13 is hooked on the pile nose 108a, and the front yarn 12 is hooked on the lower nose 108b to form the pile loop 13a and the sinker loop 12a.

(Second Embodiment)
FIG. 2 shows a pile knitted fabric 21 of a seamless tubular knitted fabric 20 according to a second embodiment of the present invention. The pile knitted fabric 21 is a pile knitted course 24 having a pile loop 23a (in FIG. 2, C1 , C3, C5,..., C11) and a valley course 25 (in FIG. 2, C2, C4, C6,..., C10) that does not have a pile loop 23a sandwiched between adjacent pile knitting courses 24, 24. Have. FIG. 3 shows a pantyhose 200 obtained by cutting and sewing a pair of seamless tubular knitted fabrics 20 and 20. The pantyhose 200 includes a pattern 28 formed by gathering knitting portions 27 with a pattern yarn, which will be described later.

  The pile knitting course 24 is knitted by simultaneously feeding two of the front yarn 22 and the back yarn 23 to the knitting openings 103a and 103c (both not shown in the drawing) of the circular knitting machine 100, which is the first embodiment. In the same manner as above, a pile loop 23a is formed.

  The valley course 25 is knitted into a flat knitting as shown in FIG. 2 by feeding the front yarn 22 to the knitting openings 103b and 103d of the circular knitting machine 100. The valley course 25 has a patterned yarn-attached knitting portion 27 in which the patterned yarn 26 is partially knitted with a cut boss. As described above, the seamless tubular knitted fabric of the second embodiment is such that the protruding portion and the cut end of the patterned yarn-attached knitted portion 27 are pile loops because the patterned yarn-attached knitted portion 27 is sandwiched between the pile knitting courses 24. Since it is lost in the bulge of 23a, the deterioration of the touch by the knitting part 27 with a patterned thread can be suppressed.

(Third embodiment)
FIG. 4 shows a pile knitted fabric 31 of a seamless tubular knitted fabric according to the third embodiment of the present invention.
Similar to the pile knitted fabric 21 of the second embodiment, the pile knitted fabric 31 includes a pile knitted course 34 (in FIG. 4, C1, C3, C5,..., C11) and a valley course 35 (in FIG. 4, C2, C4, C6,..., C10) are alternately knitted, and the valley course 35 is provided with a knitted portion 37 with handle yarn (including those represented by 37a and 37b).

  Unlike the second embodiment, the pattern yarn-attached knitting portion 37 of the pile knitted fabric 31 according to the third embodiment is not cut at both ends. For example, the pattern yarn 36 fed to the knitting opening 103 is used by the pattern yarn 36. Among the plurality of knitted portions 37 with knitted pattern yarns, the adjacent knitted portions 37 with knitted yarns are connected by crossover yarns 39 at the ends facing the circumferential direction of the seamless tubular knitted fabric. As described above, the patterned yarn-attached knitting portion 37 of the pile knitted fabric 31 can further suppress the deterioration of the touch due to the provision of the patterned yarn-attached knitting portion 37 because the patterned yarn 36 does not have a cut end.

  Here, the knitting method for connecting the pattern yarn-attached knitting portions 37 with the cross yarns 39 will be described with reference to FIGS. 4 and 6. FIG. 6 shows how the valley course 35 is knitted by the knitting opening 103b. Further, in FIG. 4, the knitted portion 37a with the pattern yarn of the C2 course and the knitted portion 37b with the pattern yarn of the C6 course show the adjacent knitted portions with the patterned yarn fed and knitted from the knitting opening 103b. Hits the front side of the knitting direction knitted first, and 37b hits the rear side of the knitting direction knitted later.

  First, when the knitting of the knitting portion 37a with the handle yarn on the front side in the knitting direction is finished, the yarn feeder 105a at the tip of the yarn finger 105 is lifted as shown in FIG. Operate as follows. At the same time, the circular cutter 107 rises to the cutting avoidance position (position shown in FIG. 6A) and holds the handle yarn 36 so as not to cut it.

  When the cylinder 101 is rotated halfway with the handle yarn 36 held so as not to be cut, as shown in FIG. 6A, the rear end 37c of the handle yarn 36 in the knitted portion 37a with the handle yarn becomes the knitting point 103b. Since it moves to the opposite knitting opening 103 d side, the pattern yarn 36 (crossover yarn 39) is in a state of crossing the inside of the cylinder 101. A tension is applied to the handle yarn 36 so that the handle yarn 36 is returned to the upstream side of the yarn supply by the tension adjusting device 106. Further, the cylinder 101 is rotated halfway so that the rear end 32b of the knitted portion with the handle yarn is at the knitting opening 103b. When returning to the side and the tension of the handle yarn 36 is loosened, the handle yarn 36 (crossover yarn 39) crossing the cylinder 101 is unreeled as shown by the phantom line in FIG. The part that has been pulled is pulled back to the upstream side by the register mark 106a.

Then, when the part where the knitting of the patterned yarn-attached knitting portion 37b is to be started reaches the knitting port 103b (yarn supplying port 105a), the yarn supplying port 105a is lowered and the knitting of the rear patterned yarn-added knitting portion 37b is performed. . In this way, the pattern yarn 36 is knitted so that the rear end 37 c of the pattern yarn-attached knitting portion 37 a and the front end 37 d of the pattern yarn-added knitting portion 37 b are continuous with the transition yarn 39.
In the example of FIG. 4, the pattern yarn-attached knitting portion 37 is also provided in the C4, C8,... Course knitted by being fed from the knitting opening 103d.

  The present invention is not limited to the above-described form. For example, different types of pattern yarns may be supplied to the knitting port 105b and the knitting port 105d. Seamless tubular knitted fabrics include not only pantyhose but also short stockings, arm covers, and other seamless seamless tubular knitted fabrics. A known knitting structure such as the structure by can be added as appropriate.

  The knitting method of the seamless tubular knitted fabric of the present invention is not limited to the circular knitting machine 100 shown in FIG. 6, and the seamless tube provided with the pile knitted fabric of the present invention is within the scope of the present invention. As long as the knitted fabric can be knitted, a circular knitting machine having a different structure can be used.
