Description

[Detailed description of the invention]

Pile knitted fabrics in a circular knitting machine are usually produced by a single sinker pile knitting machine, but they can also be produced by a double circular knitting machine using Bows needles or hook needles. Nowadays, the most sought-after method by those involved in knitting is the possibility of producing pile knitted fabrics using commonly used double circular knitting machines, rather than special machines such as sinker pile circular knitting machines. Therefore, the method of manufacturing pile knitted fabrics using bows needles and hook needles is a method that satisfies those involved in knitting, but it cannot produce pile knitted fabrics as uniform and problem-free as a dedicated machine. Therefore, the object of the present invention is to knit a pile knitted fabric without using any auxiliary equipment using a commonly used double circular knitting machine that is not a dedicated pile machine. The present invention will be explained in detail. The pile knitted fabric according to the present invention is based on a one-complete structure with three yarn feeders. That is, at the first yarn feeder, the cylinder needle is knitted and the dial needle is tacked (Figure 1-1), and at the second yarn feeder, only the dial needle is knitted (Figure 1-2).
Knit only the cylinder needle at the third yarn feeder (Figure 1-3). In addition, in FIG. 1, the knitted fabric that can be knitted is exactly the same even if the warp is alternated between the dial side and the cylinder side. Now, at this time, if the loop length formed at the third yarn feeder is made larger than the loop length of the other two yarn feeders, the yarn of the jersey texture at the third yarn feeder will form a spiral pile (Figure 2-1). form and protrude from the surface of the knitted fabric. This will be explained more specifically. Now, FIG. 4 shows an actual diagram of the organization shown in FIG. 1. These relationships are as follows: 1, 2, 3 in Figure 1 are 1, 2, 3 in Figure 4,
Corresponds to 3. This body diagram shows a normal organization, and no spiral piles occur. FIG. 5 shows an actual diagram in which the yarn of the third yarn feeder is removed from this actual diagram (FIG. 4). According to this, the jersey knitted fabric (Fig. 5-2) knitted by the second yarn feeder (Fig. 1-2) of the basic structure (Fig. 1) is the basis.
It can be seen that the knit tack structure (FIG. 5-1) knitted by the first yarn feeder (FIG. 1-1) is connected by the tuck portion T. Because of this structure, the knit tack organization (Fig. 5
-1) The knit part K is in a state where it is extremely easy to move freely. In this way, the tuck part T
The knit part K, which has become extremely easy to move by tying it with
When knitting with the jersey weave in 3), if the loop length L3 of this jersey weave is determined to be within a certain range, the knit portion K of the first yarn feeder (Figure 1-1),
The cotton sheeting structure at the third yarn feeder (Figure 1-3) allows free movement with respect to each other without constraining each other. As a result, the jersey texture at the third yarn feeder changes into a spiral shape, which is different from the inherent properties of the jersey texture. This is shown in FIG. In order to form a spiral pile in this way, it is necessary to adjust the loop length L1 (not including the tuck part) and the ratio of L2 and L3 of each of the first yarn feeder, second yarn feeder, and third yarn feeder of this structure. It becomes important. To put this relationship into perspective, a spiral pile is formed by knitting so that the loop length L3 formed at the third yarn feeder is larger than the loop lengths at the other two yarn feeders. If further limited, the loop length L3 knitted at the third yarn feeder
When is set to 1, the loop length L1 of the first yarn feeder is 0.7
≦L1≦0.9, loop length L2 of the second yarn feeder is 0.8≦L2
<1, the jersey texture at the third yarn feeder changes to a spiral pile. The ratios of the loop lengths L1, L2, and L3 have been derived from numerous examples. Regardless of the gauge of the knitting machine used, the thickness of the yarn used, etc., if the ratios are selected within this range and knitting is performed, A good spiral pile knitted fabric can be obtained. Here, Tables 1 and 2 show typical examples from among those examples. In other words, Table 1
In this paper, the total loop length of 100 wales of pile knitted fabric was actually measured and presented. The respective average values are 31.0 cm for the first yarn feeder, 34.0 cm for the second yarn feeder, and 34.7 cm for the third yarn feeder. Looking at this ratio, when the third yarn feeder is set to 1, L1:L2:L3=0.89:
0.98:1.00. For the yarns shown in Table 1, this ratio is the best ratio for generating spiral piles. Also, when looking at the ratio in Table 2, L1:L2:L3=0.74:0.81:1.00, and piles occur most often with this ratio. By knitting within the above conditions, a pile knitted fabric having a spiral pile, which has not conventionally existed in this field, can be obtained, as shown in detail in FIG. This is a new pile knitted fabric that looks as if spiral springs are laid parallel to the surface of the knitted fabric (Figure 2), and is in no way inferior to conventional pile knitted fabrics. Also, if knitting is carried out by supplying yarn to the first yarn feeder that is thinner, has a lower coefficient of friction, and has better slippage than the other two yarn feeders (for example, a synthetic fiber green yarn...a yarn that has not been processed in any way). , spiral piles may appear even more prominently. Furthermore, if the yarn fed to the third yarn feeder is a yarn with high rigidity (for example, synthetic fiber raw yarn), the angle of the spiral pile (Figure 2-2) will not be constant, resulting in random spiral piles (Figure 3). A knitted fabric is obtained, and the knitted fabric has even higher fleece properties. In addition, if a yarn with rotational torque in a certain direction (e.g., spun yarn, false twisted yarn) is fed to the third yarn feeder, the spiral pile will be more uniform and the angle of the spiral pile (Figure 2-2) will be constant. A knitted fabric is obtained. Furthermore, if a hygroscopic yarn is used at the second yarn feeder, the part that comes into contact with the skin will be hygroscopic, and a knitted fabric with a pile surface will be obtained, improving the feel of the garment. Note that it is easily possible to incorporate any other organization into the basic organization described above. As described above, the spiral pile knitted fabric according to the present invention can be knitted using a conventionally used circular knitting machine without any auxiliary equipment and can be knitted into a splendid pile knitted fabric, which is a great benefit to those involved. The profits are huge.
