Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention provides a binding spun yarn that has an excellent crisp feel, a good texture and a thin feel, and is suitable for spring/summer knitted fabrics without the irritation peculiar to ring yarns. Regarding knitted fabric using.

<Relationship with Prior Art> Conventionally, ring yarns made of cotton fibers have been used as knit yarns in knitted fabrics. However, (1) the flat fabric has an excellent soft texture and voluminous feel, making it suitable for fall/winter materials or underwear; however, (1) it lacks a crisp feel and S/I bulges, making it unsuitable for spring/summer knitted fabrics. Met. Therefore, ring yarns made of hemp fibers have often been used in spring/summer knitted fabrics.

However, such knitted fabrics always have a poor texture. Furthermore, since the 1-ring yarn has a structure in which the entire system is actually twisted, the knitted fabric inevitably lacks a thin feel. Further, the knitted fabric using the one-ring yarn had an irritation peculiar to the one-ring yarn, which was not desirable in terms of quality.

<Object of the Invention> The present invention (1) improves the unsuitability of the conventional knitted fabrics as knitted fabrics for spring and summer, and creates a knitted fabric using bound spun yarn suitable for knitted fabrics for spring and summer, which has unprecedented advantages. The purpose is to provide land.

<Configuration of the Invention> The present invention has the following configuration to achieve the above object. In other words, the present invention is a bundled spun yarn consisting of a fiber bundle of one core and a bundled fiber that bundles the Mli fibers of the core. This is a knitted fabric in which the bound spun yarn has an uneven shape in the yarn axis direction, and the thickness of the bound spun yarn is in the range of English cotton count 40 to 100, and one cotton fiber is This is a knitted fabric using bound spun yarn, characterized in that the bound spun yarn contains as a constituent fiber of the bound spun yarn.

The present invention will be explained in detail below. First, the bound spun yarn used in the knitted fabric of the present invention consists of one core fiber bundle and binding fibers that bundle the one core fiber bundle. For example, by drafting roving, one or two It is produced by passing it through a fluid false twisting nozzle to form a yarn. The bound spun yarn does not cause irritation when used in knitted fabrics because the 1-ring yarn and the loose 1-bound fibers are wound around its surface at relatively intervals. 1. This phenomenon cannot be resolved with ring threads. Therefore, it can be said that this is the reason why bound spun yarn is used in the present invention.

Next, one bundled spun yarn must have an uneven shape in the yarn axis direction. This is to give a sense of brilliance.

This uneven shape is created by drafting one roving or sliver.
It is determined by how positive the surface speed of the front solar is relative to the surface speed of the draw-out roller when supplying the fluid in the order from the roller to the draw-out roller, but usually 6 to 9%. Overfeed rate is preferred. If it is less than 6%, the fiber bundle will be stretched and difficult to spin, and it will be difficult to form an uneven shape. On the other hand, if it exceeds 9%, the uneven shape will be noticeable and it will be difficult to knit. Furthermore, the thickness of the bundled spun yarn must be in the range of 40 to 100 Eiwa cotton count. Generally, since the fiber bundles of one core of a bound spun yarn are relatively parallel, there is relatively little cohesiveness between the individual fibers, giving the yarn a thin feel. However, there is a limit to this, and when the yarn count is less than 140, the effect of the thickness of the yarn is more than overcome, and the thin feel is lost.On the other hand, when the yarn count exceeds 1100, the soft texture increases, but the crispness becomes poor. .

Furthermore, the constituent fibers of the bound spun yarn are also an important requirement, and at least one cotton fiber must be included.

In order to make a knitted fabric for spring and summer use, it must have both a crisp feel and a good texture, and for this purpose, cotton fibers are used to give it a nice texture. The blend ratio of cotton fibers contained in the bound spun yarn is 20 to 10% of the bound spun yarn.
Preferably it is 0% by weight. When 20% by weight is not added, the soft texture tends to be lost even though the texture is crisp. When the weight is 100 layers, the material has a very soft texture. It should be noted that, except when 100% by weight of cotton fibers are included, in other cases, it is preferable that the remaining staple fibers be mainly composed of polyester fibers. However, it is preferable to include some low melting point fiber, for example less than 3% by weight, in order to further enhance the crunchiness. Low melting point fibers have a lower melting point than any of the main constituent fibers.
Examples include polyethylene-polyamide fibers. The other short fibers to be mixed with the cotton fibers are preferably those having an average fiber length similar to that of the cotton fibers, for example, 50 or less. This is to avoid deteriorating the feel of the cotton fibers. Note that since the knitted fabric must be thin for spring and summer wear, it is preferable to use jersey jersey for outerwear and milling knit for underwear. Also, the weight of one knitted fabric is 100~
Go.

f/d is preferred.

<Effects of the Invention> As described above, according to the present invention, knitting using bound spun yarn suitable for spring/summer knitted fabrics, which has an excellent smooth feel, good texture, and a thin feeling, and does not have the irritation characteristic of one-ring yarns. The effect of gaining ground is produced.

Example Polyester fiber staple 1aItA (38-equal length cut, 1.ga) and cotton fiber in weight percent 65 = 35
36' on a binding spinning machine with one fluid false twisting nozzle! 1 (English cotton count) was spun. The spinning conditions are as follows.

Wrapping direction of binding fibers: 2 directions.

The one-fluid plate twisting nozzle used was one shown in Japanese Patent Publication No. 58-9170. Next, milling knitted fabric (basis weight: l 50 t/wl) is made using this bound spun yarn.
) When the texture of this milled knitted fabric was examined, it was found to have a very crisp feel and a soft texture that tends to feel thin. For comparison, a 36'-day ring yarn was produced under the same conditions and a milled fabric was knitted under the same conditions; however, the milled fabric had a lot of irritation and lacked crispness.
