Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel georgette-like knitted fabric made by applying bound spun yarn having a homogeneous structure.

Conventionally, georgette fabrics are made by strongly twisting filaments or spun yarn into S or 2 using a twisting machine, and then twisting the S twist and Z twist.
Twist the twisted yarn in the vertical or horizontal direction of the fabric,
It is manufactured by appropriately arranging it horizontally.

FIG. 1 is an enlarged view of an example of such a conventional georgette fabric, where W indicates warp threads and F indicates weft threads.

In this way, the georgette fabric has S twist yarns 4 and 23.
It is constructed by arranging 9 strongly twisted yarns 4' alternately vertically and horizontally, and the graining is performed by the torque of the highly twisted yarns.

However, conventional georgette fabrics have the disadvantage that the constituent yarns are extremely thin due to their strong twist, and the fabric has little luster.

In addition, the manufacturing process requires strong twisting in reverse twists such as S twist and 2 twist, which requires manpower and time.

The object of the present invention is to provide a novel knitted fabric having a glossy, easy-to-manufacture georgette-like texture without the drawbacks of georgette fabrics.

The georgette-like knitted fabric of the present invention that achieves this object is a knitted fabric whose main component is a bound spun yarn composed of finite-length fibers, and the knitted fabric has a substantially twist-free core fiber. A bound spun yarn in which the bundle is spirally wound in the Z direction with finite length fibers and a bound spun yarn in which the bundle is spirally wound in the S direction are appropriately arranged adjacent to each other vertically and/or horizontally. The georgette-like knitted fabric is characterized in that the bound spun yarn has an uneven shape along the length direction.

In the present invention, a finite length fiber refers to a stable fiber.

Further, the stable fiber length may be any fiber length within a range that allows spinning.

Hereinafter, the present invention will be described in detail according to embodiments shown in the drawings.

FIG. 2 is an enlarged view illustrating an example of a bound spun yarn used in the present invention.

In this invention, as shown in FIG. 2, a bundled spun yarn in which finite length fibers 2 are uniformly wound spirally in the S or Z direction around a substantially twist-free core fiber bundle 1 is used. and
The core fiber bundle 1 of the yarn has no twist, that is, the single fibers are arranged substantially parallel to each other in the yarn axis direction, so it has very good luster.

Furthermore, tied spun yarns with such a structure have unevenness on the yarn itself due to its structure, and if the manufacturing conditions are changed to make a yarn that emphasizes these unevenness, it can be made into a highly twisted yarn without twisting. It can have a similar appearance, feel, and crispness, and has the characteristic that the yarn does not weaken due to strong twisting.

Therefore, the georgette-like knitted fabric of the present invention, which is a combination of bundled spun yarns with the wrapped fibers 2 in the S direction and those in the Z direction, as shown in FIG. 2, uses highly twisted yarns. Although it has a similar texture, it is very glossy.

An example of the georgette-like fabric of this invention is shown in FIG.

Here, 3 is a bundled spun yarn in which the wrapped fibers are in the S direction;
' are bound spun yarns in the Z direction, which are arranged vertically and horizontally.

Although W indicates a warp thread and F indicates a weft thread, the present invention is not limited to this embodiment, and may be arranged only in the warp or weft, and the structure may be changed as appropriate.

The bound spun yarn used in this invention is, for example, JP-A No. 50-1
It can be manufactured using a spinning machine that combines a temporary twisting nozzle and a 70-ring apron as shown in Japanese Patent No. 23954.

When this method is used, by increasing the overfeed ratio between the front roller and the take-up roller, the yarn shape can be made into a strong twist and can have a large torque.

In addition, the winding direction of the wrapped fibers can be determined by simply changing the heating direction of the temporary twisted nozzle, that is, by replacing the nozzle with a reverse twisted nozzle (manufacturing is very easy).

It should be noted that the bound spun yarn used in the present invention does not need to be entirely composed of stable components, and the twist-free core fiber bundle in FIG. 2 may contain filaments.

Furthermore, the present invention can also be applied to knitted fabrics such as vertical knitting and circular knitting.

In this case as well, if the S-direction binding yarn and the Z-direction binding yarn are appropriately arranged adjacent to each other in the same manner as in the above-mentioned woven fabric, a georgette-like knitted fabric having good luster and crispness can be obtained.

In such a case, in the case of circular knitting (horizontal knitting), the knitted fabric of the present invention having a balanced structure without diagonal crossing can be obtained by alternately feeding the S-direction bound spun yarn and the Z-direction bound spun yarn in the weft yarn supply. can get.

In the case of warp knitting, by alternately arranging S-direction bound spun yarns and two-direction bound spun yarns as warp warp yarns, the knitted fabric of the present invention with a balanced structure without diagonal crossing can be obtained.

Therefore, the structure of the present invention can be applied only in the horizontal direction in normal weft knitting, and only in the vertical direction in vertical knitting. However, in knitting that uses warp and weft yarns such as the weft thread insertion method (weft lock method), The structure of the present invention can be applied to at least one of the yarn and the weft.

As mentioned above, although the georgette-like knitted fabric of the present invention has a similar texture to conventional georgette fabrics using strong twist yarns, it has excellent luster and also The yarn is extremely thin and thin (it has the excellent effect of being easy to manufacture).

Example 1 Using a binding spinning device having a yarn forming section consisting of a feeding device with two upper and lower aprons and an air false twisting nozzle as shown in FIG. 1 of JP-A-50-123954, the following procedure was carried out. A bundled spun yarn was spun under these conditions.

■ Raw materials used: Polyester fiber cut sliver 1.5 denier, 130 mmV ■ Draft method: 3-wire prong method % type ■ Overfeed rate: 9% ■ Nozzle pressure air: 3.0 kg/crrt ■ Spinning count: Nm80 False twisting nozzle is S Using two types of twisted and Z twisted yarns, two types of bundled spun yarns were obtained in which the wrapping directions of the bundled fibers were in the Z direction and the S direction.

The bound spun yarn had an uneven appearance due to dripping in the length direction, and had a crunchy taste.

Next, a plain woven fabric was produced by arranging the bundled spun yarns vertically and horizontally so as to alternately adjoin S and Z, and a woven fabric as shown in FIG. 3 was obtained.

That is, the surface had grain-like unevenness, was rich in variation, had a good glossy quality, and was a georgette-like fabric with a crisp taste.

Comparative Example 1 In Example 1, a similar woven fabric was prototyped using only the bound spun yarn having wrapped fibers in the Z direction when forming a plain woven fabric, but a georgette-like fabric could not be obtained.

That is, although the gloss and crispness were the same, there was no surface change and only a plain fabric could be obtained.

Similarly, only a bound spun yarn having S-direction twisted fibers was used to produce a woven fabric, but similarly only a plain fabric could be obtained.

Example 2 In Example 1, when manufacturing the bundled spun yarn, a multifilament yarn (50 denier, 24
filament) was inserted to obtain a bound spun yarn.

When a woven fabric was made using this bound spun yarn in the same manner as in Example 1, the surface had grain-like unevenness and was rich in variation.
The result is a georgette-like fabric that is glossy and of good quality, with crispness, elasticity, and tension.
