Abstract

PURPOSE:To uniformly form short and dense suede-tone fluffs by forming a balloon of twisted yarn while untwisting the yarn through a false-twisting hollow spindle and contacting the balloon with the inner face of a ring-shaped abrasive wheel. CONSTITUTION:Twisted yarn 2 composed of plural yarns is drawn from a cheese 1 and guided through a delivery roller 3 to a false-twisting hollow spindle 4 rotating in the untwisting direction to effect the untwisting of the yarn. A balloon A of the yarn 2 is formed between a flier 5 attached to the spindle 4 and a guide 8 placed above the flier. At the same time, the untwisted yarn 6 forming the balloon A is made to contact with the inner face of a ring-shaped abrasive wheel 7 to form fluffs on the whole circumference of the yarn 6. The treated yarn is passed through a feed roller 10 and wound in the form of a cheese 11. The ring-shaped abrasive wheel 7 may be replaced with a ring-shaped horizontal friction material contacting its outer circumference with the balloon A.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for processing a raised yarn for providing fluff on the yarn.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3, a raised yarn is processed by bringing the yarn 12 into contact with the outer circumference of a rotating friction member, that is, an annular grindstone 13 to give fluff 12a. The clothing 1 provided on the outer circumference of the cylinder 14 that rotates the thread 12.
5 is applied to give the fluff 12a, or, as shown in FIG. 5, the yarn 12 is brought into contact with the inner surface of the rotating circular grindstone 16 to give the fluff 12a.

[0003]

As shown in FIG. 6, the fluff 12a has a raised yarn 1 obtained by the conventional processing method.
Only on the outer side of No. 7, it was formed relatively coarsely and for a long time, and lacked a fluffy feeling as a whole.

An object of the present invention is to provide a method for processing a raised yarn in which fluff with a short suede-like density and high density is uniformly applied to the yarn, and an apparatus therefor.

[0005]

According to the method of the present invention, a plurality of twisted yarns are untwisted by a flyer attached to a false twist hollow spindle to form a balloon, and the balloon is formed into an annular friction body. It is characterized by generating fluff by contacting the inner surface of the.

The device according to the invention comprises a guide provided above the false twist hollow spindle axis and a thread which is attached to the false twist hollow spindle and extends radially outwardly in cooperation with the guide to untwist the yarn. A flyer that swirls to generate a balloon and a horizontal annular friction body that circumscribes the balloon are provided.

[0007]

In the present invention, the plurality of untwisted yarns forming the balloon are brought into contact with the inner surface of the annular friction body, so that each of the yarns individually comes into contact with the friction body. Brushed around the circumference. Therefore, the raised yarn that has been twisted again into the original state is raised not only on the outside of the yarn but also on the inside as a whole, and a raised yarn with a uniform suede length and dense fluff is obtained.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, a feeding roller 3, a false twisting hollow spindle 4, an annular friction body, that is, an annular grindstone 7, a guide 8 and a feeding roller 10 are arranged above the cheese 1 in this order from the bottom. A rolled cheese 11 is provided above the feed roller 10. And
A flyer 5 is provided on the upper portion of the false twist hollow spindle 4 and extends outward in the radial direction.

Next, the manner of raising hair will be described.

Twisted raised yarn 2 from cheese 1.
Is untwisted through the inner hole of the false twisting hollow spindle 4 which rotates in the untwisting direction via the delivery roller 3, and is guided to the flyer 5, and the flyer 5 forms a balloon A with the guide 8. Each of the untwisted yarns 6 forming the balloon A individually comes into contact with the inner surface of the annular grindstone 7,
The entire circumference of the thread 6 is preferably raised. These yarns 6 are twisted and returned to the original state, and wound on the winding cheese 11 via the feed roller 10. However, due to the above action, only the outside of the napped yarns 9 as shown in FIG. Not only the fluff 9a, but also the fluff 9b on the inner side, the fluff 9 as a whole
A suede-like raised yarn 9 in which a and 9b are uniform and dense is obtained. At this time, as compared with the conventional method of rotating the grindstones 13 and 16, it is easier to keep the tension of the thread 6 uniform by the rotation of the flyer 5, that is, the spindle 4, and the vertical movement of the annular grindstone 7 and the rotation of the spindle 4 are performed. The degree of contact of the yarn 6 with the annular grindstone 7 is subtly changed by the change, and the raised yarn 9 with less unevenness of raising is obtained.

[0012]

As described above, according to the present invention, the balloon is formed by the flyer while untwisting the twisted yarn by the false twist hollow spindle, and the balloon is brought into contact with the inner surface of the annular grindstone at a right angle to shorten the suede tone. It is possible to produce a raised yarn in which fluff having a high density is uniformly applied with high productivity.
