本発明は扁平糸の染色法に関するものである。
従来、綛の状態でしか染色し得なかつた扁平糸を
コーン又はチーズ（以下単にチーズと称す）の状

を提供するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for dyeing flat threads.
To provide a method for dyeing flat yarn, which conventionally could only be dyed in a skein state, in a corn or cheese (hereinafter simply referred to as cheese) state while retaining the characteristics of the flat yarn.

なわれず染斑を生ずる。 As shown in Figures 1, 2, and 3, flat yarn refers to one in which the width a of the cross section with respect to the fiber axis is several times to several thousand times the thickness b, but flat yarn has a unique characteristic due to its flat shape. Because it has luster and waist, it can be used in clothing, hats,
It is also widely used in other miscellaneous goods. Conventionally, flat yarns have been dyed in a skein-like manner using a skein dyeing machine such as a jet dyeing machine or a rotary bag so that the characteristics of the flat yarns are not lost during dyeing. If flat yarn wound into a cheese shape can be dyed using a cheese dyeing machine, processes such as skein winding and rewinding onto the bobbin after dyeing can be omitted, and dyed yarn that does not lose the characteristics of flat yarn can be obtained. However, it is extremely difficult to wrap the flat thread into cheese so that it can be dyed. In other words, when winding a flat yarn around a dyeing tube with holes, if you wind it so that it forms a soft yarn layer that allows the dye solution to pass through, the flat yarn tends to cause the yarn layer to collapse, making winding itself difficult. Even if the yarn can be wound, the yarn layer may collapse during dyeing, or the winding density (yarn weight in g/cm 3 ) may vary locally, resulting in dyeing spots. If the yarn is tightly wound, it is possible to prevent the yarn layer from collapsing, but the dye solution cannot pass through the yarn layer, and uniform dyeing is not achieved, resulting in uneven staining.
本発明者らは、扁平糸のチーズ染色を完成する
目的をもつて鋭意研究をかさね、扁平糸に適当な
撚数の自撚を与えた後、多孔を有する染色用ボビ
ンに巻くことによつて、チーズ染色が可能となる
ことを見出し、本発明をなすに至つた。 The inventors of the present invention have carried out extensive research with the aim of perfecting the cheese dyeing of flat yarns, and after giving the flat yarns an appropriate number of self-twists, winding them around a perforated dyeing bobbin. They discovered that it is possible to dye cheese, leading to the present invention.
即ち、本発明は、繊維軸に対する横断面の幅ａ

関するものである。 That is, in the present invention, the width a of the cross section with respect to the fiber axis
When dyeing flat yarn whose width a is 0.1 mm to 2 mm and whose width a is 5 times or more the thickness b, the flat yarn is twisted in advance with a number of twists within the range shown by the following formula, and then The present invention relates to a method for dyeing flat yarn, which is characterized in that the yarn is dyed after being wound into a cheese or cone shape around a tube.
但し、 ａ：扁平糸の幅ａの長さ（ｍ）

に与えられた撚が隣接糸同士の接触及び各糸層糸

うに作用するからであると思われる。 However, a: Length of width a of flat yarn (m) b: Length of thickness b of flat yarn (m) T: Number of twists per meter of length of flat yarn before self-twisting Number of twists like this By imparting this to the flat yarn, it becomes soft enough for the dye solution to pass through, and it is possible to cheese-wrap the yarn without the yarn layer collapsing during the winding and dyeing steps. The reason for this is thought to be that the twist given to the flat yarns acts to improve the hooking of the yarns when adjacent yarns come into contact with each other and when the yarns of each layer layer come into contact with each other.
撚回数Ｔが0.8／√＋より少ない場合は、
この引掛りが少なく、染液が通過し得る程度、即
ち一般的に巻密度が0.40g／cm3以下になるように

で糸層が崩れて染斑となる。 If the number of twists T is less than 0.8/√+,
It is difficult to wind the yarn to such a degree that there is little catching and the dye solution can pass through, that is, the winding density is generally less than 0.40 g/cm 3 , and even if it is possible, the yarn layer collapses during dyeing. It becomes a stain.

ｂ〜2.5／√＋である。 If the number of twists T is 4.0/√+ or more, it can be easily wound around a dyeing bobbin and dyed uniformly, but it is not possible to obtain a dyed yarn that has the shape and characteristics of a flat yarn, and it has a rounded shape. Only dyed thread can be obtained.
From the point of view of uniform dyeing and maintaining the characteristics of flat yarn, the more preferable range of twist number T is 1.5/√+
b~2.5/√+.

あるため本発明の範囲から除外される。 In the present invention, flat yarns include synthetic fibers such as polyester yarns, polyamide yarns, and polyacrylic yarns, flat yarns obtained using flat spinnerets of recycled or semi-synthetic fibers such as rayon, and cellulose acetate, and films. Any of flat threads that are cut to a certain width after molding, flat threads obtained by pressing thermoplastic synthetic fibers with heated rolls, and flat threads obtained by melting and adhering the surface of a multifilament can be used. The shapes of the flat threads are shown in Figures 1, 2, and 3.
As shown in the cross-sectional view in the figure, the cross-section may be rectangular, both ends rounded, multifilament integrated, etc., but the width a shown in the figure is 0.2 mm to 2 mm. , and the width a is the thickness b
It is necessary that it is 5 times or more. Width a is 0.2
If it is less than mm, it is not obvious to the naked eye whether it is a flat thread or not. That is, it does not have any characteristics as a flat thread. When the width a is 2 mm or more, it is difficult to apply the twists evenly within the range specified by the present invention, and it is difficult to obtain a flat yarn of good quality.
Flat yarns whose width a is less than 5 times the thickness b have air gaps between the wound yarns, so they are hard to the touch and have a low winding density, making it easy to dye uniformly. Therefore, they are excluded from the scope of the present invention.
次に実施例を示す。 Next, examples will be shown.

た糸となり商品価値の低い糸となつた。 The wound flat yarn was loaded into a cheese dyeing machine and dyed at 100°C according to a conventional method. The obtained dyed yarn was a uniformly dyed yarn with almost no difference in gloss, texture, etc. compared to untwisted skein-dyed yarn. For comparison, it was impossible to wind more than 100 g of flat yarn twisted at 30 twists per meter, which is outside the scope of the present invention, onto a dyeing bobbin. Moreover, when the yarn was twisted more than 170 times/m, it did not lose its luster as a flat yarn and became a rounded yarn with low commercial value.

As shown in the figure, 600 denier rayon thread with a width of 1.7 mm and a thickness of 0.03 mm is twisted at a rate of 50 times/m, and 600 g is put into a cheese dyeing tube with an outer diameter of 6.0 mm using an SP winder.
I wound the thread. The winding density was 0.36 g/cm 3 . The wound flat yarn was loaded into a cheese dyeing machine and dyed according to a conventional method. The obtained dyed yarn was a uniformly dyed yarn with almost no difference in gloss, texture, etc. compared to non-twisted skein dyed yarn. For comparison, the flat yarn twisted at 19 turns/m outside the scope of the present invention was 0.36 g/cm 3
Although it was possible to wind the yarn at a winding density of , the dyed medium yarn layer collapsed, resulting in dyeing spots, and the twisting occurred in places where the flat yarn was rubbed such as the yarn guide during the winding process of the cheese dyeing tube. The fibers moved, resulting in an unevenly twisted state and did not have uniform properties. On the other hand, 100
Flat yarns twisted more than once/m had a rounded appearance and had very different luster, texture, etc.
