る。2. Description of the Related Art The factors that cause color streaks in woven and knitted cotton are:
Although it is caused by raw cotton, spinning, weaving, dyeing, etc., the term "color gradation" as used herein means that caused by raw cotton. The color step caused by the raw cotton occurs when the raw cotton is woven and knitted with yarns having different maturity levels. In the case of batch dyeing, particularly many color steps occur. As a method for preventing the color step, measures such as refining, bleaching, and strengthening the mercerizing condition may be taken, but the color step cannot be prevented. There are methods such as dye selection or devising dyeing conditions, but this is not perfect. Also, the woven and knitted fabrics are cut, the strength of the color stage after dyeing is divided in advance, and the fabric with strong color stages is put into the bleaching to relieve.
Manpower is required for dyeing and sorting, which leads to increased costs.

編物に低温プラズマ処理を行う。In the present invention, a woven or knitted fabric made of cotton is used as a target of the color step prevention method. The pretreatment step referred to in the present invention is not a special step and is usually carried out, and includes, for example, calcination, scouring, bleaching and mercerizing steps.

The apparatus described on page 188 of (1985) can be used. This device has a structure in which a pair of electrodes for discharge are installed in a vacuum container that can maintain a low pressure, a specific gas can be introduced at a predetermined flow rate, and the inside of the container can be evacuated by an attached vacuum pump to maintain a constant pressure. It is a device with the performance. When a voltage is applied to the electrodes in this device, glow discharge is caused and the introduced gas becomes a low temperature plasma state. Most commonly, a high frequency power of 13.56 MH is applied.
The low temperature plasma treatment can be performed by passing the cloth (woven or knitted fabric) to be treated at a desired speed in a low temperature plasma atmosphere formed between the electrodes.

ある。Specifically, first, the cloth to be treated is housed in a vacuum container, exhausted and decompressed by a vacuum pump, and the internal pressure is adjusted to 0.01 to 10 Torr. Then, a predetermined gas is introduced to adjust the pressure to 0.1 to 5 Torr. As the gas used at this time, various gases such as oxygen, nitrogen, argon, helium, ammonia and air can be used. Usually oxygen, air and argon are preferred. When high frequency power is applied to the electrodes in the container with a predetermined gas introduced and adjusted to 0.1 to 5 Torr, the introduced gas becomes a low temperature plasma state. High frequency power is 0.1-5w / cm 2
The (electrode unit area) level is appropriate. The low-temperature plasma treatment can be performed by passing the cloth stored in advance in the low-temperature plasma atmosphere. The treatment time is usually several seconds to 300 seconds, preferably 30 to 180 seconds.

述の低温プラズマ処理を行った後染色することにより、
色段の改善された織編物を得ることができる。Dyeing is performed after the above-mentioned low-temperature plasma treatment. The dyeing referred to in the present invention means, for example, batch dyeing using a Wins jet dyeing machine. Examples of the dye used include reactive dyes, vat dyes, naphthol dyes and the like. The dyeing process in the present invention is not a special process, and a process that is usually performed on a cloth can be adopted. By dyeing after performing the above-mentioned low temperature plasma treatment,
It is possible to obtain a woven or knitted fabric with an improved color gradation.

さらに具体的に説明する。The reason why the low-temperature plasma treatment in the present invention can prevent the color step of the woven or knitted fabric made of cotton is as follows.
It is not always clear, but it is speculated as follows. That is, it is speculated that the low-temperature plasma treatment of cotton increases the proportion of the immature fibers that change to the amorphous regions compared to the mature fibers, and as a result, the difference in dyeing between the immature fibers and the mature fibers is reduced. . Next, the present invention will be described more specifically by way of examples.
