Clothes with W&W properties do not wrinkle when worn, and can be worn without ironing after washing and are easy to handle. Various treatments have been conventionally carried out to impart WAW properties to cellulose-based fiber structures. For example, a resin processing method that uses cellulose fiber-reactive resin and performs dry heat treatment with an acidic catalyst.

（本発明が解決しようとする問題点） しかしこの様な従来の方法には種々の欠点がある。(Problems to be solved by the present invention) However, such conventional methods have various drawbacks.
例えば乾熱処理による樹脂加工方法では乾防皺性に比べ
て、湿防皺性が低く、充分なＷ＆Ｗ性が得られず、Ｗ＆
Ｗ性を上げるために樹脂濃度を高くすると風合が硬くな
ったり、強力の低下が大きくなったりする欠点がある。For example, in the resin processing method using dry heat treatment, the moisture wrinkle resistance is lower than the dry wrinkle resistance, and sufficient W&W properties cannot be obtained.
If the resin concentration is increased in order to improve the W properties, there are drawbacks such as a hard texture and a significant decrease in strength.
又、湿式架橋と乾式架橋による二段加工法ではある程度
のＷ＆Ｗ性は得られるが不充分であり、工程が複雑で、
性能が安定せず、２段加工による強力の低下も大きいと
いう欠点がある。又、ホルマリンによる処理方法では、
強い酸性触媒を使用するために、染料の変色や機台の腐
食が強く、気相処理では特別な装置が必要であり、更に
衣料としてホルマリンの発生が大きく、強力の低下も大
きいという欠点がある。In addition, although a certain degree of W&W properties can be obtained using a two-step processing method using wet crosslinking and dry crosslinking, it is insufficient and the process is complicated.
The disadvantage is that the performance is not stable and the strength is greatly reduced due to two-stage processing. In addition, in the formalin treatment method,
Due to the use of a strong acidic catalyst, there is strong discoloration of the dye and corrosion of the machine, special equipment is required for gas phase treatment, and there is also a disadvantage that a large amount of formalin is generated when used for clothing, and the strength is greatly reduced. .
又、モイストキュアー法では、強酸性触媒の使用による
機台の腐食や、水分率のコントロールが困難であり、又
有機溶剤の使用も実用上の困難性が大きいという欠点が
ある。Furthermore, the moist cure method has drawbacks such as corrosion of the machine base due to the use of a strong acidic catalyst, difficulty in controlling the moisture content, and practical difficulties in the use of organic solvents.
更に、低ピックアップ率加工では、本来の樹脂加工自体
が不充分であり、Ｗ＆Ｗ性が得られない。Furthermore, with low pickup rate processing, the original resin processing itself is insufficient, and W&W properties cannot be obtained.
本発明は従来行なわれているＷ＆Ｗ性付与加工に比較し
、筒車な処理剤により、特別な装置も必要とせずに加工

ものである。Compared to the conventional W&W properties imparting process, the present invention can be processed without the need for special equipment using a special processing agent, and has excellent wrinkle resistance both when dry and wet, and has a strong The object of the present invention is to establish a processing method for imparting WAW properties to a cellulose fiber structure with no deterioration and a good texture.

Examples of cellulose fibers include cotton, hemp, and plant bast. There are fibers, leaf fibers, regenerated cellulose fibers such as rayon, polynosic, cupro, etc., but it is particularly effective for those containing 2/3 or more of the fiber structure weight of cotton or hemp.
以下、第１の発明について詳説する。The first invention will be explained in detail below.

濃度２０〜２８重量％程度の苛性ソーダ溶液中に３０秒
〜１分間程度浸漬する方法等が挙げられる。The cellulose-based fiber structure is first subjected to mercerization. The mercerization may be performed by a known method, such as immersion in a caustic soda solution having a concentration of about 20 to 28% by weight for about 30 seconds to 1 minute.

Alkaline aqueous solutions are aqueous solutions of alkali metal or alkaline earth metal hydroxides, such as sodium hydroxide, potassium hydroxide, lithium hydroxide, cesium hydroxide, barium hydroxide, calcium hydroxide, and magnesium hydroxide. Particularly preferred are aqueous solutions of sodium hydroxide and potassium hydroxide.
