Description
従来の綿繊維（以下これを綿布として説明する。）の一般的漂白処理は、その漂白を行なう前の綿布の糊抜き、精練の処理を行なった後に、その綿布の漂白を行なう。この漂白処理は、通常漂白剤として亜塩素酸ソーダを用いる漂白法が採用されている。この漂白方法では布地を傷めることが少なく、しかも高い漂白度が得られるので、この亜塩素酸ソーダ使用による漂白法が一般的に行なわれている。 In the general bleaching treatment of conventional cotton fibers (hereinafter, this will be described as cotton cloth), the cotton cloth is bleached after the cotton cloth is deglued and refined before the bleaching. The bleaching, bleach method has been adopted as a normal bleach used chlorite soda. Since this bleaching method does not damage the fabric and a high degree of bleaching can be obtained, the bleaching method using this sodium chlorate is generally performed.
それは、オゾン含有ガスを用いた漂白後において、経時的黄変が生じるということである。つまりオゾン含有ガスを使用する綿布の漂白は、その漂白直後では高い白度が得られるが、その漂白後、数週間から数ケ月経過すると徐々に黄変度が高まることが判明された。この黄変度は、漂白直後の綿布を、蒸気か熱処理あるいはアルカリ処理を行なうことで直ちに現われる。 It, after the bleaching with ozone-containing gas is that over time yellowing occurs. In other words, it was found that the bleaching of cotton cloth using ozone-containing gas gives a high degree of whiteness immediately after the bleaching, but the degree of yellowing gradually increases several weeks to several months after the bleaching. This yellowing is a cotton fabric after bleaching, immediately appears by performing a vapor or thermal treatment or alkali treatment.
かくしてオゾン処理室５内でオゾン処理された布帛１は、そのオゾン処理室５から導出された後、湯温が８０℃〜１００℃に保たれている湯洗槽６内に供給され、この湯洗槽による湯洗作用によって布帛１の繊維はオゾンと反応し、この反応時に生じた酸化セルローズの一部が繊維から洗い落される。この湯洗浄時間は３０秒から数分が望ましい。 The cloth 1 thus ozone-treated in the ozone treatment chamber 5 is led out from the ozone treatment chamber 5 and then supplied to the hot water washing tank 6 in which the hot water temperature is maintained at 80 ° C. to 100 ° C. The fibers of the cloth 1 react with ozone by the hot water washing action of the washing tank, and a part of the oxidized cellulose generated during this reaction is washed off from the fibers. The hot water washing time is preferably 30 seconds to several minutes.
