本発明は、セルローズ系布帛を基にして、適度の透明度
と、風合を具備せしめることができる布帛の硫酸処理方
法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method of treating a cellulose-based fabric with sulfuric acid, which can impart appropriate transparency and texture to the fabric.
（従来の技術）
セルローズ系ｌａ １１布帛を硫酸で処理することによ

溶液を使用して行なっているもので、布帛に適度の透明
感を得る反面、風合が硬くなって、あたかも麻布の如き
感触が得られる。(Prior art) Cellulose-based LA 11 fabric is treated with sulfuric acid to change its texture and transparency, and is numerically referred to as organdy processing and is a process for obtaining linen-like fabric. Effective as processing. The conventional TA acid treatment (organdy treatment) of cellulose fiber fabric is 51.5°Be'
This method uses a solution of ~52°Be sulfuric acid mixed with phosphoric acid, formalin, etc., and while it gives the fabric a moderate degree of transparency, it also makes the texture stiffer, making it feel like linen cloth. It will be done.
ところが、その硫酸処理布の透明度を高めようとすると
、その布帛の風合が増々硬化して、衣服用の生地として
適さなくなり、例えば衣服の芯地にしか適さない程硬化
してしまう。すなわち、オーガンジ加工は、強酸を用い
て処理するものであるために、反応が迅速であって、透
明感を出す程、必要以上に硬くなるもので、透明度と希
望する風合とのバランスが取り難いものであった。However, if an attempt is made to increase the transparency of the sulfuric acid-treated fabric, the texture of the fabric becomes increasingly hardened, making it unsuitable as a fabric for clothing, and hardening to such an extent that it is only suitable for interlining, for example, clothing. In other words, since organdy processing uses strong acid, the reaction is rapid, and the more transparent it becomes, the harder it becomes than necessary, so it is difficult to balance transparency with the desired texture. It was difficult.
（課題を解決するための手段）
本発明はかかることに着目してなされたものであって、
適度の透明感と風合を備えた布帛を得るためになされた
布帛の硫酸処理方法で、具体的には、セルローズ系布帛

優れた硫酸処理加工布帛を得ることができる。(Means for Solving the Problems) The present invention has been made focusing on the above,
This is a method of treating fabric with sulfuric acid to obtain fabric with appropriate transparency and texture.Specifically, 0.25
By adding ~0.5% of urea, a sulfuric acid-treated fabric with excellent texture and transparency can be obtained.
すなわち、尿素は硫酸酸中で有機塩基として働くので尿

ある。That is, since urea acts as an organic base in sulfuric acid, if the amount of urea added is excessive, sulfuric acid will no longer act as a strong acid on cellulose fibers, making organdy processing impossible. The amount of urea added is up to 1.5% based on the sulfuric acid solution. Above that amount, the sulfuric acid reaction will not occur. Changes in hardness and softness were measured using the Hartloop method, and the results were as follows: untreated fabric 8';
Omm, 601nm when treated with sulfuric acid solution that does not contain urea,
70 mm for treatment containing 0.25-0.5% urea, urea 1
75) in the treatment containing ~1.5% of urea, and 80non in the treatment containing 2% of urea, and no sulfuric acid reaction of cellulose fibers occurs when 2% of urea is included in the sulfuric acid solution. Therefore, the preferred amount of urea added is 0.25 to 0.5% of the sulfuric acid treatment Z capacity.
（実 施 例）
常法により糊抜精練漂白を施した綿１００％ローンを使

By setting the amount of urea added as shown in 3, the action of the strong acid becomes softer, making it possible to make the fibers transparent while suppressing them from hardening. This method has the effect of making it possible to produce organdy products with a high quality.
