本発明はジーンズの脱色方法に係り、特に風合の良好な
ジーンズを工業的有利に得ることができるジーンズの脱
色方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method of bleaching jeans, and particularly to a method of bleaching jeans that can industrially advantageously produce jeans with a good feel.
［従来の技術］
従来より、ジーンズは幅広い世代に浸透し、近年、染色
・縫製しただけのジーンズと共に、使い古し感覚のある
色落ちしたジーンズも流行している。[Prior Art] Jeans have long been popular among a wide range of generations, and in recent years, along with jeans that have only been dyed and sewn, faded jeans that have a worn-out feel have become popular.
介卑 缶荒飢１、外ぐンー〜ノブＬ十 壬妖Ｌ−庵田十
ス軽石をメディアとして用い、回転バレル内で水及び染
色・縫製したジーンズと共に回転して使い古しの風合に
脱色して製造されている。この方法による脱色の原理は
次の通りである。Using pumice stone as a media, it is rotated in a rotating barrel with water and dyed and sewn jeans to bleach it to a worn-out texture. Manufactured by The principle of decolorization by this method is as follows.
即ち、ジーンズは吸水するとその表面に襞が形成される
。回転バレルの動作中に、襞の凸部はメディアによって
摩耗が進み脱色するが、凹部は摩耗が少ない。これによ
フて、微妙な風合を持った自然な脱色ができる。That is, when jeans absorb water, wrinkles are formed on the surface of the jeans. During operation of the rotating barrel, the convex portions of the folds are worn down by the media and become discolored, but the concave portions are less worn. This allows for natural bleaching with a subtle texture.
このようなことから、メディアとして、みかげ石（嵩比
重２．５〜２．８）の様に重いものを用いた場合には、
吸水時の襞の凸凹に対して脱色操作中にメディアが強く

．９〜１．８（実測値で１．３〜１．６）のものであれ
ば、吸水時の襞を生かした脱色が可能であるため、従来
、ジーンズ脱色のメディアとしては、主に玉石と称され
る嵩比重１．３前後の火山軽石を用いている。For this reason, if a heavy material such as granite (bulk specific gravity 2.5 to 2.8) is used as the media,
During the decolorization process, the media strongly hits the unevenness of the folds during water absorption, which flattens the unevenness and prevents natural uneven bleaching. On the other hand, like pumice, the bulk specific gravity is 0.
．． 9 to 1.8 (Actually measured value is 1.3 to 1.6), it is possible to bleach the jeans by taking advantage of the folds during water absorption. Volcanic pumice with a bulk specific gravity of around 1.3 is used.
［発明が解決しようとする問題点］
しかしながら、軽石を用いた場合には次のような欠点が
あった。[Problems to be Solved by the Invention] However, the use of pumice had the following drawbacks.
■ 軽石は脆性材料で耐摩耗性が低いため、回転処理中
に摩耗して、処理後の排水時に多量の土砂（摩耗物）が
発生し、排水処理が困難となる。例えば、通常の脱色処
理において、ジーンズ１本当り約ＩＫｇの土砂が発生す
る。■ Pumice is a brittle material and has low abrasion resistance, so it wears down during rotation treatment and generates a large amount of earth and sand (wearing material) when draining water after treatment, making wastewater treatment difficult. For example, in a normal bleaching process, approximately I kg of dirt is generated per pair of jeans.
■ 同様の理由から、ジーンズのポケットや縫目等に大
量の土砂が付着し、脱色後のジーンズの洗浄処理が困難
となる。■ For the same reason, a large amount of dirt adheres to the pockets and seams of jeans, making it difficult to wash the jeans after bleaching.
■ このように摩耗が多いため、メディアの補充を頻繁
に行なわなければならず、脱色作業が繁雑となる上に、
経済的にも不利となる。■ Due to this high amount of wear, the media must be replenished frequently, making decoloring work complicated, and
It is also economically disadvantageous.
■ 軽石は天然物であるため、硬度４、粒度、比重が変
化し易く、管理が容易ではなく、安定した脱色を行なう
ことが困難である。■ Since pumice is a natural product, it has a hardness of 4, particle size, and specific gravity that change easily, making it difficult to manage and to perform stable decolorization.
■ 天然物に由来する鉄分のような変色物置により、ジ
ーンズが汚染されることがある。■ Jeans can be contaminated by natural sources of discoloration, such as iron.

ジーンズの脱色方法、を要旨とするものである。[Means for Solving the Problems] The present invention solves the above-mentioned conventional problems, and provides a glass having a bulk specific gravity of 0.7 to 1.2, a 24-hour water absorption rate of 5% or less, and a maximum diameter of 150 mm or less. The gist of this invention is a method for decolorizing jeans, which is characterized by rotating foamed ceramics, water, and jeans in a rotating tank.
以下に本発明の詳細な説明する。The present invention will be explained in detail below.

ンズを得ることができない、嵩比重は特に約１程度であ
ることが好ましい。The bulk specific gravity of the glass foam ceramic is a factor that affects the degree of bleaching of jeans, and if the bulk specific gravity is less than 0.7, sufficient bleaching efficiency cannot be obtained. On the other hand, the bulk specific gravity is 1.2
If it exceeds 1, the degree of collision with the folds of the jeans during water absorption is too large, making it impossible to obtain jeans with a good texture by decolorizing the folds.The bulk specific gravity is particularly preferably about 1.

ラス発泡性セラミックスの２４時間吸水率は５％以下、
好ましくは１％以下とする。If the water absorption rate of the glass foam ceramic is too high, the specific gravity will increase due to water absorption, and it may not be possible to perform decolorization that takes advantage of the folds of jeans. Therefore, in the present invention, the 24-hour water absorption rate of glass foam ceramics is 5% or less,
Preferably it is 1% or less.

It is not particularly limited, and can have various shapes such as a sphere, an ellipse, and a polyhedron. Also, for example, the diameter is 10 to 80 mm and the length is 10 to 80 mm.
A cylindrical or approximately cylindrical shape of about 150 mm can also be used.

Using a ball mill-shaped barrel 1 as shown in (schematic side view) and (b) (front view), glass foam ceramics, water, and jeans are charged into the barrel 1 through the input port 2 and rotated.

適宜決定される。In this case, the proportions of the glass foam ceramics, water, and jeans to be added vary depending on the physical properties of the glass foam ceramics and the degree of bleaching of the jeans, but in general,
1 to 1 glass foam ceramics per pair of jeans
It is preferable to add 20 kg and 1 to 10 L of water. The rotation time and rotation speed of the barrel are also appropriately determined depending on the physical properties of the glass foam ceramics used, the charging ratio, the degree of decolorization, and the like.
このようにして脱色されたジーンズは、洗浄等の後処理

［作用］
ガラス発泡性セラミックスは軽石等に比し硬度が高く脆
くないため、摩耗し難い。[Function] Glass foam ceramics have higher hardness and are less brittle than pumice, so they are less likely to wear out.
このため摩耗による土砂の発生が低減され、排水処理や
ジーンズの仕上げ処理が容易となる。しかも、摩耗量相
当分の補給量も少なくてよいため、補給作業等が軽減さ
れ、効率が向上する。Therefore, the generation of dirt and sand due to wear is reduced, making it easier to treat wastewater and finish jeans. Furthermore, since the amount of replenishment corresponding to the amount of wear only needs to be small, replenishment work and the like are reduced and efficiency is improved.

You can get good quality jeans.
更に、天然物に由来する鉄分等の変色物質が処理系に混
入することがないので、ジーンズの汚染が防止される。Furthermore, since discoloration substances such as iron derived from natural substances are not mixed into the treatment system, contamination of the jeans is prevented.
