Description

【0001】
【産業上の利用分野】
本発明は,セルロース系繊維を含有する布帛またはその縫製品に,遊離ホルムアルデヒドを残留させることなく,イージーケア性,パーマネントプレス性,防縮性を付与する加工方法に関するものである。
【0002】
【従来の技術】
セルロース系繊維布帛にホルムアルデヒドガスを気相状態で吸着せしめて,ホルムアルデヒドを繊維のセルロース分子間に架橋せしめることにより,セルロース系繊維布帛にイージーケア性(ウォッシュ・アンド・ウェアー性)を付与する加工方法は従来から公知であり,広く一般に行われている。
しかしながら,この方法による欠点は,加工後の布帛にホルムアルデヒドが残留してしまう点にある。加工後の布帛にホルムアルデヒドが残留しないようにするためには,加工後に布帛をソーピングするような方法をとるとよいが,この場合,そのための工程を余分に必要とし,しかも,ホルムアルデヒドを完全に除去することは非常に難しく,縫製品の場合には,再度プレスをしなければならないという問題点があった。
【0003】
【発明が解決しようとする課題】
本発明はこのような現状に鑑みて行われたもので,セルロース系繊維布帛に,遊離ホルムアルデヒドが残留することなく,優れたイージーケア性能,パーマネントプレス性能,防縮性能を付与する加工方法を得ることを第1の目的とするものであり,また,前述の布帛を用いた縫製品に,遊離ホルムアルデヒドを残留せしめることなく,優れた形態保持性,パッカリング性,プリーツ保持性を付与する加工方法を得ることを第2の目的とするものである。
【0004】
【課題を解決するための手段】
本発明は、上記目的を達成するもので、次の構成よりなるものである。すなわち、本発明は、セルロース系繊維を含有する布帛に、セルロース繊維に反応し得る架橋剤をパッダーにて付与し、しかる後に気相加工装置を用いて、気相化またはミスト化した触媒を触媒濃度0.1〜3.0%として吸着せしめ、熱処理して架橋剤を架橋せしめることを特徴とするセルロース系繊維布帛の加工方法を要旨とするものである。また、セルロース系繊維を含有する布帛に、セルロース繊維に反応し得る架橋剤をパッダーにて付与し、縫製品を形成し、しかる後に気相加工装置を用いて、気相化またはミスト化した触媒を触媒濃度0.1〜3.0%として吸着せしめ、熱処理して架橋剤を架橋せしめることを特徴とするセルロース系繊維布帛縫製品の加工方法も要旨とするものである。以下、本発明について詳細に説明する。
【0005】
本発明でいうセルロース系繊維を含有する布帛とは,木綿,麻,レーヨンなどの通常のセルロースよりなる繊維の1種または2種以上の混用からなる織物,編物,不織布等の布帛またはこれらの繊維とポリエステル,ポリアミド,ポリアクリロニトリルなどの合成繊維との混用(混紡,混繊,交織,交編等)からなる織物,編物を意味するものである。勿論,セルロース系繊維100%よりなる布帛であってもよい。
【0006】
本発明方法では,まず,上記の布帛にセルロース繊維と反応し得る架橋剤を付与する。
ここで用いるセルロース繊維と反応し得る架橋剤としては,ジメチルヒドロキシエチレン尿素等のアミド系化合物,トルエンジイソシアネート,メチレンビスパラフェニルイソシアネート,ヘキサメチレンジイソシアネート等のウレタン系化合物,ビスヒドロキシエタンスルホン,ビスヒドロキシエタンスルホンジサルフェート等のビニールスルホン系化合物,エピクロルヒドリン,グリセリンジグリシジルエーテル等のエポキシ系化合物,ブタンテトラカルボン酸等のポリカルボン酸系化合物やその他ハロゲン化多価アルコール化合物,クロルトリアジン系化合物,アセタール系化合物等を挙げることができる。
【0007】
上記の樹脂を布帛に付与するには,上記架橋剤を水に溶解し,必要に応じて柔軟剤を混合した水溶液を,通常の方法で布帛に含浸し,乾燥させる。実用的にはパッダー,コーター等で付着量をコントロールして付与することが好ましい。
架橋剤付与後,本発明では,必要に応じて架橋剤の付与された布帛を用いて縫製品を形成する。縫製は,通常の方法で行えばよい。
【0008】
本発明では,架橋剤の付与された布帛やその縫製品に気相化またはミスト化した触媒を吸着せしめ,熱処理して架橋剤を架橋せしめる。
この加工に際しては,常圧密閉型の反応室と,その内部にガスやミストの噴射供給手段,ヒーター等の加熱手段を有する気相加工装置を用いることができる。この場合,ATP社(American Textile Processing Co.)製の気相加工装置を用いることもできる。
【0009】
ここで用いる触媒の種類としては,例えば,硝酸亜鉛のような酸の金属塩,ルイス酸,ブレンステッド酸,水酸化ナトリウム,塩化水素,亜硫酸,ほう沸化亜鉛等を挙げることができる。
通常は,水溶液の形で霧状にミスト化して用いるが,そのまま気化するものはガスとして用いる。触媒をガス状で用いるために気化させる場合は,塩化水素のような揮発性の沸点の低い酸を用いることが望ましい。
【0010】
触媒濃度に関しては,0.1〜3.0%の範囲が望ましい。ガス濃度が0.1%以下であると,架橋反応が不十分となり,また,3.0%以上になっても,それ以上効果があがらなくなり,過度の生地強度の低下も発生するので注意を要する。
【0011】
布帛やその縫製品に触媒を吸着させたあと,熱処理して架橋剤の架橋反応を行う。この熱処理は,100〜180℃の範囲の温度で,0.5〜10分間の処理を行うことにより架橋反応を完結することができる。
本発明は,以上の構成よりなるものである。
【0012】
【作用】
本発明のごとく,セルロース系繊維を含有する布帛やその縫製品に,セルロース繊維に反応し得るホルムアルデヒド等の架橋剤を付与した後,これに気相化またはミスト化した触媒を吸着,熱処理する触媒による気相処理を行うと,ホルムアルデヒド等の架橋剤は,十分に与えられた触媒によってあますところなくセルロースと架橋結合するようになるので,未反応の遊離のアルデヒド等の架橋剤を布帛や縫製品に残存させることなく,優れたイージーケア性,パーマネントプレス性,防縮性をセルロース系繊維布帛やその縫製品に付与することができるようになる。

[Industrial applications]
The present invention relates to a processing method for imparting easy-care properties, permanent press properties, and shrink-proof properties to a fabric containing cellulosic fibers or a sewn product thereof without leaving free formaldehyde.
[0002]
[Prior art]
A process for imparting easy-care properties (wash and wear properties) to cellulosic fiber fabrics by adsorbing formaldehyde gas in the gaseous phase on the cellulosic fiber fabric and crosslinking formaldehyde between the cellulose molecules of the fibers. Is well known in the art and is widely practiced.
However, a disadvantage of this method is that formaldehyde remains in the processed fabric. In order to prevent formaldehyde from remaining in the processed fabric, it is advisable to take a method of soaping the fabric after the processing. In this case, however, an extra step is required, and the formaldehyde is completely removed. It is very difficult to perform the sewing, and in the case of a sewn product, there is a problem that the press must be performed again.
[0003]
[Problems to be solved by the invention]
The present invention has been made in view of the above situation, and provides a processing method for imparting excellent easy-care performance, permanent press performance, and shrink-proof performance to cellulose-based fiber cloth without free formaldehyde remaining. And a processing method for imparting excellent form retention, puckering and pleating properties to a sewn product using the aforementioned fabric without leaving free formaldehyde. It is a second object to obtain.
[0004]
[Means for Solving the Problems]
The present invention achieves the above object and has the following configuration. That is, the present invention is the fabric containing cellulosic fibers, crosslinking agent capable of reacting cellulose fiber imparted with padder, and using a vapor phase processing apparatus after mowing, a gaseous phase or mist catalyst The gist of the present invention is a method for processing a cellulosic fiber cloth, which comprises adsorbing at a catalyst concentration of 0.1 to 3.0% and heat-treating to crosslink the crosslinking agent. Further, a cross-linking agent capable of reacting with the cellulose fiber is applied to the cloth containing the cellulosic fiber with a padder to form a sewn product, and thereafter, the gas phase-formed or mist-formed catalyst is formed using a gas phase processing apparatus. A method for processing a sewn product of a cellulosic fiber fabric, characterized in that the catalyst is adsorbed at a catalyst concentration of 0.1 to 3.0%, and heat treatment is performed to crosslink the crosslinking agent. Hereinafter, the present invention will be described in detail.
[0005]
The fabric containing cellulosic fibers referred to in the present invention refers to a fabric such as a woven fabric, a knitted fabric, a non-woven fabric, or a fabric made of a mixture of one or two or more fibers of ordinary cellulose such as cotton, hemp, and rayon. Means a woven or knitted fabric composed of a mixture of a polyester and a synthetic fiber such as polyester, polyamide and polyacrylonitrile (blended, mixed fiber, mixed weave, mixed knit, etc.). Needless to say, the cloth may be made of 100% cellulose fiber.
[0006]
In the method of the present invention, first, a crosslinking agent capable of reacting with the cellulose fiber is applied to the above-mentioned cloth.
Examples of the crosslinking agent capable of reacting with the cellulose fibers used herein include amide compounds such as dimethylhydroxyethylene urea, urethane compounds such as toluene diisocyanate, methylenebisparaphenyl isocyanate, hexamethylene diisocyanate, bishydroxyethanesulfone, and bishydroxyethane. Vinyl sulfone compounds such as sulfone disulfate; epoxy compounds such as epichlorohydrin and glycerin diglycidyl ether; polycarboxylic acid compounds such as butanetetracarboxylic acid; other halogenated polyhydric alcohol compounds; chlorotriazine compounds; and acetal compounds. And the like.
[0007]
In order to apply the resin to the fabric, the crosslinking agent is dissolved in water, and the fabric is impregnated with an aqueous solution containing a softener as necessary, and dried. Practically, it is preferable to control the amount of adhesion with a padder, coater or the like.
After the cross-linking agent is applied, in the present invention, a sewn product is formed using the cloth to which the cross-linking agent has been applied as necessary. Sewing may be performed by a normal method.
[0008]
In the present invention, a gas-phased or mist-formed catalyst is adsorbed to a cloth or a sewn product to which a cross-linking agent has been applied, and heat treatment is performed to cross-link the cross-linking agent.
For this processing, a gas-phase processing apparatus having a normal-pressure closed-type reaction chamber and a gas or mist injection supply means and a heating means such as a heater therein can be used. In this case, a gas phase processing apparatus manufactured by ATP (American Textile Processing Co.) may be used.
[0009]
Examples of the type of catalyst used here include metal salts of acids such as zinc nitrate, Lewis acids, Bronsted acids, sodium hydroxide, hydrogen chloride, sulfurous acid, zinc borate and the like.
Usually, it is used in the form of a mist in the form of an aqueous solution in the form of a mist. If the catalyst is to be vaporized for use in gaseous form, it is desirable to use a volatile, low boiling acid such as hydrogen chloride.
[0010]
Regarding the catalyst concentration, a range of 0.1 to 3.0% is desirable. If the gas concentration is less than 0.1%, the crosslinking reaction becomes insufficient, and if the gas concentration becomes more than 3.0%, the effect will not be improved any more and an excessive decrease in fabric strength will occur. It costs.
[0011]
After the catalyst is adsorbed on the fabric or the sewn product, heat treatment is performed to perform a crosslinking reaction of the crosslinking agent. This heat treatment can complete the crosslinking reaction by performing the treatment at a temperature in the range of 100 to 180 ° C. for 0.5 to 10 minutes.
The present invention has the above configuration.
[0012]
[Action]
As described in the present invention, a catalyst which gives a cross-linking agent such as formaldehyde which can react with cellulosic fibers to a cloth or a sewn product containing the cellulosic fibers, and then adsorbs and heat-treats the vaporized or mist-formed catalyst. The cross-linking agent such as formaldehyde can be cross-linked to cellulose by the catalyst provided by a sufficiently supplied catalyst. Excellent easy-care properties, permanent press properties, and shrink-proof properties can be imparted to cellulosic fiber fabrics and sewn products without leaving them in the product.
