【発明の属する技術分野】
本発明は架橋改質されたセルロース系繊維を含有する布帛に関するものである。
【0002】
【従来の技術】
従来から、セルロース系繊維を含む布帛は、吸水性が高い、肌触りがよいなど様々な利点を有するため、衣料用途など多方面に幅広く利用されている。しかしながら、その一方で合成繊維布帛に比べ、しわになりやすい、洗濯により収縮するといった欠点があり、これらを改善する目的で、様々な加工が検討されている。なかでもホルムアルデヒドや繊維素反応型樹脂などの架橋剤を用い、セルロース系繊維を架橋改質することで、防しわ性、防縮性等の形態安定性能を付与する方法が広く行われているが、この改質を過度に行った場合、架橋の形成により布帛の柔軟性が低下するため、一般にはアミノ変性シリコーン系柔軟剤等による処理が必要である。しかしアミノ変性シリコーン等の柔軟剤を併用した場合、それらが疎水性であるため、それによって処理された布帛の吸水性が低下し、実際に衣料として着用した場合、吸汗性の悪い、着心地感の悪いものとなってしまうという問題があった。また、一方で架橋改質を十分に行わなかった場合には、必要とされるレベルの防しわ性、防縮性等の形態安定性能が付与することができないというのが現状である。
【0003】
【発明が解決しようとする課題】
本発明は、かかる背景に鑑み、防しわ性、防縮性等の形態安定性能と吸水性を兼ね備えたセルロース系繊維含有布帛を提供せんとするものである。
【0004】
【課題を解決するための手段】
本発明は、かかる課題を解決するため、次の構成を有する。
【0005】
すなわち、架橋改質されたセルロース系繊維を含有する布帛であって、該布帛の下記式で定義される架橋指数が1〜4、かつJIS L−1096バイレック法で測定した吸水性が50mm以上であることを特徴とするセルロース系繊維含有布帛。
【0006】
架橋指数=(A−B)
ここで A : 温度30℃、相対湿度90%RH雰囲気下での架橋改質後のセルロース系繊維の吸湿率(%)。
【0007】
B : 温度20℃、相対湿度65%RH雰囲気下での架橋改質後のセルロース系繊維の吸湿率(%)。
【0008】
【発明の実施の形態】
本発明でいうセルロース系繊維含有布帛とは、綿、麻、パルプなどの天然セルロース繊維、ビスコースレーヨンなどの再生セルロース繊維等を含有する布帛のことであり、ポリエチレンテレフタレートやポリブチレンテレフタレートなどのポリエステル系繊維、ナイロン6やナイロン66などのポリアミド系繊維、ポリエチレンやポリプロピレンなどのポリオレフィン系繊維、羊毛や絹などのタンパク質系繊維、ポリ塩化ビニル系繊維、ビニロン繊維、アセテート繊維などと混繊、混紡、交織、交編などにより混用するものも含まれる。なお、得られる効果の面からは、他の繊維と混用される場合、セルロース系繊維を繊維重量で10wt%以上含有するものであることが好ましい。
【0009】
架橋改質に用いる架橋剤は、セルロース系繊維を構成しているセルロース分子中の水酸基、とりわけ洗濯時のしわ、収縮の原因となる非晶領域にある水酸基と反応し、セルロース分子間および分子内に架橋を形成することが可能な化合物が好ましく用いられる。具体的にはホルムアルデヒドや、ジメチロールエチレン尿素、ジメチロールトリアゾン、ジメチロールウロン、ジメチロールグリオキザールモノウレイン、ジメチロールプロピレン尿素、これらのメチロール基の一部または全部をメトキシ化、エトキシ化したもの等の繊維素反応型樹脂、ポリカルボン酸類、イソシアネート類等があげられる。これらの架橋剤の中でも、セルロース系繊維の架橋改質をより効率的、効果的に行うために、本発明においては、下記一般式[I]で示された化合物が用いられる。
【0010】
【化2】
ここで R1、R2は−H、炭素数1〜4のアルキル基、又は−CH2OR7 のいずれかである同種又は異種の基。R3、R4、R5、R6は−Hまたは−OR8 のいずれかである同種又は異種の基。R7、R8は−H、又は炭素数1〜4のアルキル基のいずれかである同種又は異種の基。かかる架橋剤のセルロース系繊維への付与方法としては、一般の架橋手段が適用可能であり、具体的には架橋剤をガス状にして付与する方法、パディング法、浸漬法、スプレー法、プリント法、コーティング法、グラビア加工法、泡加工法等があげられるが、なかでも架橋剤が繊維素反応型樹脂、ポリカルボン酸類、イソシアネート類等の場合にはパディング法が好ましく使用される。
【0011】
かかる架橋剤によるセルロース系繊維の架橋改質の方法としては、一般の架橋改質方法が適用可能であり、具体的には、布帛の状態のままのセルロース系繊維含有布帛に対し上述の架橋剤を付与し、縫製した後、加熱処理を施すポストキュア法、布帛の状態のままのセルロース系繊維含有布帛に対し上述の架橋剤を付与して熱処理まで行うプレキュア法等があげられるがこれらに限定されるものではない。なお、熱処理温度としては80〜220℃の範囲にあることが好ましい。
【0012】
セルロース系繊維の架橋改質を行うにあたり、架橋剤の反応を促進する目的で、触媒を併用することも好ましく行われ、具体的には、有機酸、有機アミン塩、塩化マグネシウム、硝酸亜鉛、ホウフッ化亜鉛、硝酸マグネシウム、塩化亜鉛等の金属塩などを用いることができる。
【0013】
本発明のセルロース系繊維含有布帛はかかる方法により架橋改質されたセルロース系繊維を含むものであるが、その改質の程度は下記式で定義される架橋指数が1〜4の範囲内、より好ましくは2〜3.5の範囲内にあるものでなければならない。
【0014】
架橋指数=(A−B)
ここで A : 温度30℃、相対湿度90%RH雰囲気下での架橋改質後のセルロース系繊維の吸湿率(%)。
【0015】
B : 温度20℃、相対湿度65%RH雰囲気下での架橋改質後のセルロース系繊維の吸湿率(%)。
【0016】
かかる架橋指数は、架橋改質後のセルロース系繊維の温度30℃、相対湿度90%RH雰囲気下で吸湿率の値から温度20℃、相対湿度65%RH雰囲気下で吸湿率の値を差し引いて算出されるものであり、セルロース系繊維がどの程度架橋改質されているかを知る上での指標となる。すなわちこれは、架橋改質によりセルロース分子中の水酸基が封鎖され、結果として吸湿率の値が低下することを利用したものである。この指数が小さいものほど架橋改質の度合いが大きく、大きいものほど架橋改質の度合いが小さい。一般に未加工の木綿、麻で4〜5程度である。
【0017】
架橋指数が1より小さい場合、架橋が過度に形成され、布帛の強力や柔軟性が低下し、形態安定性は良好であるものの、実用に耐えないものとなってしまう。布帛の強力や柔軟性が低下する場合、それらを改善する目的で、一般にはアミノ変性シリコーン系柔軟剤等による処理が行われるが、アミノ変性シリコーン等の柔軟剤を併用した場合、それらが疎水性であるため、それによって処理された布帛の吸水性が低下し、実際に衣料として着用した場合、吸汗性の悪い、着心地感の悪いものとなってしまう。一方、架橋指数が4より大きい場合は、セルロース繊維の架橋改質が十分でなく、必要とされるレベルの防しわ性、防縮性等の形態安定性能が付与出来ない。布帛の強力、柔軟性と形態安定性のバランスを考えた場合には、架橋指数が2〜3.5の範囲内にあることがより好ましい。
【0018】
また、本発明のセルロース系繊維含有布帛はJIS L−1096バイレック法で測定した吸水性が50mm以上であるものである。吸水性が50mmに満たない場合、かかる布帛を縫製して得られた衣料は、吸汗性の悪い、着心地感の悪いものとなってしまう。
【0019】
本発明においては、布帛の柔軟性を向上させる目的で、シリコーン系柔軟剤を付与することも好ましく行われる。ただし、通常一般に用いられるシリコーン系柔軟剤、とりわけアミノアルキル基含有ポリシロキサンを主成分とするアミノ変性シリコーン系柔軟剤を用いて布帛を処理した場合、処理された布帛の柔軟性やその効果の耐久性は優れるものの、処理布帛が撥水性を示すようになり、本発明の防しわ性、防縮性等の形態安定性能と吸水性を兼ね備えたセルロース系繊維含有布帛に適用するには不向きである。
【0020】
従って、本発明におけるシリコーン系柔軟剤は布帛の吸水性を阻害することなく、柔軟な風合いを与えるものが好ましく、具体的には1分子中にアミノ基とポリオキシアルキル基の両方を含有するオルガノポリシロキサンと、分子中にアミンまたは水酸基と反応可能な基を少なくとも1個含有するポリエチレンポリアミン高級脂肪酸型アミド化合物とを主成分とするものであることが好ましい。
【0021】
該オルガノポリシロキサンは1分子中にアミノ基とポリオキシアルキル基の両方を含有するオルガノポリシロキサン、すなわちアミノポリエーテル変性シリコーンであれば特に限定されるものではないが、25℃における粘度が100〜100000cst、アミノ等量が300〜3000の範囲にあるものが好ましい。また、アミノポリエーテル変性シリコーンのアミノ基は、黄変防止のため該アミノ基と反応性を有する化合物、有機酸または有機酸の無水物もしくは塩化物等により該アミノ基の一部もしくは全部が封鎖されていてもよい。
【0022】
また、ポリエチレンポリアミン高級脂肪酸型アミド化合物としては、ポリエチレンポリアミン高級脂肪酸アミド、ポリエチレンポリアミン高級脂肪酸アミドの尿素縮合物、ポリエチレンポリアミン高級脂肪酸型アミド部分のイミダゾリニウム塩などとジカルボン酸、環状酸無水物、ジグリシジルエーテル、ジイソシアネート等との反応物などが挙げられる。
【0023】
これらの構成成分であるポリエチレンポリアミンとしては、ジエチレントリアミン、トリエチレンテトラミン、テトラエチレンベンタミン、アミノエチルエタノールアミンなどが挙げられる。高級脂肪酸としては、パーム油、牛脂、ナタネ油、米糠油、魚油などの天然油脂由来のものが一般的であるが、化学的に合成した高級脂肪酸も使用できる。これらのうち好ましいものは、ヨウ素価が50以下で炭素数が12〜24の高級脂肪酸である。ジカルボン酸、環状酸無水物としては、マレイン酸、無水マレイン酸、フマル酸、リンゴ酸、コハク酸、無水コハク酸、酒石酸、フタル酸、無水フタル酸などが挙げられる。ジグリシジルエーテルとしては、エチレングリコールジグリシジルエーテル、プロピレングリコールジグリシジルエーテル、ポリオキシアルキレングリコールジグリシジルエーテル、ネオペンチルグリコールジグリシジルエーテル、1,6−ヘキサンジオールジグリシジルエーテルなどが挙げられる。ジイソシアネートとしては、トリレンジイソシアネート、キシレンジイソシアネート、ジフェニルメタンジイソシアネート等の芳香族ジイソシアネート、テトラメチレンジイソシアネート、ヘキサメチレンジイソシアネート、リジンジイソシアネート等の脂肪族ジイソシアネートなどが挙げられる。
【0024】
ポリエチレンポリアミン高級脂肪酸型アミド化合物を構成するポリエチレンポリアミンと高級脂肪酸のモル比は、通常、1:1.0〜2.5、好ましくは1:1.2〜1.8である。
【0025】
かかるシリコーン系柔軟剤の主成分であるアミノポリエーテル変性シリコーンとポリエチレンポリアミン高級脂肪酸アミドの重量比は1:0.2〜1.5、好ましくは1:0.3〜1.0である。ポリエチレンポリアミン高級脂肪酸アミドが0.2未満の場合には十分な柔軟性が得られず、また、1.5を越える場合は処理された布帛の吸水性が低下するので好ましくない。
【0026】
かかるシリコーン系柔軟剤の繊維重量に対する付着量は、0.06〜1.0wt%の範囲であることが好ましい。付着量が0.06wt%未満の場合、布帛に十分な柔軟性、平滑性を付与することが困難であり、また1.0wt%より大きい場合には、柔軟性、平滑性は向上するものの、目ズレなどの欠点を引き起こす原因となる。
【0027】
本発明においては、布帛の吸水性を向上させる目的で親水性樹脂、好ましくは親水性ポリエステル樹脂を付与することも好ましく行われる。中でもポリアルキレングリコール−ポリエステルブロック共重合体を主成分とするものがよい。
【0028】
ここでいうポリアルキレングリコールとは分子中に −CnH2nO− (n=2〜4)なる主鎖を有するもののことをいい、具体的にはポリエチレングリコール、ポリプロピレングリコール、またはこれらのブロックポリマー等である。かかるポリアルキレングリコールの分子量は300〜40000の範囲にあることが好ましく、1000〜10000にあることがより好ましい。分子量が300に満たない場合は繊維への付着耐久性が不十分になる傾向にあり、分子量が40000を越えると分散性が低下する傾向にある。
【0029】
また、かかるポリアルキレングリコールをブロック共重合するポリエステルとしては、芳香族ジカルボン酸とアルキレングリコールからなるものが好ましい。芳香族ジカルボン酸としては、テレフタル酸、テレフタル酸の低級アルキルエステル、イソフタル酸、イソフタル酸の低級アルキルエステル等が挙げられ、アルキレングリコールとしては、エチレングリコール、プロピレングリコール、ブチレングリコール等が挙げられる。
【0030】
かかる親水性ポリエステル樹脂の繊維重量に対する付着量は、0.03〜1.0wt%の範囲であることが好ましい。付着量が0.03wt%未満の場合、親水性ポリエステル樹脂を付与したことによる効果は少なく、また1.0wt%より大きい場合には、布帛の吸水性は向上するものの、布帛にヌメリ感が起こり、また染色堅牢度低下の原因ともなる。
【0031】
本発明のセルロース系繊維含有布帛を用いてなる繊維製品は防しわ性、防縮性等の形態安定性、吸水性に優れており、ドレスシャツ、学童用スクールシャツ、ユニフォーム、婦人衣料、スポーツ衣料、等の用途に好適である。

BACKGROUND OF THE INVENTION
The present invention relates to a fabric containing a cellulosic fiber that has been crosslinked and modified.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, fabrics containing cellulosic fibers have various advantages such as high water absorption and good touch, and thus are widely used in various fields such as clothing. On the other hand, however, there are drawbacks such as wrinkles and shrinkage due to washing as compared with synthetic fiber fabrics, and various processes have been studied for the purpose of improving these. Among them, a method for imparting shape stability performance such as wrinkle resistance and shrinkage resistance is widely performed by using a crosslinking agent such as formaldehyde or a fibrin-reactive resin to crosslink and modify cellulose fibers. If this modification is excessively performed, the flexibility of the fabric is reduced due to the formation of crosslinks, and therefore treatment with an amino-modified silicone softener is generally required. However, when softening agents such as amino-modified silicones are used in combination, they are hydrophobic, so the water absorption of the treated fabric is lowered, and when actually worn as clothing, the sweat absorption is poor and the feeling of comfort. There was a problem that it would be bad. On the other hand, if the cross-linking modification is not sufficiently performed, the present state is that it is not possible to provide the required level of form-stabilizing performance such as wrinkle resistance and shrinkage resistance.
[0003]
[Problems to be solved by the invention]
In view of such a background, the present invention intends to provide a cellulosic fiber-containing fabric having both shape stability performance such as wrinkle resistance and shrinkage resistance and water absorption.
[0004]
[Means for Solving the Problems]
In order to solve this problem, the present invention has the following configuration.
[0005]
That is, a fabric containing cellulosic fibers that have been crosslinked and modified, wherein the fabric has a crosslinking index defined by the following formula of 1 to 4, and a water absorption measured by the JIS L-1096 birec method is 50 mm or more. A cellulosic fiber-containing fabric characterized in that:
[0006]
Cross-linking index = (A−B)
A: Moisture absorption rate (%) of the cellulosic fiber after crosslinking modification in a temperature of 30 ° C. and a relative humidity of 90% RH atmosphere.
[0007]
B: Moisture absorption rate (%) of the cellulosic fiber after cross-linking modification under a temperature of 20 ° C. and a relative humidity of 65% RH atmosphere.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The cellulosic fiber-containing fabric referred to in the present invention is a fabric containing natural cellulose fibers such as cotton, hemp, and pulp, and regenerated cellulose fibers such as viscose rayon, and polyester such as polyethylene terephthalate and polybutylene terephthalate. Blended fibers, blended fibers such as polyamide fibers such as nylon 6 and nylon 66, polyolefin fibers such as polyethylene and polypropylene, protein fibers such as wool and silk, polyvinyl chloride fibers, vinylon fibers, acetate fibers, etc. Also included are those used in combination with weaving and knitting. In addition, from the aspect of the effect to be obtained, when mixed with other fibers, it is preferable that the cellulosic fibers contain 10 wt% or more by fiber weight.
[0009]
The cross-linking agent used for cross-linking modification reacts with hydroxyl groups in cellulose molecules constituting cellulosic fibers, particularly wrinkles during washing, and hydroxyl groups in the amorphous region causing shrinkage. A compound capable of forming a crosslink is preferably used. Specifically, formaldehyde, dimethylol ethylene urea, dimethylol triazone, dimethylol uron, dimethylol glyoxal monourene, dimethylol propylene urea, methoxylated or ethoxylated part or all of these methylol groups And the like, and the like, fiber-reactive resins, polycarboxylic acids, isocyanates and the like. Among these crosslinking agents, in order to perform the cross-linking modification of cellulosic fibers more efficiently, effectively, in the present invention, the need use the compounds represented by the following general formula [I].
[0010]
[Chemical 2]
Here, R 1 and R 2 are the same or different groups that are either —H, an alkyl group having 1 to 4 carbon atoms, or —CH 2 OR 7 . R 3 , R 4 , R 5 , and R 6 are the same or different groups that are either —H or —OR 8 . R 7 and R 8 are the same or different groups each being —H or an alkyl group having 1 to 4 carbon atoms . As a method for applying such a crosslinking agent to the cellulose fiber, general crosslinking means can be applied. Specifically, a method of applying the crosslinking agent in a gaseous state, a padding method, a dipping method, a spray method, a printing method. , coating, gravure process method, foam processing method, and the like, cross-linking agents in Naka is cellulose reactive resin, polycarboxylic acids, padding method in the case of such isocyanates are preferably used.
[0011]
Such a method of crosslinking modification of cellulose fibers by crosslinking agents generally are of crosslinkable modification method is applied, specifically, the above relative cellulosic fiber-containing fabric remains fabric帛crosslinking Examples include post-cure methods in which an agent is applied and sewed, followed by heat treatment, and pre-cure methods in which the above-described crosslinking agent is applied to the cellulose-based fiber-containing fabric as it is and the heat treatment is performed. It is not limited. The heat treatment temperature is preferably in the range of 80 to 220 ° C.
[0012]
In carrying out cross-linking modification of cellulosic fibers, it is also preferable to use a catalyst in combination for the purpose of accelerating the reaction of the cross-linking agent. Specifically, organic acids, organic amine salts, magnesium chloride, zinc nitrate, borofluoride are used. Metal salts such as zinc halide, magnesium nitrate, and zinc chloride can be used.
[0013]
The cellulosic fiber-containing fabric of the present invention contains cellulosic fibers crosslinked and modified by such a method, and the degree of modification is preferably within a range of a crosslinking index defined by the following formula of 1 to 4, more preferably. Must be in the range of 2 to 3.5.
[0014]
Cross-linking index = (A−B)
A: Moisture absorption rate (%) of the cellulosic fiber after crosslinking modification in a temperature of 30 ° C. and a relative humidity of 90% RH atmosphere.
[0015]
B: Moisture absorption rate (%) of the cellulosic fiber after cross-linking modification under a temperature of 20 ° C. and a relative humidity of 65% RH atmosphere.
[0016]
The crosslinking index is obtained by subtracting the value of the moisture absorption rate at a temperature of 20 ° C. and a relative humidity of 65% RH from the value of the moisture absorption rate at a temperature of 30 ° C. and a relative humidity of 90% RH. It is calculated and serves as an index for knowing how much the cellulosic fiber is crosslinked and modified. That is, this utilizes the fact that the hydroxyl group in the cellulose molecule is blocked by the cross-linking modification, resulting in a decrease in the value of moisture absorption. The smaller the index, the greater the degree of crosslinking modification, and the greater the index, the smaller the degree of crosslinking modification. Generally, it is about 4 to 5 for raw cotton and hemp.
[0017]
When the cross-linking index is less than 1, the cross-linking is excessively formed, the strength and flexibility of the fabric is lowered, and the shape stability is good, but it is not practical. When the strength and flexibility of the fabric are reduced, treatment with an amino-modified silicone softener is generally performed for the purpose of improving them. However, when a softener such as amino-modified silicone is used in combination, they are hydrophobic. Therefore, the water absorption of the treated fabric is lowered, and when it is actually worn as a garment, the sweat absorbency is poor and the feeling of comfort is poor. On the other hand, when the cross-linking index is larger than 4, the cellulose fiber is not sufficiently cross-linked and the required level of shape stability such as wrinkle resistance and shrinkage resistance cannot be imparted. In view of the balance between the strength, flexibility and shape stability of the fabric, the crosslinking index is more preferably in the range of 2 to 3.5.
[0018]
The cellulose fiber-containing fabric of the present invention has a water absorption of 50 mm or more as measured by JIS L-1096 birec method. If the water absorption is less than 50 mm, the clothing obtained by sewing such a fabric has poor sweat absorption and poor comfort.
[0019]
In the present invention, for the purpose of improving the flexibility of the fabric, it is also preferable to apply a silicone softener. However, when a fabric is treated with a commonly used silicone softener, particularly an amino-modified silicone softener mainly composed of an aminoalkyl group-containing polysiloxane, the flexibility of the treated fabric and the durability of the effect Although the properties are excellent, the treated fabric comes to exhibit water repellency, and is unsuitable for application to a cellulosic fiber-containing fabric having both shape stability performance such as wrinkle resistance and shrinkage resistance and water absorption.
[0020]
Accordingly, the silicone softener in the present invention is preferably one that gives a soft texture without hindering the water absorption of the fabric, and specifically, an organo group containing both an amino group and a polyoxyalkyl group in one molecule. The main component is preferably a polysiloxane and a polyethylene polyamine higher fatty acid amide compound containing at least one group capable of reacting with an amine or a hydroxyl group in the molecule.
[0021]
The organopolysiloxane is not particularly limited as long as it is an organopolysiloxane containing both an amino group and a polyoxyalkyl group in one molecule, that is, an aminopolyether-modified silicone. Those having 100,000 cst and amino equivalents in the range of 300-3000 are preferred. The amino group of the amino polyether-modified silicone is partially or completely blocked by a compound having reactivity with the amino group, an organic acid, an organic acid anhydride or chloride to prevent yellowing. May be.
[0022]
Further, as the polyethylene polyamine higher fatty acid type amide compound, polyethylene polyamine higher fatty acid amide, urea condensate of polyethylene polyamine higher fatty acid amide, imidazolinium salt of polyethylene polyamine higher fatty acid type amide part and dicarboxylic acid, cyclic acid anhydride, Examples thereof include a reaction product with diglycidyl ether, diisocyanate and the like.
[0023]
Examples of the polyethylenepolyamine that is a component of these include diethylenetriamine, triethylenetetramine, tetraethylenebentamine, and aminoethylethanolamine. Higher fatty acids are generally derived from natural fats and oils such as palm oil, beef tallow, rapeseed oil, rice bran oil and fish oil, but chemically synthesized higher fatty acids can also be used. Among these, higher fatty acids having an iodine value of 50 or less and 12 to 24 carbon atoms are preferable. Examples of the dicarboxylic acid and cyclic acid anhydride include maleic acid, maleic anhydride, fumaric acid, malic acid, succinic acid, succinic anhydride, tartaric acid, phthalic acid, and phthalic anhydride. Examples of the diglycidyl ether include ethylene glycol diglycidyl ether, propylene glycol diglycidyl ether, polyoxyalkylene glycol diglycidyl ether, neopentyl glycol diglycidyl ether, 1,6-hexanediol diglycidyl ether, and the like. Examples of the diisocyanate include aromatic diisocyanates such as tolylene diisocyanate, xylene diisocyanate and diphenylmethane diisocyanate, and aliphatic diisocyanates such as tetramethylene diisocyanate, hexamethylene diisocyanate and lysine diisocyanate.
[0024]
The molar ratio of the polyethylene polyamine and the higher fatty acid constituting the polyethylene polyamine higher fatty acid type amide compound is usually 1: 1.0 to 2.5, preferably 1: 1.2 to 1.8.
[0025]
The weight ratio of aminopolyether-modified silicone, which is the main component of such a silicone softener, and polyethylenepolyamine higher fatty acid amide is 1: 0.2 to 1.5, preferably 1: 0.3 to 1.0. When the polyethylene polyamine higher fatty acid amide is less than 0.2, sufficient flexibility cannot be obtained, and when it exceeds 1.5, the water absorption of the treated fabric is lowered, which is not preferable.
[0026]
It is preferable that the adhesion amount with respect to the fiber weight of such a silicone type softening agent is in the range of 0.06 to 1.0 wt%. When the adhesion amount is less than 0.06 wt%, it is difficult to impart sufficient flexibility and smoothness to the fabric, and when it is greater than 1.0 wt%, the flexibility and smoothness are improved. This causes defects such as eye misalignment.
[0027]
In the present invention, a hydrophilic resin, preferably a hydrophilic polyester resin, is also preferably applied for the purpose of improving the water absorption of the fabric. Among them, those having a polyalkylene glycol-polyester block copolymer as a main component are preferable.
[0028]
The polyalkylene glycol as used herein means one having a main chain of —C n H 2n O— (n = 2 to 4) in the molecule, specifically, polyethylene glycol, polypropylene glycol, or a block polymer thereof. Etc. The molecular weight of the polyalkylene glycol is preferably in the range of 300 to 40,000, more preferably 1000 to 10,000. When the molecular weight is less than 300, the adhesion durability to the fiber tends to be insufficient, and when the molecular weight exceeds 40,000, the dispersibility tends to decrease.
[0029]
Moreover, as polyester which carries out block copolymerization of this polyalkylene glycol, what consists of aromatic dicarboxylic acid and alkylene glycol is preferable. Examples of the aromatic dicarboxylic acid include terephthalic acid, a lower alkyl ester of terephthalic acid, isophthalic acid, and a lower alkyl ester of isophthalic acid. Examples of the alkylene glycol include ethylene glycol, propylene glycol, and butylene glycol.
[0030]
The adhesion amount of the hydrophilic polyester resin with respect to the fiber weight is preferably in the range of 0.03 to 1.0 wt%. When the adhesion amount is less than 0.03 wt%, the effect of applying the hydrophilic polyester resin is small. When the adhesion amount is greater than 1.0 wt%, the water absorption of the fabric is improved, but the cloth has a slimy feeling. Moreover, it also causes a decrease in dyeing fastness.
[0031]
The fiber product using the cellulosic fiber-containing fabric of the present invention is excellent in shape stability such as wrinkle resistance and shrinkage resistance, water absorption, dress shirt, school shirt for school children, uniform, women's clothing, sports clothing, It is suitable for such applications.
