発明の詳細な説明Detailed Description of the Invention

本発明はポリハロゲノピリミジン系化合物を架橋剤として用い、セルロース系繊維材料を架橋反応によって改質加工する事を特徴とする、セルロース系繊維材料の改質加工法である。
更に詳しくは本発明は、セルロース系繊維材料に抗ピリング性、着用快適性、風合良好性、形態安定性、高弾性などの機能性を付与するに当って、ポリハロゲノピリミジン、特にポリクロロピリミジンからなるピリミジン系化合物を架橋剤として用い、水中にアルカリ剤とセルロース系繊維材料を加え、必要に応じて乳化剤或いは分散剤を共存させて、アルカリ性で加熱反応処理することによってセルロース系繊維材料を改質加工する事を特徴とするセルロース系繊維材料の改質加工法である。
The present invention is a method for modifying a cellulosic fiber material, characterized in that a polyhalogenopyrimidine compound is used as a crosslinking agent and the cellulosic fiber material is modified by a crosslinking reaction.
More particularly, the present invention relates to polyhalogenopyrimidines, particularly polychloropyrimidines, in imparting functionalities such as anti-pilling properties, wearing comfort, good texture, shape stability, and high elasticity to cellulosic fiber materials. The cellulose fiber material is modified by adding an alkali agent and a cellulosic fiber material in water, and if necessary, coexisting an emulsifier or a dispersant, and subjecting it to an alkaline heat reaction treatment. It is a modification processing method of cellulosic fiber material characterized by quality processing.

近年、生活の質の向上と環境・安全・健康問題への関心の高まりに伴って、形状記憶繊維、難燃・防炎繊維、紫外線遮蔽繊維、防虫・防ダニ繊維、抗菌繊維、消臭繊維、高質感・高風合繊維、皮膚障害予防繊維等の機能性繊維が次々と開発されており、繊維業界の注目を集めている。一方、中国に席捲されつつある日本の繊維産業が生き残り、中国と共生する為には、繊維に付加価値をつけた機能性繊維の開発が不可欠と考えられ、そのような観点からも機能性繊維の開発と実用化は日本の繊維業界にとって極めて重要な課題となっている。
セルロース系繊維はソフトな肌触り感を有しており、吸水性も優れている天然繊維であることから肌着に用いられる事が多い。
中でも近年関心が高まりつつあるモダル等の高級再生セルロース系繊維はセルロース繊維本来の物性の他に、光沢感、強度或いは高弾性率、しなやかさ、温かさ、吸湿性等、優れた物性を有するため、おしゃれなアウターウエアやインナーとしてよく用いられるようになっている。
In recent years, with the improvement of quality of life and increasing interest in environmental, safety and health issues, shape memory fibers, flame retardant and flame retardant fibers, UV shielding fibers, insect and mite fibers, antibacterial fibers and deodorant fibers Functional fibers such as high-texture / high-quality fibers and skin damage prevention fibers have been developed one after another, attracting the attention of the textile industry. On the other hand, in order for the Japanese textile industry, which is being overwhelmed by China, to survive and coexist with China, it is considered indispensable to develop functional fibers with added value to the fibers. Development and practical application of this technology are extremely important issues for the Japanese textile industry.
Cellulosic fibers are often used for underwear because they are natural fibers that have a soft touch and are excellent in water absorption.
Among them, high-grade regenerated cellulosic fibers such as modals, which have been attracting increasing interest in recent years, have excellent physical properties such as glossiness, strength or high elastic modulus, flexibility, warmth, hygroscopicity, in addition to the original physical properties of cellulose fibers. It is often used as a fashionable outerwear and inner.

しかしながらセルロース系繊維の欠点は、洗濯を繰返す事で、毛羽立ちが生じ、光沢が失われ、肌触り等の風合が劣化して次第に硬くなる事である。その結果、ピリングを生じて見映えも悪くなるし、肌触りも益々悪くなる。
例えば特開平11−152681号公報には、リヨセルのフィブリル化を問題視して、その解決法として、ジクロルトリアジン系化合物を用いて改善する加工法が提案されている。
この場合使用される架橋薬剤は、ジクロルトリアジン系薬剤であるが、この架橋薬剤には幾つかの欠点がある。最も問題なのはこれらの化合物が不安定である点である。例えば、この特許の請求項−3に記載されている(16)なる化合物は不安定で、この10%水溶液を冷蔵庫内5℃で保管しておくと1〜3ヶ月間で相当量分解が進んでしまい使い物にならなくなってしまう。不安定であると言う事は加工効果にも良くない影響を及ぼす可能性を示唆している。即ち加工工程中、繊維と反応する前に薬剤自身の加水分解が進行して架橋能力を失ってしまう割合が高くなる可能性が大きい。
その結果、品質の再現性や充分な加工効果が期待できないと言う問題がある。
同じ様な特許として特許第3366000号公報、特開2003−049362号公報等が公開されている。
However, the disadvantages of cellulosic fibers are that repeated washing results in fuzzing, loss of luster, and deterioration of the texture such as the touch and gradually becomes harder. As a result, pilling occurs and the appearance becomes worse, and the touch becomes worse.
For example, Japanese Patent Application Laid-Open No. 11-152681 proposes a processing method using dichlorotriazine-based compounds as a solution to the fibrillation of lyocell as a problem.
The crosslinking agent used in this case is a dichlorotriazine-based agent, but this crosslinking agent has several disadvantages. The most problematic is that these compounds are unstable. For example, the compound (16) described in claim 3 of this patent is unstable, and if this 10% aqueous solution is stored in a refrigerator at 5 ° C., a considerable amount of decomposition proceeds in 1 to 3 months. It will not be useful. The fact that it is unstable suggests that the processing effect may be adversely affected. In other words, during the processing step, there is a high possibility that the rate at which the hydrolysis of the drug itself proceeds and loses the crosslinking ability before reacting with the fiber becomes high.
As a result, there is a problem that quality reproducibility and sufficient processing effect cannot be expected.
As similar patents, Japanese Patent No. 3366000, Japanese Patent Application Laid-Open No. 2003-049362, and the like are disclosed.

特開平8−158264号公報や特開2001−64874号公報には樹脂加工による風合改善の特許が公開されているが、本発明の様に分子単位で架橋反応する場合と違い、繊維表面に樹脂皮膜を作ると言う考え方であって、合成樹脂類は繊維の風合や吸湿性を損なうのが一般的であり、本来のセルロース繊維の物性に悪影響が現れる可能性が大きい。  In JP-A-8-158264 and JP-A-2001-64874, patents for improving the texture by resin processing are disclosed, but unlike the case of crosslinking reaction in molecular units as in the present invention, the surface of the fiber is changed. It is an idea of making a resin film, and synthetic resins generally impair the texture and hygroscopicity of the fiber, and there is a great possibility that the physical properties of the original cellulose fiber will be adversely affected.

発明が解決しようとする課題Problems to be solved by the invention

前記した様に、風合や毛羽立ちを改善する方法が多くの公知文献に記載されているが、加工効果や効果の耐久性に問題を抱えており、架橋薬剤が不安定で加工製品の品質に再現性が得がたい等の問題点に着目して、我々は経済性と環境問題適応性に優れ、抗ピリング性、風合や光沢の維持、形態安定性などの機能性付与効果も大きく、繰り返し洗濯に対する耐久性にも優れた実用的価値の高い架橋薬剤のスクリーニングと加工方法の実用化研究を行った。  As described above, methods for improving the texture and fluff are described in many known literatures, but there are problems with the processing effect and durability of the effect, the crosslinking agent is unstable and the quality of the processed product is increased. Focusing on problems such as inability to obtain reproducibility, we have excellent economic efficiency and adaptability to environmental problems, anti-pilling property, maintenance of texture and gloss, and functional effects such as form stability, and repeated washing Screening of cross-linking agents with high practical value and excellent practical durability of the materials and research on their practical application.
