Description
本発明は、織物の技術分野に関し、具体的には、温度調節機能を有する不織布、その製造方法及び使用に関する。 The present invention relates to the technical field of woven fabrics, and specifically to non-woven fabrics having a temperature control function, a method for producing the same, and use thereof.
織物市場全体の需要が増加するに伴い、織物の重要な構成材料である不織布に対する需要も増加しており、紡績生地は、徐々に知能化、機能化へ発展しており、不織布は、配向繊維又はランダム繊維から構成され、耐湿性、通気性、柔軟性、靭性、軽量、低価格、リサイクル性などの特徴を有するので、広く使用されている。織物市場の発展に伴い、織物の分野において不織布に対して求められる要求も高まっている。不織布には、通気性、柔軟性、抗菌性などの特性が必要であるだけでなく、特殊な環境では、一定の温度調節機能も必要であり、例えば、暑い夏に、織物に使用される不織布原料には、ユーザの快適さを向上させるために、一定の温度調節機能が求められる。 As the demand for the entire textile market increases, so does the demand for non-woven fabrics, which are important constituent materials of textiles, and spun fabrics are gradually becoming more intelligent and functional. Nonwoven fabrics are oriented fibers. Alternatively, it is widely used because it is composed of random fibers and has features such as moisture resistance, breathability, flexibility, toughness, light weight, low price, and recyclability. With the development of the textile market, the demand for non-woven fabrics in the field of textiles is increasing. Non-woven fabrics need not only properties such as breathability, flexibility and antibacterial properties, but also a certain temperature control function in special environments, for example, non-woven fabrics used for textiles in hot summer. The raw material is required to have a certain temperature control function in order to improve the comfort of the user.
温度調節機能を有する織物材料を得るために、従来技術では、相変化材料を加えることで実現されている。相変化材料とは、温度を変えずに、物質の状態を変化させることで潜熱を提供する物質をいう。物理的特性が変化するプロセスは相変化プロセスと呼ばれ、この時点で、相変化材料は、大量の潜熱を吸収又は放出する。相変化材料は、その相変化プロセスによって、固−固相変化、固−液相変化、固−気相変化、及び液−気相変化に分けることができ、相変化プロセス中に、ガスの発生により相変化材料の体積が大きく変化するため、相変化プロセス中に、固−気相変化材料及び液−気相変化材料は、漏れやすく、パッケージに対する要求が高い。パラフィンは、一般的に使用されている相変化材料であるが、相変化材料として、パラフィンは、熱伝導率が低く、固−液相変化の場合は漏れやすいなどの欠点がある In order to obtain a woven material having a temperature control function, in the prior art, it is realized by adding a phase change material. A phase-changing material is a substance that provides latent heat by changing the state of the substance without changing the temperature. The process of changing physical properties is called the phase change process, at which point the phase change material absorbs or releases large amounts of latent heat. The phase change material can be divided into solid-solid phase change, solid-liquid phase change, solid-gas phase change, and liquid-gas phase change according to the phase change process, and gas is generated during the phase change process. Due to the large change in volume of the phase change material, the solid-gas phase change material and the liquid-gas phase change material are liable to leak during the phase change process, and the demand for the package is high. Paraffin is a commonly used phase change material, but as a phase change material, paraffin has drawbacks such as low thermal conductivity and easy leakage in the case of solid-liquid phase change.
従来技術による織物材料でも、相変化材料を使用して温度調節機能を付与する方法があるが、通常、織物材料の層間に相変化材料をコーティングすることにより、又は溶液紡糸により実施される。コーティング方式の場合は、耐洗濯性が悪いという問題があり、溶液紡糸の場合は、溶媒が必要であるので、溶媒残留の問題がある。溶融紡糸法にも、相変化材料の損失率が高く、均一に吐出できないなどの技術的課題がある。さらに、単一の高分子材料を相変化材料と複合する場合は、柔軟性が不十分であったり、通気性が悪かったりするなどの問題がある。 Even in the woven fabric material according to the prior art, there is a method of imparting a temperature control function by using the phase change material, but it is usually carried out by coating the phase change material between the layers of the woven material or by solution spinning. In the case of the coating method, there is a problem that the washing resistance is poor, and in the case of solution spinning, there is a problem of solvent residue because a solvent is required. The melt spinning method also has technical problems such as a high loss rate of the phase change material and the inability to uniformly discharge the material. Further, when a single polymer material is combined with a phase change material, there are problems such as insufficient flexibility and poor air permeability.
上記技術的課題を解決するために、本発明は、２種類の基材と１種類の相変化材料を用いて構成されるスキン・コア構造の温度調節機能を有する不織布を提供し、前記温度調節機能を有する不織布は、スキン・コア構造であり、スキン層構造は、相変化材料とＰＥを含む複合材料から構成され、コア層材料は、ＰＰから構成され、コア層材料とスキン層材料の収縮率が異なるため、温度調節機能を有する不織布に良好な柔軟性を付与し、相変化材料であるマイクロカプセルで包まれたパラフィンとＰＥから構成されるスキン層材料は、温度調節材料に良好な温度調節機能を付与する。 In order to solve the above technical problems, the present invention provides a non-woven fabric having a temperature control function of a skin core structure composed of two types of base materials and one type of phase change material, and the temperature control is performed. The non-woven fabric having a function has a skin core structure, the skin layer structure is composed of a composite material containing a phase change material and PE, the core layer material is composed of PP, and the core layer material and the skin layer material are shrunk. Due to the different rates, the non-woven fabric with temperature control function is given good flexibility, and the skin layer material composed of paraffin and PE wrapped in microcapsules, which is a phase change material, has a good temperature for the temperature control material. Gives an adjustment function.

本発明では、スキン・コア構造の不織布を製造するとき、異なる原料が使用され、スキン層材料に相変化材料を加える必要があるため、加工中にさまざまな加工特性を考慮する必要がある。本発明者らは、研究したところ、スパンボンド法を用いて単一の原料を用いて不織布を製造するプロセスで、ＰＰの紡糸温度は通常２３０−２４０℃であり、ＰＥの紡糸温度は２３５−２５０℃である一方、スキン・コア構造の繊維を製造するプロセスで、特に、スキン層材料に相変化材料としてマイクロカプセルで包まれたパラフィンを加える必要がある場合に、紡糸温度が高すぎると、相変化材料のエンタルピーの過大の損失をもたらす。本発明によるスキン層材料の溶融紡糸の温度が２０５−２１５℃である場合に、相変化材料であるマイクロカプセルで包まれたパラフィンのエンタルピー損失率は１０％よりも低く、スムーズな紡糸を確保することができ、スキン・コア構造繊維の柔軟性及びウェブ形成性を確保するために、本発明は、熱カレンダー・粘着がスキン層材料ＰＥの溶融温度より低い温度で行われ、スキンとコアの２種類の組成の融点、熱伝導率、結晶構造及び結晶化速度のいずれも異なり、ＰＥは、分子鎖が規則的であり、最小のエネルギーで最も安定した鋸歯状をもって格子に組み込むことができ、非常に結晶化しやすく、ＰＰは、分子鎖がらせん構造であり、配列が規則的であり、結晶化しやすいが、ＰＥよりも結晶性が低く、紡糸プロセス中、高速紡糸とその後の低温熱カレンダー・粘着に温度差が生じ、特定の圧力と熱カレンダー・粘着の速度でコア層ＰＰの結晶化が促進され、コア材とスキン層材料の結晶化の差が低下し、それにより良好なウェブ形成性が確保され、冷却中のコア層とスキン層の収縮率が異なるため、材料の柔軟性及び嵩高性も確保できる。 In the present invention, when producing a non-woven fabric having a skin core structure, different raw materials are used and it is necessary to add a phase change material to the skin layer material, so that various processing characteristics need to be taken into consideration during processing. The present inventors have studied that in the process of producing a non-woven fabric using a single raw material using the spunbond method, the spinning temperature of PP is usually 230-240 ° C, and the spinning temperature of PE is 235-. While at 250 ° C., if the spinning temperature is too high, especially in the process of producing fibers with a skin core structure, especially when it is necessary to add microcapsulated paraffin as a phase change material to the skin layer material, It results in an excessive loss of enthalpy of the phase change material. When the temperature of melt spinning of the skin layer material according to the present invention is 205-215 ° C., the enthalpy loss rate of the paraffin wrapped in the microcapsules which are the phase change materials is lower than 10%, and smooth spinning is ensured. In order to ensure the flexibility and web-forming properties of the skin-core structural fibers, the present invention allows the thermal calendar / adhesion to be performed at a temperature lower than the melting temperature of the skin layer material PE, and the skin and core 2 With different compositions, melting point, thermal conductivity, crystal structure and crystallization rate, PE has a regular molecular chain and can be incorporated into the lattice with the least energy and the most stable serrations. Easy to crystallize, PP has a spiral structure in the molecular chain, has a regular arrangement, and is easy to crystallize, but it is less crystalline than PE, and during the spinning process, high-speed spinning and subsequent low-temperature thermal calendar / adhesion Causes a temperature difference in the core layer PP, which promotes crystallization of the core layer PP at a specific pressure and thermal calendar / adhesion rate, reducing the difference in crystallization between the core material and the skin layer material, which results in good web formation. Since the shrinkage ratios of the core layer and the skin layer during cooling are different, the flexibility and bulkiness of the material can be ensured.
