201202498 六、發明說明： 【發明所屬之技術領域】 本發明係有關於一種纖維材料，特別有關於一種具有 吸收紅外線功能的纖維材料。 【先前技術】 一般的天然或合成纖維要達到較佳的保暖效果，通常 需使用經緯密度高的織物或增加織物的厚度，但是這些方 式會使得紡織成品的透氣性變差且重量增加。 另外，在紡織成品中還可以使用動物羽絨作為充填 物，或使用人造的中空或多孔性纖維來製成紡織成品，以 達到保暖且輕量化的效果。然而，此類紡織成品具有高蓬 鬆性，會造成使用者活動的不便。 因此，業界亟需一種纖維材料，其可以使得纖維及其 製成的紡織品具有保暖性，並同時具有輕量化以及避免紡 織成品過度蓬鬆的特性，以克服上述缺點。 目前已有人利用碳化锆粉體添加分散於纖維内的做法 來製備紡織品，其吸收紅外線的性能優異（紅外線能量可轉 換為熱能，導致紡織品溫度上升，達到保暖效果），但是因 為其紡織品是深黑色且價格非常昂貴，導致應用受到了很 大的限制。因此，研發淺色系和生產成本較低的吸收紅外 線功能紡織品，是目前的重點方向。 氧化鋅是一種半導體材料，其禁帶寬度(energy gap)於 室溫下為3.37eV，隨著氧化鋅粉體的尺寸減小，其禁帶寬 度會逐漸增加，為了提升其電氣或光學性質，通常摻雜第 IIIA至VA族的元素。氧化鋅或摻雜第IIIA至VA族元素 201202498 的氧化鋅通常應用在與半導體產業相關的產業上，例如導 電材料、壓電材料、氣體探測器或太陽能電池等。 【發明内容】 本發明之實施例提供一種具有吸收紅外線功能的纖 維，此纖維包括纖維主體，以及具有吸收紅外線功能的粉 體，添加分散於纖維主體的内部。 此外，本發明之實施例還提供一種具有吸收紅外線功 能的紡織品，其包括如上所述之具有吸收紅外線功能的纖 維。 另外，本發明之實施例還提供一種具有吸收紅外線功 能之纖維的製造方法，該方法包括：提供具有吸收紅外線 功能的粉體，提供至少一單體與此粉體摻合，將單體聚合， 形成至少一高分子與此粉體摻合的複合材料，以及將複合 材料以紡絲工程加工，形成具有吸收紅外線功能之纖維， 其中粉體添加分散於纖維的内部。 在另一實施例中，提供一種具有吸收紅外線功能之纖 維的製造方法，該方法包括：提供具有吸收紅外線功能的 粉體，提供至少一高分子與此粉體混摻，形成高分子與此 粉體混摻的複合材料，以及將複合材料以紡絲工程加工， 形成具有吸收紅外線功能之纖維，其中粉體添加分散於纖 維的内部。 添加本發明之具有吸收紅外線功能的粉體所製成的紡 織品，其顏色改變相對於未添加粉體的紡織品而言，平均 可見光反射率差異只有2%左右。此性能遠優於添加碳化锆 粉體的紡織品（具有吸收紅外線功能），其顏色改變非常明 201202498 顯，平均可見光反射率差異可以達到40%以上。 懂，月之上述目的、特徵、及優點能更明顯易 【實施方ir圖式’作詳細說明如下： 維主具有吸收紅親功㈣粉體添加分散於纖 ，·’収、口p使传纖維具有吸收紅外線的功能，並使得 :纖的纺織品也具有吸收紅外線輸並:: 織吸收紅外線及保暖的功效’並同時保‘紡 …口：：匕的優點以及避免紡織品過度蓬鬆的缺點。 以是摻雜：二：：知例中’具有吸收紅外線功能的粉體可 之金屬種以上第ΠΙΑ族至第va族的金屬元素 物粉體’或者為前述摻雜有第ΙΠΑ族至第VA 矢、·屬元素之金屬氧化物粉 體的組合。 ' 例中，具有吸收紅外線功能的粉體可為摻雜 :二：:(Α1)或前述元素之組合的氧化鋅(ΖηΟ)粉體，或 者摻雜不同元素的氧化鋅粉體之組合，此具有摻雜 有吸收能Γ鋅，體對於波長約在78Gnm以上的紅外線具 氧化鋅粉體的粒徑可介於約10 nm至200nm =氣=為、小於1()0nm。在一實施例中，於具有摻雜元 元辛-重中’摻雜元素的重量百分比約佔鋅和摻雜 兀素…重里的0·α20重量百分比(wt%)。 =刚内摻雜鎵(Ga)，Ai)的方法可為： 的氣化物或者硫酸鹽與摻雜元素（包括鎵、銘） 。.祖製：混合溶液，濃“ 〃疋素的添加莫耳量為鋅和摻雜元素 201202498 總莫耳量的 0.1mol%~10.0mol%.

Description of the Invention: [Technical Field] The present invention relates to a fiber material, and more particularly to a fiber material having an infrared absorbing function. [Prior Art] In order to achieve a better warming effect of a natural or synthetic fiber, it is usually necessary to use a fabric having a high warp density or to increase the thickness of the fabric, but these methods may deteriorate the gas permeability of the finished textile product and increase the weight. In addition, animal down can be used as a filling in the finished textile product, or artificial hollow or porous fiber can be used to make the finished textile product to achieve warmth and light weight. However, such textile products are highly velvety and cause inconvenience to the user's activities. Accordingly, there is a need in the art for a fibrous material that can provide thermal insulation to the fibers and the textiles they make, while at the same time having a lightweight and avoiding excessive fluffy properties of the finished textile product to overcome the above disadvantages. At present, people have used zirconia powder to add and disperse in the fiber to prepare textiles, which have excellent infrared absorption performance (infrared energy can be converted into heat energy, which causes the temperature of the textile to rise to achieve warmth), but because the textile is dark black. And the price is very expensive, which leads to a very limited application. Therefore, the development of light-colored systems and infrared-absorbing functional textiles with lower production costs are the current focus. Zinc oxide is a semiconductor material with an energy gap of 3.37 eV at room temperature. As the size of the zinc oxide powder decreases, the band gap increases gradually. To enhance its electrical or optical properties, Elements of Groups IIIA through VA are typically doped. Zinc Oxide or Zinc Oxide No. IIIA to VA Element 201202498 is commonly used in industries related to the semiconductor industry, such as conductive materials, piezoelectric materials, gas detectors or solar cells.
