菠萝叶纤维的开发与应用现状及前景

菠萝叶中含有较为丰富的纤维（菠萝麻），是一种优质的天然纺织原料，可纯纺，也可混纺。从新鲜菠萝叶中可提取1．5％的干纤维。一般每公顷菠萝地可产60～90t鲜叶片，能提取900～1350kg干纤维。开发利用菠萝叶纤维，实现果、叶兼用，能大幅度提高菠萝种植业的经济效益，形成热带和亚热带地区新的产业和经济增长点。同时，菠萝叶纤维作为可再生天然纤维对于我国纺织原料的可持续发展具有重要的意义。

The Development and Application of Pineapple Leaf Fiber: Present & Future

Pineapple leaves are rich in fiber, which is called pineapple fiber. It is a high-quality natural textile fiber for spinning both pure and blended yarn. 1.5% dry fiber can be extracted from fresh pineapple leaf. Generally, one hectare of pineapple growing land can yield 60-90 tons of pineapple leaf, which means 900-1,350 kg of dry fiber can be obtained. Making good use of pineapple leaf to realize multiple utilization of pineapple plant can help pineapple growers significantly increase their economic benefit and help the tropical and subtropical areas develop a new industry and a new economic growth point. Furthermore, as a regenerable natural fiber, pineapple leaf fiber is expected to make great contribution to the sustainable development of textile raw materials in China.
