一、双边型复合纤维，这种纤维是大棚无纺布中 主要的构成成分。
1. Bilateral composite fibers, which are the main components of greenhouse non-woven fabrics.
二、皮芯型复合纤维，仅次于 种纤维存在于这些保温材料中，并非是所有的都含有。
2. Sheath-core composite fibers, second only to seed fibers, exist in these insulation materials, not all of them contain.
三、分散性复合纤维，这些成分在大棚无纺布中并不固定，根据不同的产品具有不同的含量。

3. Dispersible composite fibers. These components are not fixed in non-woven fabrics of greenhouse. They have different contents according to different products.www.baodingjiaju.com.cnwww.hupomuju.com.cnzhuzaojg.37ix.com.cn

四、多芯型复合纤维，在大棚无纺布的生产和成分中，这种多芯型的材料是必不可少的。
4. Multi-core composite fibers are essential in the production and composition of greenhouse non-woven fabrics.
