无防布具有良好的微气候调节功能，可隔热、保温，既可达到改善环境和生长条件的作用，又可起到保护作用，无纺布在国内外农业生产领域被广泛用作农用覆盖材料、植物生长基质材料、温室大棚材料及农田水土保护用材料，并取得了显著的效果，其虽然质量较轻，但拥有良好的力学性能，其韧性和强度都较高，通常可重复多次使用，这无疑大大减少了无纺布的使用量，加上其容易回收的特点使其更符合环保的要求。
The non-woven fabric has a good microclimate regulation function, which can insulate and heat preservation. It can not only improve the environment and growth conditions, but also play a protective role. The non-woven fabric is widely used as agricultural covering materials, plant growth matrix materials, greenhouse materials and farmland soil and water conservation materials in the domestic and foreign agricultural production fields, and has achieved remarkable results, although its quality is relatively high Light, but with good mechanical properties, its toughness and strength are high, usually can be reused many times, which undoubtedly greatly reduces the use of non-woven fabric, coupled with its easy to recycle characteristics, making it more in line with the requirements of environmental protection.
如同其他化工材料一样，在光州苗木 保定通风管道 丝网立柱模具 尼龙输送带 保定防水 保定空压机 高碑店养老院热作用的条件下，防寒布也会出现老化，防寒布发生老化的原因，主要是内外因素综合作用的结果。内因包括材料本身的化学组成、分子量分布、组织结构等因素。
Like other chemical materials, under the condition of light and heat, the cold proof cloth will also age. The main reason for the aging of cold proof cloth is the comprehensive effect of internal and external factors. Internal factors include chemical composition, molecular weight distribution, structure and other factors.
而外因通常是指材料所处的外界环境中的影响因素，包括：
External factors usually refer to the influencing factors in the external environment of materials, including:
