防寒布的定义：
Definition of cold resistant fabric:
防寒布是一种用来防止果树果实过冬时被冻坏的一种布，多为透光或者半透光的新型材料塑料膜。防寒布具有良好的气候调节功能，可以隔热、保温、既可以改善农作物生长环境和生长条件，又可以对农作物起到保护功能，防寒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，并取得了很好的效果。像是果农种植的柑橘、枇杷、沙糖桔、火龙果、百香果等使用防寒布都能起到很好的保护作用。
Cold resistant cloth is a new type of material plastic film used to prevent fruit trees from freezing and damaging during winter. It is mostly transparent or semi transparent. Cold resistant fabrics have good climate regulation functions, such as insulation and heat preservation. They can not only improve the growth environment and conditions of crops, but also provide protection for crops. Cold resistant fabrics are widely used in agricultural production fields both domestically and internationally as agricultural cover materials, plant growth substrate materials, greenhouse materials, and materials for soil and water protection in farmland, and have achieved good results. The use of cold resistant cloth can provide good protection for citrus, loquat, sugar orange, dragon fruit, passion fruit and other fruits planted by fruit farmers.
防寒布覆盖
Cold resistant cloth covering
防寒布也叫做防冻布，是无纺布的一种。无纺布又称不织布、针刺棉、针刺无纺布等，是由定向的或随机的纤维而构成。因具有布的外观和某些性能而称其为布。
Cold resistant fabric, also known as antifreeze fabric, is a type of non-woven fabric. Non woven fabric, also known as non-woven fabric, needle punched cotton, needle punched non-woven fabric, etc., is composed of oriented or random fibers. It is called cloth due to its appearance and certain properties.
无纺布具有防潮、透气、柔韧、质轻、不助燃、容易分解、无毒无刺激性、色彩丰富、价格低廉、可循环再用等特点。如多采用聚丙烯（pp材质）粒料为原料，经高温熔融、喷丝、铺纲、热压卷取连续一步法生产而成。
Non woven fabrics have the characteristics of moisture resistance, breathability, flexibility, lightweight, non combustible, easy decomposition, non-toxic and non irritating, rich colors, low price, and recyclability. If polypropylene (PP material) pellets are commonly used as raw materials, they are produced through a one-step process of high-temperature melting, spinning, laying, and hot pressing and coiling.
