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.
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.
External factors usually refer to the influencing factors in the external environment of materials, including:
(1) physical factors, such as mechanical stress, heat, water, light, etc
(2) Chemical factors, such as corrosive gases or liquids
(3) biological factors, such as microorganisms, bacteria, molds, insects, etc.
