Frost protection fabric is a material used in agriculture to keep crops warm and protected from cold. It is a non-woven fabric. As an important tool for resisting low temperatures and protecting plants in agriculture and greening projects, its service life directly affects the cost of use and the effectiveness of protection. If the correct method can be mastered to extend its service life, it can not only save expenses, but also continue to protect plants. Here, Liansheng will introduce to you the factors that affect the lifespan of cold proof fabrics and the measures we should take.
Reasons for the aging of cold proof fabric
Like other chemical products, under the action of light and heat, the fabric surface will also age. The reason for the aging of cold resistant fabrics is mainly the result of the combined effect of internal and external factors. Internal factors include the chemical composition, molecular weight distribution, and organizational structure of the material itself. External factors usually refer to the influencing factors in the external environment in which the material is located, including:
(1) Physical factors such as mechanical stress, heat, water, light, etc.
(2) Chemical factors, such as corrosive gases or liquids, etc.
(3) Biological factors such as microorganisms, bacteria, molds, insects, etc.
Among them, photo aging and photo degradation are one of the most important problems encountered in the practical application of cold proof fabrics.
Choosing the right model and adapting to the scene is the foundation
The demand for cold proof fabric varies in different scenarios, and choosing the appropriate model is the first step in extending its service life. In agricultural cultivation, the cold proof cloth used to cover low vegetables can be selected from lightweight and breathable models; For fruit trees and large seedlings used for cold protection, it is necessary to choose styles with stronger toughness and better tear resistance. In the slope protection of greening projects, if it is necessary to balance cold and wind resistance, products with high density and outstanding wear resistance should be selected. If the model does not match the usage scenario, such as covering areas with strong wind with lightweight and cold resistant cloth, it is easy to break due to repeated pulling, greatly shortening the service life.
Standardized installation to reduce physical damage
Improper operation during installation is a common cause of premature damage to the insulation fabric. When installing, the first thing to ensure is that the ground in the coverage area is flat, and sharp stones, branches, and other debris should be removed to avoid these objects forming friction points under the cold cloth, causing local wear. When fixing the cold proof fabric, excessive pulling should be avoided, and a certain amount of expansion and contraction space should be reserved to prevent excessive tension caused by temperature changes or wind force, which may cause the fabric to tear. When using fixed clips or heavy objects to fix the edges, pay attention to moderate force to avoid clamping too tightly and causing damage to the fabric edges. For scenarios that require the construction of supporting structures, soft cloth should be used to wrap the edges and corners of the support to prevent the cold cloth from being scratched due to long-term contact with sharp areas.
Daily maintenance, timely handling of minor issues
Careful maintenance in daily use can effectively prevent minor damage from expanding and extend the service life of cold proof fabrics. Regularly check the condition of the cold proof cloth, and if small areas of damage are found, they should be repaired promptly with specialized tape. For situations where the tear is small, the damaged area can be aligned directly and covered with waterproof and wear-resistant specialized tape; If the damaged area is large, a piece of fabric of the same material can be cut as a patch and fixed at the damaged area with needle or tape. After encountering rainy and snowy weather, the snow and accumulated water on the cold proof cloth should be cleaned up in a timely manner to avoid excessive pressure of snow on the cold proof cloth, or prolonged soaking in water that may cause the cloth to mold. In addition, when carrying out field operations or greening maintenance, it is important to avoid direct contact between agricultural tools, equipment, and cold proof cloth to prevent scratching and damage.
Reasonably store and do a good job of storage protection
Proper storage during non use seasons is crucial for the lifespan of cold proof fabrics. Before storage, the cold proof cloth should be thoroughly cleaned to remove any dirt, weeds, and stains on the surface, in order to prevent these substances from corroding the fabric during storage. After cleaning, place the cold proof fabric in a ventilated and cool place to dry. Do not expose it to direct sunlight to prevent the fabric from aging and becoming brittle due to excessive exposure to ultraviolet rays. After drying, the cold proof cloth should be folded neatly to avoid long-term stress deformation caused by random stacking. When storing, choose a dry, ventilated, and dark environment, away from sources of fire and corrosive substances. It can be placed in a dedicated storage bag or wooden box, and insect proof materials such as camphor balls can be placed around it to prevent insect infestation.
Scientific use to avoid excessive wear and tear
According to different usage needs and environmental conditions, scientifically arrange the usage time of cold proof cloth to avoid unnecessary wear and tear. When the temperature rises and there is no need for cold protection, the cold cloth should be promptly retracted to avoid prolonged exposure to sunlight or wind and rain, and to reduce the rate of natural aging. For reusable cold proof fabrics, do not use them in scenarios that exceed their load-bearing capacity, such as covering heavy objects with ordinary cold proof fabrics or forcibly using them in harsh weather conditions, as these will accelerate the damage of the cold proof fabric. At the same time, avoid using cold proof fabrics for unexpected purposes, such as sunshade fabrics, rainproof fabrics, etc. Different functional fabrics have different designs, and overuse can lead to a rapid decline in their performance.
By using the above methods, the service life of the cold proof cloth can be significantly extended, allowing it to continue to provide good protective effects in multiple uses. Whether it is agricultural planting or greening projects, doing a good job in the maintenance of cold proof fabrics can not only reduce costs, but also improve the efficiency of resource utilization, providing more sustainable protection for plants.
