What is cold cloth and what is the function of cold cloth?

Cold-proof cloth is also called anti-freeze cloth, which is a kind of non-woven fabric. Non-woven fabric (English name: NonWovenFabric or Nonwovencloth), also known as non-woven fabric, is composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabric has the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low price, and recyclable. For example, polypropylene (PP material) pellets are mostly used as raw materials, which are produced by continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing. Definition of cold-proof cloth: cold-proof cloth is a kind of cloth used to prevent fruit trees from being frosted during the winter. Most of them are transparent or semi-transparent new material plastic film. Cold cloth has a good climate regulation function, can heat and keep warm, not only can improve the growth environment and growth conditions of crops, but also can protect the crops. Cold cloth is widely used as agricultural covering material in the field of agricultural production at home and abroad. Plant growth substrate materials, greenhouse materials and farmland soil and water protection materials, and have achieved good results. For example, the citrus, loquat, sugar tangerine, dragon fruit, passion fruit grown by fruit growers can be protected by cold cloth. Classification of cold-proof cloth: There are many varieties of cold-proof cloth, including greening cold-proof cloth, agricultural cold-proof cloth, tree cold-proof cloth, citrus cold-proof cloth, fruit tree cold-proof cloth, garden cold-proof cloth, and printed cold-proof cloth. . . . . . Features of cold-proof cloth: cold-proof non-woven fabric is a new generation of environmentally friendly materials, which has the advantages of good strength, breathable and waterproof, environmental protection, flexibility, non-toxic and tasteless, and low price. It is waterproof, breathable, flexible, non-combustible, non-toxic, non-irritating, and rich in color. If the cold-proof cloth is naturally decomposed outside, its longest life is only 90 days. It will decompose within 5 years when placed indoors. It is non-toxic, odorless, and has no leftover substances when burned, so it does not pollute the environment, so environmental protection comes from this . The specifications of the cold-proof cloth: the specifications of the cold-proof cloth are 100 meters/rolls of 200 meters/rolls of cold-proof non-woven fabrics. The main component is pp (polypropylene). The widths of the cold-proof cloth are 2.4 meters, 3.2 meters, 4.8 meters, 6.4 meters, and other widths. The function of cold-proof cloth can be customized: 1. Cold-proof and heat preservation: increase the temperature in the shed (the temperature difference between the inside and outside of the shed can reach 3-5 degrees) to prevent low temperature and frost damage. 2. Breathable: Prevent sun fruit, fruit shrinkage and flower bud degradation caused by high temperature in the film, and improve citrus. Sugar Tangerine fruit quality and fruit yield. 3. The cold-proof cloth is simple and convenient to cover, no scaffolding is required, and it can be directly covered on the fruit without harm to the tree. Use a rope to fix the bottom or nail the surroundings. 4. Reduce the input cost. The cost of ordinary plastic film is 800 yuan per mu, the cost of shelf is about 2,000 yuan per mu, and the cost of cold-proof cloth is 1300 yuan per mu. There is no need to set up a shelf. Under normal service life, it can be used 3 times. Save manpower and material resources. 5. Breathable: Prevent sun fruit, fruit shrinkage and flower bud degradation caused by high temperature in the film, and improve citrus. Sugar Tangerine fruit quality and fruit yield. 6. Improve the appearance of citrus: the light transmittance is as high as 85%, and the sunlight is diffusely reflected after the sunlight passes through. The fruit is bright and uniform in color and looks good. 7. Reduce the shrinkage of citrus and sugar tangerines in the mature period, increase the sugar content and moisture, increase the taste, and increase the price of the fruit. 8. High utilization rate, can be used repeatedly for 3 years (the specific use time is related to the local ultraviolet intensity) 9. Moisturizing, maintaining soil moisture, can improve the soil micro-environment, and increase the yield by 13%. 10. Waterproof, old farmers wish that the waterproof performance of cold-proof cloth is very good to protect crops from being affected by freezing rain. The purpose of the cold-proof cloth: 1. It protects the newly planted seedlings from the winter, and is suitable for windshield, hedges, color blocks and other plants. 2. Use of bedding on exposed construction sites (to prevent dust), highways and other slope protection. 3. It is used for soil ball wrapping and mulching when transplanting tree and flowering shrubs. The advantages of the old farmer's wish for the cold-proof cloth: First, strong pulling force. The old farmer hopes that the cold-proof cloth can make the tensile force in all directions basically consistent and better tensile effect by adjusting the structure of the warp and weft, the uniformity and quantity of the silk. And it adopts double-line splicing process, which is double firm and effectively resists low temperature and gale in winter. Second, the old farmers wish that there are tens of thousands of vents on the cold-proof cloth, which has good air permeability. After the membrane treatment, it can not only have excellent water resistance like a film, but also keep dry at any time under the cold-proof cloth, and the fruit trees are not affected. If it is cold, the fruit will not rot.
