Nonwoven Fabrics for greenhouses
     Winter greenhouse production of anti-season vegetables, simple use of multi-layer plastic film or the use of increased straw effect is not ideal, in recent years in the use of long fiber non-woven test found in the greenhouse in the small, Cover non-woven insulation, better than the multi-layer film coverage.
First, non-woven insulation effect is good. Using non-woven (specifications 80-100 g / m) + plastic film coverage, generally in the crop growth layer can be maintained at 8 ℃ or more. Specific methods: Qimian with plastic film, ditch covered with straw, and then according to the size of melon, eggplant and other vegetable plants in the greenhouse to take a small shed or in the shed, the first cover a layer of Nonwoven Fabrics, above a layer of film, or First cover the film and then cover the Nonwoven Fabrics. Such as the winter outdoor minimum temperature of 0 ℃ to minus 2 ℃, small, in the shed at least 8 ℃ or more. If you encounter a special cold, you can add a layer of Nonwoven Fabrics and a layer of film, even if the outdoor extreme low temperature down to minus 5 ℃ below the small shed can still be maintained at 5 ℃ or more. In the case of
Second, non-woven moisture absorption strong. The use of Nonwoven Fabricss, shed crops no water droplets, can prevent and reduce leaf disease and rotten fruit. Non-woven day through the sun drying, cloth moisture evaporation at night can absorb the transpiration of leaves out of the water greatly reduce the disease occurred. In the case of
Third, the effort of the province. The use of non-woven film, with an acre of greenhouse, for example, 2 people as long as 10 minutes can be covered or opened, can save labor.
   Nonwoven Fabrics in the construction industry, packaging industry, medical and health industries have a wide range of uses, with the development of non-woven technology, Nonwoven Fabricss are being used in vegetables, flowers and other anti-freeze damage, a plastic film alternative Product.
    1, garden trees transplant and false value. Large trees, small seedlings before planting, the first non-woven shop in the tree pit and then planted, and then covered with nutrient soil, with this method of plantation activities such as high survival rate, and water and fertilizer.
    2, winter greenhouse, open field nursery with (specifications 25! 30 grams / 280 cm) floating cover. Can prevent wind and increase the temperature. Seedbed side of the soil with non-woven compaction, the other side with brick and soil compaction, can also be used bamboo or thick wire made of small shed, the Nonwoven Fabrics covered in the above, surrounded by brick or soil compaction insulation. Covered vegetables, flowers, need more than the sun, so that morning break, evening cover. For floating surface cover, can be increased from the surface of 10 cm temperature of about 2 ゜ C, to improve the ground temperature 1 ~ 2 ゜ C, covered by vegetables can be 5 to 7 days ahead of listing, increase production of about 15%.
    3, for the ceiling with. In the greenhouse, a shed in a Nonwoven Fabrics for the ceiling, ceiling and plastic greenhouse film spacing 15 to 20 cm; the formation of an insulation layer, can improve the shed temperature of 3 ~ 5 ゜ C, opened during the day, closed at night, Must be closed to be effective.
    4, in the small shed outside the cover (specifications 80 to 100 grams, 280 cm), instead of straw curtain insulation, cost savings than the grass curtain 20%, greatly extend the service life; can also be covered in a small shed a layer of non-woven, And then cover the plastic film, can improve the temperature 5 ~ 8 ゜ C.
    5, for sun exposure. With Nonwoven Fabrics directly covered in the seedbed, morning cover, evening expose, can effectively improve Qimiao, whole seedlings. Vegetables, flowers seedlings, in the seedlings, the summer can be directly covered on the seedlings.
    6, in the cold before the advent of vulnerable to the destruction of tea, flowers and other crops, directly covered with non-woven, can effectively reduce the loss of frost damage.
Nonwoven Fabrics in the application of Nonwoven Fabrics has been very popular, such as spunlace medical protective clothing, PP disposable spunbond protective clothing and SMS medical protective clothing. At present, the development of new products in this area includes two aspects: First, the existing materials in the field of clothing applications in the new expansion; Second, the development of new Nonwoven Fabricss.
    In the development of new composite non-woven materials, the United States developed a new type of cotton fiber composite Nonwoven Fabricss, the surface layer of cotton and polypropylene fiber thermal adhesive Nonwoven Fabricss, and spunbond cloth composed of two or three composite materials , Product feel and cotton knitted fabric similar to a good strength and elongation, water absorption and water retention, wicking speed, the advantages of small ball, after finishing, the elongation of 50% when the moment of elastic recovery Rate can reach 83% to 93%, suitable for the production of medical isolation and disposable underwear. In addition, the US military developed a new generation of biochemical protective clothing, make full use of woven, knitted and Nonwoven Fabrics of the advantages of three fabrics, protective clothing outer layer is anti-tear nylon / cotton fiber poplin, after water repellent treatment; Non-woven with activated carbon; the innermost layer for the Tricot warp knitted fabric. Compared with the existing protective clothing, this clothing to the military to provide anti-chemical protection at the same time, but also increase the clothing portability, and reduce costs, can withstand at least 3 times washing.
