近代,在蔬菜生产上出现了一类新的覆盖材料,这就是“无纺布”。它在国外的推广速度很快,对蔬菜生产所起的作用很大,所以,有人把它称之为蔬菜生产上的第二代“白色革命”。无纺布用化学纤维为原料,铺覆成网,采用树脂或热轧粘结而成。纤维的生产通过特定形式的纺丝过程,所以叫非织造布更合适。不过称“无纺布”已成习惯,就不必改称非织造布了。无纺布由于制造工艺比普通纺织布大为简化,成本也大幅度降低,所以在农业生产上才有可能应用。无纺布和塑料
In modern times, a new type of covering material appeared in vegetable production. This is “non-woven fabric.” Its promotion abroad is fast and has a great effect on the production of vegetables. Therefore, some people call it the second generation “white revolution” in vegetable production. Non-woven fabric with chemical fiber as raw material, covered with mesh, using resin or hot-rolled bonding. The production of fibers through a specific form of spinning process, so called non-woven more appropriate. However, “non-woven” has become a habit, you do not have to rename the non-woven fabric. Nonwovens due to the manufacturing process than ordinary textile greatly simplified, the cost is also greatly reduced, so it is possible to apply in agricultural production. Non-woven and plastic
