纺粘无纺布的主要用途
The main use of spunbonded nonwoven fabrics
纺粘无纺布的主要材料是涤纶和丙纶。
The main materials of spunbonded nonwovens are polyester and polypropylene.
纺粘无纺布的主要产品有丙纶、涤纶（长纤、短纤）无纺布，我们最常见也最常用到的应用就是无纺布袋、无纺布包装等；对于纺粘无纺布的辨认较容易，一般双向牢度好，一般纺粘的无纺布的轧点是菱形的。
The main products of spunbonded non-woven fabric are polypropylene, polyester (long fiber, short fiber) non-woven fabrics. The most common and most commonly used applications are non-woven cloth bags, non-woven fabric packaging, etc.; the identification of spunbonded nonwoven fabrics is easy, general bi-directional fastness is good, and the rolling point of generally spunbonded non-woven fabrics is diamond.
应用的层面还可以做鲜花包装布、箱包布等等，耐磨损、牢固手感好等等的特性，让他成为制作这类产品的最好选择。
The application level can also be made of flowers packing cloth, bags and so on, wear resistance, strong feel good and so on, making him the best choice for making such products.

丙纶：聚合物（ 聚丙烯+回料）——大螺杆高温熔融挤出——过滤器——计量泵（定量输送）——纺丝（纺丝入口上下拉伸抽吸）——冷却——气流牵引——网帘成网——上下压辊（预加固）——轧机热轧（加固）——卷绕——倒布分切——称重包装——成品入库
Polypropylene: polymer (polypropylene + return) - high temperature melt extrusion of large screw - Filter - metering pump (quantitative delivery) - spinning (spinning and drawing) - cooling - Air traction - net curtain - Net - up and down roller (pre reinforcement) - rolling mill (reinforcement) - winding - Reverse cutting - weighing packaging - finished product storage
