PP 纺粘无纺布
无纺布的确切名称应是非织造布，或叫不织布。因为它是一种不需要纺纱织布而形成的织物，只是将纺织短纤维或者长丝进行定向或随机撑列，形成纤网结构，然后采用机械、热粘或化学等方法加 固而成。
PP无纺布高强度、耐高温性能好（可在150℃环境中长期使用）、耐老化、抗紫外线、延伸率高、稳定性和透气性好、耐腐蚀、隔音、防蛀、无毒。非织造布突破了传统的纺织原理，并具有工艺流程短、生产速度快，产量高、成本低、用途广、原料来源多等特点。
主要特点表现：
- 质轻：聚丙烯原料比重仅0.9，蓬松；性手感好
- 柔软：成品柔软度适中，具舒适感；
- 特性：不发霉，不蛀虫，碱腐蚀；
- 抗菌：属化学钝性物质，能隔离液体内细菌；
- 无毒：燃烧无毒、无异味，不刺激皮肤；
- 环保：可降解，无味，且无任何遗留物质；
主要用途大致可分为：
PP无纺布是一种有较好透气性、吸湿性和透光性的新型覆盖材料，具有御寒保温、防霜冻、防日光曝晒等作用。且重量轻、耐腐蚀、寿命长（4-5年）。
无纺布根据生产工艺可以分为：
-
水刺无纺布 | Spunlaced nonwoven fabric是将高压微细水流喷射到一层或多层纤维网上，使纤维相互缠结在一起，从而使纤网得以加固而具备一定强力。It is a high pressure micro-water jet to a layer or multilayer fiber network, so that the fiber interentangled together, so that the fiber network can be strengthened and have a certain strength
-
热合无纺布 | Thermally bonded nonwoven fabric是指在纤网中加入纤维状或粉状热熔粘合加固材料，纤网再经过加热熔融冷却加固成布。It refers to the fiber or powdery hot melt bonding reinforcement material is added in the fiber net, the fiber net passes heating melt cooling reinforcement cloth
-
纺粘无纺布 | Spunbonded nonwoven fabric是在聚合物已被挤出、拉伸而形成连续长丝后，长丝铺设成网，纤网再经过自身粘合、热粘合、化学粘合或机械加固方法，使纤网变成无纺布。Is in the polymer has been extruded, stretch and form a continuous filament, filament laid into a net, the net through its own bonding, thermal bonding, chemical bonding or mechanical reinforcement method, so that the net into non-woven fabric.
-
熔喷无纺布 | Melt blown nonwoven fabric其工艺过程：聚合物喂入 --- 熔融挤出 --- 纤维形成 --- 纤维冷却 --- 成网 --- 加固成布。Its technological process: polymer feeding -- melt extrusion -- fiber formation -- fiber cooling -- mesh -- reinforcement into cloth..
-
浆粕气流成网无纺布 |Pulp air flow into net non-woven fabric又可称做无尘纸、干法造纸无纺布。它是采用气流成网技术将木浆纤维板开松成单纤维状态，然后用气流方法使纤维凝集在成网帘上，纤网再加固成布。Also known as dust-free paper, dry paper non-woven fabric.It is to use airflow into the net technology will wood pulp fiberboard open loose into single fiber state, make fiber agglutinate with airflow method next on into the net curtain, fiber net reinforces into cloth again..
-
湿法无纺布 | Wet process nonwoven fabric将置于水介质中的纤维原料开松成单纤维，同时使不同纤维原料混合，制成纤维悬浮浆，悬浮浆输送到成网机构，纤维在湿态下成网再加固成布。The fiber raw materials placed in the water medium are opened and loosened into single fiber, and different fiber raw materials are mixed to make fiber suspension slurry, which is transported to the net forming mechanism, and the fiber is netted and then strengthened into cloth under wet state.
-
缝编无纺布 | Stitch knitted non-woven fabricc干法无纺布的一种，缝编法是利用经编线圈结构对纤网、纱线层、非纺织材料（例如塑料薄片、塑料薄金属箔等）或它们的组合体进行加固，以制成无纺布。A kind of dry non-woven fabric, the stitching method is to use the warp knitting coil structure of the fiber net, yarn layer, non-textile materials (such as plastic sheet, plastic thin metal foil, etc.) or their combination for reinforcement, in order to make non-woven fabric.
