PP 紡粘無紡布
無紡布的確切名稱應是非織造布，或叫不織布。因為它是一種不需要紡紗織布而形成的織物，只是將紡織短纖維或者長絲進行定向或隨機撐列，形成纖網結構，然后采用機械、熱粘或化學等方法加 固而成。
PP無紡布高強度、耐高溫性能好（可在150℃環(huán)境中長期使用）、耐老化、抗紫外線、延伸率高、穩(wěn)定性和透氣性好、耐腐蝕、隔音、防蛀、無毒。非織造布突破了傳統(tǒng)的紡織原理，并具有工藝流程短、生產速度快，產量高、成本低、用途廣、原料來源多等特點。
主要特點表現：
- 質輕：聚丙烯原料比重僅0.9，蓬松；性手感好
- 柔軟：成品柔軟度適中，具舒適感；
- 特性：不發(fā)霉，不蛀蟲，堿腐蝕；
- 抗菌：屬化學鈍性物質，能隔離液體內細菌；
- 無毒：燃燒無毒、無異味，不刺激皮膚；
- 環(huán)保：可降解，無味，且無任何遺留物質；
主要用途大致可分為：
PP無紡布是一種有較好透氣性、吸濕性和透光性的新型覆蓋材料，具有御寒保溫、防霜凍、防日光曝曬等作用。且重量輕、耐腐蝕、壽命長（4-5年）。
無紡布根據生產工藝可以分為：
-
水刺無紡布 | Spunlaced nonwoven fabric是將高壓微細水流噴射到一層或多層纖維網上，使纖維相互纏結在一起，從而使纖網得以加固而具備一定強力。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
-
熱合無紡布 | Thermally bonded nonwoven fabric是指在纖網中加入纖維狀或粉狀熱熔粘合加固材料，纖網再經過加熱熔融冷卻加固成布。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
-
紡粘無紡布 | Spunbonded nonwoven fabric是在聚合物已被擠出、拉伸而形成連續(xù)長絲后，長絲鋪設成網，纖網再經過自身粘合、熱粘合、化學粘合或機械加固方法，使纖網變成無紡布。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.
-
熔噴無紡布 | Melt blown nonwoven fabric其工藝過程：聚合物喂入 --- 熔融擠出 --- 纖維形成 --- 纖維冷卻 --- 成網 --- 加固成布。Its technological process: polymer feeding -- melt extrusion -- fiber formation -- fiber cooling -- mesh -- reinforcement into cloth..
-
漿粕氣流成網無紡布 |Pulp air flow into net non-woven fabric又可稱做無塵紙、干法造紙無紡布。它是采用氣流成網技術將木漿纖維板開松成單纖維狀態(tài)，然后用氣流方法使纖維凝集在成網簾上，纖網再加固成布。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..
-
濕法無紡布 | Wet process nonwoven fabric將置于水介質中的纖維原料開松成單纖維，同時使不同纖維原料混合，制成纖維懸浮漿，懸浮漿輸送到成網機構，纖維在濕態(tài)下成網再加固成布。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.
-
縫編無紡布 | Stitch knitted non-woven fabricc干法無紡布的一種，縫編法是利用經編線圈結構對纖網、紗線層、非紡織材料（例如塑料薄片、塑料薄金屬箔等）或它們的組合體進行加固，以制成無紡布。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.
