- 使用纤维或切片 Use fibers or chips
- 不同的纤维固结方式 Variety bonding of fibers
无纺布生产用纤维主要是丙纶（PP）、涤纶（PET）。此外，还有锦纶（PA）、粘胶纤维、腈纶、乙纶（HDPE）、氯纶（PVC）。按应用要求，无纺布分为一次性应用型和耐用型两大类。
Nonwoven fabrics are mainly made of polypropylene (PP) and polyester (PET). In addition, there are nylon (PA), viscose fiber, acrylic fiber, polyethylene (HDPE), polyvinyl chloride (PVC). According to the application requirements, non-woven fabrics can be divided into two categories: one-time application type and durable type.无纺布是一种非织造布，它是直接利用高聚物切片、短纤维或长丝将纤维通过气流或机械成网，然后经过水刺，针刺，或热轧加固，最后经过后整理形成的无编织的布料。
Nonwoven fabric is a kind of nonwoven fabric, which is a non woven fabric formed by directly using high polymer chips, short fibers or filaments to form a net of fibers through air flow or mechanical network, and then through water pricking, acupuncture, or hot rolling reinforcement, and finally finishing.
根据生产工艺分为：According to the production process, it can be divided into :
热粘合工艺分为热轧和热风。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。
Thermal bonded process is divided into hot rolling and hot air. It refers to adding fibrous or powdery hot melt bonded reinforcing materials into the web, which is then strengthened by heating, melting and cooling.
热风无纺布，是热风粘合（热轧、热风）无纺布中的一种，热风无纺是在纤维梳理成后，利用烘燥设备上的热风穿透纤网，使之受热而得以粘合生成的无纺布。
Hot air non-woven fabric is one of the hot-air bonded (hot-rolled, hot-air) non-woven fabrics. Hot air non-woven fabric is a kind of non-woven fabric that is formed by carding the fibers and then heating the fibers by using the hot air on the drying equipment to penetrate the fiber web.
针刺工艺是干法无纺布的一种，它利用刺针的穿刺作用，将蓬松的纤网加固成布。
Needle-punched technic is a kind of dry nonwovens. it use the puncture function of needles to reinforce the fluffy fibre web into cloth.水刺工艺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。
Spunlaced non-woven fabrics : Spunlaced process is to spray high-pressure micro-water into one or more layers of fiber mesh, so that the fibers intertwined, so that the fiber mesh can be strengthened and have a certain strength.
浆粕气流成网无纺布，指气流成网无纺布又可称做无尘纸、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。
Pulp air-laid non-woven fabrics，also called dust-free paper, dry paper-making non-woven fabrics. It uses air-flow netting technology to loosen the wood pulp fiberboard into a single fiber state, and then uses air-flow method to agglomerate the fibers on the screen curtain, and then reinforce the fibernet into cloth.
缝编无纺布是干法无纺布的一种，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。
Stitchbond nonwoven fabric is a kind of dry non-woven fabrics. Stitching is to use warp knitting coil structure to reinforce fibre web, yarn layer, non-woven materials (such as plastic sheets, plastic thin metal foil, etc.) or their combination to make non-woven fabrics.
湿法无纺布，是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。
Wet non-woven fabrics it's made by loosening the fibre raw materials placed in water medium into single fibers and mixing different fibre raw materials to make fibre suspension slurry. The suspension slurry is transported to the netting mechanism, and the fibers are netted and consolidated into cloth in the wet state.
纺粘无纺布，是纺熔法工艺的一种。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。
Spunbonded nonwovens， It is a kind of spinning and melting process. Spunbonded nonwovens are continuous filaments formed by extrusion and stretching of polymers. The filaments are laid into nets. The nets are then bonded by self-bonding, thermal bonding , chemical bonding or mechanical reinforcement to make the nets non-woven.
熔喷法属于聚合物挤压法非织造工艺。工艺原理是采用高速热空气对模头喷丝孔挤出的聚合物熔体细流进行牵伸，由此形成超细纤维并凝聚在凝网帘或滚筒上，依靠自身粘合成为非织造布。Melt blowning are polymer extrusion technic. The principle of the process is to use high-speed hot air to draw the polymer melt which is extruded from the spinneret hole of the die head, so as to form the ultra-fine fiber, which is condensed on the screen curtain or roller, and becomes the nonwovens by self bonding.喷丝的原理如下图：The principle of spinneret is as follows:
