- 使用纖維或切片 Use fibers or chips
- 不同的纖維固結方式 Variety bonding of fibers
無紡布生產用纖維主要是丙綸（PP）、滌綸（PET）。此外，還有錦綸（PA）、粘膠纖維、腈綸、乙綸（HDPE）、氯綸（PVC）。按應用要求，無紡布分為一次性應用型和耐用型兩大類。
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.無紡布是一種非織造布，它是直接利用高聚物切片、短纖維或長絲將纖維通過氣流或機械成網，然后經過水刺，針刺，或熱軋加固，最后經過后整理形成的無編織的布料。
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.
根據生產工藝分為：According to the production process, it can be divided into :
熱粘合工藝分為熱軋和熱風。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。
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.
熱風無紡布，是熱風粘合（熱軋、熱風）無紡布中的一種，熱風無紡是在纖維梳理成后，利用烘燥設備上的熱風穿透纖網，使之受熱而得以粘合生成的無紡布。
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.
針刺工藝是干法無紡布的一種，它利用刺針的穿刺作用，將蓬松的纖網加固成布。
Needle-punched technic is a kind of dry nonwovens. it use the puncture function of needles to reinforce the fluffy fibre web into cloth.水刺工藝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。
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.
漿粕氣流成網無紡布，指氣流成網無紡布又可稱做無塵紙、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，然后用氣流方法使纖維凝集在成網簾上，纖網再加固成布。
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.
縫編無紡布是干法無紡布的一種，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。
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.
濕法無紡布，是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，纖維在濕態下成網再加固成布。
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.
紡粘無紡布，是紡熔法工藝的一種。在聚合物已被擠出、拉伸而形成連續長絲后，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。
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.
熔噴法屬于聚合物擠壓法非織造工藝。工藝原理是采用高速熱空氣對模頭噴絲孔擠出的聚合物熔體細流進行牽伸，由此形成超細纖維并凝聚在凝網簾或滾筒上，依靠自身粘合成為非織造布。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.噴絲的原理如下圖：The principle of spinneret is as follows:
