無紡布的分類

無紡布的分類

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。

Non-woven 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.

根據生產工藝分類，一張思維導圖帶你簡單入門無紡布知識體系：

According to the production process, According to the production process classification, a mind map gives you a simple introduction to the knowledge system of non-woven fabrics：

1．水刺無紡布：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.

2．熱合無紡布：熱粘合無紡布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 non-woven fabric: Thermal bonded non-woven fabric refers to adding fibrous or powdery hot-melt bonded reinforcing materials into the web, which is then strengthened by heating, melting and cooling.

3．漿粕氣流成網無紡布：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: air-laid non-woven fabrics can also be 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.

4．濕法無紡布：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: Wet non-woven fabrics are 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.

5．紡粘無紡布：紡粘無紡布是在聚合物已被擠出、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: 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.

6．熔噴無紡布：熔噴無紡布的工藝過程：聚合物喂入---熔融擠出---纖維形成---纖維冷卻---成網---加固成布。

Melt-blown nonwovens: Melt-blown nonwovens process: polymer feeding - - melt extrusion - - fiber formation - - fiber cooling - - Netting - - reinforced fabric.

7．針刺無紡布：針刺無紡布是干法無紡布的一種，針刺無紡布是利用刺針的穿刺作用，將蓬松的纖網加固成布。

Needle-punched nonwovens: Needle-punched nonwovens are a kind of dry nonwovens. Needle-punched nonwovens use the puncture function of needles to reinforce the fluffy fibre web into cloth.

8．縫編無紡布：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。

Sewing non-woven fabrics: Sewing non-woven fabrics is a kind of dry non-woven fabrics. Sewing 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.
