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。

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.

根据生产工艺分类,一张思维导图带你简单入门无纺布知识体系:

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:

一张思维导图带你简单入门无纺布

1.水刺无纺布: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.

2.热合无纺布:热粘合无纺布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 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.浆粕气流成网无纺布: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: 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.湿法无纺布: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: 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.纺粘无纺布:纺粘无纺布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。

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.熔喷无纺布:熔喷无纺布的工艺过程:聚合物喂入—熔融挤出—纤维形成—纤维冷却—成网—加固成布。

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

7.针刺无纺布:针刺无纺布是干法无纺布的一种,针刺无纺布是利用刺针的穿刺作用,将蓬松的纤网加固成布。

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.缝编无纺布: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。

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.
