热风无纺布：隶属于热风粘合(热轧、热风)无纺布中的一种，热风无纺是在短纤维梳理成后，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: it belongs to one of hot air bonding (hot rolling and hot air) non-woven fabrics. Hot air non-woven is made of short fiber after carding, and it is bonded by hot air through drying equipment and heating.
纺粘无纺布：将聚合物挤出、拉伸，形成连续长丝后，长丝铺设成网，纤网再经过自身粘合、热合、化学粘合或粘合、化学粘合或机械加固方法，使纤网变成无纺布。纺粘无纺布是长纤维但是它的原料是塑料切片。
Spunbonded nonwovens: after extruding and drawing polymer to form continuous filament, the filament is laid into mesh, and then the mesh is transformed into non-woven fabric by self bonding, heat bonding, chemical bonding or adhesion, chemical bonding or mechanical reinforcement. Spunbonded nonwoven fabric is a long fiber, but its raw material is plastic section.
热风无纺布：具有蓬松度高、弹性好、手感柔软、保暖性强、透气透水性好等特点。但其强度较低,易变形。
Hot air non-woven fabric: with high fluffiness, good elasticity, soft feel, strong warmth retention, good permeability and permeable property and so on. But its strength is low and easy to deform.
纺粘无纺布：是不使用纤维，直接从高分子粒子喷丝成网后，经过轧辊加热、加压而成，力学性能优良，抗拉强力、断裂伸长、撕裂强度等指针均优，厚度很薄，但是柔软度、透气性都没有热风无纺布的好。
That is not to use fiber non-woven fabric, net polymer particles directly from the spinneret, passing between the heating and pressing it, excellent mechanical properties, tensile strength, elongation, tear strength and the pointer are excellent, the thickness is very thin, but the softness and breathability are not non-woven good.
所以一般好的纸尿裤的面层都是采用的是热风无纺布的，纺粘无纺布最主要是是使用在医疗卫生的制造，不过也有很多纸尿裤商家为了节省成本会选择采用纺粘无纺布。
So the surface of general good diaper is made of hot air non-woven fabric, spunbonded nonwoven fabric is mainly used in medical and sanitary manufacturing, but there are many diaper businesses in order to save cost, spun bonded nonwovens will be chosen.
