Composite spunlace nonwovens with high tear strength, mainly used as base fabric in artificial leather and synthetic leather. Lay a fiber layer on one or both sides of the needle-punched non-woven fabric, especially the spun-bonded needle-punched non-woven fabric, and combine them together by spunlace processing to form a high tear strength, and the cross-section is like natural leather. Shaped composite spunlace nonwovens.
Description
本实用新型涉及一种高撕裂强度的复合水刺非织造布。众所周知，水刺非织造布广泛地用作人造皮革或合成皮革的基布。由于水刺非织造布在加固过程中没有完全的纤维转移，因此其撕裂强度较低，制约了水刺非织造布的应用。为此，人们采用了各种方式来解决这个问题，其中主要的一种方法是在水刺非织造布纤维中加纱线的方法，利用纱线增强非织造布的撕裂强度，效果较好。但存在的不足是，在作为皮革应用时，在切割的横截面中出现纱线的头端，破坏了仿皮的感觉。The utility model relates to a composite spunlace nonwoven fabric with high tear strength. As we all know, spunlace nonwovens are widely used as base fabrics for artificial leather or synthetic leather. Since spunlace nonwovens do not have complete fiber transfer during the reinforcement process, their tear strength is low, which restricts the application of spunlace nonwovens. For this reason, people have adopted various methods to solve this problem, one of the main methods is the method of adding yarn to the fiber of the spunlace nonwoven fabric, and using the yarn to enhance the tear strength of the nonwoven fabric, the effect is better . But the deficiency that exists is, when being applied as leather, the head end of yarn appears in the cross-section of cutting, has destroyed the feeling of imitation leather.
本实用新型的目的是提供一种能够克服上述缺点，具有高撕裂强度的复合水刺非织造布。The purpose of this utility model is to provide a composite spunlace nonwoven fabric with high tear strength that can overcome the above-mentioned shortcomings.
为了实现上述目的，本实用新型的技术方案是：采用在针刺无织造布，特别是长丝的纺粘法针刺无织造布的单面或双面铺一层纤维层，并经水刺加工将它们复合在一起，形成了双层或三层的复合结构。In order to achieve the above object, the technical solution of the present utility model is: use the needle-punched non-woven fabric, especially the spun-bonded needle-punched non-woven fabric of the filament to lay a layer of fiber layer on one side or both sides, and spunlace the non-woven fabric Processing combines them together to form a double- or triple-layer composite structure.
由于采用了撕裂强度高的长丝纺粘法针刺非织造布，使得复合后的水刺无织造布具有较高的撕裂强度；由于这种复合结构仍为水刺无织造布，故使其断面呈天然皮革的随机分布的纤维状，具有较好的仿皮革效果；另外，与单层的水刺非织造布相比，由于本实用新型比前者多一层针刺无织造布，而水刺工序都一样，故可提高生产效率。Due to the use of filament spunbonded needle-punched nonwovens with high tear strength, the composite spunlace nonwovens have higher tear strength; since this composite structure is still spunlace nonwovens, Its cross-section is randomly distributed fibrous shape of natural leather, which has better imitation leather effect; in addition, compared with single-layer spunlace nonwoven fabric, because the utility model has one more layer of needle-punched nonwoven fabric than the former, The spunlace process is the same, so the production efficiency can be improved.
下面结合附图说明本实用新型的两个实施例。Two embodiments of the utility model are described below in conjunction with the accompanying drawings.
图1为本实用新型的二层结构的裁面示意图。Fig. 1 is a cross-sectional schematic diagram of a two-layer structure of the present invention.
图2为本实用新型的三层结构的截面示意图。Fig. 2 is a schematic cross-sectional view of the three-layer structure of the present invention.
在图1中表示了本实用新型二层结构的实施例。在长丝的纺粘法针刺非织布(2)的上面再铺附一层纤维层(1)，然后将这两层结构采用水刺加工方法复合在一起。In Fig. 1, the embodiment of the two-layer structure of the present utility model is shown. A fiber layer (1) is laid on the spun-bonded needle-punched non-woven fabric (2) of filaments, and then the two layers are composited together by a hydroentanglement process.
在图2中表示了本实用新型三层结构的实施例。在长丝的仿粘法针刺非织造布(2)的两面各铺附一层纤维层，再用水刺加工方法将它们复合在一起。An embodiment of the three-layer structure of the present invention is shown in FIG. 2 . A fiber layer is laid on both sides of the imitation bonded needle-punched nonwoven fabric (2) of filaments, and then they are compounded together by a spunlace processing method.
