The invention relates to an automobile roof knitted fabric and a preparation method and application thereof. The automobile roof knitted fabric comprises a PET surface layer, a PU layer and a PET bottom layer which are sequentially arranged in a stacked mode. The stripping force between the PET surface layer and the PU layer is greater than 15 N; and the stripping force between the PU layer and the PET bottom layer is greater than 8 N and less than 10 N. When the knitted fabric is compounded, the stripping force between the fabric layer and a PU upper layer is greater than 15 N, and meanwhile,the stripping force between a PU lower layer and a non-woven fabric is greater than 8 N and less than or equal to 10 N, so that the effects that the cutting is easy to separate, the covered edge is easy to tear, the edge covering precision is improved, and consumables are reduced are achieved.
本发明涉及一种汽车顶蓬针织面料及其制备方法和应用,所述汽车顶蓬针织面料包括依次层叠设置的PET表层、PU层和PET底层;所述PET表层与PU层间的剥离力大于15N;所述PU层与PET底层间的剥离力大于8N且小于10N。本发明在对针织面料进行复合时,使得面料层与PU上层的剥离力大于15N,同时使得PU下层与无纺布之间剥离力大于8N且小于等于10N,实现切割容易脱离,包边容易撕边,提高包边精度,减少耗材。
