Embodiment 1
[0028] A non-woven fabric preparation process based on hot needle puncture, comprising the following steps:
[0029] S1 (stacking step), the first fabric layer, the second fabric layer and the third fabric layer are stacked together in sequence, the first fabric layer and the third fabric layer are respectively located on both sides of the second fabric layer, and the first fabric layer and the third fabric layer are respectively located on both sides of the second fabric layer. The first fabric layer and the third fabric layer can be integrated with each other;
[0030] S2 (puncturing step), heating the sharp needle so that the temperature of the sharp needle is higher than the melting temperature of the first fabric layer and the second fabric layer, and passing the sharp needle through the first fabric layer, the second fabric layer and the third fabric layer in turn Then pull out.
[0031] For the above process, please refer to the appendix figure 1 , with figure 1 The ...
Embodiment 2
[0036] S1 (stacking step), the first fabric layer, the second fabric layer and the third fabric layer are stacked together in sequence, the first fabric layer and the third fabric layer are respectively located on both sides of the second fabric layer, and the first fabric layer and the third fabric layer are respectively located on both sides of the second fabric layer. The first fabric layer and the third fabric layer can be integrated with each other;
[0037] S2 (puncturing step), heating the sharp needle so that the temperature of the sharp needle is higher than the melting temperature of the first fabric layer and the second fabric layer, and passing the sharp needle through the first fabric layer, the second fabric layer and the third fabric layer in turn Then pull out.
[0038] In this embodiment, the second fabric layer may be wood pulp fiber or paper.
[0039] In this embodiment, the materials of the first fabric layer and the second fabric layer may be the same or ...
Embodiment 3
[0044] A sharp needle, the sharp needle is in the shape of a cone, a groove is arranged on the sharp needle, and the notch of the groove faces the wide-diameter end of the sharp needle.

Abstract
The application discloses a non-woven fabric preparation process based on hot needle puncture, including the following steps: S1 laminating step, sequentially stacking the first fabric layer, the second fabric layer and the third fabric layer together, the first fabric layer The third fabric layer and the third fabric layer are respectively located on both sides of the second fabric layer, and the first fabric layer and the third fabric layer can be fused with each other; S2 piercing step, heating the sharp needle, so that the temperature of the sharp needle is higher than that of the first fabric layer and the second fabric layer For the melting temperature of the second fabric layer, pull out the pointed needle through the first fabric layer, the second fabric layer and the third fabric layer in turn. The invention has the following beneficial effects: the bonding strength between the interlayer fabrics is high, and the energy consumption in the whole process is low.
Description
technical field [0001] The invention relates to the field of fabric preparation, in particular to a non-woven fabric preparation process based on hot needle puncture. Background technique [0002] Patent CN110524984A provides a preparation method of a three-layer non-woven fabric, but the preparation method of this three-layer non-woven fabric is fixed together by the method of spunlace, but the method adopted has the following defects: that is, the strength after fixing Not enough, it still needs to be dried when used, so the energy consumption of the whole preparation process is relatively high. SUMMARY OF THE INVENTION [0003] In view of the above problems, the present invention proposes a non-woven fabric preparation process based on hot needle puncture. [0004] The technical scheme adopted by the present invention is as follows: [0005] A non-woven fabric preparation process based on hot needle puncture, comprising the following steps: [0006] S1 (stacking step...
