Embodiment 1

[0030] A non-woven fabric with good air permeability is composed of several layers of fiber webs 8 superimposed.

[0031] A preparation process of a non-woven fabric with good air permeability, which is prepared by a non-woven fabric preparation device with good air permeability, such as Figure 1-6 As shown, the non-woven fabric preparation device with good air permeability includes a base 1 and a top plate 2 . The top plate 2 is placed above the base 1 . A processing assembly 3 is arranged between the base 1 and the top plate 2 . A telescopic rod 4 is connected to the lower surface of the top plate 2 . The machining assembly 3 is provided with two supporting rollers 5 . The supporting roller shaft 5 is sleeved with a rollable processing belt 6 . The telescopic rod 4 is connected with the support roller shaft 5, and the specific steps are as follows:

[0032] 1) Material input: stack the multi-layer fiber webs prepared for non-woven fabrics and input them into the prepar...

Abstract

The invention discloses a non-woven fabric with good air permeability and a preparation process, and aims to provide the non-woven fabric with good air permeability and the preparation process, and the non-woven fabric is good in needling reinforcement and cloth forming effect. The non-woven fabric is formed by superposing multiple layers of fiber webs; a preparation device for the non-woven fabric with good air permeability comprises a base and a top plate; the top plate is arranged above the base; a processing assembly is arranged between the base and the top plate; the lower surface of the top plate is connected with telescopic rods; the processing assembly is provided with two supporting roller shafts; the supporting roller shafts are sleeved with a processing belt capable of rolling; and the telescopic rods are connected with the supporting roller shafts. The invention has the beneficial effects that water discharged from water outlets in the centers of fixed needles can humidify multilayer fibers, so that the fluffy effect of the multilayer fibers is reduced, and the multilayer fibers are easily reinforced to form cloth; movable needles are matched with stop blocks, and the stop blocks can swing through vertical movement of the movable needles, so that water discharge and closing of the water outlets are controlled; the movable needles are connected with springs, so that the puncture effect of the movable needles is stronger, and the reinforcing effect is better; and a heat conducting plate can heat the processed non-woven fabric to obtain the dry non-woven fabric with good air permeability.

Description

technical field [0001] The invention relates to the related technical field of non-woven fabrics, in particular to a non-woven fabric with good air permeability and a preparation process. Background technique [0002] Non-woven fabric is a kind of non-woven fabric. It directly uses polymer slices, short fibers or filaments, etc., firstly restricts the limit through airflow or mechanically, and then strengthens it into a cloth by spunlace or needle punching. When performing acupuncture processing, the multi-layer fiber web has a strong fluffy feeling after stacking, and it cannot obtain a good effect of reinforcing into cloth after acupuncture processing. Contents of the invention [0003] The purpose of the invention is to overcome the disadvantage of poor effect of needle-punched reinforcement into cloth in the prior art, and provide a non-woven fabric with good effect of needle-punched reinforcement into cloth and good air permeability and a preparation process. [0004...
