What is the process of non-woven needle punching machine?

The non-woven needle punching machine uses the needle punching method to produce non-woven fabrics through a mechanical action, that is, the needle punching action of the needle punching machine, which reinforces the fluffy fiber web and obtains strong strength.

What is the reason for the uneven thickness of the needle punched non-woven fabric during the production process of the non-woven needle punching machine?

What is the difference between needle punched nonwovens and stitch bonded nonwovens?

What is the reason for the uneven thickness of the needle punched non-woven fabric during the production process of the non-woven needle punching machine?

First of all, it is necessary to confirm which link in the production process of the non-woven needle punching machine is caused by the difference in thickness!

1. Whether the cotton web output by the carding machine is uniform and whether there is thick cotton. If so, check whether the carding gap is loose, and then check whether the feeding part of the carding machine has beating or intermittent cotton jam or there are neps entering the carding machine, then you need to continue to look for the reason in the direction of the feeding box.

2. Whether the speed of the trolley of the screen laminating machine is stable and whether the speed compensation is well adjusted.

3. Whether the needles of the non-woven needle punching machine are worn uniformly, whether there are new and old needles on the same needle punching machine that have not been properly adjusted, one plate is a new needle and the other plate is an old needle and is placed on the line of the machine.

4. Is the ironing machine adjusted?

What is the process of non-woven needle punching machine?

The main drive of the non-woven needle punching machine drives the needle beam, the needle plate and the needle to reciprocate up and down together through the crank-link mechanism. The fluffy web is fed into the needling zone under the grip of the feed curtain. When the needle plate moves downward, the felting needle penetrates the fiber web, and the fiber web is close to the supporting web plate. When the needle plate moves upward, the friction between the fiber web and the felting needle makes the fiber web and the felting needle move upward together, and the fiber web is close to the stripping plate. The feeding and output speeds are matched, which can be intermittently stepped or continuously moved. After the web passes through the needling area, it has a certain strength, density and thickness before being sent to the main needling.

What is the difference between needle punched nonwovens and stitch bonded nonwovens?

The needle punched non-woven fabric produced by the non-woven needle punching machine uses the puncturing action of the needle to reinforce the fluffy fiber web into cloth.

Stitch-bonded non-woven fabrics use warp-knitted loop structures to reinforce webs, yarn layers, non-woven materials, or their combinations to make non-woven fabrics.
