Yuav ua li cas los tsim spunbond nonwoven ntaub thiab yaj tshuab nonwoven ntaub

Kev tsim cov PP Spunbond nonwoven npuag:

1. Polymer npaj: Polypropylene (PP) pellets los yog chips yog melted thiab ces extruded los ntawm ib tug spinneret.

2. Spinning: Lub extruded filaments yog ces tshuab los ntawm high-ceev huab cua ntawm ob sab kom haum cov filaments thiab tsim ib tug niaj hnub web.

3. Kev sib khi: Lub vev xaib tau dhau los ntawm lub calender (cov txheej txheem ntawm cov chais) ntawm qhov kub thiab txias kom khi cov filaments ua ke.

4. Kev ua tiav: Cov ntaub yog tam sim no tsim thiab tuaj yeem ua tiav raws li qhov xav tau siv. Qhov no tuaj yeem suav nrog kev kho mob xws li kev tiv thaiv dej los yog dyeing.

Kev tsim cov Meltblown nonwoven npuag:

1. Polymer npaj: Polypropylene (PP) pellets yog yaj thiab ces extruded los ntawm ib tug spinneret.

2. Filament formation: High-velocity air kwj tawg cov extruded filaments rau hauv cov fibers zoo heev.

3. Web tsim: Cov fibers zoo yog random sau mus rau ib txoj siv conveyor los ua ib lub web.

4. Bonding: Lub vev xaib yog tom qab ntawd dhau los ntawm cov rhawv kub uas khi cov fibers ua ke.

5. Kev ua tiav: Cov ntaub yog tsim thiab tuaj yeem ua tiav raws li qhov xav tau siv. Qhov no tuaj yeem suav nrog kev kho mob xws li ua kom tsis muaj menyuam lossis ntxiv cov txheej txheem ua pa.
