Lub npe tiag tiag ntawm nonwovens yuav tsum yog nonwovens.
Vim hais tias nws yog ib hom ntaub tsim tsis muaj spinning thiab weaving, nws tsuas yog tsim los ntawm kev taw qhia los yog random kev txhawb nqa ntawm textile luv fibers los yog filaments los ua ib tug fiber web qauv, thiab ces ntxiv dag zog los ntawm mechanical, thermal bonding los yog tshuaj txoj kev.
Nonwovens break through the traditional textile principle, and have the characteristics of short process flow, fast production speed, high output, low cost, wide use and many sources of raw materials. Its main uses can be roughly divided into: (1) medical and health fabrics: surgical clothes, protective clothing, disinfection bags, masks, diapers, women's sanitary napkins, etc; (2) Household decorative cloth: wall cloth, tablecloth, bedspread, bedspread, etc; (3) Cloth for follow-up: lining, adhesive lining, floc, shaped cotton, various synthetic leather soles, etc; (4) Industrial cloth: filter material, insulating material, cement packing bag, geotextile, wrapping cloth, etc; (5) Agricultural cloth: crop protection cloth, seedling raising cloth, irrigation cloth, thermal insulation curtain, etc; (6) Others: Space cotton, heat and sound insulation materials, linoleum, smoke filter, bag bag, tea bag, etc.
Hom tsis yog -woven fabrics
·According to different production processes, non-woven fabrics can be divided into:
1. Spunlaced non- woven npuag: nws txau siab - siab micro dej ntws mus rau hauv ib los yog ntau txheej ntawm fiber ntau mesh, kom cov fibers yog intertwined nrog ib leeg, thiaj li hais tias lub fiber mesh yuav ua tau. txhawb nqa thiab muaj lub zog tshwj xeeb.
2. Thaum tshav kub kub sealing tsis yog- ntaub npuag: nws hais txog kev ntxiv cov fibers lossis hmoov kub- cov ntaub ntawv sib txuas cov khoom siv rau hauv lub vev xaib fiber ntau, thiab tom qab ntawd ntxiv dag zog rau lub vev xaib fiber ntau rau hauv daim ntaub los ntawm cua sov, yaj thiab txias.
3. Pulp airflow net non-woven fabric: nws kuj hu ua hmoov av-dawb ntawv thiab qhuav papermaking tsis yog-woven fabric. Nws siv cov tshuab cua ntws netting kom loosen cov ntoo pulp fiberboard rau hauv ib lub xeev fiber ntau, thiab tom qab ntawd siv cov cua ntws los ua kom cov fibers ntawm cov ntaub thaiv kab hlau rhuav, thiab tom qab ntawd cov fiber ntau mesh tau ntxiv rau hauv daim ntaub.
4. Cov ntaub ntub dej tsis yog- woven npuag: nws yog kom xoob cov ntaub ntawv fiber ntau muab tso rau hauv qhov nruab nrab aqueous rau hauv ib qho fiber ntau, sib xyaw cov khoom siv fiber ntau sib txawv tib lub sijhawm, thiab ua rau cov fiber ntau suspension slurry. Lub suspension slurry yog thauj mus rau lub netting mechanism, thiab fiber yog netted nyob rau hauv lub ntub lub xeev thiab ces ntxiv rau hauv daim ntaub.
5. Spunbonded non-woven npuag: tom qab cov polymer tau raug extruded thiab stretched los ua nruam filaments, cov filaments tau nteg rau hauv ib lub network, thiab cov fiber ntau yog hloov mus rau hauv non-woven npuag los ntawm nws tus kheej. bonding, thermal bonding, chemical bonding lossis mechanical reinforcement.
6. Melt tshuab tsis yog- woven npuag: nws cov txheej txheem thev naus laus zis: kev pub mis polymer - yaj extrusion - fiber ntau tsim - fiber ntau txias - Netting {{6} } reinforcement rau hauv daim ntaub.
7. Koob punched uas tsis yog - woven npuag: nws yog ib hom qhuav tsis yog - woven npuag. Koob xuas nrig ntaus tsis yog- ntaub npuag siv cov nyhuv puncture ntawm rab koob los ntxiv dag zog rau cov ntaub fiber ntau rau hauv daim ntaub.
8. Kev xaws tsis yog- woven npuag: nws yog ib hom qhuav uas tsis yog - woven npuag. Txoj kev xaws yog siv cov warp knitting coil qauv los txhawb lub web fiber ntau, txheej xov paj, tsis yog - cov ntaub ntawv woven (xws li cov ntawv yas, yas nyias hlau ntawv ci, thiab lwm yam) los yog lawv cov kev sib txuas ua ke kom tsis yog {{ 4}}woven npuag.
Cov ntaub uas tsis yog ntaub yog txawv ntawm cov khoom siv niaj hnub. Cov ntaub ntawv zoo sib xws yog woven (knitted los yog woven) los tsim cov ntaub, thaum tsis yog - woven fabrics yog bonded los ntawm sab nraud quab yuam, thiab fibers yog txuas ua ke los tsim fabrics. Nyob rau hauv no txoj kev, lawv muaj peev xwm txawv raws li txoj kev ntawm kev sib raug zoo. Spunlace yog siv lub zog ua kua, thiab acupuncture yog lub zog txhua yam los txuas cov fibers ua ke. Qhov piv txwv ntawm cov duab feem ntau yog cov khaub ncaws woolen (tes xuas tes ua) zoo ib yam li thawj txoj kev knitting, thiab cov nplaum hauv ob sab phlu tsis yog - ntaub npuag.
