Kev xaiv ntawm daim ntawv pulp ncaj qha txiav txim siab lub durability ntawmntawv napkins, nrog rau hom fiber ntau, qhov ntev, thiab kev ua cov txheej txheem yog qhov tseem ceeb.
Core Impact Mechanisms
- Fiber hom: Ntoo pulp (softwood/hardwood) yog superior rau non{0}}ntoo pulp (xws li straw, qab zib) nyob rau hauv durability. Softwood pulp muaj cov fibers ntev dua uas tsim muaj zog inter-fiber bonds, hos non-wood fibers luv thiab nkig.
- Fiber ntev: Ntev fibers (xws li, softwood kraft pulp) txhim khu kua muag kuj thiab ntub lub zog. Shorter fibers (xws li, hardwood mechanical pulp) ua rau tsis muaj zog, yooj yim dua -rau- so napkins.
- Kev siv thev naus laus zis: Tshuaj pulping khaws cov fiber ntau zoo dua li cov tshuab pulping, txhim kho durability. Ntxiv cov ntub dej -cov tshuaj muaj zog (piv txwv li, polyamide-epichlorohydrin) thaum lub sijhawm ua haujlwm kuj txhawb dej tsis kam.
Specific Pulp Type Performance
- Softwood chemical pulp: siab tshaj plaws, muaj zog qhuav / ntub dej, haum rau hnyav - cov ntaub so ntswg.
- Hardwood chemical pulp: Lub zog nruab nrab, kev ntxhib los mos zoo dua tab sis qis dua tsim kua muag dua li softwood pulp.
- Mechanical pulp: Tsawg kawg durability, nws yooj yim rau disintegration thaum ntub, siv nyob rau hauv qis -paj ntaub so ntswg.
- Recycled pulp: Durability nyob ntawm qhov chaw; rov ua dua tshiab shortens fibers, txo lub zog piv rau nkauj xwb pulp.
