1. Keeb Kwm Kev Txhim Kho Luv luv ntawm Kev Lag Luam Cov Ntaub Ntawv huv huv
Cov evolution ntawm cov ntaub so ntswg huv yog ze rau cov khoom siv tshiab thiab kev coj noj coj ua ntawm kev coj khaub ncaws:
Thaum Ntxov 20th Century (Primitive Stage): Ua ntej kev tsim khoom lag luam, cov poj niam siv cov ntaub qhwv rov qab siv tau (linen / paj rwb) lossis cov ntaub ntawv ntuj (moss, quav nyab). Cov kev xaiv no tsis huv, loj heev, thiab tsis muaj dej xau- pov thawj tiv thaiv.
Xyoo 1920 (Industrialization Takeoff): Thawj cov ntaub so ntswg uas siv tau pov tseg (Kotex los ntawm Kimberly-Clark) tau tsim tawm, ua los ntawm cov ntaub ntoo thiab cov ntaub qhwv. Nws tau pib ua lag luam rau cov kws saib xyuas neeg mob thaum Ntiaj Teb Tsov Rog Thoob Ntiaj Teb thib Ib (rau kev kho mob) ua ntej yuav rov ua dua tshiab rau kev coj khaub ncaws. Txawm li cas los xij, nws kim heev thiab tsis siv dav.
Xyoo 1950-1960 (Core Material Breakthrough): Lub invention ntawmSuper absorbent polymer (SAP)nyob rau hauv 1961 revolutionized kev lag luam. Hom zoo li P&G's Always (1983) tau koom ua ke SAP rau hauv cov cores, ua kom muaj peev xwm nqus tau zoo thaum txo cov khoom tuab.
1990s-2000s (Kev nplij siab & Diversification): Ultra-cov qauv tsim nyias, paj rwb txheej txheej, thiab cov segmented cores (kom haum zoo dua) tau dhau los ua qhov tseem ceeb. Cov khoom lag luam hauv cheeb tsam (xws li Tuam Tshoj's Ladycare, Nyiv's Sofy) tau tshwm sim, kho cov khoom lag luam rau cov neeg siv khoom hauv zos (xws li, ntev dua hmo ntuj- siv cov ntaub qhwv rau Asian pw tsaug zog).
2010s-Tam sim no (Sustainability & Intelligence): Cov ntaub ntawv biodegradable ( xyoob fiber ntau, pob kws hmoov txhuv nplej siab SAP) thiab cov ntaub qhwv rov siv tau tau txais kev cuam tshuam ntawm ib puag ncig kev txhawj xeeb. Cov ntaub qhwv ntse (nrog ntws- ntsuas ntsuas) kuj nkag mus rau hauv kev ua lag luam, txuas cov khoom siv rau kev coj khaub ncaws.
2. Cov ntaub ntawv tseem ceeb & lawv cov haujlwm
Cov ntaub so ntswg feem ntau muaj 4 txheej, txhua tus muaj cov yam ntxwv tshwj xeeb:
Daim ntawv saum toj kawg nkaus: Cov txheej hauv kev sib cuag ncaj qha rau ntawm daim tawv nqaij, feem ntau ua los ntawmtsis yog - woven npuag(piv txwv li, paj rwb-zoo li spunlace non-woven) los yogperforated PE zaj duab xis. Qhov tseem ceeb technical indicators:
Porosity: 30-50 microholes / cm² los xyuas kom meej cov kua nkag tau sai (txo cov av noo los ntawm 60% vs. cov ntaub ntawv uas tsis yog perforated).
Softness: Fabric hnyav dua lossis sib npaug li 25g / m² rau daim tawv nqaij - tus phooj ywg kov, tshwj xeeb tshaj yog rau cov pab pawg rhiab heev.
Absorbent Core: Cov txheej txheem ua haujlwm tseem ceeb, feem ntau yog tsim los ntawmntoo pulp fluffthiabSAP (Super Absorbent Polymer):
SAP: Tus ntoo khaub lig- txuas polymer (piv txwv li, sodium polyacrylate) uas tuaj yeem nqus 500-1000x nws qhov hnyav hauv cov kua, xauv cov dej kom tsis txhob rov ua dua. High-zoo SAP muaj lub zog gel Ntau dua los yog sib npaug li 20g / cm² (tiv thaiv gel fragmentation thaum txav).
Composite core (pulp + SAP): Ntsuas qhov nqus nrawm (pulp) thiab lub peev xwm xauv (SAP), txo cov khoom tuab los ntawm 30% piv rau cov ntshiab pulp cores.
Leak-Cov ntaub ntawv pov thawj: Feem ntauPE zaj duab xislos yogwaterproof non{0}} ntaub ntaub, nrog cov dej siab ua haujlwm siab dua lossis sib npaug ntawm 2000Pa kom tiv thaiv sab / rov qab los.
Adhesive Txheej: Kev kho mob-qib kub- nplaum nplaum, ua kom ruaj khov kho yam tsis muaj qhov seem ntawm cov ris tsho hauv qab.
3. Cov Qauv Txheej Txheem rau Cov Ntaub Ntawv huv huv
Txhawm rau kom muaj kev nyab xeeb thiab ua haujlwm tau zoo, kev lag luam thoob ntiaj teb ua raws cov qauv nruj:
Absorption Performance:
Tag nrho lub peev xwm nqus tau: Ntau dua lossis sib npaug ntawm 10x cov khoom hnyav (kuaj raws ISO 9073-11).
Rewetting npaum li cas: Tsawg dua los yog sib npaug rau 2g (tom qab 1-teev siab, kom tsis txhob muaj tawv nqaij tsis xis nyob).
Cov ntsuas kev nyab xeeb:
Cov ntsiab lus formaldehyde: Tsawg dua lossis sib npaug li 30mg / kg (ua raws li Tuam Tshoj tus GB / T 8939-2018 thiab EU's REACH txoj cai).
Microbial txwv: Tsis muaj kev kuaj pom ntawmE. colilos yogStaphylococcus aureus(raws li FDA's 21 CFR 177 tus qauv).
Fluorescent whitening agents: Txwv tsis pub nyob rau hauv feem ntau cheeb tsam (xws li, EU, Nyiv) kom tsis txhob khaus tawv nqaij.
4. Material Trends nyob rau hauv siab -Cov khoom kawg
Nrog cov neeg siv khoom xav tau kev nplij siab thiab kev ruaj ntseg, ob qho kev qhia tau tshwm sim:
Daim tawv nqaij - Cov ntaub ntawv phooj ywg: Organic paj rwb (tso ntawv pov thawj los ntawm GOTS) thiab xyoob fiber ntau sab saum toj nplooj ntawv, uas txo cov kev tsis haum tshuaj los ntawm 40% piv rau cov pa uas tsis yog -woven fabrics.
Eco-Nyob zoo Absorbents: Biodegradable SAP (muab los ntawm pob kws hmoov txhuv nplej siab) thiab pulp los ntawm FSC -tso pov thawj hav zoov, uas decompose 80% nyob rau hauv 180 hnub hauv av (vs . 200+ xyoo rau cov khoom siv tsoos).
