O mea masani o pepa, ie ma mea e le lalagaina e masani lava o alava cellulose.O le eseesega i le va o oloa e tolu o loʻo taoto i le auala e tuʻufaʻatasia ai alava.

Ie, lea e pipi'i fa'atasi ai alava e tele lava i le lalagaina fa'ainisinia (fa'ata'ita'iga lalaga).

Pepa, o lo'o fa'apipi'i fa'atasi ai alava cellulose e so'o vaivai vaila'au hydrogen.

-I se fa'atusatusaga, o mea e le'i lalagaina e fa'atasi fa'atasi i se tasi pe sili atu fo'i o auala nei:

-Malosi so'o fa'apipi'i vaila'au.Mo se faʻataʻitaʻiga, resin synthetic, latex poʻo solvent.

Fa'alili alava soso'o (feso'ota'i vevela).

- Fa'alavelave fa'ainisinia o filaments.Mo se fa'ata'ita'iga: vili le lane so'oga (fa'aigoa vai), tu'i nila po'o so'ai su'i.

O le ituaiga o oloa e le'i lalagaina ua mae'a e fa'apea:

-ufiufi.Eg mo napekini.

-Geotextiles (geosynthetics).Mo se faʻataʻitaʻiga, ia faʻamalosia le faʻafefe o le eleele poʻo le faʻafefe vai ile inisinia.

-Pepa faufale.Mo se faʻataʻitaʻiga: faʻavaa laupapa taualuga, pepa manava (faʻaaogaina mo puipui fau fale), ufiufi fola.

-Tyvek oloa.Fa'ata'ita'iga, fa'amau fa'a-tisiki, teutusi.

-isi oloa.Mo se faataitaiga: solo susu;solosolo;Ipu laulau;taga lauti;Laei la'ei;Togafitiga fa'afoma'i (fa'ata'ita'iga o ofu tipitipi, matapulepule, pulou, ufiufi seevae, fa'aofuina o manu'a);Filifiliga (ta'avale, mea fa'aoga ea, ma isi);Va'a ma'a;Fa'afolafola kapeta;Su'u suau'u.

E ui lava o ie e le o lalagaina e masani lava ona manatu o ni mea lafoa'i, ae o le mea moni, o se vaega tele o na mea o mea tumau.

E fa'afefea ona fa'aoga mea e le'i lalagaina?

E ese mai i fa'amatalaga faigofie, o nei ie fa'ainisinia e tatala ai foi se lalolagi fou mo ituaiga uma o alamanuia.

O mea e le'i lalagaina e mafai ona avea ma ie fa'aaoga e fa'atapula'a le ola po'o ie umi tele.O ie e le'i lalagaina ei ai ni galuega fa'apitoa, e pei o le fa'afefeteina, fa'afefe vai, maufetuuna'i, fa'agasolo, vaivai, malosi, fa'alumaina o le afi, fa'amama, fa'aalili, fa'amama, fa'ama'i siama ma sterility.O nei uiga e masani ona tuʻufaʻatasia e fatu ai se ie talafeagai mo se galuega faʻapitoa, aʻo ausia se paleni lelei i le va o le ola o oloa ma le tau.E mafai ona latou fa'ata'ita'i i foliga vaaia, fua ma le malosi o ie, ma e mafai ona lapo'a pei o le fa'atumu sili ona mafiafia.

O nisi nei o meatotino e mafai ona maua i le fa'aogaina o mea e le'i lalagaina:

Suavai vai, pa puipui siama, faʻafefeteina, mumu mumu, faʻafefe vai, elasticity, vaivai, faʻalautele malosi ma fufulu.

I aso nei, o loʻo faʻateleina le faʻafouina o mea e le faʻaaogaina ma le faʻateleina o le manaʻoga mo i latou, lea e toetoe lava a maua ai avanoa le faʻatapulaʻaina mo pisinisi eseese, e aofia ai:

Fa'ato'aga, ufiufi, fa'alava lavalava, taualuga o ta'avale, totonu o le ta'avale, kapeta, fa'ainisinia sivili, ie, napekini lafoa'i, teutusi, solo susu a le fale ma le tagata lava ia mo le afifiina o fale, oloa tumama, fa'amaufa'ailoga fa'amama, oloa tamea, mea fa'asoifua maloloina.

Pepa solo e leai se pefu
