Kwimarike yanamhlanje yabathengi, ukhuseleko lweempahla lubaluleke kakhulu, ngakumbi kwiimveliso ezidibana ngqo nolusu. Iilaphu zihlelwe ngamanqanaba amathathu okhuseleko: Iklasi A, iKlasi B, kunye neKlasi C, nganye ineempawu ezicacileyo kunye nokusetyenziswa okucetyiswayo.
**Amalaphu oKlasi A** amele owona mgangatho uphakamileyo wokhuseleko kwaye alungiselelwe ikakhulu iimveliso zeentsana. Ezi ziquka izinto ezifana namalaphu, impahla yangaphantsi, iibhibhi, iipjama, nezinto zokulala. Iindwangu zeKlasi A kufuneka zihambelane nemimiselo engqongqo, kunye nomxholo we-formaldehyde ongadluli kwi-20 mg / kg. Zikhululekile kwidayi ye-amine enevumba elimnandi kunye nesinyithi esinzima, eqinisekisa ukucaphuka okuncinci kolusu. Ukongeza, la malaphu agcina inqanaba le-pH kufutshane nokungathathi hlangothi kwaye abonise ukukhawuleza kombala ophakamileyo, oko kubenza bakhuseleke kulusu olubuthathaka.
**Amalaphu oKlasi B** alungele ukunxitywa kwabantu abadala yonke imihla, kuquka iihempe, izikipa, iziketi, neebhulukhwe. Ezi zindwangu zinezinga lokhuseleko eliphakathi, kunye nomxholo we-formaldehyde ofakwe kwi-75 mg / kg. Nangona zingenayo i-carcinogens eyaziwayo, i-pH yazo inokuphambuka kancinane ekungathathi hlangothi. Iilaphu zeKlasi B zenzelwe ukuhlangabezana nemigangatho yokhuseleko jikelele, ukubonelela ngokukhawuleza kombala kunye nokuthuthuzela ukusetyenziswa kwansuku zonke.
** I-Class C Fabrics **, ngakolunye uhlangothi, yenzelwe iimveliso ezingaqhagamshelani ngqo nesikhumba, njengeengubo kunye namakhethini. La malaphu anokhuseleko olusezantsi, amanqanaba e-formaldehyde adibana nemigangatho esisiseko. Ngelixa zinokuqulatha izixa ezincinci zeekhemikhali, zihlala ngaphakathi kwemida yokhuseleko. I-pH yamalaphu oKlasi C nawo angaphambuka ekungathathi hlangothi, kodwa akulindelekanga ukuba enze umonakalo omkhulu. Ukukhawuleza kombala kuphakathi, kwaye okunye ukufiphala kunokwenzeka ngokuhamba kwexesha.
Ukuqonda la manqanaba okhuseleko lwamalaphu kubalulekile kubathengi, ngakumbi xa ukhetha iimveliso zeentsana okanye abo banolusu olubuthathaka. Ngokwaziswa, abathengi banokwenza ukhetho olukhuselekileyo olubeka phambili impilo kunye nokuphila kakuhle.
