Nchifukwa chiyani nsalu zopanda nsalu zimagawidwa kukhala zofewa komanso zolimba?
Monga nsalu zopanda nsalu, nsalu zopanda nsalu zimapereka zinthu zosiyanasiyana zakuthupi, kuphatikizapo madigiri osiyanasiyana a kufewa ndi kuuma, chifukwa cha kupanga kwawo kwapadera komanso kusankha kwazinthu zopangira. Nkhaniyi ifufuza zifukwa zofewa ndi kuuma kwa nsalu zopanda nsalu ndi zochitika zawo zogwiritsira ntchito.
1. Kusiyana kwa zipangizo za nsalu zopanda nsalu
Zida zazikulu zopangira nsalu zopanda nsalu ndi polypropylene (PP), polyester (PET), viscose fiber, etc. Ulusi wa polypropylene nthawi zambiri umagwiritsidwa ntchito popanga zinthu zolimba zomwe sizinawombedwe chifukwa cha mphamvu zake zambiri komanso kukana kuvala bwino. Ulusi wa poliyesitala nthawi zambiri umagwiritsidwa ntchito popanga zinthu zofewa zosalukidwa chifukwa cha kukhuthala kwake komanso kufewa kwake. Kuphatikizika kosiyanasiyana kwazinthu zopangira ndi ma ratios kudzakhudza mwachindunji kuuma ndi kufewa kwa nsalu zopanda nsalu.
2. Chikoka cha kupanga
Njira zopangira nsalu zosalukidwa zikuphatikiza ndi , kwa spunlace , kukhomerera kwa singano kugudubuza kotentha . Mwachitsanzo, nsalu zopanda nsalu zopangidwa ndi meltblowing nthawi zambiri zimakhala zofewa, pamene kugudubuza kotentha kungapangitse nsalu zosalukidwa kukhala zolimba. Spunlace imagwiritsa ntchito madzi othamanga kwambiri kuti iboole ukonde wa ulusi, kupangitsa kuti ulusiwo ugwirizane, zomwe zimatha kupanga nsalu zopanda nsalu zomwe zimakhala zofewa komanso zolimba.
3. Thupi la ulusi
Maonekedwe a ulusi, monga makulidwe a ulusi (wokanira), mawonekedwe a ulusi wophatikizika, ndi chithandizo chamtundu wa ulusi, zimakhudza kufewa kapena kulimba kwa nsalu zosalukidwa. Ulusi wabwino nthawi zambiri umatha kupanga nsalu zofewa zosalukidwa, pomwe ulusi wokhuthala umatulutsa zida zolimba.
4. Zochitika zogwiritsira ntchito
Kuuma ndi kufewa kwa nsalu zopanda nsalu zimasiyana malinga ndi zosowa za momwe amagwiritsira ntchito:
Makampani azachipatala ndi azaumoyo:
Nsalu zofewa zopanda nsalu: zomwe nthawi zambiri zimagwiritsidwa ntchito popanga mikanjo ya opaleshoni yotaya, masks, mapepala, zovala zachipatala, ndi zina zotero. Zida zimafunika kuti zikhale zofewa komanso zomasuka kuti zichepetse kukangana ndi kupsa mtima kwa khungu lovuta.
Nsalu zolimba zosalukidwa: zitha kugwiritsidwa ntchito popanga ma drapes opangira opaleshoni, zovala zoteteza, ndi zina zotere. Zogulitsazi zimafunikira kuuma kwina kuti zisunge mawonekedwe ndikuletsa kulowa kwamadzi.
Zinthu zapakhomo:
Nsalu zofewa zosalukidwa: zoyenera zogona monga mapepala, mapilo, nsalu zapatebulo, ndi zina zotero, zopatsa kukhudza kofewa komanso kutonthoza.
Nsalu zolimba zosalukidwa: Nsalu zaupholstery zomwe zitha kugwiritsidwa ntchito popanga mipando kapena zotchingira khoma zomwe zimafunikira kuti ziwoneke bwino komanso zowoneka bwino.
Agriculture:
Nsalu zofewa zosalukidwa: Zogwiritsidwa ntchito ngati zotchingira zakukula kwa mbewu m'munda, ziyenera kukhala zofewa kuti zifalikire komanso kuzigwira mosavuta.
Nsalu zolimba zosalukidwa: Zitha kugwiritsidwa ntchito popanga maukonde adzuwa kapena makatani oteteza kutentha, omwe amafunikira kuuma kwina kwake kuti athandizire kapangidwe kake.
Zodzisamalira ndi zaukhondo:
Nsalu zofewa zosalukidwa: zomwe zimagwiritsidwa ntchito muzopukutira zaukhondo, matewera ndi zinthu zina zomwe zimafunikira kufewa kuti zipereke chitonthozo chamunthu.
Nsalu zolimba zosalukidwa: Nthawi zina, monga kulongedza zinthu zopukuta zonyowa, kuuma kwina kungafunike kusunga mawonekedwe a phukusi ndikuthandizira kugwiritsa ntchito.
Mapulogalamu a mafakitale:
Zofewa zopanda nsalu: Pazinthu zosefera, kufewa kungathandize kupereka malo ochulukirapo komanso kusefera bwino.
Zovala zolimba: Pazinthu zoteteza kapena zosavala, kuuma kungapereke mphamvu zamakina komanso kulimba.
Zopakira:
Nsalu zofewa zopanda nsalu: zomwe zimagwiritsidwa ntchito popanga matumba ogula, matumba amphatso, ndi zina zotero, zomwe zimafunika kukhala zofewa komanso zosavuta kuzipinda.
Nsalu zolimba zosalukidwa: Zitha kugwiritsidwa ntchito kupanga mabokosi oyikamo kapena zomangira zomwe zimafunikira kuti zisungidwe bwino komanso kupereka chithandizo china.
Makampani opanga magalimoto:
Ma nonwovens Ofewa: Zida zotchingira mawu zomwe zimagwiritsidwa ntchito mkati mwagalimoto zomwe zimafunika kukhala zofewa kuti zithandizire kukhazikitsa ndikupereka chitonthozo.
Zosaluka zolimba: Pazivundikiro zoteteza kapena zigawo zamagulu ena, kuuma kwina kungafunike kuti chitetezo ndi chithandizo.
5. Mapeto
Kufewa ndi kuuma kwa nsalu zopanda nsalu zimakhudzidwa makamaka ndi mtundu wa zipangizo, njira zopangira, makhalidwe a fiber, zofunikira zogwiritsira ntchito, etc. Opanga adzasintha chiŵerengero cha zinthu zopangira ndi kupanga nsalu zopanda nsalu molingana ndi zochitika zosiyanasiyana zogwiritsira ntchito ndi zofunikira zogwirira ntchito kuti apange zinthu zomwe zimakwaniritsa zosowa zenizeni. Kudzera mwaukadaulo wopitilira muyeso komanso kuwongolera kwazinthu, kuchuluka kwa nsalu zosalukidwa kudzakulitsidwa, kupereka mayankho osiyanasiyana amitundu yonse.
