Uma sikhuluma ngezixubho, wonke umuntu ujwayelene nazo.Njalo ekuseni nakusihlwa, kudingeka sisebenzise isixubho ukuze sihlanze izinyo ngaphambi kokuvuka noma ukulala.Kuyisidingo ekuphileni kwethu kwansuku zonke.
Amasiko amaningi asendulo emhlabeni ayevame ukuxubha nokuxubha amazinyo ngamagatsha noma izingcezu ezincane zokhuni.Enye indlela evamile ukuhlikihla amazinyo nge-baking soda noma ushoki.
Izixubho ezinezinwele ezinsundu zavela eNdiya nase-Afrika cishe ngo-1600 BC.
Ngokusho kwe-American Dental Association, uMbusi uXiaozong waseShayina ngo-1498 naye wayenebhulashi lamazinyo elifushane, eliqinile elenziwe ngomhlwenga wengulube owafakwa esibanjeni sethambo.
Ngo-1938, ikhemikhali ye-DuPont yethula isixubho esine-synthetic fiber esikhundleni samabristle ezilwane.Isixubho sokuqala esinezintambo zenayiloni safika emakethe ngoFebhuwari 24, 1938.
Isixubho esinjalo esibonakala silula, senziwa kanjani, futhi yimuphi umshini ozosetshenziswa?
Imishini yehadiwe okudingeka ilungiselelwe ukukhiqizwa kwesixubho yithuluzi lokugaya isixubho, umshini wokubumba umjovo, umshini womjovo weglue, umshini wokuthungatha, umshini wokusika, umshini wokusika, umshini wokufaka isitembu se-foil oshisayo, umshini wokupakisha neminye imishini.
Okokuqala, ngokombala wesixubho esizokhiqizwa, hlanganisa izinto nezinhlayiya zepulasitiki nombala wezinhlayiyana, ugovuze ngokulinganayo bese ufaka emshinini wokubumba umjovo wokushisa okuphezulu.
Ngemuva kokuphuma kwekhanda lebhulashi, kuyadingeka ukusebenzisa umshini we-tufting.I-bristle ngokuvamile ihlukaniswe yaba izinhlobo ezimbili: inayiloni nama-bristle kasilika acijile.I-degree yayo ethambile futhi eqinile ihlukaniswa ngokujiya, ukuqina kuya kuba nzima.
Sebenzisa umshini wokunquma ngemva kokuqeda ukuhlanganisa.I-bristle ingenziwa ibe yizimo ezihlukahlukene, njengezinwele eziyisicaba, izinwele ze-wavy, njll.
Nakuba isixubho sincane, kodwa inqubo yayo yokukhiqiza iyinkimbinkimbi futhi iyinkimbinkimbi.
