Ukulawulwa kwekhwalithi kuyadingeka kunoma iyiphi imboni, futhi abakhiqizi abalukiweyo nabo banjalo. Ukuze kuqinisekiswe ikhwalithi yemikhiqizo yabo, abakhiqizi bezikhwama ezilukiwe ze-pp badinga ukukala isisindo nokuqina kwendwangu yabo njalo. Enye yezindlela ezivame ukusetshenziswa ukukala lokhu yaziwa ngokuthi 'i-GSM' (amagremu ngemitha yesikwele).

Imvamisa, sikala ukushuba kweIndwangu yokwelukiwe ye-PPku-GSM. Ngaphezu kwalokho, iphinde ibhekisele ku-"Denier", okubuye kube inkomba yokulinganisa, ngakho-ke sibaguqula kanjani laba ababili?

Okokuqala, ake sibone ukuthi i-GSM ne-Denier zisho ukuthini.

1. Iyini i-GSM yezinto ezilukiwe ze-pp?

Igama elithi GSM limele amagremu ngemitha yesikwele. Kuyiyunithi yokulinganisa esetshenziselwa ukunquma ukujiya .

2. Yini i-Denier?

I-Denier isho amagremu e-fiber nge-9000m ngayinye, iyiyunithi yokulinganisa esetshenziselwa ukunquma ukujiya kwefayibha yemicu ngayinye noma imicu esetshenziswa ekudaleni izindwangu nezindwangu. Izindwangu ezinenani eliphezulu le-denier zivame ukuba ugqinsi, ziqine, futhi ziqine. Izindwangu ezinenani eliphansi le-denier zivame ukuba mhlophe, zithambile, futhi zibe silky.

Khona-ke, ake senze ukubala ecaleni langempela,

Sithatha umqulu wetheyiphu ye-polypropylene (intambo) emgqeni wokukhiqiza ophumayo, ububanzi obuyi-2.54mm, ubude obuyi-100m, nesisindo esingu-8grams.

I-Denier isho amagremu entambo nge-9000m ngayinye,

Ngakho, i-Denier=8/100*9000=720D

Qaphela: - Ububanzi beTape(Intambo) abufakiwe ekubaleni i-Denier. Futhi kusho ukuthi intambo yamagremu ku-9000m ngayinye, noma yikuphi ububanzi bentambo.

Uma weluka le ntambo ibe yindwangu yesikwele engu-1m*1m, ake sibale ukuthi isisindo sizoba sini nge-square meter (gsm).

Indlela 1.

I-GSM=D/9000m*1000mm/2.54mm*2

1.D/9000m=amagremu imitha ubude

2.1000mm/2.54mm=inani lentambo imitha ngayinye (faka i-warp ne-weft bese kuba *2)

3. Intambo ngayinye ukusuka ku-1m*1m ubude bungu-1m, ngakho-ke inombolo yocingo nayo iyingqikithi yobude bentambo.

4. Khona-ke ifomula yenza indwangu yesikwele engu-1m*1m ilingane nentambo ende.

Iza kufomula eyenziwe lula,

I-GSM=DENIER/INYUMBA UBUNZI/4.5

I-DENIER=GSM*UBUNZI BOMZIMBA*4.5

Qaphela: Isebenza kuphelaPP izikhwama ezilukiweyoimboni yokuluka, futhi i-GSM izovela uma ilukwe njengezikhwama zohlobo olulwa nokushelela.

Kunezinzuzo ezimbalwa zokusebenzisa isibali se-GSM:

1. Ungakwazi kalula ukuqhathanisa izinhlobo ezahlukene pp nokwelukiweyo Indwangu

2. Ungaqinisekisa ukuthi indwangu oyisebenzisayo ingeyekhwalithi ephezulu.

3. Ungaqinisekisa ukuthi iphrojekthi yakho yokuphrinta izohamba kahle ngokukhetha indwangu ene-GSM efanelekile yezidingo zakho.
