Kuwongolera kwapadera ndikofunikira pa malonda aliwonse, ndipo opanga asodzi alibe tanthauzo. Pofuna kuonetsetsa kuti zinthu zawo, opanga ma pp opangidwa ndi masamba amafunika kuyeza kulemera ndi makulidwe a nsalu yawo pafupipafupi. Njira imodzi yofala kwambiri yomwe imagwiritsidwa ntchito poyesa izi imadziwika kuti 'GSM' (magalamu pa mita imodzi).

Nthawi zambiri, timayeza makulidwe aNsalu yokazingaku GSM. Kuphatikiza apo, kumatanthauzanso "otsutsa", omwe alinso chizindikiro chokwanira, ndiye kuti timatembenukira bwanji awiriwa?

Choyamba, tiwone zomwe GSM ndi wotsutsa amatanthauza.

1. Kodi GSM ya PP yanji?

Mawu akuti GSM amaimira magalamu pamtambo. Ndi gawo la muyeso lomwe limagwiritsidwa ntchito kudziwa makulidwe.

2. Kodi amatsutsa chiyani?

Denier amatanthauza fiber prems pa 9000m, ndi gawo la muyeso womwe umagwiritsidwa ntchito kudziwa kukula kwa ulusi kapena mafilimu omwe amagwiritsidwa ntchito popanga mapangidwe ndi nsalu. Zovala zokhala ndi cholembera chachikulu chimakhala chovuta, cholimba, komanso cholimba. Zovala zokhala ndi cholembera chotsika chimakhala chipolopolo, zofewa, ndi silika.

Kenako, tiyeni tiwerengere pa mlandu weniweni,

Timatenga tepi ya polypropyylene tepi (ulusi) kuchokera pamzere wopangidwa, wamfupi 2.54mm, kutalika kwa 100m, ndi 8grams.

Otsutsa amantha grams pa 9000m,

Chifukwa chake, Denier = 8/100 * 9000 = 720d

Chidziwitso: - tepi (yarn) m'lifupi siliphatikizidwa mu kuwerengera kuwerengera. Zithunzi zikutanthauza kuti yarn magalamu pa 9000m, chilichonse chomwe chili m'lifupi mwake larn.

Mukamatayiratu zaarn mu 1M * nsalu imodzi 1M * tiyeni tiwerenge zomwe zakhala zolemera zomwe zingakhalepo pamtanda (GSM).

Njira 1.

Gsm = d / 9000m * 1000mm / 2.54mm * 2

1.d / 9000m = magalamu pa mita kutalika

2.1000mm / 2.54mm = Chiwerengero cha ulusi pa mita (monganso ntchentche ndi weft ndiye * 2)

3. Ulusi uliwonse kuchokera ku 1m * 1m ndi nthawi yayitali, kotero kuchuluka kwa ulusi kuli kutalika kwathunthu kwa ulusi.

4. Kenako fomulayo imapanga 1m * 1m lalikulu nsalu yofanana ngati yarn yayitali.

Zimabwera njira yosavuta,

GSM = Denier / Yarn Whighthmeth / 4.5

Denier = GSM * Yarn Walifupi * 4.5

Ndemanga: zimangogwiraMatumba a PPKupanga mafakitale, ndipo GSM idzadzuka ngati ikuyenda ngati matumba amtundu wa mbewa.

Pali maubwino angapo ogwiritsa ntchito calcutor:

1. Mutha kuyerekezera mitundu yosiyanasiyana ya nsalu yokazinga

2. Mutha kuwonetsetsa kuti nsalu yomwe mukugwiritsa ntchito ndi yapamwamba kwambiri.

3. Mutha kuwonetsetsa kuti pulojekiti yanu yosindikiza iyake posankha nsalu yokhala ndi GSM yoyenera pazosowa zanu.
