Kuwongolera kwaubwino ndikofunikira pamakampani aliwonse, ndipo opanga nsalu nawonso nawonso. Pofuna kuonetsetsa kuti katundu wawo ali wabwino, opanga zikwama za pp amafunika kuyeza kulemera ndi makulidwe a nsalu zawo nthawi zonse. Imodzi mwa njira zodziwika bwino zoyezera izi imadziwika kuti 'GSM' (ma gramu pa sikweya mita).

Nthawi zambiri, timayesa makulidwe aPP nsalu nsalumu GSM. Kuphatikiza apo, imatanthawuzanso "Denier", yomwe ilinso chizindikiro choyezera, ndiye timatembenuza bwanji awiriwa?

Choyamba, tiyeni tiwone zomwe GSM ndi Denier amatanthauza.

1. Kodi GSM ya pp woven material ndi chiyani?

Mawu akuti GSM amaimira magalamu pa lalikulu mita. Ndi muyeso womwe umagwiritsidwa ntchito kudziwa makulidwe .

2. Kodi Denier ndi chiyani?

Denier amatanthauza fiber magalamu pa 9000m, ndi muyeso womwe umagwiritsidwa ntchito kudziwa makulidwe a ulusi kapena ulusi womwe umagwiritsidwa ntchito popanga nsalu ndi nsalu. Nsalu zokhala ndi zokana kwambiri zimakhala zokhuthala, zolimba, komanso zolimba. Nsalu zokhala ndi chiwerengero chochepa chokanira zimakonda kukhala zofewa, zofewa komanso zonyezimira.

Ndiye, tiyeni tiwerenge pazochitika zenizeni,

Timatenga mpukutu wa tepi ya polypropylene (ulusi) kuchokera ku mzere wopangira extruding, m'lifupi 2.54mm, kutalika kwa 100m, ndi kulemera kwa 8grams.

Denier amatanthauza ulusi wa magalamu pa 9000m,

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

Zindikirani: - Kuchuluka kwa tepi (Yarn) sikuphatikizidwa pakuwerengera Denier. Momwemonso zimatanthawuza ulusi wa magalamu pa 9000m, kaya ndi m'lifupi mwa ulusi.

Tikamaluka ulusiwu kukhala 1m*1m sikweya nsalu, tiyeni tiwerengere kulemera kwake komwe kudzakhala pa lalikulu mita (gsm).

Njira 1.

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

1.D/9000m=magilamu pa mita kutalika

2.1000mm/2.54mm=chiwerengero cha ulusi pa mita (kuphatikizapo warp ndi weft ndiye *2)

3. Ulusi uliwonse kuchokera pa 1m*1m ndi utali wa 1m, kotero nambala ya ulusi ndi kutalika kwake konse.

4. Kenako ndondomekoyi imapangitsa kuti nsalu ya 1m * 1m ikhale yofanana ndi ulusi wautali.

Zimabwera ku formula yophweka,

GSM=DENIER/WARN WIDTH/4.5

DENIER=GSM*KUWIRIDWA KWA NYAZI*4.5

Ndemanga: Zimangogwira ntchitoPP matumba olukamafakitale oluka, ndipo GSM idzawuka ngati yolukidwa ngati matumba amtundu wa anti-slip.

Pali maubwino angapo ogwiritsira ntchito chowerengera cha GSM:

1. Mutha kufananiza mosavuta mitundu yosiyanasiyana ya pp nsalu nsalu

2. Mungathe kuonetsetsa kuti nsalu yomwe mukugwiritsa ntchito ndi yapamwamba kwambiri.

3. Mukhoza kuonetsetsa kuti ntchito yanu yosindikiza idzayenda bwino posankha nsalu ndi GSM yoyenera pa zosowa zanu.
