gsm = grammage / m2
N/5cm = représente la pression en Newton sur 5 cm de
tissu.
MD = sens machine ( c'est à dire Verticale par rapport
au tissu )
CD = sens travers ( Horizontale par rapport au tissu )
SPP = Spunbonded polypropylène ( liage par points )
Un Newton = m x kg x s-_ ( m = mètre ; s = seconde ;
kg = kilogramme ) |

| What use for polypropylen
overalls ? |
These working polypropylen clothes
are light, for short use and therefor cheap.
They remain confortable and ensure a good protection.
Their lifetime varies according to the thickness of the cloth:
A polypropylen layer for a SPP overall and three layers for a SMS overall.
Their delivery is performed to agrobusiness industries, restauration, chimical
industries and in the agricultural field as well.
These clothes are used as well for all cleaning labors, painting, and also in
the medical field. |
