Dear customer Welcome visit our company alibaba web site .below is my company and parts of sms nonwoven machinery introduce .
1. Generality
The design conception of this project is as following:
PP chips ---- Blending and Feeding --- Melting in the Extruder --- Prefiltration
Recycled Materials
Colouful PP Particles -- Spinning -- Cooling with the Side Wind -- Air Dragging
Web forming -- Thermalbonding -- Winding -- Cutting -- End Products
From the figure it can be seen that this PP spunbonding line includes the following parts:'
a. Engineering : Electricity supply and distribution, Airconditioner and Cooling system.
b. Spinning : PP chips feeding, Melt and Extruding, Spinning
c. Web: Web forming , Thermalabonding and Winding
d. Cutting : Semi-manufactured goods, Cutting , Packing
e. Working time is calculated with four groups alternative. It is about 333 days, 8000 hours per year.
2. Production ability, products specification and quality standard
a. Ability : 3000 t/a with the product of 40 g/sq.mtr
b. Products specification : Weight 10-200 g/sq.mtr, width 3.2meters
c. Quality Standard: According to the Chinese standard of PP spunbonding nonwovens.
