Spunlace Line Speed and Production Economics
topic
Spunlace line economics are governed by line speed of 100 to 400 metres per minute at fabric widths of 2 to 5 metres, with jet pump energy being the dominant operating cost at 3 to 6 kilowatt hours per kilogram of fabric and water consumption of 50 to 200 litres per kilogram before recycling, with high-pressure pump reliability and jet strip service life being the primary maintenance cost and production efficiency determinants.
Role
Defines the production cost structure of spunlace that must compete with carded bonded and wetlaid nonwovens in the wipes and medical substrate markets, with high-pressure pump energy cost and jet strip replacement frequency being the primary variable cost items requiring systematic management to maintain spunlace competitiveness against alternative nonwoven bonding technologies at equivalent fabric weight and performance specifications.
