Hydroentanglement (original) (raw)

Property Value
dbo:abstract Spunlace je způsob výroby plošných textilií vzájemným spletením vláken s pomocí vodních paprsků. Spunlace se označuje také jako hydraulické prošívání nebo hydraulické splétání. Technologie spunlace byla vyvinuta v 60. letech 20. století u firmy DuPont, k praktickému použití došlo asi o dvacet let později v USA, Japonsku a v západní Evropě. (cs) Hydroentanglement is a bonding process for wet or dry fibrous webs made by either carding, or wet-laying, the resulting bonded fabric being a nonwoven. It uses fine, high pressure jets of water which penetrate the web, hit the conveyor belt (or "wire" as in papermaking conveyor) and bounce back causing the fibres to entangle. Hydroentanglement is sometimes known as spunlacing, this term arising because the early nonwovens were entangled on conveyors with a patterned weave which gave the nonwovens a lacy appearance. It can also be regarded as a two-dimensional equivalent of spinning fibres into yarns prior to weaving. The water pressure has a direct bearing on the gsm, and strength of the web, and very high pressures not only entangle but can also split fibres into micro- and nano-fibres which give the resulting hydroentangled nonwoven a leatherlike or even silky texture. This type of nonwoven can be as strong and tough as woven fabrics made from the same fibres. (en)
