What are the aspects of the finishing of nonwovens?
Spunlaced nonwoven principle: The web is conveyed by a conveyor curtain or metal mesh and pre-wetted and pre-sprinkled by a pre-wetting device (roller or curtain) and then into the spunlace area. A number of spunlace device injection of ultra-fine high-pressure water jet, the surface of the fiber due to strong impact and vertical into the network
Common spunlace process: fiber measurement --- open mix --- combing into the network --- the front and back spikes tangent (need strict water treatment) --- drying --- coiling The
First, spunlace non-woven spunlace technology is to spray high-pressure fine water flow to one or more layers of fiber network, so that the fibers tangled together, so that the fiber can be reinforced with a certain strength. Spunlaced non-woven and Other dry nonwovens process similar to the need to go through the preparation of raw materials, open mix, combing into a network (or airlaid or cross-folding network), spunlace reinforcement, finishing, drying, Finished sprinkler inspection and packaging storage. Spunlaced cloth into the network can be dry into a network, it can be wet into the network, or even melt spinning method step by step.
Nonwovens break through the traditional textile principle, and has a short process flow, production speed, high yield, low cost, wide use, raw materials and other characteristics of non - woven fabrics, what types of cloth?
There are many kinds of non-woven fabrics, the exact name of non-woven fabrics should be non-woven, or non-woven, because it is a fabric does not require the formation of woven fabrics, but the textile short fiber or filament Directional or random support, the formation of fiber structure, and then use mechanical, thermal or chemical methods such as reinforcement from.
