First, impregnation bonding method
Impregnation is the earliest and most widely used method in chemical bonding. It is also called full impregnation or saturated impregnation and is developed from the traditional saturated dyeing process.
Basic process flow:
The web is fed with a binder impregnated bath and after immersion, the excess binder is removed by a pair of rollers or a liquid suction device, and the web is cured by the drying device to become a non-woven material.
According to the liquid and liquid suction methods can be divided into pad type, liquid suction type and liquid suction - liquid combined type, according to the form of net curtain can be divided into single net curtain and double net curtain form.
Features: Hard feel, suitable for interlining.
(b) Single net curtain impregnation (effectively reduce the net curtain loss)
Circular roller roller roller dipping machine
Rotary drum vacuum suction machine
It is an ideal method for producing a thin-bonded nonwoven fabric. The product is suitable for use as an interlining and disposable sanitary material.
(C) Double-network transfer impregnation
The web moves horizontally and clamps up and down, so it is not easily deformed and is suitable for processing wide webs.
