Coating Process

Base cloth orientation     opening    selvage justifying    coating    curing

Flat padding and cooling    winding

2.Brief Introduction

2.1  The principle of the single dot interlining coating device  process is: first the thermosol powder was softened and shaped on the engraved roller, then passing through the surface of the heated fabric, the melted powder transfer to the fabric surface to fulfill the powder dot transfer, finally, the powder fixed to the surface via curing closely.

2.2  During the whole coating device process, the stability of temperature plays an important role, while the variation of speed exerts direct influence on the temperature change, so in the production, it is essential to master the relationship between the speed and the temperature, as well as how to control parameters of the whole machine.

3.structure and features

3.1  Inlet frame and open-width selvage justifying machine

3.2  Powder dot coating device

3.2.1        This section is the core heart of the whole process, preheating roller is used to preheat the coated fabric for water removal and fabric heating, main heating roller is used to fulfill the thermosol powder transfer, engraved roller is used to soften and shape the powder, auxiliary heating roller is used to assist the powder transfer.

3.3 Dryer

3.3.1 The dryer is used to cure the fabric coated with thermosol powder , thus the powder is fixed on the fabric surface closely.

3.4  Flat padding and cooling device

3.4.1        Cooling the manufactured products, parts of them should be processed calendaring finish.

3.5  Winding device

3.5.1        Mechanical friction winding or hydraulic winding is available for product winding.

4        Operation and Adjustment

4.1Raise the temperature for preheating

4.2Frame head coating.

4.3Regulation of temperature and speed during the whole process
