About Nonwoven Fabric

Manufacturing Process

Unitika uses two methods - spunbond method and spunlace (hydroentangling) method - to produce nonwoven fabric.

Spunbond method

Filaments spun by melting resin chips are spread on a net directly from a spinning nozzle and randomly deposited to form a web and then bonded in the form of a sheet through thermal bonding or by other means.

(1) Melt polymer chips (raw material).

↓

(2)Form filaments by spinning the molten polymer and stretching the molten filaments.

↓

(3)Separate and spread fiber bundles of many filaments, and lay down the fibers on a net to form a web.

↓

(4) Bind the fibers in the form of a sheet through thermal bonding and perform embossing.

↓

(5) Perform special in-line processing such as calender processing.

↓

(6) Wind up the sheet.

Spunbond method

Spunlace (hydroentangling) method

Staple fibers such as cotton are formed a drylaid web by carding. High-pressure liquid stream is performed on the drylaid web, a nonwovens fabric is formed by entangling the staple fiber.

(1) Organize fibers by carding.

↓

(2) Form a drylaid web.

↓

(3) Staple fibers are entangled together by high-pressure liquid stream, and form a nonwoven fabric. Also, give patterns using the water pressure.

↓

(4) Perform special in-line processing.

↓

(5) Dry and wind up the sheet.
