Kansan Materials Presents Wetlaid Technology


Technology can produce fully dispersible, biodegradable materials for wipes, hygiene, filtration, healthcare and automotive industries

Kansan Materials was established to supply complete wetlaid nonwoven lines and web forming technologies for the manufacturing of fully dispersible, biodegradable and environmentally friendly, sustainable materials for wet wipes, hygiene, filtration, healthcare, automotive, construction and insulation industries to answer the increasing demand for sustainable raw materials. The company is presenting this technology at Techtextil.

Kansan Materials’ wetlaid production line consists of a headbox unit, hydroentanglement unit, a dewatering system, an air-thru dryer and a slitter winder, all developed, designed, engineered and manufactured by Kansan.

A wide range of natural and unnatural fibers can be used in the wetlaid process such as cotton, wool, hemp, jute, coconut, viscose fibers, fibers from PET, PP, aramid, carbon, glass, wood, ceramics and metal. The wetlaid technology allows the use of a combination of various fibers at the same time.

Kansan Materials provides energy-saving high-efficiency systems. The heat recovery system and facility heating are some of the engineering marvels of the Kansan R&D team.

Heat Recovery System: To dry the web in the Air-Thru Dryer, clean air at ambient temperature is heated up to 180°C by burning natural gas. The heated air is then expelled as flue gas at the exhaust after the recirculation in the machine. If the temperature of clean air at the inlet of the machine can be increased then the natural gas energy consumed will decrease.

The flue gas can be mixed with clean air before the inlet at the heat exchanger. The clean air can be heated up to 60-70°C before entering the dryer. This way a significant amount of heat energy is recovered.

Facility Heating: The facility heating and air conditioning work similarly as explained in the heat recovery system. The heated air coming out of the dryer can heat the main water of the facility with the help of a heat exchanger by extending the installation path.

It can also be used to heat the facility environment bypassing certain paths throughout the facility. By heating the mains water, energy saving can be achieved for the hot water to be used in the facility’s toilets and kitchens.
