Study on jute/low-melt fiber composite mulching film

The objective of this paper is to provide a biodegradable material in replace of the conventional plastic mulching film to solve the environmental pollution problems.Jute fibers were blended with sheath-core low-melt fibers and were carded into fibre pre-web by using Rando air-laid machine.Then the fiber pre-web was bonded by using the vulcanizing machine in which process the sheath of low-melt fibers was melted and jute fibers of the pre-web were bonded into biodegradable mulching film.The influences of the bonding temperature,time and pressure on the mechanical properties of jute/low-melt fiber composite mulching film were investigated.It is found that the optimal bonding conditios are as follows: the mass ratio of low-melt fiber and jute fiber is 3∶7,pressing temperature is 115 ℃,pressing pressure is 5 MPa,and pressing time is 30 s.
