In the water jet impact and rebound flow under the action of the fibers in the fiber web, displacement, interspersed, tangles, hold together, form a plurality of flexible around nodes, so that the fiber net reinforcement. Water jet on Web vertical injection can prevent damage to fiber network structure, and to maximize the use of water jet energy, which helps to improve the performance of spunlaced nonwovens materials. spunlace nonwoven spunlace reinforcement methods are mainly flat screen, rotary drum spunlace reinforcement spunlace reinforcement and drum and flat screen combination of spunlace reinforcement in three forms.
