Method for adding a softening and /or debonding agent to a hydroentangled nonwoven material

摘要

Method of adding a softening and/or debonding agent to a fiber web of a hydroentangled nonwoven material comprising cellulose pulp fibers. The softening and/or debonding agent is added in an inline manufacturing process of the hydroentangled nonwoven material, subsequent to the hydroentanglement of the nonwoven material. The softening and/or debonding agent is added by means of a size press or a foulard comprising a soaking step to soak the hydroentangled nonwoven material with the added softening and/or debonding agent, and a pressing step, which causes the added softening and/or debonding agent to penetrate and impregnate the hydroentangled nonwoven material.
