Embodiment Construction
[0034] In order to better understand the present invention, the implementation manner of the present invention will be explained in detail below in conjunction with the accompanying drawings.
[0035] Such as figure 1 As shown, a composite fiber curtain filter spunlaced nonwoven material uses three kinds of fibers, namely copet composite fiber, whitened polyester fiber, and superfine polyester fiber. The three are grasped according to the mass ratio of 1.5:2.5:1 The cotton machine or weighing machine grabs, mixes and loosens through the opening and cleaning equipment, and is transported by the fan to the air pressure cotton box carding machine to form mixed fibers. The mixed fibers are carded into a web by the carding machine, and then undergo spunlace reinforcement, dehydration treatment, and drying It is obtained by machine drying and solidification, calendering, slitting and packaging.
[0036] The specification of the copet composite fiber is fineness 3-5Dtex, length 38-5...
