Embodiment Construction
[0019] A production process of spunlace composite high-performance polyphenylene sulfide fiber filter material, which uses polyphenylene sulfide fiber and glass fiber base cloth as raw materials, and the raw materials are inspected--weighing and feeding--feeding into the long curtain-- Cotton blending-fine opening, layering is carded separately by the first carding machine and the second carding machine, and then laid on the cross-lapper respectively, then unwinding-lamination-prewetting, and spunlace by multi-pass spunlace machine - Dehydration, drying - coiling.
[0020] This process links the equipment involved in the production process--carding machine, cross-lapper and final product weight detection to form a comprehensive automatic control closed-loop system. Feedback to the computer, the computer controls to change the process parameters of the lapper and carding machine, automatically compensates and adjusts the uniformity of the fiber web, so as to ensure the uniformi...
