Abstract

The invention discloses a method for manufacturing cellucotton felt applied to an automobile hubcap sound insulation cushion. The method comprises the process steps that a, 45 percent to 55 percent of PET short fibers, 30 percent to 45 percent of two-component PET short fibers, 10 percent to 15 percent of PP short fibers, by weight ratio, are placed in a mixer to be stirred; b, an opener carries out opening treatment; c, a carding machine carries out fiber carding treatment; d, a lapping machine carries out lapping treatment; e, a needle machine carries out same-position opposite-puncturing processing. Through the design of the process steps, the cellucotton felt has high strength and the good sound absorption and insulation effect and flame retarding effect, and can be suitable for the automobile hubcap sound insulation cushion well.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for preparing a fiber batt applied to an automobile wheel hub cover sound insulation pad. Background technique [0002] In order to ensure the sound insulation effect of the car, many parts of the car body are equipped with sound insulation structures; among them, the car hub cover sound insulation pad is a sound insulation structure installed in the sheet metal parts on both sides of the rear seat of the car cockpit, and the car hub cover sound insulation pad It can play the role of heat insulation and sound insulation. [0003] For automobile wheel hub cover sound insulation pads, it is generally made of fiber cotton felt; however, due to the defects of the process and materials of the existing automobile hub cover sound insulation pads, the sound insulation effect and flame retardant effect are seriously insufficient, which must be It affects the quality of the car ...
