Problems solved by technology

However, the sound insulation cotton produced by this method is easy to emit peculiar smell under high temperature and long-term baking. For example, when the vehicle is parked in the open air in summer, the temperature inside the car can reach 70 or 80 degrees. Cotton emits peculiar smell and affects the ride experience of passengers

Embodiment 1

[0025] Embodiment 1, a kind of processing method of deodorizing sound insulation cotton:

[0026] In step a, manually select the leftovers purchased from the garment factory, pick out the mixed cotton, silk and other fabrics, and collect the remaining chemical fiber fabrics together.

[0027] Step b, soak the picked out chemical fiber cloth in the mixed solution of desizing enzyme and penetrating agent according to the bath ratio of 1:10, the concentration of desizing enzyme is 3g / L, and the concentration of penetrating agent is 5g / L. The temperature of the solution is kept at 50-60° C., soaked and boiled for 20 minutes to desizing.

[0028] In step c, pass the soaked cloth through clean water, rinse it, and then dry it.

[0029] In step d, put the dried cloth into the deodorant solution with a concentration of 5g / L according to the bath ratio of 1:10, and then soak and boil to remove the odor. The soaking temperature is 50-60° C., and the soaking time is 20 minutes.

Abstract

The invention discloses a processing method of odor-removing sound-insulation cotton. The processing method of the odor-removing sound-insulation cotton comprises the steps of selecting, desizing, rinsing and airing, deodorizing, drying, crushing, sizing and the like. The sound-insulation cotton treated by the method has the advantages that the odor diffused by the sound-insulation cotton at a high-temperature state can be reduced relatively well and the odor grade of the sound-insulation cotton is improved.

Description

technical field [0001] The invention relates to a sound insulation device, in particular to a method for processing deodorized sound insulation cotton. Background technique [0002] Sound insulation cotton is the main noise reduction component in the car. The sound insulation cotton is distributed throughout the car to isolate and absorb noise to reduce the noise intensity in the car, especially the engine compartment. In order to control the cost, the existing ordinary cars generally use recycled materials for their own use as the main raw material of the sound insulation cotton. The scraps cut by the garment factory are used to crush them, beat them into flocculation, and then hot press them into a whole piece of sound insulation cotton. However, the sound insulation cotton produced by this method is easy to emit peculiar smell under high temperature and long-term baking. For example, when the vehicle is parked in the open air in summer, the temperature inside the car can ...
