The utility model discloses a polyester fiber in intermediate level and polypropylene fiber all adhere to except that aldehyde agent layer, enter into this and inhale the sound cotton back when aldehyde substance, the aldehyde molecule carries out the abundant reaction with removing aldehyde agent in the space that polyester fiber and polypropylene fiber constitute, reduces the content of aldehyde substance in the air, and the average effect of eliminating can reach more than 90%.
Description
Technical Field
The utility model relates to a car is with inhaling cotton technical field of sound, in particular to decomposable aldehydes material inhale the sound cotton.
Background
The automobile sound-absorbing cotton material has a wide application range in automobile design and assembly, and has the characteristics of sound absorption, noise reduction, environmental protection and the like. However, most sound-absorbing cotton materials are limited by fiber structures and cost, and the recycled materials or phenolic resins and other binders are adopted to release a lot of aldehydes, which can affect the environment in the vehicle, directly affect the driving comfort of the whole vehicle due to the quality of air in the vehicle, and seriously harm the body and mind of drivers and passengers. Therefore, the problem is mostly relieved by reducing or replacing the use of sound-absorbing cotton materials in the industry, and the sound-absorbing cotton materials capable of purifying the air in the vehicle do not appear at home and abroad.
Therefore, there is a need to provide a new sound-absorbing cotton capable of decomposing aldehydes to solve the above problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a resolvable aldehyde substance inhale sound cotton, have the characteristics that sound absorption effect is good, promote the interior air quality of car.
In order to achieve the above object, the utility model discloses a technical scheme be: the sound-absorbing cotton capable of decomposing aldehyde substances has a three-layer structure and comprises a middle layer and a pair of surface layers thermally attached to two sides of the middle layer, wherein the middle layer is formed by compounding a curled polyester fiber layer with a hollow structure and an isotactic polypropylene fiber layer, aldehyde removing agent layers are attached to the surfaces of the polyester fiber layer and the polypropylene fiber layer, the surface layers are non-woven fabric layers, the thickness of the polyester fiber layer is equal to that of the polypropylene fiber layer, and the thickness of the aldehyde removing agent layers is 1/3 of that of the polyester fiber layer.
Further, the surface of the surface layer is in a mutually vertical and staggered grid shape.
Further, the fineness of the polyester fiber layer is 1-3D, and the fiber length is 38-45 mm.
Further, the fineness of the polypropylene fiber layer is 1-3D, and the fiber length is 38-45 mm.
Further, the gram weight of the non-woven fabric is 45-60g/m2。
Further, the nonwoven fabric is either a spunlace nonwoven fabric or a hot-rolled nonwoven fabric.
Compared with the prior art, the utility model discloses the cotton beneficial effect of inhaling of sound of resolvable aldehyde substance: the polyester fiber and the polypropylene fiber of the middle layer are both attached with aldehyde removing agent layers, and after aldehyde substances enter the sound-absorbing cotton, aldehyde molecules fully react with the aldehyde removing agent in gaps formed by the polyester fiber and the polypropylene fiber, so that the content of the aldehyde substances in the air is reduced, and the average eliminating effect can reach more than 90%.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained without inventive work, wherein:
FIG. 1 is a schematic view of the sound-absorbing cotton of the present invention capable of decomposing aldehydes;
fig. 2 is a schematic view of the surface layer of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Please refer to fig. 1 and fig. 2, the utility model relates to a sound cotton is inhaled to resolvable aldehyde substance, it has three layer construction, laminate in a pair of top layer 2 of 1 both sides in intermediate level including intermediate level 1 and heat, intermediate level 1 is formed for the curling type polyester fiber layer 11 and the isotactic polypropylene fiber layer 12 complex that have hollow structure, polyester fiber layer 11 and polypropylene fiber layer 12 all adhere to except that aldehyde agent layer 13, top layer 2 is the non-woven fabrics layer, polyester fiber layer 11's thickness equals with polypropylene fiber layer 12's thickness, except that aldehyde agent layer 13's thickness is 1/3 of polyester fiber layer 11's thickness, reasonable in design, polyester fiber layer 11 guarantees this and inhales the higher intensity of cotton and better elasticity, polypropylene fiber layer 12 guarantees this and inhales the better gas permeability of cotton of sound. The polyester fiber 11 and the polypropylene fiber 12 of the middle layer 1 are both attached with an aldehyde removing agent layer 13, and after aldehyde substances enter the sound-absorbing cotton, aldehyde molecules fully react with the aldehyde removing agent in a gap formed by the polyester fiber 11 and the polypropylene fiber 12, so that the content of the aldehyde substances in the air is reduced, and the average eliminating effect can reach more than 90%.
