Abstract
The utility model discloses a sound cotton is inhaled to two ingredients of special section structure, it is that its cross -section presents the parallel zigzag shaped who arranges by the sheet structure of PP short fiber and the compound menstruation heat bonding formation of PET short fiber, and the PP short fiber is superfine fiber, and the fineness of PET short fiber is 3D. Zigzag shaped's section structure and thinner fibre fineness make inhales the sound cotton and has better fluffy looseness and feel and the better sound ability of inhaling, and the utility model discloses environmental protection, nontoxic, free from extraneous odour, no volatility is gaseous, and is pollution -free, does not contain the carcinogen, does not have similar glass fibre during the operation to the irritability of skin, can carry out cross cutting and die -cut processing, not no powder.
Description
Technical field
The utility model is related to sound-absorbing material technical field, more particularly to a kind of special cross-section structure double-component acoustical cotton.
Background technology
Acoustical cotton has good sound-absorbing, soundproof effect, and it is widely used in building, electrical equipment, vapour as a kind of gasket material
The industries such as car, machinery, but functionally there are many deficiencies in existing acoustical cotton product, for example, traditional double-component acoustical cotton
Cross section structure be usually bias type, and PET material fibre fineness therein is in 6D, due to bias type cross section structure support not
Stabilization and PET fineness are thicker, directly affects the fluffy style and sound absorption qualities of acoustical cotton.It is, thus, sought for one
Plant the acoustical cotton of the dual-use function also while with preferable fluffy degree with excellent sound-absorbing effect.
Utility model content
In order to solve the above problems, it is all to meet that the utility model provides a kind of special cross-section structure double-component acoustical cotton
User's request.
A kind of special cross-section structure double-component acoustical cotton, is formed, its section by short fine being combined of the short fine and PET of PP through heat bonding
In the fold-line-shaped of parallel arranged.
Further, section is in parallel arrangedShape.
Further, PET is short fine in three-dimensional crimp shape, and fibre fineness is 3D.
Further, the short fibres of PP are superfine fibre, and fibre diameter is 1-4 μm.
It is preferably fluffy that the cross section structure of fold-line-shaped of the present utility model and thinner fibre fineness cause that acoustical cotton has
Degree and feel, more preferable sound absorbing power, and the utility model is environmentally friendly, nontoxic, free from extraneous odour, and non-volatility gas is pollution-free, no
Containing carcinogen, the excitant of skin can be die cut and Punching Technology without similar glass during operation, not produced dust.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
In figure, 1, double-component acoustical cotton；2nd, upper pressure roller；3rd, lower compression roller.
Specific embodiment
The utility model is described further below in conjunction with the accompanying drawings.
Double-component acoustical cotton 1 as shown in Figure 1 is short fine short with PET fine compound through heat bonding by blowing and fusing technology by PP
Into the short fine fine swing Formation cross-sections by Shu Wang mechanisms short with PET of PP are in parallel arrangedThe structure type of shape, PP
Short fibre is superfine fibre, and fibre diameter is 1-4 μm, and three-dimensional pore quantity and the face with acoustic contact are increased under equal grammes per square metre
Product, so that the noise of various frequencies is absorbed, with excellent heat-proof quality and sound absorption qualities, protection against the tide, anti-aging, lightweight, PET
Short fine in three-dimensional crimp shape, fibre fineness is less than 6D, and optional 3D, PET are short, and fine three-dimensional crimp structure improves fiber support
Ability, so that the fluffy degree of acoustical cotton is improved, the short fine similarly abilities with excellent absorption of noise of PET of 3D, by fibre
The three-dimensional hole for being formed is tieed up, sound forms backflow in its cavity, effectively realizes the effect of sound insulating and absorbing.
Surface of the present utility model is processed through hot embossing process, while increased the utility model with acoustic contact area
The reflection of sound and the diffusion of sound wave are also reduced, and its internal superfine fibre can effectively cancel out dispersion sound and make it
Reach the volume of minimum.
The utility model in process of production, by regulating and controlling the speed between the upper pressure roller 2 in Shu Wang mechanisms and lower compression roller 3
Official post obtains the upper and lower level of acoustical cotton and produces displacement difference, and then is formedThe cross section structure of type.
The utility model use fibre fineness for the PET of 3D is short fine andThe cross section structure of type causes that acoustical cotton has
There are extraordinary sound-absorbing effect and fluffy style, and any illeffects will not be produced with human body skin directly contact, be a kind of
Nontoxic, tasteless, harmless, free of contamination sound-absorbing material, its deformation resilience rate is high, long service life, imputrescibility, waterproof, protection against the tide,
Permeability is good, anti-aging, wear-resisting, water-fastness, soft, smooth.
The above implementation method only expresses a kind of implementation method of the present utility model, and its description is more specific and detailed
Carefully, but can not therefore and be interpreted as the limitation to the utility model the scope of the claims.It should be pointed out that general for this area
For logical technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these are all
Belong to protection domain of the present utility model.
