Description
Technical field
The present invention relates to as supporting the space network used, be specifically related to a kind of there is noise reduction and elastomeric property
Space network.
Background technology
Space network belongs to the products formed of elastic construction, and using thermoplastic elastomer is that strip fibre made by raw material
Dimension, ribbon fibre is curled into space multistory network structure again, and material can re-work recovery and use, and comprises a large amount of sky in structure
Gap, has the most ventilative and lightweight performance, uses as supporting pad and may replace traditional thermoset polyurethane foamed cotton, no
Only can reduce environmental pressure, more give the more preferable comfortableness of product.But when described space network, when compression reaction
Can produce certain noise, these noises are due to the sound occurred when strip crimped fibre rubs, and use as cushion pad
Time, people can be allowed to feel ear-piercing unhappy, when being especially applicable to bedding. a little sound is all likely to result in sleep discomfort, exploitation
There is the space network of the elastomeric property of noise reduction, become aobvious reusing especially in actual applications.
When space network uses the softest elastomer as material, and the sound of network structure compression is the least, but
Using too soft elastomer is material, then this space network supporting force is not enough, sleeps sense discomfort and Long-Time Service is prone to collapse
Fall into, reduce Acceptable life.
When space network uses hollow ribbon fibre structure to replace special solid structure, can promote solid netted
Structure supporting force, but because being the structure of hollow, line footpath is relatively thick again, when compression, is more easy to send bigger noise.
When space network fiber abutment is the most, the sound of network structure compression is the least, but abutment is more
Many expression product densities are the highest, uncontrollable required indentation force deflection.
Summary of the invention
The technical problem to be solved provides a kind of for above-mentioned prior art and has noise reduction, elastomeric property
Space network, improves and supports buckling durability, resilience and the adaptive of product and sound-deadening properties, make this space network
Also have the comfortableness of noise reduction as padded coaming concurrently except having longer service life when using.
The present invention solves the technical scheme that the problems referred to above are used: a kind of have noise reduction, elastomeric property solid netted
Structure, is made up of thermoplastic elastomer, and this space network density is 20～100kg/m3, by two kinds of different kenel fibers
Making, two kinds of different kenel fibers are respectively
(1) doughnut: line footpath, between 0.3～2mm, accounts for the 40～95% of all silk hole count point rates；
(2) solid special fiber, line footpath, between 0.05～0.6 mm, accounts for all silk hole count point rates 5～60%.
Further, thermoplastic elastomer can be ethylene octane copolymer, thermoplastic polyurethane class elastomer, heat
Plasticity polyester elastomer or the polyamide-based elastomer of thermoplasticity.
Preferably, the thickness of described space network is 15～200mm, and material hardness is between 80～98A.
Above-mentioned dimorphism state fiber space network manufacture method is, on extruder, by the heat after measuring pump measures
Plasticity elastomer is depressed in spinning plate, and spinning plate has the silk hole of two kinds of different kenels, can spray doughnut after spinneret,
Line footpath, between 0.3～2mm, accounts for the 40～95% of all silk holes point rate, and solid special line, line footpath between 0.05～0.6mm,
Account for all silk hole count point rates 5～60%.
It is an advantage of the current invention that: doughnut plays the effect improving supporting force, makes product have elastomeric property, it is ensured that
The prolongation in product service life, accounts for the 40～95% of all silk holes point rate, and weight fraction is 70～99.5%.Described solid special
Fiber, owing to line footpath is relatively thin, accounts for the 5～60% of all silk hole count point rates, and weight fraction is 0.5～30%, and its quantity number is to whole
Volume density impact is little.But the addition of solid special fiber, improves when minimal effect space network density
Space network fiber abutment, it is sound-deadening properties that this structure has preferably compression, also improves durability of product, additionally can also
Arrangement regulation and control by solid special fiber increase the sense of touch of space network.
Space network in the present invention uses doughnut and the staggered combination of solid special fiber, and its doughnut rises
To the effect of raising supporting force, as reinforcing bar, play buckling durability and the supportive improving space network, and solid
Heterotypic fibre part, improves space network fiber abutment, makes this structure have preferably compression sound-deadening properties, also increases
Durability that space network is good and comfort level, it is ensured that the comfortableness of noise reduction and extend it simultaneously and use longevity when product uses
Life.The skin composition of the present invention selects thermoplastic elastomer, can reduce space network supportive owing to hardness is the lowest, need to enter
One step limits the preferred hardness scope (shore hardness as 80～98A) of thermoplastic elastomer, with reach best supportive and
Longer service life.
It addition, by controlling doughnut and the ratio of solid special fiber, it is achieved that changing indentation force deflection hardly
Under, adjustable go out noise reduction and there is the space network of different sense of touch, when using as buffering, support member, satisfied difference makes
The use requirement of user, strengthens the adaptive of application.
