Description
Technical field
The material belongs to fibrous material field, is a kind of one-time formed profiled composite fibre material of design and its preparation side
Method can be used as the seat core material of automobile, train, aircraft, steamer.
Background technology
The core material of seat generally uses sponge or foam, sponge-type is cheap, it is light it is soft, resilience is good, but it is thoroughly
Gas, heat dissipation performance are poor, the dirt that easily gets rusty, mould and acarid, and the problems such as cannot recycle and cause environmental pollution;Foam hinders
Combustion property is good, is easy to make, and is punched, but still faces and recycle difficult problem.
Since polyester and polyethylene belong to the non-polar conformations of macromolecular, crystallinity is high, is free of hydrophilic radical, hydrophily
It is poor, and fibre cohesion is big, when Through-Air Thermal Bonded Nonwovens being caused to comb networking, card doffer's needle cloth easily winds fiber, production
Quality is greatly affected, and can not achieve into the ES fibers of helical structure substantially.Germany, Japan and other countries have attempted to by
ES fibrous materials fail as core material because ES fibers are without legal type.
Invention content
In view of the above shortcoming, the present invention provides a kind of one-time formed profiled composite fibre materials, prepare work
Skill is simple and practical, and there are no three waste discharge, no glue, formaldehydeless generations in production process.
In order to achieve the above object, present invention employs following technical schemes:First by a variety of different fibers individually with
It after ES fibers are by mechanical carding, then is sufficiently mixed by strength, the fiber mixed is made by spherical, S types etc. by machine
Structural features comb the ES fibers of 2~3cm in mould inside upper and lower surface first, then by the method for increasing material manufacturing, will be aforementioned
The special die with hole pattern is added in structural member layer by layer, is moderately pressurizeed by gland, then punctured through hot wind so that material fully by
Heat makes the ES fibrous outers in material melt, and makes to form spot bonding between fiber, ultimately form internal porous gap, it is multi-level, have
The specific shape structure of elasticity.
The preparation method includes the following steps:The fiber material is PET Hollow fiber, ES fibers, carbon fiber, aramid fiber.
By weight percentage:Different fiber material are mixed in a certain ratio, ES fibers 30~50%, aramid fiber 10~20%,
Carbon fiber 30~50%, PET Hollow fiber 10~20%.
The ES fibers are a kind of composite fibres of skin-core structure, and cortex is polyethylene, and fusing point is 130 °C, and sandwich layer is poly-
Propylene, fusing point are 165 °C.
Have preparation process simple and practical using a kind of macromolecule composite self-adhering fiber prepared by aforementioned preparation process, once
Labour is saved in molding, does not have to glue and bonds, and so that formation thermal bond points between ES fibers and other fibers is bonded using heating, no
Containing formaldehyde and harmful substance, in manufacturing process, the generation of no exhaust gas, waste water, waste material.
Description of the drawings
Fig. 1 is Product Rendering.
Specific implementation mode
Description is further explained to the present invention with specific implementation mode below in conjunction with the accompanying drawings.
Embodiment 1
It is as follows to prepare a kind of backrest core material concrete technology of automotive seat,
It is 30% ES fibers, 20% PET Hollow fiber, 20% aramid fiber and 30% carbon fiber to take by weight percentage, through at the beginning of machinery
Step combs mixing, is blown into container, is sufficiently mixed in a reservoir by strength, and mixing is complete, machined, and spherical, S is made
The structural features of type etc..
50% ES fibers and 50% carbon fiber are sufficiently mixed into cotton-shaped thin layer through carding machine, and are layered on mold or more two
Partial inside.
The automotive seat core material mold with hole pattern is added in these flocculent structure parts made, mold is divided into two up and down
Point, after having filled, two parts are combined, then are punctured through hot wind so that internal all materials are fully heated, make the ES in material
Fibrous outer melts, and forms spot bonding between fiber, and being finally made inside has gap, multi-level, flexible specific shape knot
Structure external form.
Embodiment 2
Prepare it is a kind of as follows with the cushion core material concrete technology of automotive seat,
Preparation process with embodiment 1, unlike mould therefor it is different, being finally made inside has gap, multi-level, flexible
Train chair core material.
