Abstract
The present invention relates to a non-woven fabric cushion and its production method. Said cushion includes external wrapper and its internal elastic body, and is characterized by that said elastic body is made up by using two kinds of chemical fibres with different melting point, and its production process includes the following steps: proportinoing them, carding, mixing, fleece forming, placing them into mould and preforming, using hot air to heat and making fibre with low melting point gel, forming in mould, cooling so as to obtain the invented fibre elastic body. Said invention cushion is high in strength, good in gas permeability and elasticity and long in service life, etc.
Description
Technical field
The present invention relates to seat cushion and production method thereof, particularly a kind of non-weaving cloth fiber seat cushion and manufacture method thereof that is applicable to that automobile etc. is located.
Background technology
At present, the inner material that adopts of seat cushion locating to use such as automobile is polyurethane foam.The intensity of this seat cushion is lower, loss of properties on aging, and permeability is poor, and service life is short.Polyurethane foam in it pernicious gas that all can volatilize in producing and using, contaminated environment causes bigger harm to people healthy.
Summary of the invention
The object of the present invention is to provide long, free from environmental pollution non-weaving cloth fibrous elasticity seat cushion of a kind of intensity height, ageing-resistant, life-span and its manufacture method.
In order to realize purpose of the present invention, intend taking following technical scheme:
This seat cushion includes the elastomer of exoperidium and Qi Nei, and unique distinction is: elastomer is to be made by the chemical fibre of different melting points.
Above-mentioned chemical fibre is selected high resiliency for use, high is curled, dystectic polyster fibre and low melting point bi-component composite fiber; The two shared percentage by weight is respectively 75～90% and 10～25%.
Above-mentioned selected raw material is respectively: 15% thick 45D, the polyester staple fiber of long 65mm; 50% thick 30D, the polyester staple fiber of long 51mm; 15% thick 15D, the doughnut of long 65mm; Two component low-melting fibers of 20% thick 4D or 7D, long 51mm.
The manufacture method main technique of this seat cushion is: choose the chemical fibre of two class different melting points according to the above ratio, be mixed into net through combing; Preformed in being metered into mould; Make the low-melting fiber gel through the hot blast heating; At in-mold molding after cooling promptly is fixed to the fibrous elasticity body; Its outer setting foreskin promptly becomes seat cushion.
The invention has the advantages that and broken through the pattern that seat cushion that automobile for a long time etc. locates adopts polyurethane foam to make, overcome the drawback that polyurethane foamed material exists, brought into play the strong point of non-weaving cloth chemical fibre material, make the intensity of its seat cushion good, permeability is good, good springiness, long service life, particularly produce and use in the pernicious gas that can not volatilize, safeguarded that surrounding enviroment and people's is healthy.
The specific embodiment
Enforcement of the present invention is at first selected materials by aforementioned ratio, and each raw material is mixed into technologies such as net, preformed, heating gel processing, moulding, cooling and shaping, system foreskin and becomes through combing has elastomeric non-weaving cloth chemical fibre seat cushion.Now be described as follows with specific embodiment:
At first choose three kinds of higher chemical fibres of fusing point (its melting temperature is 180 ℃～220 ℃), they are respectively: the polyester staple fiber of thick 45D, long 65mm, and its rigidity is better, and percentage by weight is 15%; The high crimped polyester short fiber of thick 30D, long 51mm, percentage by weight is 50%; The three-dimensional crimp doughnut of thick 15D, long 65mm, percentage by weight is 15%.In addition, choose the lower chemical fibre of a kind of fusing point (its melting temperature is 120 ℃～140 ℃) again, concrete raw material is the bi-component composite fiber of thick 4D or 7D, long 51mm, and percentage by weight is 20%.Above-mentioned each raw material is mixed into net after be metered into preformed in the mould through combing; Make the low-melting fiber gel through the hot blast heating, its concrete mode of heating can adopt direct-fired heating of No. zero diesel oil or heating conduction oil to dispel the heat through fin, the heat delivery that produces is arrived heat accumulation indoor (about 150 ℃ of room temperature), utilize blower fan that heat is blown to heat in the mould again its fiber gel is got final product; Behind in-mold molding, promptly be fixed to the fibrous elasticity body through cooling (adopting blower fan under 5 ℃～15 ℃ temperature, to blow about 1 minute); Its elastomeric outer be provided with foreskin this seat cushion.
