However, since the above-mentioned conventional skin material is made of materials having different physical properties, that is, polyester fiber and polyurethane foam, it is impossible to purely recover polyester by thermal decomposition of polyurethane when heat-treated for recycling.

That is the purpose.

ポリエステル樹脂層３によって接着されているものであ
る。The present invention will be described in detail below with reference to the drawings. As shown in FIG. 1, the composite skin material 1 of the present invention is a nonwoven fabric having a skin portion 2 of polyester fiber and a polyester fiber and having a thickness of 1 to 20 mm. 4 are bonded by a polyester resin layer 3 having air permeability.

ないものなどいずれの形態であってもよい。The skin portion 2 is made of polyester fiber,
This is for remelting and reuse. Therefore,
The non-woven fabric 4 and the resin 3 for adhesion must also be made of polyester resin. In addition, the polyester fiber as used herein is meant to include polyethylene terephthalate fiber, copolymerized polyester fiber, and polybutylene terephthalate fiber. Further, the form of the skin portion 2 may be any form such as a woven fabric, a knitted fabric, a raised fabric or a non-raised fabric.
【０００９】次に不織布４は、厚さが１〜２０ｍｍなけ

られないからである。もし、厚さが１ｍｍ未満であると
弾発力に乏しくなって風合的に好ましくない。他方、２
０ｍｍをこえると曲げ剛性が大きくなって風合を損ねる
ので望ましくない。Next, the nonwoven fabric 4 must have a thickness of 1 to 20 mm. This is because when it is used for automobile seats, etc., it cannot withstand resilience unless it has a certain thickness. If the thickness is less than 1 mm, the elasticity is poor and it is not preferable in terms of feeling. On the other hand, 2
If it exceeds 0 mm, the bending rigidity is increased and the texture is impaired, which is not desirable.
【００１０】厚さ１〜２０ｍｍの不織布４は、前述のよ

で構成されていなければならない。これは、リサイクル
のために再溶融するときに分解又は粘度特性の低下を惹
起させないためである。The non-woven fabric 4 having a thickness of 1 to 20 mm must be made of polyester fiber as the fibers constituting the skin portion 2 as described above. This is because it does not cause decomposition or deterioration of viscosity characteristics when remelting for recycling.

適である。The non-woven fabric 4 may be a single substance or one having a thickness as described above, but may be a laminated composite form. In any case, the density is 0.01-0.1 g
It is preferably in the range of / cm 3 . In addition, non-woven fabric 4
It is preferable that the thickness of the fibers constituting the fiber is 0.5 to 20 d.

ても通気性の妨げとならない形態で用いるのが好まし
い。Therefore, from this viewpoint, the polyester resin layer 3 is preferably used in the form of a breathable sheet. This is because the air permeability after adhesion is good, and since the penetration is less than when the liquid adhesive is used, the texture after adhesion is soft and good. For example,
It is preferable to use a woven fabric, a knitted fabric, a non-woven fabric, a perforated film or the like in a form that does not hinder the air permeability even after being bonded.

If it is less than 300 g / m 2 , wrinkles are likely to be formed, while if it exceeds 800 g / m 2 , bending rigidity becomes large and sitting comfort becomes unfavorable. From this meaning, 350-650 g /
The range of m 2 is more preferable.

り、純粋なポリエステルの回収を容易とする。When the composite skin material of the present invention is used as a skin material for automobile seats, etc., the skin is made of polyester fiber, so that the texture is good, and a non-woven fabric having a thickness of 1 to 20 mm is bonded by a breathable polyester resin layer. Therefore, the air permeability is also good. In addition, since the whole is polyester fiber or resin, it has the same physical properties and exhibits the same behavior when heat-treated for recycling, allowing recycling and facilitating recovery of pure polyester.
