The fibroplastic layer of fiber number and by have the fibroplastic layer of the filament denier of 2.5~15 daniers carry out lamination form
's.But in the filling cotton recorded in patent document 2, only by the layer of the small fiber of filament denier (net (web)) and single fiber
The layer (net) of the big fiber of fiber number has carried out lamination, and the fiber of different fiber numbers is not wound mutually, thus even with two kinds
Fiber with different fiber numbers, also almost without the effect of raising bulkiness.Herein, " net " is that fiber is instigated to be overlapped and form piece
The structure of shape.
In addition, propose a kind of filling cotton in patent document 3, it by filament denier is more than 0.5dtex and small to be
Staple fiber, filament denier in 3dtex are that 5dtex is less than doughnut, the filament denier of 10dtex
10dtex is heat bondings of the 1dtex less than 5dtex less than the doughnut and filament denier of 30dtex
Property staple fiber mixes.In the filling cotton of patent document 3, using filament denier for 0.5dtex less than
The staple fiber of 3dtex assigns heat insulating ability, and heat insulating ability and bulkiness are assigned using the staple fiber that filament denier is more than 5dtex.
But even filling cotton recorded in patent document 3, bulkiness is still insufficient.
A kind of pearl cotton is proposed in patent document 4, is filament denier for 1.1~15.0dtex, fiber a length of 3
The average diameter that the fiber of~64mm is wound mutually is the pearl cotton of 3~10mm, in the pearl cotton, polyester fiber with different melting point
Include two or more heat-bondable fibres.
In the pearl cotton of patent document 4, by the way that fiber is partly bonded to maintain with heat-bondable fibre each other
Shape prevents the bias of cotton (piece posts り).But even pearl cotton recorded in patent document 4, bulkiness, heat insulating ability are still not
Fully.
