CN104195673B(bi-component polyester composite fibre direct fabrics method and system), using bi-component PET.
Since above-mentioned bi-component composite fiber has good three-dimensional crimp performance, thus obtained extensively in knitting field
Application.But since the crimp radius of bicomponent composite fibre is relatively large, thus in the fiber crimp of certain length range
Quantity is restricted.Three component composite fibers are because crimp radius is significantly less than bicomponent composite fibre, thus in certain length model
Fiber crimp quantity in enclosing is significantly higher than bicomponent composite fibre, to keep bicomponent composite fibre compound with three components
The elasticity stood out from one's fellows and flexibility of fiber compare favourably.But during preparing three component composite fibres, the compound fibre of three components
Consistency problem between dimension melt significantly protrudes from the compatibility between bicomponent composite fibre melt, that is to say, that component
The more, consistency problem is more prominent, and technique controlling difficulty is accordingly bigger, otherwise will affect the quality of three component composite fibres.Tool
It says to body, if the compatibility of three component composite fibres is short of, after the melt of each component is compound, in the vertical of single fiber
Can be generated to direction and the phenomenon that bifurcated occur by can not effectively bond caused by between different melt, thus in rear road drawing-off or
Lousiness, broken end are led to the problem of during person's others textile process, the quality of three component composite fibres is caused to be unable to reach industry
Expection, or even be difficult to be acceptable to the market.
Equally visible all technical information about three component composite fibres in disclosed Chinese patent literature, such as
CN1164810C(polyamide fine fibre and preparation method thereof), CN1185377C(polyaniline/polyamide conductive fibers and its preparation
Method), a kind of three-component fiber of CN101892536B(is blended and its manufacturing process), a kind of multiple groups part of CN101768796B(it is multiple
Close eccentric fiber and preparation method thereof), a kind of multi-component compound eccentric fiber of CN101798713B(and preparation method thereof),
A kind of preparation method of meta-aramid fibers of CN103233292B() and a kind of high anti pilling of CN105908268B(and high abrasion
Three component composite fibres and preparation method thereof), etc..
It is considered from the angle that a workman must first sharpen his tools if he is to do his work well, to prepare three component composite fibres, then three components are multiple
Condensating fiber device for spinning it is structurally reasonable whether be overlook either of the two an important factor for because the characteristic of different fibrous raw materials is viscous
Degree is different the adaptability of temperature etc. of screw rod melting extrusion, however China and foreign countries' patent disclosed so far and it is non-specially
All technical information with three component composite fibre associated equipments of preparation, technical solution described below are showed no in sharp document
It generates in this background.
