Description
Technical field
The invention belongs to composite fibre preparation technical fields, and in particular to a kind of health compound fibre of high fluffy PE-PET
Dimension and preparation method thereof.
Background technique
PE(polyethylene)/PET(polyethylene terephthalate), PE(polyethylene)/PP(polypropylene) etc. bi-components it is multiple
Since cortex has low melting point, sandwich layer has higher melt, can form Through-Air Thermal Bonded Nonwovens by hot blast adhesion condensating fiber.It is this
Bicomponent composite fibre is answered due to not using adhesive and soft comfortable in hygienic materials such as paper diaper, sanitary napkins extensively
With.
The high fluffy of non-woven cloth assigns the fabulous comfort of hygienic material, high drain.The conventional compound fibre of PE/PP
Arranged side by side, core-skin bias mode can be used on cross section structure, utilized two kinds of material stresses due to the compatibility of PE and PP for dimension
With the disequilibrium of heat transfer, to obtain higher bulkiness.But due to the industrial scale of PET and it is recyclable the features such as, PET
There is biggish cost advantage than PP, at present mainstream of the PE/PET as material in hygienic bicomponent fibre.
Application No. is the patents of CN201410481816.0 to disclose a kind of pleasant type modified polyester complex fiber that keeps warm
Preparation method, the preparation method by the polyester master particle containing tourmaline powder and polyester slice blend melt spinning, pass through first
First abnormal-shape spinneret plate produces a kind of functional hollow polyester preoriented yarn POY；Again by Modified polyester chips through melt spinning,
A kind of cross polyester preoriented yarn POY is produced by the second abnormal-shape spinneret plate；Finally by functional hollow polyester preorientation
It is multiple to obtain one kind pleasant type modified poly ester that keeps warm through elasticizer false twisting combined processing by silk POY and cross polyester preoriented yarn POY
Condensating fiber.But due to PE/PET fiber, its two kinds of components are incompatible, eccentric or total using arranged side by side or core-skin such as on cross section structure
The mode that consolute melts, influences the comfort of rear road non-woven cloth processing and hygienic material at phenomena such as easily causing fiber decortication separation.
Summary of the invention
