Abstract
The invention discloses a dual-purpose double-layered hollow-core composite monofilament and a manufacturing method and application thereof. The monofilament comprises an outer surface layer and an inner core layer, wherein the outer surface layer coats the surface of the inner core layer; the inner core layer is of a hollow-core pipe structure; the inner core layer is a high-melting-point inner core layer made from a PP, PET or TPU or TPEE material; the outer surface layer is a low-melting-point outer surface layer made from a PE or PP or POE or TPU or TPEE material; and the melting point of the high-melting-point inner core layer is higher than the melting point of the low-melting-point outer surface layer. The cellosilk is of a hollow-core inner core structure, so that the double-layered cellosilk is stronger in porosity and capillary water absorption effect, and has better water guiding, water absorbing and filtering performances. When the monofilament is used for manufacturing a fiber pen point, the inner structure can enable printing ink to absorb water more smoothly; and when the monofilament is used for filter tips of cigarettes, the smoke penetrability is higher.

Step 3：Inner sandwich layer single fiber and extexine single fiber are combined into the fiber with double-decker at spinneret
Silk, the extexine is coated on inner sandwich layer outer surface, is drawn by hauling machine after double layer fibre silk cooling, will be double-deck fine
Dimension silk moves required length and diameter to；
Step 4：Double layer fibre silk is carried out by elasticizer again plus bullet forms pore and the more preferable DTY of bulkiness by fiber
Filament；
The present patent application also relates to one kind and is making fiber nib, the rod that absorbs water, filtering using double-deck hollow composite monofilament
Application in rod.
Compared with prior art, the beneficial effects of the invention are as follows：Filament uses the core arrangement of hollow so that double-deck fine
Dimension silk has stronger porosity and wicking ability, has more preferable water guide, water suction, strainability, for being fabricated to fibre
During dimension nib, it is more smooth that its internal structure can allow ink to absorb water, and in terms of for cigarette filter, can also cause smog penetrability
It is stronger, while composite monofilament is made of double-deck inside and outside low melting material high, can pass through in subsequent production, as needed
Mode of heating, the extexine of low melting point is melted, and dystectic inner sandwich layer is insoluble, the physical effect that extexine dissolving is produced
The monofilament of many only remaining inner sandwich layers can be bonded to each other, this production method has prevented glue and opened oil completely
The use of water, will not produce unnecessary impurity so that later product will not produce chemical substance, no matter in use still
In the removal process in later stage, all without any pollution of generation so that product will be as a kind of free of contamination product of environment-friendly and green.
