Description
Technical field
The present invention relates to a kind of fibres in differentiation, and in particular to a kind of bicomponent composite fibre and preparation method thereof.
Background technique
There are many multiplicity for the coloring mode of fiber.From processing method, there are original liquid coloring and dyeing two ways.Stoste
Coloring is that coloured material is added during the spinning process, and coloured material is evenly distributed in entire matrix.Dyeing is then rear
Coloured material is added on fiber by special process in road, different dyestuffs and fiber have different coloring process.For example divide
Scattered dyestuff is entered using the gap of fiber；Reactive dye are that anti-life is reacted with the hydroxyl on cellulose fibre；Acid dyes is then
It is in conjunction with carrying out ionic bond with the amino on wool, nylon.These above-mentioned coloring modes, either original liquid coloring or rear road
Coloring, all inevitably will appear coloring material and falls off, migrates from fiber in use, to cause staining, discoloration, dirt
Situations such as dye, damage health.
Summary of the invention
To solve current traditional stains method, there are coloured materials to fall off from fiber in use, migrates, thus
Situations such as causing staining, discoloration, pollution, damage health, the invention proposes a kind of bicomponent composite fibre and preparation method thereof,
Efficiently solving the problems, such as colored fibre, coloured material falls off and fades in use, and preparation method is simple.
The present invention is achieved by the following technical solutions: a kind of bicomponent composite fibre section is skin-core structure, by skin
Layer is made with the sandwich layer containing functional material through two-component composite spinning.
The mass ratio of the cortex and sandwich layer is 15-30:70-85.Coloured material is present in sandwich layer, skin quality accounting
Cannot be too high, otherwise color can not penetrate cortex, be unfavorable for sandwich layer colour developing.
The sandwich layer is mixed by functional material and core material.The functional material includes coloured material, also
Including matte powder, magnetic powder.
Sandwich layer is only added in functional material, and coloured material is not added in cortex, plays closing package action, prevents coloring material from escaping.
A kind of bicomponent composite fibre, coloured material are confined to sandwich layer, and there is no migration, cortex is free of coloring material.It should
Coloured composite fibre can be effectively prevented coloring material and escape in use, to improve the color fastness of colored fibre and make
With safety.
Core material include polyester, modified poly ester, polypropylene, modified polypropene, polyamide, modified polyamide, polyethylene,
Modified poly ethylene.
The coloured material, including inorganic pigment and organic dyestuff.Since organic dye molecule is easy migration, dissolution,
It is added to and is more easier to escape in fiber, preferably, coloured material is selected from inorganic pigment.
Cortex includes polyester, modified poly ester, polypropylene, modified polypropene, polyamide, modified polyamide, polyethylene, modification
Polyethylene, and coloring material is zero.
In preparation process, if cortex contains a small amount of matte powder, although can also develop the color, color can become dim.Make
To be preferred, the cortical material is to have light transparent materials, and wherein delustring powder content is zero.It is more conducive to color transmission in this way
Cortex.
In preparation process, if cortex and sandwich layer use compatible material, although during the spinning process, coloring material may be sent out
Raw migration, but to improving the color fastness of fiber, and have and greatly improve, preferably, the cortical material and sandwich layer material
Material be it is mutual exclusive, before being beneficial to prevent in spinning process strand solidification in this way, coloured material moves to cortex from sandwich layer.
A kind of preparation method of bicomponent composite fibre is following steps:
(1) coloring material and core material are mixed and made into sandwich layer；
(2) bicomponent composite fibre is prepared using core/sheath bicomponent composite spinning technology in sandwich layer and cortex.
Cortex and sandwich layer are melted by screw rod specifically, then melted the spinning of two kinds of different chemical compositions by metering pump
Body, is delivered to filament spinning component, while the distribution system and spinneret of skin-core structure can be prepared by one, enter spinneret orifice it
Before, two kinds of ingredients are separated from each other, and are not mixed mutually, and in the moment for entering spinneret orifice, two kinds of melt contacts simultaneously spray, and then solidification is viscous
Piece strand with skin-core structure of synthesis.
During the spinning process, by controlling the spinning temperature of sandwich layer and cortex, melt viscosity and melt are adjusted from spinneret orifice
After ejection, cooling wind temperature, humidity, wind speed etc. are adjusted, coloured material is beneficial to prevent and migrates from sandwich layer to cortex.
The bicomponent composite fibre can be processed into short fibre, drafting silk, preoriented yarn by different manufacturing procedures,
Preoriented yarn can be further processed into stretch textured yarn.
Compared with prior art, the beneficial effects of the present invention are: the bicomponent composite fibre effectively prevent coloring material
Material escapes in use, to improve the color fastness of colored fibre and using safe.
