Description
Technical field
The invention belongs to terylene composite fibre field, particularly curling composite fibre of outage moisture absorption and preparation method thereof in a kind of bi-component.
Background technology
Terylene is the very many a kind of chemical fiber garment raw material of fabric in daily life, the maximum advantage of its fabric is that wrinkle resistance and conformality are fine, but its sucting wet air permeability is poor, and it is airtight, non-hygroscopic that fabric makes garment material, and easily because friction produces electrostatic, wear sultry especially uncomfortable.In recent years, along with the development of demand of articles for use is spun by family, consumption increases rapidly, and China has become the maximum production of terylene chemical fibre and demand country, to produce and the development of demand and people pursue and wear pursuit that is attractive in appearance, comfort level and there is great paradox, govern further developing of terylene chemical fibre.
Summary of the invention
Technical problem to be solved by this invention is to provide curling composite fibre of outage moisture absorption and preparation method thereof in a kind of bi-component, and this composite fibre has good simulate wool effect, and has that good moisture absorption is ventilative, antistatic behaviour; Preparation method only need transform at existing equipment, greatly can improve the application performance of terylene, expand its application space, enrich and optimize garment material, have significant economic benefit and social benefit.
The curling composite fibre of outage moisture absorption in a kind of bi-component of the present invention, described composite fibre is adopted the terylene of mass ratio 50:50-70:30 and bio-based polyamide fibre 56 and adds adhesive and obtained by circle hollow 2C spinneret orifice.
Xeothermic, the boiling water shrinkage difference of described terylene and bio-based polyamide fibre 56 are all greater than 10%.In process, because of generation difference in shrinkage of being heated, finished product strand produces large waveform three-dimensional crimp construction fabric and shakes grain process through dyeing and finishing humid heat treatment and xeothermic rotation, produces curling tufting structure attractive in appearance.
The addition of described adhesive is the 2-6% of gross mass.Adhesive is blended in terylene and the section of full bio-based polyamide fibre 56 according to the ratio of 2-6% respectively, be melted into blend melt together, adhesive is with the group reacted with polyamide fibre 56 and terylene, in two component contacts faces two component good bond, avoid because of terylene and polyamide fibre poor compatibility, fiber stretches at aft-loaded airfoil, by hyther time, because bi-component difference in shrinkage interface produces shearing force two-phase laminated flow, thus fiber properties can be deteriorated or disappear.
Described round hollow 2C spinneret orifice is made up of the first spinneret orifice of two C word structures and the second spinneret orifice, first spinneret orifice and the distribution of the second spinneret orifice opposed juxtaposition, first contact interface of contact position is identical with the second contact interface, the first spinneret orifice and the second spinneret orifice respectively with the corresponding connection of pod apertures in the pod apertures on the polyester derivative chute on melt distribution plate and polyamide fibre 56 guiding gutter.Ensure to wash brocade and the polyamide fibre 56 single C part distributing binder arranged side by side respectively by spinneret orifice.Adopt lateral blowing cooling spinning during spinning, as shown in Figure 2, ensure that blowing direction is vertical with the symmetry axis of 2C spinneret orifice, terylene component Parts is near blowing window in the installation of spinnerets.Make bi-component Asymmetrical cooling, terylene cooling velocity is fast, increases xeothermic, the damp and hot inotropic difference of bi-component, increases thread crimping performance and curling stability.The ratio of the width of the first spinneret orifice and the second spinneret orifice vertical direction and the width of horizontal direction is 2:3-1:2, two single C spinneret orifice walls can be identical, also can be different curve, said structure ensure that strand is subject to easily occur curling and just have the effect keeping curly form stability by humid heat treatment.
The area ratio of described first spinneret orifice and the second spinneret orifice is 50:50-70:30.
The preparation method of the curling composite fibre of outage moisture absorption in a kind of bi-component of the present invention, comprising:
On two component combined spinning machine, adopt circle hollow 2C spinneret orifice, adopt the terylene of mass ratio 50:50-70:30 and bio-based polyamide fibre 56 and add adhesive, carrying out spinning and namely obtain the curling composite fibre of outage moisture absorption in bi-component; Wherein, the screw rod melting of bio-based polyamide fibre 56 component system and spinning temperature are than the temperature height 5-10 DEG C of terylene system, and polyamide fibre 56 fusing point, a little more than terylene, improves spinning temperature, to ensure its rheological property.
Full-drawn yarn FDY, draw false twisting textured filament DTY or short fiber are made in described spinning.
The described technological parameter making full-drawn yarn FDY or short fiber is: stretcher strain temperature 100-120 DEG C, setting temperature 120-140 DEG C; The technological parameter making draw false twisting textured filament DTY is: total drawing ratio draw ratio 3.2-4.0, draw false twisting distortion speed ratio 1.2-1.4, false twist texturing temperature 180-200 DEG C, false twisting setting temperature 130-150 DEG C.
beneficial effect
The present invention has good simulate wool effect, and has that good moisture absorption is ventilative, antistatic behaviour, and fabric shakes grain process through dyeing and finishing humid heat treatment and xeothermic rotation, has the curling tufting structure attractive in appearance of high imitative wool, and has fine snugness of fit; Preparation method only need transform at existing equipment, greatly can improve the application performance of terylene, expand its application space, enrich and optimize garment material, have significant economic benefit and social benefit.
