Description
Technical field
The invention belongs to textile technology fields, and in particular to a kind of different dye cool feeling composite fibre of one-step method pattern and its preparation
Method.
Background technique
With the continuous improvement of modern life level, people are also higher and higher to the pursuit of life comfort, and pursue clothing
Comfort and it is functional already become a kind of fashion, especially hot summer, everybody wishes to wear more clear naturally
It is refreshing, more pleasantly cool.In addition, environmentally friendly, low-carbon economy garment material is also recognized by people extensively in terms of environmental protection
It can.Therefore, the various functionality that can keep cooling feeling take fiber and its products and come into being, not only can be in sweltering heat
Summer brings nice and cool sense comfortable and easy to wear, it might even be possible to not need to obtain nice and cool sense by too low air-conditioner temperature
Feel, achievees the effect that low-carbon environment-friendly in a sense.Currently, cool fiber has been increasingly becoming the hot spot of chemical fibre industry research.
The cool fiber occurred in the market is mainly the following.The first, is designed by unique cross sectional shape, as in
Blank pipe shape, surface groove structures, cross structure etc. make fiber have " capillary effect ", strengthen radiating rate, and it is excellent to assign fabric
Different perspiration discharging performance can rapidly be transmitted to fabric surface with body surface sweat when human contact and evaporate, therefore generate
Nice and cool feeling.Second, it is that fiber is spun into using bibulous polymer (such as polyvinyl alcohol, PA6), makes fiber
It inhales, moisture releasing ability and speed improve, the feeling for keeping human body generation nice and cool by the thermally conductive and evaporative heat loss of moisture.But both the above
Fiber only has single heating conduction or perspiration discharging performance, is unable to reach ideal cool and comfortable sense.The third, is in the fibre
The biggish nanoscale minerals of thermal coefficient, such as mica powder, jade powder, borneol substance are added, to promote the thermally conductive of fiber
Performance is nice and cool to achieve the purpose that, such cool fiber is that one of the most common type, usual binding fiber abnormal shapeization design in the market,
Make fiber while there is good heating conduction and moisture absorbing and sweat releasing performance.But such fiber needs to add during preparation
The cool feeling function powder of Ghana's meter level, and nanoscale cool feeling function powder is easily reunited in a polymer matrix, can not be dispersed
Uniformly, increase lousiness, the broken end in the spinning process of fiber, the spinning property of fiber is decreased obviously, physics, machinery to fiber
Performance has a adverse impact.In addition, cool feeling function powder spreads out in a polymer matrix, and additive amount is very
Few, generally in 1%-5% or so, the more difficult formation of thermal conducting path, cool feeling effect is very limited.
In view of the above shortcomings of the prior art, therefore the application is proposed.
Summary of the invention
The primary purpose of the present invention is that providing a kind of different dye cool feeling composite fibre of one-step method pattern, the one-step method pattern is different
Dye cool feeling composite fibre has preferable moisture absorption sweat discharging functions and can rapidly conduct heat, keeps sweat or moisture fast
It is conducted fastly to the surface of fabric and evaporation, brings preferable nice and cool, dry feeling by relaxing for clothing dress can be significantly improved
Appropriateness, particularly suitable for preparation summer clothing or other textile fabrics.
The present invention reaches the beneficial effect to solve the deficiencies in the prior art, the technical solution of use it is basic
Thinking is as follows:
A kind of different dye cool feeling composite fibre of one-step method pattern, the different dye cool feeling composite fibre of one-step method pattern have endless

The different dye cool feeling of any one one-step method pattern as described above is utilized another object of the present invention is to provide a kind of
The textile fabrics that nonwoven fiber complex obtains.
It is cool another object of the present invention is to provide a kind of any one different dye of one-step method pattern as described in above content
The preparation method of sensing composite fiber, including the following steps:
(1) first polymer slice and second polymer slice are fed in two screw extruders carry out melting modeling respectively
Change, then be delivered to same composite component respectively and spray forming, obtains spun filament；
(2) by the spun filament in step (1) through cooling, oil, drafting forming, be wound into cylinder to get.
Preferably, the first polymer in the step (1) is polyamide slice, and screw rod fusion plastification temperature is 253-
