Description
Technical field
The present invention relates to the technical field of synthetic textile fibre, specifically a kind of system of coloured anti-bacterial zein fiber long filament
Make method.
Background technique
Polylactic acid is also referred to as polylactide, belongs to polyester family.Polylactic acid is obtained with the main polymerizable raw material of lactic acid
Polymer, raw material sources are abundant and can regenerate.The production process of polylactic acid is pollution-free, and product can be biodegradable,
It realizes circulation in nature, therefore is ideal Green Polymer Material.Acid fiber by polylactic is as a kind of fibre that comparison is new
Type is tieed up, there are many product advantage, but fail largely to apply always, and main cause is to produce and still having much using upper
Problem to be solved.Such as the elastic force problem of fabric.Zein fiber is also known as acid fiber by polylactic (PLA), is with corn, wheat etc.
Starch is raw material, fermented to be converted to that lactic acid is aggregated again to be spinned, and belongs to very environmentally friendly biodegradable fiber, by
In zein fiber fusing point at 165 ~ 170 DEG C, far below the fusing point of fusing point (252 DEG C or so) and nylon fibre of polyester fiber
(220 DEG C or so), production and the melting completely if more than 170 DEG C zein fibers in use process, but fabric will have biggish bullet
Power must use spandex, and the setting temperature of spandex just can ensure that the dimensional stability of finished textile product at 170 DEG C or more.Corn is fine
The low melting point of dimension causes to be difficult to produce all preferable zein fiber elastic fabric of elastic force and dimensional stability at present；In addition at present
The anti-fluffing and anti-pilling performance of zein fiber fabric is mostly poor, and generally only 2.5 ~ 3 grades, this is the inadequate natural endowment of zein fiber
It causes, still fails to reach 3 grades or more of pilling resistance index so far, but for consumers, product is just using with regard to rising
Hair pilling, this is the hard defects of product；And the color of zein fiber fabric is also not gorgeous enough, dyeing in production process
Compare difficult grasp.These problems always affect the fast development of zein fiber industry.
Summary of the invention
That the object of the present invention is to provide a kind of elastic force is big, beautiful in colour, with soft feel, good comfort and folding
The manufacturing method of the coloured anti-bacterial deodorization zein fiber long filament of wrinkle recovery.
In order to achieve the above objectives, the present invention adopts the following technical scheme that:
A kind of manufacturing method of coloured anti-bacterial zein fiber long filament of the present invention, using following steps:
A) the drying of particle is put particles of polylactic acid, antibacterial matrices and Masterbatch into sufficiently dry in drying machine respectively；Wherein
Particles of polylactic acid is dry using drum dryer；Antibacterial matrices and Masterbatch are put hot air type baking oven into and are dried；Contained
Water is lower than the dry particle of 30ppm.
B) spinning, by after above-mentioned drying Masterbatch and antibacterial matrices respectively with the ratio of 1%-5% extruder type spinning machine spiral shell
Melt spinning is carried out in particles of polylactic acid after being mixed into drying before bar, between 200-220 degrees Celsius, spinning specification is temperature
75D-300D, spinneret hole count are -288 hole of 36 hole, obtain preorientation fibre bundle.
C) add bullet, it is 105-115 that above-mentioned preorientation fibre bundle, which is passed through temperature with 400-500 meters of speed per minute,
Degree Celsius high temperature heat radiation pipeline center, the length of high temperature heat radiation pipeline bringing-up section is 1.5-2 meter, utilizes high warm spoke
The different rotating speeds for penetrating the conducting wire roller of pipeline rear and front end guidance preorientation fibre bundle draw the preorientation fibre bundle of heating
It is 1.5-1.6 times long；It handled after fibre bundle cooling after elongation by scroll tube, assign its certain bulkiness and elasticity, obtained
To elastomeric fiber strands；The subsequent elastomeric fiber strands are imported into and by the centers of formed pipe, by being mounted on formed pipe side wall
On air current spray nozzle under certain air pressure to elastomeric fiber strands injection pulse air-flow, interval setting is formed on tow
Fluffy section and close section, last elastomeric fiber strands are imported into and pass through temperature as 100-110 degrees Celsius of low-temperature heat radiation
Be formed the center of pipeline, give the certain contraction of tow and internal stresses release, make tow have certain dimensional stability and by
Thermal stability, obtain can weaving coloured anti-bacterial zein fiber long filament.
Above-mentioned particles of polylactic acid is corn plant base polylactic acid particle, the antibacterial matrices be nano silver, nano zine oxide,
The particle of the mixture of one of nano cupric oxide, nano-titanium dioxide or several substances.
After adopting the above technical scheme, the production method production zein fiber long filament elastic force it is big, it is beautiful in colour it is colour-fast,
With soft feel, good comfort and crease recovery.It is provided simultaneously with excellent of both natural fiber and chemical fibre
Point.It is degradable, non-environmental-pollution problem；Elasticity is good, and not vulnerable to the influence of ultraviolet light；Anti pilling, easy dyeing, anti-flammability are hydrophilic
Property is good；Raw material comes from plant, the renewable circulation of resource.
Detailed description of the invention
