Description
Technical field
The present invention relates to the technical field of synthetic textile fibre, specifically a kind of manufacture of flame retardant type zein fiber long filament
Method.
Background technique
It being counted according to related data, 1/3 fire is caused by being ignited rear fire spreading as textile, in order to
The generation countries in the world for reducing fire all are being dedicated to studying and using flame retardant textiles.Zein fiber is the one of acid fiber by polylactic
Kind, it uses the plant resources of natural reproducible for raw material, reduces the dependence to conventional petroleum resource, meeting international community can
The requirement of sustainable development, while having the characteristics that complete natural circulation type all and energy biological decomposition again, so obtaining international textile industry
Extensive attention.For acid fiber by polylactic as a kind of kinds of fibers that comparison is new, there are many product advantage, but fail largely to answer always
With main cause is to produce and still having many problems to be solved using upper.Such as the elastic force problem of fabric.Due to
The fusing point of zein fiber be far below polyester fiber and nylon fibre, production and use process in if more than 170 DEG C zein fibers
Melting completely, but fabric will have biggish elastic force that must use spandex, and the setting temperature of spandex just can ensure that at 170 DEG C or more
The dimensional stability of finished textile product.The low melting point of zein fiber causes to be difficult to produce elastic force at present and dimensional stability is all preferable
Zein fiber elastic fabric；In addition the anti-fluffing and anti-pilling performance of current zein fiber fabric is mostly poor, and generally only 2.5
~ 3 grades, this is that the inadequate natural endowment of zein fiber causes, and still fails to reach 3 grades or more of pilling resistance index so far, but
For consumers, product has just been used with regard to pilling, this is the hard defects of product；And the flame retardant property of zein fiber fabric
Still not ideal enough, it is unable to reach chance open fire and does not burn, leaves the requirement extinguished rapidly after open fire.
Summary of the invention
It is big, non-ignitable with soft feel, good anti-flammability, chance open fire that the object of the present invention is to provide a kind of elastic force
Burn, leave the manufacturing method of the flame retardant type zein fiber long filament extinguished rapidly after open fire.
In order to achieve the above objectives, the present invention adopts the following technical scheme that:

It carrying out melt spinning and obtains preorientation fibre bundle, spinning temperature is between 200-220 degrees Celsius, spinning specification: 75D-300D,
Spinneret hole count: -288 hole of 36 hole；
C) add bullet, above-mentioned preorientation fibre bundle is passed through into temperature with 400-500 meters of speed per minute as 105-115 degrees Celsius
High temperature heat radiation pipeline center, the length of high temperature heat radiation pipeline bringing-up section is 1.5-2 meters, utilizes high temperature heat radiation pipeline
The different rotating speeds of conducting wire roller of rear and front end guidance preorientation fibre bundle the preorientation fibre bundle of heating is elongated
1.5-1.6 again；It handled after preorientation fibre bundle cooling after elongation by scroll tube, assign its certain bulkiness and bullet
Property, obtain elastomeric fiber strands；The subsequent elastomeric fiber strands are imported into and by the centers of calibration tube, by being mounted on calibration tube
Air current spray nozzle on side wall, to elastomeric fiber strands injection pulse air-flow, forms interval under certain air pressure on tow
Fluffy section and close section being arranged, the air pressure of air current spray nozzle are 1.5 kilograms；The elastomeric fiber strands are then directed into and pass through
The center for the low-temperature heat radiation sizing pipeline that temperature is 100-110 degrees Celsius, gives the certain contraction of tow and internal stresses release,
Make tow that there is certain dimensional stability and by thermal stability, obtain can weaving flame retardant type zein fiber long filament.
The fire retardant is phosphorus flame retardant.
