Description
Technical field
The present invention relates to a kind of synthetic fibers and preparation method thereof, more particularly to a kind of conductive spandex fibre and its preparation side
Method.
Background technology
With the fast development of synthetic fibers, the shared ratio in chemical fibre application of synthetic fibers is increasing.But
Synthetic fibers have a problem that in actual applications, are exactly easily to gather electrostatic.Electrostatic can cause textile using process
Middle absorption dust, pilling, clothes tangle human body and produce adhesion sense of discomfort.Spandex scientific name polyurethane fiber, it is fine as synthesis
One kind of dimension, with excellent elastic performance, is described as " monosodium glutamate " of textile, adds a small amount of spandex can be significantly in fabric
The wearability of final products is improved, but spandex there is also accumulation electrostatic problem.
Conventional solution, is that a small amount of conductive fiber is added in fabric at present, can effectively solve synthetic fibers
Clothes easily produce the problem of electrostatic, and this method is mostly, in weaving textile, conduction material to be added by warp-wise or broadwise
Material, makes fabric have antistatic property.
The patent of invention of Publication No. CN102560817A, discloses a kind of Comfortable functional wool-like casual fabric, its
It is characterised by：It is warp thread that warp-wise uses tencel, fine denier staple fiber, the scribbled of fine-denier wool fiber；Broadwise is former using A
Material and B raw materials, A raw materials are polyurethane covered yarn, and B raw materials are the modified yarn of wool type, specifically include cationic fiber, fine denier viscose fine
Dimension, conductive fiber.The invention " can be effectively antistatic " is recorded in its specification, but composite braided technical matters is complicated, to compiling
The equipment of knitting has higher requirements.
The content of the invention
It is an object of the invention to provide a kind of conductive spandex, the fabric containing spandex can be made to possess the same of excellent comfort property
When with good antistatic property.
The technical solution adopted for the present invention to solve the technical problems is：A kind of preparation method of conductive spandex fibre, its
It is characterised by：With reference to two kinds of technologies of dry spinning and melt spinning, comprise the following steps：
（1）Sandwich layer spandex fibre uses dry spinning technology, and dry spinning spandex stoste is prepared through polymerisation in solution, defeated by spinning pump
Go out；
（2）Cortex spandex fibre uses melt spinning technology, and conductive agglomerate cement-based powder material hopper is by screw extruder in melting
State；
（3）The dry spinning spandex stoste and conductive agglomerate, after mixing by composite spinneret；
（4）The dry spinning spandex stoste and conductive agglomerate, after going out composite spinneret, the cross air blasting crossed through high-temperature heating in path
By the DMAC dryings in solution, two kinds of polyurethane fibers are made firmly to be bonded together；
（5）The rolled machine coiling and molding of strand gone out behind path.
According to the product that a kind of preparation method of conductive spandex fibre is obtained, a kind of conductive spandex fibre, it is characterised in that：
The cross section of the conductive spandex fibre is circular, skin-core structure, and cortex is conductive polyurethane composition, and core is common polyurethane
Composition.
Further, the ratio shared by the cortex is 5 ~ 30%.
Further, the conductive agglomerate of the cortex is by being made after granulation by melt-spun polyurethane particle and conducting particles
, conducting particles is CNT or Graphene；Content of the conducting particles in conductive agglomerate is 10 ~ 40%.
The invention provides a kind of conductive spandex, certain proportion conduction is contained by adhering to one layer in the outside of dry spinning spandex
The melt spun spandex cortex of particle, makes polyurethane elastomeric fiber while high drawing, resilience high is kept with good electric conductivity
Energy.There is good antistatic property using the fabric of conductive spandex, with wide market prospects.By obtained in the method
Conductive spandex appearance color is in black, with good electric conductivity, in standard state：20 DEG C of temperature, the % of relative humidity 65, than
Resistance is in below 107 Ω cm.With excellent durability and stability, friction, bending and washing do not have to its electric conductivity
Have an impact.And in fabric of the production containing spandex material, the conductive spandex can be directly used, be not required to separately add conductive material,
Greatly reduce the process specifications of production.
