Description
Technical field
The present invention relates to a kind of blended looping composite yarns of the wear-resisting antistatic of high-strength fire-retarding anti-dropping and preparation method thereof, belong to
In field of textiles.
Background technique
In flame-resistant garment, material of main part usually mostly uses aramid fiber, and aramid fiber is the very mature height of current technique
Performance fibers, its chemical name is poly (being commonly called as aramid fiber 1313) and poly(p-phenylene terephthalamide)
(being commonly called as Fanglun l414), both fibers all have good heat-resisting quantity and anti-flammability, but the glass transition temperature of aramid fiber
Height, dyeing is difficult, and water imbibition is also poor, therefore kevlar fabric is difficult to possess the color of higher quality, it is difficult to which camouflage printing meets
Bu Liao army camouflage painting demand；Electrostatic problem, cannot be in gunpowder processing factory, inflammable powder processing factory etc. to anti-also than more prominent
The demanding occasion of static behaviour uses.
Aramid fiber is generally also mostly used in operation fabric, the amount ratio of aramid fiber accounts in U.S. army's earlier generations operation fabric
50% or more, due to aramid fiber dyeing difficulty, causes that the camouflage printing of entire operation fabric is difficult, intensity is low, comfort is poor etc. and ask
Topic.The fire-retardant operation fabric of U.S. army's latest generation uses Fanglun l414/anti-flaming viscose/high-strength nylon66 fiber (25:65；10) three kinds of fibers
It is blended to form, its advantage is that fire-retardant, anti-dropping, camouflage printing are relatively good, wearability is appropriate, comfortable；But it still remains durable
The problems such as property is poor, intensity is low and price is high, and 25% Fanglun l414 fiber makes fabric that must use a part of pigment printing, causes
Feel difference problem still remains.How in retention property, the content of high-performance fiber is further decreased, and then improve face
Comfort, camouflage printing of material etc. are always research puzzle.
Summary of the invention
The object of the present invention is to provide a kind of blended looping composite yarn of wear-resisting antistatic of high-strength fire-retarding anti-dropping and its systems
