Description
Technical field
The invention belongs to textile technology field is and in particular to a kind of multicomponent fire resistance fibre produces ring ingot with polyamide fibre 66 blending
The methods and applications of yarn.
Background technology
Fire retardant protective clothing is one of kind of being most widely used in personal protective equipment, and fire retardant protective clothing principle is mainly
Take heat-insulated, reflection, absorb, the shielding action such as carbonization isolation, flame-retardant clothing protects labourer from the injury of naked light or thermal source.Resistance
Combustion clothes adopt special fabric, and in its fabric, fire resistance fibre makes the burning velocity of fiber significantly slow down, after burning things which may cause a fire disaster is removed certainly at once
Horizontal blanking, and combustion parts carbonize rapidly and do not produce melting, drippage or Durchgangshohle, and the time of giving people withdraws combustion site or takes off
The clothes burning with it, is reduced or avoided empyrosis, reaches the purpose of protection.
Contain high-temperature fibre in the fibre fractionation of fire retardant protective clothing fabric, high-strength low-ductility stretches ballistic fiber and anti-simultaneously
The high-tech such as electrostatic fibre, polybenzimidazoles, permanent heat resistant fire-proof fibrous material fire retardant protective clothing fabric.The present invention is using many
Component has the fire resistance fibre of ingrain fireproofing and polyamide fibre 66 blending with good heat resistance energy produces ring spinning line, fire-retardant
Effect is permanent, not combustion-supporting, do not melt and drip, and has high intensity, high temperature resistant, fire-retardant, superior thermal protective performance, hot for a long time simultaneously
The advantages of stability.
The anti-flaming viscose that the present invention adopts is by adding phosphorous, nitrogen ignition-proof element phosphoric acid class fire-retardant in stoste before spinning
Agent and be obtained, this fire resistance fibre run into heat burning when do not produce melt drip, not only there is anti-flaming function, and can provide superpower
Moisture management function, integrates protection with comfortable it is adaptable to industrial textile, protective garment, bunting etc..
The Flame Vinylon that the present invention adopts is to add flame retarded polymeric material and fire retardant, spinneret in poly-vinyl alcohol solution
After make.Additive have in stoste particle dispersion good the features such as, have preferable associativity with PVA simultaneously, can be successfully
By filter medium and spinneret orifice, obtained Flame Vinylon has high-strength, Gao Mo and fire resistance, applied range concurrently.
The synthetic fibre fiber of being lost that the present invention adopts is made up of aromatic main chain unit, and limited oxygen index is more than 38%, belongs to not
Combustion things matter.Synthetic fibre of being lost has the characteristic do not melted, and from fiery self-extinguishment, rate of being fuming is extremely low, nontoxic, not halogen-containing, belongs to environmental protection fine
Dimension.Synthetic fibre of being lost has high high thermal insulation, very high temperature resistant, thermally decomposes 600 DEG C of weightless temperature.
The polyamide fibre 66 that the present invention adopts, compared with polyamide fibre list 6 fiber, has good basic heat resistance, dimensional stability
And resistance to elevated temperatures, the ultimate strength conservation rate under heating status is higher.
But above-mentioned fiber has the following disadvantages：1. the difference in length of four kinds of fibers is larger, and carded sliver drawing-off effect is bad.2. hinder
Combustion viscose rayon is wet low by force, wears no resistance.Because there is above-mentioned deficiency, therefore multicomponent fire resistance fibre is carried out with polyamide fibre 66 blending
Spinning, with reinforcing fiber spinning property.
Content of the invention
For the deficiencies in the prior art, the technical problem to be solved be provide a kind of multicomponent fire resistance fibre with
Polyamide fibre 66 blending produces the methods and applications of ring spinning line, is that one kind has ingrain fireproofing by the yarn that the method obtains
