Description
Technical field

The method and products thereof that fire resistance fibre is prepared after oxidation.
Background technique
Fire-retardant problem is always the lasting problem that chemical fiber plus material is faced, and has had some solution party's cases at present
It is such as solved from the origin of fiber, aramid fiber, polyimide fiber can be prepared, prepare fire-retardant fibre for example, by using fire retardant addition
Dimension, can satisfy the flame-retardancy requirements of fabric substantially, has a wide range of applications at present in some security fields, but this fiber
There is irremediable defect: first, as the fiber costs such as aramid fiber and polyimides are too high, existing market lowest price is in 100,000/ton
Left and right, this price are difficult to receive for traditional textile；Second, fibrous mechanical property is poor, and it is more next to be knitted fabric at present
It is more, especially warp-knitted face fabric using more and more extensive, but, aramid fiber and polyimides also higher to the mechanical performance of fiber
Fiber is since its molecule chain rigidity is too strong, and the fabric of braiding has certain prodding and itching feeling, and comfort level is inadequate, and adds fire retardant
Fiber is limited its scope of application due to the mechanical performance for affecting fiber of its fire retardant；Third, heat resistance is poor,
Polyimides and aramid fiber heat resistance are good, but the characteristic of its material itself limits it in the application of clothes and home textile,
The fiber heat resistance for adding fire retardant will be lower than general fibre, this also affects its use scope；4th, industry is applied to
This height, since the heat resistance of fiber declines, substantially industry aramid fiber and is gathered with receiving considerable restraint for the mode of fire retardant addition
Acid imide holds at high price, and application cost is higher.
The technology of preparing of fire resistance fibre also rests in the developed countries such as America and Japan hand at present, the exploitation for Chinese products
It is unfavorable.More fabric is the flame retarding function that fabric is realized using fire retardant final finishing, this mode currently on the market
Cost is relatively low relative to using for conductive fiber, significant effect, therefore is also used by most of fabric producers, but this
Mode although it is cheap effectively, but there is also inevitable defects: 1) adding pollution, be usually used at present whole after fire retardant
Reason, increases the pollution level of waste water, also increases the processing difficulty of waste water；2) persistence is inadequate, it is currently used it is fire-retardant after
Collator Mode washability is bad, and general few washabilityes that can reach standard requirements are unfavorable for the outlet of textile, reduce
The competitive advantage of textile increases the dispute in trade.

Fiber during spinning between cortex and sandwich layer different component group there are interfacial effect, with the presence of certain not moving air,
Heat transfer is completely cut off in short time, so that core fibers are not oxidized, so that composite construction fire resistance fibre of the present invention is soft
Soft, high temperature resistant, mechanical property are good.
It is most two ways of the fire-retardant use of current textile fabric using fire resistance fibre and flame-retardant after-finishing, and this skill
Art invention proposes the third mode: new fire resistance fibre is prepared using skin-core structure bicomponent fibers, fibre diameter can be done
To superfine fibre, fiber can be made light color, permanent flame retarding function, and mechanical performance can achieve the standard of general fibre, complete
The full up various woven requirements of foot, cost is suitable with flame-retardant after-finishing, low in cost, reduces pollution, promotes the attached of textile
It is value added.
Composite fibre of the present invention have the function of it is fire-retardant, and due to realize composite fibre cortex flame-retardant layer uniformly point
Cloth, therefore the mechanical property for assigning flame-retardant fiber function, and maintaining polyester fiber itself, have good knitting property.
