Description
Technical field
The present invention relates to a kind of flame-retardant yarn comprising the aromatic polymer fiber containing sulfuryl and by its obtained fabric
And clothes, and their preparation method.Mainly application is prepared in permanent fire retardant to the yarn of the present invention, wear-resisting, comfort property is good
Protection camouflage fabric and clothes.
Background technology
Fire fighter, emergency response personnel, racing car personnel, army personnel, industrial production personnel are often exposed to flame
Or in high temperature, the protective garment or protective article that they need are in addition to needing with high temperature resistant and permanent fire retardant performance, also
Need that there is excellent anti-wear performance, simultaneously because the violent motion of human body and high temperature applicationss cause the amount of sweat of human body to arrange at double
Go out, also need to have good comfortableness, penetrability, gas permeability for the fabric of such a occasion and eliminate the work(such as peculiar smell
Energy.
What fabric or clothes currently used for such use used is mostly that cotton or cotton are fire-retardant with being done after other chemical fibre blending
The product of arrangement, there is cotton easily mould, intensity difference, the defects of flame retardant effect is not lasting, and heat resistanceheat resistant performance is bad.And washed using fire-retardant
The fibers such as synthetic fibre, nylon, because molten drop phenomenon is obvious, to produce secondary injury.What is used at present has high-temperature fibre (such as aromatics
Polyamide-based fiber, polyimide fiber and its modified fibre, polyazole fiber, carbon fiber preoxided thread etc.), can solve permanent
The problem of fire-retardant and thermal protection, but deposited in terms of printing and dyeing property (such as dyeing dye uptake, dyeing color fastness and bright degree)
Being contaminated on more difficult, dark color can not be contaminated, color fastness is low, and dye uptake is low, poor reproducibility, cost height (more than 250 DEG C of glass transition temperature,

Below dtex, the intensity of the high-strength high temperature-resistant inherent fire-retardant fiber (A2) is more than 10cN/dtex.
In the yarn, low-intensity high temperature resistant inherent fire-retardant fiber (A1) can assign yarn excellent fire resistance；
High-strength high temperature-resistant inherent fire-retardant fiber (A2) while yarn excellent fire resistance is assigned, due to its have it is higher strong
Spend modulus and preferable high temperature dimensional stability, it is thus possible to be that yarn also has preferable high temperature dimensional stability；Conventional resistance
Combustion fiber (B) can also reduce the production cost of yarn while yarn fire resistance is assigned；Fire-retardant fibre is added in the yarn
Cellulose fiber can improve the snugness of fit of yarn.
The content of each component in yarn, it is preferred that, contain high temperature resistant inherent fire-retardant fiber in the yarn by weight
(A) 25wt%-45wt%, conventional flame retardant fiber (B) 20wt%-40wt%, flame retardant cellulose fiber (C) 15wt%-35wt%.
It is furthermore preferred that, it is high containing low-intensity high temperature resistant inherent fire-retardant fiber (A1) 20wt%-40wt%. in the yarn by weight
Intensity high temperature resistant inherent fire-retardant fiber (A2) 5wt%-25wt%, conventional flame retardant fiber (B) 20wt%-40wt%, fire resistance fibre
Cellulose fiber (C) 25wt%-40wt%.
Wherein, the content of low-intensity high temperature resistant inherent fire-retardant fiber (A1) in the yarn is preferably in more than 20wt%,
Below 30wt%., can be to yarn if being more than 30wt% if the content being less than 20wt%, does not reach effective fire resistance
There is negative effect in printing and dyeing property and comfortableness.
The content of high-strength high temperature-resistant inherent fire-retardant fiber (A2) in the yarn is preferably 5wt%-15wt%, due to high-strength
Degree high temperature resistant inherent fire-retardant fiber (A2) has high-modulus, high shear resistance and low thermal contraction performance, and it burns in naked light
Room, only it is carbonized and does not shrink substantially, when its content in the yarn is more than 5wt%, yarn can keeps whole when naked light burns
The dimensional stability of dignity material, forms good into carbon backbone structure, then has positive influence to the index of thermal protection.But
More than 15wt%, if the fabric being consequently formed becomes easily to send out the content of high-strength high temperature-resistant inherent fire-retardant fiber (A2) in the yarn
It is crisp, it is not flexible enough, tear properties are influenceed, while itself carries color, has necessarily to the alternative of yarn or plant printing and dyeing
Limitation.
The content of conventional flame retardant fiber (B) in the yarn is preferably 20wt%-40wt%.The conventional flame retardant fiber (B)
When content in the yarn is higher than 20wt%, the anti-wear performance of fabric can be significantly improved, the pliability of fabric also improves therewith,
There are positive influences to comfortable and mechanical property the durability of fabric, and be conventional chemical fibre due to playing basis, printing and dyeing
Also relative maturity facilitates aspect.But if above-mentioned content is more than 40wt%, the melting of this conventional flame retardant fiber at high temperature
Phenomenon can adversely affect to the fire resistance of yarn, and the prevention for fire-spreading property is unfavorable.

The content of electric fiber in the yarn is 0.5-5%, preferably 1-4%, more preferably 2-3%.
In one embodiment, the fibre blend can be formed by the way that the intimate blend of fiber is made.If
Need, other chopped fibers can be made to be combined with the relatively uniform short fibre mixture.The blending can be by known in the art
Many methods are placed on creel to realize, including by many continuous filament yarn spools, while cutting two or more species
The long filament of type with formed cutting chopped fiber blend method；Or be related to shredding difference chopped fiber bundle, then opener, altogether
Shredding and the method that various fibers are blended in mixed machine and carding machine；Or various staple fibres are formed, then it is processed further
Form the method that mixture forms fibre blend bar such as in carding machine.Can use prepare fibre compact concurrent mixture its
His method, as long as various types of different fibers can be relatively evenly distributed in whole blend.If by the blend
Yarn is formed, then the yarn equally has the mixture of relatively uniform chopped fiber.In general, in most preferred embodiment party
In case, single chopped fiber shredding or separation can be extremely made to the normal degree of available fabric in fiber process so that due to
Fiber knot or fiber section caused by the bad shredding of chopped fiber and other major defects are not to impair the amount of final fabric quality
In the presence of.
In a preferred method, intimate blend of staple fibers is made as follows：First by the chopped fiber tied derived from shredding with appointing
What his chopped fiber (if needed for additional function) mixes.Then fiber blends are combed into using carding machine
Bar.In fiber industry, fiber is separated usually using carding machine, adjusts fiber, and fiber is delivered to Loosely coupled fibre
In the continuous strand of dimension, and without notable winding, it is commonly known as the carded sliver.Generally through but not limited to two-step stretch method by the carded sliver
It is processed into ripe bar.
The fibre blend is made to the mode of yarn can use this area conventional technology.Such as use ability
Spun yarn line is made in chopped fiber RING SPINNING technique known to domain, and usual staple length takes cotton system in 38-51mm；
65mm-102mm takes woolen system spinning.Processing process is：Fiber packet capturing → hopper mixing → opener → hopper →
Feed cotton machine → carding machine → drafting → rove → spun yarn → winder → mixed yarn.Road weaving process after yarn is sent into.
