Description
Technical field
The present invention relates to flame-retardant textile technical field more particularly to a kind of regenerated celulose fibres.
Background technique
Fabric will realize flame retarding function, and generally there are two types of methods:
1, chemical processing will be carried out in non-flame resistant fabric or fiber；Chemical drugs artificially are carried out to non-flame resistant fabric or fiber
Agent dipping fire-cures or in non-flame resistant web surface or fiber surface coating flame retardant chemicals layer；To non-flame resistant fabric or fiber
It is obtained cheap with flame retarding function fabric for carrying out the benefit of fire-retardant post-processing, but the anti-flammability of fabric can be with washing
The increase of number and decline；In addition, the carcinogens such as the meeting such as remaining chemical agent sustained release formaldehyde on fabric, and producing
The pernicious gas of exhaust emission environment is understood in the process.
2, using the fire-retardant mode of material, i.e. the fiber of composition flame-retardant textile or fiber combinations itself have anti-flammability, are not required to
Want fire-retardant post-processing.The anti-flammability of material flame-retardant textile is stablized, but price is high；The exploitation and processing of material flame-retardant textile are relatively tired
It is difficult.Therefore market is good at low cost, comfort and the demand of the fire resistance fibre of handling ease is very big.
Fire-retardant regenerated cellulose fiber currently on the market is mainly being based on viscose glue, Modal, bamboo fibre or lyocell
On the basis of equal regenerated celulose fibres, addition organophosphorous fire retardant, quartz (silica) fire retardant, nitrogenated flame retardant,
Silicon nitrogenated flame retardant, bromide fire retardant and carbon flame retardant are made；The pole of regenerated celulose fibre is made by above-mentioned material
Limited oxygen index be greater than or equal to 28, above-mentioned regenerated celulose fibre is mixed with other fire resistance fibres, then by spinning with
Weaving, braiding or nonwoven processes obtain material flame-retardant textile；Material flame-retardant textile made from the above method is used for individual protection
Or household flame protection etc..Due to having the presence of regenerated celulose fibre, regenerated celulose fibre tool in material flame-retardant textile
Standby preferable water absorbing capacity, can increase the comfort of material flame-retardant textile；Therefore the material flame-retardant textile use scope is more next

The non-flame resistant fiber such as cotton, viscose glue, fiber crops and wool carries out the mixing close to 1:1, and to non-flame resistant fiber without any resistance
Combustion processing；Obtained mixture is integrally still able to maintain 28 or more limit oxygen index.
But the above-mentioned fire-retardant regenerated cellulose fiber referred to and synthetic fibers all have respective defect:
For above-mentioned fire-retardant regenerated cellulose fiber, fire-retardant regenerated cellulose fiber can only be mixed with fire resistance fibre
It closes；If fire-retardant regenerated cellulose fiber is mixed with non-flame resistant fiber, if the content of non-flame resistant fiber more than 10%, mixture
Entirety will lose anti-flammability.If fire-retardant regenerated cellulose fiber is mixed with other fire resistance fibres, the overall flame of mixture
Property will be lower than the anti-flammability of any single fire resistance fibre in mixture；That is the fiber can only be carried out with fire resistance fibre
Mixing, it is lower with the anti-flammability fitness of fire resistance fibre.
For above-mentioned synthetic fibers, synthetic fibers are mixed with non-flame resistant fiber, the dyeing property difference of two kinds of fibers
It is huge, and dyestuff is not also identical；Synthetic fibers must be using two bath methods when flame-retardant textile is made；Two bath process are complicated, and control
System is difficult；Efficient long vehicle dyeing assembly line cannot be used to be processed, should not be widely applied.
