The embodiment of the present invention 1~14 carries out testing vertical flammability with comparative example 1~11 according to GB/T 5455-2014, surveys
Determine afterflame and smoldering time.
Table 1 is the after flame time and smoldering time obtained by test.
The after flame time of table 1 and smoldering time
By above experimental result, it can be deduced that to draw a conclusion:
(1) all embodiments can control afterflame within 2 seconds;
(2) no matter embodiment or comparative example, will can not glow control be 0 second;
(3) modacrylic and the flame-retardant textile of Lyocell fibers blending glow it is obvious that up to more than 5 seconds.It is poly- to add 10%
Acid imide, no significant change of glowing, more than 5 seconds.As shown in table 2.
Table 2
(4) ensure fabric not by burn through, occur without melting or molten drop in the case of, in modacrylic and Lyocell fibers
The middle nylon for adding proper proportion, obvious shortening of glowing, can be controlled within 5 seconds or 2 seconds.As shown in table 3.
Table 3
(4) ratio of modacrylic is higher, and smoldering time has elongated trend.As shown in table 4.
Table 4
(5) Gram Mass of fabric is bigger, and smoldering time has relatively longer trend.As shown in table 5.
Table 5
(6) when the Gram Mass of fabric is less than 185, there is burn through in combustion test in fabric, is determined as not fire-retardant.Such as
Shown in table 6.
Table 6
(7) when the Gram Mass of fabric is higher than 338, fabric glowing more than 5 seconds in combustion test.As shown in table 7.
Table 7
(8) in the case where polyimide fiber be present on a small quantity, nylon is added in modacrylic and Lyocell fibers, it is right
Control is glowed still favourable.As shown in table 8.
Table 8
(9) for nylon content more than 15%, fabric occurs melting in combustion test or molten drop, is judged as not fire-retardant.Such as
Shown in table 9.
Table 9
(10) smoldering time of the mixing of modacrylic and the mixing ratio modacrylic and Lyocell fibers of cotton is relatively long, such as
Shown in table 10, and after 10% nylon of addition, within still uncontrollable to 5 seconds.In the present invention, modacrylic, lyocell are fine
When peacekeeping nylon three is with mixing, and meeting Ben Fanming allowed band, control can will be just glowed within 5 seconds or 2 seconds.Such as
Shown in table 11.
Table 10
Table 11
If using conventional design, add the phosphorous flame-retardant viscose glue 15% of Lenzin company, reduce Lenzin tencel or in it is difficult to understand
Bamboo 15% is glowed to control, and cost of material relative will rise.Table 12 is regular price on the market.

Calculated according to conventional fibre to fabric loss 20%, glowed using anti-flaming viscose control, increase the feelings of cost
Condition such as table 13.
Table 13
Note:Cost of material increases cost=[the phosphorous system's anti-flaming viscose of ∑ (fiber unit price X proportion of fibers) not phosphorous system of-∑
Anti-flaming viscose (fiber unit price X proportion of fibers)] X fabrics Gram Mass/1000;Raw material increase cost=raw material increase cost/
Use cost of material X100% before anti-flaming viscose.
As can be seen from the above table using routine phosphorate be viscose glue scheme, cost of material can rise 15.65%~
31.25%, use the advantage of lower cost of technical solution of the present invention.
If without using phosphorate be anti-flaming viscose scheme, and by it is additional post-process fire-retardant mode and reduce glow, it is former
Material cost will not be improved, but processing cost can be improved accordingly, while when post-processing fire-retardant, the color of fabric has certain change,
Physical property table can also decline to a certain degree, can also bring the healths such as formaldehyde, environmental protection aspect the problem of.Conventional post processing resistance
It is 6 yuan/every meter to fire processing charges, even if being calculated by oneself yuan/meter of processing cost 4, processing cost can increase substantially, concrete numerical value
Such as table 14.
Table 14
Note:Increase processing cost=processing cost increases/post-processes cost of material X100% before fire-retardant processing.
Relative to the cost of material before the fire-retardant processing of post processing, processing cost adds 21.23%~31.58%.Equally
It can prove that the solution of the present invention has preferable economy.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
Enclose and be defined, on the premise of design spirit of the present invention is not departed from, technical side of the those of ordinary skill in the art to the present invention
The various modifications and improvement that case is made, it all should fall into the protection domain of claims of the present invention determination.
