Abstract
The invention discloses a method for prolonging acid-base penetrating time of an aramid fabric. The method comprises the following specific steps: preparing acid-base preventing working liquor at first; and then padding the aramid fabric in the prepared acid-base preventing working liquid, stentering and drying at the temperature of 100-120 DEG C, baking for 1 minute at the temperature of 170-180 DEG C, preshrinking, checking and packing. Requirements of the primary standard of the acid-base penetrating time are met basically, an implementing process is convenient and simple, special equipment is not required, the aramid fabric can be produced in common printworks, so that aramid fibers which are high-performance fiber fabrics can be used well, and particularly, workers can be protected well in flammable and combustible places and places which are in contact with chemical substances for a long time.
Description
Technical field
The invention belongs to the technical field of improvement of aramid fabric is and in particular to when a kind of lifting anti-soda acid of aramid fabric penetrates
Between method.
Background technology
Aramid fiber has high-tenacity, high abrasion, acid-alkali-corrosive-resisting and the performance characteristics such as fire-retardant because of it, is modern high performance
The Typical Representative of fiber, the fabric made with aramid fiber, natural have fire-retardant and acid-alkali-corrosive-resisting performance, using aramid fiber
Anti-flammability, corrosion resistance refuse acid treatment along with surface, and the clothing that can make vapor-permeable type fire prevention, anti-soda acid splash are it is desirable to take
Dress not only will be prevented fires, acid-alkali-corrosive-resisting, also requires non-sticky to the soda acid liquid in the splash of surface dirty, impermeable, so some row
Industry standard specifies that this requirement is：（1）, refuse soda acid efficiency（Before washing and after washing）More than 90%；（2）, soda acid time of break-through
Wash first more than 30 minutes, require after washing to reach more than 3 minutes.But, the characteristic by aramid fiber itself is determined, surface
Refuse acid-alkali treatment fortunately to reach, and the time of break-through of surface acid ＆ alkali liquid body is difficult to meet require substantially, after especially washing just
More difficult, good fabric lining originally, also very acid and alkali-resistance penetrates, and but because this index can not be up to standard, does not just have
Protect the effect of labourer well, need to improve.
Content of the invention
Present invention solves the technical problem that there is provided a kind of method of lifting aramid fabric anti-soda acid time of break-through, the party
Find during method Binding experiment that C8 waterproofing agent has higher initial soda acid time of break-through but non-wash resistant, and C6 waterproofing agent tool
There is higher washable soda acid time of break-through but initially poor, the waterproofing agent of two kinds of models is pressed 1 by the present invention:2 weight proportion mixes
Close application, and effectively improve aramid fabric anti-soda acid time of break-through with the use of special-purpose water-proof penetrating agent and bridging agent.
The present invention is to solve above-mentioned technical problem to adopt the following technical scheme that, when a kind of lifting anti-soda acid of aramid fabric penetrates
Between method it is characterised in that concretely comprising the following steps：
It is first according to following mass concentration and prepare anti-soda acid working solution,
C8 waterproofing agent 40-60g/L；
C6 waterproofing agent 80-120g/L, the mass concentration of this C6 waterproofing agent is 2 times of C8 waterproofing agent mass concentration；
Waterproof agent aliphatic ethanol 2.5-5g/L；
Bridging agent is etherified hexamethylol melamine resin 15-20g/L；
Then aramid fabric is padded the anti-soda acid working solution preparing, dry in 100-120 DEG C of tentering, roast then at 170-180 DEG C
Dry 1min, preshrunk, test package.
Further preferably, described aramid fabric adopts 93wt% aramid fiber 1313,5wt% Fanglun l414 and 2wt% conductive fiber
Weaving forms, and weight is 180g/m2.
The present invention has substantially met the requirement of anti-soda acid clothing time of break-through primary standard, and implementation process is convenient and simple, no
Need special equipment, can produce in general printworks, so that this high-performance fiber fabric of aramid fiber is preferably
Used, particularly in some inflammable and explosive and long-term places contacting with chemical substance, labourer can be played preferably
Protective effect.
Specific embodiment
Describe the particular content of the present invention in detail in conjunction with the embodiments.
Embodiment
Prepare anti-soda acid working solution：
1st, C8 waterproofing agent 40g/L, C6 waterproofing agent 80g/L, waterproof agent aliphatic ethanol 5g/L and bridging agent etherificate six
Melamine methylol resin 15g/L；
2nd, C8 waterproofing agent 60g/L, C6 waterproofing agent 120g/L, waterproof agent aliphatic ethanol 2.5g/L and bridging agent etherificate
Hexamethylol melamine resin 20g/L；
3rd, C8 waterproofing agent 50g/L, C6 waterproofing agent 100g/L, waterproof agent aliphatic ethanol 4g/L, bridging agent etherificate six
Melamine methylol resin 18g/L.
Processing technological flow：
Aramid fabric is formed using the weaving of 93wt% aramid fiber 1313,5wt% Fanglun l414 and 2wt% conductive fiber, and weight is 180g/
m2；Aramid fabric is padded the anti-soda acid working solution preparing, dry in 100-120 DEG C of tentering, bake then at 170-180 DEG C
1min, preshrunk, test package.
Index test：
The test of soda acid time of break-through is according to GB24540-2009-5.2.1.1（One-level）
| Project | Standard value | Actual measurement before washing | Survey after washing |
| 40% nitric acid t/min | Wash front t >=30, wash rear t >=3 | 36 | 10 |
| 80% sulphuric acid t/min | Wash front t >=30, wash rear t >=3 | 50 | 10 |
| 30% hydrochloric acid t/min | Wash front t >=30, wash rear t >=3 | 34 | 11 |
| 30% Caustic soda t/min | Wash front t >=30, wash rear t >=3 | 40 | 20 |
As can be seen from the table above, the requirement of anti-soda acid clothing time of break-through primary standard, implementation process side have been substantially met
Just simply it is not necessary to special equipment, can produce in general printworks, so that this high-performance fiber face of aramid fiber
Material is preferably used, and particularly in some inflammable and explosive and long-term places contacting with chemical substance, labourer can be risen
To more preferable protective effect.
The ultimate principle of the present invention, principal character and advantage have been shown and described above, without departing from the present invention spirit and
On the premise of scope, the present invention also has various changes and modifications, and these changes and improvements both fall within claimed invention
Scope.
