Description
Technical field
The present invention relates to yarn, fabric, garment industries, more particularly to a kind of flame-retardant yarn, fabric, clothes.
Background technique
The industry such as metallurgy, steel industry, shipbuilding, the clothes of the operating personnels such as electric welding, Metal Cutting, casting, which protect, is always
One intractable technical problem.Traditional method is the canvas for using more than 400 grams every square metre, and a small amount of melting residue splashes down
After clothes, is gone back by the concave-convex crosspoint diffusing reflection of canvas plain weave, there is certain protection effect.But if it is blast-furnace man or
For the post of founder or the operation of Long Term Contact molten metal, not fire-retardant canvas not only without protective capacities, once by
It ignites, cotton will become good fuel, release a large amount of heat, cause to wear personnel's large-area burns.Later people are by sail
Cloth carries out fire-retardant post-processing, fire-retardant as solving the problems, such as, but after effect of splashing once being formed, the flowing of molten metal liquid
Property, which reduces rapidly, pays in clothing surface, sustained release heat, quickly burns clothes, people is scalded, cotton post-processes fire-retardant
The protective action that canvas clothes play is very limited.Use the solution party of the skin damage of the heavily fabric of ox-hide or wool substitution people
Case is come into being, and also occurs wool and the viscose blended heavy fabric of phosphorous flame-retardant on the market, and protection effect further obtains
It improves, due to having used the preferable ox-hide of heat insulation effect, wool, cotton and phosphorous flame-retardant viscose glue, cloth is again very thick and heavy, often often
Gram Mass reaches 350g or more, and the worker's of dress works in molten metal attachment, and comfortable sexual abnormality is poor, wool and phosphorus system
The blended clothes of anti-flaming viscose are easy Peng Run after washing and shrink, and often wash primary contraction once, the wearability of clothes is very poor.
So far there are no one kind can trust that the fiber taken or fabric can maintain it substantially special at a high temperature of 600 degrees Celsius
Property.The natural scale structure of wool is in anti-metal melting splash, so far still without alternative solution.How to be mixed with other fibers
It closes, improves the effectiveness of wool scale, reduce its loss, and improve whole anti-flammability, improve washing shrinking percentage, and can suitably control
This is made, becomes a technical problem.

Test, -10%≤washing shrinking percentage≤+ 10%.
The embodiment of the present invention and comparative example are all made of 64# australian wool, pass through subtle shrink-resistant finish appropriate, decrement control
System is within 1%.
Common wool can generally carry out the mature technologies such as Basolan processing, resin shrink-resistant finish, mercerising processing, soften,
Passivation or part removal wool scale, change scale outside degree of opening, reduce wool forward with reversed coefficient of friction
Difference, to reduce the wash shrinkage rate of wool fabric.The present invention needs to retain as far as possible the degree of opening of wool scale, microcosmic upper shape
Greatly it is not easy the outer surface of infiltration at surface tension, is with the wash shrinkage rate for reducing fabric by wool processing technology
Implacable contradiction.Wherein, the scale of wool is as shown in Figure 1.
Now anti-flaming viscose at present on the market is broadly divided into three categories.One kind is that organophosphorous fire retardant and viscose glue high score is added
Son forms the structure of hinge, and viscose glue molecule burns under the action of fire source, and organophosphorous fire retardant also burns immediately, but organic phosphorus combustion
The reticular structure of 5 valence phosphorus is formed after burning, and oxygen is prevented to react with the further of viscose glue molecule, it is automatic under the action of losing fire source
Extinguish.Another kind of is that inorganic silica (SiO is added in viscose glue molecule2) superfines, silica is non-combustible matter,
The burning for hindering viscose glue, reaches certain anti-flammability.But inorganic SiO 2 powder is very hard, is easy to dissolve out after washing, people
Skin contact can itch after, use scope is limited, is not suitable for apparel applications.There are also the silicon nitrogen that a kind of exactly present invention uses
It is fire-retardant that organic silicon nitrogen system is exactly added in the characteristics of being anti-flaming viscose, combining preceding two classes anti-flaming viscose between viscose glue molecule
Agent is built bridge by polyvalent metal, and fire retardant is allowed not dissolve out easily, under fire source effect, viscose glue burning, and the organic resistance of silicon nitrogen system
Combustion agent is also burnt immediately, ultimately forms the silicon nitrogen reticular structure based on silica composition, prevents oxygen and viscose glue molecule
Further reaction, the automatic distinguishing under the continuous action for losing fire source.The anti-flammability of the fiber is very high, and limit oxygen index is reachable
33% or more, 80% or more quality can be maintained at a high temperature of 800 degrees Celsius, and other two kinds of flame retardant viscose fiber are in identical item
60% or more is oxidized decomposition under part, and quality maintains percentage to be no more than 40%.What the embodiment of the present invention and comparative example used
Specification is 2.2dtX88mm.
Conventional nylon fiber is nylon 6 or nylon66 fiber, specification 1.67dtX76mm on the market.
Fusion proof metal splash experimental method reference standard EN ISO 9185-2008 of the present invention.Such as Fig. 2 institute
Show.Standard specification PVC film, if any the cavity 5mm or more, is judged to protecting and fails after casting metal melt liquid 30 seconds.Not lose
Premised on losing, the quality (g) of the most metal melting liquid being poured determines the protective capacities of tested fabric.
The judgement benchmark of EN ISO 11612-2015 is shown in Table 1.
Table 1
The indexs such as fusing point, boiling point, the specific heat capacity of each metal (99.9% or more purity) are shown in Table 2.
Table 2
Fusing point of the iron (steel) in conventional heavy metal be it is highest, reach 1538 degrees Celsius, due to the pass of molten iron purity
System, come out of the stove or splash come out molten iron temperature substantially in 1400 degrees centigrades.Because of the presence of a small amount of impurity, molten iron is 1400
Degree Celsius when ot-yet-hardened.Molten iron can represent remelting substantially and melt metal liquid, and the fabric of the anti-molten iron of energy can substantially prevent other
The equivalent splash of metal liquid is melted in remelting.Since the molecule two of heavy metal is big, specific heat capacity is low, and the surface tension of melt liquid is big,
The heat for solidifying release is relatively small, and the superficial layer of melt liquid, which is easy to produce, after contact room temperature object bursts phenomenon, forms four
Scattered spark, in test molten metal rolls the fast speed to glide.Temperature tolerance requirement due to absolute temperature height, to fabric
It is higher.
The fusing point of aluminium is 660 degrees Celsius, due to the aluminum electrolysis technology being widely used, is in a cell made molten cryolitic
For solvent, it is more than 2000 degrees Celsius of alumina dissolution by fusing point, the cathode of electrolytic cell is acted on by the heavy current of direct current
Metallic aluminium is obtained, the temperature of electrolytic cell is controlled substantially at 950~970 degrees Celsius in production process, and aluminum water tapping temperature is substantially
780 degrees centigrades.The melt liquid of aluminium is the Typical Representative in non-heavy metal classification, and the fabric of the anti-aluminum water splash of energy can also be prevented
The equivalent splash of metal liquid is melted in other such as non-remeltings of magnesium, zinc, tin.The molecular weight of molten aluminum is lower than molten iron, and specific heat capacity is probably
1.5 times of iron, solidification heat release (heat of fusion) is 10 times of molten iron or more, and aluminum water is about 120 degrees Celsius beyond solidified aluminum temperature, is melted
The surface tension for melting liquid is more much lower than molten iron, is liable to stick on contactant surface, melt liquid flows down from fabric surface
Speed it is relatively slow, if contact room temperature object, molten metal liquid can not be dropped into setting temperature hereinafter, molten liquid rapidly
The stickiness meeting substantial increase of body, flow rate of liquid further decrease, and are easy the attachment to extend into musculus cutaneus shape under the effect of gravity,
Caused by heat injury it is more serious than molten iron.
To sum up analyze, it is considered herein that anti-aluminum water splash is consistent with the principle of anti-molten iron splash, the low aluminum water of absolute temperature
It is more difficult to take precautions against, preferentially ensures the protective performance of aluminum water splash.Thinking of the invention is, it is ensured that the case where fabric instantaneous anti-flammability
Under, it allows molten metal liquid to slide as early as possible as far as possible, does not generate attachment, to achieve the purpose that not scald the personnel of dress.To wool
Anti-shrinking it is very slight, keep the open state of wool scale as far as possible, allow wool and molten metal liquid is more point contact
Rather than face contact, a possibility that reducing heat transference efficiency, to greatest extent fragmentation molten metal liquid, reduce attachment.Utilize silicon
Nitrogen system viscose glue carbonization speed is fast, low advantage of absorbing heat, it is ensured that the temperature of molten metal liquid not rapid decrease is formed after carbonization
SiO2Occur certain exothermic reaction (* note) with the aluminum water of contact fabric, substantially the heat absorption of counteracting fabric carbonization, contact is allowed to knit
The aluminum water skin temperature of object does not decline substantially, and viscosity does not greatly improve, it is ensured that the gliding speed of aluminum water.Wool scale is every time and aluminium
Scale passivation abrasion will occur for the contact of water and carbonization, the limit oxygen index of wool only have 24~26%, and anti-flammability is less high,
The relative scale of anti-flammability higher silicon nitrogen system's viscose glue and wool cannot be below some limiting value.Otherwise silicon nitrogen system's viscose glue and wool
Relative scale can not be excessively high, otherwise the wool scale in basis is less, and the ability of fragmentation aluminum water dies down, SiO2
Excessively fierce with the exothermic reaction of aluminum water, wool scale is finally lighted or is scalded and wear fabric, safeguard function disappears by flash carbonization.
Since the scaling processing of wool is very slight, contraction meeting after fabric washing it is obvious that and it is irreversible, the maintenance in use is very numb
It is tired.A small amount of nylon is added in the present invention, tentering, holding fabric do not have certain elasticity as far as possible in textile finishing processes, and reduction is washed
Wash shrinking percentage.The amount of nylon is more, and to reducing, wash shrinkage rate is more advantageous.But nylon does not have anti-flammability, and temperature tolerance is also very poor, makes
Dosage is no more than some range.

Reaction is violent aluminothermic reduction process.Al2O3Fusing point be 2057 degrees Celsius, it is Celsius far beyond aluminum water 780
Degree, Al2O3It after surface layer is precipitated on a small quantity, solidifies immediately, surface tension increases suddenly, in the case that fabric itself melting does not occur, and knits
The adhesive force of object disappears substantially.
The present invention through a large number of experiments, has summed up the proportional region of each fiber proposed in technical solution.
The present invention compared with the existing technology, protrudes effect and is:
The present invention manufactures after spinning by the way that by wool, silicon nitrogen system's anti-flaming viscose and nylon, range is mixed according to a certain percentage
At fabric, then it is sewn into clothes.Make full use of the elasticity of wool scale by molten metal liquid fragmentation, silicon nitrogen system anti-flaming viscose is fast
Residual weight is big after speed carbonization and carbonization, absorbs the small advantage of heat, allows molten metal liquid quickly to slide, cloth is breakdown
Possibility reduces, so that the degree that the personnel of dress are burned reduces.But also using the thermoelasticity of nylon, the elasticity of fabric is allowed
Increase, is formed by the arrangement stage, the shrinking percentage of clothes service stage is controlled lower, thus guarantee the clothes of the fabric
Wearability.
Illustrate with reference to the accompanying drawing and specific embodiment to the flame-retardant yarn of fusion proof metal splash of the present invention, knit
