Abstract
The invention relates to a flame-retardant fabric, which is made of fiber materials, and specially comprises fiber materials in a weaving, knitting or non-woven form. The flame-retardant fabric is prepared by using a flame-retardant process, and the main ingredients of the flame-retardant fabric include a low molecular pre-shrinking body of tetrakis hydroxymethyl phosphonium sulfate (THPS) and amide, a surfactant, a flame-retardant finishing liquid of high-concentration polyethylene, so that the flame-retardant fabric has a durable flame retardant performance, and the flame retardant performance is not reduced with the increasing of the number of washing times; the flame-retardant finishing does not change the original features of the fabric fibers, so that the fabric is soft in handfeel, and small in strength loss, and the comfortableness and durability of the fabric are basically kept, therefore, the flame-retardant fabric has a characteristic that the fabric is carbonized after meeting fire and self-extinguished after leaving fire, and the spread of flames is effectively prevented; and the protective clothing prepared by using the fabric can prevent flames from causing harm to the human body.
Description
Technical field
The present invention relates to a kind of fire-retardant cloth, belong to textile garment technical field.
Background technology
The garment material that has determined a lot of industries due to job specification need to possess special performance, and all kinds of industries such as domestic and international petrochemical industry, natural gas, fire-fighting, army and police, aviation all need to possess the garment material of fire retardant performance.But the manufacturing technology that current inflaming retarding fabric adopts is all to originate from Britain Ao Wei company, the raw material that they adopt is Tetrakis hydroxymethyl phosphonium chloride (THPC), but in THPC, there is halogen, there is non-Environmental Factors, and flame retardant effect is not very stable, and fire resistance can reduce along with increasing of washing times.In addition, the toxicity research > > of < < Tetrakis hydroxymethyl phosphonium chloride-urea initial reduced body that Wang Liyun etc. deliver shows, THPC decomposes can produce formaldehyde, and human body is existed to harmful effect.
In view of this, need to invent a kind of good flame retardation effect, the fire-retardant cloth of safety.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of good flame retardation effect is provided, the fire-retardant cloth of safety and environmental protection.
For achieving the above object, the technical solution used in the present invention is:
A fire-retardant cloth, it is fibrous material, specifically comprises fibrous material woven, knitting or non-woven form, it adopts following technique preparation:
(1) pad fire retarding treating liquid: common cloth is dipped to fire retarding treating liquid, and pick-up rate is greater than 70% ~ 85%; The high dense polyethylene (Polyethylene) of the low molecule preshrunk body that described fire retarding treating liquid comprises 400 ~ 600g/L tetrakis hydroxymetyl phosphonium sulfuric and acid amides, 4 ~ 6g/L surfactant and 10 ~ 20g/L;
(2) prebake: step (1) is padded to the cloth prebake 10 ~ 20min in the drying baker of 80 ~ 90 ℃ after fire retarding treating liquid;
(3) ammonia cure: the cloth after step (2) prebake is carried out to ammonia cure processing in ammon-smoking box, and ammonia cure flow is 1200 ~ 1500L/min;
(4) oxidation: be 30 ~ 35% oxidation solution by the cloth after step (3) ammonia cure dipping concentration, pick-up rate is 70% ~ 85%; The speed that dips oxidation solution is 30 ~ 40m/min, dips rear placement 2 ~ 2.5min, then in water, cleans;
(5) dry: the cloth after step (4) washing is dried to 30 ~ 40s in the dryer of 100 ~ 110 ℃.
Further, described acid amides is urea.
Further, described surfactant is fatty alcohol-polyoxyethylene ether.
Further, in described step (4), washing temperature is 30 ~ 40 ℃, and washing time is 5 ~ 6min.
Further, in described step (4), oxidation solution is hydrogen peroxide solution.
Further, the step that also comprises preshrunk.
Further, the low molecule preshrunk body of described tetrakis hydroxymetyl phosphonium sulfuric and acid amides is main content 68-72%, and iron content is less than 0.1%, viscosity 50-70, and available phosphorus is greater than 10%, micro-yellow liquid.
Compared with prior art, beneficial effect of the present invention is:
The present invention adopted make after THPS-U product more environmental protection safety non-toxic is tasteless more, replaced the halogen harm in THPC.Textile pad is crossed after fire retardant, and the preshrunk body that THPS and acid amides form penetrates in the amorphous area and gap of fiber.When ammonia cure, the methylol in NH3 and preshrunk body is crosslinked subsequently, at fibrous inside, forms fire-retardant condensate by being oxidized to stablize.The present invention has adopted unique crosslinking method, according to the feature of ammonia, independent design ammon-smoking box, increased ammonia cure tank, expanded the capacity of ammon-smoking box, increased in the front and rear side of fabrics flame resistance stable, increase again production efficiency, on original basis, expanded the multiple of ammonia cure.It is crosslinked that such flame-proof treatment forms durability, make it have the fire resistance of durability, and fire resistance does not reduce along with increasing of washing times, this flame-proof treatment simultaneously does not change the primary characteristic of fabric fibre, thereby the original performance that has kept fabric, have the fiery carbonization of chance, from fire, certainly put out, effectively prevent the feature of propagation of flame, the protective clothing of being made by it can avoid flame to damage human body, to human body, provides effective security protection.
Fire retarding treating liquid in the present invention comprises the high dense polyethylene of 400 ~ 600/L THPS-U, 4 ~ 6g/L surfactant and 10 ~ 20g/L, polyethylene is compatible in whole flame-retardant system, and can increase the slippage degree between yarn, make cloth softness smooth, improve the tearing strength of fabric, thereby meet the powerful requirement of environment of clothes; Surfactant has very strong acid resistance, assists fire retardant uniformly penetrating in the middle of yarn, makes the uniform flame-retardant composition with a large amount on fabric, thereby has improved the performance of fire retarding treating liquid, and fire resistance is high.The inventor, through a large amount of tests and research repeatedly, has obtained best dressing liquid composition and ratio, has completed the present invention.
Fire-retardant cloth provided by the present invention is soft, strength loss is little, has substantially kept comfortableness and the durability of fabric, is suitable for makeing all kinds of protective clothings, bedding, adornment and the fire-retardant nightwear of children etc.
