Description

A kind of flame retardant fabric
Technical field
The present invention relates to a kind of flame retardant fabric, belong to textile garment technical field.
Background technology
Needing possess special performance owing to job specification determines the garment material of a lot of industry, the such as all kinds of industries such as domestic and international petrochemical industry, natural gas, fire-fighting, army and police, aviation are required to the garment material possessing fire retardant performance.But the manufacturing technology that current inflaming retarding fabric uses all originates from Ao Wei company of Britain, the raw material that they use is THPC (THPC), but THPC has halogen, there is non-Environmental Factors, and flame retardant effect is not very stable, and fire resistance can reduce with increasing of washing times.In addition, " toxicity research of THPC-urea initial reduced body " that Wang Liyun etc. deliver shows, THPC decomposition can produce formaldehyde, there is harmful effect to human body.
In view of this, a kind of good flame retardation effect of invention, the flame retardant fabric of safety are needed.
Content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, a kind of good flame retardation effect, the flame retardant fabric of safety and environmental protection are provided.
For achieving the above object, the technical solution used in the present invention is:
A kind of flame retardant fabric, which is fibrous material, specifically includes woven, knitting or non-woven form fibrous material, and it uses following technique to prepare:
(1) padding fire retarding treating liquid: common cloth is padded fire retarding treating liquid, pick-up rate is more than 70% ~ 85%;Described fire retarding treating liquid comprises the low molecule preshrunk body of 400 ~ 600g/L tetrakis hydroxymetyl phosphonium sulfuric and acid amides, 4 ~ 6g/L surfactant and the highly concentrated polyethylene of 10 ~ 20g/L (Polyethylene);
(2) prebake: the prebake 10 ~ 20min in the drying baker of 80 ~ 90 DEG C of the cloth after step (1) is padded fire retarding treating liquid;
(3) ammonia cure: the cloth after step (2) prebake is carried out in ammon-smoking box ammonia cure process, and ammonia cure flow is 1200 ~ 1500L/min;
(4) aoxidize: the cloth after step (3) ammonia cure is padded oxidation solution that concentration is 30 ~ 35% again, and pick-up rate is 70% ~ 85%;The speed padding oxidation solution is 30 ~ 40m/min, places 2 ~ 2.5min, then clean in water after padding;
(5) dry: the cloth after washing step (4) dries 30 ~ 40s in the dryer of 100 ~ 110 DEG C.
Further, described acid amides is urea.
Further, described surfactant is AEO.
Further, in described step (4), washing temperature is 30 ~ 40 DEG C, and washing time is 5 ~ 6min.
Further, in described step (4), oxidation solution is hydrogen peroxide solution.
Further, the step of preshrunk is also included.
Further, content 68-72% based on the low molecule preshrunk body of described tetrakis hydroxymetyl phosphonium sulfuric and acid amides, iron content is less than 0.1%, and viscosity 50-70, available phosphorus is more than 10%, slightly yellow liquid.
Compared with prior art, the invention have the benefit that
Make the more environmentally-friendly more safety non-toxic of product tasteless after present invention employs THPS-U, instead of the halogen harm in THPC.After textile pad crosses fire retardant, the preshrunk body of THPS and acid amides formation penetrates in amorphous area and the gap of fiber.When ammonia cure, NH3 is crosslinked with the methylol in preshrunk body subsequently, through oxidation to stablize after fibrous inside forms fire-retardant condensate.Present invention employs the crosslinking method of uniqueness, according to the feature of ammonia, independent design ammon-smoking box, add ammonia cure tank, expand the capacity of ammon-smoking box, add before and after fabrics flame resistance stable in limit, add again production efficiency, on the basis of original, expand 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 is as increasing of washing times reduces, simultaneously this flame-proof treatment does not change the primary characteristic of fabric fibre, thus maintain original performance of fabric, there is chance fire carbonization, from fire self-extinguishment, the feature effectively preventing propagation of flame, the protective garment being made from can avoid flame to damage human body, provides effective security protection to human body.
Fire retarding treating liquid in the present invention includes 400 ~ 600 g/L THPS-U, 4 ~ 6g/L surfactant and the highly concentrated polyethylene of 10 ~ 20g/L, polyethylene is compatible in whole flame-retardant system, and the sliding degree between yarn can be increased, make cloth softness smooth, improve the tearing strength of fabric, thus the environment strength meeting clothes requires;Surfactant has very strong acid resistance, in the middle of assistance fire retardant uniformly penetrating to yarn, makes uniformly with the flame-retardant composition of a large amount on fabric, thus improves the performance of fire retarding treating liquid, and fire resistance is high.The present inventor, through substantial amounts of test and research repeatedly, has obtained optimal dressing liquid composition and ratio, has completed the present invention.
Flame retardant fabric provided by the present invention is soft, strength loss is little, substantially maintains comfortableness and the durability of fabric, is suitable for makeing all kinds of protective garment, bedding, adornment and the fire-retardant nightwear of children etc..
Detailed description of the invention
