Brief description of the drawings
Fig. 1 is flow chart of the present invention.
Embodiment
Below with reference to the accompanying drawings 1 and combine embodiment come the present invention will be described in detail, but not be to the present invention protect The process involved by the restrictions embodiment of scope is protected, is then conventional method or step unless otherwise instructed, medicine used Unless otherwise indicated, it is commercially available.
The present invention provides a kind of production technology of fire-retardant all-cotton knitting cloth, wherein, the production technology includes following step Suddenly：
（1）Pad fire retarding treating liquid：The all-cotton knitting cloth examined and spliced is padded into fire retarding treating liquid, an immersing and rolling, rolls Remaining rate 85 ~ 90%, wherein pick-up are also liquid carrying rate, are the liquid weight of band and the percentage of fabric weight itself, tool on fabric It is the solution weight of band and original fabric weight before padding on cloth cover after being rolled by roll after solution on stock tank band for body The percentage of amount；
（2）Low temperature preliminary drying technique：Eight sections for padding the all-cotton knitting cloth after fire retarding treating liquid and being sequentially transmitted forming machine are dried Case, and eight section baking oven setting preliminary drying temperature are 60 ~ 65 DEG C, cloth conveying speed is 10 ~ 20-m/min, to the all-cotton knitting Cloth carries out preliminary drying processing, all-cotton knitting cloth is contained damp rate control in the range of 12 ~ 14%, after padding fire retarding treating liquid All-cotton knitting cloth carries out low temperature preliminary drying processing, is conducive to fire retarding treating liquid and adheres to and shape on the all-cotton knitting cloth, And during low temperature preliminary drying, strict temperature control is at 60 ~ 65 DEG C, because at high temperature in acid fire retarding treating liquid to complete The damage of cotton knitting cloth is very big, and the damage to the all-cotton knitting cloth can be effectively reduced using 60 ~ 65 DEG C of low temperature Wound；
（3）Ammonia cure technique：Pre-baked all-cotton knitting cloth is subjected to ammonia cure processing in ammoniater, ammonia cure flow is 25 ~ 35m3/ H, speed are 9 ~ 17m/min, and during ammonia cure, the fiber on fire retardant and all-cotton knitting cloth is crosslinked one by NH3 molecules Rise, be conducive to fire retardant and be attached on the all-cotton knitting cloth, there is cloth fire-retardant；
（4）Oxidation neutralizes washing process：By the all-cotton knitting cloth conveying after ammonia cure into overflow machine, water for 3500 ~ 4500kg, carry cloth wheel speed as 25 ~ 35min of hydrogen peroxide washing under 180 ~ 220r/min, carries out alkali cleaning 25 ~ 35 twice afterwards（30） Min, at 75 ~ 85 DEG C wash 55 ~ 65min, then at 55 ~ 65 DEG C wash 40 ~ 50min, afterwards at 35 ~ 45 DEG C washing 25 ~ 35min, last 25 ~ 35min of cold water flush, in water-washing process is aoxidized, hydrogen peroxide can be by fire retardant（Tetramethylol chloride and The condensate of urea）In P3+It is oxidized to P5+, so that cloth reaches wash fast effect；
（5）Shaping and drying technique：The water washed all-cotton knitting cloth is entered into automatic dehydration open-width after disk roller roll-in Open-width is carried out in machine, then the all-cotton knitting cloth is delivered to and is arranged in sequence with the forming machine of 6 ~ 8 section baking ovens, the cotton The speed of knitting cloth transmission is 10 ~ 20m/min, carries out cold front heavy rain, run-bake-needle fault contraction after then being come out from forming machine successively, into Enter to examine unit check cloth quality, last clot cloth outputting, obtains all-cotton knitting cloth.
In the inventive solutions, it is in water into overflow machine by the all-cotton knitting cloth conveying after ammonia cure 3500 ~ 4500kg, carry cloth wheel speed and wash 25 ~ 35min for hydrogen peroxide under 180 ~ 220r/min, afterwards water for 3500 ~ 4500kg, carry cloth wheel speed and carry out 25 ~ 35min of alkali cleaning twice for 180 ~ 220r/min, and 55 ~ 65min is washed at 75 ~ 85 DEG C, 40 ~ 50min is washed at 55 ~ 65 DEG C again, washes 25 ~ 35min, last 25 ~ 35min of cold water flush at 35 ~ 45 DEG C afterwards, its Middle hydrogen peroxide concentration is 20 ~ 30g/L, and the concentration of lye is 0.8 ~ 1.4g/L, and the concentration of preferably described hydrogen peroxide is 26 ~ 28g/ L, the concentration of lye is 0.9 ~ 1.2g/L, and alkali cleaning is to neutralize the acid that fire retardant produces after peroxidating, and high temperature is washed, is low Warm water is washed, cold water wash be in order to wash away on the all-cotton knitting cloth remaining free formaldehyde, ammonia, hydrogen peroxide, alkali etc. other The impurity being deposited on.
In another embodiment of the present invention, the water washed all-cotton knitting cloth is passed through into the roller that pick-up is 60 ~ 75% Enter after wheel roll-in in automatic dehydration scutcher and carry out dehydration open-width, then the all-cotton knitting cloth is conveyed into forming machine, Using hot air circulation, jet does at drying the all-cotton knitting cloth to 6 ~ 8 section baking ovens being arranged in order in the forming machine up and down Reason, often save oven temperature be 120 ~ 150 DEG C, transmission speed be 10 ~ 20m/min, then from forming machine come out after the cotton Knitting cloth carries out cold front heavy rain successively, run-bake-needle fault is shunk, into unit check cloth quality is examined, and last clot cloth outputting, obtains All-cotton knitting cloth.The all-cotton knitting cloth of embodiment production using the present invention color change before and after flame-proof treatment is smaller, In 4 grades of gray scale, do not occur the even phenomenon of irregular colour on cloth, improve the Grade A delivery ratio of cloth, Grade A by 50 ~ 60% originally are improved to more than 90%, and different batches, with batch solid colour, favorable reproducibility, improves market and occupies Rate.
In the concrete scheme of the present invention, the fire retarding treating liquid includes：Fire retardant：350 ~ 400g/L, softening agent：20~ 30g/L, bleeding agent：1 ~ 2g/L, wherein the percentage by weight of the fire retarding treating liquid each component：Fire retardant 35 ~ 40%, softening agent 2 ~ 3%, bleeding agent 0.1 ~ 0.2%, remaining is aqueous solvent, and the fire retardant is the polymer of tetramethylol chloride and urea, described Softening agent is polyethylene based polymers, and preferably described softening agent is polyethylene emulsion, and the bleeding agent is fatty alcohol polyoxy second Alkene ether, the fire retarding treating liquid further include acetic acid, and the concentration of the acetic acid is 0.2 ~ 1g/L, its percentage by weight for 0.02 ~ 0.1%。
Before the all-cotton knitting cloth carries out the ammonia cure processing step, that detects the all-cotton knitting cloth contains tide Rate, make the all-cotton knitting cloth after being handled by the low temperature preliminary drying containing damp rate control 12 ~ 14%, adjust described complete For cotton knitting cloth by the speed of low temperature preliminary drying process, reach control all-cotton knitting cloth contains damp rate.When the all-cotton knitting When cloth contains damp rate 12 ~ 14% after the processing of low temperature preliminary drying, cloth can be only achieved the technological requirement of drying and shaping, can just make The color of cloth reaches sizing, carries out ammonia cure again afterwards, and the color of fabric will not produce change.
