Embodiment Construction

[0016] The flame retardant finishing method of pure cotton knitted fabric is as follows. First, the pure cotton knitted fabric is pad-rolled with a flame-retardant finishing solution containing a flame retardant through a sizing machine, and then the pure cotton knitted fabric is pre-dried at 100-120 ° C; Ammonia fumigated cross-linking room, so that the ammonia gas and the flame retardant on the knitted fabric are fully and evenly cross-linked; then oxidized, washed and dried. The flame-retardant effect of the pure cotton knitted fabric obtained through the flame-retardant finishing process of the present invention is uniform in the front, back, left, and right sides, and has no color flower problem.

[0017] see figure 1 , the upper and front parts of the ammonia fumigated crosslinking chamber 13 are provided with a steam inlet 4, the front part is also provided with a hatch 5 for entering the ammonia fumigated crosslinking chamber, and the rear part is provided with an amm...

Abstract

The invention provides an ammonia-smoking method and a flame-proof treatment method for pure cotton knitted fabric. The flame-proof treatment method comprises the following steps: padding the pure cotton knitted fabric into a flame-proof treatment solution with a fire retardant by a setting machine, and performing pre-drying on the pure cotton knitted fabric at the temperature of 100-120 DEG C; leading the pure cotton knitted fabric to be in a natural suspension state to pass through an ammonia-smoking crosslinking chamber fully filled with ammonia, so that the ammonia can be fully crosslinked with the fire retardant on the knitted fabric evenly; and then performing oxidizing, washing and parching. In the invention, the pure cotton knitted fabric is in a natural loose suspension state to pass through the ammonia-smoking crosslinking chamber, thus the strain suffered by the pure cotton knitted fabric is small and can not cause the deformation and turned edges of the knitted fabric, the anti-flaming effects of the two sides of the shell fabric and the middle part of knitted fabric are the same, and the defect of colored spots can not appear.

Description

technical field [0001] The invention relates to a flame-retardant finishing process for pure cotton knitted fabrics, in particular to an ammonia fumigation method in the flame-retardant finishing process. Background technique [0002] PROBAN is a durable post-treatment flame retardant for cellulose fibers and their blended fabrics. Its main chemical component is tetrakishydroxymethylphosphorus chloride (THPC). The process of using PROBAN for flame-retardant finishing of fabrics is: [0003] Padding flame retardant finishing solution (room temperature)→pre-drying (100~120℃)→ammonia fumigation→oxidation, washing→drying (130~140℃). [0004] The flame retardant finishing method is also called the Proban method, which originated from the British Aowei Company. Specifically, the Proban method is to firstly pad the pure cotton knitted fabric with a flame retardant finishing solution containing a flame retardant through a sizing machine, and then pre-dry the pure cotton knitted fa...
