Abstract
The invention discloses a dyeing method of aromatic polyamide yarn, which comprises the following steps: inversing aromatic polyamide yarn into cylinder yarn; adding cylinder yarn in the color paste solution with leveler, cross linker and dye; keeping temperature at 70 deg.c for 30 min; stirring to heat temperature to 100-140 deg.c for 30-60 min; cooling to 70 deg.c; proceeding washing through 100 deg.c water for 20 min, 85 deg.c soap liquid for 20 min and 100 deg.c water for 30 min; drying dyed cylinder yarn at 85 deg.c for 20 min.
Description
Technical field
The invention belongs to the dyeing and finishing technique field, relate in particular to a kind of colouring method of aromatic polyamide yarn.
Background technology
The fabric of the said aromatic polyamide yarn of the present invention has outstanding heat-resisting, firing resistance, and 100 hours strength losses of heating are less than 5% in 300 ℃ of hot-airs.In addition, also have electrical insulating property and radiation resistance preferably, can be widely used in suit, flight ventilation clothing, special uniform, military paulin, fire-entry suit, turnout gear, stokehold Work Clothes, electric welding Work Clothes, forest Work Clothes, all force to submit, radiation proof Work Clothes, chemical protecting suit, high-tension shielding clothes, hotel be with knitting, the woven product of aspects such as textiles and escape and rescue trunk, fire screen, fire prevention gloves.Because the aromatic polyamide characteristic that is difficult to dye, make the dyeing of coloured aromatic polyamide fibre only consider to make dyestuff to anchor at method (patent CN91109377.X) in the fibrous material, aromatic polyamide yarn is not seen the report in the dyeing.
Summary of the invention
The technical problem that the present invention solves provides a kind of colouring method of aromatic polyamide yarn, is difficult to dyeing to overcome the aromatic polyamide that exists in the prior art, only considers to make dyestuff anchor at the defective of the method in the fibrous material, and cost greatly dyes.
Technical conceive of the present invention is such: be raw material with the aromatic polyamide yarn, adopt the mixing mill base of dye leveller, crosslinking agent and dyestuff to preset the constant temperature processing, to optimize washing process, obtain target product of the present invention.Therefore the feel of product, dye uptake, COLOR FASTNESS are achieved.
Method of the present invention may further comprise the steps successively:
1) doff: aromatic polyamide yarn is fallen a yarn;
2) dyeing: 70 ℃ of tube yarn inputs are contained in the mill base solution of dye leveller, crosslinking agent and dyestuff constant temperature 30 minutes; Be warming up to 100～140 ℃ in the stirring, kept 30～60 minutes; After being cooled to 70 ℃, washed 20 minutes with 100 ℃ water; The liquid of soaping with 85 ℃ carried out 20 minutes; Wash with 100 ℃ water and to go out cylinder after 30 minutes;
3) oven dry: tin yarn after will dye was with 85 ℃ of dryings 20 minutes.
Method according to above-mentioned is characterized in that, the mill base solution concentration is 0.01%～8%o.w.f.
Method according to above-mentioned is characterized in that, levelling agent concentration is 0.1g/l～5g/l in the mill base solution, and crosslinker concentration is 10g/l～120g/l.
Method according to above-mentioned is characterized in that, the concentration of washing agent is 2g/l～60g/l in the liquid of soaping.
The said product of the present invention is pressed GB18401-2001 and is measured content of formaldehyde, presses FZ/T73008-1997 and measures fastness to rubbing.Test through Shanghai textile printing and dyeing product quality prison inspection point with the product that colouring method of the present invention obtains: content of formaldehyde is below the 75ppm, and fastness to rubbing is more than 3 grades, reaches excellent index.
The invention solves that aromatic polyamide yarn exists in normal dyeing do not paint, the aberration problem; Make the aromatic polyamide fabric product after the dyeing soft, content of formaldehyde is low, and COLOR FASTNESS is up to state standards; Constant product quality is suitable for industrialized production, has good dyeability and Practical Performance.
