Problems solved by technology

[0002] Generally, the amount of moisture crosslinking resin used in the moisture crosslinking finishing process is high and the fabric needs to be rolled and stacked for 24 hours. The processing cost of the fabric is high, the stacking time is long, the hand feels slippery and hard, and it is not easy to bond when sewing and lining Strong; the traditional wet crosslinking finishing fabric is crosslinked under the wet state, and the dry anti-wrinkle effect is poor. The present invention creatively improves the above wet crosslinking process to improve the non-ironing property

Embodiment 1

[0024] Blue Oxford yarn-dyed fabric: the warp and weft yarns are made of pure cotton 80s two strands, the warp density is 160 threads / inch, and the weft density is 72 threads / inch.

[0025] The production process is: singeing → desizing → mercerizing → liquid ammonia → pre-softening → wet cross-linking rolling → wet cross-linking → baking → primary washing → secondary washing → tenter → finished product inspection.

[0026] Singeing and desizing process: It is carried out on the combined burner and desizing machine. Singeing is used for singeing. The flame intensity is 14mbar. The front and back sides of the fabric are singed, the back side first and then the front side. Enzyme desizing is used for desizing. Desizing enzyme The dosage is 15g / L.

[0027] Mercerizing process: conventional mercerizing finishing is adopted, the concentration of mercerizing lye is 26 degrees Baume, and the pH value of the yarn-dyed fabric after mercerizing is 6.9.

[0028] Liquid ammonia process: ...

Embodiment 2

[0037] Plain yarn-dyed fabric with thin blue stripes on white background: use pure cotton 40s yarn in the warp direction, use pure cotton 30s yarn in the weft direction, the density in the warp direction is 120 threads / inch, and the density in the weft direction is 65 threads / inch.

[0038] The production process is: singeing → desizing → mercerizing → liquid ammonia → pre-softening → wet cross-linking rolling → wet cross-linking → baking → primary washing → secondary washing → tenter → finished product inspection.

[0039] Singeing and desizing process: It is carried out on the combined burning and desizing machine. Singing is used for singeing, and the flame intensity is 12mbar. The front and back sides of the fabric are singed, the back side is first, and the front side is desizing. Enzyme desizing is used for desizing. Desizing enzyme The dosage is 10g / L.

[0040] Mercerizing process: conventional mercerizing finishing is adopted, the concentration of mercerizing lye is 24...

Embodiment 3

[0050] Small purple plaid 2 / 1 twill yarn-dyed fabric: use pure cotton 50s yarn in the warp direction, use pure cotton 100s two-ply yarn in the weft direction, the warp direction density is 140 threads / inch, and the weft direction density is 90 threads / inch.

[0051] The production process is: singeing → desizing → mercerizing → liquid ammonia → pre-softening → wet cross-linking rolling → wet cross-linking → baking → primary washing → secondary washing → tenter → finished product inspection.

[0052] Singeing and desizing process: It is carried out on the combined burning and desizing machine. Singing is used for singeing, and the flame intensity is 13mbar. The front and back sides of the fabric are singed, the back side is first, and the front side is desizing. Enzyme desizing is used for desizing. Desizing enzyme The dosage is 12g / L.

[0053] Mercerizing process: conventional mercerizing finishing is adopted, the concentration of mercerizing lye is 23 degrees Baume, and the p...

Abstract

The invention belongs to the technical field of textile dyeing and finishing, and particularly relates to a processing method for improving easy-care performance of a moist crosslinking finishing yarn-dyed fabric. The processing method comprises the steps of singeing, desizing, mercerizing, liquid ammonia, pre-softening, moist crosslinking rolling, moist crosslinking, baking, primary washing, secondary washing, tentering and finished product inspection and packaging. Baking is carried out with a baker at a baking temperature of 120 to 140 DEG C for 3 to 5 minutes. According to the invention, two crosslinking is creatively adopted, the water shrinkage and heat shrinkage of a fabric are more stable, a pre-shrinking process is omitted, and thus the production cost of the fabric is reduced; the baking process is introduced into the moist crosslinking finishing process, and the time of moist crosslinking finishing piling is shortened by 6 to 12 hours, and the usage amount of resin and a catalyst is reduced by 20% to 50% compared with a traditional moist crosslinking process; the easy-care performance of the moist crosslinking finishing yarn-dyed fabric is enhanced by 0.2 to 0.5 grade, the fabric can be washed for 50 times, the easy-care degree is 4.0 or above.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and in particular relates to a processing method for improving the non-ironing property of moisture-crosslinked and finished yarn-dyed fabrics. Background technique [0002] Generally, the amount of moisture crosslinking resin used in the moisture crosslinking finishing process is high and the fabric needs to be rolled and stacked for 24 hours. The processing cost of the fabric is high, the stacking time is long, the hand feels slippery and hard, and it is not easy to bond when sewing and lining Strong; the traditional wet crosslinking finishing fabric is crosslinked under the wet state, and the dry anti-wrinkle effect is poor. The present invention creatively improves the above wet crosslinking process to improve the non-ironing property. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a p...
