High-grade non-ironing finishing method of deep black pure cotton fabric

Abstract

The invention belongs to the technical field of textile printing and dyeing and particularly relates to a high-grade noniron finishing method of deep dark pure cotton fabric, comprising the sequentialsteps of spread-sewing, singeing, desizing, scouring, mercerizing, cold pad-batch dyeing, high temperature soaping, liquid ammonia finishing, pre-softening, primary pre-shrinking, noniron treating, curing, water washing, tentering and softening, and secondary pre-shrinking, wherein curing temperature is 120-130 DEG C, curing reaction time is controlled to 5-6 min, and the noniron step employs padding AP resin noniron aid. The high-grade noniron finishing method of deep dark pure cotton fabric has the advantages that radial stretch of the fabric can be improved, noniron state is retained afternoniron curing, and noniron property of the fabric can be improved accordingly; the deep dark pure cotton fabric is imparted good softness, breathability and moisture absorption and good washing fastness, never fades in long-term standing, has good ironing firmness, is suitable for batch production, and reaches grade 3.8 and above under AATCC-125 standard in terms of noniron property.

Description

technical field

[0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a high-grade non-ironing finishing method for dark black pure cotton fabrics. Background technique

[0002] With the growing call of human beings to return to nature, people's demand for natural fiber clothing fabrics is gradually increasing. Cotton, as one of the representatives of natural fibers, has natural and comfortable properties, so it is more and more favored by people. However, pure cotton fabrics are easy to wrinkle, and the shrinkage after washing is not easy to control, so the anti-wrinkle finishing of pure cotton fabrics is particularly important. At present, almost all non-ironing finishing uses resin dipping, drying, and then drying at 140-150°C Baking under high temperature conditions, or moist cross-linking and padding resin stacking under normal temperature and strong acidic conditions to achieve a high-level non-ironing finishi...

Examples

Embodiment 1

[0027] The fabric weave specification is CM40*CPT60 / 2*114*65*60 / 61 plain fabric, dark black.

[0028] The non-iron finishing process of fabrics is: seaming → singeing → desizing → scouring → mercerizing → cold pad-batch dyeing → high-temperature soaping → liquid ammonia finishing → pre-softening → first pre-shrinking → non-ironing → baking → Washing → tenter softness → second pre-shrinking.

[0029] The processing technology of each process is as follows:

[0030] 1. Singeing: speed 120m / min, normal burning, flame intensity 18mbar.

[0031] 2. Desizing: speed 70m / min, desizing enzyme 3g / L, penetrant 3g / L, and the rest is water; steamer temperature 95°C, stack for 15min, wash with 4 compartments at 95°C.

[0032] 3. Scouring: NaOH 40g / L, refining agent 6g / L, penetrant 6g / L, chelating agent 3g / L, the rest is water; speed 70m / min, steam at 100°C for 30min, wash with water at 95°C in 4 compartments.

[0033] 4. Mercerizing: the concentration of mercerizing is 220g / L.

Embodiment 2

[0046] The fabric weave specification is CM50*CPT40*133*80*61 / 62 plain fabric, dark black.

[0047] The non-iron finishing process of fabrics is: seam spreading → singeing → desizing → scouring → mercerizing → cold pad-batch dyeing → high temperature soaping →

[0048] Liquid ammonia finishing → pre-softening → first pre-shrinking → non-ironing → baking → washing → tenter softening → second pre-shrinking.

[0049]The processing technology of each process is as follows:

[0050] 1. Singeing: speed 120m / min, normal burning, flame intensity 18mbar.

[0051] 2. Desizing: speed 70m / min, desizing enzyme 3g / L, penetrant 3g / L, steamer temperature 95°C, the rest is water; stack for 15min, wash with 4 grids at 95°C.

[0052] 3. Scouring: NaOH 40g / L, refining agent 6g / L, penetrant 6g / L, chelating agent 3g / L, the rest is water; speed 70m / min, steam at 100°C for 30min, wash with water at 95°C in 4 compartments.

[0053] 4. Mercerizing: the concentration of mercerizing is 210g / L.
