Claims (5)
1. The production process of the polyester fabric by the alkali deweighting and dyeing one-bath method is characterized by sequentially comprising the following steps of:
s1 alkali weight reduction treatment: placing the terylene fabric in 6-8% sodium hydroxide solution with a bath ratio of 1: 5-6; treating at 130-135 deg.C for 30-45 min;
s2 alkaline staining: cooling the treatment liquid in the last step to 50-60 ℃, adding 3-4% o.w.f of basic disperse dye, 4-5g/L of leveling agent and 15-20g/L of dispersing agent, heating to 110 ℃ at the heating rate of 0.5-1 ℃/min, adding 10-15g/L of polyester hyperbranched polymer, preserving the heat for 20-30min, and heating to 125 ℃ at 120 ℃;
s3 hot water washing: washing with 80-85 deg.C clear water;
s4 cold water washing: washing with 30-35 deg.C clear water.
2. The polyester fabric alkali-deweighting and dyeing one-bath production process as claimed in claim 1, wherein the dispersant used comprises 3-5 parts by mass of benzimidazole, 2-3 parts by mass of 2-ethyl methacrylate, 3-5 parts by mass of hydroxyethylidene diphosphonic acid, 1-2 parts by mass of HPMA, and 5-8 parts by mass of hydroxypropyl methacrylate.
3. The alkali-deweighting and dyeing one-bath production process of the polyester fabric as claimed in claim 1, wherein the polyester-based hyperbranched polymer at least comprises one of hyperbranched polyester quaternary ammonium salt, hyperbranched polyester polyol or hyperbranched unsaturated polyester.
4. The production process of the dacron fabric by the alkali deweighting and dyeing one-bath method as claimed in claim 1, wherein the leveling agent comprises 45-50 parts by mass of fatty alcohol oxyethyl ether, 20-30 parts by mass of sodium dihydrogen phosphate, 5-10 parts by mass of soluble rare earth chloride and 100 parts by mass of deionized water.
5. The alkali-deweighting and dyeing one-bath production process of the polyester fabric as claimed in claim 1, wherein 1-2% of soaping agent is added in the hot water washing step.
