Embodiment 1

[0038] The present invention proposes a durable flame-retardant non-ironing finishing liquid and a finishing method, and the specific steps are as follows:

[0039] Select pure cotton plain weave fabric, which is pretreated by desizing and bleaching, with a linear density of 7.29tex×2×7.29tex×2, a warp and weft density of 472 threads / 10cm×276 threads / 10cm, and an area density of 110g / m2. The breaking strength was 591 N, the crease recovery angle was 156° and the whiteness was 72.3.

[0040] (1) The preparation process of the finishing solution: Diethylene triamine pentamethylene phosphoric acid 20g / L, ammonium dihydrogen phosphate 40g / L, dicyandiamide 40g / L, urea 20g / L, penetrant 2g / L, softener 20g / L was prepared to obtain the finishing solution.

[0041] (2) Padding process: arrange the pure cotton plain weave in (1) finishing solution for two dipping and two rolling, and the excess rolling rate is 80%.

[0042] (3) Post-treatment process: After the pure cotton plain cloth ...

Abstract

The invention discloses a durable flame-retardant non-ironing finishing liquid and a finishing method, and belongs to the technical field of functional finishing of cotton fabrics. According to the durable flame-retardant non-ironing finishing liquid and the finishing method, dicyandiamide, a penetrating agent, a softening agent, a polyethylene raw material and a polybasic phosphate group mixed finishing liquid are dehydrated under the action of a catalyst to form a phosphoric anhydride bond, the phosphoric anhydride bond reacts with hydroxyl on cellulose, and the non-ironing and flame-retardant properties of a fabric are improved.

Description

technical field [0001] The invention relates to the technical field of functional finishing of cotton and cotton fabrics, in particular to a durable flame-retardant and non-ironing finishing liquid and a finishing method. Background technique [0002] The existing flame-retardant non-ironing finishing mainly finishes the cellulose by adding two kinds of finishing agents, flame-retardant and non-ironing, to the finishing solution to obtain the performance of flame-retardant and non-ironing. Elements can improve the flame retardant performance of finished fabrics, but the effect is not ideal, and additional flame retardants need to be added (academic paper: Research on the non-ironing finishing process of cotton fabrics with phosphorus-based polycarboxylic acids); the patent number is 201611191152.X published A flame-retardant and breathable non-iron finishing liquid for shirts and its finishing method. The prescription liquid formula is complicated, the cost is high, it is no...
