Embodiment

[0024] Embodiment: each component of the embodiment product of the present invention is shown in Table 1.

[0025] Table 1: Formaldehyde-free low-damage anti-wrinkle finishing agent composition (unit: parts by weight)

[0026]

[0027] The finishing method of the fabric by the formaldehyde-free low-damage anti-wrinkle finishing agent of the present invention is to soak the fabric in a sodium citrate solution (0.5% in mass concentration) for 30 minutes at room temperature, take it out and drain it; The drying rate is 85%; drying at 90°C for 5 minutes; baking at 135°C for 2 minutes, followed by cold water washing and hot water washing respectively, followed by drying to complete the finishing process. The concentration of the finishing agent solution is 30-40g / L.

[0028] Fabric 1: linen fabric, five pieces of three-flying satin, the density is 340×340 threads / 10cm.

[0029] Fabric 2: linen / polyester interwoven fabric, five pieces of three-flying satin, the density is 340×3...

Abstract

The invention discloses a novel formaldehyde-free low-damage crease-resistant finishing agent and a finishing method thereof and belongs to the technical field of functionality design of textiles. The finishing agent comprises components in parts by weight as follows: 24-30 parts of waterborne polyurethane, 12-15 parts of sodium carboxymethyl cellulose, 5-8 parts of triethanolamine, 3-7 parts of 4,5-dihydroxyl ethylene urea, 0.1-0.5 parts of potassium benzoate and 0.1-0.2 parts of sodium sulfite. The invention further discloses a finishing method of the novel formaldehyde-free low-damage crease-resistant finishing agent for textiles. The novel formaldehyde-free low-damage crease-resistant finishing agent and the finishing method meet international requirements for environment-friendly textiles, the price is low, the finishing agent is efficient, costs are saved, meanwhile, the problem that textiles yellow and touch a little hard after being finished with common finishing agents is solved, and the finishing agent and the finishing method have good market popularization benefits and economic benefits.

Description

Technical field: [0001] The invention belongs to the technical field of textile functional design, and relates to a formaldehyde-free, low-damage anti-wrinkle finishing agent and a finishing method thereof. Background technique: [0002] Polyurethane, or polyurethane (PU), is a general term for polymers containing repeated carbamate groups (-NHCOO-) in their molecular structure. Water-based polyurethane is relative to solvent-based polyurethane. It is a binary colloid system in which polyurethane particles are dispersed in the continuous phase (water). Like ordinary polyurethane, it belongs to (AB)n type block polymer. Water-based polyurethane uses water as the main medium and contains no or only a small amount of organic solvents. According to different formulations and additives, it can be prepared as a treatment agent for many purposes. [0003] Polyurethane is used as a finishing agent for natural fiber fabrics and synthetic fabrics. It can adjust and improve the fullne...
