[0046] 1. Desizing: use open width desizing machine. The temperature of the desizing tank is 98°C; the running speed of the fabric is 30m / min, and the processing time is 3min.

[0047] The formula of the treatment solution is based on the mass of each component per liter of water: liquid caustic soda 240g / L, refining agent 50g / L, penetrant 16g / L, chelating dispersant 8g / L. After desizing treatment, the residual size rate is 1.7%.

[0048] 2. Calendering treatment: High-temperature and high-pressure double-roll calender is used, the fabric running speed is 35m / min, and the pressure is 80kg / m 2 , the temperature is 160°C.

[0049] 3. Coating finishing: Floating knife coating at room temperature...

Embodiment 2

[0055] 1. Desizing: use open width desizing machine. The temperature of the desizing tank is 100°C; the running speed of the fabric is 27m / min. The formula of the treatment liquid is based on the mass of each component per liter of water: liquid caustic soda 260g / L, penetrant 19g / L, refining agent 55g / L, chelating dispersant 10g / L. After desizing treatment, the residual pulp rate is 1.1%

[0056] 2. Calendering treatment: high temperature and high pressure calendering machine is adopted, the fabric running speed is 30m / min, and the pressure is 100kg / m 2 , the temperature is 170°C.

[0057] 3. Coating finishing: Floating knife coating at room temperature is adopted, the fabric running speed is 25m / min, and the baking temperature is 170°C. The front side of the cloth is coated with finishing agent A, and the reverse side of the cloth is coated with finishing agent B.

[0058] The components of the finishing solution and their contents in parts by weight are: finishing agent ...

Embodiment 3

[0062] 1, desizing: with embodiment 2. The residual pulp rate after desizing treatment is 1.2%

[0063] 2. Calendering treatment: high temperature and high pressure calendering machine is adopted, the fabric running speed is 23m / min, and the pressure is 90kg / m 2 , the temperature is 168°C.

[0064] 3. Coating finishing: the fabric running speed is 32m / min, and the baking temperature is 165°C.

[0065] The components of the finishing liquid and their contents in parts by weight are: finishing agent A has a viscosity of 20000 cps and 88 parts of polyurethane resin with a solid content of 31%; solvent A is 6 parts of dimethylformamide; 4 parts of isocyanate; 1 part of hypophosphorous acid parts; 1 part of titanium dioxide. Finishing agent B: 84 parts of organopolysiloxane and hydrophilic polysiloxane resin mixture; Solvent B: 11 parts of toluene; 2 parts of isocyanate; 3 parts of sodium dihydrogen phosphate.

[0066] The preparation process of the finishing liquid is as follo...

Abstract

In order to overcome the defects that a nylon superfine denier fiber fabric is easy to degum and low in hydrostatic pressure resistance value, washing resistance and tear strength, clothes are not stiff and smooth enough, and gel easily permeates a coating and is easily adhered to the coating reversely when the coating is treated in the prior art, the invention provides a finishing agent for the nylon superfine denier fiber fabric and a preparation method for the finishing agent. The finishing agent consists of a finishing agent A and a finishing agent B, wherein the finishing agent A consists of the following components in part by weight: 86 to 90 parts of polyurethane resin, 4 to 8 parts of solvent A, 3 to 6 parts of bridging agent, 1 to 2 parts of accelerator and 2 to 4 parts of titanium dioxide; and the finishing agent B consists of the following components in part by weight: 81.5 to 92.5 parts of silicon resin, 3 to 11 parts of solvent B, 2 to 5 parts of cross-linking agent and 2 to 5 parts of cross-linking catalyst. The tear resistance, ultraviolet resistance, hydrostatic pressure resistance and stiffness and smoothness of the fabric treated by the finishing agent are obviously improved.

Description

technical field [0001] The invention relates to a finishing agent for nylon superfine denim fiber fabrics and a preparation method of the finishing agent. Background technique [0002] With the rapid development of social economy and the continuous improvement of people's material life, people have higher and higher requirements for outdoor leisure sportswear. Those heavy and monotonous clothing can no longer meet people's requirements. As consumers have higher and higher requirements for clothing comfort and personalization, nylon superfine denim fiber fabrics have emerged as the times require. Nylon ultra-fine denim fiber fabric has been widely used in outdoor leisure clothing because of its light weight, wear resistance, no insects, easy care and other excellent characteristics that natural fiber fabrics cannot match. [0003] Nylon ultra-fine denier fabric generally refers to the fabric whose yarn denier number is less than or equal to 20 denier. At present, there are ...
