Embodiment 1

[0027] The preparation process of the waterproof and flame-retardant polyamide fiber fabric includes: pre-treatment process and printing, waterproof and flame-retardant layer coating process.

[0028] Among them, the parameters in each step are set as follows:

[0029] During cold pad-batch treatment, use 40g / L caustic soda and 8g / L hydrogen peroxide to pad the gray cloth. After padding, roll and stack it for 12 hours. The gray cloth is a thick sparse fabric above 1000D.

[0030] When scouring, first carry out immersion, and then carry out steaming. Among them, the immersion method is five immersion and five rolling, the liquid carrying rate is 80%, and the tension of the washing machine is set to 4Mpa; the auxiliaries of the immersion liquid include desizing and refining agent YZ-1118, chelating agent, caustic soda, hydrogen peroxide, and water glass. The concentration of desizing and scouring agent is 4g / L, the concentration of chelating agent is 2g / L, the concentration of ...

Embodiment 2

[0046] The difference between this embodiment and embodiment 1 is that only caustic soda is used during the cold pad batch in the present embodiment;

[0047]The immersion method during scouring is five immersion and five rolling, and the additives for immersion are desizing and scouring agent YZ-1118, caustic soda, hydrogen peroxide, wherein the concentration of desizing and scouring agent is 5g / L, and the concentration of caustic soda is 20g / L. The concentration of hydrogen peroxide is 12g / L; the speed of steaming is 50m / min, the time is 60min, and the temperature is 70°C; the liquid carrying rate after padding is 60%; the tension of the washing machine is 4MPa;

[0048] When setting the shape, the vehicle speed is 80m / min, and the temperature is 220°C.

Embodiment 3

[0050] The difference between this embodiment and Embodiment 1 lies in that the concentrations of caustic soda and hydrogen peroxide used during cold pad batching in this embodiment are different, the contents of additives in the immersion solution are different, and the temperature and vehicle speed are different during shaping. The specific settings are as follows:

[0051] Adopt concentration during described cold pad batch to be that the caustic soda of 35g / L and the hydrogen peroxide of 9g / L carry out padding to gray cloth;

[0052] During scouring, five immersion and five rolling methods are used to immerse the liquid, and then steam; the auxiliary agents for the immersion liquid include desizing and scouring agent, chelating agent, caustic soda, hydrogen peroxide, and water glass, wherein the concentration of the desizing and scouring agent is 3g / L, the concentration of chelating agent is 3g / L, and the concentration of caustic soda is 8g / L, and the concentration of hyd...

Abstract

The invention discloses a preparation process of a waterproof flame-retardant polyamide fiber fabric, which solves the problem in the prior art that a pretreatment way capable of well ensuring the dyeing effect of synthetic fiber fabric cannot be found. The preparation process comprises a pretreatment process and a printing and waterproof flame-retardant layer coating process, wherein the pretreatment process comprises the following steps: cold rolling a gray fabric, boiling the fabric, and stereotyping the fabric, wherein when in cold rolling, caustic soda with the concentration of 35 to 45 g/L and hydrogen peroxide with the concentration of 6 to 10 g/L are used for padding the gray fabric; when in boiling, the immersion is performed in a five-time immersing and five-time rolling manner,and then the fabric is steamed; immersion additives comprise a desizing refining agent, a chelating agent, caustic soda, hydrogen peroxide and water galss, wherein the concentration of the desizing refining agent is 3 to 5 g/L, the concentration of the chelating agent is 1 to 3 g/L, the concentration of the caustic soda is 8 to 12 g/L, the concentration of the hydrogen peroxide is 4 to 6 g/L, andthe concentration of the water glass is 4 to 6 g/L; and when in the stereotyping, the speed is 85 to 95 m/min, and the temperature is 180 to 200 DEG C. The preparation process has the advantages of good dyeing effect, more stability in adhesion of a waterproof flame-retardant layer and the like.

Description

technical field [0001] The invention relates to the field of textile manufacturing, in particular to a preparation process of a waterproof flame-retardant polyamide fiber fabric. Background technique [0002] Synthetic fibers and their fabrics, such as carpets, curtains, upholstery, etc., are the necessities of people's daily life. However, due to their flammability, they often bring disasters to us. The United States and Europe put forward strict heat insulation and fire prevention requirements for automotive interiors, aircraft interiors, home textiles, special labor protective clothing, and military uniforms. From the long-term trend, the demand for flame retardant is one of the basic needs in daily life. [0003] Domestic dyeing and finishing methods of flame-retardant fabrics are mainly considered from two aspects: one is to use flame-retardant fibers, such as aramid, sulfonamide, ceramic fibers, and fabrics woven from flame-retardant viscose fibers. The second is to...
