Embodiment 1

[0025] A polyamide fiber fabric, the specific preparation process includes: gray cloth→cloth turning→cold pad-batch→scouring→setting→dyeing→printing→baking→steaming→soaping→color fixing→waterproof tentering→ Calendering→reverse gluing tenter→calendering→inspection→finished product.

[0026] Among them, the parameters in each step are set as follows:

[0027] During cold pad-batch treatment, use 40g / L caustic soda and 8g / L hydrogen peroxide to pad-roll the gray cloth, and roll and stack it for 12 hours after pad-rolling.

[0028] 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 auxiliary agents for immersion 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 ...

Embodiment 2

[0042]The difference between this embodiment and Embodiment 1 is that the composition and proportioning of the waterproof finishing liquid in this embodiment are different, and the specific settings are as follows:

[0043] The mass ratio of the waterproofing agent DM-3680K, waterproofing agent DM-3665, waterproofing agent DM-1000 and waterproofing agent DTM648-2 is 2:2:1:1. The addition amount of magnesium chloride is 5.5g / L.

Embodiment 3

[0045] The difference between this embodiment and Embodiment 1 is that the composition and proportioning of the waterproof finishing liquid in this embodiment are different, and the specific settings are as follows:

[0046] The mass ratio of the waterproofing agent DM-3680K, waterproofing agent DM-3665, waterproofing agent DM-1000 and waterproofing agent DTM648-2 is 1:4:2:2. The addition amount of magnesium chloride is 4.5g / L.

Abstract

The invention discloses a waterproof finishing solution for a polyamide fiber fabric and a padding method of the polyamide fiber fabric. According to the waterproof finishing solution, the problem that a good waterproof way targeted for the polyamide fiber fabric is not available in the prior art is solved. The waterproof finishing solution is prepared from a waterproof agent DM-3680K, a waterproof agent DM-3665, a waterproof agent DM-1000 and a waterproof agent DTM648-2 of which the mass ratio is (1 to 2):(2 to 4):(1 to 2):(1 to 2); and the waterproof finishing solution is also prepared froma pH neutralizer and magnesium chloride, wherein the addition volume of the magnesium chloride is 4.5 to 5.5 g / L and the pH value of the waterproof finishing solution is 6 to 8. The waterproof finishing solution disclosed by the invention has the characteristics that fading after dyeing is avoided, and a flame-retardant coating can be better attached to the polyamide fiber fabric, so that the service life of the polyamide fiber fabric is prolonged; and the waterproof finishing solution has the advantages of improving waterproof effects, strength, durability and the like.

Description

technical field [0001] The invention relates to the field of textile manufacturing, in particular to a waterproof finishing solution for polyamide fiber fabrics and a padding method thereof. 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 ...
