Description

Processing method of anti-yellowing nylon fabric
Technical Field
The invention relates to a processing method of anti-yellowing nylon fabric, and belongs to the field of functional textile fabrics.
Background
The nylon fiber is prepared by taking polyamide as a raw material and carrying out melt spinning and post-processing. The nylon fiber has high strength, good elasticity, better performances of tensile strength, tensile impact, bending strength, fatigue resistance and the like at normal temperature, and also has better oil resistance, wear resistance, chemical resistance, electrical performance and other performances. Owing to the excellent physical and mechanical properties, nylon is increasingly used in the textile field.
Nylon has poor heat resistance and light resistance, and can cause molecular oxidative cleavage by long-term exposure in sunlight, and the sunlight or ultraviolet irradiation causes the surface of textiles to be yellow, namely the phenomenon of photoyellowing of nylon fabric.
Disclosure of Invention
The invention aims to provide a processing method of anti-yellowing nylon fabric, which is characterized in that an ultraviolet-resistant substance is applied to the surface of the nylon fabric so as to weaken yellowing caused by ultraviolet irradiation.
In order to achieve the above purpose, the present invention adopts the following technical scheme.
A processing method of anti-yellowing nylon fabric comprises the following steps:
s1, immersing nylon fabric into quaternary ammonium salt silicone resin emulsion;
S2, immersing the nylon fabric into nano silicon dioxide sol;
S3, padding waterproof emulsion on the fabric, and drying;
the preparation method of the quaternary ammonium salt silicone resin emulsion comprises the following steps:
Weighing quaternary ammonium salt type organic siloxane shown in formula 1, benzophenone-containing siloxane, deionized water and trace potassium hydroxide, adding into a reactor, mixing, heating to 75 ℃ for constant-temperature hydrolytic condensation reaction for 4 hours, vacuumizing for 1 hour to remove low-boiling substances to obtain quaternary ammonium salt type silicon resin, uniformly mixing water and an emulsifying agent, adding the quaternary ammonium salt type silicon resin, stirring and emulsifying, and adding acetic acid to adjust the pH value to be neutral to obtain transparent quaternary ammonium salt type silicon resin emulsion.
The preparation method of the quaternary ammonium salt type organosiloxane comprises the steps of weighing 23.5g of dodecyl dimethyl tertiary amine in a reactor, adding 40mL of isopropanol for dissolution, protecting nitrogen, adding 23.6g of gamma-glycidol ether oxypropyl trimethoxy silane and 6.6g of glacial acetic acid, stirring at 75 ℃ for reaction for 6 hours, and removing isopropanol and impurities by rotary evaporation to obtain the quaternary ammonium salt type organosiloxane.
In the processing method of the anti-yellowing nylon fabric, step S1, the nylon fabric is immersed in quaternary ammonium salt silicone resin emulsion for 10min, taken out and dried.
According to the processing method of the anti-yellowing nylon fabric, the S2 nylon fabric is immersed in nano silicon dioxide sol for 5min, taken out and dried.
The waterproof emulsion is prepared by emulsion polymerization of vinyl silicone oil, acrylic ester, an emulsifying agent, water and an initiator.
In the processing method of the anti-yellowing nylon fabric, in the step S3, the drying method is that the nylon fabric is dried for 3min at 100 ℃ and baked for 2min at 160 ℃.
The nylon fabric is woven by warps and wefts, wherein the warps and the wefts are nylon elastic cladding yarns.
The nylon fabric is treated by deoiling and refining:
The nylon fabric is put into pretreatment liquid (bath ratio is 1:10), is heated to 100 ℃ and is subjected to heat preservation for 30min, is cooled and is washed by water, wherein the pretreatment liquid contains 3g/L NaOH, 2g/L deoiling agent, 2g/L chelating dispersant and the balance of water.
According to the processing method of the anti-yellowing nylon fabric, after the nylon fabric is sequentially soaked in the quaternary ammonium salt silicone resin emulsion, the nano silicon dioxide sol and the waterproof emulsion, a good anti-yellowing function and a good waterproof performance are obtained. After the nylon fabric is immersed in the quaternary ammonium salt silicone resin emulsion, the cationic performance is presented, then the anionic nano silicon dioxide sol is immersed, and the electrostatic attraction between ions acts, so that the quaternary ammonium salt silicone resin emulsion and the nano silicon dioxide sol are tightly combined on the surface of the nylon fabric. If the nano silicon dioxide is fixed on the surface of the fabric only by the subsequent waterproof emulsion, the dosage is required to be additionally increased so as to keep good bonding fastness between the nano silicon dioxide and the fabric, but the hand feeling of the fabric is deteriorated by the large-scale application of the waterproof emulsion. The invention can reduce the application amount of the waterproof emulsion through the electrostatic effect, thereby ensuring the relative fastness and keeping the soft hand feeling of the fabric. The nano silicon dioxide can reflect and scatter ultraviolet rays, so that yellowing of the nylon fabric caused by the ultraviolet rays is reduced, and the anti-yellowing performance of the fabric is enhanced by cooperation with benzophenone in the quaternary ammonium salt silicone resin. The nano silicon dioxide and the waterproof emulsion applied to the surface layer of the nylon fabric form a lotus leaf-like hydrophobic surface, so that the fabric has good water splashing resistance. The benzophenone compound is a common ultraviolet resistant finishing agent for fabrics, but the organic compound can migrate and degrade in the process of taking the fabrics, so that the effect is weakened, and the benzophenone compound is connected into a macromolecular chain through chemical reaction, so that the stability of the compound can be improved.
