Problems solved by technology

The early color-fixing agents were cationic surfactants. The earliest color-fixing agents in China were dicyandiamide resins developed in the early 1950s. This kind of color-fixing agents would change the color of fabrics and reduce the color fastness to sunlight. , and contains free formaldehyde, which is harmful to the human body

Embodiment 1

[0037] (1) Put dimethyl diallyl ammonium chloride and diallyl amine into the flask according to the mass ratio of 100:13, then add 0.13g of ammonium persulfate initiator, and then add a certain amount of glacial acetic acid to adjust In an acidic environment, after mixing evenly, reflux, heat up to 65°C, stir with magnetic force, and react for 3 hours.

[0038] (2) Add 0.54 g of epichlorohydrin and continue the reaction for 0.5 hour to obtain a crosslinkable polycation.

[0039] (3) Add 25ml of deionized water, and magnetically stir for 10 minutes to obtain the product.

[0040] Such as figure 1 Shown, its infrared spectrogram of the obtained product shows 3342cm -1 The absorption peak is the stretching vibration peak of N-H; 1728cm -1 The absorption peak at shows the residue of diene group; 2972~2881cm -1 DescriptionCH 3 —,—CH 2 ———CH—The presence of the group proves that the polydimethyldiallylamine chloride product is generated.

Embodiment 2

[0042] (1) Put dimethyl diallyl ammonium chloride and diallyl amine into the flask according to the mass ratio of 100:14, then add 0.14g ammonium persulfate initiator, then add a certain amount of glacial acetic acid to adjust In an acidic environment, after mixing evenly, reflux, heat up to 65°C, stir with magnetic force, and react for 3 hours.

[0043](2) Add 0.54 g of epichlorohydrin and continue the reaction for 0.5 hour to obtain a crosslinkable polycation.

[0044] (3) Add 25ml of deionized water, and magnetically stir for 10 minutes to obtain the product.

Embodiment 3

[0046] (1) Put dimethyl diallyl ammonium chloride and diallyl amine into the flask according to the mass ratio of 100:9, then add 0.09g of ammonium persulfate initiator, and then add a certain amount of glacial acetic acid to adjust In an acidic environment, after mixing evenly, reflux, heat up to 65°C, stir with magnetic force, and react for 3 hours.

[0047] (2) Add 0.54 g of epichlorohydrin and continue the reaction for 0.5 hour to obtain a crosslinkable polycation.

[0048] (3) Add 25ml of deionized water, stir magnetically for 10min, and obtain the product, such as figure 2 As shown, it was proved that polydimethyldiallylamine chloride product was generated.

Abstract

The invention discloses a dimethyldiallylammonium chloride polymer, and a preparation method and an application thereof. A copolymer is synthesized through a polymerization reaction of dimethyldiallylammonium chloride, diallyl amine and an initiator which are used as raw materials, and a cross-linking agent is added to obtain the novel polycationic perspiration-resistant color fixing agent. The copolymer reacts with an anionic dye used by superfine fiber PU leather to generate color lake, and a formed polymer reticular structure forms a film on the surface of the leather to coat the dye and fiber, so that the perspiration-resistant color fastness of the leather is improved. The color fixing agent prepared in the invention has the advantages of no use of an organic solvent in the productionprocess, greenness, environmental friendliness, no formaldehyde, excellent perspiration resistance and good stability, and the preparation method has the advantages of simplicity, short time, low energy consumption, and provision of an important guarantee for industrial production.

Description

technical field [0001] The invention relates to the field of polymers, in particular to a polydimethyldiallylamine chloride polymer, a preparation method thereof, and an application of a color fixing agent, which are applied to the field of subsequent treatment of ultrafine fiber PU leather fabrics, and are suitable for a superfine fiber PU leather fabric. Polycationic perspiration-resistant color-fixing agent for fine fiber PU leather, its preparation method and its application. Background technique [0002] Sweat stains have a significant effect on fabric fading. However, there are few dye-fixing agents specifically for sweat stains in the market, and the effect is good. Especially the blisters fade seriously. Based on the above reasons, our research group invented a new color fixing agent that can resist sweat stains and effectively improve the effect of blisters. After consulting relevant literature, no similar synthesis method has been found. [0003] After the micro...
