Problems solved by technology

[0003] There are certain deficiencies in the above method: due to the characteristics of large specific surface area and large specific surface energy, nano-zinc oxide itself is easy to agglomerate; Causes interface defects, leading to degradation of material properties
Adding adhesives will cause the fabric to have problems such as hard hand feeling, poor air permeability, poor washing fastness, and poor functional durability.

Embodiment 1

[0020] This example provides a method for preparing in-situ nano zinc oxide antibacterial and anti-ultraviolet textiles.

[0021] Preparation of the finishing solution: prepare 100ml mass percent of 0.4% amino-terminated hyperbranched compound aqueous solution (synthesized by diethylenetriamine and acrylic acid) and 0.01mol / l Zn(NO 3 ) 2 of the mixture.

[0022] Cotton fabrics were put into the mixed solution with a bath ratio of 1:50, and oscillated and reacted in a constant temperature water bath at 60°C for 20 minutes, then heated up to 100°C at a rate of 2°C / min, oscillated at a constant temperature for 2 hours, and the fabric was taken out, washed and dried to obtain nano ZnO antibacterial and antibacterial agents. UV cotton fabric.

[0023] See attached figure 1 , which is the SEM image of in-situ generated nano-ZnO on the surface of cotton fabric fibers provided in this example. It can be seen from the figure that there are a large number of tiny nano-ZnO particles ...

Embodiment 2

[0025] Cotton fabric modified amino-terminated hyperbranched compound treatment: the cotton fabric was dipped in an aqueous solution of 0.6% modified amino-terminated hyperbranched compound for 20 minutes. The preparation method of the modified amino-terminated hyperbranched compound is: get 1g of dodecanoic acid and add it to 20g of the amino-terminated hyperbranched compound synthesized by diethylenetriamine and methyl acrylate and 10ml of methanol solution, move to the rotary evaporator after dissolving, and heat up The polycondensation reaction is carried out at 150° C. to obtain a modified amino-terminated hyperbranched compound. The modified amino-terminated hyperbranch has a larger molecular weight and a long-chain structure, and has stronger adsorption to fibers.

[0026] The above-mentioned cotton fabric loaded with modified amino-terminated hyperbranched compound, in the ZnCl of 0.05mol / L 2 Immerse in the solution, steam for 10 minutes after taking it out, wash with...

Embodiment 3

[0032] Place 52m1 polyamino compound divinyltriamine in a 250m1 three-necked flask, cool in an ice-water bath, and place in N 2 Under protection, use a constant pressure funnel to slowly add a mixed solution of 43m1 methyl acrylate and 100m1 methanol dropwise, and react at room temperature for 4 hours after the dropwise addition to obtain light yellow transparent AB 2 and AB 3 type monomer. Then it was transferred to a rotary evaporator eggplant-shaped flask, methanol was removed under reduced pressure, the temperature was raised to 150°C to continue the reduced-pressure reaction for 4 hours, and the reaction was stopped to obtain a viscous light yellow amino-terminated hyperbranched compound. Dissolve 4 g of the obtained amino-terminated hyperbranched polymer in 50 ml of chloroform, add 7 g of poly(ethylene glycol) methyl ether acrylate, stir at room temperature for 12 h, then heat to 50° C. and stir for 12 h, and vacuum-dry to obtain the modified Amino-terminated hyperbran...

Abstract

The invention discloses a preparation method of an anti-bacterial ultraviolet-resistant textile. The textile is placed into finishing liquor prepared from an aqueous solution containing an amino-terminated hyperbranched polymer or a modified amino-terminated hyperbranched polymer and zinc salt for dipping treatment to obtain the anti-bacterial ultraviolet-resistant textile. Or the textile is soaked in the aqueous solution containing the amino-terminated hyperbranched polymer or the modified amino-terminated hyperbranched polymer, and then is subjected to dipping treatment in a zinc salt solution, to obtain the anti-bacterial ultraviolet-resistant textile. After being finished by using the method, the textile is good in hand feeling, air permeability and washing fastness, and good in anti-bacterial and ultraviolet-resistant function durability. By adopting an in-situ one-step generation process, the method is simple and easy in operation.

Description

technical field [0001] The invention relates to a method for antibacterial and anti-ultraviolet finishing of textiles, belonging to the technical field of textile post-finishing. Background technique [0002] Nano zinc oxide (ZnO) particle size ranges from 1 to 100 nm. It is a new type of high-performance fine inorganic product with quantum size effect, small size effect, surface effect, and macroscopic quantum tunneling effect. Zinc oxide can be used in the textile field to prepare textiles with functions such as ultraviolet light shielding, antibacterial, antistatic, and electromagnetic shielding. At present, there are two main finishing methods for nano-ZnO finishing fabrics. One is to use the melt blending method to directly add ZnO nano-powder treated with titanate coupling agent to the initial reaction solution or spinning solution of chemical fibers. The functional fibers are spun into functional fibers by conventional spinning technology; the other is the use of pos...
