Description
Technical Field
The invention relates to the field of fiber materials, in particular to a preparation method of a modified silk fabric with an ultraviolet-resistant function.
Background
Silk is a natural protein fiber with a structure similar to human skin. Due to its softness, affinity to the skin, high hygroscopicity and regenerative properties, many people love to wear silk clothing, and silk is widely used in the textile production industry. Despite the many advantages of silk, its protein properties may also present inherent drawbacks, such as photoaging, which greatly limit the widespread use of silk fabrics in luxury fashion garments, and therefore, it is highly desirable to produce silk fibers with uv protection.
With the development of nanotechnology, a number of nanomaterials with unique functions and structures have been synthesized. The multifunctional nano material modified silk can effectively endow silk fabrics with new performance. Zinc oxide and titanium dioxide nanoparticles have also found many applications in modified silk fibers. They not only provide antibacterial activity without changing the color of silk, but also have ultraviolet blocking ability to protect silk from light aging or yellowing, but zinc oxide and titanium dioxide nanoparticles are not very strong in absorbing ultraviolet rays, and as people's requirements for silk fabrics increase, we must develop silk with higher ultraviolet resistance.
Disclosure of Invention
In order to solve the technical problems, the invention provides a preparation method of a modified silk fabric with an ultraviolet resistance function. The modified silk fabric prepared by the invention has excellent ultraviolet resistance, and meanwhile, the modified silk fabric has excellent hand feeling, and cerium oxide nano particles are not easy to fall off.
The specific technical scheme of the invention is as follows:
a preparation method of a modified silk fabric with an anti-ultraviolet function comprises the following steps:
(1) preparing cerium oxide nanoparticle sol by adopting a hydrolysis method: adding Ce (NO)3)3·6H2Dissolving O in ethanol, and violently stirring to obtain a nitrate solution; slowly adding a sodium hydroxide ethanol solution into the nitrate solution, heating and stirring, filtering and collecting cerium oxide nanoparticles; washing with water and ethanol in sequence; finally dispersing the product into water to prepareObtaining the cerium oxide nano-particle sol.
(2) Degumming the silk fabric: the silk fabric is soaked in a sodium carbonate solution for degumming, then taken out and washed by water, and the process is repeated for a plurality of times to completely remove sericin in the surface of the silk fabric. The silk is one of natural protein fibers, and the fibers are of a skin-core structure, wherein the core layer is silk fibroin, and the skin layer is a sericin layer. Sericin has a certain protection effect on silk fibroin, but if the content of sericin is too large, the luster and the hand feeling of silk fibroin and the technological processing of silk are affected, and impurities such as grease and wax bring certain difficulty to the post-processing. Therefore, before processing, the invention needs to remove most of impurities such as sericin, grease, wax and the like to make the silk soft, loose and clean.
(3) Dipping treatment: and (3) soaking the silk fabric obtained in the step (2) in cerium oxide nanoparticle sol, taking out and drying the silk fabric, and curing the silk fabric to obtain the silk fabric with cerium oxide nanoparticles attached to the surface.
(4) And (4) adding PDMS (polydimethylsiloxane) into isopropanol to dissolve, uniformly stirring to obtain a PDMS solution, soaking the silk fabric obtained in the step (3) into the PDMS solution, extruding by using a padding machine, taking out and drying, and finally curing to obtain the modified silk fabric with the ultraviolet resistance function.
Rare earth metal oxide CeO2The nano particles have good uvioresistant performance, and a layer of CeO is attached to the surface of the silk fabric2The nano particles can effectively improve the uvioresistant performance of the silk fabric. However, the group of the present invention found in the experimental process that although CeO was used2The nano particles can effectively improve the ultraviolet resistance of the silk fabric, but the surface smoothness of the silk fabric is greatly reduced after the nano particles are attached, and the hand feeling is seriously influenced. Therefore, the invention further applies a transparent PMDS film with high flexibility and elasticity on the surface of the silk fabric, which not only can effectively improve the hand feeling of the silk fabric, but also can improve the CeO2The nano particles are covered on the surface to prevent the nano particles from falling off (otherwise, CeO2The nanoparticles are easily exfoliated under the influence of external forces). In addition, because the Polydimethylsiloxane (PDMS) film has transparency, CeO is not influenced2The ultraviolet resistance of the nano particles.
Preferably, in the step (1), the Ce (NO) is3)3·6H2The mass ratio of O and ethanol is 1: 15-25, and the vigorous stirring temperature is 55-65 ℃.

Preferably, in the step (1), the content of the cerium oxide nanoparticles in the cerium oxide nanoparticle sol is 8 to 12%.
Preferably, in the step (2), the degumming temperature is 50-60 ℃.
Preferably, in the step (3), the dipping time is 3-5min, the drying temperature is 20-30 ℃, and the drying time is 15-25 min; the curing temperature is 165-175 ℃, and the curing time is 2-4 min.
Preferably, in step (3), the number of dipping, drying and curing is 1 to 10.
The silk fabric with different cerium oxide nanoparticle contents can be obtained by repeating the steps as required.
Preferably, in the step (4), the mass ratio of the PDMS to the isopropanol is 1: 60-70.
Preferably, in the step (4), the drying temperature is 15-25 ℃, and the drying time is 15-25 min; the curing temperature is 55-65 ℃, and the curing time is 170-190 min.
Compared with the prior art, the invention has the following technical effects:
(1) the invention makes CeO by dipping method2The nano-particles are attached to the surface of the silk fabric, so that the silk fabric is endowed with excellent ultraviolet resistance. CeO (CeO)2Compared with zinc oxide and titanium dioxide nanoparticles, the nano-composite material has a relatively small band gap and stronger ultraviolet resistance.
(2) The invention aims to solve the problem of CeO adhesion2Nano-particle silk fabric with poor hand feeling and CeO2The problem that nano particles fall off easily is solved, and a transparent PMDS film with high flexibility and elasticity is further arranged on the surface of the silk fabric, so that the silk fabric can not only haveEffectively improve the hand feeling of silk fabrics and prevent CeO2The nanoparticles fall off. In addition, the PDMS film has transparency, and does not affect CeO2The ultraviolet resistance of the nano particles.
