Technical Field

[0001] The invention relates to the technical field of fabrics, and in particular to a post-processing method for long-term preservation of silk brocade. Background Art

[0002] Silk brocade fabric Silk brocade mainly uses high-quality mulberry silk as raw material, and sometimes other fibers such as gold and silver threads are added to increase visual effects and texture. Brocade fabric is famous for its unique luster, rich colors and exquisite patterns. It is a high-end textile and has become a carrier of cultural value.

[0003] However, due to the material characteristics of conventional silk brocade, silk brocade fabric is sensitive to light, especially strong sunlight, which can cause the fabric to become brittle, fade, yellow, and dull.

[0004] In order to extend the service life of silk brocade fabrics and maintain their beauty, this scheme introduces natural plant extracts, such as wax gourd peel extract, which has many positive effects on fabrics, including anti-oxidation and antibacterial effects. These properties make wax gourd peel extract have potential application value in the field of silk fabric treatment. Summary of the invention

[0009] Step 2: Pre-treatment of brocade fabrics:

[0010] Plasma treatment of brocade fabrics;

[0011] Step 3: Finishing of brocade fabric;

[0012] The brocade fabric is put into the finishing liquid for double dipping and double rolling, and then hot drying is performed to obtain the antibacterial and anti-aging brocade fabric.

[0013] Furthermore, the amounts of wax gourd peel extract, hydrogen peroxide, ultraviolet absorber, ultraviolet finishing agent and deionized water are as follows by mass percentage: wax gourd peel extract 8-12%, hydrogen peroxide 1-3%, ultraviolet absorber 5-10%, ultraviolet finishing agent 5-10% and deionized water 70-80%.

[0014] Furthermore, the preparation process of the wax gourd peel extract is:

[0015] After crushing the melon peel, add an appropriate amount of distilled water, and usually use ultrasonic extraction, ultrasonic 4 times, each time for 1 hour;

[0016] After the extraction is completed, the residue is removed by filtration, and the extract is evaporated, concentrated and evaporated to obtain the wax gourd peel extract.

[0017] Furthermore, the ultraviolet absorber is one of benzophenone compounds, salicylate compounds, and benzoic acid compounds;

[0018] Furthermore, the ultraviolet finishing agent is one of nano titanium dioxide, litsea cubeba residue extract, citric acid, and polydimethylsiloxane.

[0019] Furthermore, the pH value of the finishing liquid in step 1 is neutral to slightly acidic.

[0020] The beneficial effects achieved by the present invention using the above structure are as follows:

[0021] Winter melon peel extract is rich in polyphenols and flavonoids, which have significant antioxidant activity. In fabric processing, winter melon peel extract can slow down the aging and yellowing of fabrics caused by factors such as light and oxygen, thereby extending the service life of the fabrics.

[0022] Winter melon peel extract has an inhibitory effect on a variety of bacteria and fungi, especially its ethyl acetate extract shows the best antibacterial effect. Applying this extract to fabrics can give the fabrics good antibacterial properties, reduce bacterial growth, and keep the fabrics clean and hygienic.

[0023] Winter melon peel extract is synergistically combined with hydrogen peroxide, UV absorber and UV finishing agent to further optimize the fabric's anti-UV and antibacterial properties, extend the service life of the silk brocade fabric, and achieve the technical effect of maintaining the silk brocade fabric's beauty for a long time.
