Problems solved by technology

It is also difficult to achieve the desired effect with chemical antibacterial finishing. This is because the existing antibacterial finishing methods for silk fabrics are mainly used for silk clothing, and its use environment is different from decorative silk fabrics or silk craft fabrics. Therefore, it is easy to accumulate dust, which makes it easier for various microorganisms to attach and grow and reproduce, and is more affected by light, and the use environment is harsher and harsher. Generally, antibacterial finishing methods for clothing materials are not effective.

Embodiment 1

[0008] Lay the thickened silk brocade with a weight of 200 grams per square meter on the platen, and use a polyacrylate film-forming agent with a viscosity of 12000cp and a solid content of 25% (containing 3% isothiazolinone antibacterial agent) , scrape it onto the silk fabric with a rubber scraper by hand. The steps of scraping coating are as follows: first scrape coating on the reverse side of the fabric, then turn it over and scrape coating on the front side. The requirements for scraping coating are: the scraper is evenly applied, and the coating should be as thin as possible, but there should be no coating holes or missing coatings. When double-sided scraping, the front and back coatings should form a continuous film. Before scraping and coating, the silk fabric needs to be pretreated and dried in an oven. The drying temperature is 70°C and the drying time is 0.5 hours. After the coating is applied, the fabric is put into an oven for thermal curing at a temperature of ...

Embodiment 2

[0011] The real silk fabric of 148 gram weights per square meter is tiled on the platen, adopts viscosity to be 8000cp, the polyacrylate film-forming agent (wherein containing isothiazolinones antibacterial agent 4%) that solid content is 30%, with It is applied by hand with a rubber roller to silk fabrics. The steps of rolling coating are: roll coating on the reverse side of the fabric first, then turn it over and roll coating on its front side. The requirements for roller coating are: the pressure of the roller on the surface of the fabric should be uniform, and the coating should be as thin as possible, but there should be no coating holes or missing coatings. When rolling coating on the front and back sides, the front and back coatings should form a continuous film. Before roll coating, the silk fabric needs to be pretreated and dried in an oven at a drying temperature of 70°C for 0.5 hours. After the coating is coated, the fabric is placed under ventilated room temperat...

Abstract

The invention discloses a method for protecting silk fabrics, which comprises the following steps of: coating a polymer emulsion film-forming agent containing a certain amount of antimicrobial on the two sides of a fabric; and then carrying out heat-curing or room temperature air-drying to form a soft and transparent continuous closing film on the surface of the fabric, wherein the thickness of the film is 0.1 to 0.5mm, the viscosity of the selected film-forming agent is 50 to 20,000cp, the solid content of the film-forming agent is 20 to 55 percent, and the antimicrobial content in the film-forming agent emulsion is 1 to 5 weight percent. The coating method is a manual coating method by a rubber scraper blade or a manual roller coating method by a rubber roll; and the surface continuous film has certain closing function of isolating air and functions of resisting mould and damp, and can prolong the service life and hold time of a textile. The method is applicable to various silk-containing textiles and silk decorative fabrics.

Description

technical field [0001] The present invention relates to a fabric protection method for silk-containing materials. The method can effectively block the air, cut off the nutrient source of microorganisms, and produce an active anti-mildew and anti-corrosion effect, which can prolong the service life and storage time of the fabric. technical background [0002] Silk is a kind of natural protein fiber, which itself is a source of nutrition for various microorganisms and moths. It is easy to absorb moisture in a certain humidity air, and it is easy to mold and moth-eaten under a suitable temperature (25-40°C). The microorganisms that attack silk fabrics are mainly putrefactive bacteria and molds. These microorganisms are mixed in the air daily, and their colonies grow and multiply on the surface of the fabric, making the fibers brittle and decomposed, the material changes color, and the strength decreases. The reproduction of bacterial colonies will cause mold spots on the surfa...
