preparation example Construction

[0037] A preparation method of a natural long-acting antibacterial functional polyester blanket, comprising:

[0038] Step 1. Prepare antibacterial functional solution:

[0039] Dissolve 1-3g chitosan in 100 mL of sterilized silk fibroin protein solution of 2%-15%, adjust the pH to 3-6, and stir and mix well with a magnetic stirrer to obtain an antibacterial solution containing chitosan , and then add a polyethylene glycol (10000D) solution with an equal volume of 50% mass fraction to the mixture, leave the resulting mixture for 8-16 hours, and then perform centrifugation and washing to obtain silk fibroin / chitosan microspheres. solution.

[0040] Step 2, low temperature plasma pretreatment:

[0041]Soak the polyester raschel blanket in anhydrous ethanol solution, and fully wash it in an ultrasonic cleaner for 30-60 min, rinse it with deionized water and dry it in an oven at 60°C, and spread the dried polyester blanket on the The steel wire mesh is placed in the plasma trea...

Abstract

The invention discloses a preparation method of a polyester raschel blanket with a natural long-acting antibacterial function. A multifunctional solution is obtained from chitosan carried by silk fibroin and used for modifying a polyester raschel blanket. The modified blanket has Escherichia coli resistance of 50%-90% and antistatic decay time of 7-28 s. The problems of low air and water vapor permeability, poor handfeel and the like of the polyester raschel blanket modified with the traditional method are solved, the polyester raschel blanket is endowed with lasting natural antibacterial andantistatic functions and other functions, and additional value and market competitiveness of the polyester raschel blanket are increased.

Description

technical field [0001] The invention belongs to the field of functional textiles, and in particular relates to a preparation method of a natural long-acting antibacterial functional polyester blanket. Background technique [0002] In recent years, with the improvement of people's living standards, people pay more and more attention to the functionality of textiles, especially the antibacterial, antistatic, and comfort properties of textiles. Because of its low price, soft touch, warmth and breathability, and pleasing color patterns, raschel blankets are gradually loved by people and are often used in bedding and decorative items. Raschel blankets are mainly made of acrylic fibers and polyester as the main raw materials. Due to the high cost of acrylic fibers, the overall performance is not much different from that of polyester blankets, so they are gradually replaced by polyester. However, the macromolecules of polyester fiber cannot ionize and transfer electrons. In additi...
