Embodiment 1

[0035] The weaving process and antibacterial test results of a woven plain wool fabric with polymer optical fibers are as follows:

[0036] (1) The photosensitizer is fixed on the wool yarn by means of dyeing agent, which is woven into the fabric as warp yarn. The concentration of methylene blue dye is 0.5-3% owf, and the temperature is 60℃-140℃.

[0037] (2) The fabric weft yarn is a plastic optical fiber (with a diameter of 0.25 mm or 0.50 mm) with polymethyl methacrylate (PMMA) as the core and fluororesin as the sheath, and ordinary wool yarn or all plastic optical fibers. If there are two kinds of yarns, the interweaving relationship between them is plastic optical fiber: ordinary wool yarn=10:1~1:10.

[0038] (3) Finally, refer to GB / T20944.1~2007 "Evaluation of antibacterial properties of textile materials: Agar plate diffusion method" or GB / T20944.2~2007 "Evaluation of antibacterial properties of textile materials: Absorption method" or GB / T20944. 3~2008 "Evaluation of Antib...

Embodiment 2

[0040] The weaving process and antibacterial test results of a woven plain wool fabric with polymer optical fibers are as follows:

[0041] (1) The photosensitizer is fixed on the wool yarn by means of dyeing agent, which is woven into the fabric as warp yarn. Among them, the methylene blue dye concentration is 0.5-3% owf, the dyeing solution has a pH of 4-5, and the temperature is 80°C to 135°C.

[0042] (2) The fabric weft yarn is a plastic optical fiber (with a diameter of 0.25mm or 0.50mm) with polystyrene (PS) as the core and fluororesin as the sheath, and ordinary wool yarn or all plastic optical fibers. If there are two kinds of yarns, the interweaving relationship between them is plastic optical fiber: ordinary wool yarn=10:1~1:10.

[0043] (3) Finally, refer to GB / T20944.1~2007 "Evaluation of antibacterial properties of textile materials: Agar plate diffusion method" or GB / T20944.2~2007 "Evaluation of antibacterial properties of textile materials: Absorption method" or GB / T...

Embodiment 3

[0045] The weaving process and antibacterial test results of a woven plain wool fabric with polymer optical fibers are as follows:

[0046] (1) The photosensitizer is fixed on the wool yarn by means of dyeing agent, which is woven into the fabric as warp yarn. The methylene blue dye concentration is 0.5-3% owf, the dyeing solution has a pH of 4-5, and the temperature is 70°C to 135°C.

[0047] (2) The fabric weft yarn is a plastic optical fiber (with a diameter of 0.25mm or 0.50mm) with polycarbonate (PC) as the core and fluororesin as the sheath, and ordinary wool yarn or all plastic optical fibers. If there are two kinds of yarns, the interweaving relationship between the two is plastic optical fiber: ordinary wool yarn=1:10~10:1.

[0048] (3) Finally, refer to GB / T20944.1~2007 "Evaluation of antibacterial properties of textile materials: Agar plate diffusion method" or GB / T20944.2~2007 "Evaluation of antibacterial properties of textile materials: Absorption method" or GB / T20944. ...

Abstract

The invention discloses fabric and a preparation method thereof. The fabric comprises optical fibers and a photosensitizer, wherein the optical fibers and the photosensitizer are consolidated in the fabric and are distributed in the fabric in a staggered manner. According to the fabric and the preparation method thereof, the problem of poor antibacterial property of common fabric under the condition of a single weak light source can be solved; compared with pure photodynamic fabric, the fabric has the advantages that by addition of the polymer optical fibers, the effective utilization rate ofthe photosensitizer is increased, and even if the fabric is in a folded state, and the antibacterial effect is better than that of fabric without the polymer optical fibers only by providing the fabric with a weak light source; compared with combination of common indoor textiles and an air purifier, the fabric has the advantages that space is greatly saved, the antibacterial effect is better, andthe broad-spectrum antibacterial property is stronger.

Description

Technical field [0001] The invention belongs to the technical field of fabrics, and specifically relates to a fabric and a preparation method thereof. Background technique [0002] Photosensitizer, also known as sensitizer, sensitizer, and photocrosslinking agent. In a photochemical reaction, a substance that transfers light energy to some reactants that are not sensitive to visible light to improve or expand its photosensitive properties. [0003] In photochemical reactions, there is a class of molecules that only absorb photons and transfer energy to those molecules that cannot absorb photons to promote chemical reactions, but they do not participate in chemical reactions and return to their original state. Such molecules are called Photosensitizer. The photochemical reaction initiated by the photosensitizer is called the photosensitive reaction. Generally, people call the photosensitivity reaction accompanied by biological effects with the participation of aerobic molecules a...
