Description

Technical Field

[0001] The invention relates to the technical field of fiber fabric preparation, and in particular to a green and environment-friendly antibacterial and anti-mite functional fiber fabric. Background Art

[0002] With the improvement of people's living standards, the functional demand for textiles is increasing, especially fiber fabrics with antibacterial and anti-mite functions, which have gradually become the focus of consumers' attention. At present, there are some fiber fabrics with antibacterial and anti-mite functions on the market, but they generally have several problems. First, these fabrics are mostly treated with chemical additives for antibacterial treatment. Although they can temporarily achieve antibacterial effects, due to the volatility and migration of chemical components, their antibacterial effects are often not lasting. Secondly, many antibacterial fabrics use a large amount of chemicals in the production process, which causes certain environmental pollution and potential harm to human health. In addition, these fabrics have a rough feel and poor comfort, which makes it difficult to meet consumers' requirements for high-quality fabrics.

[0003] Therefore, there is an urgent need for a green and environmentally friendly antibacterial and anti-mite functional fiber fabric, which should solve the problems of the existing technology, such as the short-lasting antibacterial effect, the environmental pollution and health problems that may be caused by chemical additives, and the poor hand feel of the fabric. Summary of the invention

[0004] Based on the above purpose, the present invention provides a green and environmentally friendly antibacterial and anti-mite functional fiber fabric.

[0005] A green and environmentally friendly antibacterial and anti-mite functional fiber fabric comprises bamboo charcoal fiber, silver ion antibacterial fiber, aloe fiber, chitosan fiber, lotus fiber, polylactic acid fiber and natural cotton fiber; the specific preparation of the functional fiber fabric comprises the following steps:

[0006] S1: drying bamboo charcoal fiber, silver ion antibacterial fiber, aloe fiber, chitosan fiber, lotus fiber, polylactic acid fiber and natural cotton fiber to remove moisture;

[0014] Optionally, the drying treatment temperature of each fiber in S1 is 60° C.-80° C., and the treatment time is 2-4 hours, ensuring that the moisture content of each fiber does not exceed 5%.

[0015] Optionally, the mixing time of the various types of fibers in S2 is 20-30 minutes, and the rotation speed of the mixing device is 200-300 rpm.

[0020] Optionally, a neutral detergent is used for washing in S7, the washing temperature is 30-40 degrees Celsius, and the washing time is 10-15 minutes.

[0021] Optionally, the softening treatment in S7 uses a 10%-20% cationic softener solution, and the treatment time is 5-10 minutes.

[0022] Beneficial effects of the present invention:

[0023] The present invention achieves a lasting antibacterial and anti-mite effect by adopting ingredients of natural origin such as bamboo charcoal fiber, silver ion antibacterial fiber, etc., combined with a unique preparation process. Compared with traditional antibacterial fabrics, the materials used in the present invention are natural and safe, and do not need to rely on potentially harmful chemical additives, thereby significantly reducing the impact on the environment and potential risks to the human body.
