Problems solved by technology

The active ingredients of the functional components (tea pigments or tea polyphenols or catechins) used in this patent are basically water-soluble, basically without protection or simple adsorption protection, and are not suitable for wet processing of cellulose fibers. Spinning, there is a serious problem of loss in the subsequent spinning process, which affects the functionality of the fiber
[0010] Chinese patent 200810025069.4 (a tea cellulose fiber production process) and Chinese patent 201410282478.8 (a green tea fiber fabric) are two patented technologies that pre-process tea raw materials Pulp, and then go through the cellulose fiber production process to prepare related fibers. The production process is long. Most of the functional components in tea are damaged by strong acid and alkali, which affects the functionality of fibers or fabrics.
[0016] Collagen is a biological polymer that plays a role in combining tissues in animal cells. It is the most abundant protein in the human body and is rich in the Glycine, proline, hydroxyproline and other amino acids can improve immune function, activate cell function, activate muscles and bones, prevent skin aging, remove wrinkles, and have good skin care and health care functions, but alone
[0017] Collagen added to the spinning dope, there is also the problem of easy loss

Abstract

The invention provides a preparation method of plant antibacterial, antiviral, skin-care and health-care cellulose fibers. The preparation method is characterized by comprising the steps of preparingof a blended spinning stock solution, spinning and aftertreatment. Tea polyphenol and zinc elements are used for endowing the fibers with excellent antibacterial and antiviral functions, meanwhile, operation is assisted by the skin-care and health-care functions of collagen, so that the prepared functional cellulose fibers have antibacterial, antiviral, skin-care and health-care functions, the inhibition rate on staphylococcus aureus is larger than or equal to 92.6%, the inhibition rate on escherichia coli is larger than or equal to 93.8%, the inhibition rate on candida albicans is larger thanor equal to 90.3%, the inactivation rate on influenza A viruses is larger than or equal to 85.6%, the inactivation rate on influenza B viruses is larger than or equal to 86.2%, and the inactivation rate on herpes viruses is larger than or equal to 82.8%. The fibers contain multiple kinds of amino acid trace elements, and therefore good skin-care and health-care functions are achieved.

Description

technical field [0001] The invention belongs to the technical field of functional regenerated cellulose fibers, and specifically relates to a kind of tea polyphenol with antibacterial and antiviral functions, zinc element and collagen for skin care and health care as raw materials, and is used for adding before spinning and post-processing. , thereby preparing plant-based antibacterial, antiviral, skin care and health care cellulose fibers and a preparation method thereof. Background technique [0002] In recent years, the textile industry has launched many fibers and textiles with health care and medical functions that are beneficial to human health and environmental protection, and have achieved gratifying results, with huge market potential. Because cellulose fiber products have the advantages of moisture absorption, good air permeability, comfortable wearing, and natural degradation, they have made great progress in health care and medical functions in recent years, amon...
