The antibacterial textile is a new fabric widely applied in recent years, and has certain antibacterial effect, is beneficial to human health, is highly accepted by consumers and has potential market prospect. The feet are the second hearts of people, the requirements on the sock fabric are extremely high, and especially the feet are easy to breed and propagate bacteria due to sweat during sports, so that the influence on the health of human bodies is the most important. At present, the functions of the antibacterial socks are mainly realized by finishing socks after weaving by using antibacterial finishing agents such as silver ions and copper ions, or by blending fibers with natural antibacterial property such as hemp fibers and chitosan fibers into yarns and then weaving the yarns into the antibacterial socks; the former has the problems of harming human health, increasing pollution discharge and energy consumption due to the heavy metal ions such as silver and the like in the soft finishing agent, and the latter is difficult to meet the daily large-scale demand due to limited resources and higher cost.
The alginate fiber has natural antibacterial and bacteriostatic properties, is the best raw material for manufacturing antibacterial textiles, and becomes a research hotspot in recent years. For example, CN202010380572.2 discloses antibacterial skin-beautifying socks containing alginate fibers, wherein the sock main body is internally composed of an alginate fiber covering layer, a cotton cloth layer, a bamboo fiber layer and a spandex surface layer, and the alginate fiber covering layer internally comprises an antibacterial masterbatch layer, an alginate carbon fiber layer and an alginate mineral layer. The bamboo fiber has natural antibacterial, bacteriostatic, mite-removing, deodorant and ultraviolet-resistant functions, and the seaweed carbon fiber fabric has double effects of heat preservation and health care, so that the seaweed carbon fiber fabric can generate thermal reaction due to the friction of human molecules after being worn for a long time, promotes the blood circulation of a body, and has the effects of heat storage and heat preservation. CN201920206461.2 discloses socks with antibiotic deodorization function, through setting up socks body, the cotton layer of combing, antibiotic layer and alginate fiber layer, the cotton layer of combing has good sweat-absorbing performance and thermal insulation performance, has avoided the sweat of foot more to breed the bacterium and has reduced the comfort level of socks body, and antibiotic layer can resist and reduce the bacterium and breed at the foot in addition, has strengthened the protection of socks body to the foot. CN205794825U discloses a breathable and antibacterial sock, the sock body is provided with a dustproof layer, an antibacterial layer and a breathable layer in sequence from outside to inside, the antibacterial layer is formed by blending alginate fibers, nano-silver fibers and chitin fibers, and the better breathable, dustproof and antibacterial effects of the sock are achieved.
However, the current alginate fiber antibacterial socks have the defects of single structural function, non-bright color, short service life, easy hydrolysis, processing damage to alginate fibers and high cost, so that the research and development of alginate fiber health-care socks which have good antibacterial effect, high safety performance, water washing resistance and easy processing becomes the current research direction.

The color fastness to light is determined according to GB/T8430-1998; the determination of the color fastness to rubbing is carried out according to GB/T3920-; the color fastness to acid perspiration and the color fastness to alkali perspiration are determined according to GB/T3922-2013.
2. Testing air permeability, wear resistance and burst strength
The air permeability is determined according to GB/T5453, and YG461-B type fabric medium-low pressure air permeability instrument is selected, and the pressure drop is selected to be 100 Pa.
The wear resistance standard is according to FZ/T01121-.
The bursting was tested according to GB/T8878 with HD026 electronic fabric dynamometer, bursting speed was set at 100mm/min, the main test parts were heel and toe, 5 times of tests were carried out respectively, and the respective average values were calculated.
