Description

Diabetic foot health-care socks containing silver fibers

Technical Field

The invention belongs to the technical field of textiles, and particularly relates to a pair of diabetic foot health-care socks containing silver fibers.

Background

With the development of science and technology and the progress of textile industry, the types of textiles are continuously increased, the requirements of people on the textiles are higher and higher, and besides appearance quality, colors and styles, products with specific functions are favored by people more and more.

For the diabetic, the feet of the diabetic are easy to sweat, the diabetic can fester and is not easy to recover once being infected by bacteria, and clinically, the diabetic is affected by hyperglycemia for a long time, so that blood vessels of the lower limbs are hardened, the blood vessel walls are thickened, the blood vessels are easy to form thrombus and are integrated into plaques, and the blood vessels of the lower limbs are occluded. It is therefore desirable to provide a diabetic foot health sock to improve the foot environment of a patient.

In the process of blending the silver fiber with other fabric fibers, the silver fiber is usually arranged among other fabric fibers at intervals, for example, a knitted fabric containing the silver fiber and a manufacturing process thereof disclosed in Chinese patent CN 102505303A; and a plurality of single-stranded all cotton yarns and the silver fibers subjected to oxidation treatment are arranged at intervals, the distance between every two adjacent silver fibers is 2-10 mm, and the pattern of the whole fabric is in a stripe shape.

After the existing silver fiber textile fabric is washed for many times, the sterilization and radiation protection effects are obviously reduced. The reason for this is probably that silver is peeled off from the surface of the fiber by water impact and mutual rubbing of the fabric during washing, and the rubbing of the fabric against an object in life causes the peeling of silver.

In view of the above, the present invention is particularly proposed.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It was found that silver plus a weak current can cause the fibroblasts to differentiate poorly. Fibroblasts are a common cell type that, when transformed into other cell types, significantly promote tissue repair and regeneration. Recent studies have also demonstrated that elemental silver accelerates the rate of epithelial regeneration in locally non-infected acute wounds. It is thus seen that silver, in addition to its antimicrobial properties, also has wound healing promoting properties.

It has also been found that silver can reduce the activity of metalloproteinases. Metalloproteinases (MMPs) are a class of proteases that are present in wounds and can break down necrotic tissue, normally maintaining an equilibrium state between MMPs and natural inhibitors and growth factors. MMP structure contains sulfhydryl, and activation requires participation of zinc ions. When burns or chronic wounds occur, MMP activity is enhanced, and high MMP activity can destroy growth factors and new tissues and prevent the wounds from healing. While silver can bind to sulfhydryl groups in the MMP structure or reduce excessive MMP activity by reducing zinc ions at the wound surface. It has also been reported that silver increases the amount of calcium on the wound surface, which accelerates epithelial regeneration.

The fineness of the cotton fiber is preferably smaller than that of the silver fiber, so that the silver fiber is not easily blocked by the cotton fiber after being blended with the cotton, and the separation of silver ions is facilitated. The fineness of the silver fiber is 60 to 65 deniers, preferably 65 deniers, in terms of fiber fineness. The inventors have surprisingly found that when the fineness of the silver fiber is in the above range, the retention of the antibacterial effect of the textile fabric after multiple water washes can be significantly improved, which the inventors consider is probably because the silver fiber can maintain good tightness with adjacent fibers during carding, roving and the like after the proper fineness range is adopted. The cotton fibers may be of a smaller denier than the silver fibers, for example, between 20 and 40 denier.

The invention provides a pair of diabetes foot health care socks containing silver fibers, which comprises a sock foot and a sock barrel which are connected, wherein the sock foot is formed by sewing a plurality of layers of composite materials, the plurality of layers of composite materials comprise a pure cotton textile layer, a spandex elastic yarn layer and a silver fiber braided layer which are sequentially stacked, and a contraction opening is formed in the top end of the sock barrel. The multilayer composite material comprises 4-6% of silver fiber, 9-11% of spandex and 84-86% of cotton by mass percent.

In some embodiments, it is preferable that the multilayer composite material comprises 3% silver fiber, 48.5% cotton and 48.5% viscose fiber by mass percentage.

The fineness of the silver fibers is 60-65 deniers, the base fibers of the silver fibers are chinlon, the fineness of the cotton is smaller than that of the silver fibers, and the silver fibers are provided with silver metal coatings with the silver content of more than 99.9%.

The inner sides of the front sole area and the heel area of the sock foot are provided with convex buffer pads. The sock leg contraction opening is provided with a telescopic fiber bundle, and the telescopic fiber bundle extends around the axis of the sock leg in a coiling mode. The telescopic fiber bundle starts from the bottom of the sock leg and extends to the top of the sock leg. Through setting up the cushion pad, can protect the fragile foot of diabetes mellitus patient, prevent the bruise, the welt is the top of leg of a stocking not set up the rid cuff of tightening up, but replaces through flexible tow, when avoiding the welt tension to lead to the thrombus, still plays the supporting role to the leg of a stocking, will disperse the power of cramping to patient's ankle and shank.

Silver fiber textile socks were made according to the following examples 1-3, comparative examples 1-3. The fineness of the cotton yarn and spandex in the table are both 30 deniers. The average length of the silver fibers is 2-4 cm.

Specific examples are as follows:

table 1:

detection of antibacterial Effect

The socks obtained in examples 1 and 2 and comparative examples 1 to 3 were subjected to an antibacterial test. The specific test method is to detect the escherichia coli inhibition rate, the staphylococcus aureus inhibition rate and the candida albicans inhibition rate after washing for 240 times. The concrete results are as follows

Table 2:

from the results in Table 2, it is understood that the antibacterial effect is the best when the fineness of the silver fiber is 65 deniers, and at 60 deniers, the bacteriostatic rate of Candida albicans is slightly lower, and the two other indexes can be maintained at 90% or more. And the antibacterial effect of the silver fibers with other deniers is not ideal after 240 times of washing.

The foregoing is merely exemplary and illustrative of the present invention and various modifications, additions and substitutions may be made by those skilled in the art to the specific embodiments described without departing from the scope of the present invention as defined in the accompanying claims.
