Compression stocking, compression stocking weaving process and seamless hosiery machine

Abstract

A compression stocking, a weaving process of the compression stocking, and a seamless hosiery machine applied in the process. A stocking body (2) of the compression stocking comprises a stable region (11), compression gradually-changing regions (12, 13, 14), and a compression difference region. The stable region (11) is connected to a stocking foot (3). A length parameter (LA) and a middle girth parameter (B) of the stable region (11) are set separately according to a length parameter (LA) of an ankle and a girth parameter (cB) of a thinnest part of the ankle. The interface compression in the stable region (11) is kept consistent. The compression gradually-changing regions (12, 13, 14) are located between the stable region (11) and a welt (1), the stable region (11), the compression gradually changing regions (12, 13, 14) and the welt (1) are sequentially connected from bottom to top. The interface compression in each of the compression gradually-changing regions (12, 13, 14) gradually decreases from bottom to top, the interface compression of the joint of the neighboring compression gradually-changing regions (12, 13, 14) is kept successive, and each of the compression gradually-changing regions (12, 13, 14) has a preset compression gradually-decreasing gradient. The compression difference region is located in a local region surrounded by the stable region (11) and / or the compression gradually-changing regions (12, 13, 14). The interface compression in the compression difference region may be distributed in a gradient manner or in an even manner. The compression stocking can meet requirements for the specific compression magnitude and the distribution of different parts of a lower limb.

Description

technical field [0001] The invention relates to the field of knitwear manufacturing, in particular to a compression stocking, a weaving process for the compression stocking, and a seamless circular stocking machine. Background technique [0002] Compression stockings, that is, medical compression stockings, are often called elastic stockings in China. They are products that can prevent and treat venous diseases of the lower extremities and promote the return of venous blood to the heart. Compression stockings establish the highest support pressure at the ankle, and the pressure gradually decreases along the leg, for example, the calf is reduced to 50%-80% of the maximum pressure value, and the thigh is reduced to 20%-60% of the maximum pressure value . This decreasing change of pressure can make the venous blood of the lower extremities return, and effectively relieve or improve the pressure on the veins and venous valves of the lower extremities. [0003] Wherein, the pre...

AI Technical Summary

Problems solved by technology

At present, during the use of compression stockings, the weft-knitted fabric used to provide interfacial pressure will produce structural slippage due to multi-directional stretching, thereby affecting the degree of tightness, resulting in excessive or insufficient pressure in compression stockings to varying degrees And problems such as irregular pressure distribution directly affect the wearing effect of compression stockings

Moreover, in the actual use of compression stockings, the pressure of the same circumference of the leg is different in different directions, which is related to the structure and surface curvature of the cross-section of the lower limbs of the human body, specifically, the pressure along the great saphenous vein The front, outside and back of the leg are smaller compared to other legs on the same circumference, which to some extent causes insufficient effective pressure dose
