Abstract
Description
Technical Field
[0001] This utility model relates to the field of knitted fabric technology, and more specifically to an adaptive knitted fabric structure with automatically adjustable tightness. Background Technology
[0002] Knitted fabric is a type of fabric formed by bending yarns into loops and interlocking them using knitting needles. It is divided into warp-knitted and weft-knitted fabrics. Knitted fabrics are soft, moisture-wicking, breathable, and warm, and generally possess excellent elasticity and extensibility. Compared to woven fabrics, they offer higher production volume and are suitable for small-batch production. Knitted fabrics have a wide range of applications. Due to their good elasticity, moisture absorption, and warmth retention, they are most commonly used in clothing fabrics. They are also used in other special applications, such as padding. The most common example is plaster cast padding. When people have fractures or bone injuries, plaster casts are needed, and padding is worn over them for fixation. The most important function of padding is to adapt to changes in tightness; it should wrap around the plaster cast when applied and automatically shrink back when removed. Clearly, existing knitted fabric structures lack sufficient elasticity, have a short lifespan, and easily become loose, making them unsuitable for use as padding. To address this issue, the inventors propose an adaptive knitted fabric structure that can automatically adjust the tightness of the fabric. Elastic fiber yarns are added during the knitting process to enhance the elasticity of the fabric structure, enabling it to adapt to different tightness levels. This structure is not only highly practical but also has a long service life.
[0003] To increase the elasticity of knitted fabrics, prevent them from being stretched and deformed by external forces, and enable them to automatically recover their original shape, Chinese patent (authorization announcement number: CN222891772U) discloses a composite knitted fabric. This utility model includes a base layer and a surface layer. The base layer has several first air vents, and the surface layer has several second air vents communicating with the first air vents. Both the first and second air vents have several circumferentially oriented grooves along their edges. Several elastic pads are placed between the base layer and the surface layer, bonded between the first and second air vents. Each elastic pad has a through hole at its center communicating with both the first and second air vents. This utility model allows the first and second air vents to actively deform under stress and automatically recover their original shape, thus preventing complete stretching and deformation by external forces and giving the knitted fabric good shape retention.
[0004] The solution still has some shortcomings in application. Since knitted fabric is usually designed as a single layer when used as padding, in order to improve breathability, avoid overheating and skin discomfort, and also improve the service life of the knitted fabric and prevent it from tearing or delaminating, the structure of the knitted fabric needs to be improved so that it has good elasticity, can automatically adjust the tightness, has good breathability, and is easy to put on and take off. Utility Model Content
[0005] This utility model discloses an adaptive knitted fabric structure that can automatically adjust the tightness, the main purpose of which is to overcome the above-mentioned deficiencies and shortcomings of the existing technology.
[0006] The technical solution adopted in this utility model is as follows:
[0007] An adaptive knitted fabric structure with automatically adjustable tightness includes a knitted fabric body. The knitted fabric body has multiple weft knitting units connected in sequence. Each weft knitting unit includes several knitting threads arranged vertically. The knitting threads are knitted using a rib structure to form several rows of loops. High-elasticity yarns are threaded between the rows of loops. The high-elasticity yarns form an open arc structure on the loops. The high-elasticity yarns float on the remaining loops. A tubular elastic bandage is sewn into the middle section of the knitted fabric body.
[0008] Furthermore, the high-elasticity yarn is made of a blend of spandex and silk fibers.
[0009] Furthermore, the coils are provided with a through gap, and there are several ventilation holes between the through gaps.
[0010] Furthermore, the braided yarn is made of filament yarn made of elastic fibers.
[0011] Furthermore, the high-elasticity yarns are arranged in parallel vertically.
[0012] As can be seen from the above description of this utility model, compared with the prior art, the advantages of this utility model are as follows:
[0013] This invention firstly involves sewing a tubular elastic bandage into the middle section of the knitted fabric body. This tubular elastic bandage prevents the knitted fabric body from being completely stretched and deformed by external force. Next, the weft knitting unit of the knitted fabric body uses a rib knitting structure, and the knitting yarn is made of long filament yarn made of elastic fibers, giving the knitted fabric body good elasticity and adjustable tightness. At the same time, the loops on the knitted fabric body have through seams with ventilation holes, making the knitted fabric body not only elastic but also breathable. Finally, high-elasticity yarn is threaded between the loops. The high-elasticity yarn is made of a blend of spandex and silk fibers, which has a high elastic elongation and rapid recovery ability. In addition, the high-elasticity yarn floats and stays in some loops, allowing for stretching and contraction, further giving the knitted fabric body an adaptive tightness effect. This invention has a novel structure and ingenious design, can actively stretch under force and automatically recover, making it suitable for widespread use in medical pads.
