example 1

[0023] The fabric in this embodiment is woven by knitting double-face weft knitting technology. The low modulus deformation range is set at 70%.

[0024] The fabric structure is a 3-way weaving cycle, and its weaving diagram is as follows Figure 4 shown. First pass: Low modulus yarn is knit in a loop on the upper cylinder needles and in a tuck loop on the lower cylinder knitting needles. Second pass: High modulus yarns are knitted in loops only on the lower cylinder needles. Third way: Low modulus yarn is knitted in loops on the upper dial needles only. The relationship between the external force and the deformation required for its deformation The tension / load curve is as follows Figure 7 shown. From Figure 7 We can get the low modulus area of ​​the fabric in the 0%-50% stretch area, the 50%-70% stretch area is the structural conversion area, and the stretch area above 70% is the high modulus area. The tensile force required for tensile deformation increases very sl...

[0026] In order to further demonstrate that the deformation range of the low modulus area can be controlled, the same high and low modulus materials as in Example 1 are used, and the fabric in this example is woven by knitting double-sided weft knitting technology to form Example 2.

[0027] The fabric structure is a 7-way weaving cycle, and its weaving diagram is as follows Figure five . First pass: Low modulus yarn is knit in a loop on the upper cylinder needles and in a tuck loop on the lower cylinder knitting needles. Second pass: High modulus yarns are knitted in loops only on the lower cylinder needles. Third way: Low modulus yarn is knitted in loops on the upper dial needles only. The fourth way: the high modulus yarn weaving method is the same as the second way. The fifth way: the low modulus yarn is knit in a circle on the upper needle disc, and in a tuck on the lower cylinder knitting needle. Sixth way: High modulus yarns are knitted in loops only on the lower c...

[0030] Continue to design a larger range of low modulus variation, using the same high and low modulus materials as in Example 1, the fabric in this embodiment is woven by knitting double-sided weft knitting technology

[0031] The fabric structure is a 4-way weaving cycle, and its weaving diagram is as follows image 3 . First pass: Low modulus yarn is knit in a loop on the upper cylinder needles and in a tuck loop on the lower cylinder knitting needles. Second pass: High modulus yarns are knitted in loops only on the lower cylinder needles. Third way: Low modulus yarn is knitted in loops on the upper dial needles only. The fourth way: the high modulus yarn weaving method is the same as the second way. Tensile force changes are measured as Figure 9 The low modulus area shown is increased to 150%.

Abstract

The invention is called the design principle and production method of flexible materials with segmental deformation modulus and strength, and relates to a fabric with segmental modulus and strength during deformation, especially a fabric composed of materials with different moduli. Through structural design, a flexible material with different modulus and strength in different deformation stages can be realized by the characteristics of structural changes during the dynamic deformation process. The technical scheme of the invention is: adopt at least high / low two kinds of tensile modulus materials to weave to form segmental modulus fabric. When the fabric is in the low deformation stage, it exhibits low modulus characteristics, which can effectively maintain the freedom of movement of human joints and muscles. As the deformation increases, the high modulus materials in the fabric structure begin to stretch, rub and transfer between materials, so that the modulus of the fabric gradually increases. When the fabric reaches the stage of high deformation, it exhibits high modulus characteristics, which can effectively prevent damage caused by excessive stretching of human joints and muscles during exercise.

Description

technical field [0001] The invention relates to a fabric with segmented modulus and strength during deformation, especially a fabric composed of materials with different moduli. Through structural design, it can be realized in different structures due to the characteristics of structural changes in the process of dynamic deformation. A flexible material with different modulus and strength during the deformation phase. technical background [0002] With the improvement of living standards, people pay more and more attention to their own health, and exercise and fitness have more or less entered everyone's daily life, but the subsequent physical injury has also brought great harm to people. big trouble. Therefore, we have developed a fabric that can protect the body's joints and muscles during exercise, so that the joints and muscles can move freely and freely within a certain range, and can provide appropriate protection when the limit is exceeded. Smart materials have beco...
