Detailed Description
The utility model provides an elastic weft-knitted double-sided random cutting fabric, which is used for making the purposes, technical schemes and effects of the utility model clearer and more definite, and is further described in detail below by referring to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
In the description of the present utility model, it should be understood that "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present utility model, unless otherwise indicated, the meaning of "a plurality" is two or more.
Referring to fig. 1, the utility model provides an elastic weft-knitted double-sided random fabric, which comprises a cloth surface layer 1, a first connecting layer 2, a middle layer 3, a second connecting layer 4 and a cloth bottom layer 5 which are sequentially stacked, wherein the cloth surface layer 1 and the cloth bottom layer 5 are yarn layers, the first connecting layer 2 and the second connecting layer 4 are hot-melt spandex layers, and the middle layer 3 is a high-temperature-resistant spandex layer. The hot-melt spandex layer is heated and melted in the heat setting process of the fabric, the yarn layer and the high-temperature-resistant spandex layer are adhered, all layers of structures of the fabric are connected with each other to form a whole, the fabric can be cut in any shape, and the edge of the cut fabric cannot be off line. The high-temperature resistant spandex layer can be kept stable in the embryo fixing process, does not generate heat melting, only can be subjected to heat setting, and ensures that the fabric still keeps enough elasticity after being subjected to the embryo fixing process.
Preferably, the melting point of the hot-melt spandex is below 200 ℃, and the melting point of the high-temperature-resistant spandex is above 230 ℃. According to the melting point of the hot-melt spandex, the embryo fixed temperature is generally 150-200 ℃, and the melting point of the high-temperature-resistant spandex is at least 30 ℃ higher than the embryo fixed temperature, so that the structural change caused by heating and melting can not occur, and the elasticity and strength of the spandex are maintained.
Preferably, the melting point of the hot-melt spandex is 160-180 ℃, and the melting point of the high-temperature-resistant spandex is 230-245 ℃.
Preferably, the first connection layer 2 and the second connection layer 4 are net-shaped. The hot-melt spandex layer of the reticular structure has better elasticity, can be adhered with a plurality of fibers with different trend, and has more compact connection of each hierarchical structure of the fabric. When the fabric is cut, any yarn fiber or high Wen Anguan resistant yarn at the cutting position is still adhered by the hot-melt polyurethane layer, so that the conditions of open mouth and off-line can not occur. Therefore, the random cutting fabric can be used for self-cutting to perform secondary creation, cutting loss can be reduced in the clothing manufacturing process, the process (without hemming) is reduced, and the production efficiency is improved.
Preferably, the yarn layer is a staple yarn layer, a filament yarn layer or a staple-filament blended yarn layer. The types of the yarn layers of the cloth surface layer and the cloth bottom layer can be the same or different, for example, the cloth surface layer and the cloth bottom layer can both adopt a short fiber yarn layer, or the cloth surface layer adopts a short fiber yarn layer, and the cloth bottom layer adopts a short fiber filament yarn blending yarn layer, so that the cloth surface layer and the cloth bottom layer can be combined arbitrarily according to actual needs.
The short fiber yarn can be pure spun or blended yarn of cotton, hemp, regenerated cellulose fiber (such as modal and tencel) and the like. The filament yarn can be pure spun or blended yarn such as nylon, terylene and the like.
The filaments are multi-F chemical fiber filament yarns, and the multi-F chemical fiber filaments can be 24F, 36F, 48F and 144F chemical fiber filaments. The multi-F-number chemical fiber filament yarn can form a non-flowing air layer in the middle of the fabric, so that the heat preservation effect of the product can be greatly improved, and the initial modulus of the multi-F-number chemical fiber filament yarn is smaller than that of a single F-number chemical fiber filament yarn, so that the fabric is softer, the bottom penetrating and filament hooking are not easy to occur, the meat binding phenomenon is not caused after edge cutting, and the fabric has a better skin-friendly effect.
The utility model has high pull-out (horizontal 320/vertical 280) and can be used for manufacturing the code-equalizing motion built-in device. The first connecting layer and the second connecting layer are netlike and are matched with the middle layer, so that the fabric has the characteristic of four-side elasticity, and omnidirectional movement is ensured to be free. When the fabric is manufactured, different yarn fineness, yarn length and spandex can be selected to form the fabric with different stretching opening degrees and elastic strength, and when the sports underwear is manufactured, the fabric with different performances can be provided according to different functional areas, so that a plurality of choices are provided for designers.
