For this reason, we propose a suede heating fabric. Summary of the Invention

[0005] The object of the present invention is to provide a suede heating fabric to solve the existing problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a suede heating fabric, comprising the following steps:

[0007] Step 1: Select high-quality fiber raw materials. The satin base of velvet is generally made of natural fibers such as linen and silk, while the pile of velvet fabric can be made of chemical fibers such as polyester, acrylic, etc.

[0008] Step 2: After the selected raw materials are processed, they will go through the spinning process. In this process, the raw materials will first be rewound and soaked, and then go through multiple processes such as stretching, processing, oiling, and blanking to finally form thick yarn or strands;

[0009] Step 3: Weaving is one of the most important steps in the production of velvet fabrics. The coarse yarn or strands that have been spun and pre-weaved are loaded into the loom. After the weaving process, the satin base fabric and the velvet are integrated into a soft and fluffy velvet.

[0010] Step 4: Although the woven velvet can be used directly, it needs to be dyed due to its single color. The dyeing process has different steps according to different requirements, including softening, soaking, bleaching, dye addition, and drying.

[0011] Step 5: The fiber material placed in the water medium is opened into single fibers, and different fiber materials are mixed to form a fiber suspension slurry. The suspension slurry is transported to a web-forming organization, and the fibers are formed into a web in a wet state and then reinforced into a cloth;

[0012] Step 6: The heating yarn can be prepared by blending. By changing the blending components and blending ratio of the yarn, using fibers with heat storage capacity and fibers with high moisture absorption integral heat, and appropriately adjusting the blending ratio, the yarn can obtain good heating performance. In addition to blended yarns, there are also core-spun yarns and covered yarns, which can be combined with heating materials to prepare heating yarns;

[0013] Step 7: Adding a moisture-absorbing and heat-generating finishing agent can improve the fabric's moisture absorption, air permeability, and moisture regain to a certain extent, enhance the diffusion capacity of moisture in the inner layer of the fabric, make the heat generated by moisture absorption more evenly distributed, realize the fabric's moisture absorption and heat generation, and heat storage and moisturizing functions, thereby improving the thermal comfort of the product;

[0014] Step 8: Add a moisture-absorbing and heat-generating finishing agent with moisture-absorbing, moisturizing, and heat-generating functions to viscose, polyester, acrylic, and other fiber fabrics through conventional finishing processes such as padding, dipping, and spraying, thereby imparting heat storage, warmth retention, and breathability to the fiber fabrics. This method has a low development cost and can be used in the same bath with softeners and resins to further enhance the wearing comfort of the fabrics.

[0015] Step 9: Use a special process to change the internal structure of the yarn, so that a hollow layer is formed inside the yarn. The physical principle of hollow insulation is adopted. The yarn continuously absorbs and releases moisture, absorbs water in the air and water vapor discharged by the human body to produce a physical reaction, thereby achieving the effect of moisture absorption and heat generation.

[0016] Preferably, in step 4, the woven velvet is subjected to a satin finishing process, mainly to eliminate the hempiness of the satin base fabric, and the suede finishing process is mainly to improve the air permeability and softness of the suede surface.

[0017] Preferably, in step 7, nylon 72.5 and spandex 27.5 can be added, and some heating potion can be mixed into the yarn for blending, so that the yarn also has the function of generating heat.

[0018] Preferably, the nylon 72.5 velvet fabric adopts dry-spinning ultra-fine special-shaped cross-section technology to make the fabric more fluffy. In addition, the erected fluff can also increase the amount of still air, so the velvet fabric is very warm.

[0019] Preferably, in step 1, the suede heating fabric can be made of suede fabric, which contains a certain proportion of spandex and has good elasticity; it usually adopts reactive printing and dyeing, and will not fade or discolor after repeated washing; it has good air permeability, is not easy to pilling, and is skin-friendly.

[0020] Preferably, the suede fabric can be washed by hand or by machine. When washing by hand, it must be rinsed thoroughly to avoid bacterial growth. Because it is a chemical fiber fabric, it should not be ironed during the drying process. There are fine hairs on the surface of the suede fabric, which will become hard and feel worse after ironing.

[0021] Preferably, in step 9, a far-infrared heating raw material is used, and a new type of heating fiber into which far-infrared ceramic particles are integrated during the spinning process is spun into knitting yarn. The far-infrared heating raw material has the function of absorbing and emitting far-infrared rays, and can emit far-infrared rays of 4 to 14 μm at room temperature and lower temperatures.

[0022] In the present invention, nylon 72.5 and spandex 27.5 are used, and some heating potions are added to the yarn for blending, so that the yarn also has the function of heating. The suede fabric can be washed by hand or by machine. When washing, it is necessary to rinse it thoroughly to avoid the breeding of bacteria. Because it is a chemical fiber fabric, it should not be ironed during the drying process. It has a soft feel and bright color, is not easy to mold, and will not cause allergies. It has good absorption, breathability and warmth retention. Nylon has excellent moisture absorption and breathability, is not easy to fade, yellow, wrinkle, or shrink, has a natural drape and wrinkle resistance, has a silky luster, and has an excellent texture.
