Description

Technical Field

[0001] This utility model relates to the field of knitted fabrics, and in particular to a fluffy, warm, light-absorbing and heat-generating fabric. Background Technology

[0002] Thermal fabrics have always been an important research area in the textile industry, especially in cold regions and winter clothing, where warmth retention is one of the key indicators for measuring fabric quality. Traditional thermal fabrics mainly include natural fibers such as wool, down, and cotton, as well as some synthetic fibers.

[0003] However, these traditional fabrics have some limitations, such as wool being prone to shrinkage, down being prone to leakage, and cotton fabrics having limited warmth retention.

[0004] Therefore, it is necessary to propose a fluffy, warm, light-absorbing, and heat-generating fabric to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a fluffy, warm, light-absorbing and heat-generating fabric to solve some limitations of traditional fabrics, such as wool shrinking easily, down leaking easily, and cotton fabric having limited warmth retention.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fluffy, warm, light-absorbing, and heat-generating fabric, comprising:

[0007] A high-fluffy outer layer, wherein the high-fluffy outer layer is provided with upper and lower layers;

[0008] A thermal insulation inner fiber layer is disposed between two upper and lower high-fluffy outer layers;

[0009] The inner heat-insulating fiber layer is made of light-absorbing and heat-generating polyester yarn, and a pile layer is formed on the upper and lower surfaces respectively through a napping and shearing process.

[0010] The fleece layer is made of polyester fiber yarn, and the fleece layer and the inner insulating fiber layer are intertwined to form an integrated structure.

[0011] Preferably, the pile layer includes a first pile layer and a second pile layer with different thicknesses, and the thickness ratio of the first pile layer and the second pile layer is 1:1.5-2.5.

[0012] Preferably, a light-absorbing and heat-generating polyester fiber layer is interspersed within the fluff layer.

[0013] Preferably, the blending ratio of the ordinary polyester fiber and the light-absorbing and heat-generating polyester fiber is 3:7-7:3.

[0014] Preferably, the fabric has a weight of 80-150 g / m² and a fill power of ≥15 cm³ / g.

[0015] Preferably, the napping process has a napping height of 0.5-2mm, and the trimming process has a trimming accuracy of ±0.1mm.

[0016] Preferably, the thickness of the first pile layer (31) is 0.3-0.5 mm, and the thickness of the second pile layer (32) is 0.6-1.2 mm.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. By forming fleece layers on both the upper and lower surfaces of the inner insulating fiber layer, the fabric's warmth retention is significantly enhanced by utilizing the air insulation effect of the fleece layers. Furthermore, the inner insulating fiber layer, made of light-absorbing and heat-generating polyester yarn, absorbs external light and converts it into heat, further enhancing the warmth retention effect.

[0019] 2. Compared with traditional thermal fabrics, this fabric provides the same warmth while being lighter, achieving a perfect combination of warmth and lightness. In addition, the high loft and special fiber structure of the fabric ensure good breathability, effectively wicking away sweat and moisture emitted by the body and keeping the wearer dry.

[0024] This utility model provides, for example Figures 1-3 The illustrated fabric is a fluffy, warm, light-absorbing, and heat-generating material, comprising:

[0025] High-loft outer layer 1 has two layers, upper and lower. The double-layer structure not only gives the fabric a good appearance and texture, but also effectively enhances the overall warmth performance of the fabric.

[0026] The inner heat-insulating fiber layer 2 is disposed between the upper and lower high-fluffy outer layers 1;

[0027] Among them, the inner heat-insulating fiber layer 2 is made of light-absorbing and heat-generating polyester yarn, and a pile layer 3 is formed on the upper and lower surfaces respectively through a napping and shearing process;

[0028] This is the core component that enables the fabric to retain warmth; it is made of light-absorbing and heat-generating polyester yarn. This special polyester fiber has unique light-absorbing properties, capable of absorbing external light and converting it into heat, thus providing the wearer with a continuous warming effect. Through napping and shearing processes, the upper and lower surfaces of the inner insulating fiber layer 2 are respectively formed into a fleece layer 3, further enhancing the fabric's warmth and softness.

[0029] The fleece layer 3 is also made of polyester fiber yarn, and it is intertwined with the inner insulating fiber layer 2 to form a tightly integrated structure. This integrated structure not only enhances the overall strength of the fabric, but also makes the insulation performance more evenly distributed, avoiding the problem of insulation layer shedding or shifting that may occur in traditional fabrics.

[0030] The fleece layer 3 includes a first fleece layer 31 and a second fleece layer 32 with different thicknesses. The thickness ratio of the first fleece layer 31 to the second fleece layer 32 is 1:1.5-2.5. The thickness of the first fleece layer 31 is 0.3-0.5mm, and the thickness of the second fleece layer 32 is 0.6-1.2mm. The differentiated thickness design allows the fabric to have different warmth retention effects in different parts, which can better adapt to the temperature needs of the human body, and at the same time, it can also increase the sense of layering and comfort of the fabric to a certain extent.

[0031] The fleece layer 3 contains interspersed layers of light-absorbing and heat-generating polyester fibers, further enhancing the fabric's warmth retention. This allows the fabric to more effectively convert absorbed light into heat, providing the wearer with a more lasting and stable warmth. By rationally controlling the distribution and density of the light-absorbing and heat-generating polyester fibers, the fabric's optimal warmth retention performance can be achieved in various environments.

[0032] The blending ratio of ordinary polyester fiber to light-absorbing and heat-generating polyester fiber is 3:7-7:3, which can be adjusted according to different usage needs and environmental conditions to achieve optimal warmth and comfort. For example, in cold environments, the proportion of light-absorbing and heat-generating polyester fiber can be appropriately increased to improve the fabric's warmth retention; while in relatively warm environments, the proportion of ordinary polyester fiber can be appropriately increased to improve the fabric's breathability and comfort.

[0033] The fabric weighs 80-150g / m² and has a loft of ≥15cm³ / g. The high loft design allows the fabric to maintain good breathability and softness while keeping it warm, so that wearers can enjoy a comfortable wearing experience in cold weather.

[0034] The napping process has a pile height of 0.5-2mm, while the shearing process has a trimming precision of ±0.1mm. During production, the napping process controls the pile height to 0.5-2mm. This precise pile height ensures that the pile layer 3 has excellent warmth retention and softness, while avoiding problems such as rough fabric surface or pilling caused by excessive pile. The shearing process has a trimming precision of ±0.1mm. This high-precision trimming process ensures the surface smoothness and uniformity of the pile layer 3, resulting in a high quality standard for the fabric in both appearance and feel.

[0035] This utility model also discloses a dyeing and finishing method for high-elasticity and warm knitted fabrics, including the following steps:

[0036] Step 1: Pretreatment. Use a specific surfactant to pretreat the fabric, adjust the pH value to 6.5-7, the temperature to 80℃, and the time to 20 minutes to make it suitable for subsequent dyeing.

[0037] Step 2: Use macromolecular disperse dyes and sodium acetate buffer to adjust the pH to 4.5 for dyeing to ensure uniform dye fixation;

[0038] Step 3: After dyeing, dehydrate to 20% liquid content, then pass through an open-width setting machine for one dip and one roll, and add a specific combination of napping agents to achieve the fluffy and soft effect required for final finishing.

[0039] Step 4: Raising finishing. Use a 24-roll straight and curved needle raising machine to raise the fabric. The raising process is carried out in a gradual manner, passing through a set of 7 raising machines to observe the pile length and density to achieve the desired style.

[0040] Step 5: Tensile setting. Use a tenter frame to heat set the fabric at 130 degrees Celsius and 25 yards per minute. The fabric width should be 3cm wider than the finished product width, and the weight per square meter should be 15 grams heavier than the finished product weight. The airflow should be low.

[0041] Step Six: Combing and Shearing. The fabric after heat drying is combed and sheared. The combing is done using the new Xuhuan special-shaped roller combing machine. The fabric hair is sheared to the required height according to specific parameters.

[0042] Step 7: Shaking the pellets. Use a shaking drum to shake the pellets with hot air and steam to achieve a full-bodied texture.

[0043] In the pretreatment step, the pH value is adjusted to 6.5-7, the temperature is 80℃, and the holding time is 20 minutes.

[0044] The pH value is adjusted to 4.5-5 using acetic acid in the dyeing process. Large molecular weight disperse dyes and auxiliaries that can be dyed under weakly acidic conditions are used. The dyeing temperature is 130℃ and the holding time is 30-45 minutes.

[0045] The printing of light-absorbing and heat-generating materials is carried out using brushing, combing, and shaking methods. The fabric structure has sufficient thickness and gaps, resulting in excellent heat preservation effects.
