Description

Technical Field

[0001] This utility model relates to the textile field, specifically to a warm and easy-care fabric. Background Technology

[0002] As winter temperatures drop, thermal clothing often uses a napping process to thicken the fabric surface and reduce airflow, thus enhancing warmth. The nap material in these garments isn't uniform, primarily using pure cotton, pure polyester, or polyester-cotton blends. However, different nap materials exhibit significant differences in performance during actual use. Cotton, being a natural fiber, inherently has shorter fiber length and less uniformity. This results in several drawbacks when pure cotton or polyester-cotton blends are napped: the pile arrangement is less uniform, creating a messy appearance; the pile length is generally shorter, making it difficult to form a thick, dense insulating layer; and the pile's bond to the fabric base is insufficient, leading to significant shedding during daily wear, washing, or friction, affecting both the garment's appearance and causing inconvenience to the wearer. Utility Model Content

[0003] Based on the above background, this utility model provides a warm and easy-to-care-for fabric, using the following solution: A warm and easy-care fabric is made of six-way knitting, with the first and fourth ways using fixed yarn knitting: the knitting needles gather loops and the purling needles form loops to create an intermediate layer, wherein the fixed yarn is polyester. The second and fifth lines form the front side of the fabric, which is woven into a plain weave structure from cotton / modal blended yarn; The third and sixth threads form a piled surface, which is formed by alternating loops and floats of piled yarn, which are distributed in an interlaced manner to form loops that protrude on the reverse side of the fabric. The piled yarn is a double polyester yarn. The count of the pile yarn is coarser than that of the fixed yarn, and the F number of the pile yarn is higher than that of the fixed yarn.

[0004] Furthermore, the cotton / modal blended yarn has a specification of 32S / 1, the polyester of the fixed yarn has a specification of 50D / 36F, and the polyester of the napped yarn has a specification of 150D / 144F.

[0005] Furthermore, the polyester in the napped yarn is a functional polyester, such as polyester yarn with a 4C groove structure cross-section; or polyester containing aerogel functional powders, such as volcanic rock powder, zinc element, seaweed polysaccharide and other nanocomposite powders.

[0006] Furthermore, the blending ratio of cotton to modal in cotton / modal blended yarn is 50:50.

[0007] Furthermore, the cotton in the cotton / modal blended yarn is Pima cotton and linters cotton, and the modal is Lenzing Modal.

[0008] The fabric produced by the above method has the following beneficial effects: The fabric is woven from three types of yarns. The main component is polyester (theoretically 66%), with the addition of cotton / modal fibers with high moisture regain (theoretically 34%), which can reduce charge accumulation and static electricity. At the same time, the cotton / modal blended yarn provides a soft hand feel to the fabric, and its excellent properties as the front side of the fabric in dyeing or printing can give the fabric a bright color effect. The trendy combination makes the fabric less prone to fading, whitening, hardening, and wrinkling after washing, and easy to care for.

[0009] The napped surface of the fabric is composed of coarser, high-filament napping yarn and finer, low-filament fixing yarn, forming a textured, honeycomb-like appearance. The loops woven from the napping yarn protrude from the surface, while the floats are bound between the front and back sides of the fabric by the fixing yarn, making them invisible on the back side. The fixing yarn, due to its finer yarn count, has loops recessed on the back side of the fabric. During napping, the protruding napping yarn is pulled out and breaks to form the napped surface, while a small portion bound by the fixing yarn remains un-napped. This protects the napping yarn from complete breakage and, with the fixing yarn providing reinforcement, prevents it from shedding fibers.

[0010] The honeycomb-like appearance created by the fabric's structure allows for the retention of more still air and space in the recessed areas, making the fabric fluffier and warmer. Using polyester with a 4C cross-section increases the fiber's specific surface area, trapping even more still air and further optimizing the fabric's warmth. Similarly, using polyester containing aerogel functional powder provides insulation. The volcanic rock functional powder absorbs infrared rays released by the human body and resonates with the body, improving microcirculation. The heat-generating yarn directly contacts the body, further enhancing the fabric's warmth. Attached Figure Description

[0011] Figure 1 This is a coil diagram of the present invention.

[0012] Figure 2 This is a reverse view of the present invention.

[0013] In this context, × represents the protruding part on the reverse side, and 0 represents the concave part on the reverse side. Detailed Implementation

[0014] The present invention will be further explained below with reference to the embodiments. Example

[0015] Yarn: 32S / 1 compact Siro-spun cotton / modal blended yarn, spun by compact Siro spinning, with a twist of Z twist 800t / m and a twist coefficient of 340. Fixing yarn: 50D / 36F DTY light mesh semi-dull polyester, which serves to connect the front and back sides and fix the pile yarn.

[0016] Fluffy yarn: 150D / 144F DTY lightweight semi-dull polyester double yarn, meaning two 150D / 144F polyester yarns are woven in simultaneously. This polyester has a 4C grooved cross-section. Compared to a regular circular cross-section, this makes the yarn fluffier and has a larger surface area, which can trap a large amount of still air. It has antibacterial, warmth-retaining, far-infrared heating, and mite-inhibiting functions. The original yarn has these functions and good durability.

[0017] like Figure 1 As shown, the fabric consists of 6 rows forming a complete cycle. The 2nd and 5th rows in the diagram form the front side of the fabric, which is woven from the yarn into a plain weave structure. In the diagram, lines 1 and 4 form the middle layer, which is woven with fixed yarn. The down stitches form loops, and the up stitches form circles. The polyester yarn is not visible on the front, but forms sesame-like dots on the back, which serves to connect the front and back and fix and bind the pile yarn. In the diagram, the 3rd and 6th lines form the napped surface, which is formed by alternating loops and floats of napped yarn, interwoven to create loops that protrude on the reverse side of the fabric. The floats are covered and fixed by loops woven from fixed yarn, so they are not exposed on the reverse side.

[0018] The yarn length is 29cm / 100G, the fixed yarn length is 26.5cm / 100G, the pile yarn length is 27cm / 100G, the machine width is 210.8cm, and the machine weight is 260g. The proportions of the three types of yarn are as follows: face yarn / fixed yarn / pile yarn: 33.8% / 9.3% / 56.9%.

[0019] The reverse side of the fabric is woven from 150D / 144F polyester double yarn (as the napping yarn) and 50D / 36F polyester, as shown in the schematic diagram of the reverse side of the fabric. Figure 2 As shown, the yarns are interspersed and evenly distributed like sesame seeds. The ratio of the denier count of the two yarns is 6:1. Due to the difference in thickness, a distinct honeycomb-like appearance is formed on the fabric surface. The raising yarn protrudes from the outermost surface, which facilitates the raising process later. The fixing yarn is recessed and hidden inside the fabric, making it difficult to pull during raising. It plays a role in fixing the raising yarn and preventing the yarn from breaking completely and causing shedding. The recessed areas can retain more still air and space, making the fabric fluffier and warmer. Example

[0020] The difference between this embodiment and Embodiment 1 is that the polyester used in the napped yarn is aerogel functional polyester, which is a functional polyester made by processing volcanic rock ore, aerogel, seaweed polysaccharide, zinc element and anti-mite properties into masterbatch, and then spinning it.

[0021] Fabrics made from this functional polyester have better warmth retention and also have antibacterial and anti-mite effects.

[0022] The fabric prepared as described above was tested: 1. Pilling and fuzzing grade 4, GB / T 4802.1-2008 (780cN, 0 pilling cycles, 600 pilling cycles). 2. Light fastness grade 4, GB / T 8427-2019 Method 3 (first stage); 3. Color fastness to light and perspiration is grade 4, Q / LLZG 302-2022 (second stage); 4. Water wash appearance * discoloration level 4, GB / T 8629-2017 4N (plus 2 machine washes); 5. Color fastness to rubbing (dry) Grade 4 (GB / T 3920-2008); 6. Dimensional change rate: -3.4% in the warp direction after washing, -2.6% in the weft direction after washing, GB / T 8629-2017 4N, hang to dry; 7. Shedding fibers: Grade 3 (Q / LLZG 312-2022).

[0023] The above specific embodiments are only preferred embodiments of this utility model. Any adjustments and improvements made by those skilled in the art based on this utility model that do not possess substantial features or progress should fall within the protection scope of this utility model.
