Description

Technical Field

[0001] This invention relates to the field of textile technology, specifically to a wool napped fabric and its preparation method. Background Technology

[0002] In the textile industry, napped fabrics possess a unique appearance, soft hand feel, and excellent warmth retention. Traditional napped fabrics generally employ three structural methods: terry loop, padding, and plush. Terry loop fabrics are created by creating nap through loop formation. Based on the direction of the loops, they can be categorized as overlocked and underlocked. Overlocked loops are primarily used for double-sided napping, while underlocked loops are mainly used for single-sided napping. Underlocked loops, with one side flat and the other looped, tend to have the loop yarns visible on the flat surface, creating a "show-through" problem. This not only affects the fabric's appearance but can also lead to pilling and fuzzing, reducing fabric quality.

[0003] Currently, existing manufacturing processes mainly improve the "background showing" problem by adjusting the yarn, changing the manufacturing process, and altering the knitting machine needle curve. However, for yarns with high bending resistance, such as wool and glass fiber, the improvement effect of the above methods is not ideal, and it is difficult to completely avoid the "background showing" problem.

[0004] Therefore, for yarns with high bending resistance such as wool, how to obtain a napped fabric that reduces "background exposure" is a technical problem that needs to be solved. Summary of the Invention

[0005] To address the above problems, the present invention aims to provide a wool napped fabric and its preparation method. Compared with the prior art, the napped fabric provided by the present invention uses double-sided fabric as the base fabric and utilizes the loop structure on the surface of the double-sided fabric to form a napped surface, which can effectively solve the problem of "showing the base" and achieve a full and highly warm napped effect.

[0006] To achieve this objective, the present invention adopts the following technical solution: In a first aspect, the present invention provides a wool napped fabric, wherein the wool napped fabric is obtained by double-sided napping. One side of the double-sided fabric is a flat side, and the other side is a loop side. The loop side is napped to obtain a raised side. The terry cloth surface is made of nylon 66DTY and shrink-resistant wool tightly spun, and the terry cloth surface has a terry cloth structure, which is a shrink-resistant wool tightly spun. The flat surface is woven from nylon-covered Lycra core-spun yarn.

[0007] This invention, based on double-sided fabric, features a specially designed terry loop surface. It uses nylon-lycra-wrapped core-spun yarn as the face yarn, nylon 66DTY as the connecting yarn, and shrink-resistant wool compact yarn as the terry loop yarn, woven together to create the fabric. The flat and terry loop surfaces are firmly bonded, forming a stable three-dimensional structure. This prevents the terry loop yarn from being pulled out or shifted during napping or use, significantly reducing or even eliminating the "backing material showing" problem. Furthermore, the shrink-resistant wool compact yarn has high bending resistance and good resilience, and after napping, it can form a pile fabric with a strong three-dimensional effect, high density, good softness, and excellent warmth retention.

[0008] Preferably, the nylon 66DTY includes 30D / 34F nylon 66DTY.

[0009] Preferably, the shrink-resistant wool compact yarn comprises 72N / 1 shrink-resistant wool compact yarn.

[0010] Preferably, the nylon-wrapped Lycra core-spun yarn comprises 70D nylon-wrapped 40D Lycra core-spun yarn.

[0011] In this invention, 30D / 34F nylon 66DTY is preferred for nylon 66DTY, 72N / 1 nylon compact yarn is preferred for shrink-resistant wool compact yarn, and 70D nylon-wrapped Lycra core-spun yarn is preferred for nylon-wrapped 40D Lycra core-spun yarn. This ensures that the face yarn, i.e., the nylon-wrapped Lycra core-spun yarn, has good resilience. By reasonably controlling the weight and the size of the loops, the loops have sufficient stiffness and three-dimensionality. This avoids the loops being too small due to the nylon 66DTY yarn being too coarse, while also reserving sufficient space for loop formation, ultimately resulting in a strong three-dimensionality and stable shape of the loops.

[0012] Preferably, the double-sided fabric is woven using a double-sided knitting machine.

[0013] Preferably, the double-sided knitting machine includes a 30-inch 28-needle double-sided knitting machine.

[0014] Preferably, the basis weight of the double-sided fabric is 200-330 g / m². 2 For example, it could be 200g / m 2 210g / m 2 220g / m 2 230g / m 2 240g / m 2 250g / m 2 260g / m 2 270g / m 2 280g / m 2 290g / m 2 300g / m 2 Or 330g / m 2 However, this does not limit the listed values; other unlisted values ​​within the range are also applicable.

[0017] In this invention, by specifically adopting the above-mentioned triangular arrangement, space can be reserved on the loop surface for the tight spinning of anti-shrink wool, so that the loop naturally bends upward during the rebound process of the core-spun yarn.

[0081] Comparative Example 1 This comparative example provides a wool napped fabric, which differs from Example 1 only in that the 70D nylon-wrapped 40D Lycra core-spun yarn is replaced with 70D nylon.

[0082] Comparative Example 2 This comparative example provides a wool napped fabric, which differs from Example 1 only in that the 72N / 1 shrink-resistant wool compact yarn is replaced with 150D polyester.

[0083] Comparative Example 3 This comparative example provides a wool napped fabric, differing from Example 1 only in that the flat surface is woven with 70D nylon wrapped with 40D Lycra core-spun yarn, with a 50N yarn length of 13.5cm, while the terry surface is woven with 72N / 1 shrink-resistant wool tightly spun yarn, with a 50N yarn length of 26cm, and its triangular arrangement is as follows: Figure 2 As shown.

[0084] The pilling effect of the wool napped fabrics obtained in the above embodiments and comparative examples was tested.

The pilling condition of the napped surface was evaluated using the RTPT random flipping pilling test ISO12945-3, with a test time of 30 minutes. The severity of pilling was assigned to a grade as shown in Table 1, where grades 1-5 indicate decreasing pilling degree, grade 5 indicates no surface change, and grade 1 indicates severe pilling.

[0085] The shedding rate of the wool napped fabrics obtained in the above embodiments and comparative examples was evaluated using AATCC TM212-2021 OptonB, as shown in Table 1.

[0086] The "background exposure" of the wool napped fabrics obtained in the above embodiments and comparative examples was statistically analyzed. The number of loops in a 5cm×5cm wool napped fabric was 5600. The number of "background exposures" is shown in Table 1.

[0087] The tactile feel of the wool napped fabrics obtained in the above embodiments and comparative examples was tested. The nap of the product was touched with the back of the hand, and the tactile feel was recorded, as shown in Table 1.

[0088] The warmth retention of the wool napped fabrics obtained in the above embodiments and comparative examples was tested, and the Clo values ​​were statistically analyzed, as shown in Table 1.

[0089] Table 1 As can be seen from Table 1: (1) As can be seen from the data of Examples 1-5, the clo value of the wool napped fabric provided by the present invention reaches 0.45Clo or above, the Martindale pilling test reaches level 4-5, the RTPT random pilling test reaches level 4, and there is no "exposed bottom" problem.

[0090] (2) As can be seen from the data of Examples 1 and 4-5, the present invention can further improve the fullness of wool napped fabric and improve its warmth by controlling the fineness of the shrink-resistant wool compact spinning and the nylon-wrapped Lycra core-spun yarn.

[0091] (3) As can be seen from the data of Example 1 and Comparative Examples 1-2, the present invention can improve the fullness of the loops and the warmth retention effect by using nylon-wrapped Lycra core-spun yarn to weave a flat surface and using shrink-resistant wool to tightly weave a loop structure. The napped surface is also good at resisting pilling.

[0092] (4) As can be seen from the data of Example 1 and Comparative Example 3, the double-sided fabric structure provided by the present invention is less likely to have the problem of "showing the bottom" compared with existing wool napped fabrics such as Comparative Example 3, and has a lower shedding rate and better warmth retention.
