Furthermore, the cotton yarn is wrapped around the polyester filaments, reducing direct friction and thus minimizing pilling.

Description

Technical Field

[0001] This utility model relates to a moisture-wicking and breathable polyester fabric, belonging to the technical field of polyester fabrics. Background Technology

[0002] Cotton, as the most commonly used natural cellulose fiber, has excellent moisture absorption. Polyester, as a commonly used synthetic fiber, has high strength and abrasion resistance. Therefore, cotton-polyester fabric has become a conventional material. Using polyester yarn or filament on the inner side and cotton-containing yarn on the outer side can achieve good moisture absorption and keep the inner side dry, improving wearing comfort. Woven fabrics use interwoven warp and weft yarns. Because the warp and weft yarns interweave, there are gaps between the yarns, resulting in good breathability. The density of the warp and weft yarns can be adjusted to regulate the gaps between the yarns, thus adjusting breathability. However, because the cotton fibers used are short fibers, the fabric will pill when subjected to friction. Therefore, how to develop a moisture-wicking and breathable polyester fabric with good anti-pilling properties has become a problem to be solved. Utility Model Content

[0003] The purpose of this invention is to provide a moisture-wicking and breathable polyester fabric, which uses cotton yarn wrapped with polyester filaments to reduce pilling and fuzzing.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] Combination Figure 1 and Figure 2This embodiment provides a detailed description. The moisture-wicking and breathable polyester fabric involved in this embodiment is woven from warp and weft yarns. The warp yarns include surface warp yarns and inner warp yarns, and the weft yarns include surface weft yarns, inner weft yarns, and connecting weft yarns. The surface warp and surface weft yarns interweave to form surface layer 1, and the inner warp and inner weft yarns interweave according to a perforated structure to form inner layer 2; the connecting weft yarns connect surface layer 1 and inner layer 2. The connecting weft yarns are made of transparent nylon monofilament with a diameter of 0.1 mm.

[0021] The yarns used for the surface warp and weft are polyester-cotton core-spun yarns. These yarns include a core yarn 11 and a first polyester filament 12 and a second polyester filament 13, which are interwoven and cross-wound around the outside of the core yarn 11. The first polyester filament 12 and the second polyester filament 13 are wound in opposite directions. The cotton yarn used has a fineness of 18.5 tex, and the first polyester filament 12 and the second polyester filament 13 have a specification of 38.9 dtex / 144F. The pitch of the first polyester filament 12 and the second polyester filament 13 during winding is 2.5 mm.

[0022] The inner warp and weft yarns comprise fine denier polyester filaments with a twist of 300-500 twists / m and a Y-shaped or cross-shaped cross-section. The fine denier polyester filaments used are 72D / 96F. The Y-shaped or cross-shaped cross-section of the filaments has grooves on its surface, which, due to the wicking effect, gives the polyester filaments excellent moisture absorption and wicking properties. Furthermore, the cotton yarn used in the outer layer has good moisture absorption, while the polyester filaments used in the inner layer have poor moisture absorption. Therefore, the outer layer 1 can absorb moisture, thus keeping the inner layer 2 dry.

[0023] Furthermore, in the outer layer 1 and the inner layer 2, there is at least a gap of one-third of the corresponding yarn diameter between two adjacent outer layer warp yarns, outer layer weft yarns, inner layer warp yarns and inner layer weft yarns, thereby giving the fabric good breathability.

[0024] Example 2

[0025] Combination Figure 3 This embodiment will be described in detail below. The moisture-wicking and breathable polyester fabric involved in this embodiment differs from that in Embodiment 1 in that: the inner warp and weft yarns further include bicomponent polyester filaments arranged parallel to the fine denier polyester filaments. The cross-section of each bicomponent polyester filament includes a core layer 21 and a sheath layer 22. The core layer 21 is PET, and the sheath layer 22 is LPET. The fineness of each bicomponent polyester filament is 1.38 dtex, and the F number is 36. Furthermore, the mass ratio of the core layer 21 to the sheath layer 22 is 1:1. LPET is low-melting-point polyethylene terephthalate with a melting point of approximately 105°C. PET is ordinary polyethylene terephthalate with a melting point of 255-265°C.

[0026] The prepared fabric is hot-rolled to form uniformly distributed rolling points. At the rolling points, LPTE melts and bonds with adjacent fibers, thereby stabilizing the pores formed by the perforated structure.

[0027] Example 3

[0028] The moisture-wicking and breathable polyester fabric involved in this embodiment differs from that in Embodiment 2 in that the first polyester filament 12 and the second polyester filament 13 are semi-dull or fully dull polyester filaments. The cotton yarn is antibacterial cotton yarn. In this embodiment, fully dull polyester filament is selected. Fully dull polyester filament also has UV protection due to the use of titanium dioxide as a matting agent.

[0029] Another difference from Example 2 is that both the first polyester filament 12 and the second polyester filament 13 have a twist of 200-300 twists / m and the twist direction is the same. The twisted first polyester filament 12 and the second polyester filament 13 can reduce pilling and fuzzing.

[0030] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
