Description

Technical Field

[0001] This utility model relates to the field of knitted fabric technology, and in particular to an elastic jacquard fabric. Background Technology

[0002] Spandex is widely used in stretch knitted fabrics due to its excellent elasticity. However, while possessing superior elasticity, spandex also has some drawbacks, such as easy aging, poor dyeability, susceptibility to chlorine bleaching, high price, and a tendency for the fabric to curl at the edges. During use, frequent stretching forces cause spandex to age easily, leading to a significant loss of fabric elasticity and severely impacting its lifespan. Spandex itself is also difficult to dye; conventional dyes cannot color it. Furthermore, if the reduction washing process is insufficient after dyeing, yellowing may occur. Therefore, developing an elastic fabric that does not require spandex is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Attached Figure Description

[0019] Figure 1 This is a triangular diagram of a preferred embodiment of the present invention. Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] The elastic jacquard fabric of this embodiment includes cotton yarn and bicomponent polyester fiber. The elastic jacquard fabric is a double-sided fabric formed by weft knitting cotton yarn and bicomponent polyester fiber according to a jacquard weave, with one side being a jacquard surface and the other a plain weave surface. It has good skin-friendly breathability, comfort, crispness, and resilience.

[0022] In this embodiment, the jacquard stretch fabric uses bicomponent polyester fiber instead of spandex to impart elasticity to the fabric. Bicomponent polyester fiber has a unique spiral spring-like microstructure, allowing it to exhibit extreme elasticity without spandex. The crimped shape of the bicomponent polyester fiber gives the fabric a pleasant cotton-like feel, and when combined with cotton yarn, it results in a soft and full-bodied fabric. Bicomponent polyester fiber is resistant to chlorine bleaching, easy to dye, wrinkle-resistant, has excellent moisture absorption and quick-drying properties, excellent anti-pilling and anti-fuzzing properties, and a relatively high abrasion resistance.

[0023] In one feasible option of this embodiment, the bicomponent polyester fiber is a composite yarn of PBT and PET. The cotton yarn is a compact combed cotton yarn with a specification of 32S, and the bicomponent polyester fiber is a semi-dull DTY lightweight bicomponent polyester fiber with a specification of 55dtex / 36F.

[0024] The jacquard weave is a honeycomb jacquard weave, which gives the jacquard surface a three-dimensional embossed honeycomb effect, giving the elastic jacquard fabric a certain spatial performance and improving its breathability and moisture absorption and quick-drying properties.

[0025] The odd-numbered sections of the jacquard weave are made of bicomponent polyester fibers, while the even-numbered sections are made of cotton yarn.

[0026] The knitting process of the elastic jacquard fabric in this embodiment is as follows:

[0027] The knitting equipment is a double-sided weft circular knitting machine. The needle plate uses an AB needle arrangement, and the cylinder uses a BA needle arrangement. The yarn length for odd-numbered tracks is controlled at 31–35 cm / 100N, and the yarn length for even-numbered tracks is controlled at 27–29 cm / 100N. The upper triangular arrangement is as follows: Figure 1 As shown, “∧ or ∨” indicates a circle, “∩” indicates a cluster, and “—” indicates a floating line.

[0028] The smallest knitting cycle unit of a jacquard weave is formed by knitting a two-needle disc and a two-needle cylinder, and its structure is as follows:

[0029] Routes 1, 3, and 5: The needle trays are all circular, and the syringes are successively circular and floated;

[0030] Routes 7, 9, and 11: The needle trays are all in circles, and the syringes are successively floated and in circles;

[0031] Routes 2, 4, 6, 8, 10, and 12: All needle discs are floating thread, and all syringes are in a loop.
