Description

Technical Field

[0001] This utility model relates to the field of fabric technology, and in particular to a 100% polyester mechanical elastic waffle fabric. Background Technology

[0002] Existing sports elastic fabrics generally use elastic spandex material. However, spandex material is prone to aging. Frequent washing, chlorine bleaching, and ultraviolet radiation will accelerate the degradation of spandex. In addition, spandex fabrics are expensive, difficult to recycle, and may produce harmful gases when incinerated.

[0003] To overcome the above problems, mechanically elastic fabrics can be used. For example, patent CN105063859A discloses a mechanically elastic fabric formed by interlacing composite yarns. However, existing mechanically elastic fabrics have poor elasticity, wrinkle resistance, and softness. Utility Model Content

[0004] The purpose of this invention is to provide a 100% polyester mechanical elastic waffle fabric with functions such as wrinkle resistance, quick drying, and stable resilience.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This utility model discloses a 100% polyester mechanical elastic waffle fabric, which is a weft-knitted structure woven from plied elastic yarns. The plied elastic yarns are plied elastic yarns of polyester stretch textured yarns, and the surface of the fabric has a raised waffle texture.

[0007] Furthermore, the specifications of the twisted elastic yarn are DTY 139Dtex / 108F.

[0008] Preferably, the twisted elastic yarn is made by twisting polyester high-elastic yarn and ordinary polyester yarn, wherein the polyester high-elastic yarn has a specification of 50D / 36F and the ordinary polyester yarn has a specification of 75D / 72F.

[0009] Furthermore, the fabric weaving pattern uses 8 warp rows and 12 rows as the smallest cycle unit, wherein: in the 1st, 2nd, 3rd, and 4th warp rows, the 1st, 2nd, 3rd, and 4th rows are knit stitch loop structure units, and the 5th, 6th, 7th, 8th, 9th, 10th, 11th, and 12th rows are knit stitch round structure units; in the 5th, 6th, 7th, and 8th warp rows, the 1st, 2nd, 3rd, 4th, 5th, 6th, 11th, and 12th rows are purl stitch round structure units, and the 7th, 8th, 9th, and 10th rows are purl stitch loop structure units.

[0010] Preferably, the yarn length of the yarns woven in the 5th, 6th, 11th, and 12th rows is greater than the yarn length of the yarns woven in the 1st, 2nd, 3rd, 4th, 7th, 8th, 9th, and 10th rows.

[0011] The yarn lengths of the yarns woven in the 5th, 6th, 11th, and 12th weaving paths are 250-290mm; the yarn lengths of the yarns woven in the 1st, 2nd, 3rd, 4th, 7th, 8th, 9th, and 10th weaving paths are 200-230mm.

[0012] The basis weight of the fabric after it comes off the machine is 210±10 g / m². 2 Within the range.

[0013] The transverse loop density of the fabric is 19-21 W / cm, and the longitudinal loop density is 28-32 C / cm.

[0014] This utility model has the following beneficial effects:

[0015] 1. Based on a unique structural design and polyester ply elastic yarn raw material, this utility model produces a waffle fabric with a clear and regular texture, strong three-dimensional effect, fluffy and breathable, tough and durable, wrinkle-resistant and quick-drying, and also has stable elasticity. It can effectively restore its original shape after being stretched and maintain its elasticity during long-term use.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] This utility model discloses a 100% polyester mechanical elastic waffle fabric. The waffle fabric is woven using a high-density fine needle double-sided weft knitting circular knitting machine. The upper needle plate and lower needle cylinder of the circular knitting machine are knitted into a weft knitted structure, and the fabric surface has a raised waffle texture.

[0023] Specifically, the brand of the double-sided weft knitting circular knitting machine is Santoni ORION, the gauge is 28 needles / 25.4mm, the bobbin diameter is 864mm, the number of channels is 72F, and the machine speed is 16 r / min. For example... Figure 1 As shown, both the upper and lower needle plates of the double-sided weft knitting circular knitting machine adopt a 4-needle-4-needle arrangement for arranging and drawing needles. The needle arrangement and drawing of the upper and lower needle plates are complementary, that is, the empty needle positions of the upper needle plate and the lower needle cylinder are staggered.

[0024] like Figure 2 , 3 As shown, the fabric weaving pattern uses 8 warp rows and 12 rows as the smallest repeating unit. Among them, the 1st, 2nd, 3rd and 4th warp rows have the same structure and are formed by corresponding needle cylinder needles, while the 5th, 6th, 7th and 8th warp rows have the same structure and are formed by corresponding needle plate needles.

[0025] In the structural units of columns 1, 2, 3, and 4, rows 1, 2, 3, and 4 are knit stitch loop units, and rows 5, 6, 7, 8, 9, 10, 11, and 12 are knit stitch round units. In the structural units of columns 5, 6, 7, and 8, rows 1, 2, 3, 4, 5, 6, 11, and 12 are all purl stitch round units, and rows 7, 8, 9, and 10 are all purl stitch loop units. After repeated knitting, a clear and regular waffle pattern can be formed.

[0026] The fabric is woven from plied elastic yarn. During weaving, each weaving yarn is a plied elastic yarn of polyester stretch textured yarn. Specifically, the yarn lengths of the 5th, 6th, 11th, and 12th weaving rows are longer than those of the 1st, 2nd, 3rd, 4th, 7th, 8th, 9th, and 10th weaving rows. This utilizes the tension difference between the longer and shorter yarns to adjust and control the fabric so that the shorter yarns of the 1st, 2nd, 3rd, 4th, 7th, 8th, 9th, and 10th weaving rows form the base support structure of the fabric, while the longer yarns of the 5th, 6th, 11th, and 12th weaving rows create a floating effect. This combination achieves the precise construction of the waffle-patterned, three-dimensional texture, enhancing the fabric's texture and breathability. In this embodiment, the yarn length of the yarns woven in the 5th, 6th, 11th and 12th rows is 250-290mm, preferably 290mm; the yarn length of the yarns woven in the 1st, 2nd, 3rd, 4th, 7th, 8th, 9th and 10th rows is 200-230mm, preferably 230mm.

[0027] The weight of the greige fabric after finishing the waffle fabric is controlled at 210±10g / m². 2 Within this range, the transverse loop density of the finished fabric is 19-21 W / cm, and the longitudinal loop density is 28-32 C / cm.

[0028] Based on the material properties of polyester plied elastic yarn, this waffle fabric boasts numerous advantages, including durability, wrinkle resistance, quick-drying and easy care, and excellent colorfastness. Thanks to its unique weave structure and raw material selection, this waffle fabric also features a clear and regular texture, a strong three-dimensional visual effect, a fluffy and breathable porous structure, and stable elasticity. It effectively recovers its original shape after being stretched and maintains a certain degree of elasticity during long-term use, reducing fatigue.

[0029] In this embodiment, the twisted elastic yarn is a high-elasticity yarn processed from polyester stretch textured yarn, possessing excellent elasticity and resilience. The twisted elastic yarn has a specification of DTY 139Dtex / 108F, and each twisted elastic yarn contains numerous highly refined monofilaments, which can give the fabric a delicate cotton-like feel, providing a soft and skin-friendly experience. While possessing excellent elasticity and resilience, it also ensures comfort during wear or use. Preferably, this twisted elastic yarn is made by twisting high-elasticity polyester yarn and ordinary polyester yarn, wherein the specification of the high-elasticity polyester yarn is 50D / 36F, and the specification of the ordinary polyester yarn is 75D / 72F.

[0030] In summary, compared to traditional waffle fabrics, this all-polyester mechanical stretch waffle fabric possesses superior elasticity, resilience, breathability, and many other functional characteristics.

[0031] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims are within the scope of protection of the present invention.
