Abstract
Description
Technical Field
[0001] This utility model relates to the field of knitting weft knitting, and in particular to a solution-dyed fiber fleece knitted fabric and garment. Background Technology
[0002] With economic development and improved living standards, people have increasingly higher demands for clothing, paying more attention to fabrics. Besides fashion, comfort, affordability, and multifunctionality, consumers are also increasingly concerned about the environmental friendliness and healthiness of raw materials, including whether the raw materials and production processes are environmentally friendly. Currently, most sportswear and yoga wear on the market are made of filament fabrics. However, filament fabrics typically require dyeing in vats, resulting in wastewater, exhaust gas, and solid waste emissions. Furthermore, the high temperatures required for dyeing can harden the fibers, negatively impacting the fabric's feel. Therefore, there is a need for a solution-dyed fiber fleece knitted fabric that can solve these problems. Utility Model Content
[0003] The purpose of this invention is to provide a solution-dyed fiber fleece knitted fabric that can reduce pollution during the production process, and the fabric surface has a rich fleece texture, permanent color retention, good elasticity and comfort.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a solution-dyed fiber fleece knitted fabric, the fabric being woven from solution-dyed polyester fiber and solution-dyed spandex, including a minimum pattern repeat on the front side, the minimum pattern repeat structural unit including 2 rows of longitudinal loops and 2 rows of transverse loops, the upper needle plate and lower needle cylinder of the first and second rows are both arranged with alternating loop triangles and floating triangles, the yarns of the first and second rows are both solution-dyed polyester fiber and solution-dyed spandex, the solution-dyed polyester fiber is selected from solution-dyed polyester fiber or solution-dyed nylon fiber.
[0005] Furthermore, the fabric is arranged in two rows as one return position, wherein the upper needle plate of the first row and the lower needle cylinder of the second row are arranged in a looped triangle and a floating triangle, and the lower needle cylinder of the first row and the upper needle plate of the second row are arranged in a floating triangle and a looped triangle.
[0006] Furthermore, the fabric is formed by double-sided circular knitting machine, wherein the upper needle plate needles on the double-sided circular knitting machine are arranged in an ABAB cycle from left to right, and the lower needle cylinder needles are arranged in a BABA cycle from left to right.
[0007] Furthermore, the yarn materials of the first and second paths are 50-150D / 30-100F solution-dyed polyester fiber and 55-140D solution-dyed spandex.
[0008] Furthermore, the length of the solution-dyed polyester fiber yarn in the 100-needle configuration is 15-45cm, and the length of the solution-dyed spandex yarn in the 100-needle configuration is 5-20cm.
[0009] Furthermore, the garment includes the aforementioned solution-dyed fiber fleece knitted fabric.
[0010] The beneficial effects of this utility model are as follows: Compared with the prior art, the solution-dyed fiber fleece knitted fabric provided in this application is produced by using a double-sided circular knitting machine, through the arrangement and combination of machine parts (triangles and needles), combined with solution-dyed polyester fibers, solution-dyed spandex, and adjusted yarn length. The fabric's permanent color retention is mainly achieved by adding pigment during the spinning process, allowing the color to be encapsulated within the fibers, thus ensuring that the color will not fade. Furthermore, this combination not only gives the fabric excellent softness and comfort, but also, due to the bulkiness and high resilience of the solution-dyed polyester filaments and the elasticity of the solution-dyed spandex, the final fabric, in addition to its rich, fluffy, soft, and comfortable surface, also possesses elasticity. Attached Figure Description
[0011] Figure 1 This is a schematic diagram of the fabric structure of this utility model. Detailed Implementation
[0012] The present invention will be further described below with reference to the accompanying drawings.
[0013] Please see Figure 1 As shown, this utility model provides an embodiment: a solution-dyed fiber fleece knitted fabric, the fabric being woven from solution-dyed polyester fiber and solution-dyed spandex, including a minimum pattern repeat on the front side. The minimum pattern repeat structural unit includes two rows of longitudinal loops and two rows of transverse loops. The upper needle plate and lower needle cylinder of the first and second rows are arranged with alternating loop triangles and floating triangles. The yarns of the first and second rows are both solution-dyed polyester fiber and solution-dyed spandex. The solution-dyed polyester fiber is selected from solution-dyed polyester fiber or solution-dyed nylon fiber. The fabric of this utility model is woven from dyed fibers, the dyed fibers being a blend of polyester or nylon and spandex, with a polyester or nylon content of 82% and a spandex content of 18%. Solution-dyed fibers are produced by adding pigment during the spinning process, so that the color is encapsulated inside the fiber to achieve the purpose of not fading. Due to the fluffiness and high resilience of solution-dyed polyester filaments, as well as the elasticity of solution-dyed spandex, the final fabric not only has a rich, plush, soft, and comfortable surface, but also possesses elasticity.
[0014] Please continue reading. Figure 1As shown, in this embodiment, the fabric is woven in two rows. The upper needle plate of the first row and the lower needle cylinder of the second row are arranged in a loop-forming triangle and a floating triangle configuration, while the lower needle cylinder of the first row and the upper needle plate of the second row are arranged in a floating triangle and a loop-forming triangle configuration. By using different needles and triangle arrangements, the resulting fabric exhibits permanent color retention, good elasticity, a soft hand feel, and comfortable fit against the skin.
[0015] Please continue reading. Figure 1 As shown, in this embodiment, the fabric is formed by double-sided circular knitting machine. The upper needle plate needles on the double-sided circular knitting machine are arranged in an ABAB cycle from left to right, and the lower needle cylinder needles are arranged in a BABA cycle from left to right, with double-sided needle positions.
[0016] Please continue reading. Figure 1 As shown, in this embodiment, the yarn materials of the first and second yarns are 50-150D / 30-100F solution-dyed polyester fiber and 55-140D solution-dyed spandex. More specifically, the yarn materials of the first and second yarns are 75D / 48F solution-dyed polyester fiber or nylon fiber and 70D solution-dyed spandex. The length of the 100-gauge solution-dyed polyester fiber yarn is 15-45cm, and the length of the 100-gauge solution-dyed spandex yarn is 5-20cm. More specifically, the length of the 100-gauge solution-dyed polyester fiber or nylon fiber yarn is 30cm, and the length of the 100-gauge solution-dyed spandex yarn is 10cm.
[0017] like Figure 1 As shown, yarn H forms a solution-dyed fiber fleece knitted fabric under the action of needle G. The fabric returns in two directions, with the first direction receiving solution-dyed polyester filament and solution-dyed spandex, and the second direction receiving solution-dyed polyester filament and solution-dyed spandex.
[0018] Please continue reading.
