Description

Technical Field

[0001] This invention relates to the textile field, and in particular to a single-sided jacquard knitted fabric and its manufacturing method. Background Technology

[0002] Knitted fabrics are soft, moisture-wicking, breathable, and warm, and most also possess excellent elasticity and stretch. Knitted garments are comfortable, form-fitting, and unrestricted, fully showcasing the body's curves. Among them, knitted jacquard fabrics are also beautiful, environmentally friendly, and comfortable, making them popular with consumers. However, as living standards improve, people's demands for clothing are also increasing. While most knitted jacquard fabrics on the market are sought after for their attractive appearance, they often lack functions like moisture wicking. Therefore, there is an urgent need in the market to use functional raw materials to create functional knitted jacquard fabrics for consumers to choose from. Summary of the Invention

[0003] The purpose of this invention is to provide a single-sided jacquard knitted fabric and its manufacturing method. The fabric is not only aesthetically pleasing, but also has moisture-wicking properties. Furthermore, the manufacturing process is simple, the weight reduction is uniform, and the fabric has better moisture absorption and wicking effects.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a single-sided jacquard knitted fabric, comprising a knitted fabric body, wherein the knitted fabric body is made of polyester-nylon interwoven filament and elastic spandex, knitted on a single-sided dense-needle open-width circular knitting machine according to a set needle arrangement and diamond arrangement, with 6 horizontal loops and 16 vertical loops as the pattern return, and 6 needles as one return. The 6 needles are arranged from left to right as grade 1 needles, grade 1 needles, grade 2 needles, grade 1 needles, grade 1 needles, and grade 3 needles. 16 loops constitute one return, and the diamond arrangement from top to bottom is as follows:

[0005] Route 1-3: Circular water chestnuts, circular water chestnuts, circular water chestnuts;

[0006] Routes 4-8: Water chestnuts in circles, water chestnuts clustered together, water chestnuts in circles;

[0007] Route 9-11: Circular water chestnuts, circular water chestnuts, circular water chestnuts;

[0008] Routes 12-16: Circular water chestnuts, Circular water chestnuts, Clustered water chestnuts.

[0009] Furthermore, the polyester-nylon interwoven filament consists of two types of microporous filaments, with finenesses of 45D and 70D respectively, and filament numbering of 36F and 48F respectively. The elastic spandex has a fineness of 30D.

[0010] A method for producing a single-sided jacquard knitted fabric includes a knitting process, an oil removal and pre-setting process, an alkali reduction process, a dyeing process, and a post-treatment process.

[0011] The weaving process is as follows: microporous filaments and elastic spandex are woven on a single-sided dense needle open-width circular knitting machine according to the set needle arrangement and diamond arrangement. The pattern return is formed by 6 horizontal loops and 16 vertical loops. 6 needles form one return and 16 vertical loops form one return, which is used to weave the greige fabric.

[0012] The degreasing and pre-forming process is as follows: after the fabric is woven, it is continuously washed with water to remove oil, and then pre-formed.

[0013] The alkali reduction treatment process is as follows: the pre-shaped fabric is fed into the dyeing vat, the main pump speed is 60%, the cloth roller speed is 35%, the liquor ratio is 1:10, the caustic soda flakes are diluted with room temperature water in the dyeing vat and then added to the dyeing vat, the temperature is raised to 65-75℃, the alkali reduction accelerator is added, the temperature is raised to 95-105℃ and kept for 40-60 minutes, the temperature is lowered to 70-80℃, the reduction rate is measured by taking a sample, the temperature is lowered to 60℃ and the overflow washing water is added for 5-10 minutes, glacial acetic acid is added, the temperature is raised to 60-65℃ and kept for 10-20 minutes for neutralization;

[0014] The dyeing process is: bottom-flow overflow cylinder dyeing;

[0015] The post-processing steps include adding absorbent and hydrophilic auxiliaries for post-processing, and finally shaping the finished product to obtain a single-sided jacquard knitted fabric.

[0016] Furthermore, after diluting the caustic soda flakes, the temperature is increased to 65-75°C at a rate of 1.5°C / min. After adding the alkali reduction accelerator, the temperature is increased to 95-105°C at a rate of 1.2°C / min and held for 40-60 minutes. Then, the temperature is decreased to 70-80°C at a rate of 1.2°C / min.

[0017] Furthermore, the content of the caustic soda flakes is 7 g / L, and the content of the alkali reduction accelerator is 2 g / L.

[0018] Furthermore, the content of the glacial acetic acid is 1 g / L.

[0019] Furthermore, the continuous flat-width water washing degreasing temperature is 80-95℃, and the machine speed is 10-30m / min; the predetermined temperature is 150-195℃, and the machine speed is 18-25m / min.

[0020] Furthermore, the staining temperature is 95–105°C, and the process lasts for 30–60 minutes.

[0021] Furthermore, the post-treatment temperature is 40-70℃, the operation time is 10-20 minutes, the final product setting temperature is 130-160℃, the machine speed is 18-40 m / min, and the content of the suction and hydrophilic additives is 1-3 g / L.

[0022] The beneficial effects of this invention: Unlike most jacquard textured knitted T-shirt fabrics on the market that lack functionality, the polyester-nylon interwoven filaments in this invention are microporous yarns with a porous cross-section after alkali reduction treatment. Using a single-sided dense needle open circular knitting machine with a weft knitting gauge of 32-36 needles × 34 inches, 6 needles and 12 different diamond-shaped arrangements, the microporous special yarns and elastic spandex are knitted into a jacquard textured single-sided fabric. The jacquard texture improves the appearance, and the differentiated knitting design, alkali reduction pretreatment, and hydrophilic absorbent and wicking agent posttreatment give the finished fabric moisture-wicking and perspiration-wicking functions.

The knitted fabric body uses 6 horizontal loops and 16 vertical loops for the pattern return. The knitted fabric body is made of polyester-nylon interwoven filaments and elastic spandex, woven on a single-sided dense-needle open-width circular knitting machine with a needle pitch of 32-36 gauges x 34 inches, according to a set needle arrangement and diamond pattern. The polyester-nylon interwoven filaments are microporous yarns with a porous cross-section after alkali reduction treatment.

[0054] Reference Figure 3 The weft direction consists of 6 loops, and the needles are arranged from left to right as follows: grade 1 needle, grade 1 needle, grade 2 needle, grade 1 needle, grade 1 needle, grade 3 needle, a total of 6 needles for 1 return.

[0055] Reference Figure 4 The 16-channel vertical coil is for return, and the diamond shape is arranged from top to bottom as follows:

[0056] Route 1-3: Circular water chestnuts, circular water chestnuts, circular water chestnuts;

[0057] Routes 4-8: Water chestnuts in circles, water chestnuts clustered together, water chestnuts in circles;

[0060] The first to the 16th feed simultaneously with polyester-nylon interwoven filaments, which are two types of microporous special filaments with a fineness of 45D and 70D, and a filament hole count of 36F and 48F. The elastic spandex is 30D and woven into a fabric.

[0061] The degreasing and pre-forming process is as follows: after the fabric is woven, it is continuously washed with water to remove oil, and then pre-formed.

[0062] Continuous flat-width water washing for oil removal: temperature 80-95℃, machine speed 10-30m / min

[0063] Pre-set type: Temperature 150-195℃, machine speed 18-25m / min

[0064] Alkali reduction treatment process:

[0065] Prepare caustic soda flakes: 7g / L

[0066] Alkali reduction accelerator: 2g / L

[0067] Glacial acetic acid: 1g / L

[0068] The pre-shaped fabric is fed into the dyeing vat. The main pump speed is 60%, the cloth roller speed is 35%, and the liquor ratio is 1:10. The caustic soda flakes are diluted with room temperature water and added to the dyeing vat. The temperature is raised to 70°C, and the alkali reduction accelerator is added. The temperature is raised to 100°C and kept for 60 minutes. The temperature is lowered to 75°C, and the weight loss rate is measured. The temperature is lowered to 60°C, and the overflow wash water is added for 3 minutes. Glacial acetic acid is added, and the temperature is raised to 65°C and kept for 10 minutes for neutralization.

[0074] Reference Figure 5 Its jacquard texture enhances its aesthetic appeal, while the differentiated weaving design, alkali reduction pretreatment, and hydrophilic absorbent finishing agent posttreatment give the finished fabric moisture-wicking properties.

[0075] The weight reduction process of this method is easy to control and operate for small-batch, multi-variety products. Once the weight reduction is complete on the same dyeing vat, the subsequent dyeing process can be completed. Compared with the traditional process, weight reduction and dyeing are carried out on different machines, which shortens the process flow and operation time, saves power costs, reduces the probability of abnormalities, and ensures uniform weight reduction in the dyeing vat with stable results, thereby improving the moisture absorption and perspiration performance of the fabric to a certain extent.
