Description

Technical Field

[0001] The invention relates to the technical field of textile fabrics, and in particular to an antibacterial, moisture-absorbing and breathable knitted fabric and a preparation method thereof. Background Art

[0002] Fabric is the material used to make clothing. As one of the three elements of clothing, fabric can not only interpret the style and characteristics of clothing, but also directly influence the color and shape of clothing. In the world of clothing, clothing fabrics are varied and changing with each passing day. But generally speaking, high-quality and high-end fabrics are mostly comfortable to wear, sweat-absorbent and breathable, drape straight, visually noble, and soft to the touch.

[0003] In summer, for people who sweat easily, if the fabric is not breathable enough and has poor moisture absorption and quick-drying properties, the fabric will easily stick to the skin, resulting in poor wearing comfort. In addition, the antibacterial effect of general fabrics is poor, which will lead to the growth of bacteria inside when worn, thus affecting physical health.

[0004] The prior art with publication number CN214266841U discloses an antibacterial, breathable and moisture-conducting fabric, comprising a moisture-conducting layer, an antibacterial layer, a spandex core-spun yarn layer, a banana fiber layer and an inner layer, wherein a waterproof and breathable layer is bonded to the top of the moisture-conducting layer, the bottom of the moisture-conducting layer is compositely connected to the top of the antibacterial layer, the bottom of the antibacterial layer is compositely connected to the spandex core-spun yarn layer, the bottom of the spandex core-spun yarn layer is compositely connected to the top of the banana fiber layer, a plurality of air holes are arranged between the antibacterial layer and the spandex core-spun yarn layer, the top and bottom of the air holes respectively penetrate the antibacterial layer and the spandex core-spun yarn layer, and the bottom of the banana fiber layer is compositely connected to the inner layer; the prior art has the following problems: the fabric has many layers, the fabric is relatively thick, and the fabric has poor air permeability, antibacterial property and quick-drying property. Summary of the invention

[0005] In view of this, the present invention aims to provide an antibacterial, moisture-absorbing and breathable knitted fabric and a preparation method thereof, so as to solve the problems in the prior art that the fabric has many layers, is relatively thick, and has poor air permeability, antibacterial property and quick-drying property.

[0006] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0007] An antibacterial, moisture-absorbing and breathable knitted fabric, the knitted fabric is knitted by an upper needle disc of two needles and a lower needle cylinder of two needles, and is knitted in a cycle of 12 routes, wherein the organization structure of the knitted fabric is arranged in the following order:

[0008] The needle discs and lower needle cylinders on the first, second, seventh and eighth routes are all in loop formation;

[0009] On the third route, the low heel needle of the needle disc is a tuck stitch, the high heel needle of the upper needle disc and the low heel needle of the lower needle cylinder are a floating stitch, and the high heel needle of the lower needle cylinder is a loop stitch.

[0024] Furthermore, the thickness of the polyester filament is 20-50D, and the F number of the polyester filament is 12-24F.

[0025] This setting not only makes the fabric have better elasticity, breathability and quick-drying properties, but also makes the fabric have better anti-pilling properties.

[0026] Furthermore, the coil lengths of the first, second, fourth, sixth, seventh, eighth, tenth and twelfth loops are 13-15 cm / 50 stitches.

[0027] This setting must ensure the tightness of the fabric while also making the fabric breathable and quick-drying.

[0028] Furthermore, the coil lengths of the third, fifth, ninth and eleventh loops are 6 to 8 cm / 50 stitches.

[0029] This setting must ensure the tightness of the fabric while also making the fabric breathable and quick-drying.

[0030] Furthermore, the knitted fabric has a gram weight of 135 to 140 g / m2.

[0031] A method for preparing an antibacterial, moisture-absorbing and breathable knitted fabric, used to prepare the above-mentioned fabric, comprises the following steps:

[0032] S1, yarn count preparation;

[0033] S2, fabric weaving;

[0034] S3, open width washing;

[0039] Furthermore, in step S5, it also includes:

[0040] S51, pre-processing;

[0041] S52, staining;

[0042] S53, post-staining treatment.

[0043] Furthermore, the process parameters of step S3 are a temperature of 30 to 50° C. and a time of 15 to 30 min.

[0044] This setting can increase the weight of the fabric on the one hand to prevent the fabric from being too thin and light, and on the other hand, it can pre-shrink the fabric to improve its stability.

[0045] Compared with the prior art, the antibacterial, moisture-absorbing and breathable knitted fabric and the preparation method thereof described in the present invention have the following advantages:

[0046] 1) The 12-way braided structure of the present invention is woven into a single-sided fabric, making the fabric lighter, thinner and more breathable, with better wearing comfort and quick-drying performance;

[0047] 2) The present invention weaves the first banana fiber, the second banana fiber and the polyester filament, which not only improves the antibacterial property of the fabric, but also improves the quick-drying property of the fabric.
