Abstract

The present invention relates to a fast-conducting and fast-drying microporous fine-pile polyester fabric and a preparation method thereof. The fabric comprises three layers from top to bottom: a fluff layer, an intermediate layer and an inner layer. The intermediate layer and the inner layer adopt a double-sided weft knitting process to form a jacquard structure. The intermediate layer and the inner layer are woven by two polyester yarns, A yarn and B yarn. The intermediate layer contains A yarn and B yarn, and the inner layer is all B yarn. The fluff layer is the intermediate layer of the fabric prepared by a sanding finishing process. The present invention is a microporous fine-pile polyester knitted fabric with a three-layer effect prepared by a reasonable configuration of two different yarns, a change design of the jacquard structure, and a sanding finishing process. After the human body sweats, the sweat can be spontaneously transferred from the inside of the fabric to the fluff layer, forming an excellent multi-layer gradient fabric differential capillary effect. The sweat can be quickly unidirectionally conducted and evaporated, so that the fabric has good air permeability, fast-conducting and fast-drying functions.

Description

Technical Field

[0001] The invention belongs to the technical field of textile preparation, and in particular relates to a fast-conducting and fast-drying microporous fine-pile polyester fabric and a preparation method thereof. Background Art

[0002] With the continuous improvement of people's living standards and the continuous enhancement of textile technology, people's requirements for the comfort of clothing fabrics are also increasing. In a hot environment or when people are exercising, a large amount of sweat will be discharged from the surface of the human skin. If this sweat cannot be quickly transferred to the outer surface of the clothing and evaporate quickly, the human body will feel uncomfortable. Therefore, for clothing fabrics that are worn next to the body, it has become an important requirement to have excellent quick-drying function and good hand comfort.

[0003] At present, there are many studies on unidirectional moisture conduction and quick-drying functional fabrics. For example, the patent CN108330601A discloses a moisture-absorbing quick-drying knitted fabric and its preparation method, which uses moisture-absorbing quick-drying fiber, modal fiber, and combed cotton blended into yarn, uses a weft knitting circular machine to weave knitted cotton wool cloth, and uses a moisture-absorbing quick-drying finishing agent, a cross-linking agent and a finishing agent made of water to post-finish the cotton wool cloth. Although the fabric prepared by this method can achieve a good moisture-absorbing quick-drying effect, the use of the finishing agent is not conducive to the stability and durability of the function. The Chinese patent CN101962885A discloses a method for preparing a product with a unidirectional moisture conduction function, after the prepared fabric is hydrophilized, a working liquid containing a water-repellent finishing agent is used to spray one side of the fabric, so that the fabric has a unidirectional moisture conduction function. Although this method can make the fabric achieve a unidirectional moisture conduction effect and saves the environment, the process is relatively complicated. Although many studies similar to the above have also enabled fabrics to achieve good quick-conducting and quick-drying functional requirements, the common problem is that the fabric itself does not have a spontaneous and excellent wicking gradient while having good hand comfort. However, in the prior art, the double-layer structure fabric made of ultrafine fibers and ordinary fibers woven through a reasonable process has a good wicking gradient. If the fabric is further sanded on this basis, the presence of the sanded layer can not only improve the wicking gradient of the fabric, making the moisture conduction and evaporation faster, but also increase the hand comfort of the fabric. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the functionality of existing one-way moisture-conducting and quick-drying functional fabrics is not durable and the effect is not good. A quick-conducting and quick-drying microporous fine-pile polyester fabric and a preparation method thereof are provided. The prepared fabric has a comfortable hand feel and a durable quick-conducting and quick-drying function.

[0005] The present invention adopts the following technical scheme: a fast-conducting and quick-drying microporous fine-pile polyester fabric, which includes a fluff layer, an intermediate layer and an inner layer from top to bottom, the intermediate layer and the inner layer adopt a double-sided weft knitting process to form a jacquard structure, the intermediate layer and the inner layer are woven by two polyester yarns A yarn and B yarn, the intermediate layer contains A yarn and B yarn, the inner layer is all B yarn, and the fluff layer is prepared by the intermediate layer of the fabric through a sanding finishing process.

[0006] Furthermore, the minimum weave cycle height of the fabric is 24, and the minimum weave width is 4.

[0007] Furthermore, the A yarn and the B yarn have different fiber finenesses.

[0008] Furthermore, the A yarn is ultrafine polyester DTY, and the B yarn is ordinary polyester DTY.

[0009] Furthermore, the fabric is woven by a multi-needle track double-sided circular weft knitting machine, and the multi-needle track double-sided circular weft knitting machine includes cylinder needles of 4 knitting needle tracks and dial needles of 2 knitting needle tracks.

[0010] Furthermore, the cylinder needles of the four knitting needle tracks are A, B, C, and D respectively, and the dial needles of the two knitting needle tracks are a and b respectively.

[0011] Furthermore, the fabric is woven in a loop from the 1st to the 24th route, the A yarn is inserted into the even-numbered routes, the B yarn is inserted into the odd-numbered routes, the yarns in the 12 routes through which the A yarn is inserted are woven only on the cylinder needles and not on the dial needles; part of the yarns in the 12 routes through which the B yarn is inserted are woven only on the dial needles, and the remaining yarns are woven on both the dial needles and the cylinder needles at the same time.

[0012] The method for preparing a quick-conducting and quick-drying microporous fine-pile polyester fabric, the fabric is composed of a plurality of tissue cycles, each tissue cycle is woven from the 1st to the 24th cycle, and includes the following steps:

[0013] Insert yarn A into the 2nd, 4th, 6th, 8th, 10th, 12th, 14th, 16th, 18th, 20th, 22nd and 24th threads, a total of 12 even-numbered threads. Yarn A is only knitted on the cylinder needles and not on the dial needles.

[0014] Insert the B yarn into the 1st, 3rd, 5th, 7th, 9th, 11th, 13th, 15th, 17th, 19th, 21st and 23rd routes, a total of 12 odd routes, wherein some of the B yarns are knitted only on the dial needles, and the remaining B yarns are knitted on the dial needles and the cylinder needles at the same time, and the A yarn and the B yarn are knitted to form the middle layer and the inner layer of the fabric;

[0015] The middle layer of the fabric is subjected to a sanding finishing process, where the middle layer of the fabric is slowly rubbed by the sandpaper roller of a running sanding machine under a certain tension, so that a layer of uniform and fine short fluff is formed on the middle layer of the fabric to obtain the fluff layer of the fabric.

[0016] Furthermore, the speed of the sanding roller of the sanding machine is 800r / min, and the fabric running speed is 10m / min.

[0017] Furthermore, the fabric maintains a tension of 0.4 MPa when rubbed by the sandpaper roller.

[0020] (2) The fabric designed by the present invention has two kinds of yarns, A and B, in the middle layer, and the inner layer of the fabric is all B yarn. The different fiber fineness of the two yarns results in a good differential capillary effect between the two layers, which can achieve the fabric's breathability and rapid unidirectional moisture conduction.

[0021] (3) The three-layer structure of the fabric designed by the present invention has an excellent wicking gradient, so that sweat can be spontaneously transferred from the inner layer to the fluff layer in one direction, and evaporate quickly on the fluff layer, so that the fabric can achieve the function of quick conduction and quick drying;

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Example 1

[0035] A fast-conducting, fast-drying microporous fine-pile polyester fabric, which is woven from two different fiber finenesses of 84D / 384F ultrafine polyester DTY (A yarn) and 50D / 24F ordinary polyester DTY (B yarn) on a multi-needle double-sided circular weft knitting machine with a jacquard structure. The fabric has a minimum weave cycle height of 24 and a width of 4.

[0036] The multi-needle track includes 4 needle tracks of cylinder needles A, B, C, D and 2 needle tracks of needle disk needles a and b. The needle arrangement diagram is as follows: Figure 2 shown.

[0037] Fabric weaving process diagram Figure 3 As shown, the triangular configuration diagram of the fabric is as follows Figure 4 shown.

[0038] The fabric is composed of several weave loops, each of which is woven from the 1st to the 24th loops, among which A yarn is inserted into the even-numbered loops, and B yarn is inserted into the odd-numbered loops. The yarn in the 12 loops that insert A yarn is only woven on the cylinder needles and not on the dial needles. Some of the yarn in the 12 loops that insert B yarn is only woven on the dial needles, and the rest of the yarn is woven on the dial needles and cylinder needles at the same time. The middle layer (front side) of the fabric contains A yarn and B yarn, and the inner layer (back side) of the fabric is all B yarn.

[0039] Specific weaving process of quick-drying microporous fine fleece polyester fabric:

[0040] Wear yarn B on the 1st and 19th loops, knit tucks on cylinder needle A, and knits loops on dial needles a and b;

[0041] Wear yarn A in the 2nd and 20th loops, knit on cylinder needles A, C, and D, tuck on B, and do not knit on the dial needles;

[0042] Wear yarn B on the 3rd and 21st loops, knit tucks on cylinder needle C, and knit loops on dial needles a and b;

The inner layer of the fabric is all 50D / 24F ordinary polyester DTY (B yarn). This combination of yarns forms thicker capillaries in the inner layer of the fabric and thinner capillaries in the middle layer. A strong differential capillary effect is formed between the two interfaces of the fabric, guiding sweat 4 to flow spontaneously from the inner layer 1 to the middle layer 2, thereby realizing the rapid unidirectional moisture conduction function of the fabric. The fabric is subjected to a sanding finishing process, in which the middle layer of the fabric is slowly rubbed by the sandpaper roller of a running sanding machine under a tension of 0.4 MPa. The speed of the sandpaper roller of the sanding machine is 800 r / min, and the running speed of the fabric is controlled at 10 m / min, so that a layer of uniform and fine short fluff is formed on the surface of the fabric, so that the fabric becomes a three-layer structure fabric including an inner layer 1, a middle layer 2 and a fluff layer 3. There is an excellent wicking gradient between the three-layer structure, so that sweat 4 can be spontaneously transferred from the inner layer 1 to the fluff layer 3 through the middle layer 2 in one direction, and quickly evaporates by attaching to the fluff layer 3, so that the fabric has quick-conducting and quick-drying functions.
