Description

KNITTING METHOD FOR PRODUCTION OF MOISTURE ABSORBENT QUICK-DRYING SINGLE-KNITTED FABRICFIELD OF THE INVENTION

[0001] The present disclosure relates to a knitting method for production of moisture absorbent quick-drying single-knitted fabric. Particularly, the present invention has excellent absorbency, moisture permeability and good drying property that far exceed national standards. BACKGROUND OF THE INVENTION

[0002] With the continuous improvement of living standards, the requirement of people on wearing comfort is higher and higher, and the common water-absorbing quick-drying product can not meet the requirements of people. Particularly, a large amount of sweat is generated by a human body during sports, and if the sweat cannot be absorbed and discharged timely and completely, the sweat can cause the fabric to be wet and adhered to the skin, so that the discomfort is particularly serious,

[0003] Typically, clothing, considered as a second skin plays a crucial role in providing wearer comfort irrespective of the changing environmental conditions. It should serve as a medium for moisture vapour and liquid moisture transfer. There are several techniques have been developed to render a fabric with moisture transfer property. These include fibres shape or diameter, blended yam, knitting technique, chemical treatment.

[0004] In one form of known prior art, the fabrics are treated with hydrophilic auxiliary agent in finishing stage. The auxiliary agents are attached on the surface of the fabric to allow quick moisture transport and evaporation. However, this function can be degraded and even disappeared after multiple wearing and washing. The use of chemicals in manufacturing process can also lead to ecological effects Therefore, it isnecessary to develop fabric with good absorbency, quick-dry along with breathability without adding a chemical auxiliary agent.

[0005] When the body is sweating, ordinary clothes can stick to the skin, and sweat can not be discharged in time, which can not meet people's requirements for health and comfort. Therefore, the moisture wicking fabric developed in recent years has been favored by people for wearing comfort, and the existing moisture Wicking fabric part is blended with temperaturecontrol yam and moisture wicking yam, and part of it The moisture wicking function auxiliary agents is added to the finishing of the fabric to make the fabric have the function of moisture absorption and perspiration. Both of these technical methods have certain defects, such as the high cost of weaving the functional yam blended fabric and the complicated finishing in the later stage. The fabric which is processed by the moisture wicking function auxiliary agents is not resistant to washing. Since the structure of the fabric is an important factor affecting the performance and style of the fabric. The auxiliary agents are attached on the surface of tine fabric to allow quick moisture transport and evaporation. However, this function can be degraded and even disappeared after multiple wearing and washing. The use of chemicals in manufacturing process can also lead to ecological effects.

[0006] Accordingly, the performance of the moisture wicking fabric is affected by the yam structure and the fabric structure and the like, in addition to the fiber type and the blending ratio of the fabric. Therefore, a knitted fabric having a single-guide wet function is popular because it can quickly guide moisture while ensuring a quick drying of the inner layer of the fabric.

[0007] At present people also study the water absorption and quick drying performance of the fabric more frequently. For example, chineese patent No. 112105771 discloses a single-sided knitted fabric. The knitted fabric isa single-side-weave weft knitting fabric and comprises a surface and an inner side, wherein the inner side is formed by alternately arranging hydrophobic yams (b) and hydrophilic yams (A) at intervals along weft coils, and a hydrophobic part is arranged on the inner side. The fabric has excellent water absorption quick-drying property and skin dry feeling. Taiwan patent application no. M485256 discloses a moisture wicking single-guide wet fabric structure comprising a moisture guiding layer, a diffusion layer and an evaporation layer, wherein the moisture guiding layer is an inner layer and has a pad structure, and is organized by the pad in direct contact with the surface of the human skin, the diffusion layer and the evaporation layer are disposed on tile outer layer of the moisture guiding layer, and are connected by a tuck, a loop, and a fabric structure connected to the pad structure of the moisture guiding layer. The disadvantage of this patented technology is that the chemical auxiliary agent is more difficult, and the outer layer has to be subjected to hydrophilic treatment in advance, which has a long process flow, high interlacing cost, and is not resistant to water washing after hydrophilic finishing.

[0008] Hence, the rising living standards have changed people’s needs including expectations of clothing and textile products. In particular, the fabric is used either for casual or sports apparels should have excellent moisture transfer property to keep the microclimate of the body and clothing cool, dry and comfortable. Also, the excellent moisture transfer property explaining the moisture is required to be transferred rapidly from one side of tiie fabric to the other and then to be spread over a wide surface area to maximize comfortability effect due to evaporation. Such fabric is also drying faster than normal fabrics.

[0009] Consequently, in order to solve the technical problems, the invention aims to provide a moisture absorbent quick-drying fabric knitted fabric. The fabric developed by the production method exhibits advantagesOf excellent absorbency, moisture permeability and good drying property that far exceeds national standards.SUMMARY OF THE INVENTION
