Problems solved by technology

For example, for the method of treating the finished fabric to have unidirectional moisture transfer performance, the single-sided liquid supply path used in it is realized by the screen printing method, which requires high technical requirements. , The size of the droplet is limited by the printing mesh processing technology, the size of the water-repellent area is too large, it is difficult to form small-sized capillary channels, and the suction effect on water (sweat) is less obvious

Embodiment 1

[0029] Ramie / cotton 50 / 50 knitted fabric, pineapple texture, weighing 180g per square meter, using conventional scouring, bleaching and mercerizing processing, and rolling the Queenset PSO-5500 produced by Japan Kotani Chemical Industry Co., Ltd. before the fabric enters the setting machine. Durable and hydrophilic Agent. The amount of the hydrophilic agent is 30g / L, and the rolling-over rate is 80%. It is shaped in a shaping machine at a shaping temperature of 180°C for 60 seconds, which is a POWER-LINE stenter shaping machine produced by Bruckner, Germany. This fixed machine is equipped with a rotary nozzle spray device on the side of the machine head. The fabric passes through the spray device at a speed of 30m / min. The spray is transferred to spray the working fluid of the fluorine-containing water-repellent finishing agent to the fabric passing under the side. Shower. The fluorine-containing water-repellent finishing agent is Oleophobol CP-S, a non-ionic fluorine-contain...

Embodiment 2

[0031] Pure polyester knitted fabric, 100dtex polyester DTY, 160g / m with double knitting machine 2 After the conventional scouring process is used to remove oil stains, the fabric is hydrophilized with PermaloseTM hydrophilic agent (polyether ester structure) produced by ICI in the United Kingdom before entering the setting machine, which accounts for the total weight of the fabric 5%, immersion temperature 80℃, time 20min. The pH of the immersion liquid is 5, and the bath ratio is 25:1. Bake for 100s in the Korea Nissin 3200 setting machine at 180℃. Then place the treated fabric on the fabric conveying device of the spray device, and use a pressure nozzle to apply the non-ionic fluorine-containing water-repellent finishing agent Oleophobol CP-S produced by Huntsman at a pressure of 0.8kg. The concentration is 40g / L Working fluid 1.5ml / m 2 Afterwards, it is baked at 180°C (three-stage oven), and the fabric obtained after the above treatment is passed under the door frame with ...

Embodiment 3

[0034] The following method was used to evaluate the unidirectional moisture conductivity of the obtained fabric.

[0035] Evaluation method 1: Determine the unidirectional moisture conductivity of the fabric by comparing the area of ​​residual water marks on the fabric.

[0036] A syringe with a larger needle or a pipette with a smaller caliber is used to generate droplets of smaller size to simulate sweat droplets, which are respectively added to the fabrics of Example 1 and Example 2 made of fluorine-containing water-repellent finishing agent The side treated with the working fluid and the side not treated with the working fluid of the fluorine-containing water-repellent finishing agent. When the droplets are dripped onto one side of the fabric treated with the working fluid of the fluorine-containing water-repellent finishing agent, visually the droplets quickly penetrate into the other side of the fabric and remain in the working fluid treated with the fluorine-containing wate...

Abstract

The invention relates to a knitted fabric with a one-way moisture guiding function. The knitted fabric is characterized in that water repellent areas distributed irregularly are arranged on any side of the knitted fabric, the areas of the water repellent areas are in a range of 0.01mm2 to 4mm2, and the distance among one another is between 0.1mm and 2mm. Particularly, the water repellent areas on any side of the knitted fabric are basically circular and different in size. 'Two side structures' different in hydrophilia and hydrophobicity are constructed on the two sides of the fabric, the water repellent areas on the side with hydrophobicity are smaller, and the structure is simpler.

Description

[0001] This application is a divisional application of a Chinese patent application with an application number of 201010292743.2, an application date of September 20, 2010, and an invention title of "Knitted Fabric with One-way Wetting Function". Technical field [0002] The invention relates to a fabric with a unidirectional moisture-conducting function. In particular, the present invention relates to a knitted fabric having unidirectional moisture conductivity. Background technique [0003] In recent years, with the development of the clothing industry, people have not only limited their attention to clothing styles, but also focused more on the research and improvement of clothing fabrics that can bring comfort to the human body. In particular, in order to be able to provide the human body with a comfortable and convenient feeling effect for a longer time, people are becoming more and more demanding on the choice of clothing fabrics and the functional requirements of the fabric...
