Embodiment 1

[0031] 1. Preparation of PVA / SA spinning solution

[0032] Dissolve 10 g of PVA in 90 g of deionized water, swell at room temperature for 12 h, mechanically stir at 90° C. for 3 h, and cool to room temperature to obtain a 10 wt % PVA solution. 3g of SA was dissolved in 97g of deionized water at 60°C for 3h to obtain a 3wt% SA solution. Then mechanically stirred, the PVA and SA solutions were mixed at 9:1 (v / v), and SDS (0.1115g / 50mL) surfactant was added to obtain an electrospinning solution.

[0033] 2. Preparation of Pretreated Fabrics

[0034] The polyester fabric was cut into 40cm×17cm, the thickness of polyester was 60μm, and the polyester was treated with 10wt% CaCl 2 Soak in the solution for 20 minutes, suspend until there is no droplet, and then fix it on the rotating collector of the electrospinning machine. The rotational speed of the collector was 100 rpm.

[0035] 3. Preparation of Unidirectional Moisture-permeable Fabric

[0036]The electrospinning solution w...

Embodiment 2

[0038] Same as Example 1, the difference is that CaCl 2 The solution concentration is 5 wt%.

Embodiment 3

[0040] Same as Example 1, the difference is that CaCl 2 The solution concentration is 15 wt%.

Abstract

The invention provides a fabric with good unidirectional moisture conductivity and a preparation method thereof. The preparation method comprises the following steps that firstly, a fabric base material is pretreated by a calcium salt solution; then fibers are formed by using a polyvinyl alcohol/sodium alginate solution through an electrostatic spinning method and deposited on a single surface ofthe fabric; a polyvinyl alcohol/calcium alginate gel layer is formed on the surface of the fabric in situ by using polyvinyl alcohol/sodium alginate; and the spinning layer is further cross-linked byusing a crosslinking agent, a cross-linked polyvinyl alcohol/calcium alginate (PVA/SA) functional layer is formed, and the unidirectional moisture-conducting fabric is obtained. By means of the treatment mode, the unidirectional moisture-conducting fabric can be obtained, and the obtained fabric has good air permeability and antistatic performance. The unidirectional moisture-conducting fabric canbe used for manufacturing clothes, outdoor jackets, masks, shoes, hats, medical supplies and the like, and the obtained product has the effects of discharging internal sweat and balancing internal and external humidity; and meanwhile, the unidirectional moisture-conducting fabric has good air permeability and antistatic performance, and the wearing comfort of the clothes can be improved.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a unidirectional moisture-permeable fabric and a preparation method thereof. Background technique [0002] One-way conduction phenomena widely exist in nature, such as plant nerve conduction, water and energy transmission, etc. Through the bionic design, one-way conduction effectively solves many practical problems such as oil-water separation, mist collection and water collection in the process of separation or collection. In recent years, people have put forward higher requirements for the comfort and functionality of clothing, and multi-functional textiles such as waterproof and moisture-permeable, moisture-absorbing and quick-drying, heat-conducting and cool-feeling have received extensive attention. Unlike cotton fabrics, unidirectional moisture-wicking fabrics can quickly guide sweat away from the human body, keeping the skin dry and comfortable. The fabric based on do...
