TECHNICAL FIELD

[0001] The utility model relates to the field of textile technology, concretely relates to a waterproof and moisture-conducting double-sided different micro window printed fabric. BACKGROUND

[0002] At present, textile fabric has various styles, for example, soft fabric, lustrous fabric, thick fabric, transparent fabric and functional fabric, etc., and is usually divided into waterproof fabric and hydrophilic fabric according to hydrophobicity, however, the waterproof or hydrophilic fabric with single property cannot meet the requirements of people in actual application, that is, the inner side of the fabric contacting the skin requires easy perspiration, and the outer side of the fabric not contacting the skin requires waterproof and anti-fouling function.

[0003] Therefore, a waterproof and moisture-conducting double-sided different micro window printed fabric is needed to solve the above problems. UTILITY MODEL CONTENTS

[0004] The utility model discloses a waterproof and moisture-conducting double-sided different micro window printed fabric to solve the problem that the existing fabric is usually divided into waterproof fabric and hydrophilic fabric, and cannot meet the requirements of people in actual application, that is, the inner side of the fabric contacting the skin requires easy perspiration, and the outer side of the fabric not contacting the skin requires waterproof and anti-fouling function.

[0005] The technical scheme of the utility model is as follows:

[0006] A waterproof and moisture-conducting double-sided different micro window printed fabric, comprising a fabric, the outer surface of the fabric is printed with strong hydrophobic micro windows, and the inner surface is printed with weak hydrophilic micro windows, the fabric is hydrophilic high-count high-density fabric, the strong hydrophobic micro window comprises a plurality of strong hydrophobic units uniformly distributed along the horizontal direction and / or the vertical direction, and the strong hydrophobic unit comprises a large circle and a small circle coaxially arranged in the large circle.

[0007] Preferably, the diameter of the large circle is 700-900 μm, and the height is 400-500 μm.

[0008] Preferably, the diameter of the small circle is 300-500 μm, and the height is 300-400 μm.

[0009] Preferably, the printing line width of the large circle and the small circle is 300-400 μm.

[0010] Preferably, the weak hydrophilic micro window is a grid.

[0011] Preferably, the length and width of the unit cell of the grid are equal.

[0012] Preferably, the length and width of the unit cell is 4000-12000 μm, and the height is 100-300 μm.

[0013] Preferably, the printed line width of the unit cell is 450-550 μm.

[0014] Preferably, a thickening agent, a foaming agent and a resin are included in the printing paste.

[0015] Preferably, the printing paste further includes a waterproofing agent.

[0016] Compared with the prior art, the present application has the following beneficial effects:

[0017] 1) Novelty: On the same piece of fabric, the contradictory properties of waterproofing, hydrophilicity and moisture permeability are organically unified.

[0018] 2) Environmental protection: Compared with traditional coating finishing, the micro-window technology greatly reduces the amount of waterproofing agent used.

[0019] 3) Lightness: The discontinuous and trace amount application of the high-molecular additive on the fabric effectively maintains the soft hand feeling and good mechanical properties of the fabric, which is particularly important for outdoor equipment and light-weight fabrics.

[0020] 4) Flexibility: On the same piece of fabric, the functional areas (shoulders, back) can be customized and personalized according to the needs and specific application environment, making the product more targeted.

[0021] 5) Efficiency: When water droplets fall on the fabric, the strong hydrophobic micro-windows can hold the water droplets in a ring-shaped support; for larger water droplets, the strong hydrophobic micro-windows can form "multiple ring-shaped supports" and "multiple isolated compressed air cushions", which can effectively prevent raindrops from penetrating the fabric; at the same time, the circular strong hydrophobic micro-windows can also maximize the protection of the raindrops to maintain a spherical shape, which is conducive to their timely rolling off.

[0022] 6) Comfort: By printing weakly hydrophilic micro-windows on the inside of the hydrophilic high-count high-density fabric, and making the square cell size of the grid much larger than the size of the moisture after the human body sweats, the human body sweat vapor and sweat can be transferred to the outside of the strongly hydrophilic fabric through the capillary wicking effect and vapor pressure difference of the hydrophilic fabric in the middle of the weakly hydrophilic unit cell, and then evaporated on the outside of the fabric; at the same time, the three-dimensional grid with weak hydrophilicity can also prevent the fabric from sticking to the skin, keeping the clothes comfortable.

[0040] The utility model will be described in detail through examples below, but the protection scope of the utility model is not limited to this.

[0041] Example 1
