Description

A fabric with moisture management

technical field

The invention relates to a fabric, especially a fabric whose structure is similar to that of a plant, and which has good moisture management function.

Background technique

With the improvement of living standards, people's requirements for clothing not only stay on the most basic function of keeping warm, but more and more pursue the comfort of wearing. Although pure cotton clothing has good sweat-absorbing properties, its sweat-wicking effect is not good, and the wearer will feel discomfort such as dampness and coldness after exercise. Therefore, developing a fabric with good moisture management function has become a common goal in the industry.

US Patent No. 5,217,782 discloses a multilayer fabric with moisture management function. It consists of a thicker inner layer made of hydrophobic fibers with good water permeability; a thinner middle hydrophilic layer and a thicker outer hydrophilic layer. In this way, since the fibers of the inner layer are hydrophobic, moisture can be quickly transferred to the outer layer without staying in the inner layer, thereby making the wearer feel more comfortable.

Another US patent US6,432,504 discloses a composite fabric with moisture management function. It works to transport moisture from the skin to the outer layers by capillary action. The composite fabric includes an inner hydrophilic layer of coarser fibers and an outer hydrophilic layer of finer fibers.

Although the fabrics disclosed in the above two patent documents can achieve a certain degree of water permeability, their water transport properties need to be further improved. In addition, since the density of the fibers of the inner layer in contact with the skin is substantially the same as that of the fibers of the outer layer, the fabric as a whole has poor air permeability.

Contents of the invention

In view of the above-mentioned problems in the prior art, the main purpose of the present invention is to provide a fabric with moisture management function, which not only has good moisture transport properties, but also can improve the air permeability of the fabric.

In order to achieve the above object, the present invention provides a fabric with moisture management function by imitating plants in nature, wherein the fabric is composed of the following three layers: the bottom layer, which is similar to the stem of the plant, and the bottom layer is leno (leno) ) structure, multiple yarns are twisted together to form a plurality of fabric units; the bottom layer is in contact with the skin of the human body; the middle layer is similar to the branches of plants, and the yarns of the fabric units are initially separated in the middle layer, form a basket weave structure, a puffy structure or a honeycomb structure; a top layer, which is similar to a leaf of a plant, where the yarns of the said fabric elements are further separated to form a flat weave structure; the fabric thus constituted, can be formed on the fabric yarn Capillary action transports moisture from the bottom layer to the middle layer and out of the top layer for good moisture management properties.

The fabric adopting the structure of the present invention, because it has a plant-like structure, can effectively transmit moisture, thereby greatly improving the moisture transmission performance of the fabric in the prior art.

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

Detailed ways

Plants are natural organisms that cover the surface of the earth. Plants not only perform photosynthesis, the most important biological activity for sustaining life on Earth, but also provide the planet with essential proteins and, most importantly, plants have excellent water transport properties. Through the unique structure of plants, groundwater can be transported from tree roots to leaves against its own gravity. Studies have shown that the good water transport characteristics of plants are determined by their unique structural features. Plant leaves have a larger surface area to volume ratio than stems, which form a unique tree-shaped network that is very conducive to water transport. This tree-like network also exists in other places in nature where fluids flow naturally, such as river basins, human lungs, blood vessels, and so on. This confirms the advantage of the tree network in water transport from another aspect.

The present invention imitates the above-mentioned structural characteristics of plants in the structure of the fabric, that is, forms a tree network to realize the good moisture transmission characteristics of the fabric. Materials formed with a tree-like network have excellent moisture transport properties and thermal properties. This material is ideal for clothing because it wicks sweat and moisture well, keeping the wearer dry and comfortable. There are also other applications, such as carpets, artificial turf, geotextiles, etc., to keep the area they cover dry.

Fig. 1 shows a schematic view of the structure of the fabric with plant structure of the present invention.

As shown in Figure 1, the fabric of the present invention is a three-layer woven fabric, the bottom layer 30 in contact with the skin is a leno structure in which four or more strands of yarn are twisted together to form a plurality of stem-shaped Fabric units 40, each fabric unit 40 is arranged side by side. The fabric unit 40 ("four-strand") splits the middle layer 20 above the bottom layer 30 into two-strand branches whereby the middle layer can be formed into a hopsack structure, huckaback Structure or honeycomb structure, like the branch structure of a plant. The top layer 10 above the middle layer 20 is a plain weave in which the yarns are separated in the top layer 10 to obtain a larger surface area to volume ratio. The upper surface of the top layer may be further processed to form hairs and/or loops to mimic plant leaves. Alternatively, the lower surface of the base layer can be brushed to mimic plant roots, further enhancing the moisture transport properties.

Physical and chemical treatments of fabrics, yarns and fibers are also possible. For example, hydrophilic treatment can be performed on the bottom surface, and the hydrophilic treatment method includes oxygen plasma treatment and oxidation treatment, etc., so as to further enhance the water absorption performance. The treated fabric facilitates moisture transport through different fiber and yarn combinations than existing moisture management fabrics. This novel clothing material has strong capillary action and a strong cohesion mechanism due to its tree-like network structure. Moreover, the air convection and permeability near the skin are greatly improved due to the large space interval between the "stem" and "stem" at the bottom of the fabric.

In order to verify the moisture transport performance of the fabric of the present invention, two fabrics with different structures were woven from the same wool yarn, and their water transport properties were compared. Fabric A has the tree structure of the present invention as shown in FIG. 1 , and fabric B has the double-layer plain weave structure of the prior art. A special tester is used to measure the moisture transfer performance between the above two fabric surfaces. During the test, the fabric sample is in contact with a horizontal surface with a constant water level. The amount of water transmitted and absorbed through the fabric sample is measured in real time. Figure 2 shows the comparative results for the two fabrics.

As can be seen from Figure 2, the amount of water entering and being transported by fabric A is much faster and greater than the amount of water entering and being transported by fabric B. Since the two fabrics are woven from the same yarn, it is clear that the difference in the moisture transport capacity mentioned above is caused by the different fabric construction. Fabric A is suitable for use as clothing or other covering material due to its excellent water transport characteristics.

The present invention imitates the structure of plants in the fabric structure. The beneficial effect of this is that good water transport properties are obtained.
