Abstract

A fabric having high stretchability, favorable breathability, moisture absorption and moisture wicking capacities comprises an upper layer having a loose structure and a lower layer having a fine and dense structure. The loose structure comprises 3/1 twill, 4/1 twill, and 4 and 8 high-end charmeuse cottons. The fine and dense structure comprises jersey, 2/1 twill, and 2/2 edge lining. After completing repetition in the upper layer necessary for the design, a warp and/or a west is woven from the upper layer to the lower layer, and is woven back once again to the upper layer after completing repetition in the lower layer necessary for the design. Upon receiving an external force, the loose structure is naturally stretched out as if a spring is introduced into the fabric. In a fabric processing procedure, the fabric can shrink by 20-30%, thereby introducing permanent stretchability into the fabric.

Description

a fabric having high stretchability, good gas permeability and moisture wicking property

Technical field

The present invention relates to fabrics for use in a variety of textile applications (e.g., garment production, shoemaking, etc.), and more particularly to a versatile stretchable spring-like fabric.

Background technique

Textile wearers not only want clothing to protect the body from the outside world, but also provide a comfortable feeling. Conventional cotton fabric absorbs sweat from the body, but its low stretchability, poor breathability and poor moisture wicking make it impossible to provide the consumer with the required comfort. An elastic composite yarn and fabric is disclosed in U.S. Patent No. 20,100,281,842. This fabric provides good elasticity in the fabric but reduces comfort due to the presence of composite yarns in the fabric. The water absorption of such fabrics is significantly reduced. U.S. Patent No. 20110053449 discloses a laminated stretch fabric, but such fabrics also do not provide comfort to the user. U.S. Patent No. 5,217,782 discloses a multilayer fabric having moisture wicking properties, but which does not add additional stretch to the fabric. The inner layer of the fabric is a hydrophobic yarn and the outer layer is a hydrophilic yarn, which adds discomfort to the user.

In the above three patents, tensile or moisture wicking properties are introduced into the fabric, but none of the patents ensure that the fabric has both good stretchability, moisture wicking, high gas permeability and good strength. A 100% cotton fabric that ensures that the fabric can be stretched by about 15% and can be reduced by more than 95%, and this construction ensures that the water permeable fabric has a better pull than conventional fabrics. Extensibility.

Stretch the fabric.

Advantageous effects of the invention

Beneficial effect

The fabric with high stretchability and moisture wicking property provided by the present invention is a fabric using 100% cotton yarn similar to the spring structure, which overcomes the disadvantage of poor spreadability of the conventional cotton fabric, and the present invention provides The fabric is a stretchable fabric. When an external force is applied to both sides of the fabric in an outward direction, the fabric is stretched. Once the external force is released, the fabric returns to its original position. Fabric developed using this structure There are many benefits. The moisture wicking properties of these fabrics can be further improved by adding floats through the intermediate portions of the surface and back of the fabric. More complex structures can be developed while applying this innovative structure in the warp and weft directions to achieve simultaneous stretching in the warp and weft directions.

BEST MODE FOR CARRYING OUT THE INVENTION

Cotton is a natural fiber and is widely used in textiles due to its good hand and absorbency. The main limitation of cotton fabrics relative to synthetic fabrics is their poor scalability. For most stretchable woven fabrics, different types of stretchable weft yarns are primarily utilized to introduce stretch into the fabric. Such fabric stretching can be affected by heat and laundering, and the presence of the stretchable synthetic material also reduces absorption, causing discomfort to the user. In the present invention, a fabric similar to the spring structure has been developed which uses a complex interchangeable structure to introduce a natural stretch therein. Such stretching is not affected by external temperatures and laundering. And any 100% hot air yarn can be used to develop such a fabric that provides better comfort. Figure 1 illustrates the structure of the spring before and after the force is applied. Figure 2 illustrates that such a premium interchangeable fabric structure mimics a spring configuration in which loosely floating yarns with higher absorbency are still located on the upper surface of the fabric, and more closely spaced yarns are still located at the bottom of the fabric. The dense bottom layer of the fabric retains its original width or length while the top layer structure allows for stretching. Figure 2(b) illustrates how the fabric structure deforms like a spring when an external force acts on the fabric. Under the force, the curved portion of the fabric becomes flatter and allows the fabric to become longer. Once the external force is released, the structure returns to the original structure illustrated in Figure 2(a). In Figure 3, additional floats are inserted between the top and bottom layers to further enhance the interior to the outside of the garment. Water flows in the direction of the department. Figure 4 illustrates a simple fabric in which the fabric design is interchanged in two ways, wherein the surface is a floating twill fabric structure and the back side is a compact plain weave.

The mimetic spring structure in one embodiment of the invention has two designs as shown in Figures 4(a) and (b). In design 4(a), interchange occurs in the weft direction, and in 4(b), the warp and weft directions occur simultaneously. For both designs, the surface design is a floating twill fabric structure with a compact plain structure on the back. Using these designs, we developed three different 100% cotton fabrics weighing 4.4Oz/yd2, 5.6Oz/yd2 and 7.0Oz/yd2. Of the three fabrics, 4.4Oz and 5.6Oz fabrics were developed using the design of Figure 4(a), and the last fabric (7Oz) was developed using the design of Figure 4(b).

Table 1 shows the tensile results of these fabrics according to the ASTM D3107 standard, which is commonly used to test how many lycras a fabric contains. The fabric of the practice of the present invention does not contain lycra and contains only 100% veil. These results show that stretching from these fabrics is 10-13.5%, and permanent growth is limited to 3.5%. Figure 5 illustrates that such fabrics are much more stretchable at break points than conventional types of fabrics. These fabrics extend up to 50% before breaking.

[Table 1]

Table 2 shows the air resistance comparison of these fabrics and conventional cotton woven fabrics of the same weight. The results show that the air resistance properties of this fabric are about half that of conventional flat fabrics. This means that more air penetrates these fabrics and provides better comfort in the summer. Assuming it is infiltrated, this fabric is more powerful than a cotton flat fabric of the same weight. The degree of tear shown in Figure 6 suggests that these new fabrics have higher strength than conventional full flat fabrics. Finally, Figure 7 shows the test results of the moisture wicking test. Report shows fabric Has good moisture wicking properties. This means that the sweat produced on the human skin will be transmitted directly to the outer layer of the fabric to keep the skin dry.
