Description
Technical Field
The invention relates to a fabric with a concave-convex structure and application thereof.
Background
In recent years, with the improvement of living standards, there has been an increasing demand for functionality of a jersey worn next to the skin, a T-shirt in spring and summer, underwear, a tight-fitting garment, and the like. This is because when people are doing sports or outdoor temperature is high in spring and summer, a large amount of sweat is easily produced, if the fabric can not be absorbed in time and is evaporated and diffused, the fibers which absorb moisture and swell may block the gap part of the fabric, so that the skin is in an anaerobic environment, and people feel very hot and stuffy, and the comfort is reduced.
At present, most of methods for reducing the adhesion property are to arrange a concave-convex structure on the back surface of the fabric to reduce the contact area with the skin so as to achieve the purpose of no body sticking. For example, patent document cn201510096595.x discloses a water-absorbing and quick-drying knitted fabric which is a single-sided circular knitted fabric and has a concave-convex structure on the back surface (back surface), wherein the height of the convex part in the concave-convex structure is 40 to 150 μm, the fiber forming the convex part is polyester elastic fiber, and the water-absorbing and quick-drying properties are excellent.
Further, for example, patent document CN201180049196.8 discloses a knitted fabric of a multilayer structure in which a specific amount of cellulosic long fibers is arranged in the vicinity of the back side (skin surface) surface of the fabric, thereby solving the problems of stuffy feeling at the time of non-perspiration or little perspiration, and sticky feeling, soft-wet feeling, cool feeling at the time of large-volume perspiration due to exercise, etc., but in fact, even if the skin contact surface is of an uneven structure, since the cellulosic long fibers having excellent water absorption and moisture absorption properties are used, part of the water remains on the skin contact surface, and the problem of soft-wet feeling is not fundamentally solved; in addition, as a double-sided knitted fabric, compared with a single-sided knitted fabric, the fiber gap is smaller, the time required for transferring moisture to the surface is relatively long, and the quick drying property is poor; but also has insufficient smoothness in hand feeling.
Disclosure of Invention
The invention aims to provide a fabric with a concave-convex structure and smooth handfeel and dry and comfortable muscle surface and application thereof.
The fabric at least comprises a coil A and a coil B, wherein the reverse side of the fabric is a weft plain stitch with a concave-convex structure, and the distribution coefficient of the concave-convex structure is more than or equal to 0.100, wherein the distribution coefficient of the concave-convex structure = (convex part spacing x convex part height)/convex part area.
The fabric has moderate distribution coefficient of the concave-convex structure on the back surface, reduces the contact area between the fabric and the skin, hardly causes the stuffiness and the attachment phenomenon of the clothes caused by sweating, and does not influence the smooth hand feeling even if the inner side of the fabric has the concave-convex structure. Can be widely used for manufacturing underwear, vests, sportswear, T-shirts, pajamas, tights, casual clothes and the like.
Drawings
FIG. 1 is a pictorial view of a cross section of the fabric of the present invention (50 magnification microscope, SUPERSCAN SS-550 microscope, manufactured by Shimadzu corporation, Japan) wherein E is a course formed by a coil of a line and F is a course formed by a coil of B line; l is the distance between the convex parts; h is the height of the convex part.
Detailed Description
As is known to all, after sweating, the sweat can fill the gaps among the fibers, and the contact between the sweat and the skin can form viscous resistance, increase the friction coefficient, influence the hand feeling and generate uncomfortable feeling, so that the back surface of the fabric is designed into a concave-convex structure, the contact area with the human body is reduced, the attachment is reduced, and the fabric has good comfortable feeling even in a wet state. The convex-concave structure distribution coefficient = (convex pitch x convex height)/convex area, where the convex refers to a portion of adjacent coils having a height difference and is greater than or equal to a reference with respect to a coil having a low height. The pitch of adjacent convex parts refers to the distance between the highest points of two adjacent coils (where the convex parts are in a row), and the unit is mm. The height of the convex part refers to the vertical distance from the highest point in the coil settling arc to the reference, and the unit is mm. The area of the projection is the surface area of the projection in mm2。
Generally, the larger the pitch of the projections, the smaller the adhesiveness, but if the pitch of the projections is too small, the contact area is not sufficiently reduced, and the adhesiveness is still large; if the pitch of the projections is too large, the liquid bridges are formed in the recesses and the projections, respectively, and the adhesion is further not reduced. The larger the area of the projection, the larger the area of contact with the skin per unit area, and the greater the adhesiveness. The larger the height of the convex portion, the smaller the adhesiveness, but the larger the frictional force, the rougher the hand. Based on the above, the distribution coefficient K of the concave-convex structure on the back surface of the knitted fabric is more than or equal to 0.100. When K is less than 0.100, the concave-convex structure is too small, the contact area of the fabric and a human body is too large, the fabric is easy to attach, and the feeling of stuffiness and itching is strong. In consideration of comfort and the like, the distribution coefficient K of the concave-convex structure is preferably 0.100-0.300.
In the invention, the coil A forms a coil row X, the coil B forms a coil row Y, and the ratio of the length of one coil row X to the length of one coil row Y is preferably 1.01-2.00, and more preferably 1.10-1.50. If the ratio of the line length is too large, the concave-convex degree tends to be increased, and the hand feeling may be influenced; if the ratio of the linear length is too small, the surface of the inner side (the reverse side of the fabric) tends to be flat, the adhesiveness tends to be increased, and the density of the fabric also tends to be increased, which may affect the air permeability.
In the present invention, the fineness of the yarn forming the loops a and B is preferably 20 to 130 deniers (hereinafter, referred to as D) in consideration of the influence of the fineness of the yarn on the touch of the textured structure.
The elastic fibers play a crucial role in the formation of the relief structure according to the invention. Preferably, in the present invention, each of the loops a and B includes an elastic fiber, and the uneven structure is realized by contraction of the elastic yarn. The elastic fiber is not particularly limited in kind, and may be a polyurethane fiber (PU), a polybutylene terephthalate fiber (PBT), a polytrimethylene terephthalate fiber (PTT), a polybutylene terephthalate/polyethylene terephthalate composite fiber (PBT/PET), or a polytrimethylene terephthalate/polyethylene terephthalate composite fiber (PTT/PET). Of course, the uneven structure may be realized by other means such as knitting using yarns of different thicknesses, using special yarns such as fancy yarns, and adopting a weave structure such as meshes and beads.
The adhesiveness of the present invention was evaluated by the peel angle, that is, the state when the fabric and the skin were just separated was simulated by the peel angle. The larger the peeling angle is, the more difficult the fabric and the skin are to be separated, and the adhesiveness is strong; the smaller the peel angle, the easier the separation of the fabric from the skin and the smaller the adhesiveness. In the present invention, the peeling angle is preferably 100 to 110 °.
The smoothness of the present invention is evaluated by the dynamic friction coefficient, and the smaller the dynamic friction coefficient, the better the smoothness. The smoothness was considered to be on a comparable level with a dynamic friction coefficient in the range of ± 0.02.
The concave-convex fabric can be used for manufacturing underwear, vests, sportswear, T-shirts, pajamas, tights or casual clothes and the like, and has the advantages of no adhesion to the body, smoothness, softness, good elasticity and the like.
The present invention will be further described with reference to examples and comparative examples.
