Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

Referring to fig. 1, the breathable multifunctional fabric comprises a skin-facing layer 1 and a hydrophilic moisture absorption layer 2 compounded on the outer side of the skin-facing layer 1, wherein the skin-facing layer 1 and the hydrophilic moisture absorption layer 2 are formed by compounding TPU (thermoplastic polyurethane) breathable hot melt adhesive films, the permeability of water vapor between the composite fabrics is guaranteed, the skin-facing layer 1 is formed by interweaving warp yarns 11 and weft yarns 12, and the warp yarns 11 and the weft yarns 12 are twisted wrapping yarns which repel water relatively. The skin layer 1 is formed by weaving twisting covering yarns which are relatively water repellent, on one hand, the humidity gradient difference exists between the inner layer fabric and the outer layer fabric, meanwhile, the skin layer 1 adopts the twisted covering yarns, the fibers of the core wires are thinner due to twisting, the fibers of the covering yarns are thicker, the pressure difference exists between the core wires and the covering yarns on the inner side and the outer side, a differential capillary effect can be formed, and liquid water is directionally transmitted and diffused by the inner core and then is transmitted to the fiber capillary tubes in the yarns on the outer side.

Wherein the content of the first and second substances,

with further reference to fig. 2 and 3, the warp 11 includes a memory tow a111 as a core, and an elastic yarn a112 and a moisture absorption yarn a113 wrapped outside the memory tow a111 and twisted; the weft 12 comprises a memory tow b121 as a core wire, and an elastic yarn b122 and a moisture absorption yarn b123 which are wrapped outside the memory tow b121 and twisted. The memory tows serving as core wires are arranged and covered with the elastic yarns, so that the fabric can be kept flat during subsequent fabric weaving and post-treatment, and the elastic yarns can assist the memory tows to recover deformation; the moisture absorption yarn is arranged to increase the water absorption capacity of the attaching layer 1, so that water can be conveniently transferred to capillary tubes of yarn fibers, and the moisture conduction capacity is increased by matching with the structure of the yarn.
