Abstract

The invention provides a multifunctional fabric, and belongs to the technical field of textiles. The multifunctional fabric comprises an inner layer made of a component A, a middle layer made of a component B and an outer layer made of a component C; the inner layer, the middle layer and the outer layer are mutually attached, wherein the component A accounts for 3-15%, in percentage by mass, of the total mass of the whole multifunctional fabric, the component A comprises heavy denier ultrahigh weight polyethylene fiber and fine denier ultrahigh weight polyethylene fiber, the heavy denier ultrahigh weight polyethylene fiber accounts for 91-99% of the total mass of the component A, the component B is highly moisture-absorbing fiber, the component C is lowly moisture-absorbing fiber, the moisture regain difference value of the component B and the component C is higher or equal to 2.5% under the condition that the relative humidity is higher than or equal to 50%. Compared with the prior art, the multifunctional fabric has the superior functions of being soft, skin-friendly, hygroscopic and sweat releasing, cool and bacteriostatic, can have different levels of cooling effects along withthe difference of the relative humidity of the inner layer contact face, and meanwhile, the cost of the multifunctional fabric is remarkably lowered.

Description

technical field [0001] The invention belongs to the technical field of textiles and relates to a composite functional fabric. Background technique [0002] Functional fabrics refer to new fabrics with some special functions in addition to the physical and mechanical properties of general fabrics. Typical functions include: health care (antibacterial, mite removal, physical therapy and odor removal, etc.), safety protection (flame retardant , anti-radiation, anti-static, anti-ultraviolet, etc.), health and comfort (heat absorption, heat release, moisture absorption, moisture removal, etc.), medical and environmental protection (biocompatibility and biodegradability), etc. [0003] With the continuous improvement of people's quality of life, fabrics with composite functions such as health and comfort are increasingly favored, and have become one of the high-tech products with rapid development and huge market space in recent years. At present, there are hundreds of varieties ...
