Problems solved by technology

The pressing of the rubber and the fabric is through the control of the contact surface and viscosity, and then the pressure, so as to compound; the fabric itself will have a coating feel, which is not breathable enough, relatively thick, and cannot meet the requirements of light weight.
[0006] 2. Due to the hydrophobicity of aramid fibers, few people have tried in this area
The mature one-way moisture transfer technology is basically applied to ordinary chemical fiber products such as polyester and polyester capacyl. These are non-flame retardant products and cannot be used in working environments with high flame retardant requirements; for flame retardant fabrics, This technology is also an extremely urgent technical problem that needs to be solved
[0007] 3. For tooling, traditional cotton fabrics have this effect, but because cotton needs to be flame-retardant in the later stage, this effect will be greatly reduced, and the moisture accumulated in the fabric will evaporate, causing obvious discomfort to the human body
However, the more layers, the weight will also increase. For summer clothes, the light and thin requirements cannot be met.

Abstract

The invention discloses an aramid unidirectional moisture-wicking fabric and a preparation method thereof. Washing and drying, special moisture-conducting finishing (padding is scheduled, additives to control viscosity), one-way finishing (roller coating), drying and setting, etc., to obtain a light and thin aramid one-way moisture-conducting fabric. Through the above method, the product of the present invention has the characteristics of lightness and comfort, rich colors, high color fastness, etc., and has multi-functional protective properties such as high-efficiency flame retardant and heat insulation, antibacterial, moisture absorption and perspiration. The application field of nylon fabrics has greatly improved the comfort of light and thin fabrics; the process is easy to operate, cost-effective, and convenient for later industrialized scale-up production; it ensures the stability of PH value and excellent color fastness degree, the process is energy-saving and environmentally friendly.

Description

technical field [0001] The invention relates to the field of textiles, in particular to an aramid unidirectional moisture-wicking fabric and a preparation method thereof. Background technique [0002] At present, the working environment of industrial workers is becoming more and more complex. For users of flame-retardant protective clothing, the working environment is characterized by high temperature and stuffy heat. Compared with excellent protective performance, for workers, the long-term The comfort of time wearing is particularly important and practical. With the development of science and technology and the expansion of application fields, different flame-retardant protective products will provide workers with the best protection for different working environments. Development direction of burning textiles. [0003] Aramid fiber has good mechanical properties, flame retardant properties and stable chemical properties, but due to its linear macromolecular structure, i...
