Moisture-absorbing breathable smooth-wrapped soft elastic Lioming fabric, application and preparation method
Technical Field
The invention relates to a moisture-absorbing breathable smooth-wrapped soft elastic Lioming fabric, an application and a preparation method thereof, and belongs to the technical field of functional textile materials.
Background
With the improvement of living standard of people and pursuit of healthy life style, the demand of functional fabrics is increasing. Among the many demands, moisture absorption, breathability and a smooth feel of wrap are important developments in modern garment materials. For example, in the field of sportswear, good moisture absorption and air permeability can effectively absorb sweat discharged by a human body, keep skin dry and avoid stuffiness and discomfort caused by sweat accumulation. In addition, the smooth fabric wrapping sense can provide better fit for a wearer, reduce friction between clothes and skin and improve wearing comfort.
However, the existing fabric technology still has some defects in the aspect of realizing moisture absorption, ventilation and smooth wrapping feeling. For example, some fabrics have good hygroscopicity, but poor air permeability, resulting in a noticeable smoldering feel when worn. While other fabrics have better air permeability, but have poor performance in moisture absorption and sweat release, and cannot meet the requirements of human bodies in sports or high-temperature environments. In addition, some fabrics tend to sacrifice elasticity and flatness while seeking softness and comfort, resulting in a lack of support feel when worn.
To overcome these shortcomings, attempts have been made to produce a variety of composite and functional fiber fabrics on the market. For example, the fabric with a multilayer structure design is adopted, and various functions such as moisture absorption, ventilation, heat preservation and the like are realized through fiber characteristics of different layers. However, the preparation process of these fabrics is often complex, and in practical use, the bonding strength and functional stability between the layers still need to be further optimized.
Therefore, the development of the soft elastic hexamine treatment fabric with the functions of moisture absorption, ventilation and flat package has important significance for meeting the high performance requirements of modern clothing and home textile fabrics. The fabric can effectively absorb and emit human sweat, and simultaneously provides good elasticity and fit, so as to meet the requirements of various wearing and use scenes such as sports, leisure, sleeping and the like.
