Description

Natural fiber weaving environment-friendly sun-shading fabric

Technical Field

The utility model relates to a sunshade fabric technical field, in particular to natural fiber weaves environment-friendly sunshade fabric.

Background

As is well known, the sun-shading fabric has the significance of shading, transmitting and ventilating. It can eliminate up to 86% of solar radiation, keep the indoor air smooth and see outdoor scenery clearly.

In recent years, with the continuous improvement of living standard of people, the traditional sunshade fabric can not completely meet the requirements of daily life of people, the ultraviolet resistance of the sunshade fabric in the prior art is low, and the sunshade fabric can mildew after long-term use and can not meet the requirements of people at present. The existing sun-shading fabric comprises a glass fiber fabric and a polyester fiber fabric, which are both prepared from high polymer fibers, and the fibers are relatively stiff, so that the overall hand feeling and comfort of the fabric are poor. The existing ultraviolet-resistant sun-shading fabric is obtained by finishing through a finishing agent with an ultraviolet-resistant function, reflects or absorbs ultraviolet rays, and achieves the effect of reducing ultraviolet projection. When the sun-shading fabric is glass fiber sun-shading cloth, a certain amount of glass fiber is arranged in the fabric, so that people are easily injured, and meanwhile, the skin of people is in contact with the glass fiber for a long time or the fabric coated with various preparations containing ultraviolet resistance, antibacterial agents and the like can cause discomfort such as itching feeling.

On one hand, the hemp fiber contains phenolic substances which can obviously kill and inhibit various bacteria. In addition, the hemp fiber is distributed with dense hemp gaps and small holes, which can absorb a large amount of oxygen in the air, so that anaerobic bacteria can not survive, and the aims of sterilization and bacteriostasis are achieved. On the other hand, the cross section of the hemp fiber is irregular triangle, polygon, waist circle and the like, and the middle cavity is linear or oval and is often different from the shape. From the molecular structure analysis of hemp fiber, the molecular structure has spiral lines, multiple edges and looser weight. After the light wave is radiated, diffuse reflection and multilayer light refraction are formed in the crystallization area of the hemp fiber, and the light wave is destroyed and absorbed in the amorphous area, the gap and the hole of the fiber molecule, so that the hemp fabric has good function of resisting ultraviolet radiation.

For example, patent CN 110804862 a discloses a preparation method of a low-extension fireproof sunshade fabric, and for example, patent CN110409190A discloses an ultrathin glass fiber sunshade fabric and a preparation method thereof, and a zero-opening and opaque polymer composite sunshade fabric and a preparation process thereof disclosed in patent CN 110735214 a. The sun-shading fabric in the patent is of a planar structure, and compared with a three-dimensional structure, the planar structure is relatively small in specific surface area, and relatively small in coating area for absorbing ultraviolet rays and an antibacterial agent on the fabric, so that relatively poor in ultraviolet ray resistance and antibacterial performance.

Therefore, the sun-shading fabric which can improve the ultraviolet resistance, resist mildew, is environment-friendly, comfortable in hand feeling and good in drapability is urgently needed.
