Technical Field

The invention relates to the technical field of textile fabrics, in particular to an outdoor waterproof fabric.

Background

The waterproof breathable fabric has the main functions of: waterproof, moisture permeable, breathable, insulating, windproof and warm-keeping. In terms of manufacturing process, the technical requirements of the waterproof breathable fabric are much higher than that of the common waterproof fabric; meanwhile, from the quality, the waterproof breathable fabric also has the functional characteristics which are not possessed by other waterproof fabrics. The waterproof breathable fabric has the advantages that the air tightness and the water tightness of the fabric are enhanced, and meanwhile, the unique vapor permeability of the waterproof breathable fabric enables water vapor inside the structure to be rapidly discharged, so that mold breeding of the structure is avoided, the human body is kept dry and comfortable all the time, the problems of ventilation, wind prevention, water prevention, warm keeping and the like are perfectly solved, and the waterproof breathable fabric is a novel healthy and environment-friendly fabric. The real waterproof fabric can withstand the water seepage pressure and does not seep water even if being in a humid climate environment for a long time. For example, the shoes can not be soaked in water when walking outdoors with wind and rain for a long time and kneeling or sitting on a damp ground. Under the state of water vapor, water particles are very fine, and can smoothly permeate into the capillary to the other side according to the principle of capillary motion, so that the vapor permeation phenomenon is generated. When water vapor is condensed into water drops, the particles become bigger, and water molecules can not smoothly separate from the water drops and permeate to the other side under the action of the surface tension of the water drops (mutual pulling and balancing among the water molecules), so that the water permeation is prevented, and the vapor permeable membrane has a waterproof function.

The existing outdoor waterproof fabric usually has a certain waterproof effect, but the material is light and thin, so that the structural strength is low, and the problem of damage to the surface of clothes can be caused in long-term outdoor activities.

FIG. 1 is a schematic structural diagram of the present invention.

In the figure: 1 a primer layer, 2 a middle antibacterial layer and 3 an outer waterproof layer.

Detailed Description

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

Referring to fig. 1, the outdoor waterproof fabric comprises a fabric body, wherein the fabric body comprises a primer layer 1, a middle antibacterial layer 2 and an external waterproof layer 3 which are sequentially and tightly arranged; the base material layer 1 is formed by mutually weaving warps and wefts through nano silver fibers; the middle antibacterial layer 2 is formed by weaving silver-plated fibers; the external waterproof layer 3 is a vacuum nano-coating layer.

Wherein, the vacuum nano coating layer is at least one layer.

Wherein the vacuum nano coating layer is processed by a coating process by coating equipment.

In the embodiment, the coating equipment is adopted to enable the outdoor waterproof fabric to have a good waterproof function through a coating process, so that the fabric is waterproof and antibacterial due to the fact that the fabric is wrapped by single fibers, the fabric can have a good waterproof and hydrophobic function through vacuum nano coating technology treatment, and meanwhile the original heat retention, air permeability, comfortableness, portability and the like of the fabric can be well kept. In addition, the number of layers of the vacuum nano coating layer can be determined according to the actual situation, and two or more layers of coating can be coated, so that the use requirement of actual cloth is met. Meanwhile, the middle antibacterial layer woven by silver-plated fibers enables the cloth to have a very antibacterial effect, so that physical and psychological health of a human body is guaranteed.

Specifically, the angle of the contact angle on the vacuum nano coating layer is larger than 90 degrees.

In the present invention, it should be noted that the contact angle refers to an included angle formed by a tangent line of a gas-liquid interface at the intersection point of a gas, a liquid and a solid passing through a boundary line between the liquid and the solid-liquid interface, and when the angle of the contact angle is greater than 90 degrees, the surface of the solid is hydrophobic, that is, the liquid is not easy to wet the solid and is easy to move on the surface; and the angle of the contact angle can be preferably 150 degrees and is far greater than 90 degrees, so that the outdoor waterproof cloth is super-hydrophobic, namely the waterproof effect is better.

Specifically, the thickness of the outer waterproof layer 3 is 0.1-0.2mm, the thickness of the middle antibacterial layer 2 is 0.2-0.3mm, and the thickness of the primer layer 1 is 0.3-0.5 mm; in the actual design, the thickness of the cloth can be set according to the requirements of users, so that the cloth has the advantage of light weight.

Meanwhile, the film coating layer of the outdoor waterproof fabric is subjected to air permeability test, and researches prove that the air permeability is good and the softness of the fabric is not influenced.

In addition, in the present embodiment, the processing process and the coating equipment related to the vacuum nano coating layer are not substantially different from the prior art, and therefore, the structure and the processing process of the equipment are not described in detail herein.

In conclusion, the outdoor waterproof fabric realizes the wrapping of single fibers of the fabric, so that the fabric has waterproof and antibacterial properties, and the fabric can have excellent waterproof and hydrophobic functions through the vacuum nano-coating technology treatment, and can well keep the original warmth retention property, air permeability, comfort, portability and the like of the fabric.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
