Description

Technical Field

[0001] The utility model belongs to the technical field of webbings, and in particular relates to a webbing with three-proof functions. Background Art

[0002] Ribbon is a narrow or tubular fabric made of various yarn raw materials. As an auxiliary product, it is widely used in the fields of clothing, luggage, etc.

[0003] Most of the webbings on the market are woven with conventional yarns. This product does not have the three-proof (waterproof, oil-proof, and anti-fouling) functions, which leads to certain usage restrictions of these webbings in luggage, outdoor clothing, and outdoor equipment. For example, thin children's down jackets often have three-proof fabrics, but the edging at the cuffs cannot achieve the three-proof properties, resulting in children's cuffs getting wet and dirty after playing in the water.

[0004] There are also some waterproof webbings on the market. Commonly used waterproof webbings are produced and woven by coating waterproofing, and a waterproof coating is added to the surface of the webbing to achieve the three-proof effect on the surface of the webbing; some waterproof webbing products are treated with three-proof additives to achieve the waterproof function, and the hydrophobic material is adsorbed on the surface of the webbing to achieve the waterproof effect of the webbing.

[0005] However, achieving waterproofing through coating treatment will increase the thickness of the ribbon itself, reduce the softness of the ribbon, and there is a risk of coating falling off; and products that use three-proof additives to achieve ribbon waterproofing will have the problem of the waterproof effect deteriorating after multiple washings and the dilution of the additives, and eventually lose the three-proof effects.
