Polyvinyl alcohol antifouling wash-free fabric

Technical Field

The utility model relates to a surface fabric technical field, specific antifouling no-wash surface fabric of polyvinyl alcohol.

Background

The waterproof self-cleaning fabric for the existing clothes is generally characterized in that a layer of waterproof coating is coated on the surface of the fabric, water is blocked in a mode that a hydrophobic compound is deposited on the surface of a fiber, pores are reserved on the surface of the fabric, air and water vapor can permeate through the pores, water drops and water drops are formed on the surface of the fabric when water flows pass through the pores, and then the water drops and the water drops flow away, so that the waterproof and antifouling effects are achieved.

However, the pattern layer gradually falls off after being worn and cleaned, and at the moment, the first layer of fabric is soaked by water, so that the waterproof function is invalid.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the utility model provides a polyvinyl alcohol antifouling no-clean fabric.

In order to achieve the above purpose, the present invention is realized by the following technical solution: a polyvinyl alcohol antifouling no-clean fabric structurally comprises: the warp and the weft are woven in a warp and weft manner to form a weft-rib weave, and both the warp and the weft comprise: the fiber drawing-resistant composite fiber is spirally and tightly wound on the outer layer of the fiber drawing-resistant composite fiber.

Furthermore, the composite fiber is PVA nanofiber, namely PVA nanofiber prepared by mixing and spinning high-molecular polyvinyl alcohol and alkyl aprotic solvent solution.

The alkyl aprotic solvent solution is a modifying solvent and is used for modifying a fiber made of high molecular weight polyvinyl alcohol.

Furthermore, at least three strands of the composite fibers are tightly wound on the anti-wiredrawing outer layer, so that the strength and the hydrophobic contact surface of the manufactured warp and weft are ensured to the minimum extent.

Furthermore, the outer surfaces of the warp yarns and the weft yarns are both the composite fibers which are tightly attached, so that water is prevented from penetrating into the anti-wiredrawing yarns.

Furthermore, the contact angle of the surface of the fabric formed by the warps and the wefts and water is 150-185 degrees, and the rolling angle is 2-10 degrees, so that water forms water drops on the surface layer of the fabric, and the water drops can easily roll on the surface layer of the fabric.

Furthermore, the anti-drawing fiber is a fiber-forming high polymer, namely polyester fiber, which is prepared by esterification reaction of purified terephthalic acid and ethylene glycol, so that the anti-drawing fiber can obtain stronger tensile strength under the condition of certain elasticity.

Advantageous effects

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the utility model discloses a polymer polyvinyl alcohol makes nanofiber for the raw materials to utilize alkyl aprotic solvent solution to modify it, make the nanofiber that has super hydrophobicity surface, and interweave into the surface fabric, make clothes, tie that use this kind of surface fabric to make be stained with filths such as rainwater, grease, printing ink not, thereby reach self-cleaning function of exempting from to wash, and be afraid of wearing and tearing and washing, can use for a long time.

2. The utility model discloses closely twine composite fiber and make warp and woof on anti wire drawing, all obtain stronger tensile strength in radial and latitudinal direction from this, and then make the surface fabric that interweaves and form have stronger tensile strength.

Examples

As shown in fig. 1-3, the utility model provides a polyvinyl alcohol antifouling no-clean fabric, the structure of which comprises: warp 1 and woof 2, warp 1 with woof 2 warp and weft knitting forms the weft-heavy level tissue, warp 1 with woof 2 each includes: the composite fiber comprises a fiber drawing resistance a and a composite fiber b, wherein the composite fiber b is spirally and tightly wound on the outer layer of the fiber drawing resistance a.

The composite fiber b is PVA nanofiber, namely PVA nanofiber prepared by mixing and spinning high-molecular polyvinyl alcohol and alkyl aprotic solvent solution.

In this example, a high molecular polyvinyl alcohol was spun into nanofibers, and then the polyvinyl alcohol nanofibers were subjected to a surface hydrophobic modification treatment by dipping with an alkyl aprotic solvent solution, thereby producing composite fibers b having high hydrophobicity.

The anti-drawing yarn a is a fiber-forming high polymer, namely polyester fiber, prepared by esterification of purified terephthalic acid and ethylene glycol, so that the tensile yarn a has high tensile strength under the condition of certain elasticity.

At least three strands of the composite fibers b are tightly wound on the outer layer of the anti-wiredrawing a, so that the strength and the hydrophobic contact surface of the manufactured warp yarns 1 and weft yarns 2 are ensured to the minimum.

In this example, a composite fiber b having high hydrophobicity is spun around a ripstop a so that the outer layer of the ripstop a is tightly wound with the composite fiber b, and the resultant yarn is used as warp 1 and weft 2 of the fabric and woven into a weft rib fabric.

The outer surfaces of the warp yarns 1 and the weft yarns 2 are both the composite fibers b which are tightly attached to each other, so that water is prevented from permeating the tensile yarns a.

The contact angle of the fabric surface formed by the warp yarns 1 and the weft yarns 2 and water is 150-185 degrees, and the rolling angle is 2-10 degrees, so that water forms water drops on the fabric surface, and the water drops can easily roll on the fabric surface.

In the embodiment, the fabric is used for manufacturing clothes, when water is splashed on the clothes, water drops are formed on the surface of the fabric of the clothes due to the high hydrophobicity of the warp yarns 1 and the weft yarns 2 caused by the composite fibers b, and the water drops roll easily due to the rolling angle smaller than 10 degrees, so that the clothes fall off, the self-cleaning and washing-free functions are achieved, the fabric is not afraid of abrasion and washing, and the fabric can be used for a long time.

All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.
