Description

High waterproof cloth

Technical Field

The utility model relates to a waterproof coated fabric, especially an outdoor apparatus or industrial high waterproof cloth.

Background

The coating cloth is prepared by dissolving required coating colloidal particles into a salivation shape by using a solvent, uniformly coating the salivation shape on cloth in a scraper mode, and drying the cloth by using an oven to form a layer of uniform covering glue on the surface of the fabric, wherein the common functions of the coating cloth are water resistance, flame retardance, ultraviolet resistance and the like. The basic principle of the waterproof coating cloth is that a complete coating is utilized to form a film-like effect, and water is isolated from the cloth. It follows that, once the coating on the surface is broken or worn, functional gaps are formed and the water-proofing effect is greatly reduced.

The existing waterproof cloth is mostly used for outdoor appliances such as umbrellas and tents, or industrial goods such as goods rain shelters, and basically adopts a high-strength woven structure. However, woven structures are also provided with small holes resulting from weaving. The coating shrinks after being dried, the coating at the edge of the small hole is attached to the yarns of the cloth, and the coating at the center of the small hole lacks attachments, so that the difference of shrinkage stress at different parts is formed. Although the existing waterproof cloth has better waterproof effect in the early stage of use. However, as the service time increases, the coating at the small holes is easy to crack and peel after the cloth is folded by being unfolded and rolled for many times. More importantly, once the coating begins to peel, the stress and adhesion distribution begins to be uneven, the peeling speed is faster and faster, the coating is generally radial, and the waterproof effect also begins to be reduced.

Therefore, the existing waterproof coating cloth has the problem of insufficient and durable waterproof effect.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a high tarpaulin. The utility model discloses on the basis that structural strength is high, still have lasting water-proof effects. Furthermore, the utility model discloses a production is simple relatively, and application scope is wide.

The technical scheme of the utility model: a high waterproof cloth comprises a cloth layer, wherein a waterproof coating is arranged on the surface of the cloth layer; the cloth layer is of a woven structure woven by the attached yarns, the attached yarns comprise cotton core wires, the surface of each cotton core wire is provided with attached fibers, and polyester threads are twisted outside the cotton core wires; the number of the polyester threads is 2, the two polyester threads are divided into an inner layer and an outer layer which are twisted in opposite directions, and gaps through which attached fibers pass are formed in the twisted polyester threads.

In the high waterproof cloth, the waterproof coating is arranged on both sides.

In the above-mentioned high waterproof cloth, the cloth layer is a plain weave or a twill weave.

In the above-mentioned high waterproof cloth, the waterproof coating is a fluorine-based waterproof agent coating.

Compared with the prior art, the utility model discloses a cloth adopts the adhesive yarn to make into, and the adhesive yarn is the surface to have the fibrous structure of adhesion. Therefore, on the surface facing the outside, the amount of the attached fibers on the single attached yarn is small, and the coating is hardly influenced; and four attached yarns are gathered at the small holes formed by weaving, so that the density of the attached fibers is multiplied, and the attached fibers can be used as attachments of the coating at the small holes, thereby playing a role similar to a steel bar in concrete, reducing the shrinkage stress difference between the coating at the small holes and the surrounding parts, and further effectively prolonging the initial stripping time of the coating. Also, the peeling of the coating requires tearing of the attachment fibers from the attachment yarns due to the addition of the attachment. Therefore, even if the coating starts to peel off, the peeling speed is slower than that of the conventional tarpaulin because the force required for dropping is large. From this, the utility model discloses can realize guaranteeing the integrality of coating for a long time, realize lasting water-proof effects. In addition, the center of the attached yarn is the cotton yarn for picking hair, and the double-layer bidirectional polyester yarn is used for twisting to improve the strength. The process is a relatively mature process regardless of the plucking of cotton yarns, twisting of polyester yarns and subsequent gluing, and does not need to customize complex production equipment, so that the production process is relatively simple.

Further, a double-sided coating may further extend the effective water-proofing time. And the utility model discloses still can select the organizational structure according to concrete needs, wherein plain weave intensity is high, and the hardness is higher, is applicable to the industry occasion, and the twill prevents that intensity is lower relatively, but hardness is also low, and the compliance is better, is applicable to civilian commercial occasion.

To sum up, the utility model discloses on the basis that structural strength is high, still have lasting water-proof effects. Furthermore, the utility model discloses a production is simple relatively, and application scope is wide.

Detailed Description

The present invention will be further described with reference to the following examples, which are not intended as a limitation to the present invention.

Example (b): a high waterproof cloth comprises a cloth layer 10, and waterproof coatings 20 are arranged on two surfaces of the cloth layer 10. The cloth layer 10 is a woven structure woven by attached yarns, the attached yarns comprise cotton core wires 11, attached fibers 12 are arranged on the surfaces of the cotton core wires 11, and polyester yarns 13 are additionally twisted on the cotton core wires 11; the number of the polyester threads 13 is 2, the two polyester threads 13 are divided into an inner layer and an outer layer, the twisting directions are opposite, and gaps through which the attached fibers 12 pass are arranged on the twisted polyester threads 13.

The cloth layer 10 is a plain weave, which has high strength, but high hardness and is suitable for industrial occasions. Twill weave can also be selected as required to cloth layer 10, and although twill weave intensity is lower than plain weave, the compliance is better, is applicable to civilian occasion.

The waterproof coating 20 is a fluorine-based waterproof agent coating, and the fluorine-based waterproof agent can be a PF-206 type waterproof agent sold by Anhui chemical Co., Ltd.

The working principle is as follows:

the utility model discloses a cloth adopts the adhesive yarn to make into, and the adhesive yarn is that the surface has the structure of adhering to fibre 12. On the outward facing side, the amount of binder fibers 12 on the individual binder yarns is low, with little effect on the coating; and four attached yarns are gathered at the small holes formed by weaving to increase the density of the attached fibers 12 by times, so that the attached fibers 12 can be used as attachments of the coating at the small holes to play a role similar to steel bars in concrete, the shrinkage stress difference between the coating at the small holes and the surrounding parts is reduced, and the initial stripping time of the coating is further effectively prolonged. Also, the peeling of the coating requires tearing the attachment fibers 12 from the attachment yarns due to the increased attachment. Therefore, even if the coating starts to peel off, the peeling speed is slower than that of the conventional tarpaulin because the force required for dropping is large. From this, the utility model discloses can realize guaranteeing the integrality of coating for a long time, realize lasting water-proof effects.

The cotton yarn is spun yarn before drafting, and the spun yarn is still thicker than the yarn in the textile industry, so that a large amount of attached fibers 12 can be grabbed by the spun yarn. Because the double-layer polyester yarn 13 is twisted reversely, part of the attached fibers 12 can leak out at a lower twist, and the twisted attached yarn still has better strength. The attachment yarn is the structure of the covering yarn, the cotton yarn in the middle being theoretically untwisted.
