Description

Non-absorbent lightweight canvas

The present invention relates to a non-absorbent light canvas, in particular, a method in which the yarn is immersed in a water-blocking agent before the warp and weft yarns are woven into the base fabric, so that the yarn has a water-repellent effect, so that the yarn can be used. The upper and lower surfaces of the cloth are coated with a strong adhesive layer, and the adhesive layer is composed of an adhesive and a bridging agent, and the upper and lower adhesive films are respectively integrated with the upper and lower surfaces of the base fabric. It can be made into a practical canvas which has no water absorption, light weight, is not easy to peel and tear, and is not damaged by abrasion.

According to the conventional canvas, due to the process of manufacturing the canvas, the warp and weft yarns are first woven with the yarn to form the base fabric, and then the adhesive is sprayed on the upper and lower surfaces of the base fabric, and then the film is coated with the foregoing. The upper and lower surfaces of the base fabric are attached to each other to complete the manufacture of the canvas.

However, in order to improve the tensile strength of the canvas, the only way to improve the tensile strength of the canvas is to increase the strength of the warp and weft yarns of the base fabric. It can be found in Case No. 137743 of the invention, which is to raise the base fabric to 800 deniers. Denier, abbreviated D, or Daniel or Dan), to solve the problem of easy tearing of the canvas, and the fabric used in the currently commercially available canvas is between 210 and 500 denier. However, the increase in the number of yarns (the number of latitude and longitude) will increase the difficulty of fitting, and if the thickness of the film is increased, the weight of the canvas will increase, which will result in the end of the canvas shopper and the user. The greater the physical burden, and the larger the Danny number, the larger the diameter of the yarn, that is, the more easily it absorbs water, the rain or the moisture, the rain or moisture will be from the weakness of the canvas, such as the wear of the film. Or the tear or section of the canvas, through the warp and weft yarns of the base fabric, quickly absorb the water, and the water absorption rate reaches 100% without resistance, so that the weight of the canvas is immediately increased by a multiple, and the water absorbing yarn will At the same time, the adhesion between the film and the yarn is broken, and the two are quickly peeled off. And because the weight of the canvas increases, the user has to work harder to open or fold the canvas, which is not practical. That is, if you want to reduce the suction The only way to reduce the water rate is to reduce the Danny number and count of the warp and weft yarns of the base fabric, and increase the thickness of the film so that the diameter of the warp and weft yarns of the base fabric is as small as possible, but as mentioned above, Danny The lower the number of base fabrics, the canvas is easily peeled and torn, and the number of warp and weft yarns is reduced, which will make the sails less wear-resistant and easy to break.

In order to solve the problem of poor wear resistance and non-absorption rate of canvas, the commercially available canvas is intended to prevent moisture from being absorbed by the base fabric, and even wants to increase the thickness of the film and reduce the number of the film. To improve the wear resistance of the canvas surface. However, increasing the thickness of the film and reducing the number of yarns and counts can only slightly reduce the water absorption rate of the base fabric, but it becomes the cause of the easy tearing of the canvas. If it is really impossible to overcome, it will increase the weight of the canvas unit and cause the end. The burden and cost of canvas manufacturers and users.

To this end, the creator has accumulated decades of experience in the design and manufacture of related canvas products, and specifically studied the problems of the aforementioned conventional canvas, and created the case.

The purpose and motivation of this creation is to improve the shortcomings of the current commercially available canvas which is not wear-resistant, easy to peel, easy to tear, easy to absorb and overweight. This creation is based on the yarn before weaving. The water-blocking agent is soaked, so that the yarn can be combined with the water-blocking agent to reduce the water absorption rate of the yarn, and the base fabric of the warp and weft yarns with high tensile strength, low shrinkage, and moderately dense weaving density (counter density) The thickness of the adhesive layer on the upper and lower surfaces of the base fabric allows the base fabric and the upper and lower adhesive films to adhere to each other to achieve a canvas which is non-absorbent, not easily peelable, not easily torn, wear-resistant, and light in weight.

In order to achieve the above objectives, the non-absorbent lightweight canvas of the present invention is a base fabric woven from warp and weft yarns, and the yarn is first impregnated with a water-blocking agent before weaving, so that the yarn and the water-blocking agent are fully combined to The water absorption rate of the base fabric is lowered, and a strong adhesive layer is coated on the upper and lower surfaces of the base fabric, and the upper and lower adhesive films are respectively integrated with the upper and lower surfaces of the base fabric to form a A practical canvas that does not absorb water, is not easily peeled off, is not easily torn, is not damaged, and is light in weight.

The fabric of the non-absorbent light canvas of this creation is made of high-strength, low-shrinking high-denier (denier, abbreviated D, or Daniel or Dan) warp and weft yarns, with appropriate dense weaving The degree (weaving count) is used to increase the tearing strength and wear resistance of the canvas and to reduce the weight.

The non-absorbent light canvas of the present invention, wherein the adhesive of the adhesive layer is a composition resistant to hydrolysis, depending on actual needs.

The non-absorbent light canvas of the present invention, in order to combine the base fabric and the adhesive film, is a combination of a strong adhesive and a bridging agent to form an adhesive layer to overcome the problem that the water-blocking agent and the adhesive film contained in the yarn are not easily bonded.

In this way, in order to enable your examiner to fully understand the non-absorbent light canvas of this creation, the following is illustrated as follows: Figure 1, before the creation of canvas, the yarn must be woven into warp and weft yarns 10, 11 The base fabric 1, the warp and weft yarns 10, 11 used in the base fabric 1 before weaving, the sand drawing process needs to be first impregnated with a water blocking agent, so that the yarn sufficiently absorbs the water blocking agent, so that the aforementioned The base fabric 1 produces an excellent water blocking rate. After testing, the water absorption rate is reduced from 100% to 24 hours, and the water absorption rate is only 0.5cm. If it is made into canvas, it is drilled on the surface of the canvas and dripped with water droplets. Into, in 24 hours, the area of diffusion is only 1cm ² , which makes the creation almost reach 100% water blocking rate.

2 and 3, the non-absorbent lightweight canvas of the present invention is manufactured by applying an adhesive layer 2, 2a to the upper and lower surfaces 1a and 1b of the base fabric 1, and the adhesive layer 2, 2a. They are composed of a strong adhesive and a bridging agent. As for the bridging agent, it is adjusted according to the materials used by the water-blocking agent and the film. The purpose is to ensure that the base cloth and the film are closely adhered. After that, the thinner upper and lower adhesive films 3, 3a are respectively placed on the base fabric 1 and the table below. The surface 1a, 1b is integrated into one, and can be made into a canvas which has no water absorption, is not easy to peel and tear, is not damaged, and is light in weight.

The aforementioned base fabric 1 is composed of high tensile force of high denier (denier D, or Daniel or Dan), low-shrinkage and appropriate count-dense warp and weft yarn weaving, usually the higher the Danny number. The weaving count density is reduced, and the upper and lower adhesive films 3, 3a are attached to the substrate 1 with the strong adhesive layers 2, 2a, so as to enhance the tearing force that the canvas can withstand, even because of external force. The canvas is damaged, it is not easy to be torn, and the abrasion resistance of the canvas can be improved. Even during the driving process of the vehicle, even if there is a strong airflow impact, it can be avoided even if it is covered by the corners of the cargo or the vehicle body. Damaged, a small amount of adhesive layer can solve the repair problem, and can reduce the weight of the canvas, which is one-half or more of the weight of the commercially available canvas of the same grade.

The foregoing film may be composed of polyvinyl chloride (PVC), or thermoplastic polyurethane (TPU), or other water-resistant plastic materials, as long as the purpose of the creation can be achieved. The Danny number and density of the warp and weft yarns of the base fabric of the present invention are not limited.

In summary, the non-absorbent lightweight canvas of the present invention solves the problems of the water absorption rate of the base fabric and the weight of the canvas by raising the Danny number of the warp and weft yarns of the substrate, especially the users of the canvas are mostly It is used as a purpose to prevent foreign moisture from immersing the covering, such as the truck carrying the goods, and the obligation that the goods should be safely and non-delivery to the consignee. During the driving process, it will inevitably encounter rainy days, such as It is difficult to estimate the damage caused by canvas. It is difficult to estimate the damage caused by the canvas. At present, the trucks are operated independently by the driver. In the case of no assistants, in the case of instantaneous heavy rain, the canvas weight must be drawn when the canvas is pulled alone. It is not necessary to over-emphasize the demand, and this creation has indeed solved the shortcomings of the conventional canvas and enhanced the advantages of the canvas, which shows that the creation has already possessed novelty and progress, and is the composition of this case.
