Abstract
Description
Technical Field
[0001] This utility model relates to the field of fabric technology for conveyor belts, and in particular to a polyester-based release fabric. Background Technology
[0002] Existing polyester fabric is used as a conveyor belt to transport fluid objects. When the objects solidify, they are not easily separated from the belt. The current method is to circulate a release agent on the surface of the fabric to facilitate separation. Although this method solves the problem of separation of objects from the belt, it leads to complex equipment, increased production costs, and increased environmental pollution. Utility Model Content
[0003] The present invention aims to provide a polyester-based release fabric from which objects can be easily separated, solving the problem that existing fabrics used for conveying objects are difficult to separate once the objects are solidified on them.
[0004] The above technical problems are solved by the following technical solution: a polyester-based release fabric, comprising a polyester fabric including a plurality of warp yarns and a plurality of weft yarns woven together, characterized in that a release layer is provided on the surface of the polyester fabric, the gap between adjacent weft yarns is larger than the dimension of the warp yarns along the thickness direction of the polyester fabric, and adjacent warp yarns abut together. The release layer allows the object to be easily detached and removed from the invention when it is held and cured by the invention. The invention also exhibits good density.
[0005] Preferably, the weft yarn is wrapped with a weft release layer, and the warp yarn is wrapped with a warp release layer, the weft and warp release layers constituting the release layer. This design facilitates the formation of the release layer, allowing it to be processed simultaneously with the warp and weft yarns. However, the warp and weft yarns are slippery and prone to unraveling.
[0006] Preferably, the release layer is formed by curing a fluid release material onto the surface of a polyester fabric. The release layer also serves to fix and position the warp and weft yarns, but it has poor air permeability.
[0007] Preferably, the invention also includes a plurality of air vents, which penetrate the polyester fabric and the release layer along the thickness direction of the polyester fabric. This allows for the permeability of the invention.
[0008] Preferably, the vent holes are rigid tubes bonded to the polyester fabric via a release layer. This prevents the vent holes from being compressed during use, thus improving the reliability of ventilation.
[0009] Preferably, the rigid tube is located between adjacent weft yarns and between adjacent warp yarns. This avoids the rigid tube causing warp or weft yarn breakage.
[0010] Preferably, a rigid tube mounting plate is also included. The plate has a connecting post for inserting into one end of the rigid tube, and a cap is provided at the other end of the rigid tube. The outer end face of the cap is conical, and the cap is made of ferromagnetic material. The method for installing the rigid tube onto the polyester fabric is as follows: The rigid tubes are fitted one-to-one onto the connecting post, aligning the tip of the cap with the gap between the weft yarns. Before the release layer material cures, the rigid tube mounting plate is pressed down, causing the rigid tube to insert into the polyester fabric. After the release layer cures, the connecting post is pulled out of the rigid tube, and the cap is removed using a magnet. The conical design of the cap allows the warp yarns to be separated during insertion, thus preventing yarn breakage.
[0011] Preferably, the weft yarns have a straight structure, with the same warp yarn located below one of two adjacent weft yarns and above the other; and between two adjacent warp yarns, one warp yarn is located below a weft yarn and the other is located above the same weft yarn. When weaving polyester fabric, grooves extending along the weft direction can be formed on the surface of the polyester fabric, while during use, they travel along the warp direction, thus enabling more reliable propulsion of objects.
[0012] Preferably, the weft yarn has a circular cross-section. This makes yarn production convenient.
[0013] Preferably, the weft yarn has a rectangular cross-section, and the dimension of the weft yarn along the warp direction is larger than the dimension of the weft yarn along the thickness direction of the polyester fabric. With the same cross-section for the weft yarns, the surface of the workpiece can be made smoother while maintaining the weft-direction grooves to increase conveying reliability.
[0014] This invention has the following advantages: by providing a release layer, objects can be easily separated after curing. This eliminates the need for a release agent during separation, reducing production costs. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example 1, see Figure 1 A polyester-based release fabric includes a polyester fabric comprising a plurality of warp yarns 1 and a plurality of weft yarns 2, which are woven together. A release layer 3 is provided on the surface of the polyester fabric. In this embodiment, release layers are provided on both the upper and lower surfaces; however, to prevent slippage during driving, a release layer can be provided only on the side in contact with the object. The gap between adjacent weft yarns is larger than the dimension of the warp yarns along the thickness direction of the polyester fabric, and adjacent warp yarns abut together. The release layer is formed by curing a fluid release material onto the surface of the polyester fabric. The material of the release layer is silicone. The weft yarns have a straight structure; a single warp yarn is located below one of two adjacent weft yarns and above the other; among two adjacent warp yarns, one warp yarn is located below a weft yarn and the other is located above the same weft yarn. The cross-section of the weft yarn is circular. Example 2 differs from Example 1 in that: See Figure 2 The cross-section of the weft yarn is rectangular, and the dimension of the weft yarn along the warp direction is greater than the dimension of the weft yarn along the thickness direction of the polyester fabric.
[0019] Example 3, see Figure 3 and Figure 4 Based on Examples 1 and 2, the following improvements can be made (only the case where the weft yarn is rectangular is shown in the figure; the same principle applies to circular yarn).
[0020] It also includes several vent holes 4, which penetrate the polyester fabric and the release layer along the thickness direction of the polyester fabric. The vent holes are formed by the inner holes of rigid tubes 5 bonded to the polyester fabric through the release layer. The rigid tubes are located between adjacent weft yarns and between adjacent warp yarns. It also includes a rigid tube mounting plate 6, which has a connecting post 7 for inserting into one end of the rigid tube. A cap 8 is inserted through the other end of the rigid tube, and the outer end face 9 of the cap is conical and made of ferromagnetic material. The method for installing the rigid tubes onto the polyester fabric is as follows: the rigid tubes are fitted one-to-one onto the connecting post 7, aligning the tip of the cap with the gap between the weft yarns. Before the release layer material cures, the rigid tube mounting plate is pressed down, causing the rigid tubes to insert into the polyester fabric. After the release layer cures, the connecting post 7 is pulled out of the rigid tube, and the cap is removed by a magnet. The conical design of the cap allows the warp yarns to be separated during insertion, thus preventing yarn breakage.
[0021] The above embodiments one and two can be further improved as follows: even if the weft yarn is wrapped with the weft yarn release layer and the warp yarn is wrapped with the warp yarn release layer, the weft yarn release layer and the warp yarn release layer constitute a release layer.
