Description

Adhesive braiding net and binding net

Technical Field

The utility model relates to the technical field of netting, in particular to an adhesive netting and a binding net.

Background

In agricultural production, it is common to bind straw, pasture with a disposable elastic net, which is commonly referred to as a grass binding net, also referred to as a grass wrapping net. The grass-binding net is required to meet certain strength requirements, and on the basis, the gram weight needs to be reduced as much as possible, because the production cost is directly related to the gram weight.

Most of the current grass binding nets are woven and formed by a warp knitting machine, and the production efficiency is high. The structure of the grass bundling net is characterized by larger meshes and certain bearing strength. The grass tying net shown in fig. 1 comprises a plurality of warp chains which are parallel along the warp direction, each warp chain is formed by connecting chain links formed by winding warp yarns in a loop in series, and weft insertion is arranged between two adjacent warp chains along the weft direction, so that a net structure is formed. Because of the warp knitting structure, loop structures are arranged between the loop links in each warp chain and between the weft insertion and the loop links, the whole net structure has no knots, is a knotless net, and avoids knots and strength loss.

Although this construction avoids knotting, there is a 30% -40% loss of strength when stressed due to the constant winding and looping of the warp threads. To avoid this, the prior art improves on this structure by incorporating warp inserts in the warp chain, as shown in fig. 2, which are distributed in a straight line, thereby increasing the warp strength, as described in the patent: the warp-direction chain-woven structure of a backing for a woven net and a grass tying net (application number 202010029976.7) using the same are described in detail.

This technique is also described in U.S. patent publication No. US20200385902 A1.

After the warp lining is added, although the strength is increased, because the warp threads and the warp lining exist at the same time, under the condition that the quality of the grass tying net is certain, the denier of the warp threads and the warp lining need to be strictly controlled, otherwise, even if the strength is improved, the production cost is also improved due to the increase of the whole weight, and the practical application possibility is lower.

Therefore, aiming at the current netting for binding, how to improve the strength of the netting without increasing the gram weight is a technical innovation difficult problem faced by the industry.

Detailed Description

For a further understanding of the present utility model, the present utility model will be described in detail with reference to the drawings and examples.

The structures, proportions, sizes, etc. shown in the drawings are shown only in connection with the present disclosure, and are not intended to limit the scope of the utility model, since any modification, variation in proportions, or adjustment of the size, etc. of the structures, proportions, etc. should be considered as falling within the spirit and scope of the utility model, without affecting the effect or achievement of the objective. Also, the terms "upper", "lower", "left", "right", "middle", and the like are used herein for descriptive purposes only and are not intended to limit the scope of the utility model for modification or adjustment of the relative relationships thereof, as they are also considered within the scope of the utility model without substantial modification to the technical context.

Fig. 1 shows a schematic view of a prior art grass-binding net, in which warp chains 1 are arranged in parallel and the warp chains 1 are connected by weft insertion 2, which structure results in a reduced strength due to the windings of the warp yarns in the warp chains.

Fig. 2 shows an improved grass-binding net structure, as an improvement, a lining warp 003 is added in a warp chain 001, the lining warp 003 adopts a linear structure, and no knot or winding is performed, so that no direct knot exists, and main pulling force can be provided in the warp direction.

The lining warp adopting the linear structure can increase the strength, but is connected with the lining weft, so the lining warp also needs to be matched with the warp of the winding for connecting different warps, and the warp is prevented from moving after weaving.

Example 1

Referring to fig. 3, an adhesive netting of the present embodiment includes warp yarns 1 and weft yarns 2, wherein the warp yarns 1 are arranged in parallel along the warp direction, the weft yarns 2 are distributed between two adjacent warp yarns 1 in a zigzag manner, and the intersections of the warp yarns 1 and the weft yarns 2 are connected by bonding; and the stretching rate of the warp yarn 1 in the netting is 30-80%.

The distance between two parallel warp yarns 1 can be controlled within a certain range, and the difference of the root packaging materials can be adjusted, and the distance can be generally set between 1 cm and 12cm, for example, 3.0cm, 6.2cm, 8.4cm and the like are adopted. Warp yarn 1 here does not refer to a single film yarn, but in some embodiments, warp yarn 1 may be formed by twisting multiple yarns.

The weft yarns 2 in this embodiment mainly serve as a connecting function, so that the warp yarns 1 are connected into a whole. The weft yarns 2 are in this embodiment zigzag distributed between two adjacent warp yarns 1.

In this embodiment and other embodiments, the zigzag pattern refers to an overall pattern formed by alternately spacing the weft yarns 2 from left to right in the warp direction, or the zigzag pattern is formed by alternately forming the weft yarns from left to right and the warp yarns together, and the zigzag end is not required to be triangular or trapezoidal. As shown in fig. 3, the end of the device forms a fulcrum angle, and the angle is a sharp angle; it is also possible to have a structure as shown in fig. 5, in which the fulcrum angle is a trapezoid-like structure. Furthermore, the form shown in the figures is determined according to the state of the process, in the actual product, since both the warp yarn 1 and the weft yarn 2 are flexible materials, the fulcrum-folded corner portions thereof are generally free and loose in a deformed state, for example, formed in an arc shape, and should be considered to be saw-tooth-shaped as a whole, without positioning.

In addition, since the weft yarn is saw-toothed and reciprocates left and right within a short distance in the embodiment, the weft yarn is shaped by a fulcrum, and the weft yarn changes direction at the fulcrum during processing, so that a fulcrum folding angle is formed.

In this embodiment, the junction between the warp yarn 1 and the weft yarn 2 is bonded, for example, during processing, a hot melt adhesive is first placed on the warp yarn 1 or the weft yarn 2 at a fixed point, and then bonded by heating or hot pressing, or directly bonded by other methods without heating.

Warp yarn 1 and weft yarn 2 may be made of polyethylene or polypropylene or a mixture of polyethylene and polypropylene, and are formed into a film by a film forming process and then cut into filaments to form yarns. Since the tensile strength and the elasticity are in an opposite relationship under certain conditions, the finished product of the netting needs to bear a larger pulling force when in use, and in order to ensure the strength, the stretching ratio of the warp yarn 1 is limited to 30% -80%, for example, 32% -40%,45% -55%,56% -62% and 65% -80%.

The elongation referred to in the present utility model is the ratio of the length that is increased by stretching to the original length when the yarn is stretched and broken. Because netting is generally used under the condition of low bearing weight, the netting needs to have certain stretching rate and strength at the same time. If the effect of heating on the yarn is neglected in order to achieve thermal bonding, this results in insufficient strength, and therefore a stretch ratio of warp yarn 1 between 30% and 80% after bonding into a net is required. More preferably between 45% and 70%.

Example 2

Fig. 4 shows a specific embodiment in which warp yarns 1 are arranged in parallel and weft yarns 2 are arranged in a zigzag pattern between two adjacent warp yarns 1, the ends of the weft yarns 2 forming a fulcrum angle 3, the ends of the fulcrum angle being connected to the warp yarns 1.

With this structure, it is necessary to pass the warp yarn 1 between both side lines of the fulcrum angle, and to bring the end of the fulcrum angle into contact with the upper and lower surfaces of the warp yarn 1. The mode can be used for bonding during knitting by using a dispensing process, or knitting and laying wires first and then bonding by heat.

The thermal bonding can be directly and locally melt-bonding the warp yarn 1 and the weft yarn 2 by adopting a heating mode, namely, bonding the warp yarn 1 and the weft yarn 2 together by locally heating at fixed points, or bonding by adopting a hot melt adhesive mode.

Example 3

As another embodiment of fig. 4, warp yarns 1 are arranged in parallel, weft yarns 2 are distributed between two adjacent warp yarns 1 in a zigzag manner, the end parts of the weft yarns 2 form fulcrum folded angles 3, two side lines of the fulcrum folded angles 3 of the weft yarns 2 are laid on the same side of the warp yarns 1, and the top end parts of the fulcrum folded angles 3 and the warp yarns 1 form a connecting point.

For specific bonding means reference may be made to other embodiments. In order to realize the processing of the netting structure of this embodiment, it is necessary to set the fulcrum to catch the weft yarn 2, and then connect the warp yarn 1 and the weft yarn 2 by bonding, so that a fulcrum angle 3 protruding from the warp yarn 1 is inevitably formed at the end. With only one connection point, the fulcrum angle 3 is bonded with the warp yarn 1, and no gap is formed between the fulcrum angle 3 and the warp yarn 1. This allows the fulcrum to support a portion of the weft yarn, avoiding gaps, and also allows the gap between the fulcrum fold and the warp yarn to be removed during bonding.

Example 4

Fig. 3 shows another embodiment, in which the fulcrum angle 3 of the weft yarn 2 in fig. 3 protrudes from the warp yarn 1 in the weft direction and forms two connection points at the junction with the warp yarn 1, and a certain gap is formed between the fulcrum angle 3 and the warp yarn, and after bonding, a closed fulcrum ring is formed. The fulcrum ring can be formed by weft yarns, or can be formed by surrounding warp yarns and weft yarns. When the fulcrum is thin, the gap in the closed loop may be small, and may be less than 1mm.

The bonding net knitting process and the knitting process have larger difference, the knitting can be directly looped for knitting, and the weft yarns are connected through the nodes. However, in the bonding process of the present utility model, since it is required to avoid knotting of the warp yarn, the weft yarn 2 is not easily shaped, and thus the yarn may be laid first for shaping when the knitting process is performed.

In order to realize the processing of the netting structure of this embodiment, it is necessary to set the fulcrum to catch the weft yarn 2, and then connect the warp yarn 1 and the weft yarn 2 by bonding, so that a fulcrum angle 3 protruding from the warp yarn 1 is inevitably formed at the end. In order to simplify the process, the fulcrum is arranged outside the warp yarn in the embodiment, the weft yarn can turn around the fulcrum, and because the warp yarn also moves synchronously and can walk for one end distance, two intersecting points are formed between the warp yarn 1 and the weft yarn 2, and after bonding connection, the warp yarn and the weft yarn between the two connecting points form a closed loop, namely a fulcrum loop.

The two intersections between warp yarn 1 and weft yarn 2 may be one integral bonding point or two independent bonding points when bonded together.

As shown in fig. 3, the fulcrum fold 3 is proximate to warp yarn 1, and when spot gluing is used, only one point of attachment can be used to bond two attachment point locations. If the distance between the two connection points is large, the two connection points can be respectively bonded.

Example 5

Fig. 5 shows another embodiment, in which two warp yarns 1 are laid on the same side of the side line of the fulcrum angle 3, the saw tooth portions of the warp yarns 1 and the weft yarns 2 form two connection points, the distance between the two connection points is larger, the distance between the two connection points can be 2-8mm, and a closed loop is formed between the weft yarn section corresponding to the fulcrum angle 3 and the warp yarns 1 at the position of 2-8mm.

When the spacing is larger, if one fulcrum is used to position warp yarn 1, a larger lateral distance is created in the weft direction, resulting in more weft yarn 2 residue. As shown in fig. 6, the fulcrum Q is spaced a greater distance from the yarn, forming a triangle, with more excess material. When the supporting point A and the supporting point B are matched, a trapezoid is formed, the length of the residual material is equivalent to that of the interval, and the waste of materials can be avoided.

It should be noted that, no matter a single fulcrum or two fulcrums are adopted, the state of the processed netting is that part of weft yarn 2 exists at the edge of warp yarn 1, the part of weft yarn 2 is the rim charge left when the fulcrum shapes the weft yarn during processing, the processed weft yarn is in a relatively loose state, and the processed weft yarn is not required to be in a triangle or trapezoid structure, and can also be in an arc-shaped bulge and other structures.

Example 6

Fig. 7 shows another embodiment in which warp yarn 1 comprises 1-4 warp direction arranged sub-yarns, and when there are more than 2 sub-yarns, a plurality of sub-yarns are arranged side by side in the weft direction.

When there is only one sub-yarn, warp yarn 1 is the sub-yarn. When there are more than 2 sub-threads arranged at intervals, warp yarn 1 in this embodiment is constituted together. Preferably, the sub-lines may have a pitch of 1-3mm therebetween.

Example 7

By way of further limitation to warp yarn, warp yarn 1 is a yarn of 600-1200 denier, such as 700 denier, 800 denier, 1000 denier, preferably high density polyethylene film yarn.

The distance between two adjacent warp yarns 1 can be controlled between 1 and 8cm, and further can be between 2 and 6cm, such as 4.0cm, 5.2cm, 6.0cm.

In the above embodiments, the weft yarns 2 are arranged in an array in the same state, and in other embodiments, two adjacent weft yarns 2 may be symmetrically distributed.

Example 8

As an embodiment, the adhesive netting in this example includes warp yarn 1 and weft yarn 2, warp yarn 1 is arranged in parallel along the warp direction, weft yarn 2 is distributed between two adjacent warp yarns 1 in a zigzag manner, and the intersection point of warp yarn 1 and weft yarn 2 is connected by thermal bonding.

Specifically, warp yarn 1 and weft yarn 2 adopt polyethylene film yarn, and are connected through glue-free thermal bonding. The polyethylene film yarn exhibits melt viscosity at a certain temperature, and can be bonded together between the warp yarn 1 and the weft yarn 2 by a certain pressure. The processing is easier without adding extra adhesive. Warp yarn 1 stretch is limited to 45% -68%. The elongation of weft yarn 2 is 45% -90%.

Preferably, the elongation of weft yarn 2 is not less than the elongation of warp yarn 1. The weft yarn 2 mainly takes over the weft connection and may have a relatively large stretch.

As other embodiments, the polyethylene film yarn may be used for warp yarn 1, and other materials with similar characteristics may be used for weft yarn 2. For example, warp yarn 1 is polyethylene or polypropylene film yarn, and weft yarn 2 is polypropylene film yarn; or the warp yarn and the weft yarn are monofilament yarns made of a mixed material of polyethylene and polypropylene.

The sub-yarns and the weft yarns 2 adopt polyethylene film yarn, the stretching rate of the sub-yarns is 35% -65%, and the stretching rate can be further limited to 45% -58%. The elongation of the weft yarn 2 is 40% -80%.
