Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items. In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Fig. 3 is a heat-shrinkable protective sleeve according to an embodiment of the present invention. As shown in fig. 3, the heat shrinkable protective sleeve has a double-layer structure including an inner sleeve layer 200 and an outer sleeve layer 100.
The inner layer and the outer layer of the sleeve are connected double-layer structures woven in a preset chain arrangement and drafting mode. According to the requirement of actual conditions, the sleeve can be obtained by knitting different yarn materials on the inner layer and the outer layer of the sleeve.
It should be noted that although the specification discloses only a two-layer construction of the heat shrinkable protective sleeve. However, based on the inventive idea disclosed in the embodiments of the present invention, the skilled person can also adjust the flower chain arrangement to weave a heat-shrinkable protective sleeve with more layers.
In some embodiments, the thickness of the heat-shrinkable protective sleeve of the double-layer connecting structure can be controlled to be greater than or equal to 1.6 mm. Preferably, the thickness of the thermal shrinkage protective sleeve can be controlled to be 2.5mm, so that the thickness of the product is increased, and the impact resistance of the product is improved.
In other embodiments, the proper yarn can be further selected to meet the performance requirements of actual use. Wherein the yarn material is 900D polyester yarn.
By using a thicker 900D interlaced yarn, the inner layer thickness and softness can be increased to improve impact resistance.
It should be noted that when further improvement of the impact resistance is desired, this can also be achieved by further increasing the thickness and using a higher strength yarn material.
Preferably, in order to improve the wear resistance, a post-treatment sizing process can be further added to the heat-shrinkable protective sleeve.
The specific post-treatment sizing process can comprise the following steps: firstly, the irradiated finished product is soaked and passed through from the vinegar-acrylic solution. Then, the soaked finished product is primarily extruded by a compression roller and then is sent into a high-temperature oven (the temperature is 150 ℃ and 320 ℃, and the machine speed is more than 500m/H) to pass through. And finally, drying and shaping by a high-temperature oven to form a uniform adhesive film on the surface of the film.
In some embodiments, the vinyl acetate-acrylic aqueous solution can be obtained by mixing water and vinyl acetate-acrylic emulsion in a one-to-one ratio, and in equal proportions.
Besides the vinegar-acrylic solution, other glue or two auxiliary agents can be used in a matching mode to improve the wear-resisting, heat-preserving and/or impact-resisting performance of the heat-shrinkable protective sleeve.
It should be noted that when further improvement of wear resistance is required, it can also be achieved by increasing the thickness of the heat-shrinkable protective sleeve, making the yarn more highly wear-resistant (such as nylon aramid or other mixture of fibers) and/or increasing the concentration of the vinyl acetate solution to increase the thickness of the surface film of the finished product.
In some embodiments, the warp and weft densities of the heat shrinkable protective sleeve may be increased to 50 and 17, respectively, to increase the density of the heat shrinkable protective sleeve.
When the thickness and the density of the thermal shrinkage protective sleeve are increased, a compact layer can be formed during thermal shrinkage, and therefore the technical effect of improving the heat preservation performance of the product is achieved. Preferably, a heat insulating material (such as ceramic fiber with low thermal conductivity) can be added or a heat insulating glue can be dip-coated to further improve the heat insulating performance.
Fig. 1 is a schematic diagram of a flower chain arrangement manner provided in the embodiment of the present invention. Fig. 2 is a schematic view of a threading manner provided in the embodiment of the present invention. Based on the lace arrangement mode and the threading mode shown in fig. 1 and fig. 2, the woven belts with the connected double-layer structure can be obtained by weaving through a weaving machine, so that the heat-shrinkable protective sleeve of the embodiment of the invention is obtained.
In this embodiment, two different pan heads (e.g., 2-by-one/1-by-one) are used so that the inner and outer sleeve layers can be braided from different yarn materials.
Therefore, on the premise of meeting the requirements of wear resistance, impact resistance and heat insulation resistance, technicians are allowed to select corresponding material combinations according to different working conditions so as to achieve the effects of reducing the material consumption and the cost.
The chain is a chain with pattern plates and can be used for controlling the motion track of the heald frame. Through the movement of the heald frame and the flower chain, the warp and weft can be crossed, floated and sunk according to a set rule, and are interwoven to form a target fabric.
In a fabric, the point at which the warp and weft threads intersect may be referred to as a "stitch point". According to the difference of the relative position relationship of the longitude and latitude, the method can be divided into two types of high (indicated by X in figure 1) and low (indicated by O in figure 1). Wherein "high" indicates the weave point of the warp yarn over the weft yarn and "low" indicates the weave point of the warp yarn under the weft yarn.
As shown in fig. 1, 8 flower chain circulation units, numbered 1-8, are included. The flower chains 1 to 6 are used for weaving the outer layer of the sleeve, and the flower chains 7 to 10 are used for weaving the inner layer of the sleeve.
As shown in fig. 2, the heat-shrinkable protective sleeve is composed of a lock side, a selvage side, and a middle repeated arrangement portion between the lock side and the selvage side. The outer sleeve layer may include an upper outer layer and an upper inner layer, and the outer sleeve layer may include a lower inner layer and a lower outer layer.
Specifically, on the heddle pieces of the heald frames numbered 1-6, each piece passes through two 900D yarns, and on the heddle pieces of the heald frames numbered 7-10, each piece passes through one 900D yarn and is used for weaving the corresponding sleeve inner layer and the sleeve outer layer respectively.
Through the arrangement of the flower chains and the threading mode, the special fabric with the connected double-layer structure can be woven.
In conclusion, the heat-shrinkable protective sleeve provided by the embodiment of the invention is of a connected double-layer structure, can play a good wear-resistant protection role when the automobile rubber tube or the wire harness has friction interference, and can prevent the wire harness or the rubber tube from being worn out and play a protection role when the wire harness or the rubber tube and other parts are contacted and rubbed with each other due to vibration in the driving process of an automobile.
The polyester multifilament yarn with thick thickness and low thermal conductivity is used. After thermal shrinkage, the final inside diameter can be reduced to 1/2 of the original inside diameter, so that the thickness and the degree of compactness are enhanced, and the heat dissipation of the parts needing to be insulated can be reduced.
Furthermore, the double-layer structure formed by the high-strength yarns with the large D number is used, and the thickness is thick, so that the protected parts can be effectively protected when the automobile is impacted, and the anti-impact effect is achieved.
Compared with the common non-linked hollow double-layer structure, the connected double-layer structure obtained by the weaving method has smoother and more attractive appearance after thermal shrinkage, and simultaneously effectively solves the problem of port scattering.
In addition, the wear resistance can be further improved by a mode of dip-coating the vinyl acetate-acrylic latex after irradiation to form a uniform transparent adhesive layer on the surface. Meanwhile, the linking effect of the adhesive layer can also help to improve the problem of port opening scattering.
It should be understood that the technical solutions and concepts of the present invention may be equally replaced or changed by those skilled in the art, and all such changes or substitutions should fall within the protection scope of the appended claims.
