[0022] Electronic cloth is a general term for electronic-grade glass fiber cloth used in the electronics industry. The main application of electronic cloth is in the production of copper-clad laminates in the electronics industry. Among conventional electronic cloths, 7628 electronic cloth has a relatively wide range of applications.

[0023] Currently, most of the 7628 electronic fabrics in the prior art are woven using G75 electronic yarn or G37 electronic yarn. Among them, the 7628 electronic fabric woven with G75 electronic yarn has a warp and weft density of 44 × 33 ends / inch and a basis weight of 210 g / m 2 The product quality meets actual needs. However, when G75 electronic yarn is used to weave 7628 electronic fabric, the high production costs result in low weaving efficiency and low profits. The weaving density of 7628 electronic fabrics made with G37 electronic yarns is 22 x 17.1 ends / inch. While G37 electronic yarns can improve production efficiency to some extent, they are prone to deformation and have relatively poor dimensional stability. Furthermore, the yarns are too sparsely spaced in the warp and weft directions, resulting in large gaps between adjacent yarns, which causes the electronic fabric's breathability and other physical properties to exceed standards and make it difficult to meet usage requirements.

[0024] To solve the above problems, the embodiments of this application provide relevant technical solutions, which will be described in detail below.

[0025] According to an embodiment of the present application, an embodiment of a method for manufacturing an electronic fabric is provided, wherein the steps shown in the flowcharts of the drawings may be performed, for example, in a computer system as a set of computer-executable instructions, and although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in a different order than specified herein.

[0037] Specifically, when performing desizing pretreatment, the linear speed of the intermediate dough may be any value within the above-mentioned predetermined linear speed value range, for example, 85 m / min, 105 m / min, or 95 m / min. The temperatures of the first and second high-temperature oven zones may also be any value within the above-mentioned corresponding temperature value range, for example, the temperature of the first high-temperature oven zone may be 420°C, 440°C, or 430°C, and the temperature of the second high-temperature oven zone may be 440°C, 460°C, or 450°C.

[0038] As an optional embodiment, the step of subjecting the intermediate dough to desizing heat treatment comprises a step of subjecting the intermediate dough that has undergone pre-desizing treatment to a first heat retention treatment in a first heat retention temperature zone, wherein the first heat retention temperature zone has a value range of 150 to 200°C and the heat retention time of the first heat retention treatment has a value range of 2 to 3 hours, for example, the first heat retention temperature may be any value within the range of 150 to 200°C, such as 150°C, 200°C, or 180°C, and the heat retention time may be any value within the range of 2 to 3 hours, such as 2 hours, 3 hours, or 2.5 hours; and a step of subjecting the intermediate dough that has undergone the first heat retention treatment to a second heat retention temperature zone, wherein the second heat retention temperature zone has a value range of 220 to 260°C and the heat retention time of the second heat retention treatment has a value range of 5 to 6 hours. and a step of performing a third heat retention treatment on the intermediate dough that has undergone the second heat retention treatment in a third heat retention temperature range, wherein the third heat retention temperature range is 390 to 410°C and the heat retention time range for the third heat retention treatment is 50 to 53 hours, for example, the third heat retention temperature may be 390°C, 410°C, or 400°C as long as it is any value within the range of 390 to 410°C, and the heat retention time for the third heat retention treatment may be 50 hours, 53 hours, or 52 hours as long as it is any value within the range of 50 to 53 hours.

[0039] In some embodiments of the present application, the step of performing a surface chemical treatment on the intermediate substrate includes a step of completing the surface chemical treatment on the intermediate substrate by immersing the intermediate substrate that has completed the desizing heat treatment in a pre-prepared silane coupling agent, wherein the solid content of the pre-prepared silane coupling agent ranges from 0.10% to 0.45%, and in the process of performing the surface chemical treatment on the intermediate substrate, the pH value of the pre-prepared silane coupling agent ranges from 2.0 to 5.0.

[0040] Specifically, when performing a surface chemical treatment on an intermediate material, the solid content of the pre-prepared silane coupling agent may be any value within the range of 0.10% to 0.45%, such as 0.10%, 0.27%, 0.3%, 0.35%, 0.40%, or 0.45%. In addition, in the surface chemical treatment process, the pH value of the pre-prepared silane coupling agent can be controlled to 2.0 to 5.0 by adding an acidic reagent such as glacial acetic acid to the pre-prepared silane coupling agent. For example, the pH value may be any value within the range of 2.0 to 5.0, such as 2.0, 2.5, 3.0, 4.0, 4.5, or 5.

[0041] In an optional embodiment, the step of performing an opening treatment on the intermediate fabric includes a step of passing the intermediate fabric that has completed the surface chemical treatment through a high-pressure water jet to complete the opening treatment on the intermediate fabric and obtain a 7628 electronic fabric, wherein the pressure of the high-pressure water jet is in the range of 0.5 to 4.0 MPa, the nozzle hole diameter of the high-pressure water jet is in the range of 0.1 to 0.2 mm, and the water flow conductivity of the high-pressure water jet is 10 μs / cm or less.

The nozzle hole diameter of the high-pressure water jet may be any value within the above range, such as 0.1 mm, 0.2 mm, or 0.15 mm.

[0043] Through the above steps, the 7628 electronic fabric can be woven using high-open electronic yarn as raw material, thereby ensuring that the basis weight of the 7628 electronic fabric meets the requirements, and effectively reducing the warp and weft density during weaving, improving weaving efficiency, and better meeting market and usage requirements.

[0044] In addition, compared with the 7628 electronic fabric woven with the conventional G75, the 7628 electronic fabric woven with the highly open electronic yarn has a lower warp and weft density, which allows the yarn width to be further increased, filling the gaps between adjacent yarns, reducing the thickness of the electronic fabric, and improving the physical performance of the electronic fabric.

[0045] In addition, in the manufacturing method of electronic cloth provided in the examples of this application, by controlling the temperature, humidity, and twist within a predetermined range when twisting a high-open fiber raw yarn to form a high-open fiber electronic yarn, the twisted high-open fiber electronic yarn has good bundling properties and reduced fuzzing on the yarn surface, resulting in a smooth and clean surface for the woven electronic cloth. By controlling the winding tension after sizing and the winding tension after warp joining within a predetermined range, the weaving shaft has good hardness, ensures good fabric surface flatness, and improves fabric surface tension uniformity. By adopting a specific desizing pretreatment and desizing heat treatment, the adhesive residue on the electronic cloth can be significantly burned off, improving the penetration and compatibility between the surface treatment agent and the electronic cloth. Furthermore, by adopting the surface treatment and opening treatment of the present invention, the high-open fiber electronic yarn in the electronic cloth is fully opened by opening, allowing it to fully contact the surface treatment agent, reducing the thickness of the fabric surface, and the excess surface treatment agent is carried away by a high-pressure water jet, improving the uniformity of bonding of the electronic cloth with the subsequent resin.

The warp density of the electronic fabric is 42.4 ends / inch, the weft density is 30.5 ends / inch, and the basis weight of the electronic fabric is 210 g / m 2 and has a thickness of 169 μm.

[0100] As an alternative embodiment, the manufacturing flow of the 7628 electronic cloth in Example 8 above is as follows:

[0101] Step 1: Select a high-opening electronic yarn, twist the high-opening electronic yarn with a twisting machine to obtain a high-opening electronic yarn, and control the temperature and humidity during twisting of the high-opening electronic yarn to 25°C and 50%, respectively.

[0106] The 7628 electronic fabric and manufacturing method provided in the examples of this application can effectively improve production efficiency and reduce production costs compared to the prior art, while ensuring that the performance of the 7628 electronic fabric meets the requirements. Specifically, the 7628 electronic fabric woven using G37 electronic yarn in the prior art has a warp and weft density of 22 × 17.1 ends / inch and a basis weight of 210 g / m2, as shown in Figure 3. 2 The 7628 electronic fabric woven using G37 electronic yarn has a low warp and weft density and high weaving efficiency, but the dimensional stability of the produced 7628 electronic fabric is low, and the yarn arrangement in the warp and weft direction is too sparse, so the physical properties of the electronic fabric, such as breathability, exceed the standards.

[0107] Compared with the 7628 electronic fabric woven with G75 yarn, the 7628 electronic fabric woven with G75 yarn has a warp and weft density of 44 × 33 ends / inch and a basis weight of 210 g / m², as shown in Figure 4. 2 Although the quality of the 7628 electronic fabric made with G75 yarn meets the requirements, its production efficiency is too low. In this application, the high-opening electronic yarn is used to weave the 7628 electronic fabric, and by ensuring that the quality of the 7628 electronic fabric obtained by weaving meets the requirements, the production efficiency can be effectively improved.

[0108] In summary, the basic parameters of several types of electronic fabrics provided in the examples of the present application and electronic fabrics in the prior art are shown in the table below.

[0109] [Table 1]

[0110] As can be seen from the table above, the high-open electronic yarn provided in the examples of the present application has a higher linear density than G75 electronic yarn, and the yarn is thicker, easier to shape, less expensive, and more convenient to use in weaving.In addition, in the examples of the present application, the traditional G75 electronic yarn is replaced with the high-open electronic yarn to weave the 7628 electronic fabric, which reduces the weaving density, effectively improves weaving efficiency, improves the dimensional stability of the fabric surface, and reduces weaving costs, thereby meeting the increasing demand for electronic fabrics on the market. Furthermore, as can be seen from the table above, when the 7628 electronic fabric is woven using the manufacturing method of the 7628 electronic fabric provided in the examples of the present application, the highly open electronic yarn can be fully opened, so that the warp and weft widths of the electronic yarn are larger than those of the G75 electronic yarn, and the warp and weft width can reach 600 to 750 μm. This can compensate to a certain extent for the increased yarn gaps due to the decrease in the weft and weft density of the electronic yarn, contributing to a reduction in the overall thickness of the 7628 electronic fabric, thereby improving the physical performance of the 7628 electronic fabric.

[0111] Furthermore, compared to the 7628 electronic fabric of the prior art, the commonly available G75 electronic yarn has a median linear density of 69 tex, the median linear density of G37 electronic yarn is 137 tex, and the density of high-open electronic yarn is 72-95 tex. The linear density of G37 electronic yarn is nearly twice that of G75 electronic yarn. Weaving 7628 electronic fabric using G37 can improve weaving efficiency by a factor of two. However, the weaving density is too low, resulting in poor dimensional stability and susceptibility to deformation, making it difficult to ensure the weaving quality of the electronic fabric. The method of weaving 7628 electronic fabric using high-open electronic yarn provided in the embodiments of the present application allows the weaving density of the 7628 electronic fabric to be within an appropriate range, improving weaving efficiency and ensuring the dimensional stability and weaving quality of the electronic fabric.

[0112] As can be seen from the above comparison results, the 7628 electronic fabric woven using the highly open electronic yarn provided in the examples of the present application has superior performance in terms of yarn warp width, warp and weft density, and warp and weft strength compared to the 7628 electronic fabric woven using G75 electronic yarn and G37 electronic yarn in the prior art. This improves the production and weaving efficiency of the 7628 electronic fabric and also improves the physical properties of the 7628 electronic fabric. As a result, the 7628 electronic fabric woven using the highly open electronic yarn has superior performance in terms of breathability, impregnation, etc.

[0113] Specifically, the weaving flow for weaving 7628 electronic fabric using G37 electronic yarn in the related art is as follows:

[0114] Step 1 is to make G37 electronic yarn into warp and weft yarns.

[0115] In step 2, through holes are opened on the outer surfaces of the warp and weft yarns, and then the warp and weft yarns are fed into an air jet loom for weaving.

[0116] In step 3, the cloth woven in step S2 is sequentially fed into a KH unit and a BH furnace for continuous heat treatment and batch heat treatment. When the cloth in step S1 is continuously heat treated using the KH unit, the furnace temperature is 300-400°C, the heating time is 20-30 minutes, and the amount of residual organic matter in the treated cloth is 0.2-0.4%. When the cloth is treated using a BH furnace, the temperature is 380-410°C, the treatment time is 30-50 hours, and the amount of residual organic matter in the treated cloth is 0.02-0.04%.

[0117] Step 4: The heat-treated cloth is sent to a silane coupling agent for surface chemical treatment to obtain electronic cloth. Before using the silane coupling agent to chemically treat the surface of the cloth, a fluorosurfactant needs to be added to the silane coupling agent, and the mass fraction of the fluorosurfactant is 0.5% of the silane coupling agent.

[0118] The following table compares the physical parameters of the 7628 electronic fabric manufactured using the highly open electronic yarn provided in the examples of the present application, the 7628 electronic fabric manufactured using the G37 electronic yarn obtained using the above manufacturing flow, and the 7628 electronic fabric manufactured using the G75 electronic yarn.

[0119] [Table 2]

[0120] The 7628 electronic cloth woven using the highly open electronic yarn provided in the examples of the present application exhibits significantly lower air permeability than the 7628 electronic cloth of the prior art when the basis weight of the electronic cloth is unchanged, and the electronic cloth manufactured using the manufacturing method of the 7628 electronic cloth provided in the examples of the present application exhibits a flatter fabric surface, better uniformity, and a lower fabric surface thickness. Furthermore, the low impregnation of the electronic cloth manufactured using the manufacturing method of the 7628 electronic cloth provided in the examples of the present application indicates that the 7628 electronic cloth provided in the examples of the present application not only has excellent permeability and compatibility with surface treatment agents, but also has better bonding properties with resins.

[0121] As described above, the manufacturing method of the 7628 electronic cloth woven using the high-openness electronic yarn provided in the embodiments of this application rationally controls the temperature, humidity, and twist degree when twisting the high-openness raw yarn to form the high-openness electronic yarn, so that the twisted high-openness electronic yarn has good bundling properties and reduced fuzz on the yarn surface, and the woven electronic cloth has a smooth and neat surface. By rationally controlling the winding tension after sizing and the winding tension after warp joining, the weaving shaft has good hardness, and good flatness of the fabric surface is ensured, improving the uniformity of the fabric surface tension. The electronic cloth is pre-treated by passing it through multiple high-temperature oven zones at a constant linear speed, and then the desizing heat treatment is carried out in a three-stage temperature-insulating manner. The two high-temperature desizing treatments are then used to significantly burn off any residual glue on the electronic cloth, improving the penetration and compatibility between the surface treatment agent and the electronic cloth. The three-stage insulation method also effectively protects the smoothness and cleanliness of the cloth surface, improving the quality of the cloth surface and also favoring the removal of glue from the electronic cloth.

[0122] Furthermore, by using the surface treatment and opening treatment methods provided in the examples of this application, the 7628 electronic cloth is immersed in a silane coupling agent to strengthen the bond between the electronic cloth and the resin during subsequent processing, and the acidity is adjusted with glacial acetic acid to favor hydrolysis when using the silane coupling agent. The highly open electronic yarns in the electronic cloth are then fully opened by opening, fully contacting the surface treatment agent, reducing the thickness of the cloth surface, and the excess surface treatment agent is removed by high-pressure water, effectively improving the uniformity of the subsequent bonding of the electronic cloth with the resin.

[0123] In the opening process, the present embodiment controls the pressure of the high-pressure water jet to ensure that the highly opened electronic yarn is sufficiently opened and flattened, while avoiding excessive pressure that could cause the highly opened electronic yarn to fluff and break. Here, in the present embodiment, controlling the conductivity of the water jet to <10 μs / cm can reduce impurities on the fabric surface and improve the bonding strength of the electronic fabric.

[0124] In the above embodiments of the present application, the description of each embodiment has its own emphasis, and for parts not described in detail in one embodiment, reference can be made to the relevant descriptions of other embodiments.

[0125] In some embodiments provided herein, it should be understood that the disclosed technical content may be implemented in other ways.
