Surface layer and fabric

Abstract

The utility model relates to a surface layer and a fabric. The surface layer comprises a first line, a second line and a wrapping layer. The second wire and the first wire are arranged in a winding mode, and a gap is formed between the first wire and the second wire. The wrapping layer wraps the first wire and / or the second wire, and at least part of the wrapping layer extends to the gap. Based on the arrangement, the wrapping layer is at least partially covered in the gap, so that a foreign object is blocked by the wrapping layer when the foreign object wants to extend into the surface layer through the gap, and the foreign object is not easy to enter the gap. Namely, the arrangement can reduce the possibility that the surface layer is snagged, so that the possibility that fine fluff or fibers appear on the surface of the surface layer is reduced.

Description

TECHNICAL FIELD

[0001] The present application relates to the field of fabric, in particular to a face layer and fabric. BACKGROUND

[0002] Generally, a fabric is composed of many layers, which includes a middle layer in the middle and a face layer on the outside. It is known that the fabric directly contacted with the outside world is the face layer on the outside, so the quality of the outside face layer needs to be guaranteed.

[0003] However, there are often gaps between the threads on the outside face layer, and these gaps can allow foreign objects to enter the face layer when they contact the outside face layer, causing the face layer to be snagged. This further causes small lint or fibers to appear on the surface of the face layer, making the entire face layer no longer smooth and flat. Moreover, snagging can cause the local strength of the face layer to decrease, making it easy to tear or break. Long-term snagging can cause the face layer to gradually lose its original structure and toughness, shortening its service life. Therefore, the snagging problem needs to be addressed to protect the fabric. CONTENT OF THE UTILITY MODEL

[0048] The technical solutions in the embodiments (or, implementations) of the present application will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated.

[0049] If the present embodiments involve directional indications or positional relationships (such as up, down, left, right, front, back, inner, outer, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships, movement conditions, etc. between components in a certain specific posture (as shown in the drawings); if the specific posture changes, the directional indications or positional relationships also change accordingly. In addition, the terms “first”, “second”, etc. in the present embodiments are only used for convenience of description, and cannot be understood as indicating or implying relative importance.

[0050] Reference Figure 1 As shown, the fabric 10 is usually composed of many layers, which include an intermediate layer 200 in the middle and a surface layer 100 on the outside. The intermediate layer 200 here can be one layer or multiple layers, which is not limited by the present application. Meanwhile, the intermediate layer 200 here can be selected according to the needs, such as a waterproof and breathable film, or a thermal insulation film, etc., which is also not limited by the present application.

[0051] From Figure 1 It can be learned that the surface layer 100 on the outside is directly in contact with the outside world. However, referring to Figure 2As shown, there will be gaps 160 between the lines on the surface layer 100, and these gaps 160 will allow foreign objects to enter the surface layer 100 when the surface layer 100 is contacted, thereby causing the surface layer 100 to be snagged. Further, small fluff or fibers will appear on the surface of the surface layer 100, making the entire surface layer 100 no longer smooth and flat. Moreover, snagging will cause the local strength of the surface layer 100 to decrease, making it easy to tear or break. Long-term snagging will cause the surface layer 100 to gradually lose its original structure and toughness, shortening its service life.

[0052] The present application provides a surface layer 100, as shown in Figure 2 and Figure 3 The surface layer 100 includes a first line 110, a second line 120, and a wrapping layer 130. The second line 120 is wound around the first line 110, and there is a gap 160 between the first line 110 and the second line 120. The first line 110 and the second line 120 can be made of nylon fiber (polyamide fiber), which has high tensile strength and good elasticity, making it suitable for making elastic textiles. At the same time, the fiber also has excellent wear resistance, making it suitable for making wear-resistant textiles. Moreover, the fiber can still maintain good physical properties at high temperatures, making it suitable for making textiles in high-temperature environments. Of course, the first line 110 and the second line 120 can also be made of other materials, such as viscose fiber, spandex fiber, or a combination of these fibers. The wrapping layer 130 can be made of polyethylene fiber, which has good wear resistance and improved coolness. In addition, the polyethylene fiber can melt at a certain temperature to cover the gap 160.

[0053] As shown in Figure 3 The wrapping layer 130 covers the first line 110 and / or the second line 120, and at least part of the wrapping layer 130 extends to the gap 160. That is, the wrapping layer 130 can cover the first line 110 alone, or cover the second line 120 alone. Alternatively, the wrapping layer 130 covers both the first line 110 and the second line 120.

[0054] As shown in Figure 4 , Figure 5 , Figure 8 and Figure 9 When starting to weave the surface layer 100, the wrapping layer 130 can be formed into the shapes shown in the figures with the first line 110 and the second line 120, that is, the wrapping layer 130 covers the first line 110 or the second line 120 inside. After the surface layer 100 is woven, it is heated to form Figure 6 , Figure 7 , Figure 10 and Figure 11The shape shown is that the wrapping layer 130 melts and spreads to its edges. Of course, the shape shown after melting is only one of the forms, which can vary according to different temperatures, pressures and external forces, as long as it can extend to the gap 160 after melting, which is within the scope of protection claimed in the present application.

[0055] Based on the above arrangement, the wrapping layer 130 is at least partially covered in the gap 160, so that the foreign matter is blocked by the wrapping layer 130 when it wants to extend into the surface layer 100 through the gap 160, and it is not easy to enter the gap 160. That is, the above arrangement can reduce the possibility of the surface layer 100 being hooked, and further reduce the possibility of fine fluff or fiber appearing on the surface of the surface layer 100.

[0056] In the present embodiment, when the wrapping layer 130 is wrapped on the first wire 110, the wrapping layer 130 is at least partially covered to the outer layer of the second wire 120 and is arranged in connection with the second wire 120. Alternatively, when the wrapping layer 130 is wrapped on the second wire 120, the wrapping layer 130 is at least partially covered to the outer layer of the first wire 110 and is arranged in connection with the first wire 110; or when the wrapping layer 130 is wrapped on the first wire 110 and the second wire 120, the wrapping layer 130 on the first wire 110 is arranged in connection with the wrapping layer 130 on the second wire 120. That is, whether the wrapping layer 130 is arranged only on the first wire 110 or the second wire 120, or the wrapping layer 130 is arranged on the first wire 110 and the second wire 120, the wrapping layer 130 can be covered to the first wire 110 and the second wire 120.

[0057] Based on the above arrangement, the first wire 110 and the second wire 120 can be fixed to each other, thereby enhancing the overall firmness of the surface layer 100 and increasing its durability. In addition, the gap 160 between the first wire 110 and the second wire 120 is also at least partially blocked, thereby reducing the possibility of the foreign matter entering the surface layer 100 through the gap 160 to make the surface layer 100 be hooked.

[0058] It is found through experiments that, when the wrapping layer 130 is wrapped on the first line 110 or the second line 120, if the volume ratio of the wrapping layer 130 to the first line 110 or the second line 120 is too small, the wrapping layer 130 cannot be covered on the adjacent first line 110 or second line 120 in the subsequent melting process. If the volume ratio of the wrapping layer 130 to the first line 110 or the second line 120 is too large, the material of the wrapping layer 130 is too much, and thus the thickness of the surface layer 100 is too large. In the embodiment, the volume ratio of the wrapping layer 130 to the first line 110 or the second line 120 is set to be greater than or equal to 1 / 2 and less than or equal to 2. Within the range, on the one hand, the wrapping layer 130 can be covered on the adjacent first line 110 or second line 120, and on the other hand, the thickness of the surface layer 100 can be prevented from being too large. For example, the volume ratio of the wrapping layer 130 to the first line 110 or the second line 120 can be set to 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0.

[0059] Similarly, when the wrapping layer 130 is wrapped on the first line 110 and the second line 120 at the same time, if the volume ratio of the wrapping layer 130 to the first line 110 and the second line 120 is too small, the wrapping layer 130 cannot be covered on the adjacent first line 110 and second line 120 in the subsequent melting process. If the volume ratio of the wrapping layer 130 to the first line 110 and the second line 120 is too large, the material of the wrapping layer 130 is too much, and thus the thickness of the surface layer 100 is too large. In the embodiment, the volume ratio of the wrapping layer 130 to the first line 110 and the second line 120 is set to be greater than or equal to 1 / 4 and less than or equal to 1. For example, the volume ratio of the wrapping layer 130 to the first line 110 and the second line 120 can be set to 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, 1.0.

[0060] Of course, under the above embodiment, adjustments can be made based on the above structure. For example, the wrapping layer 130 is wrapped in part of the surface layer 100 to improve the strength of the part. Alternatively, when the wrapping layer 130 is wrapped on the first line 110 and the second line 120, only a part of the first line 110 and the second line 120 is wrapped, for example, 1 / 4, 1 / 3, 1 / 2, as long as the wrapping layer 130 is arranged on the first line 110 and the second line 120, it should be within the protection scope of the present application.

[0061] In an embodiment, with reference to Figure 2 and Figure 3As shown, the surface layer 100 includes an edge line area 140, which is formed by the first line 110 or the second line 120 alone. In actual use of the fabric, the first line 110 and the second line 120 will entangle and generate internal tension, which will cause the first line 110 or the second line 120 in the edge line area 140 to be pulled to form curling.

[0062] In this embodiment, the first line 110 or the second line 120 in the edge line area 140 is covered by the wrapping layer 130. In this way, the weight of the edge line area 140 can be increased, and the curling degree of the edge line area 140 can be reduced.

[0063] In an embodiment, referring to Figure 2 and Figure 3 As shown, the first line 110 or the second line 120 in the edge line area 140 is wrapped to form a plurality of protruding units 150. The plurality of protruding units 150 includes first gap units 141 between the plurality of protruding units 150, and second gap units 142 inside the plurality of protruding units 150. As shown, the areas of the first gap units 141 and the second gap units 142 in the edge are larger than the area of the gap 160 in the middle position.

[0064] In this embodiment, the wrapping layer 130 is arranged on the first line 110 or the second line 120, and the wrapping layer 130 extends to the first gap units 141 or the second gap units 142. In this way, on the one hand, the space of the first gap units 141 and the second gap units 142 can be reduced, and the possibility of the surface layer 100 being hooked can be reduced. On the other hand, the wrapping layer 130 can enhance the strength of the first line 110 or the second line 120, so that the first line 110 or the second line 120 in the edge line area 140 is not easy to be pulled off.

[0065] In an embodiment, referring to Figure 3 As shown, the wrapping layer 130 on the plurality of protruding units 150 is arranged to be connected to the wrapping layer 130 on the adjacent protruding units 150 through the first gap units 141. That is, the plurality of protruding units 150 are connected and fixed to each other by the wrapping layer 130. In this way, the plurality of protruding units 150 in the edge line area 140 can form a whole, so that when one of the plurality of protruding units 150 is hooked, several protruding units 150 near it can also exert tension, so that it will not be directly hooked by small fluff or fiber.

[0066] In an embodiment, continuing to refer to Figure 3As shown, the wrapping layer 130 on the plurality of raised units 150 is arranged to close the second gap unit 142. That is, the space inside the raised unit 150 is entirely covered by the wrapping layer 130. Based on the above arrangement, foreign objects cannot enter the raised unit 150 through the second gap unit 142, so as not to hook the raised unit 150, thereby making the first thread 110 and the second thread 120 on the edge line area 140 stable.

[0067] Based on the above arrangement, in the present embodiment, the wrapping layer 130 on the plurality of raised units 150 is arranged to close both the first gap unit 141 and the second gap unit 142. In this way, on the one hand, the plurality of raised units 150 on the edge line area 140 can form a whole, so that when one of the raised units 150 is hooked, the several raised units 150 near it can also exert a pulling force, so as not to be directly hooked by the fine fluff or fiber. On the other hand, foreign objects cannot enter the raised unit 150 through the second gap unit 142, so as not to hook the raised unit 150, thereby making the first thread 110 and the second thread 120 on the edge line area 140 stable. Figure 3

[0068] In an embodiment, the above fabric 10 can further be provided with a fastening thread 300, which is arranged through the intermediate layer 200 and the surface layer 100, for fixing the intermediate layer 200 and the surface layer 100 to each other, and the wrapping layer 130 is wrapped on the fastening thread 300, and at least part of the wrapping layer 130 is arranged between the intermediate layer 200 and the surface layer 100.

[0069] Similarly, when the fastening thread 300 is arranged through the intermediate layer 200 and the surface layer 100, the wrapping layer 130 wrapped on the fastening thread 300 can be melted by heating, so as to be fixed to the intermediate layer 200 and the surface layer 100, thereby making it more stable.

[0070] In addition, the present application can also use customized 42-inch 36-needle and 46-inch 36-needle circular knitting machines, and select 75D first thread 110 and 70D second thread 120 for interweaving. Moreover, the first thread 110 and the second thread 120 are respectively made of PE fiber and nylon fiber with high specific heat capacity as raw materials, so as to improve the coolness value.

[0071] Under the above arrangement, the double-reverse stitch organization makes the fabric longitudinally shortened due to the inclination of the loops, thereby increasing the longitudinal density and thickness of the fabric. Moreover, the double-reverse stitch organization has great extensibility and elasticity when stretched in the longitudinal direction. When the external force is removed, the characteristics of returning to the original state are good. In addition, the double-reverse stitch organization of the above arrangement basically does not produce the situation of rolling edge.

[0072] ​Based on the above setting, the ratio between the first line 110 and the second line 120 is set to 1:1, the second line 120 is dyed, and the net color effect is achieved. And the direct contact surface has 50% first line 110 and wrapping layer 130, which improves the cool value. The dyeing stability is set at 90 degrees, the low temperature dyeing process, reduces the speed in the cylinder, reduces the friction of the wrapping layer 130 fiber, and further reduces the loss.

[0073] In actual test, the cool value is improved, and the detection result is 0.46 under the detection method of Japan standard, which is greatly improved compared with the previous cool fabric. At the same time, due to its special structure, the hand feeling is improved, and the hooking phenomenon is reduced. In addition, the difference between polyethylene fiber and nylon fiber on the structure, the overall air permeability is obviously improved compared with the silk ammonia fabric.

[0074] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of the present application is not limited to the precise structure described in the above embodiments and shown in the drawings; any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the scope of protection of the present application.
