Description

TECHNICAL FIELD

[0001] The application relates to the technical field of textile fabrics, in particular to a nylon-polyurethane sandwich fabric. BACKGROUND

[0002] The sandwich fabric is a kind of fabric interwoven by two or more layers of yarns, which is more compact than ordinary gauze and thus more solid. Due to its double or multi-layer structure, the sandwich fabric can provide better warmth retention. The nylon-polyurethane sandwich fabric is an elastic fabric combining nylon and spandex, which has excellent elasticity and wear resistance.

[0003] Although the sandwich fabric is interwoven by multiple layers of yarns to improve its warmth retention, with the increase of the number of layers, the thickness and weight will also increase, which will affect the freedom of movement after wearing the corresponding clothes and cause a certain burden. Therefore, further improvement is needed. CONTENT OF THE UTILITY MODEL

[0004] In order to reduce the weight of the fabric while maintaining good warmth retention, the application provides a nylon-polyurethane sandwich fabric.

[0005] The application provides a nylon-polyurethane sandwich fabric, which adopts the following technical scheme:

[0006] The nylon-polyurethane sandwich fabric comprises a plurality of base cloth layers, the yarns in the adjacent two base cloth layers are interwoven, the yarns in the base cloth layers comprise a yarn core and an outer cladding layer from inside to outside in sequence, and the yarn core can be a water-soluble yarn core.

[0007] By adopting the above technical scheme, under the premise of not changing the number of layers in the sandwich fabric, the yarn core in the base cloth layer is a water-soluble yarn core, which can play a temporary supporting or positioning role in the weaving process. After the fabric is completed, the water-soluble yarn core is removed through the water washing process to make the yarn hollow. Since the base cloth layer is provided with multiple layers, the yarns in the multiple layers are interwoven, the yarn core can be selected to be a water-soluble yarn core according to the requirement.

[0008] The above arrangement makes the fabric lighter in weight under the same tightness, and more fluffy and soft. The fluffy structure increases the air content between fibers, further reduces the thermal conductivity, and reduces the transfer of heat, so that the weight of the fabric can be reduced while maintaining good warmth retention.

[0009] Preferably, a napping layer is arranged on the skin.

[0010] By adopting the above technical scheme, the napping layer is arranged to further increase comfort and warmth retention.

[0011] Preferably, the base cloth layer closest to the skin among the plurality of base cloth layers is a skin-friendly layer, and the diameter of the yarn core gradually increases towards the skin-friendly layer.

[0012] By adopting the above technical solution, the diameter of the yarn core gradually increases towards the skin-friendly layer, the air layer formed after the water-soluble yarn core dissolves in the base cloth layer gradually increases, and can better absorb the sweat on the surface of the skin and conduct it to the outside to keep the skin dry, thereby increasing the warmth when close to the skin. The diameter of the yarn core in the base cloth layer away from the skin-friendly layer and close to the outside decreases, so that the air layer is small, thereby forming more air layers and increasing the windproof property when outside to reduce the transmission of heat and the possibility of heat exchange between the outside and the inside, thereby further improving the warmth of the fabric.

[0013] Since the diameter of the yarn core gradually increases towards the skin-friendly layer, the warmth is increased compared to the yarn core with a uniform diameter, and the weight is also reduced.

[0014] Preferably, the base cloth layer further comprises an inner cladding layer arranged between the yarn core and the outer cladding layer, and the inner cladding layer can be a water-soluble cladding layer.

[0015] By adopting the above technical solution, when the inner cladding layer is a water-soluble cladding layer, the yarn core can be selected to be a water-insoluble yarn core, which cooperates with the outer cladding layer. Compared to the hollow yarn made of the water-soluble yarn core, the range of the air layer formed is larger, and the bulkiness of the yarn is further increased, thereby further improving the warmth of the fabric. Compared to the weight of the fabric after washing the water-soluble yarn core, the weight of the fabric after washing the water-soluble cladding layer can be further reduced.

[0016] Preferably, the thickness of the inner cladding layer among the plurality of base cloth layers gradually increases towards the skin-friendly layer.

[0017] By adopting the above technical solution, when the inner cladding layer is a water-soluble cladding layer, the thickness of the inner cladding layer among the plurality of base cloth layers gradually increases towards the skin-friendly layer, the air layer formed after the water-soluble cladding layer dissolves gradually increases, thereby further increasing the warmth when close to the skin. The inner cladding layer away from the skin-friendly layer and close to the outside forms more air layers, thereby reducing the transmission of heat and further improving the warmth of the fabric.

[0018] Preferably, water-soluble filaments are arranged along the length direction of the yarn core or the outer cladding layer, and the water-soluble filaments are arranged at intervals around the axis of the yarn core.

[0019] By adopting the technical scheme, the water-dissolvable yarn is dissolved through the water washing process, the bulkiness in the outer covering layer or the yarn core is increased, the range of the air layer is further increased, and the warmth retention of the fabric is further improved.

[0020] Preferably, the water-dissolvable yarn is arranged in a spiral shape along the length direction of the yarn core.

[0021] By adopting the technical scheme, the water-dissolvable yarn is arranged in a spiral shape along the length direction of the yarn core, the content of the air layer in the outer covering layer or the yarn core is increased, and the warmth retention of the fabric is further improved.

[0022] Preferably, the cross section of the yarn core is arranged in a regular polygon shape.

[0023] By adopting the technical scheme, when the yarn core is made of the non-dissolvable thread and the inner covering layer is the water-dissolvable covering layer, the range of the air layer between the inner covering layer and the outer covering layer is increased after the water-dissolvable covering layer is dissolved, and the warmth retention is improved. In some specific conditions, the yarn core arranged in the base fabric layer of the outer layer can reflect light at multiple angles, and has a certain light reflection effect.

[0024] In summary, the utility model has the following beneficial effects:

[0025] 1. Without changing the number of layers in the sandwich fabric, the yarn core in the base fabric layer is water-dissolvable, which can temporarily support or position during weaving. After the fabric is completed, the water-dissolvable yarn core is dissolved to make the yarn hollow. The above arrangement makes the fabric lighter in weight under the same tightness, and more fluffy and soft, so that the warmth retention is maintained while the weight of the fabric is reduced.

[0026] 2. The air layer formed after the water-dissolvable yarn core in the base fabric layer is dissolved gradually increases towards the skin-friendly layer, so that the warmth retention when touching the skin is increased, the warmth retention of the fabric is further improved, and the weight is also reduced.

[0027] 3. When the cross section of the yarn core is arranged in a regular polygon shape, the yarn core arranged in the base fabric layer of the outer layer can reflect light at multiple angles in some specific conditions, and has a certain light reflection effect. BRIEF DESCRIPTION OF DRAWINGS

[0036] The following will be described in detail in combination with the accompanying Figure 1 - the accompanying Figure 7 , the present application is further described in detail.

[0037] Embodiments of the present application disclose a brocade and spandex sandwich cloth.

[0038] Embodiment 1:

[0039] A brocade and spandex sandwich cloth, referring to Figure 1 , Figure 2 , comprising a plurality of base cloth layers 1, in the present embodiment, the base cloth layers 1 are blended from nylon and spandex, having relatively excellent warmth retention and elasticity. Among them, the number of layers of the base cloth layers 1 is two or more, in the present embodiment, two base cloth layers 1 are specifically shown, it should be noted that the yarns in the adjacent two base cloth layers 1 are interwoven with each other.

[0040] For this purpose, in the present embodiment, the two base cloth layers 1 are respectively referred to as the first base cloth layer 11 and the second base cloth layer 12, wherein the first base cloth layer 11 is arranged close to the skin as a skin-friendly layer, and the yarns in the first base cloth layer 11 and the second base cloth layer 12 successively include a yarn core 13, an inner covering layer 14 and an outer covering layer 15 from inside to outside, wherein the yarn core 13 can be a water-soluble yarn core 13, and the inner covering layer 14 can be a water-soluble covering layer.

[0041] For the selection of the yarn core 13 in the multi-layer base cloth layer 1 and the inner covering layer 14, the yarn core 13 in the multi-layer base cloth layer 1 is all selected as the water-soluble yarn core 13, or the yarn core 13 and the inner covering layer 14 are both selected as the water-soluble covering layer. Or, the yarn core 13 of the yarn in the skin-friendly layer (the second base cloth layer 12) is the water-soluble yarn core 13, and the inner covering layer 14 of the yarn in the second base cloth layer 12 (the skin-friendly layer) is the water-soluble covering layer, which can be selected alternately when the base cloth layer 1 is three or more layers.

[0042] With reference to Figure 3 It should be noted that since the yarn generally includes warp 2 and weft 3, for the same layer of base cloth layer 1, the yarn core 13 of the water in several warp 2 (weft 3) can be selected as the water-soluble yarn core 13, or alternately selected, and the inner covering layer 14 of several weft 3 (warp 2) is selected as the water-soluble covering layer, or alternately selected, which is set according to the needs.

[0043] Further, the diameter of the yarn core 13 in the multi-layer base cloth layer 1 gradually increases towards the skin-friendly layer, as shown in Figure 4 That is, the diameter of the yarn core 13 in the first base cloth layer 11 is greater than the diameter of the yarn core 13 in the second base cloth layer 12. In order to improve the warmth of the fabric, the yarn core 13 in the first base cloth layer 11 can be a water-soluble yarn core 13, or the yarn core 13 in the multi-layer base cloth layer 1 can be a water-soluble yarn core 13, which is set according to the needs. Since the yarn core 13 in the first base cloth layer 11 is a water-soluble yarn core 13, the content of the air layer in the first base cloth layer 11 can be increased. Thus, the sweat on the surface of the skin can be better absorbed and conducted to the outside to keep the skin dry, thereby increasing the warmth when the skin is attached. The diameter of the yarn core 13 in the base cloth layer 1 away from the skin-friendly layer and close to the outside is reduced, so that the air layer is less, thereby forming more air layers and increasing the wind resistance outside to reduce the heat transfer and the possibility of heat exchange between the outside and the inside, thereby further improving the warmth of the fabric.

[0044] Or, the thickness of the inner covering layer 14 in the multi-layer base cloth layer 1 gradually increases towards the skin-friendly layer. For the thickness of the inner covering layer 14, the diameter of the yarn core 13 is reduced without changing the overall yarn diameter, and when the inner covering layer 14 in the first base cloth layer 11 is a water-soluble covering layer, the content of the air layer in the first base cloth layer 11 can be increased.

[0045] The implementation principle of the embodiment of the present application is that: under the premise of not changing the number of layers in the interlayer cloth, by selecting the yarn core 13 in the base cloth layer 1 as a water-soluble yarn core 13, or selecting the inner cladding layer 14 as a water-soluble cladding layer, the weight of the fabric is lighter under the same tightness after washing, and it is more fluffy and soft. The fluffy structure increases the air content between fibers, further reduces the thermal conductivity, reduces the transfer of heat, and reduces the weight of the fabric while maintaining good warmth.

[0046] Embodiment 2:

[0047] Referring to Figure 5 The difference from embodiment 1 is that a napping layer 4 is further arranged on the skin, and the napping layer 4 is arranged on the surface of the first base cloth layer 11 away from the second base cloth layer 12, so as to further improve the warmth retention performance and comfort of the fabric. The napping layer 4 can be realized by weaving, specifically as follows: first, weaving a front comb organization on one side of the base cloth layer 1, and the front comb organization is woven by short extension lines, then, the front comb organization is broken by a pulling process, so that the short extension lines form the nap of the napping layer. The length of the nap can be selected according to the warmth retention performance and comfort, which will not be described here.

[0048] Referring to Figure 6 Further, the cross section of the yarn core 13 is a regular polygon, and the specific number of sides is set according to the light to be reflected. In the embodiment, a regular pentagon is used for display, and correspondingly, the inner cladding layer 14 and the outer cladding layer 15 are also arranged as regular polygons corresponding to the yarn core 13. For the yarn core 13 arranged as a polygon, the base cloth layer 1 farthest from the skin-friendly layer can be selected to reflect light at multiple angles, having a certain light reflection effect.

[0049] Embodiment 3:

[0050] Referring to Figure 7 The difference from embodiment 1 is that the water-soluble silk 5 is arranged in the outer cladding layer 15 or in the yarn core 13 along the length direction thereof, and the water-soluble silk 5 is arranged at intervals along the axis of the yarn core 13. The water-soluble silk 5 is arranged in a spiral or wave shape along the length direction of the yarn core 13, which is specifically set according to the requirement.

[0051] When the yarn core 13 is provided with the water-soluble silk 5, the yarn core 13 itself is selected to be made of insoluble yarn, and the inner cladding layer 14 is selected to be a water-soluble cladding layer. At this time, the water-soluble silk 5 can also be arranged in the outer cladding layer 15, so as to further increase the content of the air layer.

[0052] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
