Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a long velvet double-layer composite warm-keeping non-woven fabric. Background Art

[0002] Non-woven fabrics have no warp or weft, so they are very convenient to cut and sew, and they are light and easy to shape.

[0003] At present, because non-woven fabric is a kind of fabric that does not require spinning and weaving, it is just that textile short fibers or filaments are oriented or randomly arranged to form a fiber mesh structure, and then reinforced by mechanical, thermal bonding or chemical methods. Therefore, the strength of the non-woven fabric in the extension direction is less than the strength of the non-woven fabric in the truncation direction. Utility Model Content

[0004] The purpose of the utility model is to improve the strength of the nonwoven fabric in the extension direction.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a long velvet double-layer composite thermal non-woven fabric including a non-woven fabric layer and a velvet layer. The non-woven fabric layer is mixed with low-melting-point fibers. The velvet layer includes velvet clusters and a plurality of spaced-apart and parallelly arranged velvet threads. The velvet threads are threaded and connected to a plurality of velvet clusters. The velvet clusters and / or velvet threads are adhered to the non-woven fabric layer through the low-melting-point fibers.

[0006] Furthermore, the suede layer is made of EW suede material.

[0007] Furthermore, the interval between two adjacent wool threads is 1 mm to 5 mm.

[0008] Furthermore, the interval between two adjacent piles on the same pile thread is 2 cm to 6 cm.

[0009] Furthermore, the diameter of the wool yarn is 20D to 100D.

[0010] Furthermore, the suede layer has a grammage of 20 g / m 2 ~200g / m 2 .

[0011] Furthermore, the mass ratio of the low melting point fiber to the non-woven fabric layer is 1 to 3:10.

[0012] Furthermore, the weight of the nonwoven fabric layer is 10 g / m 2 ~200g / m 2 .

[0013] Furthermore, the fiber fineness of the non-woven fabric layer is 0.8D to 15D.

[0014] Furthermore, the melting point of the low-melting-point fiber is 80°C to 170°C.

[0015] Compared with the prior art, the beneficial effects of the long filament velvet double-layer composite heat-preserving non-woven fabric in the embodiment of the present utility model are as follows: low-melting-point fibers are mixed in the non-woven fabric layer, and the velvet surface layer laid on the surface of the non-woven fabric layer includes velvet tufts and velvet threads connecting a plurality of velvet tufts. After the low-melting-point fibers are melted, they adhere to the velvet tufts and velvet threads of the non-woven fabric layer and the velvet surface layer, which helps to improve the tensile strength of the non-woven fabric layer in the length direction of the velvet threads, thereby improving the overall strength of the long filament velvet double-layer composite heat-preserving non-woven fabric. Moreover, the velvet tufts connected by the velvet threads improve the touch feeling of the surface of the long filament velvet double-layer composite heat-preserving non-woven fabric, and enhance the skin-friendly property, drapability and heat-preserving property. The traditional down feathers are individual velvet tufts, which are prone to the problem of cotton running and agglomeration after washing, resulting in a decrease in heat preservation performance. However, in this solution, the velvet threads of the velvet surface layer play a fixing effect on the velvet tufts and the non-woven fabric layer, which helps to improve the effect after washing and further improves the heat preservation performance of the fabric after washing. At the same time, the non-woven fabric contains fine-denier fibers, which further enhances the heat preservation effect. Description of the Drawings

[0020] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0021] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "vertical", "horizontal", "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. in the present utility model is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0022] In the description of the utility model, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "provided with", "connection", etc. shall be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0023] As Figures 1 to 3 shown, a long filament velvet double-layer composite heat-preserving non-woven fabric of a preferred embodiment of the present utility model includes a non-woven fabric layer 1 and a velvet surface layer 2. The non-woven fabric layer 1 is mixed with low-melting-point fibers. The velvet surface layer 2 includes velvet tufts 4 and a plurality of spaced and parallel velvet threads 3. The velvet threads 3 penetrate and connect a plurality of velvet tufts 4, and the velvet tufts 4 and / or the velvet threads 3 are adhered to the non-woven fabric layer 1 through low-melting-point fibers.

[0024] Based on the above scheme, the velvet thread 3 is fixed in the extending direction of the non-woven fabric layer 1, which helps to improve the tensile strength of the non-woven fabric layer 1 in the extending direction, and further improves the overall strength of the non-woven fabric layer 1.

[0025] Preferably, the velvet surface layer 2 is made of EW velvet material. The velvet surface layer 2 is bionic goose down, including velvet threads 3 and velvet tufts. A plurality of velvet tufts are arranged at intervals and are strung together by the velvet threads 3. The velvet surface layer 2 realizes both the natural characteristics of down, such as fluffy heat preservation, soft and smooth silkiness, and can overcome the disadvantages of natural down, such as easy feather leakage, easy accumulation, easy dust generation, possible allergy or peculiar smell. Although the velvet surface layer 2 is an existing material, however, since the structure of the velvet surface layer 2 is a single-line form material with the velvet thread 3 as the skeleton, it is difficult to use in the traditional tailoring process mainly based on flat fabrics, and it is also difficult to transport. After the velvet surface layer 2 is made into the long filament velvet double-layer composite heat-preserving non-woven fabric of this embodiment, the single-line form material is processed into a sheet-shaped composite material, which is convenient for subsequent transportation, processing and use.

[0026] EW velvet provides characteristics such as heat preservation, softness, and skin-friendliness similar to the combination of down and silk. Compared with the single non-woven fabric layer 1, this embodiment can significantly improve the skin-friendliness, drapability and heat preservation of the composite non-woven fabric. And compared with melting the velvet surface layer 2 in the double non-woven fabric layer 1, the long filament velvet double-layer composite heat-preserving non-woven fabric of this scheme has better drapability, is softer and more skin-friendly. It is precisely because one side of the velvet surface layer 2 is close to the skin, so the wearing experience is improved, and because it is not a double non-woven fabric layer 1 composite structure, its cost is lower.

[0027] Compared with natural goose down, the velvet surface layer 2 overcomes the problem that traditional down fiber materials are easy to shift and agglomerate after washing due to the fixation of the velvet tufts 4 by the velvet threads 3. This embodiment has good washability.

[0028] Preferably, the distance between two adjacent wool yarns 3 is set to be 1 mm to 5 mm; the distance between two adjacent wool tufts 4 on the same wool yarn 3 is 2 cm to 6 cm. Specifically, in this embodiment, the distance between two adjacent wool yarns 3 is set to be 2.12 mm, and the closely arranged wool yarns 3 further improve the mechanical properties of the non-woven fabric layer 1 in the extending direction.

[0029] Preferably, the diameter of the wool yarn 3 is 20 D to 100 D. Specifically, in this embodiment, the wool yarn 3 with 70 D is selected to further improve the mechanical properties of the non-woven fabric layer 1 in the extending direction.

[0030] Preferably, the non-woven fabric layer 1 and the wool fabric layer 2 are made of PET material. The PET non-woven fabric layer 1 is favored for its durability, cost-effectiveness and environmental friendliness. It is easy to recycle, reducing the impact on the environment. At the same time, the PET non-woven fabric layer 1 has high strength and stability, suitable for various industrial applications. The wool fabric layer 2 made of PET material provides lightweight and warm characteristics, while maintaining the advantages of easy cleaning and wrinkle resistance. The composite use of this material not only improves the functionality of the product, but also enhances its market competitiveness.

[0031] Preferably, the non-woven fabric layer 1 and the wool fabric layer 2 are made of PET material, wherein the PET material is recycled fiber. Specifically, in this embodiment, the proportion of recycled fiber in the wool fabric layer 2 reaches up to 100%, and the proportion of recycled fiber selected for the non-woven fabric layer 1 reaches 80% to 95%. The use of recycled PET fibers helps to reduce the environmental burden, reduce the dependence on virgin petroleum resources, and reduce the generation of plastic waste; the use of recycled fibers reflects the concept of sustainable development, promotes the circular economy, and provides a practical solution for reducing resource waste and environmental pollution; recycled PET is usually of lower cost, reducing the production cost and making this embodiment more competitive in the market.

[0032] Preferably, the grammage of the wool fabric layer 2 is 20 g / m 2 ~200 g / m 2 . This makes the wool fabric layer 2 have a variety of selectivities.

[0033] Preferably, the mass ratio of the low-melting-point fiber to the non-woven fabric layer 1 is 1 to 3:10. Ensure that it adheres to the wool fabric layer 2 after melting at high temperature and then is wound into a roll.

[0034] Preferably, the non-woven fabric layer 1 is flat cotton. Flat cotton, also known as hot air non-woven fabric, hot air bonded non-woven fabric, belongs to one of the hot air bonded (hot rolling, hot air) non-woven fabrics. Hot air non-woven fabric is formed by using hot air on the drying equipment to penetrate the fiber web after fiber carding, so that it is heated and bonded to form the non-woven fabric layer 1. The evenly distributed fibers in the non-woven fabric layer 1 provide a soft and flat surface. Secondly, flat cotton has good elasticity and breathability. In addition, the hot air bonding technology does not require chemical adhesives, reducing the impact on the environment and meeting the requirements of modern environmental protection production. The hot air non-woven fabric has strong adhesion, improving the durability and stability of the material. Since flat cotton needs to maintain fluffiness, it usually sacrifices structural strength. In this embodiment, compared with a single flat cotton, the structural strength is improved through the yarn 3, while meeting the two requirements of heat preservation and strength.

[0035] Preferably, the grammage of the non-woven fabric layer 1 is 10 g / m 2 ~200 g / m 2 . The wide range of grammage allows the selection of non-woven fabric layers 1 with different thicknesses according to specific application requirements, so as to adapt to various uses from light to heavy.

[0036] Preferably, the fineness of the fibers of the non-woven fabric layer 1 is 0.8 D to 15 D. Different grammages and fiber finenesses enable the non-woven fabric layer 1 to be used in different fields, such as medical and health, agricultural covering, home decoration, etc.

[0037] Preferably, the melting point of the low-melting-point fiber is 80°C to 170°C. Based on this, the heating temperature during processing is selected as 110°C to 250°C, and the melting point of other fibers in the non-woven fabric layer 1 is 220°C to 270°C.

[0038] Specifically, the production steps are as follows: The coiled material of the velvet layer 2 with a certain width is introduced into the flat cotton production line by the way of reverse winding, so that the velvet layer 2 covers the flat cotton that has been carded and laid. Subsequently, the velvet layer 2 and the flat cotton are conveyed to the oven together by the conveyor mesh belt. The flat cotton contains 10% to 30% of low-melting-point fibers, which melt in the oven and bond with the velvet layer 2 to form the composite material of this embodiment, and finally it is collected into a roll.

[0039] In summary, the embodiment of the present utility model provides a long filament velvet double-layer composite heat-preserving non-woven fabric, in which the yarn 3 is fixed in the extending direction of the non-woven fabric layer 1, which helps to improve the tensile strength of the non-woven fabric layer 1 in the extending direction, and thus improves the overall strength of the non-woven fabric layer 1.

[0040] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present utility model.
