Description

Technical Field

[0001] This utility model relates to the field of fabrics, and more specifically, to a composite fleece fabric. Background Technology

[0002] As the name suggests, velvet refers to fabric with a napped surface. Velvet is widely used in our daily lives and is also used in sofa covers.

[0003] The plush texture on the fabric surface not only increases the feel of the sofa cover, but also improves its softness and warmth, ensuring a better user experience. Although the plush texture can increase the coefficient of friction of the fabric surface to some extent, it is not enough to guarantee the anti-slip performance of a sofa cover.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a composite fleece fabric.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a composite fleece fabric, comprising a surface layer and an inner layer, wherein the surface layer is knitted together with base yarn and warp yarn, and a plurality of protrusions formed by the warp yarn are formed on the side of the surface layer facing away from the inner layer. The warp yarn is formed by twisting a plurality of ply yarns, and the ply yarns have a plurality of protrusions on their surface. The warp yarns have gaps formed by the contact of the protrusions. A plurality of fleece is formed on the surface layer by a napping process. The inner layer is knitted from polyester yarn, and the knitting density of the inner layer is higher than that of the surface layer.

[0007] The present invention is further configured such that the protrusions located in the same column form a group of protrusions, the protrusions in two adjacent groups of protrusions are staggered, a groove is formed between any two adjacent protrusions, and the groove is surrounded by four protrusions.

[0008] The present invention is further configured such that: the ply yarn includes a core yarn and a slub yarn wrapped around the core yarn, the core yarn is made of low-elastic polyester yarn twisted together, and the slub yarn is made of cotton fiber twisted together.

[0009] The present invention is further configured such that the diameter of the warp yarn is greater than the diameter of the base yarn.

[0010] The present invention is further configured such that: the surface layer is woven from base yarn to form a weft plain knit structure, the warp yarn is sleeved on the weft plain knit structure and a plurality of front floats and back floats are formed on the surface layer, and the protrusion is composed of a plurality of front floats.

[0011] The present invention is further configured such that two adjacent front floating lines located on the same protrusion are separated by two row spacings.

[0012] In summary, this utility model has the following beneficial effects:

[0013] The protrusions on the surface increase the coefficient of friction, ensuring the fabric's anti-slip performance. The protrusions are formed by weaving warp yarns with numerous gaps, making it easier to pull out fibers during napping. This results in a higher number of fibers on the protrusion surface compared to other areas of the surface, further enhancing the coefficient of friction. Additionally, the ply yarns have raised dots, creating an uneven surface. Since the protrusions are woven from warp yarns, this further increases the coefficient of friction, thus improving the fabric's anti-slip performance. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Composite fleece, such as Figure 1 and Figure 3As shown, the fabric includes an outer layer 1 and an inner layer 2. The outer layer 1 is knitted from a base yarn 3 and warp yarns 4. On the side of the outer layer 1 facing away from the inner layer 2, several protrusions 9 formed by the warp yarns 4 are created. The warp yarns 4 are formed by twisting several strands 5, with several raised dots on their surfaces. Gaps formed by the contact of these raised dots are present within the warp yarns 4. The outer layer 1 has a napped surface. The inner layer 2 is knitted from polyester yarns, with a higher knitting density than the outer layer 1. The protrusions 9 protrude from the outer layer 1, increasing the coefficient of friction and ensuring the fabric's anti-slip properties. The protrusions 9 are formed by the warp yarns 4, and the warp yarns 4 have numerous gaps, making it easier for the fibers within the warp yarns 4 to move during the napping process. The protrusions are pulled out, resulting in a relatively larger number of fibers on the surface of protrusion 9 compared to other parts of the outer layer 1. This increases the coefficient of friction on the surface of protrusion 9. Furthermore, the protrusions on the surface of the ply yarn 5 make the surface of the warp yarn 4 uneven. Since protrusion 9 is woven from the warp yarn 4, the coefficient of friction on the surface of protrusion 9 is further increased. This design further improves the anti-slip performance of the fabric surface. The inner layer 2 is woven from polyester yarn, and its weave density is relatively high. Compared to knitted fabrics, woven fabrics have fewer gaps between yarns, making it difficult for dust to penetrate the inner layer 2 and contact the sofa, thus ensuring the fabric's dustproof effect. Additionally, polyester yarn has good abrasion resistance, ensuring the abrasion resistance of the inner layer 2.

[0020] like Figure 1 and Figure 2As shown, the protrusions 9 in the same column form a group of protrusions. The protrusions 9 in adjacent groups are staggered. A groove 6 is formed between any two adjacent protrusions 9. The groove 6 is surrounded by four protrusions 9. This arrangement results in a relatively large number of grooves 6 on the fabric surface, and the grooves 6 and protrusions 9 are evenly distributed on the surface layer 1, making the coefficient of friction on the surface layer 1 relatively consistent. The ply yarn 5 includes a core yarn 7 and a slub yarn 8 wrapped around the core yarn 7. The core yarn 7 is made of low-elastic polyester yarn twisted together, and the slub yarn 8 is made of cotton fiber twisted together. The low-elastic polyester yarn has the characteristics of low elasticity and high strength. On the one hand, it makes the deformation of the protrusion 9 structure less likely to be too large, ensuring the stability of the groove 6 structure. On the other hand, it can ensure the overall strength of the warp yarn 4, so that even if the warp yarn 4 is pulled, it will not be damaged. It also ensures a certain level of strength. The fluff formed by the cotton fibers is softer than that formed by the base yarn 3. Furthermore, cotton fibers have a certain degree of hygroscopicity, which can conduct some of the charge by absorbing moisture, reducing the possibility of static electricity generated on the surface layer 1. At the same time, the surface roughness of cotton fibers is higher than that of polyester fibers, ensuring the surface roughness of the protrusion 9. The base yarn 3 is made of twisted polyester fibers. Polyester fibers have high strength and long lifespan, ensuring the strength and lifespan of the surface layer 1. The polyester yarn is made of twisted hollow polyester filaments. Hollow polyester filaments can have a certain deformation in the diameter direction, thereby improving the elasticity of the inner layer 2 in the thickness direction, making the entire fabric feel softer. The hollow structure also helps to improve the overall warmth retention performance of the fabric.

[0021] like Figure 1 and Figure 2 As shown, the surface layer 1 is woven from the base yarn 3 to form a plain weave structure. The warp yarn 4 is wrapped around the plain weave structure and forms several front floats and back floats on the surface layer 1. The protrusion 9 is composed of several front floats. Specifically, the base structure of the surface layer 1 is a plain weave structure, and the back floats are located between two adjacent protrusions 9. The surface layer 1 is a knitted structure, which makes the surface layer 1 have more gaps. This arrangement facilitates the napping operation. The two adjacent front floats on the same protrusion 9 are separated by two row spacings. This arrangement makes the front floats on the protrusion 9 more compact and ensures the stability of the protrusion 9 structure.
