Description

Technical Field

[0001] This utility model relates to a suede fabric, specifically a weft-knitted thin suede fabric. Background Technology

[0002] Suede fabric refers to a simulated fabric that mimics animal suede. Its main characteristic is a dense, fine, and soft short pile on the fabric surface. The fabric is soft and possesses good warmth retention, moisture absorption, and abrasion resistance. Suede fabrics are mainly made from raw materials such as polyester microfiber. Based on the direction of the napping material on the fabric surface, they are divided into two categories: warp-pile suede (warp-pile suede) and weft-pile suede (weft-pile suede).

[0003] Knitted suede fabrics are further divided into warp-knitted suede and weft-knitted suede. With the development of weft knitting technology and the continuous emergence of various new raw materials, the development and innovation of weft-knitted products are also changing rapidly. When suede fabric is used to make home textile products such as curtains, sofa covers, and decorative fabrics, the fabric should not be too thick and usually needs to have patterns to enhance its aesthetic appeal. Therefore, this application provides a weft-knitted thin suede fabric. Utility Model Content

[0004] The purpose of this invention is to provide a weft-knitted thin suede fabric, which aims to have a textured jacquard effect with partial napping, thereby enhancing the aesthetics of the suede fabric and enriching the product structure.

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: a weft-knitted thin suede fabric, comprising: a base fabric layer and a checkered suede layer; the checkered suede layer includes a first region, a second region, a third region and a fourth region, wherein the first region and the third region are loops weft-knitted from island yarn and 4.4tex / 24f high-shrinkage polyester yarn, and the second region and the fourth region are loops weft-knitted from 6.7tex / 48f high-shrinkage polyester yarn.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the specifications of the island yarn are 11.7 tex / 36f.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the base fabric layer is weft-knitted from diatomaceous earth modified viscose fiber yarn.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the base fabric layer and the checkered suede layer are connected by quilting.

[0009] The beneficial effects of this utility model are as follows: Based on the weft-knitted thin suede fabric of this utility model, the front of the checkered suede layer has a significant concave-convex effect, while the reverse side is flat. The raised square areas are divided by concave lines, which not only achieves a lively checkered appearance of the fabric, but also avoids damage to the high-shrinkage polyester yarn loops during the napping process; the base fabric layer can effectively absorb harmful chemicals, eliminate odors, and has an inhibitory effect on Candida albicans, Escherichia coli and Staphylococcus aureus, and the formaldehyde removal rate is greater than 85%.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] Combination Figure 1-3 This embodiment will be described in detail. A weft-knitted thin suede fabric includes: a base fabric layer 1 and a checkered suede layer 2; the checkered suede layer 2 includes a first region 3, a second region 4, a third region 5 and a fourth region 6, wherein the first region 3 and the third region 5 are loops weft-knitted from island yarn and 4.4tex / 24f high-shrinkage polyester yarn, and the second region 4 and the fourth region 6 are loops weft-knitted from 6.7tex / 48f high-shrinkage polyester yarn.

[0016] Furthermore, the island-island yarn has a specification of 11.7 tex / 36f.

[0017] Specifically, the checkered suede layer 2 is woven by a double-sided circular knitting machine. The specific yarn feeding method is as follows: the total number of yarn feed paths is 60F. Odd-numbered paths from 1 to 48F simultaneously feed 11.7tex / 36f island-island yarn (37 islands) and 4.4tex / 24f high-shrinkage polyester yarn, while even-numbered paths feed 6.7tex / 48f high-shrinkage polyester yarn. Odd-numbered paths from 49 to 60F feed 6.7tex / 48f high-shrinkage polyester yarn, while even-numbered paths simultaneously feed 11.7tex / 36f island-island yarn (37 islands) and 4.4tex / 24f high-shrinkage polyester yarn. This is repeated every 4F, arranged in a triangular pattern. Figure 3As shown, "Λ" represents a looped triangle, and "-" represents a floating triangle; the transverse density of the checkered suede layer 2 is 84.6 rows / 5cm, the longitudinal density is 110.2 columns / 5cm, the blank weight is 250g / ㎡, the blank width is 150cm, the loop length of the 1st and 3rd layers is 305mm / 100 stitches, and the loop length of the 2nd and 4th layers is 185mm / 100 stitches; after pre-shrinking and opening the fibers of the checkered suede layer 2, its front side exhibits a raised square effect, in which the first region 3 and the third Region 5 consists of loops made of island yarn and high-shrinkage polyester yarn, protruding from the fabric surface to facilitate subsequent napping processes; the narrow strip-shaped second region 4 and fourth region 6 consist of loops made of high-shrinkage polyester yarn, recessed into the fabric surface, dividing the protruding square area with recessed lines, which not only achieves a lively square appearance of the fabric, but also avoids damage to the high-shrinkage polyester yarn loops during napping; this grid suede layer 2 has a distinct concave-convex effect on the front, while the reverse side is flat, and the reverse side is composite with the base fabric layer 1.

[0018] Furthermore, the base fabric layer 1 is weft-knitted from diatomaceous earth-modified viscose fiber yarn. Diatomaceous earth is a sedimentary deposit of diatom remains, a siliceous precipitate rock formed by biological transformation, with diatoms as its main component. It is an organic opal mineral component, and because it differs from opals of ordinary origin, it is called diatomaceous opal. As a natural mineral material, diatomaceous earth contains no harmful chemicals and not only has advantages such as low density, water resistance, and non-flammability, but also has deodorizing, moisture-absorbing, and indoor harmful gas-absorbing functions. By blending nano-sized diatomaceous earth with viscose spinning solution and using wet spinning, modified viscose fibers that can remove harmful gases are obtained. Fabrics woven from these yarns can effectively absorb harmful chemicals, eliminate odors, inhibit Candida albicans, Escherichia coli, and Staphylococcus aureus, and have a formaldehyde removal rate of over 85%.

[0019] Furthermore, the base fabric layer 1 and the checkered suede layer 2 are connected by quilting. The checkered suede layer 2 has a distinct uneven effect on the front, while the reverse side is flat. The reverse side of the checkered suede layer 2 is bonded to the base fabric layer 1, and the two layers of fabric are laminated together by quilting. Compared with suede fabric formed by multiple layers, the suede fabric provided in this embodiment is thinner.

[0020] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
