Abstract
Description
Technical Field
[0001] This utility model relates to the textile field, and more specifically, to a warm knitted fabric. Background Technology
[0002] Knitted greige fabric refers to fabric woven through knitting processes without dyeing or finishing treatment. It is an intermediate product in the process from fiber to clothing or other textile products. Through different knitting techniques, different materials, and different layer-by-layer composites, knitted greige fabric can exhibit different properties.
[0003] For knitted fabrics that require a certain level of warmth, a thicker knitting structure is often used to reduce heat exchange caused by air circulation and ensure the warmth of the knitted fabric. However, such a thick knitting structure can lead to a stiffer fabric texture and reduced comfort. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a warm knitted fabric.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a warm knitted fabric, comprising an outer layer and an inner layer, wherein the inner layer is provided with a plurality of pile on the side near the outer layer, and the outer layer is provided with a plurality of raised ridges arranged in a linear array on the side near the inner layer, wherein the distance between adjacent raised ridges is greater than or equal to the width of the raised ridges, and the inner layer and the outer layer are sewn together by a sewing thread, wherein the sewing thread passes through the raised ridges.
[0006] The present invention is further configured such that: the inner layer includes a first yarn and a second yarn, the first yarn forming a pile, and the first yarn using stiff fibers.
[0007] The present invention is further configured such that the second yarn has a hollow structure.
[0008] The present invention is further configured such that the diameter of the second yarn is greater than the diameter of the first yarn.
[0009] The present invention is further configured such that: the outer layer is woven from thermal insulation yarn into a semi-weave structure.
[0010] The present invention is further configured such that the heat-insulating yarn is made of twisted cotton fiber bundles.
[0011] In summary, this utility model has the following beneficial effects: the raised ridges separate the outer and inner layers, and combined with the stiffness of the first yarn, ensure that the pile between adjacent raised ridges can remain upright, slow down the air flow between the outer and inner layers, form an air layer, and thus reduce heat exchange. Warmth is achieved through the pile and air layer, ensuring that the knitted fabric is fluffy and soft. The first yarn is made of twisted polyester fiber filaments, which have good stiffness. The second yarn is made of twisted hollow irregular polyester fiber filaments, and the larger diameter of the second yarn improves the warmth retention of the inner layer. Attached Figure Description

[0013] Figure 2 This is a diagram of the tissue structure of the outer layer in this utility model.
[0014] In the diagram: 1. First yarn; 2. Second yarn; 3. Warm yarn. Detailed Implementation
[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0016] Example: A warm knitted fabric, such as Figure 1 , Figure 2 As shown, it includes an outer layer and an inner layer. The inner layer has several piles on the side near the outer layer, and the outer layer has several raised ridges arranged in a linear array on the side near the inner layer. The distance between adjacent raised ridges is greater than or equal to the width of the raised ridges. The inner layer and the outer layer are sewn together by a stitch that passes through the raised ridges. The inner layer includes a first yarn 1 and a second yarn 2. The first yarn 1 forms the pile and is made of stiff fiber. The second yarn 2 has a hollow structure and its diameter is greater than that of the first yarn 1.
[0017] Specifically, the outer layer is woven into a single-sided terry fabric using a circular knitting machine with first yarn 1 and second yarn 2. First yarn 1 is made of twisted polyester fibers, which have good stiffness. First yarn 1 forms several loops floating on one side of the outer layer. These loops are macroscopically represented as several piles. The raised ridges separate the outer and inner layers. Combined with the stiffness of first yarn 1, this ensures that the piles between adjacent raised ridges remain upright, slowing down the airflow between the outer and inner layers and forming an air layer. This reduces heat exchange and provides warmth through the piles and air layer, ensuring that the knitted fabric is fluffy and soft. The distance between the raised ridges ensures the area of the air layer and the warmth of the knitted fabric. The seams are concentrated at the raised ridges to ensure the thickness of the air layer. Second yarn 2 is made of twisted hollow, irregularly shaped polyester fibers. Combined with the larger diameter of second yarn 2, this improves the warmth of the inner layer.
[0018] like Figure 1 , Figure 2 As shown, the outer layer is woven into a semi-weave structure by the thermal insulation yarn 3. The thermal insulation yarn 3 is made by twisting cotton fiber bundles. Specifically, the thermal insulation yarn 3 is made by twisting three cotton fiber bundles. The cotton fiber bundles have good thermal insulation properties, which improves the thermal insulation of the outer layer. At the same time, the outer layer forms a raised rib structure through the semi-weave structure. The raised rib structure woven in one piece has good structural stability.
[0019] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
