Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile fabric technology, and in particular to a fleece fabric. Background Technology
[0002] Fleece fabric, as a classic warm fabric, is widely used in winter clothing, home textiles, and other fields due to its excellent warmth retention and soft feel. Traditional fleece is usually made of polyester fiber materials. After a series of complex processes such as brushing, combing, shearing, and fleecing, a fluffy pile structure is finally formed on the surface of the fabric. These piles can effectively lock in air, forming a warm air layer, thereby achieving a good warmth retention effect.
[0003] However, traditional fleece has certain limitations in terms of functionality and appearance design. Firstly, there are limitations to improving the warmth retention of fleece fabric. The thickness and density of the fleece surface determine its warmth retention performance. If it is too thick, it will affect breathability and wearing comfort; if it is too thin, it cannot effectively lock in air and slow down heat loss, resulting in insufficient warmth retention. Secondly, most fleece products on the market currently have a plain weave, which, while providing some warmth, fails to meet the diverse aesthetic needs of consumers. Utility Model Content

[0007] Preferably, the fleece fabric is formed by an upper needle plate with two needle tracks and a lower needle cylinder with two needle tracks, using an eight-way, one-cycle knitting method, wherein:
[0008] For rows 1 and 5, the first stitch of the upper needle plate is looped and the second stitch is floated, while the first stitch of the lower needle cylinder is floated and the second stitch is looped.

[0011] The first and second needles of the upper needle plate in rows 4 and 8 are floating threads, and the first and second needles of the lower needle tube are looped.
[0012] The first and second needles of the upper needle plate in the 7th row are floating threads, and the first and second needles of the lower needle cylinder are gathered.
[0013] Preferably, the upper needle plate and the lower needle cylinder are arranged in a ribbed needle configuration, with the upper needle plate using an AB needle arrangement and the lower needle cylinder using a BA needle arrangement.

[0020] By adopting the above technical solution, the beneficial effects of this utility model are as follows:
[0021] 1. The fleece fabric of this utility model forms an air gap in the fabric by connecting the outer layer and the inner layer through the middle layer. The air gap can block the heat exchange between the inside and outside of the fabric, making it difficult for the body's heat to be lost. At the same time, it blocks the entry of cold air from the outside, which significantly improves the warmth performance while helping to reduce the weight of the fabric and improve the comfort of wearing it.
[0022] 2. The surface layer of this utility model has raised, wavy protrusions, which on the one hand can make the fabric surface present a three-dimensional and layered feel, and on the other hand can increase the surface area of the fabric through the unique protrusion effect of the surface layer, thereby storing more air, insulating the cold air outside, slowing down heat loss, and further improving the warmth retention performance of the fabric.
