Different fashion fabrics may have different organizational structures. Generally, what we call fabric organization mainly refers to the rules of yarn interweaving. For woven fabrics, it refers to the interweaving pattern of warp and weft yarns, such as plain weave, twill weave, satin weave, and jacquard. For knitted fashion fabrics, they mainly include plain weave, ribbed weave, single-sided and warp satin, etc. Generally, it is not necessary to analyze the interweaving patterns of yarns when inspecting fabrics.
You only need to check whether the appearance and size of the pattern in the fashion fabric meet the usage requirements. During inspection, you can visually observe or use a magnifying glass or cloth mirror to observe the yarn interweaving patterns and pattern appearance of the fabric. Any errors in structure or pattern will be deemed as major defects and are considered to be unqualified products. The second step is to detect the yarn count. In fact, the yarn count indicates the thickness of the yarn, which cannot be judged by visual inspection. Generally, special testing equipment is required for inspection.
Next, check the density of the fashionable fabric. For now, for woven fabrics, the number of yarns per unit length in the warp or weft direction can be divided into warp density and weft density. Several inspection methods can be used: 1. Decomposition and yarn splitting method; 2. Fabric mirror analysis method; 3. Oblique grating density analysis method.
Then the weight of the fashion fabric needs to be checked. During the inspection process, the specifications of knitted fabrics are usually expressed in terms of unit area weight, such as grams/square meter, commonly known as gram weight. You can use a standard sampler to take samples and weigh them with an electronic balance, or you can weigh the entire piece and then calculate the actual weight of the fabric according to the relevant formula.
During the inspection process, if you already know the weight of each yard of fashion fabrics in different ranges, you can get the square meter weight by looking up the table. When conducting weight inspection of fashion fabrics, compare the actual weight with the required weight. Normally, it is required to control the fabric weight error within the range of -2% to +5%.
