• The Importance of Dimensional Stability in Uniform Fabric Orders May 15, 2024
    Workwear and uniforms serve a vital role in various industries, ranging from hospitality to manufacturing, where durability and functionality are paramount. However, one often overlooked yet crucial aspect of these garments is dimensional stability in the fabric used. Dimensional stability refers to the ability of fabric to maintain its original shape and size despite repeated laundering and wear. Imagine a workforce clad in ill-fitting uniforms that have shrunk or stretched after a few washes. Such garments not only compromise the professional image of the organization but also affect the morale and confidence of the employees. Dimensionally stable fabrics maintain the integrity of the uniform's design, ensuring a consistent and polished appearance over time. Fabrics with excellent dimensional stability can prolong the lifespan of garments. Fabrics that resist shrinking or stretching maintain their shape and size, reducing the need for frequent replacements. To conclude, dimensional stability plays a vital role in ensuring professional appearance of workwear uniforms.   What factors influence shrinkage?   1.     Different raw materials in fabrics lead to different shrinkage rates. Generally, fibers with high moisture absorption will swell in water, increasing in diameter and shortening in length, resulting in higher shrinkage. For example, some viscose fibers have a water absorption rate of up to 13%, whereas synthetic fiber fabrics have poor moisture absorption and therefore have lower shrinkage rates. 2.     The density of the fabric also affects shrinkage. If the warp and weft densities are similar, the shrinkage rates in the warp and weft directions will also be similar. Fabrics with a higher warp density will shrink more in the warp direction, whereas fabrics with a higher weft density than warp density will shrink more in the weft direction. 3.     The thickness of the yarn in the fabric affects the shrinkage rate. Fabrics made with thicker yarns will have higher shrinkage rates, while those made with finer yarns will have lower shrinkage rates. 4.     Different production processes result in different shrinkage rates. Generally, during the weaving and dyeing processes, fibers undergo multiple stretches. Fabrics that are processed for longer durations and subjected to greater tension will have higher shrinkage rates, and vice versa.   Returning to our products, overall, the shrinkage rates of the workwear and uniform fabrics we produce are quite satisfactory. For instance, the shrinkage rate of our polyester wool blended fabrics and polyester cotton fabrics is typically controlled within ±2%. For nylon cotton blend fabrics, the shrinkage rate is controlled within ±3%, and for pure cotton fabrics, it is controlled within ±3.5%. Our technicians have thoroughly considered every aspect, including fabric composition, yarn configuration, and production processes, to achieve the best possible shrinkage performance.    
  • The Importance of Color Fastness in Fabric Specifications Mar 18, 2024
    In fabric specifications, there are numerous critical indicators such as yarn density, tensile strength, tear strength, shrinkage rate, and color fastness, each directly impacting the quality and performance of the fabric. However, among these indicators, color fastness stands out as particularly crucial, directly influencing the fabric's lifespan and visual appeal.   Color fastness refers to a fabric's ability to maintain color stability under different conditions, serving as a significant criterion for measuring fabric durability and quality. Good color fastness implies that the fabric can retain stable colors during washing, exposure to sunlight, friction, perspiration, etc., thus prolonging its lifespan and preserving its aesthetic appeal. There are four types of color fastness commonly required for accessing fabric’s color stability which are color fastness to washing, to light, to crocking, and to perspiration. Color fastness to washing assesses the fabric's ability to maintain color stability during the washing process, while color fastness to light evaluates its resistance to color fading when exposed to sunlight or artificial light sources. Color fastness to crocking measures the fabric's resistance to color fading or staining when subjected to friction with other surfaces. Color fastness to perspiration evaluates how the fabric maintains its color stability when in contact with sweat, reflecting its durability and appearance during wear.   As a professional workwear and uniform supplier, Bscam has implemented stringent color fastness standards for our polyester wool blend fabric, polyester cotton blend fabric, and nylon cotton blend camouflage fabric to ensure product quality and performance. Our factories utilize advanced testing methods and equipment to conduct thorough inspections on each batch of fabric, ensuring that their color fastness meets relevant standards and requirements. Below is the color fastness test report for shipment of our NylonCotton camouflage fabric. For the test results of shipments for our PolyWool and PolyCotton Fabric, you can check in About Us/Inspection for details. Overall, they demonstrate excellent performance in the SGS lab. tests of color fastness to crocking, to light, to washing and to perspiration, with ratings reaching 4-4.5 grade.     Color fastness plays a crucial role in fabric specifications, ensuring product quality and performance. Bscam will continue to focus on improving color fastness to meet customer demands and provide high-quality uniform and workwear fabrics.
