Textile finishing is a crucial stage in fabric production, involving a variety of techniques designed to enhance the appearance, texture, performance, and longevity of textiles. In Part 2 of our series, we explore five important textile finishing methods: fabric sizing, brushing, flocking fabric, wrinkle-resistant fabric, and flame-retardant treatment for fabric. Each of these processes serves a specific purpose and is applied based on the intended function and desired properties of the fabric. In this article, we will break down each process in detail, outlining its benefits, methods, precautions, and real-world applications.
Sizing
Fabric sizing is a traditional finishing method in the textile industry, mainly used for the surface treatment of yarns and fabrics to improve their processing performance and the quality of the final product.
Here is a detailed introduction to the textile sizing process:
Purpose of sizing
- Increase strength: Fabric Sizing can increase the strength of the yarn and reduce breakage during weaving.
- Reduce friction: The sizing layer can reduce the friction between yarns or fibers and improve their weavability.
- Protect fibers: The sizing layer can protect fibers from mechanical damage and wear.
- Improve wear resistance: Sizing can improve the wear resistance of the fabric and extend its service life.
- Improve handle: Sizing can improve the handle of the fabric, making it softer or stiffer depending on the desired style.
Sizing methods
- Immersion sizing: Immerse the yarn or fabric in a solution containing sizing agent, and the sizing agent adheres to the surface of the yarn.
- Foam sizing: Use foam to evenly coat the sizing agent on the yarn or fabric.
- Spray sizing: Spray the sizing agent on the yarn or fabric through a spray gun.
- Scraper sizing: Use a scraper to evenly coat the sizing agent on the yarn or fabric.
Sizing steps
- Pretreatment: Clean the yarn or fabric to remove grease, stains, and other impurities.
- Sizing preparation: Select the appropriate sizing agent and ratio according to the required performance.
- Sizing application: Pass the yarn or fabric through the sizing machine to evenly apply the sizing agent to the yarn or fabric.
- Drying: The sized yarn or fabric needs to be dried in a drying oven to fix the sizing agent.
- Post-treatment: The dried yarn or fabric may need to be post-treated, such as removing excess sizing agent and softening treatment.
Precautions for sizing
- Sizing agent selection: Select the appropriate sizing agent according to the material of the yarn and the required performance.
- Uniformity of sizing: Ensure that the sizing agent is evenly distributed on the yarn or fabric to avoid local thickening or thinning.
- Drying conditions: Control the drying temperature and time to ensure the proper curing of the sizing agent.
- Environmental protection and safety: Use environmentally friendly sizing agents and ensure that the sizing process is safe and harmless.
- Cost-effectiveness: Consider the cost-effectiveness of the sizing agent and the sizing process to meet the needs of the market and consumers.
Applications of sizing
Sizing finishing is widely used in various textiles, especially those yarns and fabrics that require additional strength and wear resistance during weaving or subsequent processing, such as:
- Warp yarns for weaving: Sizing can improve the strength and wear resistance of warp yarns and reduce breakage.
- Knitting yarns: Sizing can improve the weavability of knitting yarns and increase production efficiency.
- Non-woven fabrics: Sizing can improve the strength and wear resistance of non-woven fabrics.
Sizing is an important means to improve the processing performance and final product quality of textiles. By selecting the appropriate sizing agent and process, the processing performance of yarns and fabrics can be significantly improved. However, the sizing process needs to be precisely controlled to ensure the uniformity and quality of sizing.
Brushing
Brushed finishing is a fabric finishing method that enhances the surface characteristics of the fabric. By brushing, a layer of fine short fluff is created, giving the fabric a soft, warm, and full handle.
