Hey there! As a supplier of SMS non woven fabric products, I often get asked about the quality guarantee for these materials. So, I thought I'd take a few minutes to break it down for you and give you the lowdown on what makes our SMS non woven fabrics top - notch.
First off, let's talk about what SMS non woven fabric is. SMS stands for Spunbond - Meltblown - Spunbond. It's a composite non woven fabric that combines the strength and durability of spunbond layers with the filtration and barrier properties of the meltblown layer. This unique combination makes it suitable for a wide range of applications, from medical and hygiene products to agricultural and industrial uses.
Raw Material Selection
The quality of SMS non woven fabric starts with the raw materials. We're super picky about the polymers we use. We source high - quality polypropylene resin, which is the main ingredient in our fabrics. This resin has consistent properties, like melt flow rate and molecular weight, which are crucial for ensuring the uniformity and performance of the final product.
We work closely with our suppliers to make sure that the raw materials meet our strict standards. We conduct regular inspections and tests on incoming materials. For example, we check the melt flow index of the polypropylene resin. If it's outside the acceptable range, we won't use it. This way, we can be confident that we're starting with the best possible materials to create our SMS non woven fabrics.
Manufacturing Process
The manufacturing process of SMS non woven fabric is a key factor in its quality. We use state - of - the - art equipment and advanced technology to produce our fabrics. The spunbond and meltblown processes are carefully controlled to ensure the proper formation of fibers and the bonding between layers.
During the spunbond process, the polypropylene resin is melted and extruded through spinnerets to form continuous filaments. These filaments are then laid down on a moving belt to form a web. The web is then bonded together using heat or chemicals. In the meltblown process, the molten polymer is blown by high - speed air to form fine fibers, which are then deposited on the spunbond web.
We monitor every step of the manufacturing process. We have sensors and control systems in place to regulate factors like temperature, pressure, and speed. For instance, the temperature during the extrusion process needs to be just right. If it's too high, the fibers might break or become too thin. If it's too low, the fibers won't be fully formed. By keeping a close eye on these parameters, we can produce SMS non woven fabrics with consistent quality.
Quality Control Testing
We don't just rely on the manufacturing process to ensure quality. We also have a comprehensive quality control testing program. We test our SMS non woven fabrics at multiple stages of production.
First, we do in - process testing. While the fabric is being made, we take samples at regular intervals and test them for things like basis weight, thickness, and strength. Basis weight is the weight of the fabric per unit area, and it's an important indicator of its quality. If the basis weight is too high or too low, it can affect the fabric's performance.
After the fabric is produced, we conduct more extensive testing. We test for properties like tensile strength, tear strength, filtration efficiency, and barrier performance. For example, in the medical field, the filtration efficiency of SMS non woven fabric is crucial. We use specialized equipment to measure how well the fabric can filter out particles of different sizes.
We also perform aging tests to simulate the effects of long - term use. We expose the fabric to different environmental conditions, like heat, humidity, and UV light, and then test its properties again. This helps us ensure that our SMS non woven fabrics will maintain their performance over time.
Product Certification
To give our customers even more peace of mind, our SMS non woven fabric products are certified to meet various international standards. We have certifications like ISO 9001 for quality management systems, which means we have a well - documented and efficient quality control process in place.
In addition, depending on the application of the fabric, we may have other relevant certifications. For medical and hygiene products, our fabrics meet standards like EN 13795 for hospital gowns and drapes. For agricultural products, they may meet certain environmental and performance standards. These certifications are a testament to the quality and reliability of our SMS non woven fabric products.
Applications and Quality Assurance
Our SMS non woven fabric products are used in a wide range of applications, and we provide tailored quality assurance for each one.
Medical and Hygiene Products
In the medical and hygiene field, the quality of SMS non woven fabric is of utmost importance. Our fabrics are used in products like surgical gowns, masks, and disposable diapers. For surgical gowns, we ensure that the fabric has excellent barrier properties to prevent the transmission of pathogens. We test the fabric's resistance to blood and other fluids to make sure it meets the strict requirements of the medical industry.
