Function Outdoor Waterproof Fabrics Manufacturers

In the production process of Function Outdoor Waterproof Fabrics, what tests are mainly used in the quality inspection link to ensure that the waterproof performance meets the standards?

The source of fabric production lies in the raw materials, and the quality of the raw materials directly determines the waterproof performance of Function Outdoor Waterproof Fabrics. Colorful Fish Textile is located in Huangmei County, Hubei Province. With many high-end water jets, air jet looms, double twisting machines, advanced warping, sizing, tentering machines and large-scale water treatment equipment introduced from Japan, South Korea, Germany and other places, it has created a production base with an annual output of nearly 60 million meters of high-end fabrics. In the raw material procurement stage, the company strictly screens raw materials such as polymers, establishes a strict supplier evaluation system, and requires suppliers to provide detailed technical parameters of raw materials. Only raw materials that meet the production standards of high-quality waterproof fabrics can enter the subsequent production process, laying a solid foundation for the waterproof performance of fabrics from the source. ​
In the grey fabric stage after the fabric is woven, the preliminary waterproof performance pre-test is crucial. Using an international standard spray test device to simulate a natural rainfall scene, water droplets are sprayed on the surface of the grey fabric and observed for a period of time. If the water droplets roll off quickly and there is no obvious sign of penetration, it means that the grey fabric has a certain waterproof foundation; once water stains or penetration occurs, the company uses an electron microscope to conduct a microscopic analysis of the fabric structure, and immediately adjusts the weaving process parameters and raw material ratios in combination with parameters such as yarn twist and warp and weft density. Digital image processing technology is introduced to quantitatively analyze the contact angle and rolling speed of water droplets on the surface of the grey fabric, and establish a grey fabric waterproof performance database. This data-driven timely detection and adjustment mechanism provides accurate grey fabric conditions for subsequent key processes such as coating and lamination. ​
Coating and lamination processes are the core steps to give fabrics waterproof properties, and corresponding quality inspections are the key to ensuring the process effect. Colorful Fish Textile's dyeing and finishing production base is located in Shengze, Jiangsu. As a Chinese customized waterproof nylon taslon fabric manufacturer and wholesale waterproof nylon taslon fabric supplier, it can produce polyester and nylon fabrics covering a variety of processes such as coating, printing, TPU bonding, and hot stamping. After the coating process is completed, hydrostatic pressure testing becomes an important means to evaluate the waterproof performance of fabrics. The company uses a professional hydrostatic pressure tester to fix the fabric on the test instrument, gradually increase the water pressure, and use a high-definition camera to record the surface changes of the fabric in real time. The water pressure value when the first drop of water leaks from the fabric is used as the judgment standard. Strict grading standards are set for different types of waterproof fabrics to ensure that the products are suitable for various usage scenarios. ​
For fabrics with laminated waterproof and breathable membranes, breathability testing is indispensable. Breathability is related to the comfort of wearing fabrics. Using the cup method breathability test, the fabric is covered on a breathable cup filled with water. Under standard conditions, the amount of water vapor that passes through the fabric for a certain period of time is continuously measured with a specific pressure difference. Companies formulate corresponding water vapor transmission rate standards based on the different uses of fabrics. Only fabrics that pass the dual inspection of hydrostatic pressure test and breathability test can enter the next production link, thereby ensuring that the fabric has both strong waterproof ability and good breathability and comfort. ​
The finishing processes such as dyeing and printing of fabrics also have the risk of affecting waterproof performance. Colorful Fish Textile has set up a re-inspection mechanism in these links. The rain test simulates the actual long-term rain condition. The fabric is placed under a specific rain device and tested for a period of time at a certain rainfall intensity to check whether the fabric surface leaks and whether water stains spread. If the waterproof performance decreases, the company uses professional instruments to analyze the chemical agent components used in the dyeing and printing process to determine whether there are substances that react chemically with the waterproof coating or membrane. Once a problem is found, the process parameters will be adjusted immediately or the agent formula will be optimized to ensure that the post-finishing process does not damage the waterproof performance of the fabric. At the same time, the company will also conduct a wash resistance test on the fabric to simulate the daily washing scene, and conduct a waterproof performance test again after multiple cycles of washing to ensure the durability of the fabric's waterproof performance. ​
In addition to special tests for waterproof performance, a number of comprehensive performance tests are also included in the quality inspection system. The wear resistance test uses a professional wear resistance instrument to simulate the friction of the fabric in actual use, and the wear resistance of the fabric is tested by weighing method to calculate the mass loss rate of the fabric. Because poor wear resistance can cause the surface waterproof coating or membrane to wear easily, thereby reducing the waterproof performance, the company stipulates that the mass loss rate of the fabric must meet certain standards. The tear resistance test applies tension through professional equipment to detect the fabric's ability to resist tearing. For fabrics of different uses, corresponding tear resistance strength standards are set. Only fabrics that pass various comprehensive performance tests will be judged as qualified products and enter the finished product packaging and delivery stage. In addition, the company will also conduct color fastness tests on the fabrics, including color fastness to friction, color fastness to washing, color fastness to sunlight, etc., to ensure that the color of the fabric is stable in complex outdoor environments and does not affect the appearance and performance of the product. ​
Colorful Fish Textile also conducts sampling tests on finished fabrics and simulates actual use environments and scenarios for long-term testing. The sampled fabrics are made into outdoor clothing or equipment samples. In the environmental simulation laboratory, extreme temperature changes, humidity fluctuations, and strong wind environments are set up to conduct long-term waterproof performance monitoring and breathability performance monitoring. The humidity and temperature data on the surface of the fabric are collected in real time through sensors, and a fabric performance change model is constructed using big data analysis technology. This long-term test can truly reflect the waterproof performance of the fabric in actual use, and timely discover potential quality problems and improve them. At the same time, the company actively collects customer feedback, establishes a customer satisfaction survey system, regularly collects customer evaluation data on fabric performance, and continuously improves the quality inspection system and production process based on market demand and customer opinions. ​
Colorful Fish Textile relies on strong production strength, advanced production technology and a complete quality inspection system to strictly control the entire process from raw material procurement to finished product delivery. Through a series of scientific and rigorous testing methods such as hydrostatic pressure test, breathability test, rain test, abrasion resistance test, tear resistance test, as well as strict control of comprehensive performance such as color fastness and water washing resistance, it ensures that the waterproof performance of each batch of functional outdoor waterproof fabrics reaches the industry-leading level, providing high-quality fabrics for various types of clothing such as casual jackets, sportswear, outdoor protective clothing, down jackets, cotton clothes, ski suits, etc., to meet the increasingly diverse needs of customers. The company also actively participates in the formulation of industry standards, promotes technological progress and quality improvement in the functional outdoor waterproof fabric industry, and has won the trust and cooperation of many well-known clothing brands at home and abroad with high-quality products and excellent services.
