Considering the quality and service emphasized by Jieli Textile Co., Ltd., how do they ensure that the quality of the Polyester Yarn used meets high standards and how do they integrate it into the quality control system of the entire production process?
1. Selection criteria for polyester yarn
Raw material quality: Jieli Textile has established long-term cooperative relationships with well-known domestic and foreign Polyester Yarn manufacturers to ensure that the purchased polyester yarn raw materials are of reliable source and good quality. They require suppliers to provide raw material certificates that meet international standards, including but not limited to environmental certification, strength test reports, abrasion resistance test reports, etc., to ensure that the raw materials are of high quality at the source.
Physical properties: When selecting polyester yarn, Jieli Textile will strictly evaluate its physical properties, including breaking strength, breaking elongation, abrasion resistance, resilience, etc. These properties directly affect the strength, durability and feel of spunlace non-woven fabrics, so they must meet or exceed industry standards.
Chemical stability: Polyester Yarn needs to have good chemical stability and be able to resist acid and alkali corrosion, oxidation and ultraviolet radiation to ensure the stability and service life of spunlace non-woven fabrics in different environments.
Environmental protection requirements: With the improvement of environmental awareness, Jieli Textile will also consider the environmental performance of polyester yarn when selecting it, such as whether it contains harmful substances, whether it is recyclable or biodegradable, etc. They tend to choose polyester yarns that meet environmental standards and have little impact on the environment.
2. Quality control system
Raw material inspection: All purchased Polyester Yarn will undergo a strict inspection procedure before entering the warehouse, including appearance inspection, physical property testing and chemical analysis. Only polyester yarns that meet the company's standards will be allowed to enter the production line.
Production process control: During the production process, Jieli Textile uses advanced production equipment and processes to ensure that the polyester yarn maintains stable quality during processing. At the same time, they will monitor and record each link in the production process in real time, including yarn tension control, temperature control, humidity control, etc., to ensure the consistency and stability of production conditions.
Online quality inspection: On the production line of spunlace non-woven fabrics, Jieli Textile has set up multiple quality inspection points to conduct real-time inspection of semi-finished products in the production process. This includes the testing of yarn uniformity, strength, elongation at break and other indicators, as well as the testing of spunlace non-woven fabrics' thickness, air permeability, water absorption and other properties. Once quality problems are found, measures are taken immediately to make adjustments and improvements.
Finished product inspection and testing: All spunlace non-woven fabrics that have been produced will undergo strict finished product inspection and testing before leaving the factory. This includes appearance inspection, size measurement, physical property testing and chemical analysis. Only products that have been fully tested and meet the company's standards will be allowed to be sold from the factory.
After-sales service and feedback: Jieli Textile attaches great importance to customer feedback and after-sales service. They have established a complete customer service system to collect and handle customer opinions and suggestions in a timely manner. For quality problems reported by customers, they will immediately investigate and handle them to ensure that the problems are solved in a timely manner and prevent similar problems from happening again.
3. Continuous improvement and innovation
Jieli Textile not only pays attention to current quality control, but also is committed to continuous improvement and innovation. They have established cooperative relationships with domestic and foreign scientific research institutions, universities, etc. to jointly develop new Polyester Yarn materials and technologies to improve the performance and application range of spunlace non-woven fabrics. At the same time, they also regularly evaluate and improve the existing quality control system to ensure that it always meets the changes in industry standards and customer needs.
