In today’s fashion and textile industries, the quality and performance of fabrics directly influence the market competitiveness of products. Especially in garment design, fabric appearance, hand feel, and durability are often important factors considered by customers when making purchasing decisions. Among the many factors affecting fabric performance, the wrinkle recovery property of textiles is undoubtedly one of the most critical aspects.Wrinkle recovery performance not only affects wearing comfort but also plays an important role in maintaining the overall appearance and aesthetic quality of garments. To accurately evaluate the wrinkle recovery ability of fabrics, the Fabric Wrinkle Bending Tester was developed and has become an essential advanced testing instrument in the textile industry.

Working Principle of Fabric Wrinkle Recovery Tester

I. Fabric Wrinkle Recovery Testing Principle

1. Fabric wrinkle recovery testing is the core testing function of this instrument. The test is mainly performed using the vertical folding, compression, and rebound recovery method. First, fabric specimens with standard dimensions, smooth surfaces, and no defects are cut according to the requirements of relevant standards. The specimen is then folded according to a unified procedure and placed steadily on the dedicated compression testing position of the instrument.

2. The equipment drives the compression rod downward at a uniform speed through a precision transmission mechanism, applying a standard constant pressure to the folded fabric specimen. The specified loading time is strictly maintained to allow the internal fiber structure of the fabric to form a stable wrinkle deformation under compression. After the pressure holding period is completed, the compression device automatically rises quickly to completely release the external force. The wrinkled fabric specimen then begins to recover naturally through the elastic recovery force of its own fibers.

3. The instrument is equipped with a high-precision photoelectric angle sensing system, which can accurately capture the real-time changes in the opening angle on both sides of the wrinkled specimen. It records the instant elastic recovery angle immediately after pressure release and the delayed elastic recovery angle after standing for a specified period of time. Based on the collected angle values, the system automatically calculates the fabric wrinkle recovery rate.

The larger the recovery angle and the higher the recovery rate, the stronger the wrinkle recovery ability and wrinkle resistance of the fabric. Conversely, fabrics with smaller recovery angles are more likely to wrinkle and have poorer ability to return to a smooth condition.

II. Fabric Bending Performance Testing Principle

1. In bending test mode, the instrument performs testing based on the principle of cantilever natural bending deformation. One end of the strip-shaped fabric specimen is firmly clamped and fixed, while the other end remains freely suspended. Under the influence of its own gravity, the specimen naturally bends and hangs downward.

2. Using a high-precision angle measurement component, the instrument accurately measures the bending angle formed by the free end of the specimen. Combined with basic parameters such as fabric weight per unit area, thickness, and specimen dimensions, the built-in standard calculation formula automatically converts the results into fabric bending stiffness, bending flexibility, and other performance indicators.

These results are used to evaluate the overall softness, stiffness, and drape performance of fabrics, clearly distinguishing the performance differences between soft skin-friendly fabrics and stiff structured fabrics. The test data provides reliable support for garment design and fabric selection.

III. Automatic Driving and Precise Positioning Principle

1. The instrument uses a stepper motor as the main power source and is equipped with a precision gear transmission structure. It ensures that both the downward compression speed and upward pressure release speed remain uniform and stable, avoiding impact forces that may damage the original fiber structure of the fabric.

The compression stroke, applied load, and pressure holding time can all be freely set and adjusted through the operation panel, allowing the instrument to flexibly meet the testing requirements of fabrics with different materials and different weights per unit area.

2. The angle measurement process eliminates the traditional manual angle measurement method and adopts non-contact photoelectric sensing detection technology. It is not affected by specimen color, texture, thickness, or other surface characteristics, providing high measurement accuracy and effectively reducing errors caused by manual reading.

The entire testing process, including specimen placement, automatic compression, timed pressure holding, automatic pressure release, angle acquisition, and data calculation, is completed automatically. This greatly reduces operational difficulty while improving testing efficiency and data accuracy.

IV. Data Calculation and Result Evaluation Principle

1. The equipment is equipped with an intelligent microcomputer control system with built-in calculation programs based on national and international standards. After testing, the system can instantly process and calculate the data, directly displaying multiple test results on the screen, including:

Instant elastic recovery angle

Delayed elastic recovery angle

Fabric wrinkle recovery rate

Bending angle

Bending stiffness

Other related test parameters

2. Operators can directly compare the test results with industry qualification standards and enterprise internal quality control requirements to quickly determine whether the wrinkle resistance, bending flexibility, and softness performance of the fabric batch meet the required specifications.

The equipment also provides functions such as data storage, result retrieval, batch statistical analysis, and printing output. These functions help testing personnel prepare test reports efficiently and provide clear and effective data support for process improvement and raw material selection.

The Fabric Wrinkle Bending Tester adopts a mature and stable working principle combining compression-induced wrinkle formation, elastic natural recovery, photoelectric angle acquisition, and intelligent data calculation. It can accurately and efficiently complete the dual evaluation of fabric wrinkle recovery performance and bending softness performance.The instrument completely replaces the traditional subjective manual evaluation method and realizes the digitalization, standardization, and systematic evaluation of textile fabric appearance and wear performance testing.With a reasonable structural design, simple operation, and accurate and stable testing performance, this instrument plays an essential role in various fields, including garment textiles, home furnishing fabrics, dyeing and finishing processing, raw material quality inspection, scientific research, and educational training.It can not only quickly determine the wrinkle resistance grade and softness grade of fabrics but also effectively guide manufacturers in optimizing weaving processes and finishing technologies, continuously improving fabric wearing performance and product quality.

Testing Methods and Application Fields of Fabric Wrinkle Recovery Tester

I. Testing Methods

The instrument provides two testing methods to meet the testing requirements of different types of fabrics:

1. Vertical Method

The fabric specimen is folded in half and vertically suspended. After removing the applied pressure and allowing the specimen to rest for a specified period of time, the recovery angle at the crease position is measured.

This method uses the natural effect of gravity to more realistically simulate the wrinkle resistance performance of heavy fabrics during actual use. It is suitable for evaluating the wrinkle recovery properties of thick and heavy fabrics.

2. Horizontal Method

The fabric specimen is placed horizontally. After completing the folding and compression process, the pressure is released, and the recovery angle of the crease is measured.

This method can minimize the influence of gravity on the test results and is more suitable for wrinkle recovery evaluation of lightweight and thin fabrics.

II. Application Fields

1. Textile Manufacturing Industry

Throughout the entire textile production process, the fabric wrinkle tester helps enterprises accurately identify potential wrinkle-related issues caused by seam processing, cutting processes, sewing operations, and other production procedures.
