Hebei University Of Science And Technology Has Developed A Fabric Surface Hairiness Test System.

Textile is easy to form due to friction during finishing process.

These hairiness will not only make the finish of the fabric worse, but also affect the appearance and quality of the fabric, and bring a series of problems to the subsequent processing. Therefore, fabric hairiness becomes an important index for evaluating the fabric quality and processing effect.

However, the evaluation of fabric hairiness has always been lack of a scientific and accurate evaluation method. Generally, subjective observation is carried out by observer's crease visual observation method. The accuracy, reliability and repeatability of the observation results are very poor.

Appearance of fabric hairiness test system

In order to provide a convenient, accurate and scientific testing method and grading standard for fabric hairiness test and evaluation, the research team led by Professor Yao Jiming of Hebei University Of Science and Technology led the research of fabric hairiness testing system with a number of joint ventures for 5 years.

The system uses projection image processing technology, and uses parallel light to illuminate the creases on the top of the fabric to image on the projection screen. The optical image is converted into electrical signals by photoelectric conversion function, and processed and analyzed, so as to realize the rapid capture, calculation and characterization of the hairiness images, and the results are accurate and reliable.

Fabric hairiness capture image

The instrument is suitable for the evaluation of the singeing effect in textile processing; knitted fabrics and leisure.

Evaluation of biological polishing effect, evaluation of enzyme washing effect of cowboy clothing, evaluation of shrinkage degree of wool fabric, quality evaluation of textile fabric and so on.

(1) the average hairiness length per unit area (cm2) of the fabric.

Root number and hairiness distribution;

(2) comparison of hairiness rates among different samples;

(3) high resolution fabric hairiness imaging.

Software operation and result display interface of fabric hairiness testing system

Relying on the principle of this instrument, Hebei University Of Science and Technology was successfully approved.

The standard "testing method for textile fabric hairiness" and "drafting count method for textile fabrics" and the drafting unit of China spinning Union standard "surface hairiness length rating method for non pile fabrics", with a view to realizing the standardization of fabric hairiness detection methods and grading as soon as possible.
