Automatic Measurement for Fabric Surface Shapes with Two-Dimen-sional Fourier Transform Profilometry

Two- dimensional Fourier transform profilometry (2 -D FTP) for data acquisition of fabric surface shapes isproposed. Phase unwrapping technique based on digitalweighted filter and reliability mask are employed. Ex-perimentai results of shape measurement for several fab-ric appearances are given. From the measured results, itis shown that this method can make up for not only thedisadvantage of the gray level image analysis which isonly suitable for simple structure and solid - pattern fab-ric, but also the low speed and high cost of laser dotscanning technique.

Optical Properties of Fluorescent Dyes

Fluorescent dyes have been widely used these years. Because of the special optical performance, conventional CCM systems seem to be unable to predict the recipes of fabrics dyed with fluorescent dyes. In order to enhance the functions of CCM systems, the optical properties of fluorescent dyes in their absorption region were investigated. It has been found that there was a fixed maximum absorption wavelength for each fluorescent dyes whatever its concentration is. Both absorption region and maximum absorption wavelength of the dyes in solution are the same to those in fabric, and that the absorption is directly proportional to the concentration of the dye. So the optical properties obtained in solutions cna be applied for describing the optics performance of fluorescent dyes in fabrics.     

染色真丝织物的柠檬酸防皱整理

分别采用柠檬酸、2D树脂、柠檬酸／三乙醇胺整理真丝织物，分析了它们对真丝织物折皱回复角、染色牢度、服用性能及色差值的影响程度，同时分析了添加剂三乙醇胺的作用．结果表明，三乙醇胺能增加织物对阴离子染料的亲和力，明显改善整理织物的变色；可以提高真丝织物的湿折皱回复角，真丝织物的强力损失也得到降低．
