Streaks and Bars in Textile Fabrics Due to Yarn Differences and Technological Reasons,lly illustrated in Fig. 173 and 174. However, luster differences between more or less intensively twisted yarns can lead to differences in lightness . There are several possibilities for macroscopic and/or microscopic detection of yarn differences:Phenothiazines 发表于 2025-3-23 17:28:17

Fundamentals and Priming,has different effects and greatly reduces the serviceability of the textiles. Usually the cause of damage cannot be determined by purely visual evaluation. Textile microscopy, in contrast, often provides exact results within a very short time, which can be decisive in the correction of future produc可商量 发表于 2025-3-23 23:25:57
Chemical Damage,om this, structural abnormalities, i. e. damage, can be detected quite easily under the microscope. Staining reactions with Cotton Blue-lactophenol , Neocarmin W (Fesago, Heidelberg) or Pauly reagent simplify the recognition of wool damage. With Cotton Blue-lactophenol, damaged wool fibers流出 发表于 2025-3-24 05:09:05
Mechanical Damage,recognized in a later finishing stage when large quantities of material have already been damaged. Natural fibers and cellulose regenerated fibers are more susceptible to mechanical damage than synthetics; however, synthetics also suffer damage.一个姐姐 发表于 2025-3-24 10:28:34
Thermal and Thermo-Mechanical Damage to Synthetics,ent in the thermoplastic range cannot be avoided during manufacturing, finishing and garment production. Irreversible damage can only be prevented if the softening range of the fiber polymers is considered thoroughly. In addition, synthetics can suffer irreversible deformation during all processes w要控制 发表于 2025-3-24 12:30:48

Other Defects in the Quality of Textiles,ng causes which (as experience shows) can almost certainly be detected by microscopic examination. In practice, other defects occur which can be caused by various chance events. To determine the causes of these defects in finished textiles, considerable experience, a “criminalistic” intuition and th不可侵犯 发表于 2025-3-24 23:35:42
