Work outfits should protect the body against injuries and environmental hazards, meet technical requirements of the job and provide comfort for the wearer. Designing suitable work outfts based on the job technical requirements is an important issue which has not been addressed suffciently in Iran yet. This paper studies the design of suitable work outfts for Iranian female workers based on both performance in work and aesthetics. For this purpose, the fabrics were selected and used for preparation of the work outfts for female workers. Several workers tested the fnished outfts and evaluated them. The results showed a high level of satisfaction from the designed outfts as they were meeting all necessary technical requirements.

Bagging is a permanent three-dimensional deformation occurred in clothing that affects both the appearance and performance of garments considerably. The deformation depends on the properties of fbers, yarns, and fabrics. The study of bagging behavior and its measurement is one of the most critical stages of production and end-use of textiles. The present paper reviews the methods of bagging measurement in garments and discusses the effect of fabric structure (knitted, woven, or non woven) on bagging.

Negative Poisson's ratio materials or auxetic materials are fascinating materials, which expand laterally when stretched axially or shrink laterally when compressed. To date, a large number of materials with this characteristic have been discovered, made or investigated. These materials have unique properties which make them attractive for special applications. Till now, two general structures have been proposed which could be used either alone or in woven fabric structure. However, there are limited studies in the feld of auxitic woven fabrics. Several knitted structures with auxetic effect have been made from non-auxetic yarns. These fabrics have auxetic effect in limited range of tensile elongation. A number of auxetic 3D textiles have also been proposed for various applications.

Using phosphorescent pigments for protective clothes, and other guidance tools is considered in recent years. These pigments were being used in dyeing and printing processes in the past. Their most common issues were their high amount of wastewater pollution, insolubility in water, and long process time . Producing photoluminescent synthetic fbers by melt spinning is one method to tackle these issues. In this study, for producing the polypropylenen (PP) photoluminescent fbers, different amounts of phosphorescent pigment were added to PP before melt spinning. The as-spun fbers were then drawn to orient the fbers. Two different mixing methods were employed: (1) direct mixing the PP granules and phosphorescent pigment and (2) producing the phosphorescent pigment masterbaches and then mixing them with PP granules. The fber samples were analyzed with reflectance spectrophotometer to measure their afterglow time and tensile tester to measure their tensile strength and elongation at break. It was observed that the afterglow time and color saturation increased with increasing the amount of phosphorescent pigments in the PP fber matrix. On contrary, the mechanical properties of the fber samples decreased with increasing the amount of phosphorescent pigments.

Low temperature plasma technology has attracted the attention of several researchers as it is a fast and environmentally friendly method for surface modifcation of textiles. In this study, the effects of plasma treatment on physical and chemical properties of wool fbers including surface morphology, tenacity, surface functional groups and water wicking are reviewed. Due to the etching effect, cold plasma treatment can improve the hydrophilicity and dyeability of wool fbers. The effects of cold plasma treatment on dyeing of wool fbers with different synthetic and natural dyes have been also reviewed. Generally, the surface modifcation of wool fbers using oxygen, nitrogen and argon plasmas can improve the dyeability of wool fbers with anionic dyes. Furthermore, the color fastness properties of the plasma treated wool samples are improved compared with those of the untreated samples.

In recent years, jute fber reinforced composites have gained attention of many researchers due to their low cost, acceptable mechanical properties and biodegradability. To overcome the brittleness of these composite under mechanical loads, hybridization of jute with high tenacity polyester fbers has been investigated in this study. Hybrid composite samples with various weight percentages of polyester fbers were fabricated using hand lay-up method and subjected to low-velocity impact loading. The flexural behavior of the composites was then measured using three-point bending test for both the impacted and the non-impacted samples. The results showed that with increasing the weight percentage of polyester fbers, the flexural strength and modulus of the hybrid composites decreased. However, the extent of drop in flexural properties after impact was considerably lower. In fact, adding high tenacity polyester fbers to the composites increased their energy absorption capabilities under low-velocity impact loads.
