| Types/Additive/Composite Material | Processing Technology | Fabric Characteristic | Reference |
|---|---|---|---|
| Yellow colorant (Buddleja officinalis) | traditional techniques of dyeing from communities of Yunnan, China equipped with natural mordant treatment | Optimum dying achieved at pH 5, 60 °C for 90 min. Natural mordant treatment improved the yellowness and color fastness was maintained, indicating a good combination process between natural mordant treatment and natural yellow dyeing. | [78] |
| Graphited knitting hemp fabric (GKHF). | Furnace filled with a nitrogen atmosphere, heating at 800 °C | GKHF showed a great air permeability, water vapor and moisture, as well as remarkable static stability in the range of 0.5 to 480 KPa.GHKF detected a variety of static pressure and physiological signals for health monitoring, rehabilitation, and convenience sport stuff. | [79] |
| Feretiko hemp fiber (woven) | Thermal comfort evaluated by thermal manikin | Clothing insulation of Feretiko was 0.20, very close to ASHRAE standard 55-2013 for clothing insulation of a long-sleeve (0.25 clo). The air permeability was also high (2600 L/m2 s). | [80] |
| Hemp fabric and epoxy resin composite | Composite technology: plate and Impregnated Fiber Bundle Test (IFBT) | The pores of composite are low observed in tomography with the similar fiber volume for all the composite. Untwisting reduced the tenacity at break of the rovings. Low-twisted rovings of composite resulting in similar tensile strength of best flax in the range of 150–200 MPa. | [81] |
| Hemp fabric and vinyl ester composite | Chemical treated woven hemp fabric: NaOH and fire retardant (FR) | The treatment increase weight, thickness, density and yarn crimp, while decreased mechanical properties of woven fabric due elimination of hemicellulose and lignin by NaOH and hydrolyzation of cellulose by FR.The treatment increased thermal stability and limiting oxygen index values indicating fire retardant properties was improved. | [82] |
| Hemp fiber, Lyocell and PLA composite | Wrap spinning process | Lyocell addition improve tensile strength of hemp/PLA composite-based fabric and lesser fiber pull-outs appears, but did not affect on water absorption. | [83] |
| PLA | Compression molding technique | Reinforcement improved flexural and charpy detected for fibre volume fraction of 20 and 30%, and decreased at 40%. The impact strength increased by increasing reinforcement content. 30% reinforcement showed the best creep behavior | [84] |
