Abstract

The article presents an overview of electrospinning process development from the first investigations in the field of behaviour of liquids in an electrostatic field to the electrospinning methods and investigations in the 21st century. The article presents the history of electrospinning process development, the main problems that are solved, and also indicates the gaps in the field of standardisation of nanofibrous web structure measurement and estimation. There are a lot of works in which authors analyse influences of various parameters on the electrospinning process or on the structure of electrospun web, whereas the majority of them do not analyse the quality of structure using mathematical criteria. Such a situation leads to different conclusions and makes it impossible to compare various works by different authors. Despite numerous studies in electrospinning, investigations in the electrospun nanofibrous web estimation are not sufficient. Until now, a unique standard method for measuring and estimating the fibre diameter and web porosity has not been developed. The necessity of such a method and standards is obvious, and the lack of such a standard could have a negative influence on the electrospun product introduction into the market.

Abstract

Nine different face-to-face cut pile carpets were used for the investigation. The raw material of the carpet pile yarns was wool and polyamide blended yarns. The influence of the different structure parameters (carpet pile density and pile height) on the carpet properties was investigated. The deformations occurring in carpets during compression were determined. A compressive load of 100 N was applied to the surface of the carpets, and three cycles of loading were performed. An orthogonal mathematical plan was used to investigate resulting deformations. As regards the total deformation, results showed that both of the structure parameters of the carpets have an influence in elastic deformation pile density is the parameter which has the biggest influence, and in unrecovered deformation both of the structure parameters have a great influence.
