The article contains basic information about the materials applicable to the production of biodegradable polylactide (PLA) fibers and methods of fiber-forming polymer. The article presents the most important physico-mechanical and physico-chemical characteristics of polylactide fibers application. Lengthwise and transverse fibers views are presented and microscopic view of the melting of PLA fibers. Source

In this article new testing procedure, developed in Laboratory of Chemical Testing and Instrumental Analysis of Textile Research Institute, is presented. Inspiration to devise new testing procedure were problems with identification of new (textile) raw materials and already produced but chemically modified texlites. Developed testing procedure was carried out in Laboratory during statutory action of Textile Research Institute. This work was also realised as an action to look ahead problems reported by Clients.

The article is a continuation of the publication: "The analysis of the possibility of formation of component yams pneumatically linked with metallized components", which was published in Textile Review, Textiles, Garments, Leather, No 7/2012 [1] and presents metrological test results on selected parameters of component yams formed by pneumatic texturing and interlacing technique with metallized elements. Moreover, the publication contains results of the analysis of processing obtained yams in the knitting process. Source

The publication contains the tests results on structure of component yarns formed by air interlacing technique, implemented using computer image analysis (microscopic examination). Source

Introduced in 2000, Directive 2000/53/EC of the European Parliament and the Council of Europe prohibits the use of heavy metals such as lead, mercury, cadmium and chromium VI in the textile materials used in cars. Therefore, there is a need to monitor the content of these materials in vehicles having ended their life-cycle. The reason is the high toxicity of the analysed metals. In order to monitor the level of metals contained in the upholstery a series of experiments using ASA and UV-Vis was performed. Based on the performed investigations own test procedure was developed and validated, concerning the determination of heavy metals (PB, Hg, Cd, CrVI) in samples of automotive textiles. Source
