Third phase structure of heat treatment monofilaments and bending behaviour

In this paper a detailed analysis of morphological structure of monofilaments of LLDPE. after heat treatment, is presented. The most discussed property for long standing is resilience of monofilaments. Therefore the pa/ter it will be focused on the behaviour of monofilaments. The production line of monofilaments was similar to the industrial one. For a detailed sti/ctural analysis are employed three different methods of morphological investigation: DSC, X-ray and Raman. For long term behaviour of monofilaments the dynamic bending test is performed. Based on the obtained results the behaviour of heat treatment samples ivac improved. This was explained by the increase of the amount of Gauche and Trans structure on the third phase

Drape of Composite Structures Made of Textile and 3D Printed Geometries

Applications of 3D printing in the fashion industry have continued to attract interest from academia and industry in order to improve and add functionalities to products. Among these applications, an interesting one is 3D printing on textile fabric. Composite structures created by 3D printing and textile fabric change a drape by improving or worsening its appearance. The scope of this work is to evaluate the effect of various 3D printed geometries on textile fabric regarding fabric drapes. The drape coefficient of the created composite structure is evaluated using a drape tester built according to EN ISO 9073-9. The results taken are compared with an algorithm developed for determining drape parameters and 3D form representation using color digital images and their image histograms. The measured values of the drape coefficient are close, with a minimal difference, up to 4%. The 3D printed patterns show a significant effect on the drape coefficient of textile fabrics by depicting another way to modify fabric drapes and create complex shapes by using less material. This can be seen as an advantage in the fashion industry where complex geometries can be added to textile fabrics, while changing fabric drape and product personalization and adding functionalities for garments and technical textiles

Influence of Heat Treatment on the Bending Behaviour of LLDPE Monofilaments

It is known that artificial turf surfaces based on LLDPE monofilaments have the potential to replace natural turf surfaces used for several sport surfaces. Even though the production parameters have a strong influence on the behaviour of monofilaments and indirectly on the final product, the effect of heat treatment at different stages of the production lines is not studied in detail. Therefore, the influence of heat treatment during the production of monofilaments was investigated. This investigation includes a study of the mechanical properties such as tensile testing and bending behaviour and morphological analyses by employing DSC measurements. The results show that the applied heat treatment has a strong influence on the bending behaviour even though the classical studied morphology structures do not show significant changes. Heat treatment influences quite importantly the characteristics of the non-crystalline part of the monofilaments and results in better long-term properties, such as resilience, deformation recovery and fibrillation resistance
