Abstract [en]

Wear resistance of conductive Poly Lactic Acid monofilament 3D printed onto textiles, through Fused Deposition Modeling (FDM) process and their electrical conductivity after abrasion are important to consider in the development of smart textiles with preserved mechanical and electrical properties. The study aims at investigating the weight loss after abrasion and end point of such materials, understanding the influence of the textile properties and 3D printing process parameters and studying the impact of the abrasion process on the electrical conductivity property of the 3D printed conductive polymers onto textiles. The effects of the 3D printing process and the printing parameters on the structural properties of textiles, such as the thickness of the conductive Poly Lactic Acid (PLA) 3D printed onto polyethylene terephthalate (PET) textile and the average pore sizes of its surface are also investigated. Findings demonstrate that the textile properties, such as the pattern and the process settings, for instance, the printing bed temperature, impact significantly the abrasion resistance of 3D printed conductive Poly Lactic Acid (PLA) onto PET woven textiles. Due to the higher capacity of the surface structure and stronger fiber-to-fiber cohesion, the 3D printed conductive polymer deposited onto textiles through Fused Deposition Modeling process have a higher abrasion resistance and lower weight loss after abrasion compared to the original fabrics. After printing the mean pore size, localized at the surface of the 3D-printed PLA onto PET textiles, is five to eight times smaller than the one of the pores localized at the surface of the PET fabrics prior to 3D printing. Finally, the abrasion process did considerably impact the electrical conductivity of 3D printed conductive PLA onto PET fabric.

Abstract [en]

Adhesion of conductive poly-lactic acid filament (PLA) 3D printed onto polyethylene terephthalate (PET) fabrics is a one of the fundamental properties to guarantee their use in smart textiles field. The conductive PLA layer is made of carbon black (CB) incorporated into PLA polymer prior to extrusion process. It is commonly known that due to the low surface tensions of polymeric materials, 3D printed conductive PLA onto PET textiles possess poor adhesion. Therefore, an improvement of this property, even already approached by some researchers (1–6), is still highly required. In this research work, a pre and post-treatments were applied to significantly improve the adhesion strength at the interface polymeric layer/textile compared to former techniques used in other researches such as plasma treatment; coating of glue stick, washing and ironing processes. The pre-treatment consists in grafting acetic acid by UV curing onto both PET fabric and PLA filament through digital printing and deep coating respectively and then applying a solution pressure sensitive adhesive (PSA) on the fabric via digital printing. After 3D printing process on textiles, heat and pressure were applied on the materials using a heat press to chemically bond the PLA layer to the PET fabric. The findings are very promising as they demonstrate the possibility of significantly improving the adhesion of thermoplastic polymer 3D printed on textiles for smart textiles applications. Compared to other alternative solutions, these findings can potentially be implemented, in the future, by using 3D printing technology for pre-treatment and printing processes followed by thermo-compression technique for complete chemical bonding.

Purpose

This paper aims to evaluate and simulate the impact of the build platform temperature of the three-dimensional (3D) printer, the structure and heat transfer of textiles on the adhesion and durability after washing properties of 3D printed polymer onto textile materials using thin layers of conductive and non-conductive extruded poly lactic acid monofilaments (PLA) deposited on polyethylene terephthalate (PET) woven fabrics through fused deposition modeling (FDM) process.

Design/methodology/approach

Prior to FDM process, thermal conductivity, surface roughness and mean pore size of PET woven fabrics were assessed using the “hot disk,” the profilometer and the capillary flow porometry methods, respectively. After the FDM process, the adhesion and durability after the washing process properties of the materials were determined and optimized based on reliable statistical models connecting those properties to the textile substrate properties such as surface roughness, mean pore size and thermal conductivity.

Findings

The main findings point out that higher roughness coefficient and mean pore size and lower thermal conductivity of polyester woven textile materials improve the adhesion properties and the build platform presents a quadratic effect. Additionally, the adhesion strength decreases by half after the washing process and rougher and more porous textile structures demonstrate better durability. These results are explained by the surface topography of textile materials that define the anchorage areas between the printed layer and the textiles.

Originality/value

This study is for great importance in the development of smart textiles using FDM process as it presents unique and reliable models used to optimize adhesion resistance of 3D printed PLA primary layer onto PET textiles.

Abstract [en]

Although direct deposition of polymeric materials onto textiles through 3D printing is a great technique used more and more to develop smart textiles, one of the main challenges is to demonstrate equal or better mechanical resistance, durability and comfort than those of the textile substrates before deposition process. This article focuses on studying the impact of the textile properties and printing platform temperature on the tensile and deformations of non-conductive and conductive poly lactic acid (PLA) filaments deposited onto polyethylene terephthalate (PET) textiles through 3D printing process and optimizing them using theoretical and statistical models. The results demonstrate that the deposition process affects the tensile properties of the printed textile in comparison with the ones of the textiles. The stress and strain at rupture of the first 3D printed PLA layer deposited onto PET textile material reveal to be a combination of those of the printed layer and the PET fabric due to the lower flexibility and diffusion of the polymeric printed track through the textile fabric leading to a weak adhesion at the polymer/textile interface. Besides, printing platform temperature and textile properties influence the tensile and deformation properties of the 3D printed PLA on PET textile significantly. Both, the washing process and the incorporation of conductive fillers into the PLA do not affect the tensile properties of the extruded polymeric materials. The elastic, total and permanent deformations of the 3D-printed PLA on PET fabrics are lower than the ones of the fabric before polymer deposition which demonstrates a better dimensional stability, higher stiffness and lower flexibility of these materials.

Abstract [en]

In this study, conductive tracks are integrated onto textiles through Fused Deposition Modelling (FDM) process and the correlation between the FDM process parameters, the textile properties (the porosity and the structure for instance) and the electrical resistance of the composites is investigated. Many researchers have studied the electrical conductivity of polymers composites using incorporation of conductive fillers such as carbon black or carbon nanotube–polymer composites and the effect of the 3D printing process parameters, such as extruder temperature, on the electrical properties [1–7]. However, in this paper, in addition to study and understand the electrical properties of these conductive materials deposited onto textiles, they are maximized to guarantee the use of the textile composites in smart textiles field.Findings are very promising and important in the development of functionalized textiles as they demonstrate the feasibility of enhancing the electrical conductivity of textile composite materials through theoretical models based on the experimental data.

Abstract [en]

FDM technology used for printing functionalized layers on textiles brought new challenges such as the understanding and the improvement of the adhesion performance of the thermoplastic filaments on synthetic textile materials. In addition to the impact of printing parameters, the correlation between the heat transfer and structure of the textile material and the adhesion performance after varying printer platform temperature was an important parameter considered in this paper. A factorial design, using material density, direction, and structure and platform temperature as factors, was followed. 3D-printed materials made of PLA filaments deposited on polyester woven and knit materials were manufactured on a dual-head printer and their adhesion was measured according to DIN EN ISO 13937-2 and ISO 11339 and the heat transfer of the fabrics according to ASTM D4966-98, ISO 6330 and ISO 22007-2. The findings showed that the heat transfer and structure of textile materials affect the adhesion properties of the 3D-printed material.
