One of the ways to provide new functionalities for a textile product is the insertion of natural ingredients into the process of its manufacture. One of methods for formation multifilament yarns is melt spinning. During melt spinning process is possible to use additives on/in polymer and to form multicomponent yarns with various functionalities. Melt spun yarns are ideal for application in medicine field [1,2].
Polylactide (PLA) polymer is produce from synthesized nonpetroleum sources (most often from corn). It has good biocompatibility, biodegradability by enzymes and hydrolysis under physiological conditions, and antibacterial activity. Due it is used for medical products[3,4].
Natural resin as Myrrh is an aromatic gum resin obtained from a small tree. It is consisted of alcohol-soluble resins and volatile oil together with a gum soluble in water containing polysaccharides, proteins, and long chain aliphatic derivatives. The lipophilic part of myrrh is composed of steroids, sterols, and terpenes. Myrrh for a long time was used as a natural medicine and as an antibacterial material for wound dressing [5,6].The aim of the research is to investigate the influence of myrrh extract on PLA pellets on the melt spinning process and formed multifilament yarns mechanical properties at different multifilament yarns draw ratio.
It was estimated that melt spun multifilament yarns from PLA with myrrh extract have higher linear density, lower breaking force and higher elongation at break comparing with pure PLA multifilament yarns. The increase of draw ration cause the decrease of multifilament yarns linear density, decrease breaking force, increase elongation at break.

Silica-based coatings prepared by sol-gel polymerizing technology have been shown to exhibit excellent chemical stability combined with reducing the corrosion of metal substrates, showing promising use in aerospace and marine applications to protect light alloys. Moreover, this technology is an eco-friendly technique route for producing surface coatings, showing high potential for replacing toxic pre-treatment coatings of traditional conversation chromate coatings. This study aims to investigate the enhancement in corrosion protection of a hybrid-organic-inorganic silica-based coating cured at (80°C) by increasing the hydrophobicity to work on the aluminium 2024-T3 alloy. This approach involving a novel silica-based hybrid coating was prepared by introducing a 1H,1H,2H,2Hperfluorodecyltriethoxysilane (PFDTES) into the base hybrid formula created from tetraethylorthosilicatesilane (TEOS) and triethoxymethylsilane (MTMS) precursors; this formula was enhanced by introducing Polydimethylsiloxane polymer (PDMS). The corrosion protection properties of these coatings were examined by immersed in 3.5% NaCl with electrochemical impedance testing (EIS) and Potentiodynamic polarization scanning (PDPS). The chemical elements confirmation was done by infrared spectroscopy (ATR-FTIR); all this was supported by analyzing the surface morphology before and after the immersion by using scanning electron microscopy (SEM). The results of Electrochemical impedance testing analyses reveal the new open finite-length diffusion circuit element due to electrolyte media diffusion preventive by fluorinated groups. Also, it shows increases in corrosion protection arising from the increasing the hydrophobicity of the fluorinated coating compared to other formulas cured under similar conditions and bare Substrate. Additionally, the modified sol-gel exhibited improved resistance to cracking, while the increased hydrophobicity may also promote self-cleaning.

With the transition towards more sustainable paints formulations based on waterborne environment, their susceptibility for microbial contamination has to be better controlled in order to increase shelf life and functional lifetime. However, recent restrictions in European regulation on use of biocides have put limitations on the possibilities for traditional systems providing either in-can or dry-film preservation. The commercial technologies for in-can preservation that are currently available are based on 5-chloro-2-methyl-4-isothiazolin-3-one (CMIT) or 2-methyl-4-isothiazolin-3-one (MIT). At present, only limited number of alternatives can be used and are reviewed in this presentation. The examples of non-sensitizing biocidal components for coatings may include quaternary/cationic nitrogen amines, silver ion or zinc complexes. However, the use of the latter is not without risk for human health. Therefore, it is believed that disruptive methods will need to be implemented in parallel with bio-inspired solutions. In particular, the antimicrobial polymers, amino-acid based systems and peptides have similar functions in nature and can offer potential for antimicrobial activities. Also cross-border solutions currently applied in food or cosmetics industries need to be considered as examples that need be adapted for paint formulations. However, the incorporation in paint formulations remains challenging in respect of the stabilization and rheology control of the system. The overview in this work aims to provide different strategies and best evidence for future trends.

Hydrogels (HG) are 3D network of hydrophilic macromolecules linked by different "cross-linking points", which have as main advantage their capacity for the adsorption of large amounts of water without any apparent dissolution due to cross-linking. Thus, the hydrogels can undergo reversible swelling-shrinking process upon the modification of the environmental conditions (pH, ionic strength or temperature). This stimuli-responsiveness and their ability to entrap in their interior different types of molecules makes of them suitable platforms for drug delivery applications. Furthermore, HGs exhibit certain similarities to the extracellular tissue matrix and can be used as a support for cell proliferation and migration.
The interest of the interaction between biological systems and hydrogels in different applications has stimulated the interest for designing hydrogels with a homogeneous nanometric size that can be distributed within different organ and tissue, and used for drug delivery or biosensing. This work proposes to take advantage of the inner cavity of liposomes for fabricating hyaluronic acid hydrogel nanoparticles with a well-controlled size. For this purpose, liposomes obtained using the reverse phase [1,2] technique where loaded with hyaluronic acid molecules which then undergo a cross-linking to
form a hydrogel matrix with a well-controlled size define by the dimensions of the inner core of the template liposome (Figure 1). This makes possible to fabricate either liposomes-coated or nude hydrogel nanoparticles which may be exploited in different technological fields including cosmetic,
ophthalmology (dry eye disease treatment) or food science.

The microencapsulation method is an exhaustively used technique for phase change material (PCM) shape-stabilization. This technique has been used in a broad spectrum of applications such as building, medical, electronics, food, etc. Polymeric encapsulation is characterized with high toughness and good heat transfer property due to large surface area of capsules. In this paper, phenol-formaldehyde shelled PCM microcapsules (MPCM) were fabricated and their processing parameters were analysed with Taguchi method. Core to shell ratio, surfactant concentration and speed of mixing are the parameters which were optimized in five levels. The optimized values for surfactant concentration, core to shell ratio and agitation speed were 3%, 1:1 and 800 rpm. The obtained microcapsules were spherical in shape. The melting enthalpy of MPCM synthesized with optimized processing parameters was 148.93 J/g in the range of 35-62 ⁰C. The obtained temperature range of phase transition temperature can be used for storing different food articles such as chocolate and hot served foods.
