Abstract
Purpose
The purpose of this paper is to predict the pull-out force of loop pile of ramie/cotton terry woven fabrics treated with aroma-microcapsules as well as to understand and to interpret the pull-out behaviour developing the mathematical model.
Design/methodology/approach
The displacements and forces associated with pulling a yarn from different structures of fabrics were determined. Regression analysis and factorial designs were performed.
Findings
The yarn pull-out behaviour of terry fabric is highly dependent on the applied treating and demonstrated various extents of variability under the different pulling distances. The character of yarn pull-out is periodic and depends on fabric construction. The difference between the resistance to pile loop extraction for the grey and modified terry fabrics depends on the changed fabric’s structure. The existence of good relation between binder’s concentration and resistance to pile loop extraction of terry fabric was proved.
Practical implications
The study enables to forecast important loop feature for terry aroma-textiles: to be securely held in the place preventing loop pulling.
Originality/value
The assessment of the influence of fabric’s weft density and binder’s concentration for the yarn pull-out of terry aroma-textile was proposed. The research developed analysis and empiric mathematical equations suitable for predicting of displacements and forces related to pulling phenomenon as well as designing new multifunctional terry fabrics with resistance to pile loop extraction required. The received knowledge could enlarge the base of information needful for design of new products for clothing, home textile and healthcare/well-being applications as well.

Abstract
Purpose
The purpose of this paper is to propose the materials structure-wetting behaviour relationships and to show their peculiarities for some types of surgical woven fabrics and applications of liquids.
Design/methodology/approach
To show the effects of fabrics structure on wetting behaviour of surgical textile materials, the special structural indices in terms of yarns and filaments lateral area were used.
Findings
It was shown good correlation between total lateral area of filaments in unit area of woven fabrics and wetting contact angle of liquid drops on the tested samples. Probably due to different structure of woven fabrics at a level of fibres, another index, i.e. total lateral area of yarns in unit area of fabrics, is not suitable to show clear effect on wetting behaviour of the samples. The possibilities of applications of relationships for several types of textile materials and liquids were indicated.
Originality/value
To date there are no investigations concerning relationships between special structural properties of the surgical woven fabrics and their wetting behaviour. On a basis of the proposed approach into fabrics structure evaluation, this study developed analysis and some types of new equations for prediction of wetting contact angle of the materials.

Abstract
Purpose
The purpose of this paper is to investigate the physical properties of smart aromatherapic ramie/cotton terry fabrics containing microcapsules (MC) with essential Eucalyptus oil.
Design/methodology/approach
Terry fabrics are manufactured by changing the weft density. The air permeability is determined for grey and microencapsulated textile. The factorial designs are made. For informative experiment the linear type of regression is analysed. Development of physical properties of microencapsulated terry fabrics is discussed.
Findings
The air permeability of aromatherapic terry fabrics is determined. All statistical analysis is performed. Appropriate conclusions about the influence of fabric’s structure and microencapsulating process on terry fabric quality are made.
Originality/value
To date there are no investigations concerning terry textiles with fragrance MC. This study developed analysis and empiric mathematical equations suitable for evaluating and designing terry fabrics with the air permeability required. Assessment of the influence of fabric’s weft density and binder concentration for the air permeability of terry textile is proposed.

Abstract
Purpose
The purpose of this paper is to investigate the resistance to pile loop extraction of terry fabrics regarding the pile height and impact/finishing.
Design/methodology/approach
Fabrics are manufactured by changing the pile height and applying impact/finishing procedures. The resistance to pile loop extraction are determined. The factorial designs are made. For informative experiment the linear type of regression are analysed. Yarn pull-out behaviour in terry fabrics is discussed.
Findings
The dynamics of yarn pull-out process in terry fabrics is estimated through the force-pulling distance curves presented. The resistance to pile loop extraction is determined. All statistical analysis is performed. Appropriate conclusions about the influence of fabrics structure and impact/finishing on yarn pull-out process are made.
Originality/value
The study developed analysis and empiric mathematical equations suitable for evaluating and designing fabrics with the resistance to pile loop extraction ability required. Assessment of the influence of fabric's pile height and impact/finishing on the yarn pull-out is proposed.
