Abstract
Purpose
Production and consumption of textile garments contribute significantly to environment problems. The purpose of this paper is to perform the evaluation of textile waste generated at Lithuanian clothing enterprises based on statistical data analysis and business cases studies.
Design/methodology/approach
For the evaluation of real situation of waste generation in companies, an original methodology was developed and used during investigation. In order to get an overall view, statistical data of waste generation and management in Lithuania were also analysed. Waste accounting covered data such as wastes from unprocessed textile fibres and wastes from processed textile fibres and textiles (not otherwise specified).
Findings
The investigation showed that the amount of cutting waste reaches 20-25 per cent of the total quantity of materials used for production. It was found that the waste is not sorted in Lithuanian clothing enterprises and is disposed in landfills in most cases, notwithstanding the positive tendencies of recycling of waste that were observed during past year. However, a practical recycling strategy and broader perception of developing products with greater added value from waste are missing in Lithuania.
Originality/value
In this research, a simple methodology was developed for determining the quantity of the textile waste generated by enterprises, the introduction of which would allow us to expect better results in waste accounting and management. The results of investigation are useful to gain in-depth understanding of waste generation in various countries.

Abstract
Purpose
The purpose of this paper is to determine the influence made by complex finishing of denim fabrics, i.e. laser treatment and industrial washing, on the change in tension properties of fabric.
Design/methodology/approach
Test specimens were treated by a laser JG-10050. Lasers main technological parameters: maximum laser beam power is 65 W, laser types are hermetic and detached CO2, laser tube wavelength is 10.62 µm. The test specimens processed by different laser energy density have been exposed to industrial washing and their tensile characteristics have been investigated.
Findings
The results of the research have demonstrated that complex finishing reduces the breaking force; however, material extensibility remains almost unchanged. Mechanical behaviour and composition characteristics of fabric are determined both by laser motion direction in respect of warp or weft and laser energy density.
Originality/value
The carried-out analysis of scientific literature has shown that the effect of laser on the fabric surface is relevant both in scientific and practical terms: the scientific literature contains studies on absorptive properties of laser treated materials; however, the behaviour of materials after complex finishing has not been widely investigated thus far.

Abstract
Purpose
To produce a coated fabric, a base fabric may be completely or partially coated with a polymer layer, which changes the properties of the new system relative to the base fabric. The purpose of this paper is to analyze the influence of the thermal transfer material and its shape on the deformability of knitted fabrics during the uniaxial extension and to determine the residual deformation of the thermoplastic transfer element of coated fabrics after unloading.
Design/methodology/approach
Knitted fabrics were partially and entirely coated with heat transfer material. For partial coating, square pieces of three different transfer materials were bonded on the middle of the specimen. They were solid, perforated with either nine circular holes or six rectangular holes. A heat seal press was used to laminate knitted fabrics. The samples were subjected to uniaxial tensile testing. The characteristics such as strain at maximum force, strain at break, and strain at low stress were measured. After stretching and relaxation of the specimens, the residual deformation of the heat transfer element was also investigated.
Findings
The results indicated that coating knitted fabrics with transfer material may decrease their stretchability. The experiments show that the decrease in stretchability and in the degree of residual deformation after stretching and relaxing depend on the knitted structure, the shape of the transfer element, and the degree to which the fabric is coated.
Originality/value
This study examines the influence of heat transfer material which may be not only entirely but also partially joined with knitted fabric layer on the deformability and shape stability of this system.

Abstract
Purpose
The purpose of this paper is to investigate the non-uniformity of the surface where textile fabric systems were joined using embroidery with the help of the system dimensional scanning.
Design/methodology/approach
To ascertain and evaluate surface non-uniformity and puckering of the embroidered elements dimensional 3D laser scanner was used. The dimensional 3D model of the embroidered element was imported into the software package RapidformTM and returned to the beginning of the coordinate system for the puckering analysis and evaluation.
Findings
The obtained results have shown that when embroidering an element it is important to evaluate the direction of stitches with consideration to the fabric because when elements are performed in different fabric direction their quality can be different. The embroidered elements that were performed on more lightweight fabrics have bigger surface non-uniformity. The greatest inadequacy of shape and dimensions in the embroidered element was found for materials with the smallest value of surface density, closeness of texture and the smallest indicator of fabric surface filling.
Originality/value
The proposed approach can be adjusted to investigate surface non-uniformity of embroidered elements.
