The strength of the textile bonded seams was analyzed. Two or more fabric layers joining are based on use of base layers structural properties and thermoplastic properties of adhesive film used for bonding. Five commercial produced fabrics of different structure (woven, knitted, laminate) and fiber content (polyester, cotton, flax) were used in this experiment. Thermoplastic polyurethane film was transferred from the base of silicone to fabric using 160 °C temperature and 10 seconds pressing duration. Fabric layers were bonded using 180 °C temperature and 30 seconds pressing duration. The strength of textile bonded seams was investigated using four different bond types, in order to determine method suitable for the analyzes of bonded seams of knitted fabrics and method suitable to analyze woven fabrics.
The woven fabrics structural mobility has some influence on the garment design and pattern construction. Deformation peculiarities during six textile fabrics extension were analysed in this work. Four of the tested fabrics had the elastane filaments in their structure. The method of parallelepiped shaped specimen uniaxial extension till fixed strain was used. The experiment was carrying out using a "Tinius Olsen HT10" tension machine. The specimens' deformation exceeds 14 %. The parallelepiped shape of specimen's was received by cut of its top and bottom edges with pitch of 16 degrees. The woven fabrics structure mobility was analyzed using strain-stress curves, numerical and graphical results. The results of this research work have shown that deformation peculiarities of the woven fabrics depend on their structural characteristics: density, thickness, wave and presence of elastane filaments. Taking into account the more considerable extensibility of elastane fibre the shearing phenomenon was not occurred finally during specimens' deformations. The results indicated that for the tested fabrics deformation till stated degree the force from 0.6 N till 9.4 N is necessary.
Presents the results of tests to determine the mechanical stability of textile fusing systems using two instruments: pulser ERDT‐3 and rotary‐rolls set‐up ARRV. The pulser ERDT‐3 allows textile systems in different testing conditions to be fatigued; one‐sided and double‐sided loading. Using instrument ARRV the specimen is not only fatigued in repeated one‐axed loading, but at the same time, its surface is abraded. Determines the relations between fusing conditions, fabric properties and glue line texture under different mechanical treatments. Proves that pressure increase allows a comparatively sufficient initial bond strength of textile systems forum, but this bond proves unstable under mechanical treatment.
Undesirable effect of asymmetric drape often occurs when cutting patterns of flared skirt on cross. Out of this reason garment seams twist toward the front or back or folds form different shapes on each side of the garment and this lowers garment aesthetic appearance. The new measuring procedure for asymmetric skirt drape near the side seam, based on bottom traces geometry, was developed in this paper. The experiment with four‐gored skirts of six lightweight fabrics was made. It was found that asymmetric drape depends on combination of grain lines directions of front and back panels of a skirt. There were made general conclusions relating skirt asymmetric drape with various fabric characteristics, such as bending rigidity, extensibility, shear rigidity, fabric weight and drape coefficient in this article. According to developed measuring procedure a final objective evaluation of skirt asymmetric drape rate will be done further.
