The study encompasses nine fabric variants with different numbers of knit and miss stitches in the repeat, alongside with half Milano rib fabric. All knitted fabrics are produced using a 2-ply 25x2tex x 2 cotton/flax blend yarn (70% cotton, 30% flax) on a 10 -gage flat-bed knitting machine. The comprehensive analysis encompasses crucial structural properties after dry relaxation for 10 days and after four washing cycles. Also, both the dimensional properties and stretch properties were examined b lengthwise and widthwise. It was found that the lengthwise dimensional changes for all fabrics were significantly greater than widthwise. The interlooping repeat significantly affects the widthwise fabric shrinkage: an increase in the percentage of missed stitches in the repeat leads to a decrease...

This information is important for compression socks, because it provides data regarding the relaxation processes of the textile product and of the human leg. In this work, changes of the body geometry after 1 and 4 hours with compression socks are investigated. Up to 9% changes of the cross section areas and up to 5.5% of changes of the circumference between the position at the starting point and after 4 hours are detected. Additionally the differences between the both legs of the investigated person and of the different (upper- and bottom) part of the leg are observed. It is the first step to the digitalization of the personal compression stocking design.

In this context, warp knitted structures were produced using different weft threads laying in. The elastic warp knitted fabric produced with transverse weft threads for the whole width was used as a reference sample. It is widely used in medical products. Laying in weft threads with a partial set according to a certain repeat allows us to get structures in which there is no connection in adjacent wales in certain places. This leads to the formation of through holes in the structure. As a result of increased permeability, comfort properties are improving. The structure, functional and comfort properties of developed and reference elastic warp knitted fabrics were investigated. It was found that novel elastic fabrics have higher values of comfort indicators and provide the necessary functional properties.

Compared to other textiles, elastic warp knitted materials, which have elastomer threads in each wale have been widely used in producing medical and preventive products. Thus, in order to decrease the weight and cost of these products without effect on fabric’s stretchability, in this study, various elastic warp knitted fabrics were produced using different raw materials and elastomer threading arrangements, and their properties were investigated. The fabrics were produced on a crochet knitting machine with five different arrangements of elastomer threading and four different laid-in yarn materials as polyester, cotton, and linen. Then the dimensional properties and elastic behaviors of the samples were determined and evaluated comparatively. Statistical analysis showed that all studied elastic warp knitted fabrics have high provide elasticity a...

In order to undertake the study of the influence of in-layed yarn positioning and of fillet interloping repeat different types of fillet warp knit fabrics with in-lay yarn were produced. The array of data for the various design options provide analytical tool for making comparisons about the mechanical properties of the warp knit fillet structures with elastomeric inlayed yarn. It is observed that the repeat of fillet interloping and the position of in-laying yarn have some effect on stretch characteristics of warp knit structures. It is a consequence of a different relaxation of inlayed yarn in structure. Elastic strain is the largest part of the full strain of warp knit fabric and the part of residual strain does not exceed 0.11

This increases the need for support and fixing of different spine parts, that promotes the demand growth of the binders and braces. Such special goods prevent the emergence and stop the disease development, improves the well-being condition and normal function of the body, the ability to maintain performance and activity. Despite the huge number of existing structures of therapeutic and prophylactic products, the elastic fabrics of different width are the basic materials for their manufacture. Therefore, the main attention is directed to the formation and investigation of the knitted elastic fabric for special purposes, especially for preventive goods The knitted fabrics with weft - inserted yarn that produced on crochet knitting machine is the subject of this research. The chain is the basic interlooping of all variants. An elastomeric thread is i...

Компресійна терапія є засобом лікування венозних виразок гомілки, венозної гіпертензії, венозного набряку, венозного застою та інших хронічних венозних захворювань. Основним принципом цього лікування є застосування певного тиску на тканини, що оточують уражену ділянку. Залежно від величини прикладеного тиску компресійний одяг може впливати на внутрішній об’єм вен, артерій та лімфатичних судин. Таким чином, важливим завданням є визначення тиску, який створює компресійний одяг на тіло.

The elasticity of a knitted fabric is enhanced by the incorporation of elastane thread or core-spun yarn into the knitted structure as the weft yarn that is laid in the stretching direction. The quality of elasticized knitted fabrics is determined by the reliability of the how the elastomeric yarn is fixed within as the structure is deformed with an increase in the contact areas between the elastomeric and conventional yarns. The high fixing level can be achieved by the nature of loops formed from the elastomeric yarn. The simultaneous union of both conditions is possible with miss-knitting of elastomeric yarn through a certain number of needles. The main purpose of this study is to establish the influence of miss knit repeat of elastomeric yarn on the structural parameters and determine the stretch properties...

It affects also extensibility, width and length of product and, therefore, a whole appearance of the item. The study of the influence of knitting technological parameters on the loop length of elastic warp knitted fabric for the rehabilitation and preventional goods manufacture is the purpose of this research. The three-factor experiment has been planned and carried out during this study. The linear density of the weft filling-in yarn, the pre-elongation of an elastomeric thread and the tension of ground yarn were chosen as input factors. The regression equations that adequately describe the dependencies of the loop length on these technological parameters have been established.Dužina petlje je osnovni parametar pletene strukture, koja utiče na gustinu tkanine i njenu osnovnu težinu, kao i propus...
