As a kind of environment-friendly fiber, akund will create considerable interest in the apparel industry due to its fine luster, good moisture absorption, renewable and pollution free feature. This research is a comparative study of the physical properties of akund/cotton material and pure cotton material. Results show that the enhanced structure of akund/cotton compact yarn typically results in a lower hairiness and improved mechanical properties. However, the weaving of this kind akund/cotton blended yarn may meet a lot difficulty since its tenacity value hardly meet the minimum value calls for weaving. Another important guidance is that it necessary to reduce short fiber content that may be present in the yarn structure to adopt best evenness.

The functionality of textiles can be complimented by using a wide variety of modification technologies. This study focuses on textile modification with sol-gel technology as a part of smart sock prototype development. Zinc acetate dehydrate (ZAD) is integrated in sol synthesis and used as modifier thus improving modified cotton yarn mechanical properties and also can prolong time between washing, taking into account modifiers antimicrobial properties. Four hanks of pure cotton yarns with length of 300 m, where modified with silica-based sol with 7,5 wt% ZAD as a modifier. As a part of this study tensile strength and elongation of yarn was determined and changes in liner density were observed. Average yarn linear density increases by 19 % and linear density for knitted samples increases by 2,6 %. Therefore, yarn strength for 80 % of modified samples shows mean value of 2,32 N, that is 17 % higher than unmodified samples.

And Performance

Denim is one of the most popular casual apparel all over the globe due to a variety of available looks, comfort, and convenience. Comfort and performance properties of stretched denim fabrics depend on the elastane content, which can be controlled through the linear density of elastane and draft-ratio in the core of the cotton yarn. Optimization of both of linear density and draft-ratio of elastane for the better performance of denim fabric were focused upon in this study. The results indicated that the elastane content inside the core of yarn affects the dimensional and mechanical properties of denim fabrics. Regression analysis indicated that elastane linear-density and draft-ratio had an almost equal significance on contraction after washing, stretchability, stiffness, skewness, and bow of fabric. However, the elastic properties of fabric were mainly dependent on the elastane draft-ratio. This study will be an endeavor for industry personnel to achieve more durable and dimensionally stable denim fabrics.

This study was conducted to identify the factors and the interactions which affect the maximum load of multi-thread fancy yarns. The objectives of this research was to identify the relative contribution of each factor and interaction leading to the maximisation of the tensile strength. The fancy yarns were made on a hollow-spindle spinning machine. The experimental design of this study had seven factors – with two levels each and was repeated five times. It was found that using two single yarns, instead of a similar two-ply yarn, for the core component increased the value of maximum load. The effect component contributed positively to the load only when it was a three-ply cotton yarn rather than a three-ply bamboo yarn since the former had interactions with the core and the binder. Excessive wraps reduced the maximum load. The effect of the overfeed ratio on the maximum load was weak. The manufacturing process in general had low levels of variability. This research is important because it contributes to a broader understanding to the effect of seven factors on the structure, quality, and mechanical properties of multi-thread fancy yarn.

Abstract A very promising cellulose-based natural fibre that is suitable for use in the textile industry is peat fibre. This fibre is a by-product of peat excavation, purified by separating it from other components. In this study, the morphological, chemical and mechanical properties of peat fibres as well as flammability of peat-based knitted fabrics were analysed. The average diameter of the peat fibres is ~60 μm, but it varies in very wide ranges – 25–150 μm; however, the number of fibres with diameter more than 100 μm is very low. As the peat fibre contains a high amount of lignin, lignin amount in the mixed peat/cotton yarn is relatively high too. Lignin is responsible for enhanced flame retardancy; therefore, time to ignition of the peat knit is ~30% higher than that of the cotton knit. Consequently, peat fibre can be used in the knitted structure in order to significantly reduce its flammability. In order to increase the flame retardancy, the knits have been treated by flame retardant in various concentrations. It was found that around the burned hole on the peat knit, treated by very low concentration flame retardant, forms charred area and the knit stops to burn even if the flame source is not removed.

This paper studied the mechanical behavior of the filament/staple fiber composite yarn and the pure cotton yarn under the isostress and isostrain of cycling tensile strength with the conditions of small deformation. And it also analyzed the elastic recovery rate, creep rate and stress relaxation rate under the different deformation rate and load. The results show that the mechanical properties of elastic recovery rate, stress relaxation and creep all keep in good range in the experiment of cycling tensile strength with low certain elongation and constant load; as the increase of certain elongation and constant load, the mechanical properties of elastic recovery rate, stress relaxation and creep have much difference, just in terms of the conformality under the cyclic tensile strength, PET/PU/cotton composite yarn shows the best, next is the PU/cotton composite yarn, and then next is the PET /cotton composite yarn, and the pure cotton yarn shows the worst.

Cotton fiber is a type of natural fibers. Using natural fibers to fabricate textile can not only decrease the consumption of synthetic fibers, but also reduce the environmental pollution. This study aims to fabricate elastic knitted fabrics and evaluate their properties. Polyester (PET) filaments and rubber threads serve as the warp while cotton yarn serves as the weft for warp knitting. A crochet machine makes the warp and weft into warp knits with desirable stretchability, during which the amount (single/double) and the ply number (1-, 2-, and 3-ply) of the weft are further varied. The resulting warp knits are evaluated for water absorption, air permeability, and mechanical properties. As demonstrated by the experimental results, the warp knits with single 1-ply weft (S1) yield an optimal air permeability of 224.6 cm3/cm2/s and stiffness along the warp direction of 4.74cm. The warp knits with single 2-ply weft (S2) display an optimal tearing strength of 86N while the warp knits with double 3-ply weft (D3/3) has an optimal tensile strength of 708N.

In compact spinning, fibers in drawing stage are condensed using air suction, which results in the produced yarns which significantly differ from ring spun yarns in their physical and mechanical properties. This study compares between physical properties of compact and ring yarn fabrics woven from coarser and medium yarn counts. The experimental results were statistically analyzed using ANOVA. The findings of this study revealed that woven fabrics produced from compact spun yarns are superior to those produced from ring spun yarns with respect to breaking strength, breaking elongation, abrasion resistance, tearing strength, and air permeability.
