Influence of Weave Parameters on Woven Fabric Tear Strength

The influence of weave on woven fabric tear strength is analysed in this paper. Brierlay’s factor Fm, Milašius’ factor P and P’ and modification of parameter P made by the authors (P’weft) were used in the investigations presented. Woven fabrics of 100 % viscose multifilament yarn manufactured from the same yarns and with the same density but with seven different weaves (plain weave, weft rib 2/2, warp rib 2/2, twill 2/2, twill 3/1, basket weave 2/2 and 4 healds sateen) were used for the investigations. It was stated that the well-known weave parameters of Brierley Fm and Milašius P and P’ cannot be used for the prediction of the tear strength of all kinds of weaves without any limitations. All parameters presented can be used for the strength prediction of a weave when they are divided into two groups – a rib-based group and twill-based group. Prediction of the tear strength for rib-based weaves in the weft has to be carried out using parameter P’weft, where the influence of parameters P1 and P is varied.

Influence of weave and densities on visual appearance of woven fabrics made from two colored yarns

The paper examines the effect of different factors, i.e. weft density, weave type and consequently agglomeration of the interlacing points of the same type, on the colour impression of a woven fabric. The experimental part is based on 60 weaved samples which differ in weave type (we used 10 different weave types in which the technical face and technical back are the same), colour of the warp (we used white and black warp) and weft density (we used yarns with densities 15, 20 and 25 yarns / cm). We measured the colour values of the woven samples. We arranged the measurements in different ways and tried to visually evaluate the effect of density, effect of weave type, also the effect of the size and shape of agglomerated interlacing points of the same type, on the colour impression of the woven fabric. The results of the colour measurements were sorted into tables and presented in graphs, which were used to find the samples within the observed groups of characteristics that showed the biggest colour differences, to calculate these colour differences and observe and explain the effect of the observed factors on the colour impression.

Effect of processing and wearing on viscoelastic modeling of polylactide/wool and polyester/wool woven fabrics subjected to bursting

Polyester fibers (PET) are greatly used in textiles but depend on fossil fuel resources. Poly-(lactic acid) (PLA) is an aliphatic polyester that can be derived from 100% renewable resources. The load–extension plot of a polylactide fiber seems to be especially compatible with that of wool. Consequently polyester/wool 55/45 and polylactide/wool 55/45 yarns were spun using the Sirospun process and plain and twill woven fabrics were industrially produced. Washed and heat set fabrics were subjected to a conventional process of dyeing and decatizing. Fabrics were gradually worn by abrasion using a Martindale wear and abrasion tester. Using the bursting strength test, the viscoelastic behavior of the fabrics when multidirectional extended was simulated and modeled using a modified non-linear Maxwell model. The three steps of fiber decrimping and orientation, fiber stretching and maximum yield and breaking were analyzed. PET/wool fabrics show a more linear behavior than PLA/wool ones and the influence of weave, finishing and wearing on the viscoelastic behavior of PLA/wool fabrics were highly relevant when compared with that on PET/wool ones. It seems that when blended with PET, wool develops its felting effect during finishing and wearing, while when blended with PLA, the felting effect of wool is hardly developed due to the lower resistance of PLA to hydrolysis and its lower thermal stability. PLA fiber properties need to be improved probably through the development of new L-D lactide (PLDLA) copolymers of different ratios between components and molecular weights to reach the optimal desirable properties for the fiber.

Influence of weave of carbon fabric on abrasive wear performance of polyetherimide composites

Three composites of Polyetherimide (PEI) reinforced with carbon fabric (CF) of three weaves viz. plain, twill and satin-4 H were developed keeping the amount of fabric constant (55% by vol.). Studies on mechanical properties confirmed that the twill weave composite (T) showed the highest strength, modulus (both tensile and flexural) and interlaminar shear strength (ILSS) followed by satin (S) and plain weave (P) composites. The performance order, however, was reverse in the case of toughness and elongation to break. Specific wear rate in a single-pass, unidirectional and un-lubricated abrasive wear mode against SiC paper showed strong influence of weave in mild wear condition (load 10 N). Composite S showed the highest wear resistance (W R) followed by composites T and P. With increase in load, the difference in performance diminished to the extent that at 40 N, it was almost similar for all the three composites. This was correlated with the difference in the length of the fibers between crossover points which, in turn, allowed the microdisplacement of fibers in the composites during abrasion. This was supported by the SEM.

Influence of Weave into Slippage of Yarns in Woven Fabric

Slippage resistance of yarns at a seam in woven fabrics is a very important factor and very strict claims are raised for this property. It is necessary to know how fabric structure influences on seam slippage quality before manufacturing the fabric. The purpose of this work was to establish which of the weave factor is most suitable to describe balanced weave fabrics seam slippage. It was investigated seam slippage characteristics in the fabric and the factor was offered, which characterizes best fabric structure from the thread slippage point of view. Fifteen wool fabrics, which differ only on weave were weaved for investigations. The test was carried out according to LST EN ISO 13936-1standard. First of all, the well known factors such as fabric structure factor P and average float F were investigated and then a new fabric structure factor was offered, which the best characterizes the weave from thread slippage point of view. The proposed model shows good correlation between experimental and theoretical values of the new weave factor.http://dx.doi.org/10.5755/j01.ms.17.1.248
