Abstract

Purpose

Fabric structural parameters play an important role on the thermal comfort of clothing. The purpose of this paper is to investigate the effect of weave pattern and also the length of warp float in each weave pattern on the thermal properties of woven fabrics.

Design/methodology/approach

Cotton woven fabrics with 23 different weave patterns were produced with identical linear densities of warp and weft yarns as well as constant warp and weft nominal densities. Thereafter, their thermal properties were studied.

Findings

Statistical analysis demonstrated that the weave pattern significantly influences on the thermal properties of woven fabrics. Plain fabric exhibited the lowest thermal resistance and the highest thermal conductivity, and hopsack 2/2(4) weave fabric demonstrated the highest thermal resistance and the lowest thermal conductivity. Moreover, except hopsack (4) weave fabric, in all weave patterns, the length of warp float had a significant effect on the thermal characteristics of the fabrics, as increasing the warp float led to increase in the thermal resistance of the fabrics.

Originality/value

Weave pattern as one of the structural parameters of the fabric has a determinant role on the thermal properties of fabric and subsequently, the comfort of clothing produced from it. Owing to the lack of investigation in this area, this research considers the effect of weave pattern and the length of warp float in each weave pattern on the thermal properties of woven fabrics.

Abstract

Purpose

The purpose of this paper is to analyse the advantages of a new interpretation of the geometric disposition of threads within woven fabric structures, and to develop a method of determining the parameters of threads, with reference to each order of their disposition.

Design/methodology/approach

Based on the analysis of the geometrical models proposed by Barker and Midgely, by Pierce and by Novikov, the substantiation of the advantages of a stricter model, offered by the authors, for determining the geometric disposition of threads within single layer woven fabric structures with the help of the tangent function is given. This model allows the substantial expansion of the actual bounds of the interval of the order of the geometric disposition of threads in woven fabric structures to 0.2‐9.8.

Findings

The tangent function can approximate the crimp height ratio of the warp threads within the woven fabric structure with accuracy within the limits of geometric disposition angle change from 1° to 89°.

Research limitations/implications

The work has applications in the industrial production of woven fabrics.

Practical implications

This research will allow the design of a woven fabric with practically any ratio of crimp height for the warp and weft threads to effectively achieve the required performance characteristics of the cloth.

Originality/value

This paper extends the knowledge of the geometrical characteristics of woven fabric structure, and proposes intelligent methods of determining the parameters of thread cross‐sections in accordance with the orders of the geometric disposition of threads in woven fabric structure.

Abstract

Purpose

The purpose of this paper is to investigate the relationship between the formability of cotton and cotton/polyester woven fabrics and their selected properties: weft density, weave and a way of finishing. It shows how the mentioned properties influence fabric formability and analyze a statistical significance of investigated relationships.

Design/methodology/approach

In paper two groups of cotton and cotton/polyester woven fabrics of different structure and a way of finishing have been measured in the range of their basic structural properties as well as bending rigidity and initial Young’s modulus. Formability of investigated fabrics has been calculated on the basis of bending rigidity and initial Young’s modulus. Next, ANOVA has been performed in order to analyze the relationships between the weft density, weave and a way of finishing of woven fabrics and their formability.

Findings

The paper shows that all selected properties of woven fabrics significantly influence their formability as well as that there is statistically significant interaction between mentioned independent factors. It provides empirical results confirming that the influence of raw material composition of investigated cotton and cotton/polyester woven fabrics on the formability of fabrics is statistically insignificant.

Research limitations/implications

Results of investigations can be applied for cotton and cotton-like woven fabrics.

Practical implications

The paper includes implications for woven fabric engineering from the point of view of achieving the expected fabric formability.

Social implications

The results enables the choice of appropriate fabric for the given clothing.

Originality/value

This paper fulfills an identified need to study how the formability of woven fabrics can be shaped by an appropriate selection of their structure and a way of finishing.

Abstract

This experimental work demonstrates the effect of weave structure on the skewness of fabric. The work shows that the distortion of gray woven fabrics depends upon the behaviour of the floats (which is related to the factor of weave) at the state of relaxation. Nine, 50-metre rolls of woven fabrics in different weaves were produced. The fabrics were marked in a rectangular form (1.70 metres in width and one metre in length) at the weaving machine. After 24 hours of relaxation, the new shapes and sizes were recorded. The deformations of the fabrics due to the weave structures were different. The shapes of almost all of the samples were changed to Trapezium, even though they differed in size. This experimental work showed that, of the nine different weaves, the 3/3 twill weave had the highest skewness and the Zigzag twill structures the lowest, proving that the type of weave affects the deformation and, as a result, the skewness of the fabric.

Abstract

Purpose

Testing the effect of machine washing and drying on dimensional stability produces information about the fabric types that satisfy consumers during end use. At present, it is a known fact that the weave patterns affect the dimensional stability property of woven fabrics. But the essential requirement is to determine the magnitude of this effect for weave types and establish the proper weave types for end use in definite tolerances. The purpose of this paper is to investigate the dimensional stability properties of 100 percent cotton woven fabrics as a function of weave type.

Design/methodology/approach

In total, 12 woven fabrics with different weave derivatives are woven with 100 percent cotton and Ne 30/1 combed ring spun yarn for this investigation. These samples are then washed and dried according to domestic washing and drying standard test procedures. The shrinkage values are measured and then expressed as a percentage of the initial dimensions.

Findings

It was observed that weave pattern has a significant effect on the dimensional behavior of woven fabrics. Weave patterns with a high number of interlacings have lower shrinkage values. At the same time, lower yarn crimp values restricted the fabric shrinkage and resulted in better dimensional stability. According to one way ANOVA results, the effect of weave type on dimensional stability is found to be significant (p<0.01). In addition to these, Pearson correlation analysis showed that there is an important, positive and fair relationship between the number of washing cycles and total shrinkage.

Research limitations/implications

The study covers 100 percent cotton woven fabrics with one type of warp and weft sett. The only finishing treatment applied to the sample fabrics was desizing. No dyeing was carried out.

Originality/value

Understanding the magnitude of the effect of weave type on dimensional stability of cotton woven fabrics produces more knowledge about products which satisfy the customers with respect to dimensional stability during usage.

Abstract

Purpose

Development of a technique for weaving seamless three‐dimensional shapes directly on loom is an essential step in producing seamless woven garments. The purpose of this paper is to report a new approach to weaving seamless three‐dimensional shapes.

Design/methodology/approach

Spacing of warp and weft threads varies in shape region. Reeds with shaped reed wires are developed to change spacing of warp threads. Interlacement pattern of warp and weft threads is selected that assists in changing spacing of threads. The new approach of weaving three‐dimensional shapes in folded form is developed, that offers advantages over weaving shape in erect form.

Findings

The main findings were mathematical determination of shapes of reed wires to produce a three‐dimensional woven shape and weaving shape in folded form.

Originality/value

The paper demonstrates how three‐dimensional shapes are woven in folded form without the need of eliminating ends.

Abstract

Purpose

The purpose of this paper is to develop a computerized program that can recognize woven fabric structures and simultaneously use the obtained data to 3D re‐visualize the corresponding woven fabric structures.

Design/methodology/approach

A 2D bitmap image of woven fabric was initially acquired using an ordinary desktop flatbed scanner. Through several image‐processing and analysis techniques as well as recognition algorithms, the weave pattern was then identified and stored in a digital format. The weave pattern data were then used to construct warp and weft yarn paths based on Peirce's geometrical model.

Findings

By combining relevant weave parameters, including yarn sizes, warp and weft densities, yarn colours as well as cross‐sectional shapes, a 3D image of yarns assembled together as a woven fabric structure is produced and shown on a screen through the virtual reality modelling language browser.

Originality/value

Woven fabric structures can now be recognised and simultaneously use the obtained data to 3D re‐visualize the corresponding woven fabric structures.

Abstract

The Igbos are renowned for their success in business. This chapter traced the pre-colonial and post-colonial innovations among the Igbos to highlight salient factors that could be responsible for their outstanding success in recent times. In the pre-colonial era, the Igbos made their livelihood through vocations such as blacksmithing, traditional medicine, farming, pot moulding, hunting, food preservation, and textiles, especially in cloth weaving. The post-colonial period which witnessed the Nigerian civil war, led to a disruption of their entire business structure. However, through the principles of apprenticeship and hard work, ingredients of success in the pre-colonial years, the Igbos were able to rebuild their business structure and became renowned for their success. They retained some of their pre-colonial crafts such as cloth weaving of which the Akwete fabric is a good example and has gained both national and international prominence in recent times. The chapter presented the case of the Akwete Weaving Centre of Alex Ekwueme Federal University Ndufu-Alike Ikwo (AE-FUNAI), established to promote cultural heritage and enhance the entrepreneurial skills of students in the craft through modern apprenticeship. The chapter made recommendations on ways to enhance the Akwete Weaving industry and effectively harness its potentials.
