This study aims to develop a four-dimensional (4D) textile composite that self-forms upon thermal stimulation while eliminating thermomechanical programming steps by using fused deposition modeling (FDM) 3D printing technology, and tries to refine the product development path for this composite.

Polylactic acid (PLA) printing filaments were deposited on prestretched Lycra-knitted fabric using desktop-level FDM 3D printing technology to construct a three-layer structure of thermally responsive 4D textiles. Subsequently, the effects of different PLA thicknesses and Lycra knit fabric relative elongation on the permanent shape of thermally responsive 4D textiles were studied. Finally, a simulation program was written, and a case in this study demonstrates the usage of thermally responsive 4D textiles and the simulation program to design a wrist support product.

The constructed three-layer structure of PLA and Lycra knitted fabric can self-form under thermal stimulation. The material can also achieve reversible transformation between a permanent shape and multiple temporary shapes. Thinner PLA deposition and higher relative elongation of the Lycra-knitted fabric result in the greater curvature of the permanent shape of the thermally responsive 4D textile. The simulation program accurately predicted the permanent form of multiple basic shapes.

The proposed method enables 4D textiles to directly self-form upon thermal, which helps to improve the manufacturing efficiency of 4D textiles. The thermal responsiveness of the composite also contributes to building an intelligent human–material–environment interaction system.

The purpose of this paper is to investigate effect of material properties in 3D knitted fabrics on thermo-physiological comfort.

In the present study six different spacer fabrics were developed. Among these six fabrics, it was classified into two groups for convenient analysis of results, the first group has been developed using polyester/polypropylene blend with three different proportion and second group with polyester/polypropylene/lycra blend having another three different composition. As a spacer yarn, three different types of 88 dtex polyester monofilament yarn and polyester multifilament yarns (167 dtex and 14.5 tex) were used and 14.5 tex polypropylene and 44 dtex lycra multifilament yarns were also used for the face and back side of the spacer fabrics (Table I). These fabrics were developed in Syntax Pvt Ltd Czech Republic.

The main influence on the water vapour permeability of warp knitted spacer fabrics is the kind of raw material, i.e. fibre wetting and wicking. Also there is no correlation between air permeability and water vapour permeability. It is found that both air permeability and thermal conductivity are closely related to the fabric density. It is also found that the fabric characteristics of spacer fabric show a very significant effect on the air permeability, thermal conductivity and mechanical properties of spacer fabric. Therefore, selection of spacer fabric for winter clothing according to its fabric characteristics.

The main objective of the present study is to produce spacer knitted 3D fabrics suitable for defined climatic conditions to be used as clothing or in sports goods.

New 3D knitted spacer fabrics can be produced with improved comfort properties.

The purpose of this paper is to investigate microwave reflection, transmission, and complex permittivity of p‐toluene‐2‐sulfonic acid doped conducting polypyrrole coated nylon‐lycra textiles in the 1‐18 GHz frequency with a view to potential applications in the interaction of electromagnetic radiation with such coated fabrics.

The chemical polymerization of pyrrole is achieved by an oxidant, ferric chloride and doped with p‐toluene sulfonic acid (pTSA) to enhance the conductivity and improve stability. Permittivity of the conducting textile substrates is performed using a free space transmission method accompanied by a mathematical diffraction reduction method.

The real part of permittivity increases with polymerization time and dopant concentration, reaching a plateau at certain dopant concentration and polymerization time. The imaginary part of permittivity shows a frequency dependent change throughout the test range. All the samples have higher values of absorption than reflection. The total electromagnetic shielding effectiveness exceeds 80 percent for the highly pTSA doped samples coated for 3 h.

A non‐contact, non‐destructive free space method thin flexible specimens to be tested with high accuracy across large frequency range. The non‐destructive nature of the experiments enables investigation of the stability of the microwave transmission, reflection, absorption and complex permittivity values. Moreover, mathematical removal of the diffraction enables higher accuracy.

Effective use of capital is an important strategic tool for any manufacturing company operating in today’s high technology and capital intensive environment. This purpose of this paper is to carry out an investigative study into strategic business processes for capital effectiveness practices (CEP) in industry, by means of a literature review, a survey of a sample of UK and US companies and a case study of the Chemco Corporation.

This case study investigates the consumer perception of Tactel that has resulted from Invista's marketing strategy of generating brand recognition for Tactel and considers whether the consumer understanding of the product and its benefits correlate to the intentions of Invista.

Interviews, questionnaire and consumer garment comparisons test.

It was found from interviews conducted with representatives of companies involved in a UK based supply chain producing Tactel lingerie during both the Autumn/Winter (A/W) 2000‐2001 and A/W 2003‐2004 seasons that all representatives agreed that consumers do not understand the meaning of Tactel and do not really understand its benefits. The results from the consumer questionnaire confirm this view as consumers were not able to identify key words associated with Tactel effectively. It was found from the consumer garment comparisons test, however, that although consumers may not be sure about the particular attributes of Tactel and its benefits awareness of the brand has increased following a very focused brand promotion since A/W 2000‐2001. Whilst Tactel may not mean anything to consumers, it is now becoming an integral part of consumers' vocabulary in the A/W 2003‐2004 season as Invista had intended.

A useful insight into consumer recognition of a fibre brand.

Pressure garments are mainly made of elastic Lycra fabrics and tailor‐made to individual patients’ measurements to provide an appropriate amount of skin‐garment interface pressure for burn rehabilitation. However, the fabric tension would be different at various locations from the hem edges of pressure garments, and thus the skin‐garment interface pressure cannot be uniformly maintained over the interface surface. Aims to investigate the pattern of interface pressure changes caused by the different types of edge finish used for making pressure garments. The effect of garment sizes on the change of interface pressure was also examined. Experiments were carried out using two selected elastic Lycra fabrics, four types of hem finish and three different garment sizes. The results of the study provide a guideline for designing the edge finish of pressure garments, and a minimum margin from the hem edges of garments to the scar area is also recommended.

The purpose of this research is to investigate knowledge management in the textile industry specifically through the relationships and interconnections of knowledge management systems, strategy and firm performance across the value chain.

This research examines the process of acquisition, retention, maintenance, and retrieval of knowledge both within the firm through organizational memory and across the value chain. A series of case studies examines how Invista (a Du Pont subsidiary) manages knowledge internally and externally through relationships with downstream partners across a single value‐chain within the textile industry. Qualitative interviews assess the “state of the industry” regarding knowledge management systems.

Differentiation through knowledge is difficult in practice. Invista has taken the first steps to develop knowledge management systems that connect the internal and external knowledge base to gain competitive advantage. Establishing internal knowledge management systems for organizational memory creates opportunities to minimize knowledge isolation in functional departments and creates a greater base for tacit learning to be leveraged. External knowledge management systems bring value chain members closer together and add value to the product (i.e. increased quality, customer perceptions of brand platforms) throughout the value chain. Active external knowledge systems create opportunities to reap the full benefits of internal knowledge and knowledge from other firms within the network.

This paper describes the process of acquisition, retention, maintenance, and retrieval of knowledge within the firm by improving organizational memory and across the value chain through knowledge management systems to gain competitive advantage.

Elastane yarns contribute significant elastic properties to all types of fabrics and these properties for very important for wears including tights, sportswear, under wear, casual wear, swimwear, corsetry, etc. in terms of appearance, comfort and duration of wear. The paper aims to discuss this issue.

It is investigated with this study strength, fatigue and bagging properties of plated plain knitted fabrics containing different rates of elastane.

The study showed that single jersey, not having elastane and having the lowest fabric tightness, has the lowest bursting strength, the highest fatigue loading values in high extensions, the lowest fatigue height values and the worst bagging behavior. On the contrary of single jersey, full elastane fabric has the exact opposite characteristics considering the fabric properties examined.

Fabric with 1×1 elastane and fabric with 2×1 elastane is similar, and these fabrics show bagging behavior better than single jersey and worse than full elastane fabric whereas the other properties of these fabrics are close to full elastane fabric.

This study aims to show that the manner of fabric deformation during relaxation depends upon the twill angle line and its direction (twill S or Z). The quantity of the skewness is related to the float length and the twill angle in reverse, with the warp tension when changed from cotton to lycra filling yarns.

The experimental analytical method.

The most significant goals presented from this investigation are cost savings, time of production and metaphorically; new demands on denim fabric patterns presented.

Moving away from just chasing cheap, more innovative and progressive for manufacturing and end users search for denim, this paper served to shift the market share map for denim manufacturers, which is looks on nearly the most common problem facing the denim industry; skewness.
