Abstract
Purpose
The purpose of this paper is to discuss the use of stereoscopic virtual technology in textile and fashion studies in particular to the area of chemical experiment. The development of a designed virtual platform, called Stereoscopic Chemical Laboratory (SCL), is introduced.
Design/methodology/approach
To implement the suggested educational approaches of SCL, a set of teaching and learning materials with emphasis on the application methods was revised from the existing subjects. The architecture of SCL includes building of virtual objects with the Autodesk software Maya and designing of interactivity by using Unity, a game engine system. Prototype version of the SCL has been passed to selected academic colleagues and students for further evaluation and application feedback.
Findings
Textile students can conduct laboratory experiments associated with coloration and finishing of textile technologies in a stereoscopic 3D and multisensory laboratory, and hence enhance their learning experience. With the use of SCL, students can learn relevant experiment tools, experimental processes, procedures, and safety and health precautions.
Originality/value
There is very limited educational or training approach in applying stereoscopic virtual reality in teaching activities. In the area of textile experiment, the authors could say it is virtual and does not exist in current research domains.

Abstract
Purpose
This paper aims to prepare an associative thickener base on two polyacrylate-based copolymers, which can be used for digital printing of nylon carpet with enhanced performance.
Design/methodology/approach
An associative thickener was prepared by compounding two polyacrylate-based copolymers, cationic starch and polyacrylic acid; and mediated by polyethylene glycol and polyacrylamide crosslinker. The formulation of the associative thickener was optimized by using the orthogonal array testing strategy. The stability of the associative thickener was investigated by measuring effects of temperature, electrolytes, storage time and auxiliaries on viscosity. The associative thickener was compared with a commercial thickener by evaluating their performance in digital printing of nylon carpet.
Findings
The associative thickener provided same color strength and fastness in the printing of nylon carpet as the commercial one, but was more easily washed off for a better hand feeling of the printed carpet.
Practical implications
The prepared associative thickener can be applied for digital printing of nylon carpet.
Originality/value
The associative thickener can be facilely prepared from commercially available chemicals and suitable for digital printing of nylon carpet.

Abstract
This research focuses on the effects of paste pre-treatment, concentration of sodium alginate, steaming conditions for colour yield and outline sharpness of ink-jet printing. The results show that (a) coating is a better method than padding for paste pre-treatment of cotton fabrics; (b) 102°C × 12min is the best condition for steaming; (c) pattern sharpness is better when the concentration of sodium alginate increases; and (d) color yield diminishes when the concentration exceeds 20g/L. In other words, when the optimum concentration of sodium alginate is 20g/L, the amount of ejected ink can reach as much as 260%. In this study, four reactive dyes (i.e. cyan, magenta, yellow and black) of different chemical constitutions were used, and the colour fastness results against washing and light reveal an acceptable rating above grade 4.

Abstract
In this study, the foam dyeing technology was applied to dye cotton knitted fabric for achieving the surface-dyed result. The T-shirt made by this surface-dyed fabric could easily obtain the wash-out effect after garment laundering. The pigment dyeing performances in foam dyeing were system studied. Colour strength, colourfastness and serviceability of fabrics dyed with the methods of foam-padding and liquid-padding were evaluated and compared. Results show that surface dyeing for cotton-knitted fabric with foam media could overcome the shortcoming of poor penetration in foam dyeing method, and turn the poor penetration into the superiority for obtaining the surface-dyed result. The serviceability such as water absorption and handle property was also well improved in foam dyeing method. Finally, the advantages of energy saving and reducing chemical usage were implemented throughout the dyeing process.

Abstract
Wool fabrics were treated with plasma under the influence of different plasma gases were assessed by Scanning Electron Microscopy (SEM), X-ray Photoelectron Spectroscopy (XPS) and Fourier Transform Infrared Spectroscopy with Attenuated Total Internal Reflectance mode analysis (FTIR-ATR). Experimental results showed clearly that the surface feature and chemical compositions of LTP treated wool were varied much dependable on the nature of plasma gas used and the variations were finally discussed.

Abstract
Textiles are a suitable substrate for the growth of micro-organisms, especially at appropriate humidities and temperatures, when in contact with the human body. Due to the awareness that healthcare textiles enhance the quality of life, antimicrobials and antibacterial textiles have received, and continue to receive, considerable attention from researchers due to their potential to provide quality and safety benefits to many products. However, antimicrobial agents and antibacterial finishing processes have not grown in number because of possible harmful or toxic effects on humans and the environment. The application of rechargeable, safe antimicrobial agents and eco-friendly antibacterial finishing processes are being studied. This paper analyzes the disadvantages and advantages of antimicrobials and antibacterial finishing processes and finds suitable antimicrobials and antibacterial finishing processes for cotton. It is anticipated that the review will be a good resource for those who are interested in antimicrobials and biocidal textile materials, and will help to stimulate further interest in this area.

Abstract
This paper is a study of the current trends and conditions of electronic resources for Chinese studies, based on a recent survey on the Internet of 29 Chinese libraries in North America and eight Chinese libraries in China, Taiwan and Hong Kong. The survey discussed current electronic resources for Chinese studies, with a union list of major Chinese language databases currently used in libraries in Asia and the US. Current views on the use and development of electronic resources for Chinese studies were summarised.

Suggests that misunderstandings frequently occur when trying to understand Chinese language and culture, and so gives the implied meaning of various Chinese expressions and sayings such as greetings, thanks, respect, age, congratulations and taboo subjects.

Abstract
Purpose
This paper was motivated by the absence of a government examination of and professional interest in planning conditions as a means of development control in Hong Kong. Proposes to examine this situation.
Design/methodology/approach
The research objective is achieved by a field survey and legal analysis of its findings. The field survey of all the 60 residential development projects in Hong Kong under comprehensive development area zoning subject to conditional planning permissions from 1998 to 2000 involving 119 planning applications was conducted to assess factual compliance with planning conditions.
Findings
The findings show that, while most physical planning obligations have been duly fulfilled in these projects, the non‐depositing of master layout plans for development poses actual and potential public domain problems of planning enforcement, building permission, conveyancing and property management. The major problems of non‐compliance are property purchasers being unable to fully appreciate the environment of a development when making a decision to buy; subsequent titles defects, unauthorised building works and operations. Suggestions are made to close the loopholes in planning law and to introduce a formal channel for retrospective rectification in the light of the social consequences of non‐compliance.
Originality/value
This paper is the first serious attempt to evaluate the importance of compliance with planning conditions in Hong Kong and its analysis should be of interest not only to local policy makers and professional people in particular, but also to researchers in comparative development control in general.
