Abstract
The purpose of this study is to investigate an objective method of evaluating the tactile comfort of blankets by a method of connecting the mechanical parameters of blankets to subjective evaluation. The two methods are preliminarily investigated as follows: (1) Transformation equations for the fabric hand of suiting, KN‐101‐W for primary hand values and KN‐301‐W for THV, are applied, with the mean and standard deviation applied to these equations replaced with new values for the blanket population. (2) A new prediction equation is constructed for deriving THV directly from the mechanical parameters and thermal properties. The prediction accuracy of method (2) is a little higher than that of (1). The durability of blankets during repeated use and repeated dry cleaning determined by the initial performance of blankets is also investigated.

Abstract
Explains the origins of the development of the handle method, and lists the three criteria for predicting fabric quality. Shows how fabric handle evaluation is used, for example, handle analysis expresses characteristics and quality. Goes on to explain hand value and total hand value with the aid of equations and charts. Concludes that the textile technology must apply today’s technologies to the production of higher grade fabrics – i.e. ideal fabrics.

Abstract
This paper reports the recent progress in the ideal fabrics project that started in 1996. The aim of this project is to initiate the engineered manufacturing of “ideal fabric”. Ideal fabric is the fabric which satisfies the three conditions, good hand, good appearance of suit, and mechanical comfort for wear. The objective evaluation method of these three properties has been developed, and these objective method and fabric mechanics theories are fully applied to this project. Some ideal fabrics have been manufactured as the guideline for manufacturing ideal fabrics in the future. These trial fabrics are now being commercialized to assess the response of consumers.

Abstract
Engineered manufacturing of high quality garments has long been a target of textile technology. There are three main factors for manufacturing high quality garments. They are: the selection of good fabrics for the garments; the process control of garment manufacturing; and the performance and correct adjustment of manufacturing machines such as sewing machines. In recent years, objective evaluation technology of fabric quality has been developed, and many researchers are now moving toward the engineered design of fabric quality based on this objective evaluation technology. The present authors are also conducting research on these three factors on the basis of the development of objective evaluation technology. This paper consists of two parts. The first part is a brief introduction about the investigation of the first and the second factors, which have been investigated by the authors. The second part presents our recent research on seam pucker problems. This problem is a machine‐materials interaction problem, and the mechanical properties of sewing thread and fabric are closely connected in this problem.

Abstract
Presents a report on a recent experiment on the evaluation of seam pucker level by the objective method. Explains that human beings measure physical quantity and quality by means of subjective methods. Fabric hand evaluation is an example of this type of evaluation and an example of a relatively complex measurement with many relating physical variables. The measurement of seam pucker is a much simpler measurement than fabric hand evaluation, as only the fabric geometry along a seam line is visually observed and evaluated. This simplicity, however, is useful when investigating the human objective judgement of a geometrical phenomenon. Suggests that this investigation may be applied directly to the development of an objective system of seam pucker level.

Abstract
Discusses the 6th ITCRR, its breadth of textile and clothing research activity, plus the encouragement given to workers in this field and its related areas. States that, within the newer research areas under the microscope of the community involved, technical textiles focuses on new, ‘smart’ garments and the initiatives in this field in both the UK and the international community at large. Covers this subject at length.
