Modern quality management systems

The quality of the product depends upon the process and systems deployed. In this chapter all quality systems in practice are covered for understanding and comparison. You will also learn product quality and test methods for the terry towel protocols of some of the retailers.

Absorbency and serviceability of terry fabrics

There are a number of variables that affect the properties and performance of woven terry fabrics. The interaction of these variables is also an important aspect that needs to be considered for the optimisation of fabric behaviour. Water absorbency, compression and hand are the important properties of woven terry fabric that govern its quality, performance and serviceability. Various factors affecting the water absorbency and serviceability of woven terry fabric are described in the present chapter.

Producing high-quality terry fabrics

There are a number of variables that affect the properties and performance of woven terry fabrics. The interaction effects of these variables are also an important aspect that needs to be considered for the optimisation of fabric behaviour. Water absorbency and compression are the important properties of woven terry fabric that govern quality and performance. Box and Behnken designed an experiment that is an important tool for the optimisation purpose. The production of high-quality woven terry fabric by optimising the different fabric parameters is described in this chapter.

Winding yarn for terry fabrics

The winding process makes the yarn run continuously in the next process thus increasing efficiency and product quality. Various process sequences utilised for producing different types of yarn have been discussed here. The different machines used in the winding process have also been described, along with their important parts, such as tensioners and slub catchers. Process control of the winding is also discussed, along with a description of various faults.

Overview of terry fabrics, properties, application and care

The quest behind the evolution of the terry fabric along with its special characteristics has been discussed in this chapter. The current form of terry fabrics has been achieved through a continuous development process. Its application is not limited to absorbing water but has gone far away towards the world of luxury and care and become an integrated part of our life.

Properties and performance of woven terry fabrics

The properties and performance of woven terry fabrics depend upon the fibre and yarn properties. The mechanism of fibre and yarn bending plays an important role in the compression and hand behaviour of terry fabrics. The measurement of the textural and serviceability behaviour of the terry fabric has been described in this chapter. Various research work done related to the properties and performance of terry fabrics has also been discussed.

Weaving of terry fabrics

The production of high-quality woven terry fabric is a complex process, part of which is performed on an especially designed and equipped loom. The mechanism of the loom that is responsible for the production of the pile loop on the fabric surface is known as the terry mechanism. Since the inception of terry fabric production, a number of mechanisms have been invented. A number of possible terry fabric structures have been produced. With the advancement in the technology of electronics, microprocessor-controlled, highly dynamic stepping motors, with modern mechanisms have helped technologists to produce elaborate and beautiful patters on the terry fabric during weaving. These technical and structural developments are described in this chapter.

Warping for terry fabrics

The production of high-quality woven terry fabric is a complex process and is mostly dependent on a high-quality preparatory process. Warping is an important preparatory process that needs precise control. An understanding of the process kinematics helps the manufacturer to preserve and maintain the yarn elongation and strength up to required level which helps in the production of good-quality beam. Constant yarn tension and the continuous machine operation without stoppage is the key to success in the warping section.

Hand evaluation of woven terry fabric

The hand of woven terry fabric gained its importance due to the todays demand for quality. It was felt that subjective hand evaluations could not fulfil our purpose, therefore, an objective evaluation of terry fabric hand has been devised. This has led to the development of special hand equations for the woven terry fabric. The process of development of primary and total hand equations has been described in this chapter. A new surface sensor—KES-FB4—has also been developed. The experimental verification of the results has also been described in the current chapter.

Compression and surface characteristics of terry fabrics

The compression and surface characteristics of terry fabric play a crucial role in determining its hand and aesthetic behaviour. The number of variables related to fibre, yarn and fabric governs these characteristics. The effect of different fibres, yarns and fabric variables on the compression and surface characteristics have been described in this chapter.
