A Missed Opportunity to Learn from Failure

A dramatic improvement in yarn manufacture was adopted by the industry and went horribly wrong. Negative economic consequences were so great that improvements justifying the adoption of the technology have been ignored.

Comparison of Cleaning Treatments for Conservation and Restoration of Cotton, Wool and Silk Fabrics

Cleaning ensures sanitization and thus the safety of the artefact itself and others stored/displayed in its vicinity. At the same time, the process invariably alters the character of textile to a certain extent. Cleaning ensures removal/deactivation of soil and harmful organic matter from the artefact. However, a small number of surface molecules from the textile might be eroded in the process as well. This leads to weakening of the textile and might cause alteration in colour spectrum/ depth etc. Controlled cleaning techniques in conservation laboratories focus on minimizing this damage. However, not much scientific data is available on the efficacy of present cleaning techniques employed in conservation laboratories. Presently aqueous cleaning and solvent cleaning are primary modes utilised as next step to dry tools. Additionally, novel cleaning technologies like enzyme wash and ultrasonic wash provide soil specific methodology that would reduce the threat to the base fabric.

The present paper is a systematic analysis of these cleaning techniques and their impact on aged museum fabrics, i.e., cotton, wool and silk. Change in tensile strength parameters, whiteness index and yellowness index have been used as indicators to test the efficacy of different cleaning techniques on aged museum textiles. Numerical data generated by laboratory experiments clearly indicate that there is no standard cleaning treatment available for the three natural fibres. Each fibre has exhibited suitability to different cleaning treatment while balancing between restored whiteness and minimizing strength loss.

Nanotechnology Benefits in Fabric Formation

Nanometer (Nm) resins have been shown to modify fiber behavior in existing textile yarn. Incorporation of nanometer (Nm) resins in conventional warp size formulations improve weaving performance, improve fabric quality and reduce cost.

Environmental Aspects in Textile Industry: Ecological Hazards and Remedial Measures

Among many pollution-creating industries, textile has a larger share in terms of its impact with regard to noise, air, and effluent. It is, therefore, felt worthwhile to study the environmental hazards associated with various operations of textiles. In this paper, pollution arising out of noise and air is discussed. Areas of concern and their appropriate rectifying procedures are also taken into account.

Ecological degradation happens in natural fiber right from cultivation to finishing of the ultimate product. Prominent parameters and the possible package of corrective measures are highlighted. Synthetic fiber industry is not an exception to environmental pollution and therefore various pollution-creating activities are pointed out. Management of various textile wastes is also mentioned in this paper.

Advancements in Reactive Textile Dyes

The market for reactive dyes will continue to increase. This will arise partly from a marginal increase in the production of cellulosic fibres, essentially cotton, and more importantly from the replacement of other classes of cellulose dye, such as azoic and sulphur dyes, by reactive dyes.
