Statistical mapping and data collection of critical equipment failures in the weaving section of textile manufacturing
The study's foundation was a scenario analysis of a textile mill's weaving department, with the goal of determining the necessity of a reliable and comprehensive plan for scheduling maintenance time. According to the background information and problem statement, incidents of Run failure maintenance and lengthy downtime (up to 60 days) undermine the machines' availability. The desired efficiency and production are 90% and 194.76 m, respectively; however, the preliminary results indicated less. This indicated a gap that must be closed by implementing regular and appropriate maintenance plans. Additionally, the incoherent and inconsistencies points at a lack of an efficient maintenance plan. It was established that the current strategy is not optimized and does not ensure machine availability because there are disparities and irregularities in the maintenance of crucial equipment. The objective of the study was to map out the critical equipment and collect data on the number and time between failures encountered in the weaving section of the textile manufacturing processes. Failure mode and effect analysis and fish‐bone diagram were used in the analysis of the data. Mapping results indicated downtime up to 60 days, the productivity was estimated at 194.76 m, and efficiency was 90%. The results showed that the critical equipment were the essential piece of machinery in the production line of a textile mill.

Manufacturing processes for textile and fashion design professionals
To be truly prized and employable, textile and fashion designers have to be aware of, and knowledgeable about, a wide range of processes to enable their designs to be manufactured effectively, often thousands of miles from their design studio. This much-needed new reference is the only encyclopedic guide to manufacturing processes and materials that is truly relevant for textile and fashion designers. It is organized into five main parts: fiber and yarn technology; textile technology; construction technology; life cycle strategies; and materials appendix. This book is a complete overview of the life cycle of textile and fashion manufacturing, from the spinning of yarn to recycling. All the processes feature detailed step-by-step case studies showing the process in manufacture at a leading international supplier. The appendix features essential knowledge on over sixty natural and synthetic materials. With around 1,400 specially commissioned photographs and technical illustrations, this is the indispensable, reliable, convenient, and highly accessible practical reference for all textile and fashion designers.-- Source other than Library of Congress.

Efficient three dimensional modelling of additive manufactured textiles
Purpose - The purpose of this paper is to investigate, develop and validate a three-dimensional modelling strategy for the efficient generation of conformal textile data suitable for additive manufacture.Design methodology approach - A series of additive manufactured (AM) textiles samples were modelled using currently available computer-aided design software to understand the limitations associated with the generation of conformal data. Results of the initial three-dimensional modelling processes informed the exploration and development of a new dedicated efficient modelling strategy that was tested to understand its capabilities.Findings - The research demonstrates the dramatically improved capabilities of the developed three-dimensional modelling strategy, over existing approaches by accurately mapping complex geometries described as STL data to a mapping mesh without distortion and correctly matching the orientation and surface normal.Originality value - To date the generation of data for AM textiles has been seen as a manual and time-consuming process. The research presents a new dedicated methodology for the efficient generation of complex and conformal AM textile data that will underpin further research in this area.

Fuzzy control charts for process quality improvement and product assessment in tip shear carpet industry
Purpose - The purpose of this paper is to demonstrate the use of artificial intelligence methods in quality control and improvement. The paper introduces a systematic approach for the design of fuzzy control charts of tip shear carpets.Design methodology approach - There are certain steps for designing fuzzy control charts. All input, state and output variables of the carpet plant and partition of the universe of discourse were first determined. The interval spanned by each variable and the number of fuzzy subsets each assigned with a linguistic label were identified. Then, the adaptive capability of neural network was used to determine the membership functions for each fuzzy subset. The fuzzy relationship functions between the inputs and outputs were assigned to form the fuzzy rule base (controller) in order to normalize the variables and certain intervals. Fuzzification of input parameters and max-min composition of rules for inferring crisp outputs was the next step. The aggregation of fuzzified outputs and defuzzification of the outputs were the last step of this study, which helped to produce crisp outputs for latex weight.Findings - Fuzzy linguistic terms were employed for overall quality assessment and rating of the end product. The outcomes of neuro-fuzzy system were good supplements to other statistical process control tools.Research limitations implications - Lack of qualified domain experts, knowledge acquisition of process parameters and time limitation for training of neuro-fuzzy model were primary limitations.Practical implications - The approach is more flexible and meaningful to identify the quality distribution of a product. The qualitative aspect of human reasoning for decision making was employed in this approach.Originality value - The paper is original and the first such work for local industry.

The impact of the setting of airjet looms on the fabric quality an investigation
Purpose The purpose of the paper is to provide a methodology aimed at improving the setting up of airjet looms by clarifying the function which links different important variables involved in the setting procedure and by proposing a method to measure the quality of fabrics depending on the factor values. Designmethodologyapproach The proposed procedure is based on the use of a load sensor the tension profile received from it is used to analyse the weft behaviour and, sometimes, to predict any quality problems. Because of the high number of variables influencing the set up, the factorial experiments have been used to develop the setting procedure. Numerical results have been analyzed by means of a regression analysis and an ANOVA analysis. Findings Relationships among different variables and their influence on the quality of the fabric have been derived thanks to the use of a load sensor. Research limitationsimplications So far, the proposed procedure has been developed for airjet looms and for a limited set of fabrics, but it could be adapted in other situations as well. Practical implications Use of the proposed procedure allows practitioners to reduce cost and time of the setting up of air jet looms. High productivity of air jet looms could be thus better exploited also for producing small batches of products. Originalityvalue The combination of the load sensor and the statistical analysis allowed the development of a systematic setting procedure for airjet looms.

Technology adoption by apparel manufacturers in Tirupur town, India
Purpose - The purpose of this paper is to examine the status of technology adoption of Indian apparel manufacturing firms and the organizational factors that affect the level of technology adoption.Design methodology approach - Fourteen technologies applicable to apparel manufacturing were examined. A survey with an online questionnaire to apparel manufacturers in India was conducted to collect the data.Findings - The most frequently adopted technology was the internet. The least frequently adopted technologies found in this study were robot-related. The level of a firm's technology adoption was found to be significantly related to firm size positively and its export orientation negatively. It was also moderately related to competitive advantage. The effects of top management commitment, cost of capital, and technical skills were not significant.Research limitations implications - Generalizability of the results is cautioned because the data were from the firms in one industrial town. The results indicate that technology adoption is related to the recent, intensified trade competition. The relationships among export orientation, price competition, and technology adoption need to be studied further.Originality value - Given the importance of upgrading in today's competitive global trade environment, this study builds a knowledge base of the technology adoption in apparel manufacturing and influential factors in developing countries.
