Silk fabric was simultaneously modified with itaconic acid and Allium cepa and itaconic acid and Terminalia arjuna in presence of potassium sodium tartrate as esterification catalyst and potassium peroxodisulfate as free radical polymerization catalyst using a dip-dry-iron-cure technique. Treatment of silk with 6% itaconic acid, 6% potassium sodium tartrate, 0.5% K2S2O8 and any of the above mentioned dyes with subsequent spin drying at 70°C followed by ironing of dried fabric at 70°C and curing of ironed fabric at 140°C for 5 minutes produced most balanced improvements in respect of depth-of-shade, wrinkle recovery, colourfastness to light, wash and rubbing with retention of more than 88% of the original strength. IR analysis of dyed silk fabric indicated that treatment of silk with itaconic acid and either of the above dyes under dual influence of esterification catalyst and free radical polymerization catalyst led to some degree of cross-linking of chains polymers of silk.

A pattern is a guide for cutting the fabric which can be sewn together to form a garment. 2 The different types of pattern making within the apparel industry are: AbstractToday's garment-making technology has exceeded expectations, has become easier to learn and quickly adapt completely to the specific necessities of apparel designing. The fit is the most significant deciding factor related to the final acceptance or rejection of a garment. Getting to right design is as important as getting a right product with a perfect fit. The well-tailored fit is dependent on the pattern drafting integrating dimensions of the fit model having various shapes, contour and proportions. With the beginning of the industrial revolution and advances in textiles and clothing manufacturing, standardized patterns were vital to the success of ready-to-wear clothing. New technology platforms are facilitating greater flexibility in the areas of pattern designing, grading, marker making, waste reduction, increase in efficiency and accuracy of the cutting room and create accurate samples in time to help reduce costs are some advantage of using of computer-aided design (CAD) system in composite garment manufacturing. Increase in product development costs, the rise in shipping charges, and awful decision making are an entity that many businesses cannot afford. Efforts are required to drive a product to get to the market faster and are saleable. With that in mind, use of advanced technology in apparel manufacturing is an essential competitive advantage for retailers, brands, and manufacturers alike. This paper was designed to understand the various methods of pattern making systems.Citation: Datta DB, Seal P. Various approaches in pattern making for garment sector.Citation: Datta DB, Seal P.

Background: Keeping in view the great variations in different dimensions of the human trachea and its remarkable clinical importance, the present work was undertaken. It included the study of dimensions of adult trachea of both sexes in West Bengal population. In addition, an effort was made to establish their relationship with selected external measurements. Methods: This was a cross-sectional, observational study on 60 cadavers. Relatively disease-free fresh adult cadavers were selected from West Bengal population. Study variables were tracheal length, internal transverse diameter and internal anteroposterior diameter. Selected external measurements were height and sternal length. Results: In males, the highest correlation was observed between tracheal length and height (r = 0.800), and tracheal length and sternal length (r = 0.799). In females, the highest correlation coefficient was found between tracheal length and height (r = 0.809). Conclusion: Different formulae were obtained by linear regression with all measurements being in centimeters. Therefore, it is possible to predict the tracheal dimensions from simple external measurements.
