Standard Minute Value in Garments   Standard Minute Value   SMV, or "Standard Minute Value," is a term commonly used in the apparel industry. It's a statistic used in industrial engineering to calculate how long it takes to finish a certain operation or activity in the clothing production process. SMV supports the estimation of the overall production time, the establishment of production goals, and the assessment of operational effectiveness. Manufacturers may more effectively plan and manage their production lines, streamline workflow, and raise overall productivity by segmenting the manufacturing process into smaller jobs and giving each one a set amount of time. For clothing manufacturers to effectively meet production deadlines, cut costs, and streamline operations, this statistic is essential. What does it mean by garments SMV 42? How will you calculate SMV through time study? Answer: Garments SMV 42 indicates that a standard worker should need 42 minutes to finish

Introduction:  Knit garments merchandising encompasses a series of planned activities aimed at executing and dispatching merchandise on time, while prioritizing the 4 R's: Right Cost, Right Quantity, Right Quality, and Right Time. Functions of Knit Garments Merchandisers: Execution of Sample Orders:  Upon receiving the specifications for a sample order, it is crucial for the merchandiser to thoroughly understand the buyer's requirements. Amendments to the sample order sheet should be addressed promptly, and the merchandiser must ensure the timely execution and dispatch of samples of the desired quality. Costing: Merchandisers must consider the following details during the costing process: Yarn cost Process cost (e.g., knitting, bleaching, raising) Rates for various sewing operations Cut Make Trim (CMT) rate Ironing charges, packing charges, and accessory rates Overheads Shortage or wastage (3%) Free on Board (FOB) transport charges (2% to 3%) Insurance (2%-3%) Buyers' agent

Why combing out will be more ? Ans : • The thinner the fiber strand (sliver fineness) • The more parallel the fibers arrangement • The more highly straightened the fibers, • The smoother the fibers • The shorter the clamping distance • The optimum rotational speed of the roller. High roller speed will damage the fibers while lower roller speed would deteriorate yarn quality.

## Explain why weave design with more than 10 picks repeat is not possible to be woven by a tappet loom ?DUET-2014 Ans : all aspects apparel Suppose, we need to make a sateen weave which will require 12 tappets. So counter rotate once in every 12 picks occupies one-twelve of a revolution. i.e 30 degree the dwell period is 1/3 of pick. i.e 10 degree .The shaft will rise while the tappet turns 20 degree, will dwell during next 10 degree and will fall the next 20 degree. For this purpose, are should use larger tappet. For most looms, the lift required at the heald shaft will be between 12.5 cm to 20 cm. To use the tappet contains 10 picks, the outer diameter of the would be larger than 30 cm which is probably too large to accommodate inside the loom from.So more than 10 picks repeat is not possible by a tappet loom.

## Discuss the history of weft insertion systems.DUET-2013 Ans : Projectile weaving machine was invented in 1924 by an engineer named Rossmann became commercial in 1953. The first patent for the raper weaving machine was granted in 1898, then followed the Gabler system in 1925 and the Dewas system in 1930.Production of rapier weaving machine started in 1972. The first air-jet system was invented in 1914 but it became important commercially after 1980's. Continuous weft insertion on a circular weaving machine(multi phase) was proposed before the end of the 19th century. After mid 90's multi phase weaving machine has showed new developments.

Size of Jacquard: Design capacity of the jacquard for controlling the ends Number of independent end lifts that can obtained Virtually unlimited for the no. of picks in the weave repeat. ##What is meant by "600 needle jacquard (12*50). Ans : 12 is known as short row, 50 is known as long row. It has twelve horizontal rows of needles placed one above the other with 50 needles in each row, plus a few extra needles. Instead of no. of needles, the no. of hooks can given to define size of jacquard,say, 600-hook jacquard. Hook is the main lifting element of the jacquard shedding.
