Fabrics for Merchandisers
An apparel merchandiser should know about fabric as it plays a significant role in apparel manufacturing. Fabric cost constitutes 60 to 70% cost of
the product. So, the selection of fabrics should be accurate to quote competitive prices as well as quality concerns. Effective skill in the selection of fabric and its utilization optimizes garment quality and profits.
Thread Consumption Equation
Thread consumption may be carried out by an equation that is derived from stitch geometry for various stitch types. The equation is flexible and applicable to any given length of the seam, they are shown for one inch only, and may be multiplied by the length of the seam to determine the total thread consumed.
Needle Systems for Different Sewing Machine
A needle system defines the dimensions of a needle to suit the machine type. Needle systems are classified based primarily on three measurements: eye to butt length (D), shank length (N), and shank diameter (A), and specific to different stitch classes.
Industrial Sewing Needle
Needle is a sewing device designed to penetrate the fabric and create a hole so that thread can be carried through the fabric. “A sewing machine is only as good as the needle in it!”
Identification of Industrial Sewing Needles
Time Study for Garment Production
Time
study is a work measurement technique commonly used by apparel engineers to
determine the rate at which a specific operation is performed. The objective of
a time study is to develop and check production standards.
Work Measurement Techniques
Work measurement is used to determine the time
required to complete one element or one. Work measurement techniques -used by
garment manufacturers include
Productivity
Productivity refers to
the efficiency of production system. It is the concept that guides the
management of production system. Productivity is an indicator of how well the
factors of production are utilized. Productivity is measured by achievement
toward established goals based on quantitative relationship between what we
produce and what we use as a resource to produce it.
Obligations of an Apparel Engineer
To manage effectively, an executive/supervisor should identify and divide his/ her obligations to primary and secondary. He/she must first take care of primary obligations adequately. In some cases this means that secondary obligations will have to be delegated to someone under the supervisor’s authority.
Techniques of Apparel Production Engineering
The tools and techniques of apparel production
engineering aim at improving productivity by optimum utilization of plant
resources, i.e., men, materials, and methods. The various tools and techniques
of apparel production engineering are:
Industrial Engineering for apparel Industry
Apparel engineers analyze, develop, and implement methods and procedures to produce apparel products that will meet the firm's standards for quality, efficiency, and productivity. Engineers are responsible for designing processes for material handling and utilization to maximize productivity.
Motion Analysis
A motion is an
act of moving a body part. Fewer motions decrease the time and energy required
to complete an operation. Using the work aid or changing the method can often
eliminate motion. Motion can be shortened by arranging the work station so all
parts are easily accessible and as close to the operator as possible.
Method Study
Method analysis determines
the most effective means of executing each process. Operation is broken down
into elements or sequences of motion that are required to execute the operation.
When methods are studied, they cannot be viewed in isolation because each
operation is affected by the operation before it and the one after it.
Work Study for Apparel Production
“Work study is a generic term for those techniques, method study and
work measurement which are used in the examination of human work in all its
contexts. And which lead systematically to the investigation of all the factors
which affect the efficiency and economy of the situation being reviewed, in
order to effect improvement”
Techniques of Industrial Engineering
The tools and techniques of industrial engineering aim at improving the productivity of the organization by optimum utilization of organization’s resource, i.e., men, materials, and methods. The various tools and techniques of industrial engineering are:
Introduction to Industrial Engineering
“Industrial engineering is concerned with the design, improvement, and installation of integrated systems of men, materials, equipment and energy. It draws upon specialized knowledge and skill in the mathematical, physical and social sciences together with the principles and methods of engineering analysis and design to specify, predict, and evaluate the results to be obtained from such systems.”
Common Abbreviations for Apparel Engineering
Following Abbreviations may be used in apparel production engineering.
Sewing Thread Consumption
Sewing thread consumption refers to the requirement of thread per unit garment. Thread consumption is significant for cost constrain as well as uninterrupted production.
Types of Seams
A seam is a line where two pieces of fabric are joined by application of a series of stitches or stitch types with a defined geometry to one or several thicknesses of fabric material.
