Calculating Sewing Floor Capacity

For supervisors or production managers is very important to know the floor capacity to plan their production efficiently.  Calculation of capacity is very simple but you must know the line efficiency. The other important factor to calculate floor capacity is manpower absenteeism%.


So you must know the line wise efficiency and absenteeism %. You can calculate the efficiency in minutes or hours.


Calculating Button Sizes

Button Size

Ligne is a French word, which means, "line" and it is shortened with the letter of L. Button sizes are recognized worldwide with “L”

ligne is a linear unit (1/40 inch) used to measure diameter of buttons


How to measure the button

Before calculating button line we should know following measurement:


Productivity and efficiency calculation

Productivity calculation

Most of the industrial engineers calculate worker/line efficiency on the basis of SAM value and actual productivity (per hour productivity of a operator/line). Below are the simple methods to calculate worker/line efficiency and productivity.


Worker/line efficiency

SAM (Standard allowed minutes) of the garment = 10


“TIMWOOD” 7 Wastes of Lean Manufacturing

The seven wastes of Lean Manufacturing are what we are aiming to remove from our processes by removing the causes of Mura and Muri as well as tackling Muda directly. But what exactly are the seven wastes of Lean Manufacturing (or 7 Mudas)?

The Seven Wastes of Lean Manufacturing are;

1)Transport,   2)Inventory,   3)Motion,   4)Waiting,   5)Over Production,   6)Over-Processing,   7)Defects


Novozymes’ new technology offers cold bleaching to denim manufactures

Diverse denim looks can be achieved with the latest enzymatic innovation. Working with cold water and reducing the use of the chemicals, the solution quickens the denim bleaching process, and secures higher quality denim.

Almost 20 years ago, denim bleaching became safer and more sustainable with the launch of Novozymes DeniLite®. Using enzymatic technology instead of harsh chemicals, the solution offered a gentle alternative for denim processing. Novozymes’ latest offering is a cold bleaching product known as DeniLite® Cold.


What Care Symbols Mean?

The care label describes the allowable treatment of the garment without damaging the textile. Whether this treatment is necessary or sufficient, is not stated. A milder than specified treatment is always acceptable. The symbols are protected and their use is required to comply with the license conditions. Incorrect labelling is prohibited. A bar below each symbol calls for a gentler treatment than usual and a double bar for a very gentle treatment.

A laundry symbol, also called a care symbol, is a pictogram which represents a method of washing, for example drying, dry-cleaning and ironing clothing. Such symbols are written on labels, known as care labels, attached to clothing to indicate how a particular item should best be cleaned. There are different standards for care labels for the different countries/regions of the world. In some standards, pictograms coexist with or are complemented by written instructions.

Coats Colour Express is a revolutionary web-based service that provides you with the world's fastest, most accurate thread sampling service for industrial sewing thread.

With tight sampling deadlines in the industry today, buyers receiving samples in right time with right colour match is a key issue right from design development to the finished product. Coats has taken a closer look at the current thread sampling process and redesigned it for optimisation at various levels from technology to process. This is called Coats Colour Express.


Needle Number System

The size of a needle is generally represented in one of two ways (although there are others). One method is by a number metric (Nm). This represents the diameter of the needle blade in hundredths of a millimetre measured just above the scarf but not at any reinforced part of the blade. For example, a Nm 110 needle is 1.1 millimetre in diameter, while a Nm 50 needle is half a millimetre in diameter.

The thickness of the blade on the right is 1.1mm wide which is shown in Nm as 110.

The alternative standard needle sizing method is the Singer/Asia numbering system sometimes referred to as the American system that uses a number that represents a size.


Screen Printing

Screen printing is a printing technique particularly suited for flat or relatively flat surfaces. The heart of the process involves a fine mesh or screen that is tightly stretched around a rigid frame. The areas that are not to be printed are masked out on the screen. To create the print, the framed screen is positioned over the item to be printed along with a dollop of thick ink. A squeegee is then used to press the ink through the screen.
