Different Types of Weaves in Woven Fabrics

Image
Textile fabrics are essential material for making clothes, home made-up and other apparel products. Fabrics can be classified into four types according to the fabric weave structure - woven fabric, non-woven fabric, knit fabric and braid. In this post, we will discuss various types of woven fabrics according to the fabric weaves.
What are woven fabrics Any textiles which are made from the process of weaving are called woven fabrics. Weaving is a method of textile production wherein two distinct set of yarns or threads are interlaced at a right angle to one another to form a fabric or cloth. The longitudinal yarns are called warp and the lateral threads are called weft or filling. Woven fabrics are woven in a loom whose basic function is to hold the warp threads under tension to facilitate the interweaving of the weft threads.

The characteristics of the woven fabric depend a lot on the method in which the yarns are interwoven in. The characteristics of the weave also change depending o…

Measure SMV Improvement Percentage

In the garment industry, the industrial engineering department does a lot of improvement work in a factory, like improving productivity, reducing cost per garment, setting up SOPs. The improvements they do, are measured through various KPIs. But many engineers are not yet measuring some important KPIs. One such KPI is SMV improvement percentage. The SMV reduction or SMV improvement percentage is also considered a KPI for the engineering department.

In this post, I will show you the importance of measuring SMV improvement and the formula for calculating this KPI.

Importance of measuring SMV improvement While industrial engineers aim for the production cost reduction, it is often done by reducing the standard time of the operation. The SMV can be reduced by applying workplace engineering,  method improvement, and introducing machine attachment or guides.

It is required to calculate monetary saving after introducing new SMVYou must measure all your improvement works. It will help one get …

How to Calculate Sewing Machine RPM?

Image
Do you know the speed of your sewing machines? Do you know how to calculate the machine rpm (speed)? Read this post to learn the method of calculating sewing machine RPM from seam length and SPI.

Each sewing machine has a maximum speed limit. When a sewing operator performs a task on a machine, he/she does not run the machine at its maximum speed (rpm). How fast a machine is run depends on the skill of the operators and difficulty level of the operations.

When it comes about measuring machine rpm, you can find
- the maximum speed a machine can be performed or
- at what speed operator runs a machine
- average machine speed

I have written answer of all three.

1. If you want to know what is the maximum speed limit of a machine then refer to machine manual
or sticker attached to the motor.
2. If you want to know how fast a machine can be run, use the following steps. It is a reverse process of calculating machine rpm.  Cut a fabric strip of 2 meters length and 15 cm wide.(i..e. loop lengt…

Collar Making Technology and Machines (with video)

Image
A collar is one of the most visible parts of a shirt. The collar appearance is enough to determine the value of the shirt. With automation becoming the future of garment industry various machines are being developed and implemented throughout the industries. In this post, I will show 4 different technology levels for making a collar (collar run stitch) in the readymade garment manufacturing industry.


In clothing, a collar is the part of a shirt, dress, coat or a blouse that fastens around or frames the neck. It is made from a separate piece of fabric rather than folded or cut part of the same piece of fabric of the garment. It can be permanently attached to the main body of the garment or detachable. There are various levels of technology available for collar making each having its advantages as well as disadvantages.

1. Manual sewing of collar making The most basic one is the manual sewing wherein one ply (shell fabric) is sewn over the other ply (fused fabric) with Single Needle Loc…

Defects in the Garment Industry - An eBook by Stitch Diary

Image
A defect can degrade the quality of the garment. Producing defective garment means compromising with product quality, and incurring excess cost, time and labour to make the garment saleable.

100+ different defects found in the garments which come from various sources. A defect can be classified as the source of the defect generation (cutting, stitching, printing, embroidery) and material (knit/woven fabric, trims etc).  
To make a quality garment, one needs to understand how the defects look, what is the source of the defects and how to fix the defect generation. 
Today, I am sharing the recent eBook published by Stitch Diary "Defects in the Garment Industry". You can learn a lot from this eBook. In the Ebook, you will find
Garment defects due to Dyeing & Printing Embroidery fabric defectsDefects in woven fabricsDefects in knit fabrics Defects in garment manufacturing Click here to download the free E-Book.

Chinese Apparel Sourcing - Few Insights of the Chinese Garment Industry

Image
I recently visited China to source fabric and onboard manufacturing plants for my performance sports apparel company. As someone who worked in the apparel sourcing for various companies in the past, I have visited China many times, though my most recent visit came after a gap of few years.

My first impression was astonished disbelief in the incredibly rapid development the Chinese have made in terms of infrastructure. Freeways run miles long on top of each other; some places there are two or three freeways that run parallel to each other. Public transportation is now more developed and dependable than ever. Most cities are now connected by bullet trains, which have cut travel time by almost 40%.

I had the privilege to visit multiple cities in search of knit and woven fabric mills along with manufacturing plants capable of handling woven and knit products. Some of the cities I visited included, Shanghai, Nanjing, Xiamen, Hangzhou, and Guangzhou. All are well-known apparel hubs.

Getting The Right Data To The Right People At The Right Time Whether you run multinational apparel manufacturing operations or a single factory, data should be at the heart of your organization’s strategic decision making. The important criteria is getting the right data to the right people at the right time. You’ve probably heard the buzzwords: Big Data, Predictive Analytics, and Cloud BI, and perhaps have read about the latest technology leveraging data including RFID, sew-bots, 3D scanning and augmented reality-based design and fitting and NFC- based raw materials. But with tech development happening at lightning speeds, it’s hard to know where to start and how you can make data work for you and your organization.

This issue is compounded further when it comes to data on production quality. Despite quality is the key to repeat orders, satisfied buyers and long-term profitability, manufacturers tend to invest in planning and production tracking technology few quality management or …
