The Process of Garment Manufacturing

On industrial basis there are certain areas or sequence through which garments are manufactured.
· Design / Sketch:
In the garment manufacturing the first step is designing the sketch for the dresses that have to be prepared. For this purpose the designer first draw several rough sketches in the sketch book. The designer does not go for details at this moment but he rather let his creativity flow on the paper and he draws many sketches. Later these sketches are analyzed by a panel of designers. They finally select few out of them. These few sketches are rendered in detail separately or in the form of a single collection. The designer also draws working drawings along with the sketch. Working drawings are flat drawing of the sketch and it help pattern maker in understanding the patterns involved in the construction.
· Pattern Design:
The pattern maker now develop first pattern for the designsin any one standard size. This is made by pattern drafting method and the purpose of making this pattern is to create the sample garment for test fit.
· Sample Making:
The first patterns are sent to the sewing unit for assembling them into garment. This is usually stitched on calico or muslin which is an inferior quality of fabric and it reduces cost. This sample is constructed to analyze the pattern fit and design too. After the sample garment is stitched it is reviewed by a panel of designers, pattern makers and sewing specialists. If any changes have to be made they are made at this time.
The pattern design is now taken for creating the production patterns. The production pattern is one which will be used for huge production of garments. The pattern maker makes the patterns on standard pattern making paper. These papers are made-up of various grades. The most important component, the tissue paper pattern, is made from the lightest and thinnest paper commercially available (it is not made at the pattern companies). It is called 7.5 lb (3.4 kg) basis paper, meaning that a ream of it (500 sheets) only weighs 7.5 lb (3.4 kg).
Garment patterns can be constructed by two means: manual method, CAD/CAM method. Today many companies have developed CAD/CAM because of the ease of designing patterns, fluency and precision involved which cannot be guaranteed with the manual method. Investing once into theCAD/CAM unit is worth in itself. Many buyers around the world prefer manufacturers who are using CAD/CAM methods. The production patterns created in CAD/CAM can be stored easily and they can be modified at any point of time.
A garment sewing pattern or garment fabric & patterns draft is developed by calculating, taking account of the following measurements: -
1. Direct Sample.
2. Specification Sheet/ Measurement Chart.
3. Actual body size measurements.
4. Ease Allowances.
5. Sewing Allowance.
These allowances are different for different type of fabrics and patterns.
· Grading
The purpose of grading is to create patterns in different standard sizes. Grading a pattern is really scaling a pattern up or down in order to adjust it for multiple sizes. Pattern sizes can be large, medium and small or else there are standard patterns of size 10, 12, 14, 16 and so on for different figure and statures sizes. This is generally how we get S M L XL XXL sizing. Pattern grading by manual method is a cumbersome task because the grader has to alter the pattern on each and every point from armhole, to neckline, sleeve cap and wrist etc. by using CAD it is much easier and faster.
· Marker Making:
The measuring department determines the fabric yardage needed for each style and size of garment. Computer software helps the technicians create the optimum fabric layout to suggest so fabric can be used efficiently. Markers, made in accordance to the patterns are attached to the fabric with the help of adhesive stripping or staples. Markers are laid in such a way so that minimum possible fabric gets wasted during cutting operation. After marking the garment manufacturer will get the idea of how much fabric he has to order in advance for the construction of garments. Therefore careful execution is important in this step.
Computer marking is done on speciallized softwares. In computerized marking there is no need of large paper sheets for calculating the yardage, in fact, mathematical calculations are made instead to know how much fabric is required.
· Spreading:
With the help of spreading machines, fabric is stacked on one another in reaches or lays that may go over 100 ft (30.5 m) long and hundreds of plies (fabric pieces) thick.
· Cutting:
The fabric is then cut with the help of cloth cutting machines suitable for the type of the cloth. These can be band cutters having similar work method like that of band saws; cutters having rotary blades; machines having reciprocal blades which saw up and down; die clickers similar to die or punch press; or computerized machines that use either blades or laser beams to cut the fabric in desired shapes.
· Sorting/Bundling:
The sorter sorts the patterns according to size and design and makes bundles of them. This step requires much precision because making bundles of mismatched patterns can create severe problems. On each bundle there are specifications of the style size and the marker too is attached with it.
· Sewing/Assembling:
The sorted bundles of fabrics are now ready to be stitched. Large garment manufacturers have their own sewing units other use to give the fabrics on contract to other contractors. Stitching in-house is preferable because one can maintain quality control during the processing. On the other hand if contractors are hired keeping eye on quality is difficult unless the contactor is one who precisely controls the process.
There are what is called sewing stations for sewing different parts of the cut pieces. In this workplace, there are many operators who perform a single operation. One operator may make only straight seams, while another may make sleeve insets. Yet another two operators can sew the waist seams, and make buttonholes. Various industrial sewing machines too have different types of stitches that they can make. These machines also have different configuration of the frame. Some machines work sequentially and feed their finished step directly into the next machine, while the gang machines have multiple machines performing the same operation supervised by a single operator. All these factors decide what parts of a garment can be sewn at that station. Finally, the sewn parts of the garment, such as sleeves or pant legs, are assembled together to give the final form to the clothing.
· Inspection:
Open seams, wrong stitching techniques, non- matching threads, and missing stitches, improper creasing of the garment, erroneous thread tension and raw edges are some of the sewing defects which can affect the garment quality adversely. During processing the quality control section needs to check each prepared article against these defects.
· Pressing/ Finishing:
The next operations are those of finishing and/or decorating. Molding may be done to change the finished surface of the garment by applying pressure, heat, moisture, or certain other combination. Pressing, pleating and creasing are the basic molding processes. Creasing is mostly done before other finishing processes like that of stitching a cuff. Creasing is also done before decorating the garment with something like a pocket, appliqués, embroidered emblems etc.
Vertical and form presses is automated machines. Perform simple pressing operations, such as touching up wrinkles in knit shirts, around embroidery and snaps, and at difficult-to-reach places on garments.
· Final Inspection:
For the textile and apparel industry, product quality is calculated in terms of quality and standard of fibers, yarns, fabric construction, color fastness, designs and the final finished garments. Quality control in terms of garment manufacturing, pre-sales and posts sales service, delivery, pricing, etc are essential for any garment manufacturer, trader or exporter. Certain quality related problems, often seen in garment manufacturing like sewing, color, sizing, or garment defects should never be over looked.
Sewing defects
Open seams, wrong stitching techniques, non- matching threads, missing stitches, improper creasing of the garment, erroneous thread tension and raw edges are some of the sewing defects which can affect the garment quality adversely.
Color defects
Variation of color between the sample and the final garment, wrong color combinations and mismatching dyes should always be avoided.
Sizing defects
Wrong gradation of sizes, difference in measurement of various parts of a garment like sleeves of XL size for body of L size garment can deteriorate the garments beyond repair.
Garment defects
Broken or defective buttons, snaps, stitches, different shades within the same garment, dropped stitches, exposed notches and raw edges, fabric defects, holes, faulty zippers, loose or hanging sewing threads, misaligned buttons and holes, missing buttons, needle cuts or chews, pulled or loose yarn, stains, unfinished buttonhole, short zippers, inappropriate trimmings etc. all can lead to the end of a brand name even before its establishment.
· Packing:
The finished garments are finally sorted on the basis of design and size and packed to send for distribution to the retail outlets.

Leggings: How to work them for your body type

We knew it would happen eventually. Hip '80s styling is back. Think oversized sweaters, ankle boots and yes, leggings. Here we explain how to take the runway look and make it your own.

Under miniskirts, shirt-dresses, oversized sweaters and tops, leggings are the ultimate accessory this fall. Take a cue from the runways of Versace and MaxMara -- the '80s are back in the spotlight. Great news for girls blessed with gorgeous gams, but the prospect of reveal-all legwear has the rest of us running for cover (literally!). Fear not -- there are ways to copy the trend without putting less-than-perfect features on display.

Barbara Atkin, fashion director of Holt Renfrew Canada, offers this advice for all our unique body and leg shapes.

Pear
Wear leggings with knee-high boots, layered with an A-line, empire waist or cocoon-shaped tunic-length dress. Wear the dress loose and not belted. Add some of this season's long necklaces to give your body an elongated image. Play up the top half of your torso and keep the bottom half more fluid and swingy.

Athletic
You have worked out hard, so show off your toned lines by layering your leggings with a body-skimming dress, or layer with a miniskirt and new off-the-shoulder sexy Flash dance top. Ankle boots with rounded toes and high, chunky heels will give you the right lift to accentuate your well-toned calves.

Hourglass
Your womanly curves need to be accented. Layer your leggings with a mini dress or tunic. Add a waist-cinching belt and a knee boot or a shoe with a chunky high heel and round or almond-shaped toe. Throw over the whole outfit with one of this season's must-have knit capes.

Boy-ish
Show off your cute androgynous side with skinny leggings layered with a romantic blouse: Victorian style with high lace collar. Layer this blouse with a vest and throw over the whole outfit an oversized tweed or velvet jacket. Add a jockey cap and the perfect equestrian riding boot.

Petite
Wear your leggings with a high-heeled, rounded-toe ankle boot to give you height and a leggy look. Pair it with a hot mini jumper dress layered over a fine knit turtle neck. If going outdoors, choose a trendy staple: princess line knee-length coats.

Plus-size
Leggings are the perfect underpinning for you when layered over a knit tunic and ankle-length, chunky-knit extra large cardigan. Add a knee-length boot and extra long knit or fur scarf, or splurge on the celeb-coveted extra large satchel bags -- now you have flair!

Average
Lucky you! You are not too tall, not too short, not overweight and can wear any of the above-mentioned styles. You may be average but you will always be noticed and have many options to choose from.

Remember to watch your legging wear-and-tear! Leggings are prone to bagging around the knees and bum. When they've lost their stretch-appeal, it's time to turn them in (or place them under house arrest). Consider buying two pairs of your favourite kind to reduce the wear and enjoy a full season of hot, stylish legs. +Serenity Designs
