Sewing Thread Consumption & Methods

In today’s competitive marketplace, there is a need for tight cost control. A realistic estimation of potential thread requirements for particular garment styles or contracts will not only end up saving you money, but also enable you to use a superior thread for the same cost, thereby not compromising on garment quality.

Several factors determine the extent of thread consumption in any sewn product, such as stitch type, seam type, material thickness, number of layers, construction and SPI (stitches per inch).

However, these factors are not constant with the different style preferences. Hence, thread consumption is never standard for sewn product categories such as shirts, trousers and footwear.

There are two methods generally used to calculate the amount of thread in a seam and

All about yarn & yarn types?

To convert textile fibers into fabrics some type of fiber arrangement is required.Probably the most common method is to convert fibers into yarns, which are then constructed into fabrics. Yarns are essential for knitted, woven or knotted structures and for many braided ones.

‘Yarn’ is defined by the American Society for Testing and Materials (ASTM) as “A generic

term for a continuous strand of textile fiber, filament, or material suitable for knitting, weaving to form a textile fabric. Yarn occurs in the following forms.

Yarn forms:

(a) A number of fibers twisted together.

(b) A number of filaments laid together without twist.

(c) A number of filaments laid together with more or less twist.

(d) A single mono filament. e.g. Silk

Seam or Stitch types & classification?

Introduction:

In sewing, a seam is the join where two or more layers of fabric, leather, or other materials are held together with stitches. Seams in modern mass-produced apparel, footwear, house hold textiles and sporting goods are sewn by industrial sewing machines. Home shoe making, dressmaking, quilting, crafts, haute couture and tailoring may use a combination of hand and machine sewing.

In clothing construction, seams are classified by their type (plain, lapped, bound, flat) and position in the finished garment (center back seam, inseam, side seam). Seams are finished with a variety of techniques to prevent raveling of raw fabric edges and to neaten the inside of garments.

Seams used for assembling sewn products are load bearing and ideally should be similar in physical properties to the material being sewn. The stitch type and sewing thread used will vary with each application. Hence, it is important to be familiar with various seam types, their applications and variations available so that you can choose the right seam to suit your sewing

Why all the fibers are not textile fiber?

According to maximum textile Specialists, to be a textile fiber its must be 500 to 1000 times longer than the width. Every fiber around the word can’t be a textile fiber because a textile fiber has its own specified properties is include Sufficient Strength, Length, Fineness, Elasticity, Crimp, Friction, Ability to react with Acid & Alkali’s and should have the power to protect the effect of biological agent too. Wool, Cotton, Nylon all of them has the requirement to be a fiber on the other hand, may be banana tree has some of the quality to be a textile fiber but it’s not enough. So we can’t precede banana tree is a textile fiber, similarly we also can say all the fiber in the world is not textile fiber expect some which are fill the requirement to be a textilefiber.

If we know about textile fiber then we’ll get why all the fibers are not textile fiber? Textile is special fiber which used to make textile or garments product. Basically we know textile fiber are come from two different source like nature and synthetic. Synthetic fiber also called man made fiber or artificial fiber. Natural fiber is so much comfort to use as a garment and its friendly with nature. On the another hand synthetic fiber is made by human and its not come from nature. Synthetic fiber made from mixing proper unit of chemical as it can make yarn and possible to weave or knitting to make garments. Mostly natural knitting technology used cotton fiber. Cotton fiber is reliable fiber across the world. its mostly used natu This is a little discussion about textile fiber because this is not written about fiber. pleasefollow the link to read more about classification of textile fiber.

What is Difference between “Natural fiber and man-made fiber”?

Natural fiber and man-made fiber:

Textile is a technology depends on fiber. Fiber is a things which is used to make yearn and fabric. Fiber is come from two different sources. Two source of fiber is Natural fiber and man-made fiber also called Synthetic fiber. Natural fiber is comes from nature, that’s why it’s called natural and on the other hand when the human make a fiber to us those alternative by natural fiber and its makes from different type of chemical in a factory is synthetic fiber. Synthetic fiber is made by human so that it’s called man-made fiber. Click here to the classification of fiber  

Difference between “Natural fiber and man-made fiber”.

Natural Fiber	Man-made Fiber
The natural fibers we get from nature are called natural fiber.	The fiber made by synthetic or regenerating system called man-made fiber.
In the natural fiber molecules are not limited.	In the man-made fiber molecules are limited as the producer want.
The numbers of molecules are controlled by nature and the length cannot be controlled by nurture.	The numbers of molecules are controlled by man & the length can be control.
Natural fiber is comfortable and it’s good for health.	Man-made fiber is not comfortable and it’s not good for health.
Its expensive fiber.	It’s not so expensive fiber.
The strength of natural fiber is low.	The Strength of man-made fiber is high.
The productions of natural fiber depend on nature climate and environment	The MM f can be produce with local materials and chemicals. It is not depend on nature.
It’s not much favorable for finishing.	It’s favorable for finishing.

What is Recycled Yarn? And Is Recycled Yarn Better?

 What is Recycled Yarn?

Recycled yarn is any yarn that contains fibers that were once used for something else. Probably the first such yarn available was the recycled silk yarn, made from the end bits left over from sari production.

These days you're beginning to see more yarns made with recycled cotton or plastic content.

Recycled cotton yarn typically comes from the remnants left over after manufacturing T-shirts, while plastic fiber is extruded from recycled plastic bottles. You'll sometimes see this referred

What is Organic Cotton Yarn?

Organic yarn means that the fiber the yarn is made from was produced without the use of man-made chemicals such as herbicides, pesticides or chemical fertilizer.

When the fiber comes from an animal, the animal must be fed organic feed and raised under organic standards.

Growing cotton accounts for as much as 16 percent of global pesticide use. Of course all of that does not go to make yarn--it's used for T-shirts, sheets, bedding and countless other products.

Pesticide use is harmful to both the people who have to live and work around pesticides and the planet when pesticide runs off from where it was

Different types of sewing problem & solution to sewing problem?

Common sewing problem: Causes and Remedies

There can be many reasons behind the problems that arise while sewing and knowing the cause of these problems and a solution for each particular cause is essential. These problems can be minimised by avoiding errors during handing of materials / machines and by following the right working methods.

Some common sewing problems are;

1. Needle thread breakage
2. Bobbin or looper thread breakage
3. Thread fusing when the machine stops
4. Skipped stitches
5. Imbalanced / variable stitching
6. Staggered stitching
7. Variable stitch density
