Even a small sewing thread failure leads to losses on investments in material, equipment, garment engineering, and labour. Sewing performance and seam quality could be influenced by sewing thread parameters, selection of proper thread and utilization of thread. Sewing threads is a unique type of yarn, engineered and constructed to pass through a sewing machine swiftly. The fundamental function of a sewing thread is to produce aesthetic and performance in stitches and seams (Coats 2003; Shaeffer 2000).
5.1.1 Factors affecting aesthetics of sewing thread
Fineness/thickness, colour and lustre must be taken into account when selecting a sewing thread for decorative purposes such as embroidery. Other considerations include:
• Hue and shade matching

As like other textile materials, sewing threads are composed of a fibre type, yarn construction and a finish, all have an influence on appearance and the performance of the thread. Extensive ranges of sewing thread sizes are available; the selection of size relates to the requirements of the fabric being sewn and the size of sewing machine needle used (Shaeffer 2000; Blackwood & Chamberlain 1970).
5.1.4 Properties of Sewing Thread
Requirements of good quality sewing thread are given below:
Good tensile strength to grip the seam firmly during wash and wear. It should be able to withstand a number of kinetic movements during sewing a garment. The sewing thread strength should be higher than fabric therefore it will not rupture during wear.
Higher Initial modulus of sewing thread guarantees the least thread deformation during shock loading in sewing. The sewing thread should be moderately stiff to form the loops for stitch formation.
Smooth surface and negligible faults in sewing thread provides minimum friction between the sewing thread and needle while sewing at high speed. The thread must be well lubricated to increase its sewability and resistance to
When examining textile damages, such information like the size of the knife blade and the types can be estimated. The more distinctive the weapon is, the more unique the features in any damaged apparel and therefore the stronger the association. In the blades of a weapon, the sharper ones will cut the fibres and yarns as it enters the fabric with little or no distortion; whereas the blunter ones maximises the distortion of the fabric and the disorder of the yarn and fibre ends. Scallops, imperfection and serration characteristics on the blade of a weapon increase fabric fraying and distortion. It has been reported that the dimensions on fabric when stabbed do not accurately reflect the dimensions of the knife blade.
3.10 Preload: Quantity of tension or pre applied force set into an effect to get rid of movability in mechanical assemblies. This is applicable to screw and nut mixtures, still as linear bearings. For ball screws, this reduces axial and radial play and will increase stiffness and repeatability.
Additionally, cotton and silk were used for women’s clothing more often than men’s. Women’s clothing trends are broken into three categories— rich, poor, and children's.
Different chemistries and production methods of these fibers give them certain advantages. as viscose’s ability to combine with other fibers to create new fabrics easily) and disadvantages. such as nylon’s quickly weakening fibers or natural silk’s difficulty of production. other that make them more or less suitable for certain purposes. For this reason, when? considering silk and artificial silk, it is illogical to pick one fiber that is superior to the others.
Imported cloth from India was extremely popular in Great Britain during the eighteenth century. According to the book the industrial revolution, British entrepreneurs saw the profit to this trend, importing raw cotton from India or the American colonies and producing cloth locally. Since the demand for cloth was so high and growing, they discovered that they wouldn’t be able to supply fast enough. They then began to search for ways to accelerate the process of spinning the cotton into thread and weaving the cloth. Thankfully, John Kay improved the shuttle, which was a device, used by weavers to pass horizontal threads through the vertical threads strung on a loom. His invention, the flying shuttle, allowed weaver to send the shuttle rapidly across the loom simply by pulling on a
Also, the color that is the weavers weave in the cloth and different fabrics have various colors, some broken colors, the grays have the most vibrant colors that balance each other out into a harmonious palette from a distance.
The history of sewing machines started with someone’s need, which so many others felt they needed, too. Sewing machines made the lives of housewives much easier. Sewing by hand took long hours and was not productive. Many girls would have to learn how to sew at a young age in order to know how to sew once they were married.
The strengths of the book come from its’ accessibility. The book is easy to follow and provides readers with a great deal of information about the production of mass-manufactured clothing. As well as brings awareness to its’ many issues which we inadvertently take part in when we purchase such products. The book is well written and thoroughly researched but does have its’ share of weaknesses.
This new invention had many better qualities and/or abilities than any other material in use already. Nylons are mostly known for their abilities to be dyed, to be unharmed by many kinds of household cleaning products or greases and oils, its rapid drying time, and above all, its silk-like appearance (The World Book). Nylons¡¯ tensile strength is greater than that of cottons, rayon, silk, and wool (Encarta). They also have characteristics that include elasticity, easy to clean,...
While the price of cotton textiles decreased by 90%, the output had grown to cover the demand at affordable prices. Now, cotton will be gotten from Brazil, Egypt, southern United Sates and all this meant a...
Weaving is a common thread among cultures around the world. Weaving is a way of producing cloth or textile. Today we have machines that weave large-scale textiles at cheap prices. Production of cloth by hand is rarely engaged in today’s Westernized societies. Not many people are thinking about how the fibers are actually constructed to make their clothes. However, in other cultures across the world the tradition of weaving still exists. By comparing three cultures that continue weaving as a part of their tradition we can see similarities and the differences between them. The reasons that each culture still weaves vary, as do the methods and materials. The desired characteristics of the cloth also vary around the world as each culture values different aesthetics.
During the Industrial Revolution, the textile industry received high demand for its cloth goods. However, the production of such goods was very slow. As demand rose, the need for a faster, cheaper, and more efficient way of producing enough cloth goods became more urgent. Thus, inventors began developing new ways to produce cloth goods. One of the best examples was English inventor James Hargreaves. Hargreaves invented the spinning jenny, a device in which spinners would use his right hand to quickly spin a wheel to rotate spindles and spin 8 threads around 8 spindles attached to a wooden frame. Since each spinning jenny could spin several threads simultaneously, the device dramatically increased the rate at which cloth was produced and the quantity of cloth that was made. This allowed for the textile industry to meet the large demand for cloth goods of the time and enhance their method of produ...

First of all, the fibres can classified as natural or man-made fibres. Natural fibres are those obtained from the natural resources on the environment, whereas the man-made fibres could be synthetic or regenerated fibres. Synthetic fibres are completely made from chemicals while regenerated fibres are those originally from natural resources unsuitable to be used as fibres directly, processed chemically to be changed into textile fibres. In this assignment, we will study on the general textile manufacturing processes as listed below. Then, it is hoped that the knowledge on general process could help us understand more on the industry as well to relate it with the environment.
From 2005 the textile segment has been made up of 2 companies, transforming raw materials into fabrics, from spinning to finishing and ennobling. Handicraft product quality and technological research development characterize this business segment which works with internationally recognized names of the apparel and fashion industry.
