The creation of Silk and why your yarn will last longer then the Sari it’s made from
Okay so I received several questions about why the silk ribbon would be durable for projects when the silk sari only last for a few years. So let me see if I can answer that question with more then just “I said so”.
Silk is one of the costliest natural fibers and is preferred for its fine quality and gracious
look. Quality control is the most effective measure to maintain the quality of the
raw material, yarn, or fabric. Therefore, most modern mills adopt separate testing
departments for the purpose of quality control. Silk is an exclusive natural protein
fiber with the unique feature of high strength and light weight. The warmth properties
are comparable to that of wool; silk exhibits excellent feel/handle properties. The natural
silk fiber is also very fine, and thin fabrics can be prepared from it. The test method used for silk fiber and yarn are different from that of other fibers or yarns, as the inherent characters are different for silk.
Raw silk is the silk yarn with natural gum sericin and without any twist. It is also
known as reeled silk yarn or water reeled silk yarn. Generally, the testing
of raw silk is based on the procedures laid down by the International Silk Association; China, Japan, and India follow other standard methods. For classification purposes, raw silk is divided into three categories according to its size:
First Category: 18 denier and below
Second Category: 19–33 denier
Third Category: 34 denier and above
As per the ISA method, there are 13 test parameters that are assessed for quality characteristics. These parameters are used for the classification of raw silk and include: winding breaks, size (denier), standard deviation of size, maximum deviation of size,
evenness variation I, evenness variation II, evenness variation III, neatness, low neatness,
cleanness, tenacity, elongation, and cohesion. The test report also includes the information on the results of a visual examination of lot. Skein finish inspection results during winding, color and hand values of the sample are the properties that are considered.
The results of the visual examination and skein finish inspection are used in the classification of raw silk.
The objective of raw silk testing and classification is to determine the grade using
the results of quality tests/parameters to establish a standard not only to facilitate fair
and equitable transaction, but also to improve the quality by the manufacturers as well
as suitable selection by the consumers.
That’s the starting point for Sari Silk. Once you combine all the threads together to make something much thicker it’s also much stronger. Think on it and let me know.
