What Is The Thickest Yarn Called?

In the rich world of textile materials, the thickness of yarn is one of the key factors affecting its performance and application. From light and delicate silk yarn to heavy and rugged specialty yarn, yarns of different thicknesses play a unique role in various textiles. Among the many yarns, the thickest yarns show irreplaceable value in specific fields due to their special physical form and properties.

 

Indicators and definitions of yarn thickness

In the textile industry, Thick Nylon Yarn is usually measured by indicators such as Tex, Denier (Dtex), Imperial Count (S) and Metric Count (Nm). Tex refers to the weight of 1000 meters of yarn at the standard moisture regain. The larger the value, the thicker the yarn; Denier refers to the weight of 9000 meters of yarn at the standard moisture regain; Imperial Count refers to the number of 840 yards (1 yard = 0.9144 meters) of cotton yarn weighing one pound (453.5 grams) at the standard moisture regain, that is, the number of yarns; Metric Count refers to the number of meters of yarn length per gram at the standard moisture regain. Generally speaking, yarns with larger Tex and Denier values, or smaller Imperial Count and Metric Count values, are thicker yarns. The thickest yarns usually reach a higher value range in the industry in terms of these metrics. They look and feel noticeably thicker and are also unique in textile technology and application.

 

Common types of the thickest yarns

(1.) Coarse wool yarn

Coarse wool yarn is one of the common thicker yarns, generally referring to wool yarns with a count of about 6-12. It is made of high-quality wool raw materials and a special spinning process, with thick and fluffy fibers. This yarn has good warmth retention and elasticity, soft and textured feel, and is often used to make heavy winter sweaters, scarves, blankets and other textiles, which can bring a warm and thick touch experience to users.

 

(2.) Industrial roving

Industrial roving covers a variety of materials, such as coarse nylon yarn and polyester yarn. The tex number of these yarns is usually several hundred or even higher, and they are characterized by high strength and high wear resistance. In the industrial field, they are mainly used to manufacture ropes, safety belts, canvas and other products. For example, heavy ropes used in port hoisting and car seat belts all rely on the strong load-bearing capacity and durability of industrial roving to ensure operational safety and normal operation of equipment.​

(3.) Special Art Yarns​
Special art yarns are created to meet the needs of creative design and decoration. They are often made of mixed fibers or special materials. They are rich in variety and have large differences in thickness. Some products belong to the category of the thickest yarns. This type of yarn uses a unique spinning process to present special structures such as loop yarn, knot yarn, chenille yarn, etc., which are extremely visually impactful in appearance. In textile art creation, home decoration fabrics and high-end fashion design, special art yarns add artistic atmosphere and personal charm to the works with their rugged and unique style.

 

Application fields of the thickest yarn

(1.) Clothing and accessories

In clothing production, coarse wool Nylon Yarn For Sock Knitting is often used to create thick coats, sweaters and other items in autumn and winter. Its heavy texture and good warmth retention can protect the wearer from the cold, and the unique weaving texture can also enhance the fashion sense and layering of the clothing. In addition, accessories such as scarves and hats made of thick yarn are not only practical, but also can be used as fashion matching items to show individual style. In some high-end fashion shows, designers often use special art thick yarns, combined with innovative design concepts, to create highly artistic and topical clothing works, leading the fashion trend.

 

(2.) Home decoration field

In home decoration, the thickest yarn plays an important role. Blankets made of coarse wool yarn or special art yarn are soft and thick, adding a warm and comfortable atmosphere to the home space; curtains, sofa covers and other fabric products made of industrial coarse yarn are strong and durable, and can withstand frequent daily use and washing. At the same time, their rough style also brings a unique visual effect to the home environment, suitable for decoration styles such as industrial style and Nordic style. ​

(3.) Industrial manufacturing field​
The application of industrial coarse yarn in industrial manufacturing is indispensable. In construction, safety nets and lifting ropes made of coarse yarn ensure construction safety; in the logistics and transportation industry, sacks and cloth bags woven with coarse yarn are used to load cargo; in the field of shipbuilding, cables made of coarse yarn ensure the safety of ship docking and navigation. These applications fully demonstrate the powerful practicality and reliability of the coarsest yarn in the industrial field.

 

Comparison of experimental data of the performance of the thickest yarn and ordinary yarn
In order to intuitively show the performance characteristics of the thickest yarn, coarse wool yarn (10s), industrial nylon roving (500Tex), special chenille art yarn (coarser specifications) and ordinary fine cotton yarn (40s) were selected for performance testing. The results are as follows:

Test items	Coarse wool yarn	Industrial nylon roving	Special chenille art yarn	Ordinary fine cotton yarn
Linear density (Tex)	Approx. 100	500	about 200	about 15
Breaking strength (N)	120	2500	80	30
Breaking elongation (%)	35	20	28	8
Weight per unit area (g/m²)	280	450	320	60
Softness score (1 - 10 points)	7	3	8	9

 

From the experimental data, it can be seen that the  Nylon Stretch Yarn is significantly better than ordinary fine cotton yarn in breaking strength and unit area weight, reflecting its high strength and heavy characteristics; in terms of breaking elongation, coarse wool yarn and special chenille art yarn perform better and have a certain elasticity; in terms of softness, ordinary fine cotton yarn is the best, and the thickest yarn has relatively low softness due to its coarse fiber. ​

Development trend of the thickest yarn industry​
With the growth of consumer demand for personalized products and the continuous advancement of textile technology, the thickest yarn industry has ushered in new development opportunities. In terms of material research and development, enterprises will be committed to developing more environmentally friendly and high-performance coarse yarns, such as using recycled fibers to make industrial coarse yarns to improve the sustainability of products; in terms of process innovation, by improving spinning technology, the structure and performance of the thickest yarn are optimized, so that it has both rough style and good softness and comfort. At the same time, in the field of design, the thickest yarn will be more combined with fashion trends and artistic creativity, expanding its application space in high-end clothing, home decoration and other fields, and meeting the diversified needs of the market.
