What is nylon yarn? What are the classifications of nylon yarn? In this article,Zhejiang Dingyi New Materials Technology Co., Ltd.will answer your questions.

Nylon yarn is made of continuous filamentnylon fiber twistedtogether, smooth, soft, elongation of 20% --- 35%, good elasticity, and burning white smoke. High abrasion resistance, good spin resistance, mildew resistance, coloring degree of about 100 degrees, and low-temperature dyeing. It is widely used because of its high seam strength, durability, seam flattening, and the ability to meet the needs of a wide range of different sewing industry products.

·Product parameters of the nylon yarn

The following are its general physical properties

Wire number   Denier   Average strength (KG)

40#        210D/1x2       2.3

30#        210D/1x3       3.5

20#        210D/4         4.8

10#        210D/2x3       7.0

5#         210D/3x3       10.0

·Product categories of the nylon yarn

The raw material can be divided into three categories: natural fiber nylon yarn, synthetic fiber sewing yarn, and mixed sewing yarn.

1、Natural fiber nylon yarn

Cotton nylon yarn: Sewing yarn made from cotton fiber by refining and bleaching, sizing, waxing, and other links. Cotton nylon yarn can be divided into threadless yarn (or soft yarn), silk yarn, and waxed yarn. Cotton nylon yarn has high strength, and good heat resistance, and is suitable for high-speed sewing and durable pressing. It is mainly used for sewing cotton fabrics, leather, and high-temperature ironing clothes, while the disadvantage is that the elasticity and abrasion resistance is poor.


2、Synthetic fiber nylon yarn

Polyester nylon yarn: made of polyester filament or staple fiber, with high strength, good elasticity, wear resistance, low shrinkage rate, and good chemical stability. However, the melting point is low, easy to melt at high speed, blocking the needle eye, and easy to break the thread, so attention should be paid to the selection of machine needles. Mainly used in denim, sportswear, leather products, wool, military uniforms, etc., is currently the most used, most popular nylon yarn.

nylon yarn: Made of pure nylon compound yarn, divided into filament yarn, short fiber yarn, and elastic deformation yarn.

Acrylic nylon yarn: made of acrylic fiber with a low twist, brightly dyed, mainly used for decoration and embroidery.

3、Mixed nylon yarn

Polyester-cotton nylon yarn: 65% polyester, 35% cotton blend, both polyester and cotton advantages, high strength, wear resistance, heat resistance, good shrinkage rate, mainly used for all-cotton, polyester-cotton and other types of garments of high-speed sewing.

Core-spun nylon yarn: The strength depends on the core yarn and the wear and heat resistance depend on the outer yarn, mainly used for high-speed and firm garment sewing.


·Product applications of the nylon yarn

Nylon yarn material is twisted together to produce a yarn with certain tensile force, strong pulling force, luster, high-temperature resistance, and high speed, mainly for leather sewing, such as shoes, bags, sofa industry, etc. Nylon yarn is the most common leather sewing yarn.

Nylon yarn is used for sewing various garment materials with both practical and decorative functions. The quality of nylon yarn affects not only the sewing effect and processing cost but also the appearance quality of the finished product. Therefore, we would like to introduce the general concept of nylon yarn formation, twist, the relationship between twist and strength, sewing thread classification, characteristics and main uses, and the selection of nylon yarn, to facilitate the development of standards for enterprises to conduct relevant tests to determine the general concept of nylon yarn formation in a targeted manner.
