Intermingled yarn

In the production of Synthetic yarn, especially elastic yarn with plies or a combination of two materials, the mingling technique dramatically impacts the physical properties of the final product. In Derun's factory, textured yarn and air-covered yarn can be fed into a nozzle with compressed air and be intermingled.

NIM (Non-Intermingled), SIM (Semi-Intermingled), and HIM (High-Intermingled) yarns are three types of synthetic yarns that are commonly used in the textile industry. These yarns differ in the level of intermingling between the filaments and their physical properties. Here are some differences between NIM, SIM, and HIM yarns:

1. Level of intermingling: The level of intermingling between the filaments is the main difference between these yarns. NIM yarns have no intermingling (0-10 knots per meter), SIM yarns have a low to medium level of intermingling (40-50 knots per meter), and HIM yarns have a high level of intermingling (100-120 knots per meter).

2. Filament arrangement: The arrangement of filaments in NIM, SIM, and HIM yarns is different. NIM yarns have parallel filaments that are not twisted or intermingled. SIM yarns have slightly twisted filaments that are partially intermingled. HIM yarns have filaments that are highly twisted and tightly intermingled.

3. Physical properties: The physical properties of NIM, SIM, and HIM yarns are different. NIM yarns have low elasticity and bulkiness, while SIM yarns have moderate elasticity and bulkiness. HIM yarns have high elasticity and bulkiness, making them more suitable for use in stretch fabrics and other applications where a high degree of elasticity is required.

4. Production process: The production process for NIM, SIM, and HIM yarns is different. NIM yarns are produced without any additional processing after extrusion and drawing. SIM yarns are produced by partially intermingling the filaments during the texturing process. HIM yarns are produced by highly intermingling filaments during the texturing process.

Intermingled yarn is a type of synthetic yarn that is used in various textile applications. The intermingling of the yarns during this process creates a more stable and stretchable yarn with improved properties. The quality of the intermingled can be improved by controlling the process parameters such as the air pressure, nozzle design, and heat-setting temperature and time to create a stable and stretchable product.
