What is composite polar fleece fabric? Is it the same fabric as Polartec?

Let me break it down to help you answer:

Polar fleece, also called sheep velvet, is a kind of knitted fabric. It was produced in Taiwan, China, in the early 1990s. It is a small nugget knitted structure, which is woven on a large circular machine. Various complex finishing processes such as napping, combing, shearing, polarizing, etc. The front side of the fabric is napped, and the polarizing particles are fluffy and dense but not easy to shed or pilling. The back napped is sparse and evenly balanced, with short hairs, clear texture and soft elasticity. Great.

The ingredients are generally polyester.

The composite polar fleece is made of polyester DTY75D network yarn as the primary raw material and is woven on a warp knitting machine with a plain weave. The grey fabric is first dyed and processed by various complex processes such as napping, combing, shearing, and polarizing. The front side of the material is napped and shaken. The grains are fluffy and dense but not easy to shed and to pill. The reverse side is sparse and evenly drawn, the fluff is short, the texture is clear, and the soft elasticity is excellent. It reflects the characteristics of knitted warp knitting products. Choose two pieces of cloth and use imported glue on the reverse side. The face cloth and the base cloth are bonded together to produce a two-tone effect.

Polartec is a textile material launched by Malden Mills in the United States. Its scientific name is a fleece. It is made of ultra-fine chemical fiber made into wool yarn, woven into the fabric, brushed with a metal wire brush, and the surface is then machined for shearing. Fabric. It belongs to high-grade materials for outdoor garments.
In short, these three fabrics are chemical fiber fabrics, and they are different. Polar fleece and composite polar fleece belong to scientific names, just like dogs, ducks, and duck feathers. It is a product category name. Polartec It is a high-tech outdoor fleece fabric developed by Malden Mills in the United States and patent.

The operating technology of fleece and fleece is also different:
Polar fleece: In the manufacturing process, there is a process called polar fleece, which is rolled in a machine like a drum washing machine (polar fleece) to form a small spherical particle effect on the surface.
Fleece: It’s just the effect of grabbing the fluff with the machine, and there is no particle effect like fleece
The polar fleece manufacturing process will have several more steps.

Therefore: composite polar fleece and Polartec are not the same.
