Polar fleece fabric(also known as anti-pilling polar fleece fabric) is a kind of knitted fabric woven by a large circular machine. After weaving, the grey fabric is first dyed, and then processed by various finishing processes such as napping, combing, shearing, and pilling. The front of the fabric is brushed and pilled.
This article will discuss the characteristics of polar fleece fabric, the advantages and disadvantages of fleece fabric, the types of fleece fabric, the use of fleece fabric, the principle and technology of fleece fabric production, and the answers to common questions and answers of fleece fabric. Explain what is polar fleece fabric.
1. What are the features of anti-pilling polar fleece fabric
- Polar fleece fabric is a kind o fabric which is dense and fluffy, but not easy to shed hair or pilling.
- The back side of polar fleece fabric is sparsely and well-proportioned, the fleece is short, the texture is clear, fluffy, and elastic.
- Its materials are generally polyester and soft to the touch. It is the first choice for keeping out the cold in winter.
2.What are the advantage and disadvantage of anti-pilling polar fleece fabric?
- It is not easy to shed or pilling.
- Good heat preservation effect.
- Polar fleece fabric can also be combined with all fabrics to make the effect of keeping out the cold better.
The polar fleece fabric complicated processing is easy to have problems. Besides, it is easy to generate static electricity like all-polyester fabrics.
3.The classification of anti-pilling polar fleece fabric:
3.1 Classified by production process:
Polar fleece is divided into 2 sides brushed and 1 side anti-pilling, 2 sides brushed and 2 sides anti-pilling. 1 side brushed and 1 sides antipilling and so on.
Generally, polar fleece factories also produce double-sided fleece, single-sided fleece, sheared fleece, soft cotton fleece, ironing fabrics, etc., and can also provide light-set grey fabrics.
3.2 Classified by source of raw materials:
Poly Spun ( melange polar fleece)
Long fiber (low stretch yarn DTY, bright yarn FDY).
In general, poly spun fiber polar fleece is more expensive than long fiber polar fleece, and long fiber polar fleece is mostly used for making blankets. While poly spun fiber polar fleece used for apparel like tracksuit, hoodie, sweater, etc.
3.3 Classified by style:
- One brushed and on side anti-pilling
- Two sides brushed and two sides anti-pilling
- Two sides brushed and one side anti-pilling
- One side brushed and one side anti-pilling
3.4 Classified by species:
- Single color
- Color bars
- Drawing squares
3.5 Polar fleece is divided into plain dyed and printed.
Plain dyed (monochrome) polar fleece can be divided into striped polar fleece, embossed polar fleece, and jacquard fleece according to personal requirements.
Drop-needle polar fleece
embossed polar fleece
Jacquard polar fleece (jacquard polar fleece)
According to the different printing paddles, the printed polar fleece has more than 200 varieties of colors such as penetration printing, rubber paddle printing, and transfer printing color strips. This fabric has novel and unique patterns, colorful colors, natural and smooth pattern, and is favored by people from all walks of life.

3.6 What is bonded polar feece?
Polar fleece fabric can also be bonded with all fabrics, and used in the production of cold-resistant clothing, which can make the cold-resistant effect better.
The common ones are the composite of polar fleece and denim, the composite of polar fleece and lamb fleece, the composite of polar fleece and mesh cloth with a waterproof and breathable membrane in the middle, and so on.
The composite technology of polar fleece can not only be used in clothing, but also widely used in other fabric crafts. The composite technology combines the same two quality or different quality polar fleece composite processing together, which can be used for the production of blankets. Polar fleece feels soft, and the bedding made after processing gives people a warm and comfortable feeling.

4. What is the application of anti-pilling polar fleece fabric?
Uses: As a kind of fabric, polar fleece is widely used in garment making and other fabric crafts. Polar fleece is mainly used to make clothes lining (generally choose full polyester 150D96F polar fleece, “D” thickness, “F” number). It can also be used for bedding, carpets, coats, jackets, vests , Windbreakers, clothing logos, gloves, scarves, hats, pillows, cushions, shoes and toys.
5. The Production principle and technology of anti-pilling polar fleece fabric
The principle of polar fleece is to use polyester to rub and fluff, bend and twist due to static electricity, and form small balls. The polyester fiber itself has high strength and the fiber is not easy to break, so the formed small balls will not fall off on the surface of the fabric. The ball forms the unique style of polar fleece. Because many fibers are entangled with each other, it locks a lot of air in the middle and slows down the convection with the outside air. It is an ideal warm fabric.
The process flow is as follows:
Weaving machine → adjusting machine → cloth dropping → dyeing factory distribution → cloth arrangement → sewing head → degreasing and dyeing → tank adding fluffing agent → dehydration → drying → vertical slitting → brushing → combing → shearing → polarizing → Chengding → Rolling → Packaging.
The dyeing and finishing process of polar fleece has four more processes than brushing, combing, cutting and shaking compared to lint-free fabrics. 
The bristles are the single fibers of the polyester yarn (silk) that are broken and pulled out to form a thick layer of fluff on the cloth surface.
Combing is to comb the fluff and stand upright on the cloth surface.
Shearing is based on the style of the fabric surface to be formed in the final product, including the size of the polar particles, the thickness of the fabric surface, cutting down the fluff of different lengths, and cutting off the excess fluff to obtain the desired height.
The fleece is set according to the style of the cloth surface by adding steam to the polarizer tube and the time of the polarizer, so that the fluff layer of the cloth surface is contracted by the high temperature of the steam in the polarizer tube, entangled with each other, and granulated.
6. Frequently Asked Questions of anti-pilling polar fleece fabric: Frequently Asked Questions of anti-pilling polar fleece fabric
6.1 How does polar fleece reduce dust absorption?
Polar fleece can absorb dust because its own fibers are electrostatically charged, and the static electricity has an adsorption effect, which will bring dust to the fabric or clothes. But now you can add antistatic additives or introduce good hygroscopic fibers to reduce static electricity. Consumers find that polar fleece is easy to generate static electricity and can be improved by adding clothes softener. It contains cationic surfactants to neutralize the static electricity on the fleece fibers.
6.2 How to distinguish the quality of polar fleece?
Most long fiber polar fleece is used to make blankets, and the price of short fiber polar fleece is slightly higher than that of long fiber polar fleece.
Staple fiber polar fleece is generally woven from 32S polyester yarn, among which hemp gray polar fleece is also a staple fiber polar fleece.
Long-fiber polar fleece is generally woven from polyester filaments, and can be woven from full polyester 150D96F, 150D48F, 150D144F, 150D288F, 75D72F, 75D144F, 100D144F, 100D288F, etc. Long-fiber polar fleece can be divided into low-stretch silk polar fleece (DTY) and shiny silk (FDY).
In general, the higher the F value, the better the feel of the fabric, and the higher the price of fleece. For example, 100D144F, 150D144F and other polar fleece are already ultra-fine fleece.
6.3 Does the polar fleece have pure cotton? Can pure cotton blankets be made?
All-cotton polar fleece is available in China, but very few, and it is technically difficult to check, especially when pilling.
6.4 What is the difference between composite polar fleece and double-sided polar fleece?
The composite polar fleece is made of two kinds of the same quality or different polar fleece through the laminating machine processing, and then stick together.
Double-sided polar fleece is a double-sided polar fleece treated by pilling.
The price is generally relatively higher for composite polar fleece.
Generally, blankets have more composite polar fleece, but some customers need two kinds of polar fleece of the same quality to be sewn together. There is no need to composite, but it is not very convenient to wash. In addition, there are more polar fleece filaments for blankets.
