Polar fleece (also known as Yangli fleece) is a kind of knitted fabric. It is a small ingot knitting structure, that is, the ground tissue is fed and woven together with the terry yarn, and the ground tissue plays the role of fixing the terry yarn. After weaving, the grey fabric is dyed first and then processed by various complex finishing processes such as drawing, carding, shearing, shaking, etc. It is the first choice for winter protection.
The polar fleece was invented by Malden Mills in the United States, and its trade name is Polar Fleece. At that time, when polar fleece could only be produced in the United States by MALDEN MILLS, the price of such fabrics was relatively high. In the mid-1990s, polar fleece was introduced from Taiwan to Quanzhou, Fujian. Later also started producing polar fleece in Zhejiang, Changshu, Wuxi, and Changzhou areas. With the rapid development and growth of polar fleece in China, the price has also dropped rapidly, becoming a civilian price.
The advantages of fleece:
●The front side of the fabric is brushed, the fleece is fluffy and dense, and it is not easy to lose lint and pilling.
●The effect of keeping warm is good.
●The polar fleece can also be compounded with all fabrics to make the effect of keeping out the cold better.
Disadvantages of fleece:
There are also some problems that need to be paid attention to. Generally, polar fleece is more common: horizontal strips (loom or yarn), shearing machine knife marks or straight strips, indentations caused by excessive stacking, holes (Brushing machine), left and right yin and yang hair (caused by spreading rollers), color stains (dyeing), water stains (condensed water from the shaker steam) and so on.
The production principle and technological process of polar fleece:
The principle of polar fleece is to use polyester rubbing and fluffing. Due to static electricity, it is bent and wound into small balls. The polyester fiber itself has high strength and the fiber is not easy to break, so the formed balls do not fall off on the surface of the fabric. The small balls form the unique style of fleece. Because many fibers are intertwined with each other, many airs in the middle is locked, and the convection with the outside air is slowed down. It is an ideal warm fabric.
The general process of polar fleece is as follows:
Weaving upper machine ➩ Adjusting machine ➩ Lower fabric ➩ Dyeing factory distribution ➩ Fabric arrangement ➩ Seam end ➩ Degreasing dyeing ➩ Cylinder raising agent ➩ Dewatering ➩ Drying ➩ Vertical slitting ➩ Bristle ➩ Carding ➩ Shearing ➩ Shaker ➩ Forming ➩ Rolling ➩ Packaging.
The dyeing and finishing process of polar fleece has more brushing, combing, shearing, and shaking processes than lint-free fabrics.
△The brush is to break and pull out the single fiber of polyester yarn (silk), forming a thick layer of fluff on the cloth surface.
The chemical composition of lamb fleece is 70% polyester and 30% nitrile. It is produced using high-speed warp knitting machines and is widely used in home textiles, clothing, and toys. Sheep velvet itself is not a normative term, it is the usual name of merchants. The reason why it is called velvet is that it is artificial velvet, so it is called lamb velvet, not lamb wool. Lamb fleece is not as expensive as lamb wool, but it has a good thermal effect, no less than lamb wool. Therefore, it is widely used in the clothing industry.
There is a difference between lamb's wool and lamb's wool. Lamb's wool is really superfine wool, selected long wool; lamb's wool is actually artificial wool, so it is called lamb's wool.
Features of lamb velvet:
1. The appearance is light and clean, with good air permeability and drape
2. Soft texture, light and transparent, smooth and elastic
3. It is very comfortable to wear on the body, very elegant
4. After high-temperature shrinkage treatment, it is not easy to deform and wrinkle
5. Good physical properties, high fiber strength, wear-resistant and durable
The difference between polar fleece and lamb fleece:
1. Look at the ingredients
Sheep velvet, lamb velvet itself is not a normative term, it is the usual name of merchants, which belongs to imitation cashmere. The general composition is 100% polyester or blended with acrylic. Or wool and chemical fiber blends.
Polar fleece, also known as Yang Li fleece, is a kind of knitted fabric. and other complex processes.
2. Touch the feel
Lamb velvet is soft, smooth and delicate, and elastic. High fiber strength, good physical properties, not only wear-resistant but also durable. And after high-temperature shrinkage treatment, it is not easy to deform and wrinkle.
The fleece is fluffy and dense, and it is not easy to lose hair and pilling. Its ingredients are generally all-polyester and soft to the touch.
3. Look at the fluff
The fluff of lamb fleece is fine and long, and some of the fluff is lumpy, and the weaving texture is not very visible, while the fluff of polar fleece is short, the surface is flat, and the weaving texture is clear.
