The principle of polar fleece fabric 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.
Many fibers are entangled with each other, lock a lot of air in the middle, slow down the convection with the outside air, polar fleece is an ideal warm fabric. The following is the technological process and specific steps of the polar fleece fabric.
In the textile industry, polar fleece belongs to weft knitted fabrics. A simple way to distinguish knitted fabrics from woven fabrics is to zoom in on knitted fabrics, and the yarns tend to move in circles, while woven fabrics are horizontal and vertical.
The yarn will be divided into the ground yarn and the pile yarn and fed into the machine together. The ground yarn plays the role of fixing the pile yarn and is basically invisible. Get a piece of polar fleece, we can only see terry yarn.
The general process flow is as follows:
weaving upper machine-adjusting machine-bottom fabric-dyeing factory fabric-arranging-sewing head-degreasing and dyeing-vat with raising agent-dewatering-drying-sectioning-brushing-combing-shearing-polarizing-rolling-packaging.
The dyeing and finishing process of polar fleece has more processes of brushing, combing, cutting, and shaking than lint-free fabrics.
The bristles are the single fibers of the polyester yarn (silk) that are pulled out by the brush, forming a thick layer of fluff on the cloth surface.
(1) The woven fabric is put into a dyeing machine for high temperature and high pressure for dyeing. After dyeing, it is washed, dehydrated, and added with specific additives (softening agent, raising agent) to complete the "soft" process. The softness is for the next step-the bristles are smoother.
(2) Dry the fabric, start brushing (grabbing-pulling), use a brushing machine to pick up and loosen the fluffy yarn on the surface of the fabric.
(3) After the loose fluff yarn is combed with a carding machine, it is sent to the shearing machine to trim the fluff that has been combed just now with different lengths.
(4) Then, the fleece machine comes on the scene, and the fleece machine injects high-temperature steam to turn and knead the fabric so that the plush on the surface of the fabric is entangled and becomes granular. Finally, dry and shape and a piece of soft fleece fabric are ready.
Some inferior polar fleece fabrics will have horizontal stripes, indentation, dyeing, and watermarks caused by long stacking. We also need to pay attention when purchasing.
