Grinding
Refers to the use of roller or metal roller friction on the cloth surface;
Different fabrics are combined using different numbers of sand skins to achieve the desired sanding effect.
The general principle is to use high mesh counts for high count yarns and low count counts for low count yarns.
Roller rolls are used for forward rotation and reverse rotation. Generally, only odd-numbered skin rollers are used.
The factors affecting the sanding effect are:
Grinding roller rotation speed, vehicle speed, cloth body moisture content, coating angle, tension, etc.
Fleece
It is inserted into the inside of the yarn with an angled wire looper, hooking the fiber to form hairiness;
Laying is a meaning, a different saying.
Different fabrics use different steel needles, which have round heads and pointed heads. Generally speaking, the cotton heads are pointed and the wool heads are round;
The influencing factors are:
Speed, speed of cloth roller, number of cloth rollers, moisture content, tension, clothing density, bending angle of steel needle, twist of yarn, auxiliaries used for pretreatment, etc.
Bristles
It uses a bristle roller like a brush to sweep over the cloth surface;
Different fabrics and treatments use different bristle rolls, bristle brushes, wire brushes, carbon silk brushes, and ceramic fiber brushes.
Simple processing using bristle brushes, such as brushing cloth before singeing; wire brushes are generally fabrics that require high nap, such as knitted fleece; carbon wire brushes are used for high-grade cotton fabrics, requiring fine surface treatment; more demanding processing Fine use of ceramic fibers.
Influencing factors:
Number of brush rollers, rotational speed, stiffness of brush filaments, fineness of brush filaments, density of brush filaments, etc.
Supplement: The concept of grasping and pulling hairs is the same process. The equipment used is a brushing machine. The needles are used to pull out the microfibers in the fabric yarns to form a surface fluff effect. The specific products are flannel, Silver yam and the like, the nap process is also called "raising";
Grinding
The equipment used in the process is a sanding machine, which uses sand, carbon, ceramics and other rollers to grind the microfibres in the fabric yarns to form a fluff effect on the surface. Compared to the products that are pulled, the rough fluff is short and dense. Felt is very delicate, the specific products are grinded yarn card, napped poplin, jeanette and the like, and some of the brushed products look hairy is not obvious, but the hand feel has been greatly improved;
Bristles
Mainly the special process of corduroy, because the corduroy's fluff is cut off the weft of the face tissue, the yarn is broken through the bristles and form a cohesive velvet, the equipment used is a bristle machine, generally equipped with 8-10 hard brushes And 6-8 track soft brush, thick corduroy still need to go through after the bristles, after the brush machine in addition to hard, soft brush is also equipped with a wax plate, in the bristles process at the same time to the villi wax, is a corduroy velvet Gloss, so after the brush machine is also called waxing machine.
