Brushed fabric is a kind of fabric with excellent warmth and comfort, which is very suitable for Autumn and winter season.
Some people regard sanding as a kind of fabric, and some people simply understand sanding as pure cotton. , that’s all wrong.
What is sanding?
Sanding is just a post-processing process. The friction between the cloth and the emery leather makes the surface of the pure cotton fabric have a layer of short velvet.
Printing process of brushed cloth
1. Unwinding purpose: Unwind the rolled gray fabric The rolls are placed on the spreader cart.
2. The purpose of sewing: sew the rolls of gray fabric together.
1. Sanding mechanism: Sanding uses emery leather coated on a high-speed running sanding roller on a sanding machine. It comes into close contact with the fabric and forms a fluffy layer on the surface of the fabric through mechanical friction. 2. Purpose of sanding: to give the fabric a new feel and high-end style, similar to the delicate, smooth and comfortable peach skin feel.
3. Factors affecting sanding: The speed of the sanding machine is affected by the weight of the fabric. The thicker the fabric, the slower the speed. Fabric tension affects the degree of sanding. Single and double-sided sanding is achieved by closing some of the sanding rollers.
1, scouring process: cloth feeding→scouring→washing→drying→dropping
2 , Purpose of scouring: to remove oil dirt and slurry during the textile weaving process.
1. Pre-styling purpose: fixed finished product size (fixed door width; fixed weight).
2. The benefits of pre-setting polyester fabrics: the size is stable and it is not easy to produce creases during printing; lowering the final setting temperature is helpful for the fastness of the finished product.
3. Polyester fabric presetting conditions: temperature 180-200℃, vehicle speed 93m/min. Tension: use needle plate in transverse direction and tension roller in longitudinal direction.
1. Principles of rotary screen printing: dark colors in the front, light colors in the back, fine lines in the front, and large areas of color in the After; purpose: to avoid dark colors overlapping light colors and to prevent the edges of patterns from blurring.
2. Rotary screen: mostly nickel screen. During printing, the color paste is printed onto the fabric from the patterned mesh.
3. Common defects of rotary screen printing: bottom exposure, bleeding, and color matching. Common reasons: incorrect flower alignment, blocking the net, causing the bottom to be exposed; dark slurry being too thin, causing bleeding; two colors matching to produce a third color.
1. Purpose of steaming after printing: to diffuse the disperse dye into the interior of the polyester fiber and fix it on the fiber, and develop color at high temperature . (Color fixation, color development) 2. Main influencing conditions: steaming temperature 190°C; steaming time: 4 minutes.
1. Purpose of washing: to remove the original printing paste and floating colors to reveal a clear pattern to ensure good color fastness.
2. Washing aid: insurance powder → restore and clean to remove floating color.
1. Softness purpose: to increase the softness of the brushed cloth and improve the feel.
2. Softening treatment: Add a certain amount of softener into the trough at the front of the finished product setting machine. Excessive dosage → reduced fabric strength and other problems.
1. Purpose of finished product shaping: finalize the size of the finished product.
2. Shaping conditions for finished sanded cloth products: temperature 180-200℃, vehicle speed 93m/min. Tension: use needle plate in transverse direction and tension roller in longitudinal direction.
Dyeing process of brushed cloth
1. Overflow dyeing machine: It consists of a normal pressure dye vat, a circulation pump, a feeding tank, a pipeline system, and a cloth guide roller in and out.
2. Working principle: There is a wheel inside to drive the cloth to rotate. When the cloth is dyed in the dye vat, the soaking time and dyeing effect of the cloth are controlled by controlling the running speed.
3. Overflow dyeing�Disadvantages: Each tank presents a color from light to dark depending on the distance from the feeding tank (for multi-tank overflow dyeing machines). 4. Overflow dyeing process conditions: liquor ratio 1:6. 2000m of sanded cloth per cylinder (about 442kg).
1, light color (ace dye)
2, medium light Color: (E-GL yellow, 3B red, 2BLN blue) Dyeing temperature 120℃, dyeing time 20min, other things remain unchanged.
3. Dark color: (S-2RFL brown, SE-2GFL ruby, ARO black, HGL blue) dyeing temperature 120℃, dyeing time 20min, other things remain unchanged.
4. Whitening process: dyeing temperature 120℃, dyeing time 20min, pH value of the cloth is 4.
1. Dehydration purpose: reduce the burden of subsequent drying.
2. Purpose of opening: open the door to facilitate subsequent work.
Opening requirements: The sanded side should be opened outwards to facilitate cleaning of cloth lint; the uniform side should be opened to facilitate the distinction between positive and negative.
Dyeing and printing of brushed cloth are carried out in one step
The customer requires a very soft feel
The gray fabric is dyed first and then printed.
Add scouring agent to the overflow dyeing vat to scouring the gray fabric, then wash it with water and then dye it. </p
