Sanding process
Sanding is a post-treatment process. It is the friction of the cloth through the sanding machine and the emery skin to form a layer with a short pile layer on the surface of the fabric, which not only retains the original characteristics but also gives the fabric a new style, which increases the warmth Sex and softness, thick and soft, rich in texture, non-fading, and the color will last forever. It is suitable for winter warm products and personal use products.
The whole process is like this: first padding the raising agent, drying and stenting, and then sanding and finishing on a special sanding machine.
After the general grey cloth is pre-treated (desizing, smelting, bleaching, mercerizing, etc.), the cloth surface is very smooth and smooth, and the sanding is rubbed on the cloth surface with a roller covered with sand (according to the different bags of the cloth). Put on different numbers of sand skins, and then put the cloth surface on the sanding roller of the sanding machine at a high speed, give a certain tension, and slowly pass through, after the friction of the six sanding rollers on the cloth surface, the cloth surface will have Thick fluff. Thereby changing the structural properties of the surface of the fabric, forming a layer of fluffy feel, just like the skin of a peach.
Therefore, the sanding finishing is also called imitation peach skin finishing, and the sanding cloth is also called peach skin flannel or sanding flannel. According to the strength requirements, sanding is divided into deep sanding, medium sanding or shallow sanding.
Features of brushed fabric
As a fabric process, sanding enhances the softness and warmth retention of the fabric while giving the fabric a new style. It is better than non-brushed fabrics in terms of hand feel, comfort and appearance, and is especially suitable for use in winter. .
Advantages of cotton brushed fabric
If you look at the process of sanding alone, it seems that sanding and finishing can't support his added value, so adding a sanding is so much more expensive? In fact, it is not the case, there are some other things in it.
The cotton brushed fabric feels thicker and softer. The home textile fabric must be brushed and finished. It is necessary to pay attention to certain choices in the gray fabric. The fabric warp and weft are too dense, the organization is too sparse, the fabric is too thin, and the viscosity is too tight. Not conducive to sanding and finishing. The fabric is too thin, the damage is too large, and the sanding is easy to break. If the twist is too large, the yarn is harder, and the structure is too dense and it is not easy to fluff. Brushed fabrics are generally medium-thick fabrics, and they feel relatively soft. Therefore, brushed fabrics are more expensive than ordinary fabrics. The most common cotton fabrics in the market are 40s, and many of the brushed fabrics are made of 32x21s fabrics, which will feel much thicker at first touch. It is warm to the touch and has no icy feeling. The brushing changes the physical style of the fabric. A layer of short, dense and fine fluff is directly formed on the surface of the fabric, so it has the wool-like warmth of the fluffy tissue and has a good It's close-fitting, it is not cool to drill in winter, it is very suitable for winter use. It is soft and non-irritating. After the surface of the sanded fabric is rubbed and raised, the rigidity of the fiber surface becomes weak, and there is no irritation and no itching sensation when it touches the skin. It is suitable for close-to-body sleeping. The style is unique, the surface of the polished fabric has a layer of fine and even fluff. The reflection of light is also a diffuse reflection phenomenon in the visual sense. It will be relatively softer in the visual sense. The over-exposure of each pattern is more natural. , It looks more delicate and warm.
