The abrasive qualities of man-made fibres, particularly nylon and polyester, as well as the corrosive characteristics of additives such as fibre finishes and lubricants combine together to deteriorate yarn contact surfaces. The result is costly downtime for replacement of machinery parts, or even worse, the degrading of yarn quality. Metal/Thermal Spray coatings help textile mills regarding maintaining various plant equipment to keep away degrading factors like corrosion, wear, erosion and abrasion.
MSSA supply the Textile Industry with solutions for coating protection from wear and tear on equipment including, but not limited to: draw rolls, separator rolls, finish applicator rolls, take-up rolls, thread guides, feed separators, pins, rolls, guide bars, sleeves, snick pins, heater plates, weaving shuttles, tension washers and heater plates.
Both metals and ceramics can be applied dependent upon the operational characteristics under which the component is being subjected. For instance, Goddet rolls used for guiding and drawing of the yarn are coated with Chrome Oxide using Atmospheric Plasma Spray or they can also be coated by using Rokide® C rods or Flexicord®. The Chrome Oxide gives good resistance to mechanical friction and good abrasion resistance.
Textile Equipment Coatings – Saint-Gobain Coating Solutions
Industry: Textile Machinery – thread guides, feed separators, pins, rolls, guide bars, sleeves and more.
Principle of the Process: The textile industry is using parts such as guides, rolls, separators to guide the thread during weaving and winding operations. The thread is fed at very high speed in order to ensure sufficient efficiency and profitability of the textile machines.
Problem: The machines used in textile industry are exposed to extreme wear due to the fast feeding by kilometres of textile thread across the guides. The surface of the guides must remain very smooth, without grooves, scratches and pinholes to avoid that the thread becomes fluffy.
Service Conditions:
- High friction of the thread sliding at very high speed.
- Risk of electrical static discharge due to the friction effect.
Coating Solution: Ti-Tex Flexicord® coating solution (see also Ti-Elite).
Ti-Tex Coating
Benefits of the Ti-Tex Flexicord®:
- The Ti-Tex is manufactured in a proprietary process which provides a unique and very fine distribution of Alumina and Titania alloy down to crystallite size.
- Ti-Tex produces coatings which are dense (4% porosity), hard (950 Hv300) and smooth (3 to 4µm as sprayed).
- Ti-Tex resists to wear caused by friction of the textile wire.
- After surface finishing Ti-Tex is very homogeneous and provides a very fine surface quality. Tumbling or super-finishing are recommended, if a smoother finish of a Ti-Tex coating on very small parts or on parts with unusual contours is required.
- The Ti-Tex structure is ideal for textile applications. Ti-Tex ensures 10 to 15% higher lifetime, with a better surface finish.
- Ti-Tex is sprayed with a flame wire gun that can also spray ROKIDE C rods.
- The spray pattern is narrow, coatings on narrow parts is thus possible (grove, capstan, pin, textile wire guide).
