Softener flake is an important finishing process in printing and dyeing. It is also a chemical substance that can change the static and dynamic friction coefficient of the fiber. So what is the effect of softer flake on textiles? Here is a brief introduction.
In the textile processing process, after many treatments, the fabric and the machine will directly rub against, easily damage and wipe the fabric and fiber, making the fabric and fiber feel rough, the general synthetic fiber feels worse, especially the microfiber fabric.The above is an introduction to the effect of softer flake on textiles.

About Acrylic Resins
Acrylic resins feature excellent transparency and durability, and are used in a broad range of applications from consumer items like lenses to industrial products like molding materials, coatings and adhesives. In addition, acrylic resins are also used in other areas, such as binders for paper/fiber processing, PC screens, display windows for cellular phones and light guide panels for liquid crystal display (LCD) backlights.
Due to their excellent durability and weatherability as coating materials, acrylic resins are used extensively in applications such as automotive, architectural and plastic coatings.
Acrylic resins have the below general characteristics.? Weather resistance? Transparency? Heat resistance? Water resistance

WHAT IS A DEGREASER?
A degreaser is a cleaner designed to remove grease, oils, cutting fluids, corrosion inhibitors, handling soils, fingerprints, and other contamination common in assembly, stamping and other metal fabrication in refineries, motor repair shops, airplane hangars, and factories, etc.. Degreasers go by a number of different names including precision cleaner, maintenance cleaner, as well as several specific for automotive repair such as carb cleaner or brake cleaner.
The objective for a degreaser is to remove the offending soil quickly, avoiding as much wiping and scrubbing as possible. Degreasing solvents are commonly packaged as an aerosol for convenience. Aerosols have the added advantage of providing a forceful spray that creates agitation and which penetrate small crevices.
Water-based degreasers are common in a trigger sprayer, or in gallon or drum containers for immersion or batch system cleaning.
Specialized equipment like ultrasonic or vapor degreasers are available for more automated cleaning. These processes are repeatable, so better suited for more critical cleaning applications, like aerospace or medical appliance maintenance.
Techspray offers a large selection of degreasers and maintenance cleaners under the G3?, E-LINE?, PWR-4?, and Precision-V brands, which range from economical heavy-industry cleaners to high precision solvents for sensitive components.
WHY DO I NEED A DEGREASER?
Dust, dirt, grease, and oxidation contamination can cause corrosion, slipping hazards, overheating, increase electrical resistance in contact areas, and many other issues. Degreasing may be required to prep for down-stream processes like painting or plating.
Cleaner Degreasers can clean oil, grease, oxides and handling contamination from equipment and assemblies that include:
-
Metal and fiber optic cable splices
-
Motors and transformers
-
Programmable Logic Controllers (PLCs)
-
Pneumatic and hydraulic assemblies
-
Electronics and electrical equipment
-
Meters/measurement devices
Industrial-strength degreasers are needed to remove grease, tar, asphalt, oil, and grime in these kinds of applications:
-
Clutches, armatures, generators, and compressors
-
Electrical motors and equipment
-
Bearings, chains, cables, pulleys and gear drives
-
Brakes, springs, and flywheels
WHAT IS THE DIFFERENCE BETWEEN A DEGREASER AND A CONTACT CLEANER?
Degreasers are intended to remove oil, grease, oxides and handling contamination from equipment and assemblies, while a contact cleaner does the same thing specifically for electrical contacts.
A contact cleaner (also called electrical cleaner, switch cleaner, electrical contact cleaner, and (specific for automotive repair) battery terminal cleaner removes contamination from electrical contacts, the conductive surfaces of connectors, switches and other electrical and electronic components with moving surface contacts.
WHAT DO I LOOK FOR WHEN SELECTING A DEGREASER?
There are several factors that can have a big impact on performance and safety in choosing the proper degreaser for a given application in an environment:
Flammability – Degreasers often contain very flammable alcohols and hydrocarbon solvents. They can be cheap and effective, but can be dangerous without proper ventilation, or around open flames, sparks (e.g. from welding), or hot surfaces. Nonflammable degreasers avoid these safety issues but are generally more expensive. In addition, some nonflammable cleaners can be very toxic, containing hazardous solvents like Perchloroethylene, trichloroethylene or n-propyl bromide. High flashpoint (often called “high flash”) solvents have vapors that are less likely to combust in normal ambient temperatures (say below 140°F/60°C).
Dielectric strength – If you plan to work on powered equipment, or need to switch it on before the solvent has flashed off, consider a degreaser with a high dielectric strength. Make sure you know the amperage and voltage of the circuits you are trying to clean before spraying anything onto the circuits, and evaluate the suitability of any cleaner in your application. Dielectric strength is the maximum electric field that the material can withstand before its insulating properties break down. The lower the dielectric strength, the more likely it will breakdown and allow electricity to flow through and short out.
Plastic / rubber compatibility – Care needs to be taken when cleaning plastic or components, rubber gaskets and seals. If the degreaser is incompatible with the plastic, it can craze (create small cracks), embrittle, or soften the material. Rubber seals may swell, shrink, or dissolve. A new degreaser should always be tested before being used broadly.
Toxicity – N-Propyl Bromide (nPB), Trichloroethylene (TCE) and Perchloroethylene (Perc) are highly toxic chemicals commonly used in degreasers to provide cleaning performance in a nonflammable formula. There are documented court cases where workers suffered major health effects when exposed to high levels of these chemicals. Workers reported headaches, dizziness, and even loss of full body control. There are also possible links to reproductive problems and cancer. All of this has caused maintenance facilities to reconsider their solvent choices, especially with manual cleaning when exposure tends to be higher.
Environmental issues – Volatile organic compounds (VOCs), solvents that add to smog, or solvents with high global warming potential (GWP) have been a focus of regulators. Some state (e.g. CARB, the California Air Review Board), municipal, and even industry-specific regulations restrict the use of high VOC or high GWP materials.
