Fibers are elongated substances of a certain length and fineness, usually consisting of many molecules. Fibers can be divided into two categories: natural fibers and chemical fibers.
Natural Fibres: Natural fibers are fibers extracted from plants, animals, or minerals, and common natural fibers include cotton, silk, and wool. Natural fibers have good breathability, moisture absorption, and comfort, and are widely used in textiles, garments, home furnishings, and other fields.
Chemical fibers: Chemical fibers are fibers synthesized from raw materials through chemical methods, mainly including polyester fibers, nylon fibers, acrylic fibers, adenosine fibers, and so on. Chemical fibers have good strength, abrasion resistance, and durability, and are widely used in textiles, construction, automotive, medical, and other fields.
Chemical fibers have a wide range of applications, but there are still difficulties in their production and processing.
Raw material treatment: The manufacture of chemical fibers usually requires pre-treatment of raw materials, including polymerization, spinning, and other processes. The treatment of raw materials has an important impact on the quality and performance of the final fiber, so the composition, purity, and treatment conditions of the raw materials need to be controlled.
Spinning process: The spinning of chemical fibers is to melt the polymer and then stretch it into silk through the spinneret orifice. During the spinning process, parameters such as temperature, pressure, and speed need to be controlled to ensure the uniformity and strength of the fibers.
Stretching and shaping: Chemical fibers need to be stretched and shaped after spinning to improve their strength and dimensional stability. This process requires control of temperature, humidity, stretching speed, and other factors to obtain the desired fiber properties.
These are some of the difficulties that exist in the production and processing of chemical fibers. With the progress of science and technology and the improvement of processes, these difficulties have been gradually solved, and the production technology of chemical fiber has been continuously upgraded.
Many manufacturers also improve the quality of products by improving the performance of raw materials. Chemical fiber production generally uses raw materials such as nylon fiber, acrylic fiber, adenosine fiber, and polyester fiber, of which polyester fiber is a very common chemical fiber, and the commonly used raw material is polyethylene terephthalate (PET). Polyester fiber has good strength, abrasion resistance, and wrinkle resistance, and is widely used in textiles, furniture, car interiors, carpets, and other fields. The addition of SILIKE silicone masterbatch can make PET fiber have better processing performance and reduce the defective rate of the product.

SILIKE Silicone Masterbatch LYSI-408 is a pelletized formulation with 30% ultra-high molecular weight siloxane polymer dispersed in polyester (PET ). It is widely used as an efficient additive for PET-compatible resin systems to improve the processing properties and surface quality, such as better resin flow ability, mold filling & release, less extruder torque, lower coefficient of friction, and greater mar and abrasion resistance.
Typical properties of SILIKE Silicone Masterbatch LYSI-408
(1) Improve processing properties including better flow ability, reduced extrusion die drool, less extruder torque, better molding filling & release
(2) Improve surface quality like surface slip, lower Coefficient of friction
(3) Greater abrasion & scratch resistance
(4) Faster throughput, reduce product defect rate.
(5) Enhance stability compared with traditional processing aids or lubricants
Areas of application for SILIKE Silicone Masterbatch LYSI-408
(1) PET fibers
(2) PET & BOPET film
(3) PET bottle
(5) Engineering plastics
(6) Other PET compatible systems
SILIKE LYSI series silicone masterbatch may be processed in the same way as the resin carrier on which they are based. It can be used in classical melt blending processes like Single /Twin screw extruders, and injection molding.
Different applications require different dosages, so it is recommended that you contact SILIKE first if you have a need.
