I. OverviewAfter the fabric is pre-treated and a series of dyeing and finishing additions, the natural oil and wax are removed, which tends to reduce its original smoothness and make the hand feel rough. In addition, some fabrics need to undergo high temperature treatment, such as resin finishing, heat setting of synthetic fiber, steaming and puffing of acrylic fiber, and pigment printing, etc., which will also make the fabric feel rough and hard.Most synthetic fabrics and pure wool and cotton v ...

Wetting agent A substance that can make solid materials more easily wetted by water. By reducing its surface tension or interfacial tension, the water can spread on the surface of the solid material or penetrate the surface, thereby wetting the solid material.Wetting agent is a surface active agent that can make solid materials more easily wetted by water by reducing its surface energy.Such as sulfonated oils, soaps, pull open powder BX, etc., soy lecithin, mercaptans, hydrazides and mercaptan a ...

The basic properties of silicone adhesives Organic silicone adhesives have unique heat and low temperature resistance, good electrical properties and weather resistance, chemical stability, hydrophobic and moisture resistance, oxidation resistance, workability, sealability, breathability In a wide temperature range, the electrical properties change very little, and the dielectric loss is low. It can be made into high-grade sealing material, mainly used for sealing bonding of window glass and gla ...

Among the wide variety of softeners, silicone additives have attracted more and more attention due to their unique surface properties and excellent softening properties. Most domestic fabrics finished with silicone softeners are hydrophobic, which makes the wearer feel stuffy and difficult to wash. Many products often show demulsification and bleaching. The traditional hydrophilic polyether silicone oil has better hydrophilicity and water solubility, but its flexibility and finishing effect are ...

Polyurethane adhesive refers to an adhesive containing urethane groups (-NHCOO-) or isocyanate groups (-NCO) in the molecular chain. Polyurethane adhesives are divided into two categories: polyisocyanate and polyurethane. Polyisocyanate molecular chain contains isocyano group (-NCO) and carbamate group (-NH-COO-), so polyurethane adhesive shows a high degree of activity and polarity. It has excellent chemical adhesion with substrates containing active hydrogen, such as foam, plastic, wood, leath ...

Polydimethylsiloxane, (Polydimethylsiloxane), is a hydrophobic silicone material. It is used in various fields such as medicine, daily chemical products, food, construction, etc. Its derivatives have reached hundreds of kinds. The commonly used polysiloxanes are mainly: polydimethylsiloxane, cyclomethicone , Aminosiloxane, polymethylphenylsiloxane, polyether polysiloxane copolymer, etc. Among them, cyclomethicone is one of the commonly used polysiloxanes.Physical and chemical propertiesThe chemi ...

In the production of polyether modified silicone oil, various silicone surfactants with different properties can be obtained by modifying the number of silicone oil chain links or changing the ratio of polyether Eo and Po and changing the number of chain links and end groups. To meet the needs of a variety of industries. Good leveling, suitable for adding to a variety of resins (polyurethane resins, paint resins, plastic resins, etc.), which can well improve the intermolecular stress of these re ...

Silicone resin coatings are organic silicon resins or modified organic silicon resins as the main film-forming substances, which are elemental organic coatings, referred to as organic silicon coatings. Elemental organic coatings are the general term for coatings with elemental organic polymers as the main film-forming substances, including organic silicon, organic titanium, organic fluorine, organic aluminum, and organic zirconium coatings. Among them, the output of silicone resin coatings is th ...

In plastic compounding, a plastic additive that improves the interface performance of synthetic resins and inorganic fillers or reinforcing materials. Also known as surface modifier. It can reduce the viscosity of the synthetic resin melt in the plastic processing process, improve the dispersion of the filler to improve the processing performance, and then make the product obtain good surface quality and mechanical, thermal and electrical properties.The dosage is generally 0.5 to 2% of the fille ...
