twenty two. How to choose amino silicone oil for different fabrics?
Answer Under normal circumstances, according to conventional requirements, the selection of amino silicone oil for different fabrics is as follows.
① Pure cotton and blended chemical fiber fabrics, knitted fabrics and woven fabrics, mainly have a soft feel. You can mainly choose amino silicone oil with an ammonia value of 0.6.
②Pure polyester fabric, mainly with smooth feel, you can choose amino silicone oil with an ammonia value of 0.3.
③ Silk knitted fabrics and woven fabrics mainly have a smooth feel and have high requirements for finish. Amino silicone oil with an ammonia value of 0.3 is mainly selected, and a smoothing agent is added to increase the finish.
④ Wool and its blended chemical fiber fabrics require a soft, smooth, elastic and comprehensive feel with small color changes. You can choose amino silicone oil compound products with 0.6 ammonia value and 0.3 ammonia value. Some varieties can be compounded with smoothing agents to increase elasticity and gloss.
⑤Cashmere sweaters and cashmere fabrics have a higher overall feel than wool fabrics, so you can choose high-concentration compound products.
⑥ Nylon socks, mainly with smooth feel, choose high elastic amino silicone oil.
⑦ Polyacrylonitrile fiber raschel blankets, polyacrylonitrile fiber and blended chemical fiber fabric yarns are mainly soft and have high elasticity requirements. You can choose amino silicone oil with an ammonia value of 0.6 to take into account elasticity requirements.
⑧ Linen fabrics (flax, ramie) are mainly smooth, and amino silicone oil with an ammonia value of 0.3 is mainly selected.
⑨ Rayon and rayon are mainly soft to the touch. You can choose amino silicone oil with an ammonia value of 0.6.
⑩Polyester alkali-reducing fabrics, mainly to improve the hydrophilicity of the fabric, can choose polyether modified silicone oil (CGF), which is composed of methyl hydrogenated silicone oil and polyethylene glycol and polyethylene glycol with unsaturated bonds at the end. It is made by hydrosilation reaction of polyethers such as propylene glycol. However, the softness is poor. The new polyether modified silicone oil introduces reactive epoxy groups into the silicone chain, which improves the feel and durability of the fabric.
