Problems solved by technology

[0003] The development of silicone has gone through three stages. The first generation is methyl silicone oil emulsion, which emulsifies polymethyl silicone oil to form a non-ionic type. It is mainly used in the smoothing component of yarn lubrication or raising agent, but due to the hard hand feeling , needs to be compounded with other products such as softener film or soft oil; the second generation is D4 silicone oil emulsion polymerization, also known as hydroxyl emulsion, which has good smoothness, but still has ...

Abstract

The invention discloses a fabric softening agent. The fabric softening agent comprises the following raw materials: alpha, omega-dihydroxy polydimethyl siloxane, unsaturated glycidyl ether, Si-H-containing polydimethyl siloxane oligomer, octamethyl cyclotetrasiloxane, coupling agents, emulsifiers, an acid catalyst and water, wherein a preparation method for Si-H-containing polydimethyl siloxane oligomer comprises the following steps: mixing 20-40 parts in weight of trimethoxy silane and 1-2 parts in weight of trifluoromethanesulfonic acid, dropwise adding 10-20 parts in weight of deionized water within 20-30 min while stirring at room temperature, heating reflux for 1-2 h, cooling to room temperature, adding toluene and water for cleaning, and performing reduced pressure distillation at 60-80 DEG C to obtain the Si-H-containing polydimethyl siloxane oligomer. The fabric softening agent provided by the invention is excellent in hand feeling, resistant to washing, low in yellowing, high in hydrophilic effect, resistant to high temperature and high in shearing, and can be applied to a cheese high-shearing process and the like.

Description

technical field [0001] The invention relates to the field of textile auxiliaries. More particularly, the present invention relates to a fabric softener. Background technique [0002] Among textile printing and dyeing auxiliaries, softeners are a large category of finishing agents, and their main function is to meet the requirements of different handles and styles of various textiles. Textile softener products are mainly divided into two categories: one is the non-silicon aliphatic type: mainly cationic type, there are also nonionic type, anionic type and anion and zwitterionic type. The dosage forms are: emulsion, thick paste, High-concentration softening oil and waxy soft flakes and soft beads, etc.; the second is the type of silicone: silicone softener is the most widely used softener variety in the textile industry at present, and it is also used in textile printing and dyeing to improve product quality and increase product added value. After years of development, it ha...
