Abstract

The invention discloses a softening agent applied to a linen fabric and a preparation method thereof. The softening agent is prepared from the following ingredients in parts by weight: 100 parts of modified polysiloxane, 32 to 48 parts of hydroxyl-terminated polymethyl hydrosiloxane, 21 to 33 parts of polydimethylsiloxane, 11 to 19 parts of an emulsifier, 9 to 15 parts of organic acid, 21 to 33 parts of chitosan and 8 to 15 parts of a surface active agent. After being treated by the softening agent disclosed by the invention, the linen fabric has soft hand feeling; furthermore, a wearing effect is obviously improved, the linen fabric can still keep good softness after being used for a long time and washed for many times, and the linen fabric is not prone to yellow.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to a softener for linen fabrics and a preparation method thereof. Background technique [0002] Linen fabric is a kind of natural cellulose fiber, which is the main raw material for hemp spinning, and is known as the "fiber queen". Linen fabric has the advantages of fast moisture absorption and moisture dissipation, good air permeability, and crisp wearing, and because of the nature of the fiber itself, it has natural excellent antibacterial, anti-mildew properties, good anti-static and anti-ultraviolet properties, so it has been widely favored by people. focus on. However, flax fiber also has some certainties. Because of its high crystallinity, high degree of orientation, and neat and compact arrangement of macromolecules, it has small elongation and poor elasticity. In addition, the shape and structure of flax fibers will change greatly after the flax fabric undergoes a variet...
