HLB value is bigger, and the hydrophily that represents is stronger, and HLB value is smaller, and to represent lipophile stronger.It both with the parent of surfactant Water lipophile is related, but with adsorptivity, emulsibility and the emulsion stabilization on the surface of surfactant (interface) tension, interface The basic performances such as property, dispersibility, dissolubility, soil release performance are related, also related with the application performance of surfactant.

Softening agent and fabric softening

Softening agent mainly has surfactant-based and high molecular polymerization species softening agent.Surfactant-based softening agent is tool The molecular structure for having long-chain hydrocarbon has the performance of self-emulsifying and adsorption, because long-chain hydrocarbon Molecular Adsorption is in fiber surface, Fabric friction coefficient can not only be reduced, but also fibrillation can be prevented, keeps fabric feeling soft and smooth；Its mechanism is to pass through C-C Singly-bound can be rotated in the case where keeping 109 ° 28 ' of bond angle in singly-bound, is made long-chain at the rolled state of random arrangement, is formed The flexibility of molecule, flexible Molecular Adsorption play lubricating action in fiber surface, thereby reduce fiber and fiber it Between kinematics and static friction coefficient.High molecular polymerization species softening agent is general not soluble in water since molecular weight is larger, with swelling, lotion Or the form of microemulsion exists.Wherein, organic silicon softening agent is because its Si-O-Si main chain is the helical form straight chain knot of easy flexing Structure can occur 360 ° and rotate freely, and rotate that required energy is almost nil, and the active force between polysiloxane molecule is than hydrocarbon Backbone much weaker so that polysiloxanes is lower than the hydrocarbon viscosity of same molecular weight, surface tension is small, film forming is strong； Its unique molecular structure enables its molecule is submissive to rotate freely, and not only reduces the interfibrous quiet, coefficient of kinetic friction, and its point Sub- intermolecular forces are small, can also substantially reduce the surface tension of fiber, are the current optimal materials of textile soft finishing agent.But It is to be easy to occur in system unstable and oil spill since the density ratio matrix liquid detergent density of the softening agent of organic silicon is low Phenomenon causes system to be layered.

Cationic compound softening agent at present it is most commonly used, mainly due to big multifilament in water carry negative electricity Lotus, cationic softener are easily absorbing on the fiber surface, and binding ability is stronger, energy high temperature resistant, wash resistant, through cation Soft result of the fabric after type softening agent arranges is best and plentiful smooth, has certain antistatic effect, energy to synthetic fibers Improve fabric wearability and tearing brute force, similarly partial cation polymer due to the anion surface active in matrix Agent acts on, and may be settled in system.

Softening agent assigns fabric " soft comfortable ", i.e. fabric softening.It is mainly reflected in three aspects：(1) finger It mutually slides, rub between fiber, flexibility is related with the dynamic friction factor of fiber and static friction factor；(2) fabric washing is rubbed with the hands Fabric is ground, flexibility is related with the surface tension of fiber；(3) hydrogen bond link causes yarn between the friction between fabric causes fiber Line fibrillation, flexibility are related with fibrillation.

Softening agent used herein is mainly cationic polymer softening agent and organosilicon oils softening agent.Herein for Cationic polymer softening agent reflects layered liquid crystal structural system and non-laminar liquid crystal by its sedimentary difference on the fabric Structural system embodies the composition with layered liquid crystal structure and contributes to cationic polymerization to the difference of fabric softness The deposition of the softening agent of object on the fabric and the improvement to fabric softening；Wherein softening agent deposits on the fabric uses wool cloth Decoration method obtains, and mechanism is negatively charged based on wool cloth, and cationic polymer softening agent can be adsorbed on the fabric, then be adopted Effect dyeing is carried out with the cationic softener on anionic dye and fabric, dyeing wool cloth and blank are tested by color difference meter The aberration of sample, the difference that cationic softener deposits in wool cloth in qualitative more different systems.It is soft for organosilicon oils Soft dose, mainly investigated by high-temperature stability, naked eyes or microscope it is microcosmic examine composition whether occur silicone oil softening agent floating Phenomenon, and then determine that layered liquid crystal structure contributes to its stable suspersion in the composition, improve the flexibility of fabric.
