The present invention discloses a skin-care anti-bacteria microcapsule finishing agent
and a preparation method and application thereof. The finishing agent includes an organic
silicon microcapsule, wherein a surface of the organic silicon microcapsule is modified by
using an organosilicon quaternary ammonium salt; and the organic silicon microcapsule is

so as to acquire the non-adhesion skin-care anti-bacteria microcapsule finishing agent. The
finishing agent is directly added into cellulose fiber fabric after-finish liquor when being
applied without adding any adhesion agent; a finished fabric has a long lasting anti-bacteria
property while having a lasting skin-care moisture-retention effect, and a hand feeling and a
style of the fabric are not influenced at all.
Description
The present invention belongs to the technical field of fabric finishing, and particularly
relates to a skin-care anti-bacteria microcapsule finishing agent and a preparation method and
application thereof.
Close-fitting fabrics are good skin-care health-care carriers, and various skin-care
heath-care products are loaded onto underclothes and fabrics by means of methods such as
spinning, coating and after-finish, thereby producing effects lastingly. Various health-care
fabrics are developed so as to improve the value of the fabrics. According to CN101418517A,
a quaternary ammonium salt and TEOS are taken as raw materials, anti-bacteria sol is
acquired under the action of a catalyst, but an anti-bacteria agent is only adsorbed into a gel
net by means of a physical effect, after washing is conducted 10 times, anti-bacteria rates to
escherichia coli and staphylococcus aureus are both less than 80%, and a washable effect is
not good. CN102704280A discloses VE microcapsule fabric finishing liquid with a skin-care
function for a human skin and a preparation method, polyurethane being selected as a wall
material, VE with a moistening and skin-care function being selected as a core material,
microcapsule emulsion being acquired by means of interfacial polymerization, an adhesion
agent being added during finishing, and a relative residual percentage of the VE of a fabric
being up to 80% or more after 10 times of washing.
In order to solve a bonding problem between the microcapsule and a fiber, adhesion
agents such as crylic acid and the polyurethane are often used. When a using amount of the
adhesion agent is less, no direct affinity exists between the microcapsule and the fiber, so the
microcapsule is prone to falling from the fabric under the action of friction or washing; but if
the using amount of the adhesion agent is increased only for pursuing adhesive force of the
microcapsule, a style of the fabric may be changed, a harsh hand feeling may be generated,
sweat permeability or even air permeability of the fabric may be lowered, resulting in an uncomfortable feeling during fabric using. In recent years, a fabric microcapsule finishing process without usage of the adhesion agent has also been disclosed. According to
CN104746350A, a microcapsule containing traditional Chinese medicine oil is prepared by
means of a complex coacervation method and added in the in situ polymerization process of
polyacrylate so as to acquire a polyacrylate adhesion adgent containing the traditional
Chinese medicine oil microcapsule, no other adhesion agents need to be added during
finishing, a washable and anti-bacteria property is provided for the fabric, but the nature of
the present invention is still to finish and arranged the microcapsule onto the fabric by means
of the adhesion agent. According to CN108424477A, p-cyclodextrin is modified by means of
a silane coupling agent KH550, then an anti-bacteria agent limonene is included to acquire a
limonene-KH550 modified j-cyclodextrin inclusion compound, and finally, the inclusion
compound, gelatin, Arabic gum, limonene and the like are made into a microcapsule. After
the p-cyclodextrin is modified by means of the silane coupling agent, a silicon hydroxyl may
enhance curing of the microcapsule and bonding between the microcapsule and the fiber so as
to enable the microcapsule to be more stable and not prone to falling. The microcapsule
formed by a natural wall material has good biocompatibility but poor mechanical property
and heat stability.
In order to overcome the defects in the prior art, the present invention provides a
non-adhesion skin-care anti-bacteria microcapsule finishing agent, wherein the finishing
agent is directly added into cellulose fiber fabric after-finish liquor when being applied
without adding any adhesion agent; a finished fabric has a long lasting anti-bacteria property
while having a lasting skin-care moisture-retention effect, and a hand feeling and a style of
the fabric are not influenced at all.
The skin-care anti-bacteria microcapsule finishing agent includes an organic silicon
microcapsule and a dispersing agent, wherein a surface of the organic silicon microcapsule is
modified by adopting an organosilicon quaternary ammonium salt;
the organic silicon microcapsule is formed with aloe extract and squalene as a core
material and tetraethoxysilane as a wall material.
Furthermore, a mass ratio of the aloe extract to the squalene is 1:1-1:2.
Furthermore, the organosilicon quaternary ammonium salt is (trimethoxy silicyl propyl)
octadecyl dimethyl ammonium chloride or (trimethoxy silicyl propyl) tetradecyl dimethyl
ammonium chloride.
A preparation method of the skin-care anti-bacteria microcapsule finishing agent
includes the following steps:
step 1, preparing core material emulsion: mixing a mixture of aloe extract and squalene
that is treated as an oil phase with an emulsifying agent, then adding the same into deionized
water, and dispersing the same to acquire O/W core material emulsion;
step 2, preparing a wall material solution: adding the TEOS into the deionized water,
adjusting pH to 2-3, and stirring, to acquire the wall material solution;
step 3, preparing an organic silicon microcapsule: dripping the wall material solution
into the O/W core material emulsion, adjusting pH to 8-10, stirring and filtering, and washing
and drying, to acquire a microcapsule solid; and
step 4, modifying by means of an organosilicon quaternary ammonium salt: mixing the
microcapsule solid and an acidic ethanol aqueous solution, adding the organosilicon
quaternary ammonium salt, adjusting pH to 8-10, stirring, then adding a dispersing agent,
continuing stirring, and standing, so as to acquire the finishing agent.
Furthermore, in the step 1, a mass ratio of the oil phase to the deionized water to the
emulsifying agent is 1:50:0.1-1:50:0.3. The emulsifying agent is one or more of Tween-series
or Span-series emulsifying agents.
Furthermore, in the step 2, a concentration of the TEOS is 10- 2 0wt.%, a stirring speed is
200-300 r/min, a stirring temperature is 20-30°C, and a sti rri ng ti me is 10-30 min.
Furthermore, in the step 3, a mass ratio of the O/W core material emulsion to the wall
material solution is 5-10:1, a dripping speed is 10-30 drop/min, a stirring speed is 400-500
r/min, a stirring temperature is 30-50°C, a stirring time is 3-5 h, and a drying temperature is
-80 0 C. Furthermore, in the step 4, pH of the acidic ethanol aqueous solution is 2-2.5, a
concentration of ethanol is 15-25% v/v, and the dispersing agent is one of hydroxymethyl
cellulose, sodium polyacrylate or sodium hexametaphosphate.
An application of the skin-care anti-bacteria microcapsule finishing agent in
anti-bacteria finishing of a cellulose fiber fabric is disclosed.
Furthermore, according to the application, specifically, the cellulose fiber fabric is
soaked in working liquid and then subjected to single-dipping-single-padding, a pickup is
%, then the fabric is baked at a temperature of 80-1OOC for 10 min, and the fabric is set at
a temperature of 120-150 0C for 40 s; and
the skin-care anti-bacteria microcapsule finishing agent in the working liquid has a
concentration of 50-100 g/L, and pH of 6-7.
Furthermore, the cellulose fiber fabric is a cotton fabric, a tencel fabric or a modal
fabric.
According to the present invention, the aloe extract and the squalene that have a
skin-care moisture-retention function are taken as the core material, the TEOS is taken as the
wall material, the microcapsule is prepared through a sol-gel method, modification is
conducted by means of the organosilicon quaternary ammonium salt, the acquired
microcapsule has good heat resistance, an active group of a surface of the microcapsule may
bond covalently to a hydroxyl of a cellulosic fiber, and no adhesion agent needs to be added
during finishing.
Aloe has a natural moisture retention effect, accelerates degradation of polymerized
fibrin in a skin, and may reduce loss of percutaneous moisture; and the squalene plays an
important role in sebum of a human body, promotes repair of aging cells and injured cells,
enhances a regeneration capacity of the skin, and has a natural skin care effect.
The TEOS may be controlled by adjusting pH of a system in a hydrolysis and
condensation process, firstly, the TEOS is partially hydrolyzed, at this time, a molecule
contains an alkoxyl and the hydroxyl at the same time, and when the TEOS is dripped into
the core material emulsion, along with increase of pH of an environment where the TEOS is,
the pre-hydrolyzed TEOS may be condensed at an O/W surface and be gradually deposited
on a surface of the core material to form the microcapsule.
The pH of the system is adjusted again so that remaining siloxane, which are not
hydrolyzed, on the microcapsule is completely hydrolyzed, then the pH of the system is
adjusted to be alkaline, the completely hydrolyzed microcapsule crosslinks with the added organosilicon quaternary ammonium salt to form a three-dimensional space net structure composed of Si-O-Si groups, heat stability of the microcapsule is further improved, and meanwhile, an anti-bacteria film is formed on the surface of the microcapsule.
The active group, which is unreacted after being hydrolyzed, of the microcapsule and
the hydroxyl of the cellulosic fiber fabric may form a firm covalent bond so as to provide a
lasting skin-care anti-bacteria function for the fabric, the finished fabric has the long lasting
anti-bacteria property while having the lasting skin-care moisture-retention effect, and the
hand feeling and the style of the fabric are not influenced at all.
The present invention has the beneficial effects that: 1, the aloe extract and the squalene
have the natural skin-care moisture-retention effect without any toxic and side effects on the
human body; 2, the microcapsule with the TEOS as the wall material has good heat resistance
and mechanical property, so that the microcapsule with a natural polymer as the wall material
may be effectively prevented from being broken in a high-temperature setting process so as to
cause release of the core material; 3, the heat resistance of the microcapsule modified by
means of the organosilicon quaternary ammonium salt is further improved, finishing is
conducted without adding any adhesion agent, and the microcapsule may bond covalently to
the fabric firmly; and 4, the finished fabric has the long lasting skin-care anti-bacteria
function, and the style of the fabric is not influenced afterfinishing.
