The preparation method of wet easy-to-clean textile finishing agent and application belong to textile chemistry and arrange processing technique field.
Background technology
Skin is the natural coat of human body, is generally divided into epidermis, corium and subcutaneous tissue three parts, skin from outside to inside
Outermost cuticula completely plays critically important effect for skin barrier function.There is one layer of sebum film to be above cuticula
The translucent oily film formed by sebum, sweat and epidermal cell secretion, free fatty, lactic acid in sebum film
Salt, urea and uric acid are natural moisturizing factor, play moisture-keeping function to skin, cuticula and sebum film can prevent moisture of skin
Loss, under normal circumstances, the water content of cuticula should be horizontal less than this 10% or so, just will produce surface water shortage
Symptom.
Dry skin refers to because of reasons such as seasonal variations water shortages so that skin thickens, is roughening；Autumn and winter, human body
Sebum, moisture content secretion can gradually decrease, and skin obviously becomes drying, the especially middle-aged and the old because moisture content largely reduces, skin table
Layer can seem more rough, can cause trick, have the phenomenon that dry and cracked, itch at shank, skin can be caused to generate chap when serious
Split phenomena such as causing inflammation or suppurating.
Pure cotton fabric can absorb moisture, standard contains as the deep natural fiber liked by consumer into ambient atmosphere
Water rate is about 8% or so, its moisture content is far below needs of the human normal skin to ambient humidity in winter, therefore easily causes
Pruitus of mid-aged population etc. influences the physiological signs of health.
The second layer skin of cotton textile, especially underwear as human body, performance are largely easypro with human body
Adaptive and health are closely bound up, and it is that current piece market and people give birth to high-quality to develop the textile with healthcare function
The new demand living proposed.
Develop all-cotton fabric moisturizing, easy decontamination and washable function, it is intended that the finishing functions scope of abundant cotton fabric improves cotton
Fabric takes quality, and from the perspective of current health care, which has wide development and application foreground.
