Technical Field

The invention relates to the technical field of functional finishing of textile fabrics, in particular to a dyeing, moisturizing and finishing process for a thin polyester fabric.

Background

Due to the enhancement of the consciousness of returning to nature and health protection, functional finishing mainly based on comfort, cleanness, health care and sanitation becomes the subject of the development of textile dyeing and finishing in the century. Meanwhile, with the development of industry, the environmental pollution is increasingly serious, carbon dioxide, nitric oxide and sulfur oxide in the atmosphere are increased, the influence on human bodies is large, and the number of people with allergic constitution is increased, so that the skin care function arrangement attracts attention of people, and more garment fabrics contacting with the skin tend to meet the consciousness of nature and environmental protection. The development of the textile with skin care and health care functions by utilizing natural substances is in line with the development trend, and the product is very popular with consumers.

Under the strong development of science and technology and economy, textiles are no longer textiles in the traditional sense, and they are endowed with a completely new sense. In the past, clothes mainly used for keeping warm are not only provided with simple functions but also provided with simple functions. Besides pursuing beauty, fitness and comfort, the clothes are also expected to be beneficial to skin health, and even have the functions of preventing and treating diseases, so that the skin-care and health-care functional finishing of the textile is more and more valued by people. With the change of social environment, the improvement of living standard of consumers and the diversification of requirements, a plurality of functions are provided for textile materials and clothes to meet the new requirements of environment and physiological requirements. Therefore, multifunctional finishing of textile materials and garments has been rapidly developed. Just as the international well-known clothing trend analysis, aldrich, says: at present, a new trend appears in textiles, namely, the effect of preventing and treating diseases is achieved by utilizing clothes worn by people, so that the life of people is greatly changed, and people are entering a new era of endowing the fabrics with real skin care and health care functions.

The skin care health care fabric extends the original concept, extends from facial skin care to whole body skin care, and extends from general nutrient skin to the level of cleanness, sanitation and comfortable health care. The skin care agent which is very similar to cosmetics is processed and finished on the fabric, and the comprehensive care of the skin of a human body can be realized by wearing the clothes. Besides the ultraviolet-proof fabric for preventing the harm of ultraviolet rays and the medicine health-care fabric for achieving the purposes of treating diseases and losing weight through medicine permeation, the skin-care fabric has the following main functions:

(1) the moisture retention is good, so that the skin is moistened, not dried and not rough;

(2) has antibacterial effect, and can be used for cleaning skin, but natural antibacterial agent is often used;

(3) preventing allergy and skin pruritus.

Aloe vera (Aloe) is a genus of Aloe in the Liliaceae family (liliaceal) of the Liliales order of the Monocotyledoneae class (Monocotyle) and is a perennial fleshy herbaceous seed plant. Aloe is native to tropical and subtropical regions of Africa, and the Aloe genus contains over 400 kinds, and only 5-6 kinds with medicinal value and wide use: aloe barbadensis, Aloe ferox, Aloe arborescens, Aloe chinensis, also known as Aloe chinensis, are a variety of Aloe barbadensis. Chinese aloe leaves have strong meristematic ability and high growth speed, and are mainly produced in Fujian, Guangdong, Guangxi and Yunnan China.

According to research reports, aloe has six main chemical components: anthraquinone compounds, saccharide compounds, protease, amino acids, organic acids, minerals, vitamins and the like. The aloe has abundant physiological activity and pharmacological action because the chemical components of the aloe are very complex and the number of the components with biological activity is less than 100. For example, the anthraquinone compound in the aloe has good antibacterial action and good resistance to a plurality of bacteria such as escherichia coli, staphylococcus aureus, proteus and the like, wherein the barbaloin and the aloe-emodin have the strongest antibacterial ability, and the antibacterial activity of the barbaloin is obviously higher than that of the aloe-emodin; the aloe contains various natural nutrients, and amino acids and compound polysaccharide substances in the aloe form natural moisturizing factors to supplement water loss of skin; the aloe natural anthraquinone glycoside and derivatives of anthracene have good sunscreen and anti-ultraviolet functions.

Aloe is a succulent herb which grows for many years, is used as a pure natural green plant which integrates medicine, beauty treatment, health food and appreciation, and has been pursued and accepted by consumers in developed countries such as the United states. Finishing onto the fiber or fabric can be done in two ways: firstly, the aloe fiber is functional cellulose fiber prepared by adding aloe stock solution into cellulose fiber during spinning by adopting a high-tech means, so that nano aloe stock solution is uniformly distributed in the fiber body and on the surface of the fiber body. The chemical and physical properties of the aloe fiber are very close to those of cotton, so that the aloe fiber has good spinnability. The fabric has the advantages of skin protection, beauty and skin care, good skin affinity, moisture absorption and ventilation, comfortable wearing, easy dyeing at normal temperature, bright color, high color fastness and the like; secondly, the aloe extract is used as the main component and is matched with squalene to prepare turbid white emulsion, the fabric is finished in a post-finishing mode and is fixed on the fabric, and the aloe extract has good moisture retention and antibacterial property and is mainly used for manufacturing underwear, pajamas and baby products.

Hyaluronic acid is also known as glucuronic acid. Hyaluronic acid is a high-molecular mucopolysaccharide with D-N-acetylglucosamine and D-glucuronic acid as structural units, is a transparent natural polysaccharide colloidal crystal, and exists in human connective tissue and dermis in large quantity.

The hyaluronic acid content in human body is about 15g, and the content of human connective tissue extracellular matrix, dermis layer, mucus tissue, eye vitreous body, aqueous humor, synovial fluid, skin and umbilical cord is high. Hyaluronic acid begins to run off at age 18, the content of hyaluronic acid in skin at age 30 is only 65% of that in the period of infants, and is only 25% of that in the period of sixties, when the hyaluronic acid runs off faster than the growth speed, hyaluronic acid is timely supplemented from the outside, the running-off of human collagen and the running-off of hyaluronic acid are carried out simultaneously, and the running-off of human collagen at age 40 reaches 50%.

Hyaluronic acid is a naturally existing filler in skin and plays a role in moisturizing, repairing and nourishing skin. Moisturizing is an important part of skin care. The epidermis is the outermost protective barrier of the skin and normally has a moisture content of 20% to 35%. Hyaluronic acid is one of the most abundant matrices in the dermis, and if the hyaluronic acid in the dermal matrix is reduced, the water content is reduced, and when the water content of the epidermis is reduced to 10%, significant skin dryness occurs: dull, fine lines, roughness and desquamation, reduced elasticity, wrinkles, roughness, dullness, laxity, itching and color spots, and aging phenomena such as arthritis, dry joints, arteriosclerosis, pulse disorders and brain atrophy, skin sagging, hair loss, chapping, blurred vision, etc. may be caused in severe cases. When our body shows this series of manifestations, it means that it is necessary to supplement hyaluronic acid at the same time.

Hyaluronic acid has very good water locking capacity, and lg hyaluronic acid can absorb 500mL of water and is 16 times of collagen. Because hyaluronic acid can absorb a large amount of water, and acts on any skin in any climate and environment, the hyaluronic acid has high water-retaining property, so that the hyaluronic acid added into the fabric finishing agent can effectively keep the water content of the skin and rebuild a water-fat protective film, so that the skin is more tender and glossy. When the clothes finished by hyaluronic acid are worn, the skin is elastic and glossy, and the clothes have a good protective effect on the skin of a human body.

The existing fabric is generally subjected to after-treatment only by adopting one of hyaluronic acid or aloe extract. The hyaluronic acid is independently adopted to treat the fabric, and the fabric is unsatisfactory in antibacterial performance. The aloe extract is singly used for treating the fabric, and although the fabric has antibacterial performance, the aloe extract has a defect in moisturizing performance. However, no fabric which is subjected to after-treatment by adopting two substances is available in the market, so that the moisture retention capacity and the natural antibacterial performance of the fabric can be greatly improved.

Because the terylene fabric is not water-absorbent in the traditional sense, but because the terylene fabric is more in the existing market, the terylene fabric with the functions of moisture retention and antibiosis needs to be provided, so that the application range of the terylene fabric is expanded.
