Background
With the improvement of living standard of substances, the requirements of people on textiles are not limited to the original basic characteristics of shielding, cold avoidance, comfort and the like, but are favored by textiles with functionality, such as antibiosis, anion, ultraviolet resistance and the like. With the health emphasis of people, the market increasingly demands textiles with special functions of antibiosis, health care and the like. Modern clothing is required to have fashionable and attractive social attributes, ultraviolet properties are ubiquitous, moderate ultraviolet radiation is beneficial to body health, clothing is generally light and thin in summer weather, skin is easy to be damaged by ultraviolet rays, the ultraviolet rays are the first natural enemies of people who love beauty and pursue health preservation, and once the ultraviolet rays are too strong, the clothing can cause harm to body health, skin cancer is caused, and even sick health is damaged. Therefore, whether the clothes have the antibacterial, health-care and ultraviolet-resistant performances is important except that basic requirements of skin-friendly comfort, air exhaust, moisture permeability, light weight, elegance and the like are met.
In addition, nowadays, people enter a fast fashion life rhythm, the use of clothes of young fashion ladies generally does not exceed 2 years, and old clothes without reuse value can be thoroughly discarded due to aesthetic fatigue or a fresh style which is introduced into the market, so that great waste is caused, and the energy conservation and environmental protection are not facilitated.
Disclosure of Invention
The invention aims to provide a novel environment-friendly composite fabric with antibacterial, health-care and ultraviolet-proof functions.
In the present invention, "wt%" represents a mass percentage; in the blending ratio of each yarn in the present invention, the component ratios in each raw material are by weight unless otherwise specified.
The invention relates to an antibacterial, health-care and anti-ultraviolet environment-friendly composite fabric which is composed of an outer layer fabric, an interlayer fabric and an inner layer fabric, and is characterized in that,
the outer fabric is a satin weave made of cotton/polylactic acid fiber blended yarns A and polyester yarns, wherein the blending ratio of cotton to polylactic acid fiber of the cotton/polylactic acid fiber blended yarns is 25-35 wt% to 75-65 wt%;
the interlayer fabric is a through hole tissue made of soybean protein fiber yarns;
the inner layer fabric is a plain weave made of cotton/polylactic acid fiber blended yarns B, wherein the blending ratio of cotton to polylactic acid fiber of the cotton/polylactic acid fiber blended yarns is 18-22 wt% to 78-82 wt%;
the three layers of fabrics are bonded by reactive glue, and the reactive glue comprises the following components: 55-65 wt% of ethyl acrylate/acrylic ester copolymer emulsion, 17-22 wt% of chitin and 17-23 wt% of polylactic acid (polylactide).
The antibacterial health-care and anti-ultraviolet environment-friendly composite fabric is formed by compounding three layers of fabrics with different tissue structures, and has the advantages of antibacterial health care, ultraviolet resistance, environment friendliness and the like. The outer layer fabric is used as the outermost layer, and the composite fabric is endowed with excellent ultraviolet resistance and antibacterial performance. Firstly, the outer layer fabric is made according to a satin weave structure, so that the uvioresistant performance of the fabric can be effectively improved. The weave structure is different, the interweaving rule of the yarns is different, and the size of gaps among the yarns is different. At the same yarn density, the number of plain weaves is the largest, and many gaps are generated between yarns. The twill and the satin are different, particularly, the satin weave is long in floating, the interweaving times among yarns are small, the yarns are easy to be close to each other under the condition of the same density, gaps are small, the thread jumper on the satin is long, an included angle is small, the gloss is strong, the satin is smooth and attractive, and the ultraviolet resistance is good. And secondly, the warp and weft yarns of the outer layer fabric are polylactic acid yarns and polyester yarns, which have good ultraviolet resistance, and especially, the polyester has strong absorptivity for ultraviolet rays with the wavelength less than 300nm due to benzene rings in the molecular structure of the polyester, so that the ultraviolet resistance can be further improved. In addition, the polyester fiber has good strength and low price, and the polylactic acid yarn has better antibacterial performance.
The interlayer fabric is used as the middle layer, and has great influence on the light weight, the air exhaust, the moisture permeability and other properties of the composite fabric. The warp and weft yarns in the sandwich fabric are all soybean protein fiber yarns, have a through hole tissue structure, and have the advantages of light weight, air exhaust and moisture permeability. The soybean protein fiber yarn has good affinity with human skin, contains various amino acids necessary for human body, and has good antibacterial and health promoting effects. In addition, the soybean protein fiber has good solubility, can be selectively dissolved by biological enzyme (protease) in the later period, and the fabric of the outer layer and the inner layer is not influenced, so that the weight reduction treatment can be carried out on the fabric, the fabric style is lighter and more elegant, and the purposes of reducing weight and renewing use are achieved.
The inner layer fabric is the most close-fitting layer, the invention is made of polylactic acid fiber and cotton fiber blended yarn in a plain weave, and has the following advantages that the plain weave is lighter and thinner, more wear-resistant and more uniform in cloth cover than the fabric with the same specification. And secondly, the raw material adopts polylactic acid fiber and cotton fiber blended yarn, wherein the cotton fiber is soft and skin-friendly and is the most widely used natural fiber, and the polylactic acid fiber not only has excellent antibacterial performance, but also is skin-friendly, beauty and health-care and degradable. The blending ratio of the cotton and the polylactic acid fiber is limited to 20:80, so that the mechanical property of the lining fabric can be effectively improved. With the increase of the proportion of the polylactic acid fiber in the blended yarn, the breaking elongation of the cotton/polylactic acid fiber blended yarn is increased and then decreased, and when the proportion of the polylactic acid fiber in the cotton/polylactic acid fiber blended yarn is 80%, the breaking elongation of the cotton/polylactic acid fiber blended yarn is higher.
The three layers of fabrics are bonded through the reactive glue, the components of the reactive glue comprise ethyl acrylate/acrylate copolymer emulsion, chitin and polylactic acid (polylactide), the reactive glue can react with the fabrics for crosslinking, the fabrics are bonded effectively, and the reactive glue has the advantages of environmental protection, no peculiar smell, no formaldehyde, lasting glue points and the like, and is very in line with the design concept of novel green and environment-friendly fabrics. The fabric bonded by the reactive glue can be dry-cleaned, has less glue amount and soft hand feeling, and is more comfortable and skin-friendly. And the added polylactic acid component is favorable for ultraviolet resistance, antibiosis and health care performance, and the chitin has very good antibiosis performance.
The raw materials of polylactic acid fiber, soybean protein fiber, cotton fiber and anti-reaction glue used by the fabric belong to green environment-friendly materials, and the production and processing of the fabric are beneficial to the safety and health of the ecological environment and accord with the concepts of green economy and sustainable development.

Preferably, the color of the outer layer fabric is designed to be orange, and generally, the darker the color, the better the ultraviolet resistance. The black and blue-hidden ultraviolet-proof performance is relatively good, and the dark fabric absorbs heat most at that time. Meanwhile, in consideration of the fashionable and attractive appearance of the fabric, in the common colors such as blue, white, yellow, red and orange in summer, the orange color has the best ultraviolet resistance and is very striking, so that the fabric is suitable for outdoor sportsmen to wear and use, and in case of threat, the striking color is convenient for rescue.

In addition, the clothes made of the fabric can selectively degrade the interlayer fabric after being used for a period of time, and the fabric is subjected to weight reduction treatment, so that the fabric is lighter, thinner and more elegant in style and can be reused. Nowadays, people enter a fast fashion life rhythm, the clothes of young fashion ladies can not be used for more than 2 years, and the old clothes without reuse value can be completely discarded due to aesthetic fatigue or the fact that a fresh style is introduced into the market. However, if the clothes made of the novel fabric of the invention are used, when a consumer uses the clothes for a period of time and does not want to wear the clothes and discard the clothes, some bio-enzyme detergent can be bought in the market, and the soybean protein fiber is processed, so that the clothes become a light and thin sun-proof clothes which can be used for outdoor sports or on-duty and off-duty roads, can protect ultraviolet rays, can be recycled and is very economical. For consumers who like outdoor sports, the fabric before losing weight is thicker and heavier, and is suitable for wearing in spring and autumn, and if the consumers wear for a period of time and want to discard, the fabric can also lose weight and be used for wearing in summer. The interlayer fabric is independently designed, and the biological enzyme only dissolves the soybean protein fiber, so the plate type cannot be changed.
While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
