Polyester-cotton fabric finishing by wicking anti-bacterial deodorant, so that polyester-cotton blended fabric comfort in the use of this traditional product performance and health conditions have fundamentally improved. In this paper, the principle of finishing, process, test methods, and gave specific descriptions.
As people¡¯s living standards improve, more and more particular about clothing. People¡¯s clothing is no longer just style, color change, people fabric comfort, health, safety and environmental protection, etc. have become increasingly demanding. Is well known: its absorbent polyester fiber is small, breathable performance is poor, because of their accumulation of static electricity generated when entangled easily lead to the trouble of wearing, especially in activities susceptible to hot and sense of belonging; cotton fiber moisture absorption is good, wear comfortable, but the When the amount of people sweating slightly, the cotton fiber mixed with a result of expansion of smoke, its permeability decreased and paste on the skin, while moisture divergence has been slower, thus creating a cold wet sense of the human body. Polyester / cotton blended fabric as an integral part of the fabric, how to maintain its smooth feel, anti-wrinkle good, excellent strength and dimensional stability, as well as easy to wash and quick-drying characteristics such as polyester fabrics to overcome its own shortcomings, as its unique hydrophobicity caused by moisture absorption fabric small, poor ventilation, perspiration caused by bacteria breeding, affecting people¡¯s health and other disadvantages. Improve the polyester / cotton blend fabric of these shortcomings, improve the fabric grades, and has turned into concern. To this end, we use high-tech Co., Ltd. Beijing Jlsun the wicking agent SW and antibacterial finishing agent SCJ-891, from the comfort and moisture absorption fabric anti-bacterial odor begin to change the polyester / cotton blend fabric fabric performance, so that reach a good comfort permeability, and increased anti-bacterial and anti-static function to improve the grade of the fabric.
1, anti-bacterial and wicking polyester-cotton fabric finishing the necessity of
People using conventional cotton textile products, due to the hydrophobic polyester fibers, fabrics showed little moisture absorption, poor ventilation, Khan ulcer can not be discharged timely and effective manner, while synthetic fibers produced by static electricity will be greatly reduced to wearing comfort . In the wear process, the clothing fabrics are generally the existence of micro-organisms, they can multiply rapidly under appropriate conditions, stained with sweat and body secretions and to fabrics produced smell, severe Shi Hai will produce Mildew and the mere mention of the fabric . Although the microbial degradation of synthetic fiber can not be, but its moisture absorption is poor, more poor performance of their health, different types of fabric on the retention of micro-organisms are also different.
Clinical studies have indicated that wearing synthetic fiber socks foot infections more likely than those who wear natural fiber socks are great, and the bacteria from the inoculation of nylon socks can not wash away interdigital dermatophytes. Japanese scholars nylon, polypropylene, polyester, acrylic, cotton and wool socks for adult men and women wear 1-2 months, found that bacteria in the polyester, polypropylene socks on the largest, with wool, cotton socks at least. This shows that the cotton, wool socks, pairs of sweat and other water-soluble pollutants, with good absorption, but with the Sweat-absorbent socks made of synthetic fibers poor, the skin surface residual dirt and socks inside temperature and humidity combination of micro-organisms on the easy to breed. The results show that commonly used PCE (petroleum dry cleaners, four vinyl chloride), and dry-cleaning process, the fabric after dry cleaning and no thin-film filters PCE in dry-cleaning machine, many bacteria are still alive. A number of bacterial contamination of dirty clothes from the move to clean clothes. Common cold water washing on the removal of harmful micro-organisms essentially null and void, you must use bleach disinfection methods such as Cai Xing.
Bacteria produce will have the following adverse effects:
(1) The bacteria produce odor:
Clothing will produce odor, first of all caused by bacteria. Because the bacteria metabolism, metabolic product will produce sulfides or nitrides of the odor. Fecal bacteria in human sweat and also as a result of chemical reaction, the smell. Thus, half of the smell caused by bacteria. If there is no bacteria, odor and fewer than half. The other - one would make clothes smell because the odor produced. It can be seen, anti-bacterial can indeed get rid of a part of the smell. Today, most goods would be anti-bacterial and deodorizing two functions together, it is such a reason.
(2) caused by bacteria fade
Bacteria excrete the acid will cause staining of fabric fading, discoloration, which is another harmful bacteria on textiles. Therefore, anti-bacterial textile finishing, not only for their health, but also for clothing maintenance. This seems to have become the anti-bacterial fiber material must have a function, not just the performance of only a plus.
To sum up, solve the polyester-cotton fabric moisture absorption and increased anti-bacterial function is to improve the performance of their taking an important way.
2, anti-bacterial wicking finishing the principle of
(1) Quick Dry Finishing
Wicking finishing, by definition is to make the fabric of both water absorption and quick drying.
(a) fiber absorbent
Wicking fiber has the characteristics of water absorption is the fiber surface, there are many internal and external communication of the micro-or fibril gap and surface groove, allowing easy access to inter-fiber water. At the same time, a lot along the fiber axis direction of the grooves, or capillary tubes, provide access for the migration of moisture, so there is a good absorbent fibers. After the absorbent as cotton does not appear as a result of water absorption and swelling phenomenon.
(b) drying of fiber
Polyester fibers rely mainly on water in a large number of micro-capillary fiber grip of gravity is, or the machinery to maintain the capillary fibers, in the normal ambient temperature water easily transported to the fiber surface and the evaporation off.
Wicking fibers generally have a higher ratio of surface area, surface, or a large number of micro-grooves, the cross-sectional differences in general as a unique shape, the use of capillary effect, the fiber surface of the skin quickly absorbs moisture and sweat, through the proliferation, passed to the outer layer of evaporation.
Moisture wicking performance fibers depends on its chemical composition and physical structure and morphology. Evaporation from the skin surface, gaseous water is first fiber material absorption, we call the process of moisture absorption. Released by the fiber surface after the wet, while the skin surface of the liquid water points by the fibers within the capillary, microporous, groove, and the gap between the fibers produced by the capillary effect so that moisture in the fiber material between the surface adsorption, diffusion and evaporation This process is put wet process. The result of two processes resulted in a moisture migration, the former function is mainly the chemical composition and fiber molecules related to the latter effect is the physical structure and morphology and fiber related.
The general principle of smoke mixed with perspiration order by grafting or copolymerization methods in molecular structure to introduce hydrophilic groups to increase the fiber moisture wicking capabilities. Is usually the introduction of carboxyl, amide, hydroxyl and amino, etc., to increase affinity for water molecules, so that fibers with a porous structure and larger specific surface area and so on.
Generally speaking, because cotton is a hydrophilic fiber, good water absorption, while the polyester fibers are hydrophobic fibers, does not have the hydrophilic groups, so poor moisture absorption. Test fiber moisture wicking fabric is a basic assessment methods. Said that the capacity of moisture-absorbent fabric, sweat drying fabric of that capability. Hygroscopic and antibacterial deodorant according to functional requirements, we have adopted high-tech Co., Ltd. Beijing Jlsun wicking agent produced by SW and antibacterial, deodorizing SCJ-891, the use of polyester fiber and hydrophilic copolymer crystallization reaction occurs in the fiber hydrophilic surface layer of polyester fiber to maintain a good moisture transmission, thereby enhancing the fabric comfort, reduce electrostatic adsorption on the garment, and can be repeatedly washed. The polyester-cotton fabric after finishing with the following features:
(a) absorb moisture permeability: the finished fabric Excellent sweat absorption, ventilation is good, taking the nature of excellent moisture quick-drying, sweat and moisture quickly away from the skin surface conductivity can be eliminated by the body dry synthetic fabrics, airtight and non - Sweat-absorbent and other shortcomings.
(b) hydrophilic antistatic property: the finished fabric hydrophilic excellent performance, good anti-static, electrostatic effect is small, easy cleaning, there is a certain anti-fouling, easy washing.
(c) Flexibility: the finished fabric a soft smooth, feeling comfortable, elegant style.
(2) anti-bacterial deodorant finishing
SCJ-891 anti-bacterial fabric after finishing with a clear anti-bacterial, anti-inflammatory, anti-odor, anti-mildew, itching, convergence effect, anti-bacterial, deodorizing SCJ-891 at high temperatures when the dye inside the fiber can be carried out with the dye-bath after treatment The fabric has excellent wearability and excellent washing fastness.
Antibacterial odor the whole agent SCJ-891 are buried organic antibacterial agents, it has the following features:
(a) highly effective: only a small amount can provide excellent anti-bacterial effect.
(b) a high degree of firm: SCJ-891 can be fixed on the fiber within the fiber was protected, thus providing superior functionality and washing fastness.
(c) fresh and durable: The results indicate that the use of SCJ-891 can reduce the bad smell generated within textiles.
(d) the safety of users: SCJ-891 contained in the antimicrobial agent has been used in cosmetics and household goods for more than a decade, and proved safe, reliable, harmless to skin.
(e) a high dyeing rate: for environmental security.

Note: Due to moisture finishing agent with the polyester unit of molecular crystal composed of the same shape, at a high temperature to produce crystalline reaction, so that the surface moisture layer of polyester, which has a hydrophilic. In the finishing process, the softening agent used is very important, we must employ hydrophilic softener, can the effect of the fine hydrophilic polyester-cotton fabric. For some there is water repellent effect of the softening agent after the entry of the graft will hinder the pro-channels, to resist the formation of water film.
4, test results
Currently there is no comfort to the moisture uniform standards, but based on the first sweat, wet clothes, and then penetrate into the surface of the heat through evaporation, we use the capillary effect and the effect of water droplets spread to detect moisture.
Evaluation of fabric comfort features indicators include the following three points: textiles for the heat transfer performance of the fabric of the water delivery performance, and the transmission properties of textile products to the air. These three factors for the different seasons and at different levels to take its share of the weight of the fabric is different, winter underwear for the study focused on heat transfer and air delivery of these two factors, the study focused on the summer coat of moisture and air to pass transmission of these two factors.
(1) the capillary effect of the test results
Capillary effect: more than lOcm/3Omim (sampling at three parts of the fabric left, right and finally averaged)
(2) Drop the proliferation of instant results
Methods: In the cloth pad below the five flooded strip, will 5ml of water droplets on the samples cloth to calculate the water droplets needed to fully penetrate the fabric of time (sec), and make 10 times of testing, and then averaged.
