Description

Sterilization Knit Cleaner with Excellent Adsorption and Sterilization

The present invention provides a fabric using a silver particle-containing functional nylon yarn and PET / nylon split composite fiber, which has excellent bactericidal properties and has high adsorption and adsorptivity to other contaminants such as dust and moisture. The present invention relates to a method for producing an excellent bacteriostatic cleaner.

More specifically, knitted fabrics that form loops on one or both sides of the fabric using a conventional circular knitting machine using a silver particle-containing functional nylon yarn having a bactericidal resistance against bacteria and a PET / nylon split composite fiber called microfiber. And the weight loss process to form micro-spaces between the fibers to knit so that the pollutants can be easily adsorbed, and at this time, the bacteria containing the silver particles containing viral bacteria that can be generated from the adsorbed pollutants By killing by using the conventional antibacterial functional fabrics that only limit the propagation of bacteria is a method of producing a knitted fabric having excellent bactericidal properties.

Existing knitting cleaners are knitted using yarns called microfibers, and their adsorption properties to the pollutants as fabrics themselves have been functional, but they did not function to suppress the growth and reproduction of bacteria that may occur in the adsorbed pollutants. .

For this reason, antimicrobial treatment is usually performed on the fabric by an antimicrobial compound or a chemical treatment to maintain antimicrobial properties, and fibers containing various antibacterial and deodorant compounds have already been known. However, due to the incomplete coupling of the antimicrobial compound with the fiber, the antimicrobial compound is often desorbed or deteriorated by washing, heating, or ultraviolet irradiation to generate a harmful substance to the human body or the natural environment.

Due to the problems described above, many inventions and designs have been developed in Korea, and attempts to increase antibacterial and antibacterial properties using materials that are harmless to humans are made. Among them, silver, which is known to have excellent bactericidal properties, is harmless to the human body, and it is harmless and non-tolerant. Unlike other general medicines, silver has no side effects and has strong natural hygiene disinfection ability.It is acne, swelling, porridge, eczema, athlete's foot, etc. It is known to improve the skin troubles of the skin to protect and regenerate the skin cells. The filament coating silver on the outside of the yarn was experimentally manufactured by devising a silver powder or a twisted yarn using such a point, but there is a problem such as the sterilization power is greatly reduced after washing or easily detached from the fiber surface.

The present invention is to solve the above problems, an object of the present invention is to produce a knitted fabric using a functional nylon yarn containing a sterilizing silver particles in the yarn and a composite fiber having a heteromorphic cross section and such a knitted fabric is contaminated It is to provide an antibacterial knitted cleaner that effectively removes substances and continuously suppresses and prevents the generation of bacteria regardless of external conditions such as washing.

In order to achieve the above object, the present invention manufactures a knitted fabric using silver particle-containing bactericidal functional nylon yarn and a PET / nylon split composite fiber having a heteromorphic cross section, and forms a microspace between the fibers by reducing the contaminants. It is knitted to be easily adsorbed, and provides a method for producing knitted fabrics having excellent bactericidal properties by using silver ions from the bacterium functional nylon yarn containing silver particles as viral bacteria that may be generated from adsorbed contaminants.

Hereinafter, the present invention will be described in detail.

The method of the present invention uses the silver particle-containing bactericidal functional nylon yarn 10 as a bottom yarn and a PET / nylon split composite fiber 20 as the loop yarn, as shown in FIG. 1. Knit so that loops form continuously. Thereafter, the knitted fabric is reduced in weight to form fine pores in the fabric structure.

PET / nylon split composite fiber 20 used in the present invention has a heteromorphic cross-sectional shape as shown in FIG. 2 but is divided by flammable and alkaline weighted PET in the form of an orange triangle as shown in FIG. 3. Shape changes to nylon split fiber. PET / nylon split composite fiber 20 which is sectionalized by weight reduction process is different from PET polymer 2 and nylon 1 at the boundary between PET polymer 2 and nylon 1, whereas the cross section of ordinary PET fiber is substantially circular. By eluting and modifying the fiber surface, the shape is substantially the shape (2-1) of the shaped cross section such as the triangular cross section, and the nylon (1) is not reduced to alkali. The micropores (7) produced by this weight loss process cause capillary action to easily absorb moisture and contaminants into the fabric, and the absorbed material is released from silver particles (4) inside the antibacterial functional nylon yarn (10). Sterilization is due to the silver ions.

The silver particle-containing bactericidal functional nylon yarn 10 is one of polyamide-based fibers represented by nylon 6 or nylon 66, and is made by ring-opening-polymerization of ε-caprolactam in the presence of water and powdered to the nylon polymer (3) thus synthesized. Of silver particles 4 are mixed to form a cross-sectional structure as shown in FIG. 4 and melt-spun to form a fiber.

The silver particle-containing antibacterial functional nylon yarn 10 and the PET / nylon split composite fiber 20 are commercially available.

Hereinafter, one embodiment of the present invention, but the scope of the present invention is not limited thereto.

Using silver particles-containing antibacterial functional nylon yarn (10) 210 denie / 72 filament as a bottom yarn, PET / nylon split type composite fiber (20) 150 denie / 72 filament is used as a loop yarn to knit in a continuous loop form on the front and back. At this time, the mixing ratio of the silver particle-containing antibacterial functional nylon yarn 10 and the PET / nylon split type composite fiber 20 was 30% mixed with the silver particle-containing antibacterial functional nylon yarn.

The mixing ratio is an ideal bactericidal effect when the silver particle-containing bactericidal functional nylon yarn (10) is blended more than 30%.

The knitted fabric woven in the above is processed as follows.

1. Refinement

: Refining is carried out at 100 degrees for 15 minutes by adding an ordinary refining agent and a water purifying agent.

2. weight loss

: Add 12 g / 1 l of NaOH and reduce the weight for 40 minutes.

In the case of high temperature reduction, 3 g / 1 L of this knitted fabric reduced the temperature. Reduction rate is 10-13%

Through weight loss processing, PET / nylon split composite fiber is divided into microfiber to increase the absorbency and adsorption.

3. Dyeing

: The weight-reduced fabric was washed with water, neutralized and dyed at 100 ° C. for 30 minutes by addition of a conventional dispersant and dye.

4. Drying

: It was dried for 120 seconds at a speed of 3m / 1min using a tunnel dryer at a temperature of 200 degrees.
