Problems solved by technology

Although it uses a specific soaking solution to modify the fabric to obtain a fabric with a specific effect, the resulting fabric does not have anti-ultraviolet properties or antibacterial properties, and the fiber fabric has poor breathable and sweat-absorbing properties and poor comfort; Chinese patent ( CN108468134A) discloses a processing method of an antibacterial anti-fluffing fabric, in which the warp and weft are woven into the desired fabric, the warp is made of polyester fiber and bamboo fiber blended weaving, and then the fabric is dipped in the antibacterial finishing liquid dealt with
Although it adopts antibacterial liquid dipping to process the fabric with antibacterial effect, it does not have anti-ultraviolet and antistatic effects, and has poor breathable and sweat-absorbing properties; Chinese patent (CN108642674A) discloses a new type of antibacterial fabric. Fiber, the weft is made of polyester filament fiber, this fabric is antibacterial and deodorizing, prevents static electricity, and is more comfortable to wear
Although it claims to obtain uniform antibacterial and antistatic effects of fabrics, its antibacterial and antistatic effects are not obvious, there is no special modification treatment for warp and weft warp, and it does not have anti-ultraviolet performance; Chinese patent (CN107881596A) a Antistatic textile fabrics are woven from warp and weft threads covered with antistatic films. Although antistatic fabrics can also be obtained, they have poor air permeability and comfort, and do not have anti-ultraviolet and antibacterial effects; China Patent (CN203137151U) discloses a UV-resistant swimsuit fabric, which is divided into inner and outer layers, the inner layer is interwoven with warp yarns and weft yarns, and the outer layer is an anti-ultraviolet layer
The fabric has good air permeability, good comfort, and good UV resistance. Although it has a certain UV resistance, it is specially equipped with an UV layer, resulting in poor flexibility of the fabric, which is not suitable for casual clothing. Antistatic and antibacterial properties

Abstract

The invention relates to the technical field of fabric preparation, in particular to a preparation method of a fiber fabric with an ultraviolet resistant function. Under the effect of ultrasonic dispersion, a PK-antistatic agent can be uniformly dispersed into an inorganic phase composed of an ammonium persulfate solution and uniformly attached to the surface of a chitin fiber, 4,4'-dihydroxybenzophenone added later interacts with hydroxyl and amino groups on the surface of the chitin fiber to form chemical bonds with a strong acting force, and the PK-antistatic agent is fixed into a three-dimensional network structure composed of the chitin fiber and 4,4'-dihydroxybenzophenone, so that the fabric has a strong and long-lasting ultraviolet resistant function; a mulberry bark fiber and isothiazolinone adopt Y-methacryloyloxy propyltrimethoxysilane as a connection bridge, so that isothiazolinone is firmly fixed to the surface of the mulberry bark fiber in a chemical bond form, and the antibacterial performance of the mulberry bark fiber is improved. The fiber fabric can also release negative ions and far infrared rays beneficial to human health and achieve very good health care and warm keeping effects.

Description

Technical field [0001] The invention relates to the technical field of fabric preparation, in particular to a method for preparing a fiber fabric with anti-ultraviolet function. Background technique [0002] Fabric is the material used to make clothing. As one of the three elements of clothing, fabrics can not only interpret the style and characteristics of clothing, but also directly influence the color and shape of clothing. Analyzing and identifying the properties of fabrics and applying them to clothing design accurately and reasonably is the basic knowledge that every designer needs to master. Otherwise, errors in fabric identification may cause problems in the design, production, wearing or washing of the entire clothing. The identification of apparel fabrics includes raw material identification, appearance feature identification and appearance quality identification of apparel fabrics. Observing and identifying fabrics requires not only vision, but also hearing, touch an...
