Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of textile industry, and relates to a calamine viscose fiber, and to a method for preparing calamine viscose fiber and a use thereof. BACKGROUND OF THE INVENTION Viscose fiber is a regenerated cellulose fiber, and has a molecular formula of (C _e H ₁₍₎ C n, n is a degree of polymerization. It is based on natural cellulose such as wood, reed, and cotton linters in nature. The process of alkalization, aging, yellowing, etc. is made into soluble cellulose xanthate, which is dissolved in dilute alkali solution to make viscose and made by wet spinning. It is the first chemical fiber in the world to be industrially produced. 1. Viscose fiber is divided into two types: filament and short fiber. Viscose filament is also called rayon or viscose; and viscose staple fiber is cotton (also called rayon), wool type (called artificial wool). ) and medium and long fiber. Because the properties of viscose fiber are close to natural fiber, it has good hygroscopicity and moisture content which meets the physiological requirements of human skin. It has smooth, breathable, antistatic, dyed and beautiful characteristics, and is soft and comfortable to wear. It has excellent spinnability, so it can be purely spun, or blended with cotton, wool or various synthetic fibers, and used for all kinds of clothing and decorative textiles. Moreover, after the fabric of viscose fiber is discarded, it can be biodegraded. It does not affect the accumulation of the environment.

Calamine has a high medicinal and health value, and the medicinal function of calamine is recorded in many ancient books of ancient medicine and modern pharmacopoeia. Calamine is a natural medicinal material, drug name: calamine, English name: luganshi, taste: Gan, Ping. Go to the liver, stomach. The main components of calamine are zinc carbonate (ZnCO ₃ ), aqueous zinc carbonate (ZnC0 ₃ ·2Ζη (OH) ₂ ·Η ₂ 0 ), and zinc oxide (Zn0). Calamine effect: Detoxification eyesight, to remove phlegm, use the treatment of red swelling and pain, eye deciduous film, bad string wind eye; Humidity and itching, sore muscle sore, use eczema wet sore, ulcers are not concentrated . It can be used clinically for the treatment of a variety of contact dermatitis-skin conditions, especially for the treatment of ulcers, pus, wet sores, itchy skin and other diseases.

Although viscose and calamine have their own characteristics, so far, no one has combined viscose fiber with calamine, so that one product has the advantages of two substances at the same time. After understanding and mastering the characteristics of viscose fiber and calamine, the inventors have worked hard to combine the viscose fiber textiles with the health care function of calamine, and the present invention has been produced. SUMMARY OF THE INVENTION It is an object of the present invention to provide a calamine viscose fiber which has a viscose fiber.

Confirmation It is also natural, degradable, soft, and excellent dyeing properties. It also imparts medicinal and health-care functions and improves material quality.

Another object of the invention is a method of preparing a calamine viscose fiber and its use.

In order to achieve the above object, the solution of the present invention is:

The calamine viscose fiber contains 1% to 6% of calamine powder in the fiber based on the total dry basis weight of the fiber, and the calamine powder is uniformly dispersed inside and on the surface of the fiber.

The above viscose fiber is a viscose filament or a viscose staple fiber.

The calamine powder described above is a micron-sized particle having an average particle diameter of 1 μm.

The method for preparing the calamine viscose fiber, the calamine powder is blended with the dissolved viscose in an amount of 1% to 6% based on the total weight of the fiber dry basis, and the mixture is thoroughly stirred, filtered, and vacuum defoamed. The calamine viscose filament obtained by the filament production line; or the calamine viscose staple fiber obtained by the short fiber production line.

The method for preparing calamine viscose fiber, the calamine powder is directly blended with the spinning viscose by a pre-spinning syringe device in an amount of 1% to 6% based on the total weight of the fiber dry basis, and then passed through a filament production line. , that is, a calamine viscose filament obtained; or a calamine viscose staple fiber obtained by a short fiber production line.

The above calamine dissolution formula is: calamine 5% - 15%, water 85% - 95%.

The application range of calamine viscose fiber is: calamine viscose filament can be directly spun, or interlaced with cotton and chemical fiber, and short fiber can be blended with short fibers of cotton, acrylic, polyester, etc. Used in underwear, t-shirts, pajamas, shirts, dresses, bedding, etc.

In the present invention, since the calamine powder particles are uniformly dispersed in the fibers, the powder is firmly integrated with the fibers in the inside and the surface of the fibers. Calamine powder has good compatibility and dispersibility, is resistant to washing, light, and high temperature, and has good dyeability and spinnability of viscose fiber. The calamine viscose fiber is obtained by the above method, and has broad-spectrum antibacterial and antibacterial long-lasting effects. It has significant anti-bacterial effects against Staphylococcus aureus, Escherichia coli, and Candida albicans. It provides health and auxiliary medical care for the treatment of patients with various contact dermatitis-skin disorders.

This calamine viscose fiber is a functional fiber added. In addition to the natural, degradable, soft, and excellent dyeing properties of viscose fiber, it also imparts medicinal and health-care functions and has various physiological functions. The activity helps to enhance the vitality of the cells, and can regulate the skin and the body to maintain health. Moreover, the calamine viscose fiber also has remarkable anti-ultraviolet properties and improves the material quality.

The experiment proves that: the quality of the calamine viscose filament of the invention conforms to the standard of GB/T13758-92-; the quality of the calamine viscose staple fiber conforms to the standard of GB/T14463-93-. detailed description
