Health-care spandex fiber and preparation method thereof

Abstract

The invention provides a health-care spandex fiber which is formed by combining a wrapper and a core part, wherein the section of the fiber is solid; the mass percentage of the core part accounts for 30-70% of that of the fiber and the mass percentage of the wrapper accounts for 30-70% of that of the fiber; and a preparation method of the health-care spandex fiber comprises the following steps of: 1, preparing a health-care spandex core part by utilizing a melt spinning technology according to a formula proportion; 2, preparing a health-care spandex fiber wrapper by utilizing a dry-method spinning technology according to the proportion; and 3, spinning by utilizing a special spinneret plate combined piece through a conventional dry-method spinning equipment process so as to obtain a health-care spandex. The health-care spandex disclosed by the invention has the effects of eliminating the peculiar smell, absorbing the moisture and proofing moulds, and inhibiting bacteria and expelling parasites; the health-care spandex can be contacted with a human body to remove the humidity and absorb the sweat so as to accelerate the blood circulation and the metabolism of the human body and relieve fatigues; and the health-care spandex also has the aroma of plant essences, and furthermore is good in utilization performance and can meet the requirements on homespun in processes of spinning, weaving, dyeing and finishing.

Description

technical field [0001] The invention relates to a functional chemical fiber and its manufacturing method, in particular to a health-care spandex fiber and its manufacturing method by applying composite spinning technology and combining melt spinning and dry spinning technology. Background technique [0002] Spandex is a kind of polyurethane elastic fiber, known as "fabric monosodium glutamate", and there is a saying in the industry that "no ammonia can't make cloth". It can be seen that spandex is one of the key factors to improve the quality of fabrics. With the continuous progress of society, human beings have higher and higher requirements for the quality of life, and "clothes", as the main factor affecting people's livelihood, must also keep up with the development of the times. Health care spandex was invented in response to this trend. It has the functions of eliminating peculiar smell, moisture absorption, mildew resistance, antibacterial and insect repellent, dehumid...

AI Technical Summary

Problems solved by technology

The fibers prepared by the above method have poor functional stability, and because the addition of a large amount of functional materials seriously affects the performance of the product, the application field is narrow

[0005] Second, form a sheath / core structure through composite spinning technology, such as US Patent US4713291, Japanese Patent JP61063716, and Chinese Invention Patent CN85108805. The nature of the / core is different, and the shape of the end face is greatly different, which affects the performance

[0006] Within the scope known to the applicant, there is no report on the preparation of spandex with multiple health functions by using melt spinning and dry spinning technology at the same time
