Process for preparing tourmaline fibers and sugarcane fiber knitted underwear with health protection and sunscreen effects

Abstract

The invention provides a process for preparing tourmaline fibers and sugarcane fiber knitted underwear with health protection and sunscreen effects. The process comprises the steps of making yarn covered cores, selecting yarns, refining, dyeing, performing compound weaving, leaching, performing spice finishing, softening, drying and sizing by steaming. The method is simple in production process, and is suitable for industrial production; and the seamless knitted underwear has remarkable characteristics in function, comfort, attractive appearance, environmental friendliness and the like, dyeing on the outer side of the underwear has excellent softness, bright color and sunscreen effects, and yarns close to skin are not dyed to achieve health protection and sterilization functions.

Description

technical field [0001] The invention relates to a preparation process of tourmaline fiber and sugarcane fiber knitted underwear with health care and sun protection. Background technique [0002] Sugarcane fiber is processed from bagasse, which was only used as a fertilizer in the past, but today it is regarded as an ecologically friendly fiber resource, which is gradually used in the fiber spinning industry through technical processing. There are two main steps in sugarcane fiber processing, one is mechanical separation and the other is chemical treatment. The raw material for many of these nonwovens is bagasse. Bagasse is rich in cellulose and lignin, and the polymers in the fiber are about 2000-3000 units. In order to obtain fiber materials, firstly, slag treatment is carried out to extract fibers, or a series of chemical processing is carried out, and then the network fiber materials are obtained. This material becomes fiber filaments that can be seen with the naked ey...

Problems solved by technology

[0003] With the continuous advancement of health care technology, tourmaline has been increasingly valued by experts at home and abroad because of its high technological content, strong health care functions, long-lasting effects, and wide application range. There are huge development prospects in agriculture, animal husbandry, etc., and it is known as a new environmentally friendly and healthy material in the 21st century, but it has not been applied to the weaving of knitted underwear products at present.
