Preparation for natural colored cotton far infrared yarn

Abstract

A natural colour cotton far infrared yarn preparing method, belongs to the textile technique field, which is used to solve the problem of taking the natural colour cotton as materials to produce far infrared yarn, which has the processes of opening and picking, dressing process, drawing, roving, spun yarn, etc. After improvement, the invention takes the natural colour cotton as materials, uniformly injects the finishing liquid containing far infrared ceramic powder to seed-wool in front of the cotton ginning, the finishing liquid adopts the following raw materials to mix the water solution, 15-25g / L of far infrared nano ceramic powder and 10-15g / L of hydrosol; and the inject amount required by each ton seed-wool is about 20-30 kg of the water solution. According to the features of the color cotton fibre after adding far infrared materials, the invention formulates the processing parameter of processes of opening and picking, dressing process, drawing, roving, spun yarn, etc., which allows the spinning process to succeed. Indicated by experiments, after the inventive natural colour cotton far infrared yarn is weaved into finish product facing material, the infrared emissivity is more than 85% after being washed for 100 times, which is better than any of the existing far-infrared ray topical finish textiles.

Description

technical field [0001] The invention relates to a method for manufacturing textile materials, in particular to a method for manufacturing natural colored cotton far-infrared yarns containing functional additives, and belongs to the field of textile technology. Background technique [0002] Infrared ray is a kind of radiation emitted by hot objects. Its wavelength is outside the red end of the visible spectrum. It is an electromagnetic wave with a wavelength of 0.76-1000 microns during the vibration and rotation of chemical bonds in a substance. The absolute temperature is above zero. Any substance can emit far infrared rays. The wavelength range of far-infrared rays is usually 2.5-30 μm, and its characteristics are: 1. Strong radiation ability, which can directly heat the target without heating up the gas or other objects in the space; 2. Far-infrared rays can be absorbed by various objects in the same wavelength range 3. Far-infrared rays can penetrate into the subcutaneou...
