Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a preparation method of using cationic modified cotton and nanofibers to realize the effect of flower ash spinning, which overcomes the problems in the prior art that electrospinning film is attached to the surface of cotton fibers, and cotton fibers are combined with dyes. Inhomogeneous phenomenon, the defect that the effect of gray yarn is not obvious, in the process of cotton sliver carding in the present invention, cationic modification is carried out to cotton by blending method and electrospinning process, and it can be finished by spinning and dyeing process Produces a yarn or fabric with a gray effect

Embodiment 1

[0036] In this embodiment, the spinning raw material adopts commercially available cotton staple fibers, preferably raw cotton with a length of more than 30 mm, the model is L233A, the polymer of the electrospinning solution is selected from polyacrylonitrile (molecular weight is 85000), and the solvent is N, N— Dimethylformamide (DMF), the cationic modifier is 2,3-epoxypropyl trimethyl ammonium chloride, and the dyeing agent is acid reactive dye yellow RC-3R2% (OWF).

[0037] In this embodiment, the process method of cationic modified cotton and nanofibers to achieve the effect of gray spinning is to obtain gray yarn and fabric through normal spinning and dyeing and finishing processes combined with electrospinning process. The specific steps are as follows:

[0038] Step 1: Mix raw cotton staple fibers with cotton, and then carry out the cotton opening and cleaning process to make uniform cotton laps. After opening and cleaning, the impurity content of the laps is controlled...

Abstract

The invention relates to a preparation method of using cation-modified cotton and nanofibers to realize the effect of gray spinning, comprising: in the process of carding cotton sliver, cationic modification is carried out on cotton by blending method and electrostatic spinning process, The spinning and dyeing process produces a yarn or fabric with a gray effect. The invention greatly shortens the production time of gray yarn, reduces the cost and improves the production efficiency.

Description

technical field [0001] The invention belongs to the field of flower ash yarns or fabrics, and in particular relates to a preparation method for realizing the effect of flower ash spinning by using cationic modified cotton and nanofibers. Background technique [0002] At present, the commonly used yarns in the textile field are divided into two categories: natural yarn and dyed yarn. Natural yarn is spun from fiber through the processes of opening and cleaning, carding, combing, drawing, roving and spun yarn. Dyed yarn is made of The natural color yarn is made into yarns of different colors through the dyeing and finishing process. The melange yarn is made of fibers of different colors and different properties. It has the properties and colors that the natural color yarn and dyed do not have. Gray yarn is a kind of melange yarn. In a broad sense, it refers to monochrome melange yarn. In a narrow sense, it is made of black-dyed fiber and natural color fiber. It is one of the m...
