Embodiment 1

[0023] A treatment method for improving the dyeing properties of plant fibers, comprising the steps of:

[0024] (1) Cleaning treatment:

[0025] First put the plant fiber into the acid solution and soak for 6 minutes, then take it out and rinse it with deionized water until it is neutral, and then set it aside;

[0026] (2) Pre-drying treatment:

[0027] Put the plant fibers treated in step (1) into a drying oven to dry until the water content is 35%, and then take them out for use;

[0028] (3) Freezing treatment:

[0029] Put the plant fibers treated in step (2) into the freezer for freezing treatment, control the freezing temperature to -15°C, and take them out after 2 hours for later use;

[0030] (4) High temperature and high pressure treatment:

[0031] Put the plant fibers treated in step (3) into the airtight tank, and pass water vapor with a temperature of 102°C into the airtight tank, and at the same time increase the pressure in the airtight tank to 0.3MPa, and...

Embodiment 2

[0039] A treatment method for improving the dyeing properties of plant fibers, comprising the steps of:

Abstract

The invention discloses a processing method for improving the dyeing characteristic of a plant fiber. The processing method comprises the following steps: (1) cleaning treatment; (2) predrying treatment; (3) freezing treatment; (4) high-temperature high-pressure treatment; and (5) drying treatment. According to the processing method, special treatment is performed on the plant fiber, so that the dyeing characteristic of the plant fiber is effectively improved; freezing treatment is performed on the fiber with certain moisture content, and moisture is crystallized at a low-temperature condition, so that certain damage on the surface of the fiber is caused, and the organization structure of the fiber is loosened; then high-temperature high-pressure treatment and rapid temperature release andpressure relief treatment are performed, and high temperature and high pressure are utilized to promote dissolution of ice crystal, so that stress deformation of the fiber is generated, and the surface roughness of the fiber is further improved; and finally after temperature release and pressure relief are performed, a large amount of ultrafine fibers are formed on the surface of the fiber, so that the absorption fixation capability of dye particles is improved, and thus the dyeing effect is improved.

Description

technical field [0001] The invention belongs to the technical field of fabric fiber processing, and in particular relates to a processing method for improving the dyeing properties of plant fibers. Background technique [0002] Many existing fabrics are woven from natural plant fibers, which have good wearing characteristics such as skin-friendly, breathable, and sweat-absorbent. With the continuous improvement of people's pursuit, more and more people are pursuing fabric products woven from natural plant fibers. However, there are problems such as poor dyeing effect and poor product appearance after dyeing during the existing plant fiber processing, which reduces its market competitiveness and use value, and needs further improvement. Contents of the invention [0003] The object of the present invention is to provide a treatment method for improving the dyeing properties of plant fibers aiming at the existing problems. [0004] The present invention is achieved through ...
