Problems solved by technology

At present, there are two main methods to realize the surface coloring of textiles: one is to control the dyeing temperature, time and other factors so that the dye is only colored on the surface of the yarn. It is easy to cause uneven dyeing, and the dyeing conditions are difficult to control, and the effect of "white core" is not obvious; the second is to modify the surface of the fiber before dyeing, so that the dye can be quickly colored and fixed on the surface of the fiber in a short period of time. The treatment method first requires the modifier to be treated uniformly on the fiber surface, and must only be modified on the fiber surface, otherwise it is easy to cause uneven dyeing and "white core" effect is not obvious, and there are many processes, chemical additives and energy consumption and Large amount of sewage discharge

Embodiment 1

[0019] Spinning a kind of yarn count is the white core ring dyeing yarn that " core layer " and " cortex " of 35s are cotton fiber, specifically comprises the following steps:

[0020] Step a: Purifying and decolorizing the loose fibers: adding 1% of penetrating agent, 8% of hydrogen peroxide, 10% of sodium hydroxide, and CBI 3 of hydrogen peroxide stabilizer in the bulk fiber dyeing machine in sequence %, weight bath ratio 1:10, rise to 95°C at 1.5°C / min, and keep warm for 180min.

[0021] Step b: coloring processing of loose fibers: coloring the cotton fibers treated in step a to remove impurities and decolorize by adopting a conventional dyeing method with reactive dyes;

[0022] Step c: Spinning spun yarns from uncolored fibers: spinning the cotton fibers removed and decolorized in step a into 80s spun yarns;

[0023] Step d: spinning colored roving sliver: spinning the colored cotton fiber processed in step b into roving sliver;

[0024] Step e: Spinning "white core" ri...

Embodiment 2

[0026] Spinning a kind of " core layer " that yarn count is 20s is viscose fiber, and " cortex " is the white core ring dyeing yarn of cotton fiber, specifically comprises the following steps:

[0027] Step a: Removal and decolorization of loose fibers.

[0028] The cotton fiber treatment process is as follows: in the bulk fiber dyeing machine, 1.5% penetrant, 10% hydrogen peroxide, 12% sodium hydroxide, 4% hydrogen peroxide stabilizer CBI are sequentially added according to the percentage of fiber weight, and the weight-to-bath ratio 1:10, rise to 95°C at 1.5°C / min, keep warm for 120min.

[0029] The viscose fiber treatment process is as follows: in the bulk fiber dyeing machine, add 1% of penetrant and 3% of deoiling spirit in the fiber weight percentage, the weight bath ratio is 1: 15, and rise to 90°C at 2°C / min. Keep warm for 45min.

Abstract

The invention relates to a preparation method for yarns in the textile field, and discloses a short-fiber ring dyeing yarn preparation method. The method comprises the following steps: 1, allowing loose fiber to be subjected to impurity-removing and decolorizing processing; 2, allowing the loose fiber to be subjected to coloring processing; 3, spinning the fibers not colored into fine yarns; 4, spinning colored coarse sliver; and 5, spinning the ring dyeing yarn with white core. The method is simple in process, convenient to operate, consumes less dyestuff additive and energy, is small in environment pollution, and large in fiber selectivity for preparing the ring dyeing yarn. Moreover, the prepared yarn has obvious ring dyeing effect, and the ratio of the 'skin layer' to 'core layer' is adjustable.

Description

technical field [0001] The invention relates to a method for preparing yarn in the textile field, in particular to a method for preparing short fiber ring dyed yarn. Background technique [0002] In summer, the temperature is high, and it is difficult for the human body to maintain the balance of body temperature through metabolic processes (such as profuse sweating). In addition to turning on the air conditioner and blowing an electric fan to adjust the temperature, a reasonable choice of clothing fabrics can also play a role in regulating the temperature. For example, wearing fabrics with excellent air permeability and hygroscopicity can significantly reduce the heat that the human body gets from the environment. . In addition, because white or light-colored fabrics absorb less solar radiation than dark-colored fabrics, wearing white or light-colored fabrics can also regulate body temperature to a certain extent. [0003] Because white or light-colored fabrics are not co...
