Problems solved by technology

Because this method does not use control measures such as oxidants and related processes and equipment, it cannot effectively control the redox process of indigo and anthraquinone vat dyes, and the colored viscose fiber obtained has unstable color and poor spinnability. , unable to achieve industrialized mass production, it is also impossible to make embroidery thread

Embodiment 1

[0052] Example 1: acid environment oxidation

[0053] A. Preparation of color paste: According to the requirements of viscose fiber color, weigh a certain amount of one or several dyes according to the concentration ratio, mix and disperse them in desalted water, add alkaline solution, and then according to the reaction molar ratio, in Add reducing agent and oxidizing agent to the solution, and finally use desalinated water to make up the volume, then filter the solution into the storage tank, filter to remove particulate impurities, and make a color paste for later use;

[0054] Wherein, the adding amount of the reducing agent and the oxidizing agent is respectively 1-5 times and 0.5-2 times of the reaction mole number.

[0055] Dyes include: vat dyes, sulfur dyes, water-insoluble organic dyes

[0056] Alkaline solution can use NaOH aqueous solution.

[0057] Reaction molar ratio: determined according to the reaction formula of different dyes.

[0058] The reducing agent i...

Embodiment 3

[0109] Embodiment 3: embroidery thread production method

[0110] After the humidity-conditioning process in Example 1 and Example 2, the spun and dyed viscose fiber cakes are ternary, twisted, twisted or rolled into colored embroidery threads. Processes such as skeining, dyeing, opening, and barreling of colored silk are omitted. The obtained embroidery thread product indicators: embroidery thread dry breaking strength 1.5~3.0CN / dtex; dry breaking strength variation coefficient 0~8%; dry extension 15~30%; twist variation coefficient 0~10%; broken end rate 0~1 ‰; moisture regain 8 ~ 20%.

[0111] The characteristics of embroidery thread products are: full color, rich colors, comfortable hand feeling, high color fastness, no pollution in subsequent processing, and convenient use.

[0112] The following are the product indicators of several grades of embroidery threads:

Abstract

The invention discloses a viscose fiber spinning dyed stitch yarn and the production process thereof, and overcomes the problems of tinted yarn, such as poor spinning property, high production costs, dull color of product and failure to produce stitch yarns. The raw materials used in the invention comprises a dyeing viscose glue which is a mixture of color paste and viscose glue, a base solution, a reducer and an oxidizer. Reduced threads made from the dyeing viscose glue are directly processed to viscose fiber spinning dyed stitch yarns in the refining procedure, with the action of oxidizer and acid or base. The invention has the advantages of uniform dyeing, high color fastness and color brightness, rich colors, compliance with the standards of stitch yarn, reduced production costs, no contamination of the next processing, comfortable feeling, and wide application range.

Description

technical field [0001] The invention relates to artificial fibers and a production method of artificial fibers, in particular to a viscose fiber spinning and dyeing embroidery thread for dyeing silk strips in the spinning process and a production method thereof. Background technique [0002] Man-made fibers are also called rayon, viscose fiber, and regenerated cellulose fiber. Viscose color injection before spinning or post-dyeing and finishing processing can make man-made fiber products of various colors, which are widely used in yarn-dyed, home textiles, gold and silver silk, Embroidery thread and yarn field. [0003] Dyeing after filament forming, referred to as post-spinning dyeing, is an obsolete process, which has disadvantages such as complicated process, high cost, and large sewage discharge. So in recent years, the pre-spinning coloring process has been proposed. That is to say, the pigment is injected into the viscose to become colored viscose, and then spinning....
