Embodiment 1

[0061] Example 1: Environmental protection flame retardant viscose filament pink silk 120D

[0062] The treated flame retardant liquid, red slurry and viscose are contacted and mixed according to a certain weight ratio; then mixed mechanically to make it a homogeneous mixed colloid; then defoamed and filtered, Under the action of power (pump or compressed air), it is sent to spinning through the pipeline, and after being solidified into primary filaments in an acid bath, the filament cake is obtained after drawing, and then pressure-washed and solidified, dehydrated and dried. After being graded into tubes, it is the finished product. Among them, the curing temperature is 80 degrees, the concentration is 5 grams per liter, the oiling concentration is 3 grams per liter, and the weight of a single cylinder is 1.2 kilograms.

Embodiment 2

[0063] Example 2: Environmentally friendly flame retardant viscose short silk grass green silk 2D

[0064] The treated flame retardant liquid, color paste and viscose are contacted and mixed according to a certain weight ratio; then mixed mechanically to make it a homogeneous mixed colloid; Under the action of power (pump or compressed air), it is sent to spinning through the pipeline, and after being solidified in the acid bath, it is cut off after being drawn, and then enters the refining machine for refining, washing, curing, oiling, etc., dehydration and drying Dry and fine opening, packing is the finished product. Wherein 1, the washing temperature is 70 degrees, the oiling concentration is 5 grams per liter, and the finished package weighs 250 kilograms.

Embodiment 3

[0066] The present invention contacts and mixes the treated flame retardant liquid and viscose according to a certain weight ratio by changing the color paste or pigment; then mixes it mechanically to make it a homogeneous mixed colloid; Degassing and filtering are carried out, and under the action of power (pump or compressed air), it is sent to spinning through the pipeline, and after being solidified in the acid bath, the silk cake is obtained after drawing, and then pressure washed (or showered) After washing) and curing treatment, dehydration and drying, and after forming into cylinders and grading, it is the finished product. Among them, the curing temperature is 80 degrees, the concentration is 5 grams per liter, the oiling concentration is 3 grams per liter, and the weight of a single cylinder is 1.2 kilograms. Environmentally friendly flame-retardant viscose filament colored filaments of different colors can be produced.

Abstract

The invention relates to a spinning forming technique of environment-friendly flame-retardant viscose fiber colored filament and staple, comprising: leading flame retardant and color paste to be contacted and mixed with viscose filtered by a first stage or a second stage, treating the mixture by the technique of balancing, defoaming, filtering, spinning and curing, and obtaining the finished product; wherein the flame retardant is nitrogen and silicon series of environment-friendly flame retardant. Therefore, the spinning forming technique solves the problem of dye of the environment-friendly flame-retardant viscose fiber colored filament and staple, can reduce or avoid the pollution for the environment caused by spinning printing and dyeing waste water to the utmost extent, and has the characteristics of energy conservation and emission reduction as well as environmental protection.

Description

technical field [0001] The invention relates to a spinning forming process, in particular to a spinning forming process for colored filaments and short filaments of environmentally friendly flame-retardant viscose fibers. Background technique [0002] At present, in the market, chemical fibers, whether synthetic fibers, viscose fibers, or natural cotton fibers, are easy to burn and cause fires, and flame-retardant fibers can solve these problems, especially flame-retardant viscose produced by adding flame retardants to viscose fibers. Viscose fiber can not only solve the problem that the fiber is easy to catch fire, avoid fire as much as possible and reduce property and life damage, but also maintain the original comfortable and unique performance of viscose fiber. The flame retardants currently on the market are basically halogen-based flame retardants, so the fibers produced are not environmentally friendly, including the most widely used phosphorus-based flame retardants ...
