Problems solved by technology

However, cellulose filaments have the characteristics of high strength, low elongation, and easy slippage. The balls (shafts) for beam dyeing dyeing can not be dyed smoothly on the rope dyeing machine by using conventional equipment for denim.
The main reason is that the ball warping machine cannot realize that each yarn is wound into a b

Embodiment 1

[0071] Embodiment 1: a kind of viscose filament:

[0072] The filaments in this application can be prepared using existing technologies. As an example but not a limitation, this embodiment provides a cellulose filament, the preparation process of which includes:

[0073] 1) Preparation of spinning solution: add the cleaned and dried waste viscose fabric crumbs to a certain amount of dimethylacetamide DMAc solvent, treat at 160°C for 30min under a nitrogen atmosphere, then cool to 100°C, add pre- Weighed LiCl, then stirred continuously at 80°C for 30min until the cellulose was completely dissolved; since the obtained cellulose solution contained impurities and air bubbles, a transparent cellulose solution was obtained through filtration and defoaming treatment, and the mass fraction of cellulose in it was is 3%, the mass fraction of LiCl is 8%;

[0074] 2) Spinning: feed the cellulose solution into the metering pump, adjust the extrusion parameters, and directly enter the coag...

Embodiment 2

[0075] Embodiment 2: a kind of filament denim:

[0076] First, this embodiment provides a color fixing agent solution composition, which is prepared by the following steps:

[0077] 1) Ultrasound-assisted and at a temperature of 55°C, slowly add an aqueous solution of iron salt dropwise to an aqueous solution of 1,10-phenanthroline, and stir for 25 minutes with ultrasonic assistance;

[0078] 2) Maintain the temperature in step 1), slowly add tannin solution to the mixed solution in step 1), adjust the pH to 5.2 with acetic acid solution after stirring for 30 minutes, and ultrasonically assist stirring for 60 minutes;

[0079] 3) The mixed solution in step 2) was cooled to room temperature, followed by adding carboxymethyl cellulose hydrogel and halogenated pyridyl ketone compound, stirring at room temperature and constant speed for 60 min, and adjusting the pH to 6.8 with formic acid solution.

[0080] The preparation steps of the above color-fixing agent solution compositio...

Embodiment 3

[0107] Example 3: Another filament denim:

[0108] This embodiment provides another kind of filament denim, its formula and preparation process are basically the same as in Example 2, the difference is that in this embodiment, when preparing the color fixing agent solution composition, the halogenation in step 3) The pyridyl ketone compound is the compound 2-chlorophenyl pyridyl ketone in the form of formula (1b); and the filament denim is prepared according to the process of Example 2 by using the filament described in Example 1.

Abstract

The invention relates to the technical field of textile, and particularly relates to a production technology of novel cotton polyester denim. The production technology comprises the following steps: 1, spooling: spooling cellulose filament cop; 2, beaming; 3, dyeing: putting a warp beam on which filaments are wound on a beam dyeing machine ball warp frame via a shaft core device, and gathering yarn sheets via a guide roller and a ceramic ring into a bundle to enter a yarn guide ring for dyeing, wherein a dye vat includes indigo blue and a fixer solution composition of the invention; 4, sizing;5, weaving: weaving is completed by using Picanol rapier loom as a loom and using cotton-elastane dual-core elastic yarn as weft; 6, after-finishing; and 7, checking finished products. Color fastnessof the dyed fabric is effectively reduced, the utilization rate of the dye is reduced, the cost is lowered, damage to the brightness and color of the filaments is reduced, meanwhile, the moisture absorbing and re-adhesion phenomenon after the warp is sized can be significantly reduced, moisture absorption of the warp is reduced, the warp is insensitive to environment humidity, the surface is brighter and cleaner and has less pores, and the denim is beautiful in color, and also has gloss of the silk fabric and elegant hanging feeling.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a production process of novel filament denim. Background technique [0002] Cellulose is currently the largest renewable resource on the planet. It has the characteristics of low price, light weight, and biodegradability. It is an ideal green and environmentally friendly material. In modern life, the application of cellulose has not only stayed in the traditional textile and clothing and pulp and paper fields, but has been widely used to make various fiber-reinforced composite materials, and has been applied in many important structures. The characteristics of high specific strength, large specific stiffness and designable material properties make cellulose fiber reinforced composites one of the most promising new structural materials. Cellulose filaments are widely used in the fields of knitting and silk weaving. They are only used on weft yarns in denim. Cellulose filaments s...
