Problems solved by technology

This method is rarely used due to the high price of additives and the difficulty of recovery.
In order to be able to dye rich colors, resin finishing agents are often added during dyeing, but after resin finishing, the rubbing fastness and sublimation fastness of polyester fibers decrease, and dye migration is prone to occur at high temperatures
Or use the carrier dyeing method for dyeing, but the biggest problem with the carrier dyeing method is the toxicity and odor of the carrier. The toxic carrier will have a great impact on the operators, and the dyeing wastewater will be discharged into the river, poisoning aquatic organisms an...

Embodiment 1

[0020] Example 1, such as figure 1 Shown, a kind of preparation method of modified polyester fancy style knitted fabric comprises the following steps:

[0021] In step A, the modified polyester fiber is selected for dyeing. The selected polyester fiber is 75D / 72F / 2 (DTY cationic 100%), and the 75D / 72F / 2 (DTY cationic 100%) is first dyed into the required different colors;

[0022] Step B, weaving the dyed 75D / 72F / 2 (DTY cationic 100%) and 105D spandex yarn into a color stripe rib structure through a double-sided thread transfer machine, wherein the odd-numbered needles are looped weaving structure loops, and the even-numbered needles are also Loop weaving structure loop;

[0023] Step C, draining the gray fabric into the water;

[0024] Step D, drying the fabric gray cloth;

[0025] Step E, performing resetting on the gray fabric, the resetting temperature is 130°C, the speed is 20m / min, and the overfeed ratio is 30%. Obtain a kind of modified polyester color striped rib ...

Embodiment 2

[0026] Example 2, such as figure 2 Shown, a kind of preparation method of modified polyester fancy style knitted fabric comprises the following steps:

[0027]In step A, the modified polyester fiber and spandex yarn are woven into an air layer structure through a multi-track double-sided circular weft machine. In the 6-way triangular structure, the 1st and 4th lines use 50D / 72F (DTY cationic 100%) polyester, The 1st route is the weaving structure cycle of float, tuck, tuck and float; the 4th route is the cycle of tuck, float, float and tuck weaving structure; the 2nd and 5th routes use 75D / 72F / 2( DTY cationic 100%) polyester, the 2nd and 5th roads are loop forming, looping, floating thread, floating thread weaving structure cycle, the 3rd and 6th roads use 75D / 72F / 2 (DTY cationic 100%) polyester and 30D spandex For silk blended yarn, the 3rd and 6th routes are all floating, floating, looping, and looping weaving structure cycles.

[0028] Step B, washing the gray fabric in ...

Embodiment 3

[0033] Example 3, such as image 3 As shown, a method for preparing a modified polyester fancy style knitted fabric includes the following steps: In step A, the modified polyester fiber and spandex yarn are woven into a horizontal jersey structure through a single-side thread adjustment machine , in the 6-way triangular structure, the 1st, 2nd, 4th, and 5th roads use 75D / 72F (DTY) polyester, the 1st road is the weaving structure cycle of floating thread, loop forming, tucking, and floating thread, and the 2nd road is forming Loop, floating thread, floating thread, floating thread weaving structure cycle, the 4th road is looping, floating thread, floating thread, tuck weaving structure cycle, the 5th road is floating thread, loop forming, floating thread, floating thread weaving structure Circulation, 38D / 36F / 2 (DTY cationic 50%J50) polyester and 40D spandex blended yarn is used in the 3rd and 6th routes, and the 3rd and 6th routes are all floating threads, floating threads, lo...

Abstract

The invention provides a preparation method of a modified polyester fancy style knitted fabric, and relates to a knitted fabric. The method comprises the following steps of step A, selecting modified polyester fiber or modified polyester fiber and Spandex filaments; weaving the materials into fabric blank cloth with undershirt cloth, sanding undershirt cloth, rib fabric, color rib fabric, terry fabric, flannelette or air layers through weaving equipment; step B, performing open-width water washing on the fabric blank cloth; step C, pre-shaping the fabric blank cloth; step D, performing pretreatment on the fabric blank cloth; step E, dyeing the fabric blank cloth through cationic dyeing agents; step F, drying the fabric blank cloth; step G, re-shaping the fabric blank cloth. Compared with the existing product, the modified polyester fabric produced by the method has the advantages that the styles are various; the colors are vivid and rich; the performance achieves long effect and stability; the color fastness is good; the color dyeing is uniform; the functions of moisture absorption and fast drying, fuzzing and pilling resistance, static electricity resistance and the like are also achieved; in the production process, the energy consumption is low; the consumption of auxiliary agents is low; the cost is low; the fabric belongs to an environment-friendly fabric.

Description

technical field [0001] The invention relates to a knitted fabric, in particular to a modified polyester fancy-style comfortable fabric. Background technique [0002] Polyester fiber is a hydrophobic synthetic fiber. Due to the particularity of the chemical structure of ordinary polyester fiber polymers, polyester fiber lacks functional groups that can combine with direct dyes, acid dyes, basic dyes, etc., although it has the ability to form hydrogen bonds with disperse dyes. Ester-based, but the molecular chain structure of polyester is tight, and the dye molecules are not easy to enter the fiber, which makes dyeing difficult. Therefore, the dyeing of polyester fabrics needs to be done under high temperature and high pressure conditions (120 ° C ~ 130 ° C) or hot melt conditions (180 ° C ~ 220 ° C). ℃) for dyeing, the energy consumption is very large. But even if it is dyed at high temperature, polyester fiber can only be printed and dyed with some ordinary colors, the colo...
