Problems solved by technology

Therefore, wool and polyester fabrics are often strip-dyed on PET polyester fiber and wool separately, and then mixed, spun, and weaved, which increases the energy consumption of dyeing and also increases the difficulty of dyeing process control.
[0004] Later, people began to try the one-bath dyeing process of this wool-polyester blended fabric. The wool-polyester blended fabric or the fabric with wool-polyester as the main component was dyed at a temperature lower than 108°C, usually around 95°C, to avoid Dyeing damages the performance of wool and saves cost at the same time, but the PET polyester fiber contained in it cannot achieve a complete dyeing effect, and the polyester fiber is prone to fading when the fabric is washed, and even stains the wool fiber
Subsequently, people developed cationic dyeable modified polyester under normal pressure; it was also found that the dyeing temperature of cationic dyeable modified polyester fiber still needs to be 115-120°C, which exceeds the temperature of wool, and cannot completely solve the existing technical problems
In addition, by increasing the molecular chain flexibility of PET polyester fiber, people have obtained normal pressure dyeable modified polyester with disperse dyes, but its blended fabric with wool is suitable for light-color dyeing, and dark-color dyeing is prone to staining of disperse dyes on wool , and the amount of dye required is large, and the residual dye content in the bath after dyeing is high, resulting in waste of dye; the dyeing temperature is as high as 70°C, and it needs to be kept at about 108°C, which consumes energy and will also damage wool.

Embodiment 1

[0031] Fabric of the present invention is manufactured through the following steps:

[0032] S1. Ingredients: 60S combed short hair, 66S combed short hair and 70S loose wool, 30D / 18F Newtron PBT elastic silk fiber with a length of 38mm after treatment with the treatment liquid according to 18%, 33%, 20%, and 29% weight percentages are weighed and mixed;

[0033] S2. Spinning: including opening and mixing in a wool machine, opening and removing impurities with a cleaning machine, carding with a carding machine to obtain wool tops, and using wool tops to go through a drawing frame for head and second combination to obtain evenly mixed yarns. Wool tops, carding, spinning, automatic winding, and yarn discharge of wool tops with an air spinning machine;

[0034] S3. Weaving: using middle rapier weaving, including warping, stringing, reeding, weaving, blank inspection;

[0035]S4. Finishing: including raw repair, bag sewing, initial washing, shrinking, rewashing, piece dyeing, dry...

Embodiment 2

[0041] The difference from Example 1 is that in this example, in the step S1 batching process, the 60S combed noil, 66S combed noil and 70S loose wool, length 120 mm 20D / 10F Newtron PBT elastic silk fibers are weighed and mixed according to the weight percentages of 15%, 15%, 40%, and 30%; 0.5% of fiber weight, disperse dye addition amount is 8% of PBT elastic silk fiber weight, bath ratio is 1:40, the pH value of the bath liquid is adjusted to 4 with acetic acid-sodium acetate, and the dyeing temperature is 45°C. Incubate at 100°C for 60 minutes.

Embodiment 3

[0043] The difference from Example 1 is that in this example, in the step S1 batching process, the 60S combed noil, 66S combed noil and 70S loose wool, length 30mm The 75D / 36F Newtron PBT elastic silk fibers are weighed and mixed according to the weight percentages of 45%, 45%, 9.9%, and 0.1%, respectively.

Abstract

The invention relates to a high-color-fastness wool-polyester blended fabric. The high-color-fastness wool-polyester blended fabric is formed by blending raw materials, namely, wool fiber and PBT stretch yarn fiber. The finished product is composed of, by weight, 70% to 99.9% of the 60 S to 70 S wool and 0.1% to 30% of the 20-75 D / 10-36 F PBT stretch yarn fiber. Compared with a traditional wool-polyester blended fabric, the high-color-fastness wool-polyester blended fabric has the advantages that the color fastness of the finished product is increased by about one level, energy and dyes are saved in the dyeing process, cost is saved, and great benefits are obtained.

Description

technical field [0001] The invention relates to the field of textile fabrics, in particular to a wool-polyester blended fabric with high color fastness and a manufacturing method thereof. Background technique [0002] The existing wool-polyester blended fabric uses ethylene terephthalate (PET) as the polyester fiber, which not only maintains the texture of wool, but also takes advantage of the high rigidity of PET polyester fiber. It is currently the most popular blended woolen fabric. Kind of welcome. But there is the shortcoming that dyeing process is complicated in existing this wool polyester blended fabric. [0003] Due to different structures and properties, the dyeing conditions of wool and PET polyester fibers are different: wool is usually boiled with acid dyes, and high temperatures exceeding 108°C will cause felting and hydrolysis of wool, which will damage the style and strength of the fabric; while PET polyester fibers Fibers need to be dyed with disperse dyes...
