Description

A kind of air layer fabric and dyeing method thereof

technical field

The invention relates to the field of fabrics and their processing, in particular to an air layer fabric and a dyeing method thereof.

Background technique

Air layer fabrics include polyester, polyester spandex, polyester-cotton spandex, etc., which have become more popular in recent years due to their good warmth retention effect, no wrinkle, crisp and natural fabric, and fluffy hand feeling.

The air layer fabric usually includes an inner layer, a middle layer and an outer layer, and the inner layer and the outer layer are connected together through the middle layer. The air layer fabric can be made into positive and negative same-color fabrics and positive and negative different-color fabrics. For polyester spandex positive and negative different color fabrics, when the front of the fabric is woven with cationic polyester yarn and spandex, and the reverse side is woven with cationic polyester composite yarn (or cationic polyester yarn and ordinary polyester yarn) and spandex, the fabric is cationic dyed Finally, it can form the effect of solid color on the front and heather gray on the back, so as to achieve different colors on the front and back. When weaving this kind of fabric, the middle layer is usually made of thin ordinary polyester yarn. Due to the different coloring properties of ordinary polyester yarn and cationic polyester yarn, that is, when dyeing cationic polyester, ordinary polyester cannot be colored. When dyeing ordinary polyester, the coloring effect of cationic polyester and ordinary polyester is also different. The ordinary polyester yarn of the first layer will inevitably be exposed on the front or back of the fabric, which leads to the fact that after the fabric is dyed, the exposed middle layer of ordinary polyester yarn will form a line on the fabric due to the inability to color or the difference in the coloring effect. A vertical stripe, and the darker the dyed color, the more obvious the contrast, which seriously affects the texture of the fabric. When using polyester dyed yarn instead of ordinary polyester yarn to weave the middle layer, due to the incomplete color spectrum of the existing dyed yarn, when dyeing cationic polyester, only when the color dyed on the front side is consistent with the color of the intermediate dyed yarn, vertical stripes will not appear , which causes the air layer fabric to be unable to be dyed any color. In addition, when ordinary polyester yarn and polyester dyed yarn are used as the middle layer, the fluffy feeling of the fabric is relatively poor.

The conventional dyeing process of the above-mentioned air layer fabric includes blank unwinding-open width washing-presetting-dyeing-finished product setting. Among them, open-width washing is to remove oil, and the washing temperature is 80~90°C. After washing and shrinking, polyester and spandex will undergo a large thermal shrinkage in washing. The pressure of the large upper and lower pressure rollers will eventually lead to a large drop in the thickness of the fabric after open-width washing, the fluffy feeling will become worse, and the width of the door will also become narrower. After pre-setting, the thickness of the fabric is basically fixed. In order to obtain a certain width, it is necessary to carry out stenter setting on the basis of narrowing the width, which will further reduce the thickness of the fabric, and the fluffy feeling of the fabric will become worse.

Contents of the invention

In view of the above problems, the present invention provides a kind of air layer fabric, which can solve the above-mentioned polyester spandex front and back different color air layer fabrics, because the middle layer usually uses ordinary polyester yarn, resulting in vertical stripes on one side of the fabric after dyeing, which affects Fabric texture, and the technical problem that the fluffy feeling of fabric is poor, for this the present invention also provides the dyeing method of air layer fabric.

Its technical scheme is as follows:

An air layer fabric, which includes an inner layer, a middle layer and an outer layer, the inner layer and the outer layer are connected together through the middle layer, the outer layer is woven by cationic polyester yarn and spandex, the The inner layer is braided by cationic polyester composite yarn and spandex, and the feature is that: the middle layer is braided by cationic polyester yarn.

It is further characterized by:

The first and fourth routes use cationic polyester composite yarn and spandex, the second and fifth routes use cationic polyester yarn and spandex, and the third and sixth routes use cationic Polyester Yarn.

The first road and the fourth road use 50D/72F cationic polyester composite yarn and 30D spandex, the second road and the fifth road use 50D/48F cationic polyester yarn and 30D spandex, and the third road And the sixth way uses 30D/24F cationic polyester yarn.

The width of the fabric is 1.2m-1.4m.

The grammage of the fabric is 260g/m ² -340 g/m ² .

The above-mentioned dyeing method for air layer fabrics is characterized in that it comprises the following steps: unwinding of white blank → pre-setting → deoiling of dye vat → dyeing → finalization of finished product.

It is further characterized by:

The process of the pre-setting and the finalizing of the finished product is to spray 6Kg steam on the surface of the fabric before entering the casing for shaping, and then enter the shaping machine, wherein the shaping temperature is 90 ° C ~ 120 ° C, and the machine speed is 16 m/min ~30m/min.

The process of deoiling the dyeing vat is as follows: the gray cloth is introduced into an L-type high-temperature and high-pressure overflow dyeing machine, and 2 g/L-3 g/L soda ash and 2 g/L-3 g/L oil-removing yarn agent are added at room temperature, /min ~2.5°C/min Heat up to 110°C and hold for 20 minutes, drain and wash with overflow water.

The dyeing process is as follows: enter water, heat up to 50°C, add 0.2 g/L-0.5 g/L glacial acetic acid, add high-temperature and high-pressure leveling agent Suparex K powder: 0.5 g/L-1 g/L, emulsifier: 0.5 g /L ～1 g /L, moisture absorption and quick-drying additive: 1 g /L ～3 g /L, add cationic dye after running for 10 minutes, and then raise the temperature to 135 at a heating rate of 0.5 ℃/min ～1.5 ℃/min ℃, keep warm for 50min.

The moisture-absorbing and quick-drying additive uses Huntsman moisture-absorbing and quick-drying additive HSD.

The sizing machine adopts a Monforts 10-section chassis sizing machine.

The beneficial effects of the present invention are:

The air layer fabric of the present invention uses cationic polyester yarn to weave the middle layer, so that when the cationic polyester yarn of the middle layer is displayed on the fabric, because it has the same coloring property as the cationic polyester yarn, the fabric can be avoided after being dyed. Vertical stripes appear, compared with using ordinary polyester yarn to weave the middle layer, the texture of the fabric is better, and because cationic polyester has better bulkiness than ordinary polyester, the fabric woven will also be more fluffy and thick; the dyeing method of the present invention , by pre-setting the gray cloth first, after the gray cloth is pre-shaped, the thickness and width of the fabric are basically fixed, and then when the oil is removed and washed, the thermal shrinkage of the fabric can be greatly reduced, so that the dyed fabric Thicker and fluffier with a better hand feel.
