Description
Technical Field
The invention belongs to the technical field of dyeing and finishing, and relates to a preparation method of a double-sided cloth of acrylic fibers and plied polyester fibers, in particular to a preparation method of a double-sided cloth with superfine anti-pilling acrylic fibers and bulked acrylic fibers on the front surface and plied DTY polyester fibers on the back surface.
Background
The common cationic dye can dye acrylic fiber and modified terylene CDP, but cannot dye common terylene; the disperse dye can dye common terylene and cannot dye modified terylene CDP and acrylon. In the past, the acrylic fiber and the terylene want to be dyed by a one-bath method, the reverse side is usually modified terylene CDP, then the dyeing temperature is selected to be about 105 ℃, and the acrylic fiber and the CDP are dyed by cationic dye in one bath. The CDP price is higher than that of the common terylene, so that the cost is raised; and when the cationic dye is used for carrying out one-bath dyeing on the front acrylic fiber and the back CDP, the phenomenon of 'robbing color' of the acrylic fiber and the CDP exists, so that the color difference of the front side and the back side is large.
The reason why the above problems occur is that the cationic dye can dye the acrylic fibers on the front side and also can dye the modified terylene CDP on the back side, namely the cationic dye can dye the acrylic fibers on the front side and the modified terylene on the back side simultaneously in one bath of the dye vat so as to dye the acrylic fibers and the modified terylene CDP.
The main invention is the establishment of the dyeing process of acrylic fiber/common terylene by one bath process.
Disclosure of Invention
The invention aims to provide a method for preparing double-sided cloth of acrylic fiber and plied polyester fiber aiming at the problems in the prior art. The invention aims to solve the technical problem of how to dye acrylic fiber and common polyester by a one-bath method on the premise of not adopting modified polyester CDP.
The purpose of the invention can be realized by the following technical scheme: a preparation method of double-sided cloth of acrylic fiber and plied polyester fiber is characterized in that the preparation process is weaving → combined cylinder → one-bath dyeing polyester fiber and acrylic fiber → cotton covering → cylinder discharging and color matching → semi-finished product cloth arranging → drying → auxiliary agent adding and shaping → reverse side napping → reverse side combing → reverse side shearing → ring drying → final shaping → physical testing → finished product inspection → optical blank warehousing;
wherein, the front side of the double-sided cloth fabric is anti-pilling acrylic fiber, bulk acrylic fiber and viscose, and the back side of the double-sided cloth fabric is plied terylene;
the process for dyeing the terylene and the acrylon in one bath comprises the following steps: the positive anti-pilling acrylic fibers and the positive bulk acrylic fibers are dyed by adopting a cationic dye, common terylene is dyed by utilizing a disperse dye, and the cationic dye and the disperse dye are used for respectively dyeing two surfaces of double-sided cloth in one bath by selecting proper temperature conditions.
Controlling the dyeing temperature to dye the acrylic fibers with the cationic dye, and dyeing the common polyester fibers with the disperse dye at the same temperature. The heating rate and the cooling rate are controlled, and the quality of the fabric is ensured. The dyeing process generally used in the past is: dyeing acrylic fibers with cationic dye at the dyeing temperature of about 97 ℃; the disperse dye is used for dyeing common terylene, and the dyeing temperature is about 130 ℃. This makes ordinary polyester and acrylic fibres incapable of being dyed in one bath.
The dyeing temperature is controlled to be between 120 ℃ and 125 ℃, the dyeing temperature is relatively high when the black dyeing is carried out, and the dyeing temperature is set to be 125 ℃; the dyeing temperature was relatively low when dyeing light, set at 120 ℃ and higher the color. Under the temperature condition, the cationic dye can dye acrylic fibers, and the disperse dye can also dye common terylene. The temperature rise needs to pass through a plurality of climbing stages, the conventional method of rapid temperature rise is changed during temperature rise, the temperature rise rate is controlled, the cationic dye in the dye vat can uniformly dye acrylic fibers, and the disperse dye can uniformly dye common terylene.
Specifically, at 40 ℃, adding a color light stabilizer and a dispersant aid into a cylinder, adding a cationic dye, and then adding a disperse dye; after the feeding is finished, the temperature is increased from 40 ℃ to 70 ℃ at the speed of 1 ℃/min, then the temperature is preserved for 20 minutes, then the temperature is increased to 85 ℃ at the speed of 0.5 ℃/min, the temperature is preserved for 10 minutes, then the temperature is increased to 95 ℃ at the speed of 0.5 ℃/min, the temperature is preserved for 10 minutes, finally the temperature is increased to the dyeing temperature at the speed of 0.7 ℃/min, the temperature is preserved for 60 minutes, finally the temperature is reduced to 60 ℃ at the speed of 1 ℃/min, and then the water is drained.
The dyeing temperature is 125 ℃ or 120 ℃, which is the highest temperature to which the dye is required to be heated when the fabric is dyed. The rate of temperature rise is the degree of temperature rise per minute of the dye vat after the dye is added to the dye vat. The cooling rate is the temperature of the dye vat which is reduced by every minute from the highest temperature. The 'color robbing' refers to that when the cationic dye in the dye vat is used for dyeing acrylic fibers in one bath, the cationic dye in the dye vat synchronously dyes modified terylene CDP, so that the acrylic fibers and the CDP compete for the cationic dye, and the 'color robbing' phenomenon occurs.
According to the process parameter range, the acrylic fibers on the front side are dyed by cationic dye, the common terylene on the back side is dyed by disperse dye, the cationic dye cannot dye the common terylene, and the disperse dye cannot dye the acrylic fibers. Therefore, the phenomenon of 'color robbing' cannot be generated, thereby avoiding the large color difference between the front side and the back side.
The error of the temperature rising rate and the temperature reducing rate within 5 percent of the parameters does not have obvious influence on the dyeing effect, and the heat preservation temperature is not easy to change.
