Description
Technical Field
The invention belongs to the technical field of textile printing and dyeing, and particularly relates to a cotton/polyester/ammonia/SORONA sandwich fabric and a dyeing and finishing process thereof.
Background
The sandwich fabric consists of an upper surface, a middle surface and a lower surface. The surface is usually a mesh design, the middle layer is MOLO yarn connecting the surface and the bottom surface, which is usually a tightly woven flat plate, commonly known as a "sandwich".
The prior sandwich fabric has the defects of poor fluffy feeling, poor rebound resilience, easy dust accumulation on the surface, silk flooding on the front side and the back side and the like.
The cotton fiber has the characteristics of moisture absorption, heat preservation, heat resistance and alkali resistance, and is good in comfort, but the cotton fiber is poor in resilience, so that the cotton fiber is rarely applied to the sandwich fabric.
The conventional dyeing temperature of the polyester fiber is 130 ℃, but due to the existence of the SORONA fiber and the spandex fiber, the dyeing temperature is high in energy consumption, the spandex is seriously stained, the color fastness is influenced, the SORONA fiber loses elasticity, and the hand feeling is influenced.
Disclosure of Invention
The invention aims to solve the problems and provides a cotton/polyester/ammonia/SORONA sandwich fabric and a dyeing and finishing process thereof, wherein the cotton/polyester/ammonia/SORONA sandwich fabric has the advantages of good coloring depth, high color fastness, good hand feeling, less crease marks on the fabric surface and low energy consumption.
The technical scheme for realizing the purpose of the invention is as follows: a cotton/terylene/ammonia/SORONA sandwich fabric is characterized in that an upper fabric layer and a lower fabric layer are both formed by interweaving cotton yarns and spandex yarns; the middle layer is terylene/SORONA blended yarn.
The dyeing and finishing process of the cotton/polyester/ammonia/SORONA sandwich fabric comprises refining and deoiling, presetting, dyeing and finished product setting.
The refining oil removal and the presetting are conventional methods aiming at cotton/terylene/ammonia fabrics in the field.
The dyeing comprises dyeing polyester and dyeing cotton.
The specific dyeing and washing method comprises the following steps: in the first stage, the temperature is raised to 105 +/-3 ℃ at the temperature rise rate of 1.5-2.0 ℃/min, and the operation is carried out for 10-20 min; in the second stage, the temperature is increased to 115 +/-3 ℃ at the temperature increase rate of 1.0-1.5 ℃/min, and the operation is carried out for 10-20 min; in the third stage, the temperature is increased to 125 +/-3 ℃ at the temperature increase rate of 0.5-1.0 ℃/min, and the operation is carried out for 40-60 min; in the fourth stage, the temperature is reduced to 60 +/-3 ℃ at a cooling rate of 1.0-2.0 ℃/min.
In order to reduce the cloth surface crease, the temperature rising rate cannot exceed 2.5 ℃/min.
The temperature rise temperature of the third stage of dyeing polyester is critical, and when the temperature is lower than 122 ℃, the polyester can be seriously decolorized, the dyeing depth is poor, and the color fastness is low; when the temperature is higher than 128 ℃, for example, the conventional dyeing temperature of the polyester fiber is 130 ℃, not only can the spandex stain seriously and the color fastness be low, but also the SORONA fiber loses elasticity and has a common hand feeling.
Reduction cleaning, acid neutralization, hot water washing and overflow washing are also included between the dyeing and washing and the dyeing cotton.
The cotton dyeing is a conventional cotton fiber dyeing method in the field.
In order to reduce the cloth cover crease, the finished product is shaped in a widening and shaping mode.
The invention has the following positive effects: the dyeing and finishing process can ensure that the cotton/polyester/ammonia/SORONA sandwich fabric has good coloring depth, higher color fastness, good hand feeling and fluffiness, smooth and wrinkle-free cloth surface and basically no crease, and can reduce energy consumption.
