Problems solved by technology

[0003] Existing sandwich fabrics have disadvantages such as poor fluffiness, poor resilience, easy dust accumulation on the surface, and thready front and back.
[0004] Cotton fiber has the characteristics of moisture absorption, heat preservation, heat resistance, and alkali resistance, and has good comfort. However, due to the poor resilience of cotton fiber, it is rarely used in sandwich fabrics
[0005] The conventional dyeing temperature of polyester fiber is 130°C, but due to the existence of SORONA fiber and spandex fiber, this dyeing temperature not only consumes a lot of energy, but also causes serious staining of spandex, affects color fastness, and causes SORONA fiber to lose its elasticity.

Embodiment 1）

[0019] The upper fabric layer and the lower fabric layer of the cotton / polyester / ammonia / SORONA sandwich fabric of this embodiment are all interwoven by 95% cotton yarn+5% spandex yarn, and the middle layer is polyester / SORONA blended yarn.

[0020] The dyeing and finishing process of the cotton / polyester / ammonia / SORONA sandwich fabric of the present embodiment has the following steps:

[0021] S1: Scouring and degreasing, the temperature is 95℃, the time is 30min, the formula of scouring liquid is as follows: 1.0g / L scouring agent AP800, 1.5g / L scouring emulsifier SEM-35N, 2.0g / L spandex degreasing agent ST-1050 , 3.0g / L caustic soda and 5.0g / L hydrogen peroxide.

[0022] S2: Pre-forming, the temperature is 200°C, the vehicle speed is 20m / min, and the time is 3min.

[0023] S3: Staining.

[0024] S31: Dyed polyester.

[0025] Add the cotton / polyester / ammonia / SORONA sandwich fabric to the dyeing solution. In the first stage, the temperature is raised to 105°C at a heating r...

Embodiment 2～ Embodiment 3）

[0034] The cotton / polyester / ammonia / SORONA sandwich fabric of each embodiment is the same as that of Example 1, and the dyeing and finishing process is basically the same as that of Example 1, except that the heating rate of dyed polyester in step S31 is shown in Table 1 for details.

Abstract

The invention discloses a cotton / polyester / spandex / SORONA sandwich fabric and a dyeing and finishing process thereof. An upper fabric layer and a lower fabric layer of the cotton / polyester / spandex / SORONA sandwich fabric are both formed by interweaving cotton yarns and spandex yarns, and a middle layer is polyester / SORONA blended yarns; the dyeing and finishing process of the cotton / polyester / spandex / SORONA sandwich fabric comprises the steps of refining and oil removal, pre-setting, dyeing and finished product setting, wherein the dyeing comprises polyester dyeing and cotton dyeing, the polyester dyeing comprises three stages of heating, the heating rate of each stage is not more than 2.5 DEG C / min, the heating temperature of the third stage is 125+ / -3 DEG C, and the operation is carried out for 40-60 minutes. By means of the dyeing and finishing process, it can be guaranteed that the cotton / polyester / spandex / SORONA sandwich fabric is good in coloring depth and high in color fastness, meanwhile, the cotton / polyester / spandex / SORONA sandwich fabric has good hand feeling and filling power, the cloth cover is flat and free of wrinkles and basically free of creases, and energy consumption can be reduced.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a cotton / polyester / ammonia / SORONA sandwich fabric and a dyeing and finishing process thereof. Background technique [0002] The sandwich fabric consists of upper, middle and lower sides. The surface is usually designed with mesh, the middle layer is MOLO yarn connecting the surface and the bottom surface, and the bottom surface is usually a densely woven flat surface, commonly known as "sandwich". [0003] The existing sandwich fabrics have disadvantages such as poor fluffiness, poor resilience, easy dust accumulation on the surface, and thready front and back. [0004] Cotton fiber has the characteristics of moisture absorption, heat preservation, heat resistance, and alkali resistance, and has good comfort. However, due to the poor resilience of cotton fiber, it is rarely used in sandwich fabrics. [0005] The conventional dyeing temperature of...
