Embodiment

[0027] Fabric fabric: width 206cm, 216g / cm 3 .

[0028] The dyeing and finishing process of the high-elastic hemp fabric provided in this embodiment includes a pre-treatment process, a dyeing process and a setting process, and the pre-treatment process includes an open-width desizing process and a cylinder training process in sequence. , pre-setting process and loose alkali reduction process, the specific steps of the dyeing and finishing process are as follows:

[0029] (1) Pretreatment process:

[0030] In the open-width desizing process, an open-width desizing machine is used to desizing the gray fabric. The formula of the desizing aid used in the open-width desizing process is as follows:

[0031] Liquid caustic soda 45g / L,

[0032] Long car fast desizing agent TF-127HA 2g / L,

[0033] Sodium tripolyphosphate 2g / L;

[0034] The temperature conditions of the open-width desizing process are 85°C and the vehicle speed is 40m / min.

[0035] Under hot alkali conditions, com...

Abstract

The invention discloses a preprocessing technology for high-elastic habijabi fabric. The preprocessing technology sequentially comprises an open-width desizing process, a machine cylinder cloth manufacture process, a preforming process and a slack alkali decrement process, wherein the formula of a desizing assistant adopted for the open-width desizing process comprises the following components: 40to 60g / L of caustic soda liquid, 1 to 2g / L of a continuous rapid desizing agent TF-127HA, and 1 to 2g / L of sodium tripolyphosphate; the formula of a boiling off assistant for the machine cylinder cloth manufacture process comprises the following components: 25 to 30g / L of sodium carbonate, 1 to 2g / L of deoil agent TF, and 3 to 5g / L of hydrogen peroxide. Gray fabric subjected to machine cylinder cloth manufacture process treatment is subjected to preforming process through a preforming machine, and the preforming temperature is 200 DEG C; the gray fabric subjected to preforming is subjected toalkali decrement treatment by alkali liquor in the slack alkali decrement process, wherein the concentration of caustic soda liquid in the alkali liquor is 40g / L, and the treatment temperature is 95DEG C. A sizing agent, oil formulation and dirty marks on fabric can be effectively removed through reasonable design of the preprocessing technology, so that a cloth cover is smooth, the technology is beneficial to subsequent processing, the fabric is soft in hand feeling, and apparel application requirements are met.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a pretreatment process of a high-elastic hemp fabric before dyeing. Background technique [0002] In recent years, with the upgrading of domestic consumption and the advancement of science and technology, the market demand for elastic fabrics has gradually increased. In the process of production and use, the traditional elastic fiber spandex gradually exposed some problems, such as the dyeing and finishing temperature is too high, which may easily cause the loss of fabric elasticity; the yarn coating is not ideal, the spandex filaments are exposed, and the spandex fiber is not dyed and white Causes the presence of glowing spots on the fabric. Spandex fiber has gradually been unable to meet the current diversified industrial needs. Therefore, the research and development of spandex alternative and upgraded products has been widely carried out in sc...
