Problems solved by technology

Due to the characteristics of seaweed fiber and the high quality requirements of its products, this puts forward high requirements for the dyeing and finishing of seaweed fiber fabrics. At present, in the weaving and subsequent textile processing of seaweed fiber fabrics, due to the addition The presence of raw materials and oil stains has a great impact on the appearance, feel and dyeability of the fabric. Therefore, it is necessary to perform pretreatment for the purpose of removing impurities such as pulp and oil stains before dyeing and finishing. At present, seaweed The dyeing and finishing process of fiber fabrics includes pretreatment, dyeing, and finishing. Among them, the pretreatment process includes multiple processes such as desizing, scouring, and bleaching. The process flow is long, energy consumption is large, and wastewater pollution is serious. Therefore, how to optimize The pre-treatment process of seaweed fiber fabrics, combined with optimized dyeing and finishing processes, is the key to improving the quality of seaweed fiber fabrics

Embodiment Construction

[0023] The dyeing and finishing process steps of the seaweed fiber fabric of the present invention include: pretreatment-dyeing-after-finishing process, specifically as follows:

[0024] 1. Pretreatment

[0025] 1.1. Process flow: Enzyme-oxygen descouring and bleaching one-bath treatment process: immersion in processing fluid-boiling and bleaching (70-100°C, 30-60min)-hot water washing (80°C, twice)-cold water wash

[0026] 1.2. Put the fabric into the dyeing vat with a bath ratio of 1:5 to 1:30 at room temperature, add 1 to 3% of multifunctional scouring enzyme 10A type and 2 to 10% of hydrogen peroxide (27%) according to the weight percentage of the fabric, and then heat to Boil and bleach at 70-100°C, keep warm for 30-60 minutes, wash and prepare for dyeing.

[0027] 1.3. Pretreatment results and analysis of different process conditions

[0028] 1.3.1. Enzyme dosage

[0029] Carry out above-mentioned pretreatment test respectively by the enzyme consumption described in ...

Abstract

The invention discloses a dyeing and finishing technology for seaweed fiber fabrics, which belongs to the technical field of textile printing and dyeing. The dyeing and finishing technology comprises the following steps of pre-treatment, dyeing and after-treatment, wherein pre-treatment adopts the treatment technology of enzyme-deoxidized annealing and bleaching-bath method; and the fabrics are placed into a dye jar with a bath ratio between 1 to 5 and 1 to 30 at a normal temperature, added with an immersing working fluid, heated to a temperature of between 70 and 100 DEG C, bleached, subjected to heat insulation for 30 to 60 minutes, subjected to water scrubbing and standby for dyeing. The dyeing and finishing technology adopts the treatment technology of enzyme-deoxidized annealing and bleaching-bath method; the capillary effect of the fabrics is more than 10.5 centimeters; the brightness reaches more than 82; and the strength loss is less than 10 percent. The dyeing technology of one bath two stage process shortens the processing time for 50 percent, is energy-saving and reduces consumption.

Description

technical field [0001] The invention relates to a dyeing and finishing process of seaweed fiber fabrics, which can be applied to seaweed fiber fabrics and fabrics blended with seaweed fibers and other fibers such as polyester, polyester cotton and spandex, and belongs to the technical field of textile printing and dyeing. technical background [0002] Seaweed fiber is a new type of material made of alginate. Because seaweed fiber has biological activities such as hemostasis, anti-sticking, antibacterial and other friendly functions, its main use in textiles is to prepare wound covering materials. At present, the output value of wound dressing materials made of seaweed fiber has exceeded 2 billion US dollars in the world, so it is the main raw material of high-tech biomedical textiles. Due to the characteristics of seaweed fiber and the high quality requirements of its products, this puts forward high requirements for the dyeing and finishing of seaweed fiber fabrics. At pres...
