Problems solved by technology

However, in the process of dyeing and finishing, due to improper use of technology or parameters, the fabric is prone to chromatic aberration, uneven dyeing, scratches and polishes, crepe prints, and hard hand feeling. Therefore, choosing a suitable dyeing and finishing process determines the quality of the fabric. Dyeing quality and other properties, and the production process needs to be strictly controlled to ensure production quality

Embodiment

[0039] Fabric fabric: width 175cm, density 155g / m 2 .

[0040] The dyeing and finishing process of the memory T400 fabric based on the bio-based material of the present invention includes a pretreatment process, a dyeing process and a setting process carried out in sequence.

[0041] During the weaving process, the memory T400 fabric is subjected to high tension and friction in the warp direction, and is prone to breakage. In order to reduce breakage, improve weaving efficiency and gray fabric quality, warp yarns need to be sized. However, the size is beneficial to weaving but not conducive to dyeing and finishing. The size film covered on the surface will hinder the diffusion of dyestuffs into the fiber during the dyeing process. If impurities and dirt are not removed, it will not only affect the feel and color of the fabric, but also affect the hygroscopicity of the fabric, making the fabric color uneven, the color not bright, and affect the color fastness. Therefore, befo...

Abstract

The invention discloses a dyeing and finishing processing technique of memory T400 fabric based on a biological based material. The technique sequentially includes: pretreating, dyeing and shaping; the pretreating process sequentially includes: first-time open-width desizing, cold pad-batching and second-time open-width desizing, and a dyeing agent adopted in the dyeing process is composed of a dyeing aid and dye which is disperse dye; the dyeing process utilizes a high-temperature high-pressure liquid flow dyeing machine for dyeing, and the dyeing aid and the disperse dye are started to be injected respectively when temperature of a dyeing vat of the dyeing machine reaches 45 DEG C; the shaping process utilizes shaping treatment liquid to shape fabric greige cloth after being dyed througha shaping machine. By formulating proper pretreating, dyeing and shaping processes, processed fabric is enabled to be free of defects like crepe mark and scratch while dyeing quality is ensured, andthe fabric is endowed with high elasticity, memorability and additional functional function.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, in particular to a dyeing and finishing process of memory T400 fabric based on bio-based materials. Background technique [0002] With the crisis of non-renewable energy sources such as oil and natural gas and the escalating requirements for environmental protection review, resources and environmentally friendly materials have become the research and development focus of enterprises and research institutions in various countries. The transformation of renewable energy into production materials is of great significance to the current social development. Bio-based materials are a type of biopolymer materials or monomers obtained through biotransformation methods using renewable raw materials, and then further polymerized to form general-purpose polymer materials. Since the material is first biomodified, it is more environmentally friendly in terms of biocompatibility and biodeg...
