Problems solved by technology

Its shortcoming is that: after the fabric is immersed in the anti-ultraviolet finishing solution twice, the fabric immersed in the anti-ultraviolet finishing solution first will absorb a large amount of anti-ultraviolet finishing agent, resulting in a decrease in the concentration of the anti-ultraviolet finishing solution, so that the fabric will be adsorbed on the fabric in the direction of travel. The concentration of the anti-ultraviolet finishing solution decreases, which eventually leads to fluctuations in the anti-ultraviolet finishing effect in the length direction of the piece

Abstract

The invention relates to an attraction type anti-ultraviolet finishing method capable of achieving magnetic lifting of a bonding liquid for fabric and belongs to the technical field of textiles. A finishing liquid tank adopted in the method is hollow and is internally and movably provided with an iron bonding liquid plate, an electromagnet is fixedly arranged above the finishing liquid tank and corresponds to the iron bonding liquid plate, the surface area of the electromagnet is equal to that of the iron bonding liquid plate, the magnetic force of the electromagnet is in direct proportion tothe weight of the iron bonding liquid plate and the depth of the finishing liquid tank, and the electromagnet and a driving guide roller group are separately connected to a stroke controller. According to the finishing method, the fabric is not directly in contact with an anti-ultraviolet finishing liquid, and the phenomenon that the concentration of the anti-ultraviolet finishing liquid is changed since an anti-ultraviolet finishing agent in the flame-retardant finishing liquid is excessively adsorbed by the fabric cannot occur. Therefore, by adopting the technical scheme, the concentration of the anti-ultraviolet finishing liquid in an anti-ultraviolet finishing process is not changed, and convenience is provided for ensuring the consistency of the anti-ultraviolet effect of the fabric.

Description

technical field [0001] The invention relates to a fabric magnetic lifting liquid absorption type anti-ultraviolet finishing method, which belongs to the technical field of textiles. Background technique [0002] Ultraviolet rays can damage the color and mechanical properties of fabrics. In order to ensure the wearability of fabrics in an ultraviolet environment, anti-ultraviolet finishing has emerged as the times require. The common process of anti-ultraviolet finishing is padding finishing process. China's public publication "Silicate Bulletin", published in Volume 35, Issue 03, 2016, the title of the article is based on nano-TiO 2 -SiO 2 Composite particles prepare anti-ultraviolet superhydrophobic composite functional cotton fabric. This document introduces a fabric anti-ultraviolet finishing method. The finishing process is two dipping and two rolling, and the excess rate is 60%-70%. After the fabrics padded with anti-ultraviolet finishing agent are prebaked and baked...
