Problems solved by technology

On the other hand, the film-like material sticks the yarns together, and the sticking of the yarns makes it difficult for the yarns to slide against each other when the fabric is subjected to an external force, which makes the fabric feel harder and the softness performance deteriorates, which affects the texture of the fabric. comfort
[0005] Chinese patent application publication number CN102041698A, the application publication date is May 4, 2011, the name of the invention is "a preparation method of luminous printed fabric", the application discloses a method to solve the fabric softness, using a tenter The mechanical external force will destroy the coating film that blocks the pores, which is beneficial to the mutual displacement of the yarns and the enhancement of the air permeability of the fabric. It will cause the film in some pores to fall off easily, which will affect the wearing performance of the fabric

Abstract

The invention relates to a method for improving the air permeability and softness of paint-dyed fabrics, in particular to a method for physically pretreating fabrics after padding dyeing solution before pre-drying to enhance fabric air permeability, which belongs to the field of textile processing. In the entire process of fabric E paint dyeing, a negative pressure suction device is installed between the fabric E pad dyeing solution and the pre-drying process, and the paint in the gaps and holes of the fabric is removed by negative pressure suction, and then the processed Fabric E is pre-dried, the pre-drying temperature is 80°C-100°C, and the pre-drying time is 5min-10min. The paint-dyed fabric E treated by this technical method can suck out the paint dye solution that affects the softness of the fabric E, reduces the mutual adhesion between the yarns, and the softness and air permeability of the fabric E are obviously improved.

Description

technical field [0001] The invention relates to a method for improving the air permeability and softness of paint-dyed fabrics, in particular to a method for physically pretreating the fabric after padding with paint dye solution before pre-drying so as to improve the air permeability and softness of the fabric. Textile processing field. [0002] technical background [0003] With the continuous improvement of people's living standards, the requirements for the performance of textiles are also getting higher and higher. Among them, the breathability and softness of textiles are one of the important indicators to measure the comfort performance of textiles. Under the condition of the same fiber type and yarn structure, the air permeability of the fabric depends on the porosity of the fabric. The pores in the fabric include straight-through pores and amorphous pores. Straight-through pores refer to the pores that penetrate from one side of the fabric to the other. Pores direc...
