Embodiment Construction

[0011] A formaldehyde-free, low-shrinkage, high-end memory lining, including the steps of weaving, steaming, finishing, and dot coating,

[0012] (1) When weaving, the amplitude is 49-50", ensure that the rear track is 43"-44" without strong pulling, and ensure the shrinkage in the weft direction;

[0013] (2) When finishing, use a formaldehyde-free cross-linking agent, and control the pH of the cloth surface during the pre-treatment to be the same as the pH value of the working fluid during the post-treatment, which is 4.0-5.0, and add a formaldehyde blocking agent to achieve the goal of formaldehyde-free; The processing adopts the loose processing method, and the shrinkage in the warp direction is controlled by stacking. During the post-processing, the loop overfeeding and the width control are carried out to ensure the shrinkage in the warp and weft directions again, and the rubber blanket is used for mechanical and physical extrusion. To eliminate the internal stress in the wa...

Abstract

The high grade lining cloth is produced through weaving in the width of 49-50'', steaming, finishing and spot painting. During the finishing, no-formaldehyde cross-linking agent is used, the pH value of the cloth during the preliminary treatment and that of the working liquid in the after treatment are controlled the same, 4.0-5.0, and formaldehyde blocking agent is adopted. The finishing includes the preliminary treatment in loose mode and the after treatment including cycling, overfeeding, width controlling and mechanical extruding. The spot painting adopts orthogonal optimizing combination method and uses glue powder with low flowability and easy painting. The present invention features no formaldehyde, low shrinkage and memory capacity.

Description

Technical field: [0001] The invention relates to an interlining cloth. Background technique: [0002] The existing interlinings generally have the problems of large formaldehyde content, large shrinkage rate, and no memory function, which affect their use effect. Summary of the invention: [0003] The purpose of the present invention is to provide a high-grade lining cloth with no formaldehyde pollution, good performance, no formaldehyde, low shrinkage and memory. [0004] The technical solution of the present invention is: [0005] A formaldehyde-free, low-shrinkage, high-end memory lining, including the steps of weaving, steaming, finishing, and spot coating, and is characterized by: [0006] (1) When weaving, the width is 49~50"; [0007] (2) When finishing, use formaldehyde-free cross-linking agent, and at the same time, control the pH of the cloth surface during the pre-treatment to be the same as the pH of the working fluid during the post-treatment, which is 4.0-5.0, and ...
