Steaming preshrinking mechanism for eliminating potential shrinkage of textile fabric

Abstract

The invention provides a steaming preshrinking mechanism for eliminating potential shrinkage of a textile fabric, and relates to the field of textile fabric device.The steaming preshrinking mechanism for eliminating potential shrinkage of the textile fabric comprises a box body, a cloth inlet is formed in the left side of the box body, a cloth outlet is formed in the right side of the box body, and two hump plates are arranged at the top of the inner wall of the box body; a conical block is arranged at the bottom of the inner wall of the box body and located between the two hump plates. According to the steaming preshrinking mechanism for eliminating the potential shrinkage of the textile fabric, a W-shaped preshrinking channel is formed by arranging a hump plate and a conical block, water in a water tank is transpired to generate water vapor through cooperation of a heat pipe, the water tank and a first cavity, the water vapor is gathered above the conical block, and therefore steaming preshrinking treatment is conducted on the fabric. And hot air flow in the heat pipe flows out of the first cavity to preheat the cloth, so that the preshrinking speed is increased, and the preshrinking effect is improved. And through cooperation of the movable assembly, the influence of the drawing force on steaming preshrinking is reduced, and the situation that the preshrinking quality is influenced due to the fact that the drawing force borne by the cloth is too large is avoided.

Description

technical field [0001] The invention relates to the technical field of textile fabric equipment, in particular to a steam pre-shrinking mechanism for eliminating potential shrinkage of textile fabrics. Background technique [0002] In the production process of modern clothing, textile fabrics need to be pre-shrinked. Under certain temperature, humidity and pressure conditions, it can eliminate the potential shrinkage share of clothing fabrics by means of the elastic shrinkage deformation of the fabric itself and the principle of penetration and swelling of fabrics and fibers. [0003] For this purpose, a fabric pre-shrinking machine, also known as a shrinking machine, is used. The pre-shrinking machine can be used for pre-shrinking of pure cotton, chemical fiber, blended fabrics and woolen fabrics. [0004] However, when the traditional pre-shrinking machine pre-shrinks the textile fabric, the pre-shrinking effect is not good due to the simple structure. [0005] In order...

[0004] However, when the traditional pre-shrinking machine pre-shrinks the textile fabric, the pre-shrinking effect is not good due to its simple structure.

[0005] In order to ensure the efficiency of pre-shrinking when pre-shrinking fabrics through steaming pre-shrinking machines, hot steam is sprayed on the fabrics in a moving state, and the pre-shrinking is completed when the hot steam is sprayed on the surface of the moving fabrics. The movement forms resistance, which causes a certain stretching force inside the fabric, which affects the quality of pre-shrinking
