Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, specifically to a fabric drying and pre-shrinking device. Background Technology

[0002] In the fabric processing industry, drying and pre-shrinking is a crucial process. Its purpose is to stabilize fabric dimensions, reduce shrinkage during subsequent use or processing, and ensure the quality stability of fabric products. However, many fabric drying and pre-shrinking devices currently on the market have revealed numerous problems in actual operation.

[0003] Traditional fabric drying and pre-shrinking equipment typically uses a fixed conveyor structure. During the drying and pre-shrinking process, it cannot flexibly adjust the fabric tension according to the fabric's material, thickness, and actual processing requirements. When the fabric is conveyed too loosely in the equipment, wrinkles easily form. These wrinkles not only affect the uniformity of heating during the drying process, leading to over-drying in some areas and under-drying in others, thus reducing the overall quality of the fabric, but may also cause deformation during the pre-shrinking stage due to uneven stress, causing the fabric's dimensional deviation to exceed the standard range. Conversely, if the fabric is conveyed too tightly, for some highly elastic or fragile fabrics, such as elastic cotton or lace, excessive stretching may damage the fiber structure, causing the fabric to lose its original elasticity and toughness, reducing its strength, and making it prone to tearing during subsequent use. Therefore, we propose a fabric drying and pre-shrinking equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a fabric drying and pre-shrinking device with the advantage of adjustable tension. This solves the problem that traditional fabric drying and pre-shrinking devices typically use a fixed conveying structure, which cannot flexibly adjust the fabric tension according to its material, thickness, and actual processing requirements during drying and pre-shrinking. When the fabric is conveyed too loosely in the device, wrinkles easily appear. These wrinkles not only affect the uniformity of heating during the drying process, leading to over-drying in some areas and under-drying in others, thus reducing the overall quality of the fabric, but may also cause deformation during the pre-shrinking stage due to uneven stress, causing the fabric's dimensional deviation to exceed the standard range. Conversely, if the fabric is conveyed too tightly, for some highly elastic or fragile fabrics, such as elastic cotton or lace, excessive stretching may damage the fiber structure, causing the fabric to lose its original elasticity and toughness, reducing its strength, and making it prone to tearing during subsequent use.
