TECHNICAL FIELD
[0001] The utility model relates to the technical field of yarn stretching setting, specifically to a yarn stretching setting device. BACKGROUND
[0002] The main purpose of yarn stretching setting is to improve the physical properties and dimensional stability of yarn. Through stretching setting, the fibers inside the yarn can be arranged more neatly, reducing the sliding and friction between fibers, improving the strength and elongation of the yarn. At the same time, stretching setting can also eliminate the internal stress generated during the processing of yarn, preventing yarn from deforming and shrinking during subsequent use. Yarn stretching setting is an important process in textile processing. Through reasonable process parameters and equipment selection, the physical properties and dimensional stability of yarn can be significantly improved. Yarn stretching setting is widely used in the textile, clothing, leather and other industries. Through stretching setting, the physical properties and dimensional stability of yarn can be improved, and the quality and durability of fabric can be improved. At the same time, stretching setting can also be used for post-finishing processing of yarn, such as dyeing, printing, etc., to improve the added value and market competitiveness of yarn.
[0003] The prior art patent document CN2223302189U provides a yarn stretching setting device. The device sets a guide tube inside the setting furnace body, and the outside of the guide tube is wrapped with a heating coil. The initial heating setting can be completed in the guide tube. In addition, not less than one set of heating rollers is added in the setting furnace body. The yarn passes through the rollers and is subjected to secondary heating setting by the heating rollers. The heat setting effect is better, the heat setting efficiency is improved, and the dry shrinkage of the yarn is reduced.
[0004] However, in the prior art, the hot air blown by the air heater may not be evenly distributed, resulting in uneven heating of the yarn, affecting the setting effect. Long-term baking not only may cause over-heating, but also may cause energy waste and increase production cost. Therefore, we need a yarn stretching setting device. UTILITY MODEL CONTENTS
