Embodiment 1

[0026] The present embodiment is a tube dyeing process of elastic velvet feather yarn, comprising the following process steps:

[0027] 1) Yarn preparation steaming: Steam the elastic velvet feather yarn from the textile factory at high temperature, the steaming temperature is 150-160°C, and the steaming time is 7-8 minutes, so that the yarn is pre-shrunk and soft and moist ,spare.

[0028] 2) Winding: the elastic velvet feather yarn steamed in step 1) is wound on the dyeing cylinder along the direction of the feathers, and the direction of the winding of the feathers is from the small end to the large end of the dyeing cylinder; The density is 0.35~0.37g / m 3 , The winding density arm pressure and tension are determined through multiple tests.

[0029] 3) Cage loading: put the bobbin wound in step 2) into the sarong from bottom to top, and the big end of the bobbin is downward and the small end is upward, and the connection between the upper bobbin and the lower bobbin is ac...

Embodiment 2

[0038] Three groups of elastic velvet feather yarns dyed in Example 1 were taken, and performance tests were carried out respectively, including the measurement of inner, middle and outer color difference, the measurement of fastness to rubbing and the measurement of fastness to washing. Among them, the measurement of inner, middle and outer color difference is evaluated according to the grade 5 evaluation standard of gray sample card; the test of fastness to rubbing is measured according to the provisions of GB / T3920-2008, and the test of fastness to washing is carried out according to the provisions of GB / T5703-1997 To measure. The results are shown in Table 1, where Level 5 is the best and Level 1 is the worst.

[0039] Table 1. Embodiment 1 gained elastic velvet feather yarn performance

[0040]

[0041]It can be seen from the above that the various performance indexes of the elastic velvet feather yarn dyed in Example 1 all reach the best. It overcomes the problem of...

Abstract

The invention discloses a bobbin dyeing process of an elastic velvet feather yarn. The process comprises ten steps including yarn preparation and steaming, winding, cage loading, boiling, cleaning, dyeing, color fixing, dewatering and drying, color inspection and the like. The physical and chemical characteristics of a velvet yarn and a feather yarn are comprehensively considered, and the featheryarn is shrunk first through yarn preparation and steaming to be soft and moist, so that winding is convenient. During winding, feathers of the feather yarn are wound from small ends to large ends, sothat dip dyeing in a dyeing solution is facilitated without depositing the dyeing solution in the included angles of the feathers. During dyeing, a double-stage slow heating strategy is adopted, theheating time and the dip dyeing heat preservation time are prolonged, and correspondingly bobbin yarn is fully immersed in a color to ensure that dyeing is uniform and full. After dyeing is finished,color inspection is carried out, and the dyeing degree is more accurate; reworking is not required in the middle of dyeing, so that the standardized time flow in the dyeing process and the dyeing timetemperature node control are ensured, current production is facilitated, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a tube dyeing process, in particular to a tube dyeing process for elastic velvet feather yarn. [0002] technical background [0003] Velvet is the name of the silk fabric in which loops or fluff are formed on the surface of the fabric by the velvet. It is also called Zhang Velvet. It is named after it originated in Zhangzhou, Fujian Province, China. The fluff or pile loops are densely erected, the color is elegant, the fabric is firm and wear-resistant, not easy to fade, and has good resilience and elasticity. Feather yarn is a fancy thread that has emerged in the domestic market in recent years. Its structure is composed of core thread and decorative thread, and the feathers are arranged in a certain direction. Nylon and viscose are used as raw materials, the fabric feels thick and durable, and the pile fabric made of it can keep plump and upright, and has good bulkiness and gloss. The elastic velvet feather yarn obtained by...
