Description

Technical Field

[0001] The invention belongs to the technical field of fabric dyeing and finishing, and particularly relates to a method for preparing a printed dimensionally stable fleece fabric. Background Art

[0002] With economic development and the improvement of living standards, consumers' demands for fabrics are becoming more and more diversified. In addition to traditional functional demands such as comfort and durability, they have put forward higher requirements for fashion and aesthetics. As a unique fabric, the biggest feature of pile fabric is that a layer of short plush is formed on the surface. This plush layer gives the fabric a soft touch and unique visual effect. It is the existence of this plush layer that makes it more difficult to present the dimensional stability, surface structure and printed patterns of pile fabrics. With the continuous advancement of manufacturing technology, the printing process of pile fabrics has gradually become an important direction of research and innovation in the industry.

[0003] CN104562715A discloses a method for processing all-cotton flannel printed fabrics, including the following steps: weaving, pre-treatment of grey fabrics, scalding and mercerizing of the fabric surface, pre-setting by a setting machine, drying on a machine for active printing, steaming and washing for color fixation, setting with a bulking agent and a softener, pre-shrinking, and finished product inspection. The method ensures that the color paste penetrates into the fabric by adjusting the slurry process, and also ensures that the pattern will not be blurred due to too much penetration into the direction of the fluff fibers.

[0004] CN110117884A discloses a method for processing high-penetration heat transfer printing plush fabrics, which includes the following steps: combing of blanks, ironing of blanks, pre-shaping, printing, water softening, drying, pulling, combing, shearing, ironing and shearing of finished products, air washing (shaking) and shaping of finished products. The method uses a high-penetration heat transfer printing machine for heat transfer printing, which improves the penetration of dyes and enhances the clarity of patterns.

[0005] In the manufacturing of pile fabrics, it is often necessary to go through processes such as napping, combing, and polarizing to adjust the pile layer of the fabric to give it a better touch and visual effect. However, this series of processing techniques brings certain challenges to the manufacturing of pile fabrics with printing requirements. A series of mechanical treatments on the pile layer will change the direction and density of the pile, resulting in a deviation in the size of the pattern, and the size change is often uncontrollable.

[0006] Therefore, how to ensure the accuracy of pattern size while maintaining the unique appearance and feel of the fabric through refined process control is one of the current technical difficulties. Summary of the invention

[0007] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a method for preparing a pile fabric with stable printing size.

[0082] Example 4

[0083] This embodiment provides a method for preparing a printed dimensionally stable fleece fabric. Compared with Embodiment 1, the longitudinal density of the velvet fabric in step (1) is controlled to be 40 strands / 5 cm, and the rest is the same as Embodiment 1.

[0084] Example 5

[0085] This embodiment provides a method for preparing a printed dimensionally stable fleece fabric. Compared with Embodiment 1, the longitudinal density of the velvet fabric in step (1) is controlled to be 48 strands / 5 cm, and the rest is the same as Embodiment 1.

[0086] Example 6

[0087] This embodiment provides a method for preparing a printed dimensionally stable fleece fabric. Compared with Embodiment 1, the temperature of the shaping process before printing in step (2) is controlled to be 110° C., and the rest is the same as Embodiment 1.

[0088] Example 7

[0089] This embodiment provides a method for preparing a printed dimensionally stable fleece fabric. Compared with Embodiment 1, the temperature of the shaping process before printing in step (2) is controlled to be 150° C., and the rest is the same as Embodiment 1.

[0090] Example 8

[0091] This embodiment provides a method for preparing a printed dimensionally stable fleece fabric. Compared with Embodiment 1, the temperature for setting the auxiliary agent in step (4) is controlled to be 130° C., and the rest is the same as Embodiment 1.

[0092] Example 9

[0093] This embodiment provides a method for preparing a printed dimensionally stable fleece fabric. Compared with Embodiment 1, the temperature for setting the auxiliary agent in step (4) is controlled to be 170° C., and the rest is the same as Embodiment 1.

[0094] Comparative Example 1

[0095] This comparative example provides a method for preparing a printed fleece fabric. Compared with Example 1, the pre-printing shaping in step (2) is not performed, and the rest is the same as Example 1.

[0096] The printed fleece fabric prepared by the present invention maintains good printing dimensional stability and fabric effect. The printed fleece fabric prepared in Example 1 has a gram weight of 220 g / cm 3 The final pattern size is 177.2×179.7cm (width×height). Compared with the preset pattern, the size is stable. The fabric shaping effect of Examples 1-3 is good, the suede particles of the fabric are clear and full, and the hand feels crisp, soft and does not collapse.

[0097] Compared with Example 1, in Examples 4 and 5, the longitudinal density of the fabric is changed. The longitudinal and transverse densities are mainly set by overfeeding and setting the parameters of the width. If the longitudinal density is too much, the longitudinal dimension is too small and the gram weight increases. If the longitudinal density is too little, the longitudinal dimension will be too large. If the longitudinal dimension is too large, the loss will increase and the cost will increase. At the same time, if the longitudinal pattern is too large, the corresponding transverse dimension will be small and it will be difficult to meet the requirements of the pattern size; in Examples 6-7, the fabric is shaped before printing to ensure the printing effect. When the temperature is too low, the fabric is not completely shaped, and the fabric is prone to deformation during the subsequent printing process, affecting the printing effect. When the temperature is too high, the fiber component will be destroyed, the yarn crystallinity will become higher, and it will affect the napping style. At the same time, it will also affect the color and fastness of the printed base fabric; in Examples 8-9, the shaping temperature will affect the shrinkage and printing fastness of the fabric. When the shaping temperature is too low, the printing will be unstable and a shrinkage deviation problem will occur. When the shaping temperature is too high, the printing will also be unstable and the fabric will feel hard, affecting the touch and use. In comparative example 1, no shaping is performed before printing, and the stable horizontal and vertical density of the fabric cannot be guaranteed, and the printed pattern cannot be fixed, and the preset size cannot be achieved during the suede treatment, which makes it difficult to meet the use requirements.

[0098] In summary, the preparation process of the pile fabric provided by the present invention effectively controls the dimensional changes caused by the mechanical treatment of the pile layer of the pile fabric by performing a specific shaping process before and after the pile fabric is printed, so that the printed pattern of the pile fabric maintains good dimensional stability, and the pile fabric has a good pattern appearance and touch.
