Finishing technology of warp and weft cotton wrapped spandex four-way-stretch easy-care yarn-dyed fabric

Abstract

The invention discloses a finishing technology of a warp and weft cotton wrapped spandex four-way-stretch easy-care yarn-dyed fabric, and relates to a finishing technology of a cotton type elastic easy-care fabric. The technology comprises the steps of singeing, desizing, mercerizing, washing, preshrinking, high-temperature setting, easy-care finish and baking. An ordinary yarn-dyed fabric production route is changed in the technology process, wherein washing is conducted after mercerizing is conducted, and then sufficient alkali removing can be guaranteed; preshrinking is conducted directly,it is guaranteed that large enough elasticity is achieved in the radial direction. Accordingly, it can be guaranteed that the warp and weft cotton wrapped spandex four-way-stretch easy-care yarn-dyedshirt fabric is produced smoothly, a shirt is made by adopting the warp and weft cotton type elastic easy-care fabric, when people do body movement, limitation does not exist in the four directions, and people feel comfortable and free when wearing the shirt; due to the fact that elastic yarns exist in four directions, after deformation, the elastic yarns can return to the original position, and the aesthetic feeling of being neat in shape is guaranteed.

Description

technical field [0001] The invention relates to a post-finishing process for elastic cotton-type non-ironing fabrics. Background technique [0002] The cotton-type elastic non-ironing shirt fabric currently produced is cotton in the warp direction and cotton-wrapped spandex in the weft direction. [0003] The wearability of shirts made of this fabric is not good, especially when the body is active, such as: when writing or typing on a computer, when the arms are moving, or when the chest is stretched, etc., because only the weft direction is elastic, but the warp direction is not elastic. Influenced by the limitations of the body, the stretching back and forth, the stretching of the human body is restricted, and it feels uncomfortable and uncomfortable. Or, because the human body itself is uncomfortable, when excessive force is applied during the stretching process, the clothes will be deformed, and the warp direction cannot return to the original position due to lack of el...

Problems solved by technology

[0003] The wearability of shirts made of this fabric is not good, especially when the body is active, such as: when writing or typing on a computer, when the arms are moving, or when the chest is stretched, etc., because only the weft direction is elastic, but the warp direction is not elastic. Influenced by the limitations of the body, stretching back and forth, the stretching of the human body is restricted, and it feels uncomfortable and uncomfortable

Or, due to the discomfort of the human body, when excessive force is applied during the stretching process, the clothes will be deformed, and the warp direction cannot return to the original position due to the lack of elasticity.

[0004] In order to develop new products, we tried to produce cotton-wrapped spandex non-ironing shirt fabrics in both warp and weft directions, but the finishing process of this product was high in tension, resulting in no elasticity in the warp direction; and the spandex in the weft direction needed high temperature setting to stabilize the width of the fabric. , the high temperature setting results in less elasticity in the warp direction; the fabric needs to be finished with non-ironing, and the baking production after non-ironing requires high temperature, and the elasticity of the warp direction cannot be guaranteed, and normal production cannot be performed
