Problems solved by technology

[0004] The current fabric ring seam seam line is 21 S / 6, the sewing thread is thick, and the circular seam head is large, which is easy to produce joint marks
The tension during rolling is generally relatively large, and at the same time, there will be a slow shrinkage in the process of cold pad batch dyeing and stacking, which will also squeeze the seam head greatly, and it is easy to produce joint marks. In severe cases, a seam head will be produced. Several circles of joint marks, fabrics with obvious joint marks can only be treated as substandard products

Abstract

The invention discloses a preparation method of an alkali-free cold pad-batch dyed antibacterial skin-care fabric. The preparation method comprises the main production process flow with the following steps of: turning and sewing, singeing with two front surfaces and one back surface, padding amylase for piling and desizing, scouring and bleaching with a scouring and bleaching machine, mercerizing with a full straight roller mercerizing machine, dyeing with alkali-free cold pad batch, performing one-bath finishing with a formaldehyde-free shrink-proof and hyaluronic acid finishing agent, calendering with a three-roller calendering machine, mechanically preshrinking, and inspecting and packaging. According to the preparation method of the alkali-free cold pad-batch dyed antibacterial skin-care fabric provided by the invention, a quaternary ammonium type cation modified cotton / cotton (70 / 30) blended wide woven fabric dyeing process is designed, reactive dye reacts with about 1 / 3 cations on the fabric, about 2 / 3 free quaternary ammonium type cations exist in the fabric, and the quaternary ammonium type cations have high antibacterial property. The hyaluronic acid finishing agent has moisturizing and skin-nourishing performance, so that the product has antibacterial and skin-care functions.

Description

technical field [0001] The invention relates to an alkali-free cold pad-batch dyeing antibacterial skin care fabric dyeing and finishing process, in particular to a cationic modified cotton and cotton blended wide-width woven fabric, which is smooth and crease-free with a straight-roller mercerizing machine, and the color difference between front and back is ≧4 Dyeing and finishing technology of non-alkali cold pad-batch dyeing, formaldehyde-free anti-shrinkage and hyaluronic acid finishing agent in the same bath for antibacterial skin care fabrics. Background technique [0002] When cationic modified cotton and cotton blended wide-width woven fabrics are mercerized on a straight-roll mercerizing machine composed of a conventional straight-roll alkali dipping area, a straight-roll alkali-removing area, and a flat washing machine, the width of the fabric in the weft direction is not wide enough. The width of the falling cloth is smaller than the lower limit of the width of th...
