Embodiment 1

[0025] This example provides a short-process pre-processing method for cotton, rayon, polyester and spandex blended woven fabrics. The blended woven fabric used is 65% cotton 31% rayon 2% polyester 2% spandex twill. The treatment process is followed by padding cold pile liquid (rolling residual rate 100%, two dip two rolling), cold pile (cold pile at room temperature for 24 hours), first washing, padding steaming liquid (rolling residual rate 100% , Two soaking and two rolling), steaming, second washing and drying 7 steps. Specific steps are as follows:

[0026] (1) Pad cold pile liquid:

[0027] The preparation of cold reactor liquid: add 25g / L of caustic soda, 20g / L of scouring enzyme, 3g / L of complexing agent, 28g / L of 50% hydrogen peroxide, and 10g / L of hydrogen peroxide stabilizer into the trough. The scouring penetrant is 5g / L. After each ingredient is added, it needs to be stirred evenly to prepare a cold pile liquid. The fabric to be treated is dipped into the cold pile...

Embodiment 2

[0041] This example provides a short-process pre-processing method for cotton, polyester and spandex blended woven fabrics. The blended woven fabric used is 65% cotton 33% polyester 2% spandex twill fabric. The short-process pre-treatment process is followed by padding. Cold pile liquid (rolling residual rate 100%, two dip two rolling), cold pile (cold pile at room temperature for 24 hours), the first water washing, pad steaming liquid (rolling residual rate 100%, two dip two rolling), 7 steps of steaming, second washing and drying. Specific steps are as follows:

[0042] (1) Pad cold pile liquid:

[0043] The preparation of cold reactor liquid: add 25g / L of caustic soda, 20g / L of scouring enzyme, 3g / L of complexing agent, 28g / L of 50% hydrogen peroxide, and 10g / L of hydrogen peroxide stabilizer into the trough. The scouring penetrant is 5g / L. After each ingredient is added, it needs to be stirred evenly to prepare a cold pile liquid. The fabric to be treated is dipped into the...

Embodiment 3

[0057] This example provides a short-process pre-treatment method for cotton, rayon and spandex blended woven fabrics. The blended woven fabric used is 78% cotton, 20% rayon, 2% spandex twill, and its short-process pre-treatment process passes through Pad cold pile liquid (rolling residual rate 100%, two dip two rolling), cold pile (cold pile at room temperature for 24 hours), the first water washing, pad steaming liquid (rolling residual rate 100%, two dip two rolling) ), steaming, second washing and drying 7 steps. Specific steps are as follows:

[0058] (1) Pad cold pile liquid:

[0059] The preparation of cold reactor liquid: add 25g / L of caustic soda, 25g / L of scouring enzyme, 3g / L of complexing agent, 28g / L of 50% hydrogen peroxide, and 10g / L of hydrogen peroxide stabilizer into the trough. The scouring penetrant is 5g / L. After each ingredient is added, it needs to be stirred evenly to prepare a cold pile liquid. The fabric to be treated is dipped into the cold pile solut...

Abstract

The invention provides a short-flow pretreatment processing method for a cotton blending woven fabric. Desizing, scouring and bleaching are carried out in one step after a singeing process. The method specifically comprises the following seven steps of dipping and rolling of a cold heap liquid, wherein the rolling rate is 100%, and a two-dipping and two-rolling mode is adopted; cold heaping; first water washing; dipping and rolling of a steaming liquid, wherein the rolling rate is 100%, and the two-dipping and two-rolling mode is adopted; steaming; second water washing; drying. According to the processing method, the traditional desizing, scouring and bleaching processes of the cotton blending woven fabric are realized by means of a one-step method, the process flow is shortened, the production efficiency is improved, and meanwhile the consumption of water, electricity and steam is reduced.

Description

Technical field [0001] The invention belongs to the technical field of printing and dyeing, and particularly relates to a short-flow pretreatment method for cotton blended woven fabric. Background technique [0002] Cotton fiber has good moisture absorption, warmth retention, and good compatibility with the skin. It can be blended with other fibers to form a variety of styles. It is loved by consumers and occupies an extremely important position in textile fabrics. The pre-treatment process of cotton blended woven fabric has three steps of desizing, scouring and bleaching. Generally, the combined method of steps such as desizing + bleaching and desizing + scouring and bleaching and one step desizing, scouring and bleaching method can shorten the pretreatment process. purpose. In addition, in order to meet people's diversified and differentiated requirements for the appearance, feel, elasticity and moisture absorption of fabrics, the early development of cotton fabrics or polyest...
