Embodiment 1

[0023] (1) Stretching: The woven gray fabric is stretched to 10% wider than the required width by the tenter setting machine, about 30cm wider than the required width.

[0024] (2) One-time drying: the gray cloth after tentering is quickly dried at a temperature of 150°C, and the drying time is 60 seconds.

[0025] (3) Dyeing and finishing: Dyeing and finishing the dried fabric, and the temperature of the fabric entering the cylinder is controlled at 45°C.

[0026] (4) Secondary drying: Each piece of gray cloth after rapid drying is soaked in water separately and then dehydrated, and dried in a drum dryer at a temperature of 85°C for 30 minutes to make it 70% dry. After finishing the fabric, prevent the fabric from knotting into surface defects, and then dry it again for 5 minutes to straighten the fabric.

[0027] (5) Shrinking finishing: The dried fabric is processed by a shrinking machine at a temperature of 120°C for 20 seconds to keep the fabric stable and flat.

Embodiment 2

[0029] (1) Stretching: The woven gray cloth is stretched to 15% wider than the required width by the tenter setting machine, about 50cm wider than the required width.

[0030] (2) One-time drying: the gray cloth after tentering is dried quickly at a temperature of 180°C, and the drying time is 45 seconds.

[0031] (3) Dyeing and finishing: Dyeing and finishing the dried fabric, and the temperature of the fabric entering the cylinder is controlled at 55°C.

[0032] (4) Secondary drying: Each piece of gray cloth after rapid drying is soaked in water separately and then dehydrated, and dried in a drum dryer at a temperature of 95°C for 10 minutes to make it 70% dry. After finishing the fabric, prevent the fabric from knotting into surface defects, and then dry it again for 10 minutes to smooth the fabric.

[0033] (5) Shrinking finishing: The dried fabric is processed by a shrinking machine at a temperature of 130°C for 20 seconds to keep the fabric stable and flat.

Embodiment 3

[0035] (1) Stretching: The woven gray fabric is stretched to 12% wider than the required width by the tenter setting machine, which is about 40cm wider than the required width.

[0036] (2) One-time drying: the gray cloth after tentering is dried quickly at a temperature of 160°C, and the drying time is 55 seconds.

[0037] (3) Dyeing and finishing: Dyeing and finishing the dried fabric, and the temperature of the fabric entering the cylinder is controlled at 50°C.

[0038] (4) Secondary drying: Each piece of gray cloth after rapid drying is soaked in water separately and then dehydrated, and dried in a drum dryer at a temperature of 90°C for 20 minutes to make it 70% dry. After finishing the fabric, prevent the fabric from knotting into surface defects, and then dry it again for 8 minutes to straighten the fabric.

[0039] (5) Shrinking finishing: The dried fabric is processed by a shrinking machine at a temperature of 110°C for 30 seconds to keep the fabric stable and flat....

Abstract

The invention discloses a dyeing and finishing process for a loosening structural fabric and relates to the technical field of printing and dyeing of textile. The invention aims to solve the problems of poor processing effect, high cost and complex process caused by a chemical method adopting resins and cross-linking agents for controlling the size stability of the loosening structural fabric. The method comprises the following steps: (1) tentering: widening the width of a piece of weaved gray fabric; (2) once drying: quickly drying the gray fabric after being tentered; (3) dyeing and finishing: dyeing and finishing the fabric after being dried; (4) secondarily drying: dewatering the fabric after being dyed and finished, drying the fabric at seventh dry level and then settling the fabric, and drying again and leveling the fabric; and (5) performing shrinking treatment: treating the dried and leveled fabric by using a shrinking machine and keeping the fabric stable and flat. The dyeing and finishing process provided by the invention is especially suitable for the dyeing and finishing of the loosening structural fabric.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a dyeing and finishing process for loose-structure fabrics. Background technique [0002] Dyeing and finishing is the process of chemically treating textile materials (fibers, yarns and fabrics), which is commonly known as printing and dyeing in modern times. It includes the steps of pretreatment, dyeing, printing and finishing, pretreatment is scouring and bleaching, the purpose is to remove impurities on textile materials; dyeing is to make textile materials have a certain color through the physical or chemical combination of dyes and fibers; Printing is to use color paste to obtain colorful patterns on textiles; finishing is to improve the luster, shape and other appearance of fabrics through physical action or the use of chemicals, improve the wearability of fabrics or make fabrics water-repellent, oil-repellent and other characteristics. [0003] Knitted...
