Problems solved by technology

[0002] The known anti-shrinkage and anti-wrinkle dyeing and finishing process of linen fabrics after dyeing is to adopt the method of dipping and padding on the setting machine. This traditional process has the disadvantage of low production efficiency when processing fabrics. The time for rolling and finishing the working solution is too short, resulting in insufficient liquid absorption inside the fabric fiber, and the finishing effect of anti-shrinkage and anti-wrinkle strength loss is not achieved.

Embodiment 1

[0013] Example 1: Now the yarn count is 14×14, the specification is 54×54, and the gram weight is 170g / m 2 Linen fabrics as an example.

[0014] The dyeing and finishing process of linen fabrics with anti-shrinkage, anti-wrinkle and low strength loss includes the steps of second-dipping and second-rolling finishing working liquid of linen fabrics after dyeing, high-temperature baking, washing, drying and pre-shrinking, specifically:

[0015] 1. Padding finishing working solution

[0016] In order to ensure the full penetration of the finishing working solution, the fabric adopts the second padding and finishing working solution step on the setting machine. According to the weight and strength of the cloth, the excess rate of the first padding and finishing working solution is 95%, and the pressure of the first pressing roller is 95%. 1.5Kg, the speed of the shaping machine is 55 m / min.

[0017] The resin cross-linking agent is preferably F-ECO resin cross-linking agent produ...

Embodiment 2

[0031] Example 2: Yarn count 12×12, specification 48×48, gram weight 225g / m 2 linen fabric.

[0032] Process step is the same as embodiment 1, according to cloth weight and strong force, difference is that the pressure of the first roller is 1.6Kg, the pressure of the second roller is 1.9Kg, and the speed of the shaping machine is 50 meters per minute.

[0033] According to the cloth weight and strength, the formula of the finishing working liquid used in the second padding step is: BASF F-ECO resin crosslinking agent is 80g / L, Tuona USV water-soluble polyurethane strong protective agent is 35g / L , BASF F-M catalyst is 20g / L, Taifeng T80A modified silicone softener is 40g / L, and the rest is water.

[0034] 12×12, 48×48, gram weight 225g / m produced according to the above process 2 The linen products, after 3 times of washing, the test data are as follows:

[0035]

Embodiment 3

[0036] Embodiment 3: Yarn count 9×9, specification 42×42, gram weight 260g / m 2 linen fabric.

[0037] Process step is the same as embodiment 1, according to cloth weight and strong force, difference is that the pressure of the first press roller is 1.7Kg, the pressure of the second press roller is 2.0Kg, and the speed of the sizing machine is 40 meters per minute.

[0038] According to the cloth weight and strength, the formula of the finishing working liquid used in the second padding step is: BASF F-ECO resin crosslinking agent is 100g / L, Tuona USV water-soluble polyurethane strong protective agent is 40g / L , BASF F-M catalyst is 25g / L, Taifeng T80A modified silicone softener is 50g / L, and the rest is water.

[0039] 9×9, 42×42 produced according to the above process, and the weight is 260g / m 2 The linen products, after 3 times of washing, the test data are as follows:

[0040]

[0041] The data in the above three tables show that:

Abstract

The invention discloses a shrinkproof crease-resistant low strength loss flax fabric dyeing and finishing technique, which belongs to the technical field of dyeing and finishing. The technical flow comprises the working procedures of: padding the flax fabric after being colored through finishing working liquid, baking at high temperature, rinsing, drying and pre-shrinking. The working procedure of padding through the finishing working liquid comprises the finishing working procedures of two dipping and two rolling; the padding pick-up of the first finishing working liquid is 90-100 percent, the pressure is 1.5-1.7Kg and the vehicle speed is 40-55 meters / minute; the padding pick-up of the second finishing working liquid is 60-70 percent, the pressure is 1.8-2.0Kg and the vehicle speed is 40-55 meters / minute; the prescription of the second padding finishing working liquid comprises 60-100g / L of resin cross linking agent, 15-25g / L of catalyst as well as 30-50g / L of softening agent. The flax fabric processed by the technique solves the contradiction between the processing yield and quality of fabric. The shrinkproof crease-resistant performance of the processed fabric is excellent, the strength loss is small and the processing yield is high. The shrinkproof crease-resistant low strength loss flax fabric dyeing and finishing technique has extremely high popularization and application values in the dyeing and finishing industry.

Description

technical field [0001] The invention relates to an anti-shrinkage, anti-wrinkle and low-strength loss flax fabric dyeing and finishing process, which belongs to the technical field of dyeing and finishing. Background technique [0002] The known anti-shrinkage and anti-wrinkle dyeing and finishing process of linen fabrics after dyeing is to adopt the method of dipping and padding on the setting machine. This traditional process has the disadvantage of low production efficiency when processing fabrics. The time for rolling the finishing working solution is too short, resulting in insufficient liquid absorption inside the fabric fibers, and the finishing effect of small loss of anti-shrinkage and anti-wrinkle strength cannot be achieved. [0003] Therefore, how to solve the contradiction between the production efficiency of fabric treatment and the quality of fabric treatment in the padding finishing process, so as to achieve the purpose of ensuring the quality of fabric treat...
