Problems solved by technology

[0002] Linen fabric has the characteristics of high strength, good moisture absorption, antibacterial and antibacterial, so it has the advantages of easy sweat absorption, breathability, antibacterial hygiene, and good anti-ultraviolet performance. However, due to the strong rigidity of linen fabric, small fracture extension, poor elasticity and softness Small, so it feels rough, dry and easy to wrinkle. For a long time, in the anti-shrinkage and anti-wrinkle finishing process, there have been technical problems that have restricted the popularization and application of linen fabrics. Therefore, on the basis of maintaining the unique style of linen fabrics, how to solve the contradiction between wrinkle resistance and strength through anti-shrinkage, anti-wrinkle and soft treatments on the fabrics, and how to improve the handle of linen fabrics has become an important issue in the dyeing and finishing industry. Realistic and urgent research topics
[0003] The existing anti-wrinkle and anti-wrinkle finishing technology usually directly bakes the linen fabric after padding and finishing the working solution at high temperature. The sharp high temperature promotes th

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 anti-shrinkage and anti-wrinkle post-treatment process of linen fabric includes the linen fabric after padding and finishing working solution, and the process steps are low-temperature drying, high-temperature baking, drum machine washing, drum drying and pre-shrinking process. Specifically:

[0015] 1. Low temperature drying

[0016] It is carried out on a high-temperature setting machine. According to the weight and strength of the cloth, the oven temperature is 80°C, and the time is 100 seconds, so that the surface of the fabric and the inside of the fiber can be cured gently at the same time, and the amount of finishing adsorbed is uniform, avoiding over-crosslinking of the finishing working solution. Fast happens.

[0017] 2. High temperature baking

[0018] It is carried out in a baking machine. According to the weight a...

Embodiment 2

[0027] Example 2: Now the yarn count is 12×12, the specification is 48×48, and the gram weight is 225g / m 2 Linen fabrics as an example.

[0028] Process step and condition are with embodiment 1.

[0029] According to the cloth weight and strength, the difference is: the pre-drying temperature is set to 90°C, the pre-drying time is set to 90 seconds, the baking temperature is set to 150°C, the baking time is set to 90 seconds, and the tumbler is machine washed and dried. The tumble drying time was 45 minutes.

[0030] 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:

[0031]

Embodiment 3

[0032] Embodiment 3: Now use yarn count 9×9, specification 42×42, gram weight 260g / m 2 Linen fabrics as an example.

[0033] Process step and condition are with embodiment 1.

[0034] According to the cloth weight and strength, the difference is: the pre-drying temperature is set to 100°C, the pre-drying time is set to 80 seconds, the baking temperature is set to 155°C, the baking time is set to 80 seconds, and the tumbler is machine washed and dried. The drum drying time was 60 minutes.

[0035] 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:

[0036]

[0037] The data in the above three tables show that:

[0038] The linen fabric treated by the invention is superior to the products in the prior art, and has good anti-shrinkage and anti-wrinkle performance, good fabric strength, and the reliability and stability of quality reach an advanced level.

Abstract

The invention discloses a shrinkproof crease-resistant pretreatment technique of flax fabric, which comprises the flax fabric accomplished by adopting padding finishing working liquid. The technical steps thereof comprise the working procedures of: high-temperature baking, softening treatment and preshrinking; while a low-temperature pre-drying process is added before the high-temperature baking; the pre-baking temperature of the low-temperature pre-drying process is controlled between 80 and 100 DEG C; the pre-baking time is between 80 and 100 seconds; the baking temperature of the high-temperature pre-drying process is controlled between 145 and 155 DEG C and the baking time is between 80 and 100 seconds; the softening treatment comprises revolving drum machine washing and revolving drum drying; the working conditions of the revolving drum machine washing are as follows: the temperature is of 35 DEG C and the time is between 30 and 60 minutes; the working conditions of the revolving drum drying are as follows: the temperature is of 50 DEG C and the time is between 30 and 60 minutes. The flax fabric formed by the technique completely solves the conflict between the crease-resistant performance thereof and the strength of the fabric, and has excellent shrinkproof and crease-resistant performances as well as small strength loss; moreover, the flexibility of the hand feeling of the fabric is excellent. The technique ensures the reliability and stability of the product quality and has extremely high popularization and application values in the dyeing and finishing industry.
