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 the crosslinking of the finishing working solution too fast, which makes the surface of the fabric fiber transitionally crosslinked, and the internal crosslinking reaction of the fiber is insufficient. Fully, the fiber is damaged greatly, which leads to the decrease of fabric strength and affects the fabric treatment effect
[0004] In addition, lower the curing temperature, too mild curing conditions will make the inside of the fiber unable to complete cross-linking due to low temperature, and the effect of anti-shrinkage and anti-wrinkle treatment is poor
[0005] Furthermore, shortening the baking time will make it impossible to complete the full cross-linking in the fiber in time, which will still lead to the problem of poor fabric treatment effect.
[0006] The existing linen fabric after baking and setting usually adopts open-width continuous washing process. Since the fabric travels flat with the open-width washing machine, the fabric is not subjected to mechanical friction, and the fabric treated by this washing process has the disadvantage of hard hand feeling. , while open-width continuous washing uses flowing water sources, so water resources are seriously wasted

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:
