Problems solved by technology

The disadvantage of this method is that the process flow is long and the process flexibility is poor.
[0006] 3) More advanced anti-felting treatment: plasma, enzyme pretreatment, polymer treatment, some methods are more costly
The disadvantage is that the production process is longer
The dyed product is prone to discoloration and has poor styling durability
[0008] Regardless of the method, there is no relatively perfect finishing process with long-lasting and stable shape, especially the one-step finishing process for anti-felting and long-lasting and stable shape of garments made of ordinary worsted fabrics

Effect test

example 1

[0064] Example 1, the preparation of water-soluble polyurethane WFI-1:

[0065] Organic polyol:isocyanate=1:1-3 (molar ratio), the two are mixed in a solvent at a certain ratio, and stirred and reacted at a temperature of 20-80° C. for 10-60 minutes. After the reaction is completed, a blocking agent is added to block unreacted isocyanate groups.

example 2

[0066] The preparation of example 2, setting agent WS-1:

[0067] Adjust the pH value of sulfurous acid organic amine salt with 1:1 sulfuric acid to make pH = 4-7, then add a specified amount of sodium bisulfite, urea, and alkyl polyoxyethylene ether phosphate under stirring at room temperature, and wait until fully After the reaction, a colorless or light yellow transparent liquid is obtained, which is WS-1.

[0068] Proportion: sulfite organic amine salt (27%) 50-80%

[0069] 1:1 sulfuric acid (for pH adjustment) appropriate amount

[0070] Urea 2-8%

[0071] Alkyl polyoxyethylene ether phosphate 2-8%

[0072] Add water to 100%

example 3

[0074] Step by step arrangement embodiment (trousers):

[0075] (1) Fabric specifications: Varitin (60N / 2×40N / 1, 220×208) has a weight of 220g / m, and the length of the fabric is about 100m:

[0076] (2) Finishing solution (150kg in total):

[0077] WF1-1 15-60kg

[0078] Catalyst C 0.5-9kg

[0079] JFC 1.5-4.5g

[0080] Add water to 150kg

[0081] (3) Finishing process:

[0082] Padding working solution (liquid loading rate 50-100%)→pre-baking (60-100°C, 2-4 minutes)→baking (120-180°C, 1-3 minutes):

[0083] (4) Trousers made of the above fabrics:

[0084] (5) Take a pair of trousers as an example (about 400g) with finishing liquid (150g);

[0085] WS-1 25-100g

[0086] Catalyst C 1-10g

[0087] Penetrant JFC 0.005-0.015g

[0088] Add water to 150g

[0089] (6) Spray the finishing liquid prepared in step 5 evenly on the trousers, spray more on the creases and wrinkles, and then press and shape it with a steam iron or a press at 100-170°C.

Abstract

A finishing process for making the shape of worsted goods and clothes durable and stable is characterized by antifelting agent WFI-1 and a shape fixating agent WS-1, which are prepared from the water-soluble polyurethane, are provided for them.

Description

Technical field: [0001] The invention belongs to the technical field of textiles. Specifically, it relates to a finishing process for worsted wool fabrics and garments with a durable and stable shape. Background technique: [0002] Due to the phosphor sheet structure on the surface of the wool fiber, during the washing process, reverse movement occurs and intertwines each other, resulting in felting. In addition, because the chemical composition of wool fiber is protein, during washing, the disulfide bonds, hydrogen bonds and other bonds between molecules are dismantled under the action of water, and new bonds are re-formed in new positions, so after washing The original form of the wool fabric cannot be preserved. Therefore, people are committed to research on how to prevent wool from shrinking and washing without deformation. It is generally believed that there are two ways to prevent felting. One is to destroy the scale layer on the surface of wool fiber and reduce its...
