Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. The material proportions in the present invention are all described in mass fractions, and the sum of the mass fractions of all material components of the anti-wrinkle finishing agent is 100%.

[0019] The anti-wrinkle finishing agent provided by the invention includes cellulose crosslinking agent, dispersant, acetic acid, titanium dioxide and water. The mass fraction of each raw material is as follows:

[0020]

[0021] Preferably, the cellulose crosslinking agent can be any cellulose crosslinking agent well known and applicable to those skilled in the art, such as dimethylol dihydroxyethylene urea (DMDHEU), melamine formaldehyde resin or dimethylolethylene Urea (DMEU). As the dispersant, any dispersant that is well known and applicable to those skilled in the art can b...

Abstract

The invention relates to a crease resistance finishing agent, a fabric crease resistance finishing method, and a crease-resistant fabric. The crease resistance finishing agent comprises the following raw materials by mass: 4 to 6% of a cellulose cross-linking agent, 0.04 to 0.06% of magnesium chloride, 9 to 11% of a dispersing agent, 0.05 to 0.15% of acetic acid and 0.05 to 0.15% of titanium dioxide, with the balance being water. The fabric crease resistance finishing method employs the crease resistance finishing agent for pad dyeing, drying and curing of a fabric, wherein in a curing step, curing temperature is 140 to 160 DEG C and curing time is 1 to 2 min. According to the invention, due to addition of titanium dioxide as a cocatalyst, curing temperature in the process of crease resistance finishing is lowered, curing time is shortened, the finished fabric can maintain good crease resistance under the condition of reduction in crease resistance finishing cost, and the content of free formaldehyde in the finished fabric is decreased.

Description

technical field [0001] The invention relates to fabric anti-wrinkle finishing technology, more specifically, relates to an anti-wrinkle finishing agent, a fabric anti-wrinkle finishing method and an anti-wrinkle fabric. Background technique [0002] Cotton is an important textile fiber with good strength, abrasion resistance, high moisture absorption and fast drying properties, and they rarely have problems with static electricity or pilling. However, one of the main disadvantages of cotton is that it wrinkles after washing, but this disadvantage has now been solved by anti-wrinkle agents. Cotton's polymer chains are linked by many hydroxyl groups, and include three regions with different degrees of order, namely, crystalline regions, amorphous regions, and intermediate regions between the two. In the crystalline region, the cotton's polymer chains are tightly packed together, which limits their mobility and the detectability of the molecules. On the other hand, the chains...
