Problems solved by technology
[0003] The light and thin all-wool rib knitted fabric in the related art is woven by a circular machine, and its preparation method includes: blank weaving → kiln matching → dyeing → dehydration → drying → opening → shaping → woolen blanket. Wool rib knitted fabric has excellent comfort and warmth retention performance, but its structure is relatively loose, and it cannot be shaped well like chemical fibers. Used as clothing body fabric
[0004] Fabrics for the body of clothing are required to keep the size of the finished garments basically stable after repeated washings, without serious skew and deformation. Obviously, the existing all-wool rib knit fabrics cannot meet this requirement, so it is urgent to develop a Dimensional stabilizer for all-wool rib knit fabrics, resulting in all-wool rib knit fabrics with high dimensional stability

Embodiment 1
[0039] A size stabilizer, the components and their corresponding parts by weight are shown in Table 1, and are prepared through the following steps: a. After mixing aldehydes and phenol, first adjust the pH to 3, and react at 100°C 2 hours, made premix, wherein aldehydes are malondialdehyde;
[0040] b. Adjust the premixed material to 7, lower the temperature to 60°C, then add the metal complex, which is chloroplatinic acid, and react for 1 hour to prepare the size stabilizer.
Embodiment 2-6
[0042] A dimension stabilizer, the difference from Example 1 is that each component and its corresponding weight are as shown in Table 1.
[0043] Each component and its weight (kg) in table 1 embodiment 1-6
[0044]
Embodiment 7
[0046] A kind of dimension stabilizer, the difference with embodiment 1 is that its preparation process is as follows:
[0047] a. After mixing aldehydes and phenol, first adjust the pH to 4, and react at 90°C for 1.5 hours to obtain a premix;
[0048] b. Adjust the premix to 8, lower the temperature to 50°C, then add the metal complex and react for 0.75h to prepare the size stabilizer.

Abstract
The invention relates to the technical field of textile, in particular to a size stabilizer and a preparation method and application thereof. The size stabilizer is prepared from the following components in parts by weight: 20 to 100 parts of phenol, 200 to 300 parts of aldehydes and 100 to 150 parts of metal complex. Through compounding of phenol, aldehydes and metal complexes, the size stabilizer is endowed with excellent performance, and when the size stabilizer is applied to the wool rib fabric, the size stabilizer can improve the loose structure of wool fibers and can also reduce the moisture absorption of the wool fibers, so that the effect of stabilizing the size of the wool rib fabric is achieved.
Description
technical field [0001] The application relates to the field of textile technology, more specifically, it relates to a dimension stabilizer and its preparation method and application. Background technique [0002] Wool fabric is a fabric made of wool as raw material. It has excellent texture, warmth retention and hygroscopicity, so it is loved by people and is widely used in the production and processing of high-end clothing fabrics. Among them, the most commonly used light and thin An all-wool ribbed knit fabric, for example. [0003] The light and thin all-wool rib knitted fabric in the related art is woven by a circular machine, and its preparation method includes: blank weaving → kiln matching → dyeing → dehydration → drying → opening → shaping → woolen blanket. Wool rib knitted fabric has excellent comfort and warmth retention performance, but its structure is relatively loose, and it cannot be shaped well like chemical fibers. It is used as fabric for clothing body. ...
