Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of garment fabric, in particular to a suit and trousers fabric and a preparation process thereof. BACKGROUND

[0002] Suit and trousers are the core dress for business and formal occasions, and have the functions of modifying body shape and highlighting temperament, and are important carriers of professional image. With the upgrading of consumption, people's demand for suits has changed from fit and wearability to high quality and stable performance. As the key to affecting the wearing experience and service life, the color stability of the fabric has attracted the attention of consumers.

[0003] At present, the raw material composition of the suit and trousers fabric on the market is mainly wool, polyester fiber, cotton and various blended fibers, and traditional processes such as reactive dyeing and disperse dyeing are often used in the dyeing process.

[0004] However, the fabric generally has a color loss problem in actual wearing and care process, especially during the first washing, daily wearing and after multiple washings. The color loss of the fabric can affect the normal wearing of the suit. During the first washing, a large amount of hesperidin is detached, resulting in deep color of the washing wastewater. If the washing is mixed with other clothes, cross staining can occur, which not only pollutes light-colored clothes, but also increases the difficulty of washing, significantly increasing the cost and time cost of care. During daily wearing, the surface dye of the suit fabric is easily transferred to the skin or underwear due to the effects of sweat infiltration and friction, especially for dark fabric, which can seriously affect the appearance and cause discomfort to sensitive people due to contact with the skin. Of course, if the originally uniform and full color of the suit fabric fades or becomes dull after multiple washings, the visual quality of the overall style of the suit and trousers will be greatly reduced, which cannot meet the requirements of business occasions for the neatness and delicacy of the clothes, and significantly shortens the service life, which needs to be improved.

The thiol binds the ion bridging agent to fix the polyester targeted molecularly imprinted polymer on the fiber surface of the base fiber fabric to improve the firmness of the dye and the fiber of the base fiber fabric. At the same time, the dispersed dye is modified by a disulfide bond to specifically recognize the polyester targeted molecularly imprinted polymer, thereby guiding the dye to directionally aggregate to achieve the purpose of preventing color bleeding, and the cross-linked network loads the dye, cooperates with the disulfide bond and the Schiff base dye dynamic bonding to reduce the loss, so that the polyester targeted molecularly imprinted polymer has the effect of filling the fiber gap to form support and improving the wrinkle resistance and dimensional stability of the suit and trousers fabric. And the Schiff base type reactive dye realizes recombination repair of local discoloration under the action of a light response catalyst, and the Schiff base structure forms a strong binding force with the fiber group of the targeted recognition fabric to achieve the purpose of improving color fastness.
