preparation example Construction

[0046] The preparation technology of wax dispersion liquid among the present invention is as follows:

[0047] Add water, acid-base regulator, wax and emulsifier in a specified weight ratio into a closed reactor, and heat the mixture to melt it completely.

[0048] Under the temperature condition of 10-30 DEG C higher than the wax melting point, it is preferred to keep stirring for 20-30 minutes.

[0049] After the heat preservation is over, it is rapidly cooled to room temperature to obtain the required wax dispersion.

[0050] The preparation process of the smooth softening agent composition for yarn of the present invention is as follows:

[0051] Add the selected aliphatic derivative softener into a specified amount of warm water, stir for a period of time, cool to room temperature, and prepare a uniform aliphatic derivative softener dispersion.

[0052] Then, the prepared aliphatic derivative softener dispersion and the above-prepared wax dispersion are mixed and stirre...

Embodiment 1

[0068] Embodiment 1: the preparation of smooth softening agent composition A

[0069] Add 346 grams of water, 4 grams of acetic acid, 22 grams of cetyl alcohol, 16 grams of Pinpinga O-5, 22 grams of 1815 and 90 grams of Luxaw OA in a closed reactor, and heat the mixture to melt it completely. Insulate and stir at 125°C for 20-30 minutes. After the heat preservation was completed, it was rapidly cooled to room temperature to obtain a wax dispersion A.

[0070] Add 1300 grams of hot water (70°C) to another reactor, and add 200 grams of softener FS into the reactor, stir for 10-15 minutes, and cool to room temperature; then add the wax dispersion prepared above A. Stir for 15-20 minutes to prepare smooth softener A.

Embodiment 2

[0071] Embodiment 2: the preparation of smooth softening agent composition B

[0072] 240 kg of water, 5 kg of acetic acid, 21 kg of 1810, 56 kg of carnauba wax and 28 kg of Luxaw OA were added to a closed reactor, and the mixture was heated to completely melt. Insulate and stir at 125°C for 20-30 minutes. After the heat preservation is completed, it is rapidly cooled to room temperature to obtain a wax dispersion B.

[0073] Add 135 kg of hot water (70°C) into another reactor, and add 15 kg of softener FS into the reactor, stir for 10-15 minutes, and cool to room temperature; then add the wax dispersion prepared above B. Stir for 15-20 minutes to prepare smooth softener B.

Abstract

The invention discloses a smoothening softener composition for smoothening and softening finishing of cotton and its blended yarns, a preparation method thereof and an application thereof. The smoothening softener composition comprises 2-30wt% of wax, 1-20wt% of an emulsifier, 0-3wt% of a pH value adjusting agent, 0-15wt% of an aliphatic derivative softener and 55-90wt% of water, wherein the total weight of the smoothening softener composition is treated as a reference. By adopting the smoothening softener to carry out the smoothening and softening finishing, the yarns have good feels, the strengths of the yarns are effectively protected, and the finished yarns have excellent weaving performances.

Description

technical field [0001] The invention relates to a smoothing and softening agent composition for cotton and its blended yarn, its preparation method and application. Specifically, the present invention relates to a smoothing and softening agent composition for smoothing and softening finishing of cotton and its blended yarns after pretreatment and dyeing processing, as well as its preparation method and application. Background technique [0002] In the process of textile printing and dyeing, after the fabric or yarn is pre-treated and dyed, due to the action of various chemicals and strong machinery, the hand feeling of the fabric or yarn will become rough. For a smooth and soft finish. [0003] Smooth and soft finishing can not only improve the handle of fabric or yarn, but also further improve and improve the post-processing performance of fabric or yarn. [0004] For yarn, after the printing and dyeing process is completed, it needs to be weaved on the machine to become ...
