preparation example 1

[0054] Weigh 141.5g of deionized water and add it to a four-necked flask with stirring, add 1.2g of Pingpinga O, 4.0g of geramine, 1.0g of WA water dispersant and 50g of octamethylcyclotetrasiloxane, and heat it in a water bath Raise the temperature to 40°C and stir for 1 h, add 0.2 g of catalyst KOH, adjust the rotation speed to 300 R, and control the temperature at 70°C for 4 h. Add 0.4g KH602, continue the reaction for 3h to end the reaction; cool to 50°C and add acetic acid to neutralize, adjust the pH to about 7; cool to room temperature and discharge. The lotion is milky with a bluish tinge.

preparation example 2

[0056] Weigh 141.5g of deionized water and add it to a four-neck flask with stirring, add 1.2g of Pingpinga O, 4.0g of germine, 1.0g of WA water dispersant and 60g of octamethylcyclotetrasiloxane, and heat it in a water bath Raise the temperature to 40°C and stir for 1 h, add 0.2 g of catalyst KOH, adjust the rotation speed to 300 R, and control the temperature at 70°C for 4 h. Add 0.5g KH602, continue the reaction for 3h to end the reaction; cool to 50°C and add acetic acid to neutralize, adjust the pH to about 7; cool to room temperature and discharge. The lotion is milky with a bluish tinge.

preparation example 3

[0058] Weigh 141.5g of deionized water and add it to a four-neck flask with stirring, add 1.2g of Pingpinga O, 4.0g of germine, 1.0g of WA water dispersant and 70g of octamethylcyclotetrasiloxane, and heat it in a water bath Raise the temperature to 40°C and stir for 1 h, add 0.2 g of catalyst KOH, adjust the rotation speed to 300 R, and control the temperature at 70°C for 4 h. Add 0.6g KH602, continue the reaction for 3h to end the reaction; cool to 50°C and add acetic acid to neutralize, adjust the pH to about 7; cool to room temperature and discharge. The lotion is milky with a bluish tinge.

Abstract

The invention relates to the technical field of regeneration of waste PET products, and particularly discloses a regenerated polyester staple fiber material and a preparation method thereof. The regenerated polyester staple fiber material comprises 70-80 parts of a regenerated PET material, 10-15 parts of an amino modified organic silicon finishing agent, 5-7 parts of a cross-linking agent and 5-7 parts of a catalyst. The preparation method of the regenerated polyester staple fiber material comprises the following steps of performing screening, proportioning, drying, spinning, circular blowing, oiling, winding, bundling, stretching, crimping, relaxation heat setting and cutting on the waste PET product in sequence to prepare the regenerated polyester staple fiber material. The regenerated polyester staple fiber material can be used for preparing clothes and has the advantage of being not prone to yarn breakage; and in addition, the preparation method provided by the invention has the advantage that the yarn breaking phenomenon is not likely to occur in the production process.

Description

technical field [0001] The application relates to the technical field of regeneration of waste PET products, more specifically, it relates to a recycled polyester staple fiber material and a preparation method thereof. Background technique [0002] Regenerated polyester staple fiber refers to the use of polyester cloth, waste polyester bottle flakes, spinning waste, foam material, pulp block as raw materials, waste bottle flakes are crushed and cleaned, the mixture of various materials is dried, melted and extruded, Spinning, winding, bundling, drafting, crimping (at the same time adding different oils when crimping according to customer needs), relaxing heat setting, and cutting to form polyester staple fibers of different lengths. [0003] Regenerated polyester staple fiber has many advantages such as good strength, heat resistance, elasticity and wear resistance, and the production cost is not high, and the production is convenient and fast. However, broken filaments wil...
