Embodiment 1

[0016] The present invention also discloses a preparation method of the above-mentioned polyester modified Haifu top, the steps of which include:

[0017] 1) Polyester modification: adding 2% mole of dimethyl isophthalate-5-sodium sulfonate (SIPM) and 0.5% polyester weight polyethylene glycol with a molecular weight of 4000 during PET polymerization;

[0018] 2) Add 6%wt of environmentally friendly colored masterbatch in the modified polyester chips, the environmentally friendly colored masterbatch is made of color-fixing polyester as a carrier and 15%wt of carbon black, wherein the color-fixing polymer The ester is formed by the copolymerization of purified terephthalic acid and ethylene glycol as the basic raw materials, and also contains polyethylene glycol accounting for 0.5-0.8% of the weight of the color-fixing polyester and having an average molecular weight of 4000-8000. Its structure is listed in CN103113564A It has been disclosed in the paper that after fully mixing,...

Abstract

The invention discloses polyester-modified Haifu top, characterized by comprising 94% of cation-modified polyester and 6% of environment-friendly colored masterbatch; the environment-friendly coloredmasterbatch is made by adding 15% of carbon black to color-fixing polyester as a carrier. A preparation method of the polyester-modified Haifu top is also disclosed. After the environment-friendly colored masterbatch and the modified polyester are mixed, direct melt spinning is performed; polyester modification helps provide good spinnability and improve fiber color fastness and moisture-holding capacity. The prepared fiber has good spinning performance; the polyester-modified Haifu top has good anti-pilling performance; the environment-friendly colored masterbatch used herein has good dispersibility such that the prepared fiber has uniform color, good color fastness, bright color and zero aberration. A spun dyeing technique used herein such that dyeing cost is lowered, and mass wastewater caused during bath dyeing in downstream enterprises is avoided.

Description

technical field [0001] The invention relates to a polyester modified Haifu top and a preparation method thereof. Background technique [0002] In recent years, with the advancement of science and economic development, the functional textile industry has rapidly developed into an important pillar of textile products. According to different product characteristics and different processes, the types of functional textiles are increasing. Obtain anti-pilling, antistatic, hydrophilic, high shrinkage, flame retardant and other properties; through fiber molding modification, the product can obtain hollow, special-shaped, ultra-fine, composite and other functions, making textile products light, comfortable and safe Environmental protection and other requirements. [0003] With the continuous improvement of living standards, woolen fabrics require not only warmth, but also aesthetics and grades. Anti-pilling performance is an important indicator to measure the intrinsic quality of w...
