Abstract

The invention relates to preparation of a master batch for a low-melting-point polyester colored fiber. The low-melting-point polyester master batch provided by the invention comprises the following components in parts by weight: 60-88 parts of low-melting-point polyester, 5-20 parts of polyamide wax, 5-30 parts of pigment and 0.1-0.3 part of stabilizer, wherein the melting point of the low-melting-point polyester is 100-160 DEG C; the polyamide wax is solid micropowder of which the particle size is no more than 5 micrometers; the pigment is carbon black, azo pigment, anthraquinone pigment or polycyclic pigment; and the stabilizer is a compound comprising 50wt% of IRGAFOS168 and 50wt% of IRGANOX1010. The invention is applicable to preparation of a low-melting-point polyester colored fiber.

Description

technical field [0001] The invention relates to a color masterbatch for spinning, in particular to a preparation of a color masterbatch suitable for low-melting-point polyester colored fibers, and a method for processing low-melting-point composite colored fibers from the masterbatch. Background technique [0002] Low-melting point polyester sheath-core composite fiber is a kind of hot-melt fiber. Generally, its core component is ordinary fiber-grade polyester polyester, and the sheath is low-melting point polyester with a melting point of 100-160°C. For example, the authorized announcement date is 2010.05.12, The authorized notification number is the invention patent of CN 1962716 B, which discloses a synthesis method of low melting point polyester. Low-melting point polyester sheath-core composite fibers are mainly used in non-woven fabrics such as carpets, decorations, non-glued cotton, etc., and have good physical processing properties and environmental protection effect...
