Embodiment 1

[0016] Example 1: Polytrimethylene terephthalate (PTT) was used as a raw material to produce 140D / 72f pre-oriented yarn (a) with a monofilament fineness of 1.9dpf, a hexalobal cross-section, and an elongation at break of about 85%; Use polyester FDY drawing equipment to produce 100D / 36f, single filament fineness is 2.8dpf, fully drawn high boiling water shrinkage yarn (b), modified with isophthalic acid and isoprene glycol, boiling water shrinkage rate is 40%, cross section Circles and hexagons. Composite is carried out on the Murata false twist texturing machine model 33H, the pre-oriented yarn (a) passes through one roller, one hot box, cooling plate, false twister in turn, and shrinks before the second roller and passes through the zero roller full-drawing high boiling water The filaments (b) are merged, then compounded by the network device, and then sequentially passed through the second heat box, the third roller, the oil tanker, and finally wound into filaments. The pr...

[0017] Example 2: Polytrimethylene terephthalate (PTT) was used as a raw material to produce 100D / 72f pre-oriented yarn (a) with a monofilament fineness of 1.4dpf, a hexalobal cross-section, and an elongation at break of about 85%; Use polyester FDY drawing equipment to produce 100D / 36f, single filament fineness is 2.8dpf, fully drawn high boiling water shrinkage yarn (b), modified with isophthalic acid and isoprene glycol, boiling water shrinkage rate is 30%, cross section Circles and quadrilaterals. Composite is carried out on the Murata false twist texturing machine model 33H, the pre-oriented yarn (a) passes through one roller, one hot box, cooling plate, false twister in turn, and shrinks before the second roller and passes through the zero roller full-drawing high boiling water The filaments (b) are merged, then compounded by the network device, and then sequentially passed through the second heat box, the third roller, the oil tanker, and finally wound into filaments. ...

Embodiment 3

[0018] Example 3: Polytrimethylene terephthalate (PTT) was used as a raw material to produce 140D / 72f pre-oriented yarn (a) with a monofilament fineness of 1.9dpf, a quatrefoil-shaped cross section, and an elongation at break of about 85%; Using polyester FDY drawing equipment to produce 75D / 24f, single-filament fineness of 3.1dpf, full-drawing high-boiling water shrinkage yarn (b), modified with isophthalic acid and isoprene glycol, boiling water shrinkage rate of 45%, cross-section circles and triangles. Composite is carried out on the Murata false twist texturing machine model 33H, the pre-oriented yarn (a) passes through the shredder, the first roller, the first heat box, the cooling plate, the false twister in sequence, before the second roller and the full drawing of the zero roller Stretching and boiling water shrinkage yarns (b) converge, and then compounded by the network device, and then passed through the second heat box, the third roller, the oil tanker, and finall...

Abstract

The invention discloses a preparation method of novel wool-like differential fibers, which is characterized by comprising the following steps of: 1) adopting polytrimethylene terephthalate (PTT) as a raw material to prepare a pre-oriented yarn (a); 2) adopting modified high-shrinkage polyester as a raw material to prepare fully-drawn high boiling water shrinkage fibers (b); and 3) on a DTY machine, passing the pre-oriented yarn (a) through a roller, a hot box and a cooling plate, performing drawing false twisting on the pre-oriented yarn on a false twister, converging the pre-oriented yarn with the high boiling water shrinkage fibers (b) in front of two rollers, and performing network compounding on the pre-oriented yarn and the high boiling water shrinkage fibers, and then passing the pre-oriented yarn and the high boiling water shrinkage fibers through two hot boxes to obtain a composite yarn product. The preparation method develops the novel wool-like differential fibers, the PTT fibers floating on the surface layer are much closer to wool fibers in performance and are superior to common wool-like products in the performance of elastic recovery, handfeel, antistatic property, dyeing and the like, and simultaneously, the treatment of forming different sections of the two raw materials ensures that the products have significant improvements on luster and fibrillation resistance.

Description

technical field [0001] The invention relates to the technical field of producing polyester composite filaments, in particular to a method for preparing novel wool-like differentiated fibers. Background technique [0002] At present, there are endless polyester wool-like products on the market, but they are generally based on the composite processing of some conventional raw materials. With the continuous emergence of new raw materials, the development field of multiple and changeable composite fibers is wider. Differential fibers refer to chemical fibers that are innovative or have a certain characteristic of conventional chemical fibers, and are mainly produced through chemical modification or physical deformation of chemical fibers. Polytrimethylene terephthalate (PTT) fiber is a new type of fiber that has emerged in China in recent years. The fiber has excellent wearability, soft hand feeling, excellent elasticity, and hygroscopicity, antistatic performance, and stain res...
