Embodiment 1

[0039] A kind of preparation method of woolen fabric, its process is as follows:

[0040] (1) prepare the monofilament of different shrinkage linen-like polyester fiber:

[0041] (1.1) After PET (intrinsic viscosity is 0.63dL / g) is spun according to the POY process and the FDY process, it is plied and paralleled; the mass ratio of the POY silk produced by the POY process to the FDY silk produced by the FDY process is 50 :50;

[0042] The spinneret hole on the spinneret corresponding to the POY process is a conventional trilobal shape; the three lobes of all conventional trilobal spinneret holes have the same length and the same width, and the ratio of length to width is 2.8:1, and the adjacent two lobes The included angle between the centerlines of is 120°;

[0043] The parameters of the POY process are: the cooling wind speed is 0.5m / s;

[0044] The spinneret hole on the spinneret corresponding to the FDY process is a T-shaped three-lobed spinneret; the three leaves of all...

Abstract

The invention relates to a method for preparing a woollen fabric, which comprises iso-shrinkage hemp-like polyester fibers with a monofilament fineness of 3.5-3.7 dtex. Type trilobal spinneret) after spinning, plied and filamented, and then through network compounding, winding forming and relaxation heat treatment to obtain iso-shrinkage hemp-like polyester fiber; wool fiber yarn and iso-shrink hemp-like polyester fiber yarn are After being blended into wool and polyester yarn with a mass ratio of 70:30, the woollen fabric is made by the processes of meridian winding, warping, drawing reed, weaving, etc. The porosity of the fabric is 75-81%, and the air permeability is 263-368mL / cm 2 ·s, the moisture permeability is 430~491g / m 2 24h, thermal resistance is 1.43×10 ‑3 ~1.68×10 ‑3 K m 2 / W, the stiffness is 4.1-5.2, and the fullness is 5.6-7.0.

Description

technical field [0001] The invention belongs to the technical field of textile fabrics, and relates to a method for preparing woolen fabrics. Background technique [0002] Slub wool fabric has the characteristics of thick texture, plump and strong hand feeling, not easy to deform and good warmth retention. When weaving woolen wool fabric, roving is generally selected as raw material, but it will lead to thick fabric, unsatisfactory air permeability and moisture permeability, and poor hand feeling. etc., and the current consumers are pursuing lightweight clothing, the deficiency of only using roving as raw material is becoming more and more obvious. [0003] Based on the above problems, in the prior art, the method of worsted surface and woolen bottom is adopted, and the part of the woolen bottom can make the fabric crisp and thick; the part of the worsted surface can be soft, fluffy, breathable, etc., presenting a new style This kind of fabric needs to form two sides, the s...
