Abstract

The invention discloses a production method for high-color-fastness polyester-cotton drawing yarn. The polyester-cotton blended yarn is obtained after blending positive-ion modified polyester fibers and combed cotton; the production method includes the following specific steps of A, opening picking; B, cotton carding; C, pre-dyeing; D, drawing; E, roving; F, dyeing; G, spinning. The polyester-cotton blended yarn has the advantages of being even in evenness, small in the number of hairiness, soft in hand feeling and the like; in the technology, short fiber card slivers are pre-dyed, and are subjected to drawing, then roving is conducted, dyeing is conducted, and the color fastness of the yarn is improved through secondary dyeing, and can reach level 3 to level 4.

Description

technical field [0001] The invention relates to the technical field of textile product production methods, in particular to a production method of polyester-cotton drawn yarn with high color fastness. Background technique [0002] Polyester-cotton refers to the general term for blended fabrics of polyester and cotton, which began to appear in China in the early 1960s. The fabric is very popular among consumers because of its crispness, smoothness, quick drying, and durability. , is commonly known as "really cool". At present, blended fabrics have developed from the original ratio of 65% polyester to 35% cotton to blended fabrics with different ratios of 65:35, 55:45, 50:50, 20:80, etc. The purpose is to adapt to different levels. consumer needs. [0003] The disadvantages of the above-mentioned polyester-cotton fabrics are: due to the characteristics of ordinary polyester fibers, the dyeing rate is low and the color fastness is low, and the "high temperature and high press...
