Embodiment 1

[0025] A new type of polyester-cotton blended yarn, including cationic upgraded modified polyester fiber and combed cotton. The polyester-cotton blended yarn is uniformly mixed with 65% polyester fiber and 35% combed cotton.

[0026] The above-mentioned new polyester-cotton blended yarn is blended with cationic modified polyester fiber and combed cotton. The monofilament fineness of cationic modified polyester fiber is 1.56-1.59dtex, and the length is 37.6-38.0mm; the micronaire value of combed cotton is 3.7~4.2, the length is 29.2~30.9mm, the specific steps are as follows:

[0027] The first step, polyester fiber treatment: the treatment process is followed by cleaning, carding and pre-merging. Among them, the cleaning process adopts the principle of short process and light blow to reduce the damage and rubbing of polyester fibers; the carding process, according to the polyester fiber In order to ensure the carding and smooth transfer of polyester fibers, take measures to lig...

Embodiment 2

[0032] A new type of polyester-cotton blended yarn, consisting of cationic upgraded modified polyester fiber and combed cotton, which is evenly mixed with 65% polyester fiber and 35% combed cotton.

[0033] The above-mentioned new polyester-cotton blended yarn is blended with cationic modified polyester fiber and combed cotton. The monofilament fineness of cationic modified polyester fiber is 1.56-1.59dtex, and the length is 37.6-38.0mm; the micronaire value of combed cotton is 3.7~4.2, the length is 29.2~30.9mm, the specific steps are as follows:

[0034] The first step, polyester fiber treatment: the treatment process is followed by cleaning, carding and pre-merging. Among them, the cleaning process adopts the principle of short process and light blow to reduce the damage and rubbing of polyester fibers; the carding process, according to the polyester fiber In order to ensure the carding and smooth transfer of polyester fibers, the sliver weight is set at 22g / m, and the doff...

Embodiment 3

[0039] A new type of polyester-cotton blended yarn, consisting of cationic upgraded modified polyester fiber and combed cotton, which is evenly mixed with 65% polyester fiber and 35% combed cotton.

[0040] The first step, polyester fiber treatment: the treatment process is followed by cleaning, carding and pre-merging. Among them, the cleaning process adopts the principle of short process and light blow to reduce the damage and rubbing of polyester fibers; the carding process, according to the polyester fiber In order to ensure the carding and smooth transfer of polyester fibers, take appropriate measures to lighten the weight of raw sliver and reduce the speed of doffer. The weight of raw sliver is set at 22g / m, and the speed of doffer is 32r / min;

[0041] The second step, combed cotton treatment: the treatment process is followed by blowing carding, pre-merging, sliver winding and combing. Doffer speed, doffer speed is 34r / min, imported Graff card clothing is used to increa...

Abstract

The invention relates to novel polyester cotton blended yarn and a production process thereof. The novel polyester cotton blended yarn comprises positive ion upgraded modified polyester fibers and combed cotton, and the novel polyester cotton blended yarn is fixed by evenly mixing 65% of the polyester fibers and 35% of the combed cotton. The polyester cotton blended yarn adopts the positive ion upgraded modified polyester fibers and the combed cotton for blending. The production process comprises the steps of processing of the polyester fibers, processing of the combed cotton and blending of the polyester fibers and the combed cotton. The novel polyester cotton blended yarn has the advantages of being high in yarn levelness, little in yarn hairiness, soft in hand feeling and the like. Fabrics made of the novel polyester cotton blended yarn can be dyed through a normal pressure boiling dyeing process, production costs are greatly saved, the degree of dyeing is high and can reach 97%, and the novel polyester cotton blended yarn is bright in color, can be dyed in dark colors easily, is high in wash fastness and rubbing fastness and is much better than ordinary homogeneous yarn on the aspect of resistance to pilling.

Description

technical field [0001] The invention relates to the technical field of textile product production methods, in particular to a novel polyester-cotton blended yarn and a production process thereof. 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 shortcoming that above-mentioned polyester-cotton fabric exists is: [0004] (1) Due to the characteristics of ordinary polyester fibers, the dyeing rate is low, and a "high temperature and high pressure" dyeing process i...
