Classification and Characteristics of Dyeing Fastness of Twill Fabrics

- May 22, 2018-

The weft yarns and warp yarns of the twill weave fabric are interweaved at least once between two yarns in a certain degree. In the process of operation, they are effectively used to add the warp and weft intertwining points, and to a certain extent effectively change the structure of the fabric structure. To a certain extent, they can be collectively referred to as twill fabrics.

Twill fabrics can be effectively divided into two on the twill, in the production of cars in the front diagonal lines is very obvious, the number of warp and weft yarns are close, the density is slightly higher than the weft density, feel than Khaki is soft.

Twill fabric dyeing fastness classification

1. Light fastness, generally refers to the degree of discoloration of a colored fabric to a certain extent by the effect of its sunlight, the test method can be used directly in the sun when it is operating According to the sun, the degree of fading of the sample after exposure to sunlight was compared with the standard color sample. The sample was divided into 8 grades, with grade 8 being the best and grade 1 being the worst. Clothing fabrics with poor light fastness should not be exposed to sunlight for a long time and should be dried in a ventilated place.

2. The crocking fastness, in the process of making, mainly refers to the degree of effective discoloration of the dyed fabric after it has been rubbed. To a certain extent, it can be effectively divided into its wet friction and dry friction. The degree of whiteness is evaluated by the degree of white cloth staining, which is divided into 5 levels (1 to 5). The larger the value, the better the fastness to rubbing. The life of fabrics with poor crocking fastness is limited.

Twill fabric features

The twill fabric will have its positive and negative aspects to a certain extent. In the process of operation, there is less interweaving point within a complete tissue cycle, and when it is used, the float line is longer and feels soft, during the process of production. The tissue density of the tissue is high, the product is relatively thick, and the tissue has a strong three-dimensional effect. There are 30, 40, and 60 counts.

The twill weave fabric uses polyester DTY75D yarn and Jindi compound 160D as the material. We choose diagonal weave and weaving on the water jet loom. We have successively made a series of finishing processes such as dyeing and finishing. This cloth width is 150cm, weighing about 120 grams per meter, suitable for the manufacture of men and women trousers, casual wear and women's skirts and other clothing, into the upper body.
