Problems solved by technology

Loose fiber or top dyeing, the two fibers do not affect each other, the dyeing effect is better, but the two fibers are dyed separately, the dyeing process is long, which is not conducive to energy saving and emission reduction
Moreover, the batch requirement for dyeing first and then spinning is large, which is not suitable for the current development of small batches of multi-variety products.

[0096] The structural formula of the modified polyester has the following structural units:

[0097]

[0098] where 101 2 3 4 <5.

[0099] Fabric structure: basic organization——A: four pieces of warp surface broken twill; B: four pieces of weft surface broken twill dobby weaving, A and B tissue form a rectangular lattice distribution on the fabric.

[0100] Process flow: Prepared according to the preparation method of blended fabrics commonly used in this field, the process flow includes warping - sizing - drawing and reeding - weaving - gray cloth - dyeing and finishing - finished product

[0101] The woven fabric is dyed using four schemes to obtain different fabric effects.

[0102] Dyeing scheme (1): Dyeing with acid dyes only

[0103] Dyeing process:

[0104] Ellinier black AM-R2.0%, leveling agent 0.5g / L,

[0105] Glacial acetic acid ...

Embodiment 2

[0127] Example 2: Fabric Product Two

[0128] Combination of fabric raw materials: warp yarn - modified polyester 20 S

Abstract

The invention relates to a modified polyester and wool blended fabric and a preparation method thereof. The blended fabric is formed by blending and spinning modified polyester and wool. The modified polyester has the following structural unit, wherein m1 is more than 1 and less than 160; m2 is more than 1 and less than 70; m3 is more than or equal to 0 and less than 20; and m4 is more than or equal to 0 and less than 20. In the blended fabric, the modified polyester accounts for 5 to 80 percent. The blended fabric is formed by weaving one or more modified polyester and wool blended yarns of which the blending ratios are different. In a weaving process, the fabric structure is pre-designed and the blended fabric is subjected to one bath dyeing with an acidic dye and a disperse dye in the environment of which the temperature is less than 100 DEG C and the pH value is between 2 and 6. Both the plain colour effect of the same colour of the whole fabric and the fancy effect similar to a dyed fabric can be realized.

Description

technical field [0001] The invention relates to a fabric and a preparation method thereof, in particular to a modified polyester and wool blended fabric and a preparation method thereof. Background technique [0002] Polyester and wool blended fabric is a traditional fabric variety and an important fabric product type. It combines the main advantages of polyester and wool, has good resilience and wrinkle resistance, and partially retains the characteristics of pure wool fabrics. , and effectively reduce the manufacturing cost of the fabric. [0003] The Chinese patent application whose application number is 200710121949.7 discloses a polyester and wool blended fabric and a preparation method thereof. The polyester and wool blended fabric is composed of 30%-50% wool, 45%-20% polyester fiber, 10 %-35% solution dyed or strip dyed PTT or PET / PTT polyester composite short fiber blended. The fabric has better wool feeling, 5-25% tensile elasticity, and lower cost than other wool...
