Problems solved by technology

However, compared with ordinary polyester, cationic modified polyester has lower strength, poor acid and alkali resistance, especially sensitive to strong alkali, and the hydrolysis rate under the action of strong alkali is 2-3 times higher than ordinary polyester fiber; in addition, The heat resistance of cation-modified polyester is poor, and the temperature of the fabric during high-temperature setting treatment should be moderately low, not higher than 160°C; finally, the price of cation-modified polyester is also higher than that of ordinary polyester fiber

Embodiment 1

[0026] The invention provides a technical solution: a method for preparing a piece-dyed wool normal-pressure dispersion-dyeable polyester blended fabric with high efficiency and short flow. The specific steps are as follows:

[0027] 1. Atmospheric pressure disperse dyeable polyester stretch-cut strips: Introduce dimethyl isophthalate with polar group SO3Na into polyester chips and spin them into filaments, and then bundle, stretch, wash, and coat After a series of processes such as oiling, crimping, drying and shaping, the polyester filament bundles are broken into short fibers of unequal length by two pairs of rollers with different speeds on the stretcher, and finally the short fibers are combed into strips through the strip making process. .

[0028] 2. Yarn forming method: mix and draft the normal-pressure disperse dyeable polyester stretch-cut fiber strips and pure wool tops or other fiber strips according to the proportion required by the process in step 1 to form low-t...

Embodiment 2

[0032] The invention provides a technical solution: a method for preparing a piece-dyed wool normal-pressure dispersion-dyeable polyester blended fabric with high efficiency and short flow. The specific steps are as follows:

[0033] Stretching and cutting the modified polyester filaments which are dispersible and dyeable under normal pressure into strips to obtain polyester wool tops;

[0034] Select 10% modified polyester tops, mix them with pure wool tops or blended tops, mix and draw through the combing process to obtain low-temperature dyeable wool polyester thick strips, and then go through roving, spun yarn, winding, and Low-temperature dyeable wool polyester blended yarns are produced through thread, two-for-one twisting, and steamed yarn setting processes; among them, the blended sliver includes cotton, silk, hemp, viscose, cupro, acetate, modified polyester, and nylon.

[0035] Use low-temperature dyeable wool polyester blended yarn to complete the weaving process to...

Abstract

The invention discloses a piece-dyed wool normal-pressure dispersion dyeable polyester blended fabric and a preparation method thereof, and the preparation method comprises the following steps: stretching and cutting low-temperature dyeable modified polyester filaments into strips to obtain modified polyester wool tops; the method comprises the following steps: selecting not less than 10% of modified polyester wool tops, mixing the modified polyester wool tops with pure wool tops or blended tops, carrying out mixed drawing and drafting through a recombing process to obtain low-temperature dyeable wool polyester coarse tops, and then carrying out roving, spinning, spooling, doubling, two-for-one twisting and yarn steaming and shaping processes to produce the low-temperature dyeable wool polyester blended yarns. Finishing a weaving process by using low-temperature dyeable polyester blended yarns to obtain grey cloth; after pre-shaping, dyeing and finishing processing technologies such as continuous boiling, one-bath piece dyeing and wool finishing are carried out, and the wool polyester blended fabric is obtained. The method has the advantages of low cost, high efficiency, short process, rapid color proofing and the like.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a piece-dyed wool normal-pressure disperse-dyeable polyester blended fabric and a preparation method thereof. Background technique [0002] At present, since polyester fiber needs to be dyed under high temperature and high pressure at 130°C, while wool fiber is dyed under normal temperature and pressure at 60°C, the one-bath dyeing of the two will cause serious damage to the wool fiber; at the same time, due to the smooth polyester fiber and the scale layer The difference in the reflective properties of the wool fiber surface to light leads to a large difference in color and light between the two. It needs to be evenly mixed to avoid the phenomenon of different colors and variegated colors of the finished fabric. Therefore, in order to avoid damage to the wool and give the fabric a good color consistency, the wool / polyester blended fabrics are all made of the traditional strip d...
