Abstract

The invention relates to a method for preparing suedette elastic fabric. The method comprises the following steps that 1, weaving processing is conducted on raw materials by taking polyester or polyester sea-island type ultra-fine denier fiber filaments as the warp direction and taking polyester woven spandex filaments as the weft direction; 2, open-width scouring, preshrinking, preshaping, decrement, dyeing, sanding, napping, shearing and shaping are conducted on gray fabric obtained in the first step, wherein open-width scouring comprises the steps that low temperature scouring is conducted for 30-120 min through cold water with the temperature ranging from 20 DEG C to 35 DEG C, then scouring is conducted for 20-30 min in warm water with the temperature ranging from 60 DEG C to 70 DEG C, and high-temperature processing is conducted for 8-15 min through hot water with the temperature ranging from 90 DEG C to 98 DEG C. Therefore, uniform shrinkage of spandex in a wet state is guaranteed, and the warp density is increased. The preparation method is simple, convenient and feasible, the raw materials are easy to obtain, the cost is low, and the product quality is good.

Description

A kind of method prepared by Glove suede stockinette

Technical field

The invention belongs to textile technology field, particularly a kind of method prepared of Glove suede stockinette.

Background technology

Natural suede suede gloss is soft, quality is soft, feel is fine and smooth comfortable, very popular.But muntjac quantity is extremely limited, suede nap is more aobvious famous and precious.Along with the development of leather tanning technology, sheepskin, ox-hide and pigskin etc. can have been done matte processing by current people, and this leather products is also referred to as suede nap traditionally.But the suede nap price adopting sheepskin and ox-hide to process is still very expensive, and produce quantitative limitation by it, little a part of human needs can only be met.The suede nap seen in the market is some flock suede fabrics mostly.The main raw material of flock suede fabric is sea-island composite fiber, and woven fabric, knitted fabric and non-weaving cloth all can as the Ji Bu of flock suede, and wherein, knitted fabric has again through compiling and the dividing of weft knitting.Be at present that the dyeing and finishing technology of the flock suede grey cloth of base cloth has following two kinds with knitted fabric:

1, through compiling grey cloth → plucking → cropping → preboarding → concise, lax, Alkali reduction (fibrillation) → dyeing → reduction cleaning → preboarding → napping → Final finishing → setting → finished product

2, weft-knitted grey cloth → concise, lax, Alkali reduction (fibrillation) → dyeing → reduction cleaning → cut open width → preboarding → bristle napping → Final finishing → setting → finished product

Adopt sea-island composite fiber to be that the flock suede fabric elasticity that raw material obtains is poor, therefore have producer to attempt introducing the elastomers such as spandex in grey cloth in recent years.In general, the elastomers such as spandex are in braiding process, accident in order to avoid spandex thread extend and tension force uneven and affect the quality of stockinette, spandex thread must adopt special fixed-length positive formula line feeding device to yarn, strictly controlling the defeated line tension of spandex thread when giving yarn well simultaneously, there is certain difficulty when implementing suitability for industrialized production.

Summary of the invention

Technical problem to be solved by this invention overcomes deficiency of the prior art and provides a kind of suitability for industrialized production simple and feasible, and raw material is easy to get, and cost is low, the production method of the Glove suede stockinette of good product quality.

To achieve these goals, the present invention adopts following technical scheme: a kind of method prepared by Glove suede stockinette, comprises following key step:

(1) raw material adopts and washs/wash fabric of island-in-sea type superfine Denier fibre long filament as warp-wise, and terylene intertexture spandex filament carries out weaving processing as broadwise, and its weaving plan is as follows: warp-wise: wash/wash fabric of island-in-sea type superfine Denier fibre long filament FDY → twisting → setting → warping; Broadwise: wash FDY+ spandex → twisting → setting → whole latitude, carries out longitude and latitude afterwards and is woven into grey cloth;

(2) grey cloth that step (1) obtains is carried out following operation: open-width scouring → preshrunk → preboarding → decrement → dyeing → sanding → plucking → cropping → setting; Described open-width scouring first carries out the concise 30-120min of low temperature with the cold water of 20-35 DEG C, then at the concise 20-30min of the warm water being warming up to 60-70 DEG C, afterwards at the hot water high-temperature process 8-15min with 90-98 DEG C, thus ensure that spandex uniform shrinkage under wet condition puies forward high sley; When described low temperature is concise, concise bath comprises the dispersion degreaser of NaOH and 30g/L of 5-20g/L, and described dispersion degreaser is with parts by weight, composed of the following components:

N butyl oleate sodium sulfonate 20-30

Alkyl polyoxyethylene derivative 15-18

Polyox-yethylene-polyoxypropylene block copolymer 12-16

Sodium chlorite 3-7

Polyacrylamide 2-8

Fatty alcohol sulfate single ethanol ammonium salt 0.5-3

Di-n-octyl sebacate 10-20

Ethoxylated dodecyl alcohol phosphate 2-5

Ethanol 30-50

Deionized water is about 80-100;

Adopt described dispersion degreaser can control the reduction rate of latitude bullet Glove suede stockinette between 8-12%, make the Glove suede stockinette prepared have good feel and elastic force.

Preferably, the time preferred 60min that described low temperature is concise.

Preferably, middle warm type levelling agent is added in described dyeing course.

The present invention compared with prior art has the following advantages:

The present invention, by adopting the concise mode of low temperature, decreases the damage of washing ammonia fiber, makes the tinctorial yield indifference of fiber when dyeing, and makes fabric have good pendency sense and elegant sense; The dispersion degreaser of specific composition that the present invention adopts eliminates the longer loose fibre in yarn bundle surface, has carried out micro-fibrillation to the surface of polyster fibre and spandex fibre simultaneously, and what make fabric organizes that skin texture is clear, nature, exquisiteness.
