Abstract
The invention belongs to the technical field of fabric processing, and more concretely relates to a preparation method of spandex-free elastic cloth. The preparation method comprises the following steps: 1) selecting materials comprising the following materials by weight: 75-80 parts of stretch polyester, high stretch yarn terylene, stretch nylon yarn or high stretch nylon yarn, and 20-25 parts of monofilament; 2) refining at a low temperature; 3) pre-shaping: controlling the pre-shaping temperature at 200 DEG C; 4) dyeing; 5) reducing and cleaning; 6) shaping; and 7) packaging. In the preparation method of spandex-free elastic cloth, the stretch yarn is of a 'w' shape originally and is straightened during weaving; low temperature refining makes the straightened yarn back to 'w' shape; the yarn keeps the 'w' shape during shaping so that the fabric is elastic.
Description
Technical field
The invention belongs to fabric processing technique field, be specifically related to a kind of preparation method without elastomeric polyurethane fiber cloth.
Background technology
Pure-cotton fabric has plurality of advantages, as good permeability, softness etc., but creases easily and not easily nurses, generally for and reach certain flatness effect, need employing to add resin ironing-free technology; Polyester-cotton fabric is more containing terylene component, and moisture pick-up properties is poorer, more easily plays electrostatic, feel and snugness of fit and declines; In order to make fabric have elasticity, usually adopt the method adding spandex, but there will be " tangerine peel " phenomenon after having the fabric of spandex to wash, very do not scrape crease easily, powerful lower degradation.Add resin ironing-free technology and add spandex and obtain elasticity, both increase cost.
Low elastic polyester filament (Drawtexturingyarn, be called for short DTY) be a kind of textured filament type of terylene chemical fibre, it is with polyester slice (PET) for raw material, adopts and spins terylene pre-oriented fiber (POY) at a high speed, then process through drafting false twisting.There is the features such as flow process is short, efficiency is high, quality is good.It, except the feature such as have general terylene fracture strength and elastic modelling quantity is high, heat setting is excellent, rebound performance is good, heat resistance, light resistance, corrosion resistance are strong, quick-drying washable, also has the features such as bulkiness is high, thermal insulation good, comfortable feel, gloss are soft.
Summary of the invention
Technical problem to be solved by this invention is: the invention provides and a kind ofly do not add the preparation method without elastomeric polyurethane fiber cloth that spandex reaches same elastic effect.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is:
A kind of preparation method without elastomeric polyurethane fiber cloth is provided, comprises the steps:
1) raw material is chosen: described raw material comprises the material of following weight part ratio: low elastic polyester filament (light net, middle net, heavily net), POLYESTER HIGH ELASTIC YARN or nylon stretch yarn (light net, middle net, heavily net) or polyamide fibre false-twist textured yarn 75-80 part, monofilament 20-25 part;
2) low-temperature refining: the raw material of step 1 is placed in dye vat refining, temperature controls as 50-60 degree, refining time is 10-15 minute, containing accounting for the auxiliary agent that in dye vat, solution quality percentage is following in described dye vat: soda ash 2-3%, degreaser 1-2%, glacial acetic acid 0.5-1%, moisture absorbing and sweat releasing agent 3-5%;
3) predetermined; Controlling predetermined temperature is 200 degree;
4) dye;
5) reduction cleaning;
6) Cheng Ding;
7) pack.
Beneficial effect of the present invention is: 1, the present invention is " W " shape without low-stretch yarn yarn in the preparation method of elastomeric polyurethane fiber cloth originally, be straightened in woven process, and low-temperature refining makes the yarn be straightened return to the state of " W ", afterwards when sizing, keep the state of this " W ", so just make cloth cover be full of elasticity; 2, the raw material of preparation method of the present invention is not containing spandex, and during dyeing, (COLOR FASTNESS of terylene own is good can to prevent excessive look, excessive look can not be produced, and the spandex only temporary absorbing dye of meeting itself, wait after a time, yarn is tired, and spandex just there will be the phenomenon that fades, thus produces the look that overflows).3, preparation method of the present invention greatly reduces production cost and reaches the effect of energy-saving and emission-reduction.
