A kind of method utilizing vacuum type setting process to prepare viscose face fabric
Technical field
The invention belongs to textile technology field, a kind of utilize vacuum type setting process to prepare viscose face fabric
Method.
Background technology
Viscose rayon, a principal item of staple fibre;Alkali cellulose is formed through alkalization by native cellulose, then with two
Nitric sulfid effect generates cellulose xanthate ester, and the viscous solution obtained in being dissolved in sig water claims viscose glue, and viscose glue is through Wet-spinning
Silk and a series for the treatment of process after viscose rayon;Viscose rayon is again artificial silk, ice silk, and after 2000, viscous fibre occurs again
A kind of entitled tencel, the high-grade new varieties of bamboo fibre;Viscous fibre is with cotton or other natural fiber cellulose as raw material production
Fiber;In 12 kinds of main textile fabrics, viscous fine moisture percentage best suits the physiological requirement of human body skin, have smooth nice and cool,
The characteristics such as ventilative, antistatic, dyeing are gorgeous.
But due to the attribute that viscose rayon fiber itself is intrinsic: fiber is more fluffy, and ultimate fibre is the most crisp, can weave
Property poor, exist when making fabric and be much difficult to the problem that overcomes such as: fiber is more fluffy, and between fiber, cohesive force is poor, is spinning
Easily occur in journey that electrostatic is more serious, filoplume is more, the easy adhesion of fiber, web easily drop, easy blocking horn mouth etc., can't apply
In the textile of daily life.
It is that fiber or yarn are carried out humid heat treatment that yarn steaming processes, and appropriate humid heat treatment is to fiber and the physics of yarn
Mechanical performance all has a certain impact.After fiber absorbs moisture, can release heat, now, fiber molecule warm-up movement weakens, internal
Structural stability strengthens, and will be in order to keep continuing of this state, it is necessary to gives yarn a certain degree of heat compensation, makes cylinder
Sub-yarn ectonexine can be contributed to improving the overall performance of yarn by equal heat treatment.
Summary of the invention
The technical problem to be solved is, the shortcoming overcoming prior art, it is provided that it is fine that one can strengthen viscose glue
Cohesive force between dimension weaving face fabric fiber, reduces electrostatic, and that improves viscose rayon textile overall performance utilizes vacuum type sizing work
Skill prepares the method for viscose face fabric.
In order to solve above technical problem, the present invention provides one to utilize vacuum type setting process to prepare viscose face fabric
Method, selection through weft material be according to the mass fraction: viscose rayon 40-90 part, combed cotton 20-40 part, super fine denier is washed
Synthetic fibre 8-18 part, the preparation section of fabric lining is scutching cotton, comb and parallel cotton fibers prior to spinning, drafting, rove, spun yarn and weaving operation, wherein: operation of weaving cotton cloth
Include warping, Vacuum shaping, sizing and jet operation;
Vacuum shaping concretely comprises the following steps:Being pushed by fabric in steaming silk case and water filling in case, water injection rate controls as not have
/ 3rd of fabric height, silk case is steamed in preheating makes its internal temperature reach 20-35 DEG C;Utilize water ring vacuum pump in casing
Carry out evacuation for the first time, and box house is heated so that low-temperature saturated steam is penetrated in fabric, heat 0.6-
0.8h keeps case body temperature to stand 45-50min after reaching 80-90 DEG C;Casing after standing is carried out second time evacuation,
And again inside heating compartment, heat time heating time, 30-45min, kept case body temperature to be 86-95 DEG C;Heating is incubated after terminating
And stand 25-30min, i.e. complete the Vacuum shaping of fabric.
Technique effect: owing to the present invention uses above technical scheme, it is that fiber is carried out damp and hot place that Vacuum shaping processes
Reason, appropriate humid heat treatment, to the effect of having greatly improved of the physical and mechanical properties of fiber, after fiber absorbs moisture, can release heat
Amount, now, fiber molecule warm-up movement weakens, and internal structure stability strengthens, and now gives yarn a certain degree of heat compensation,
Keep continuing and stable of this state, make yarn ectonexine can be significantly improved the overall performance of yarn by equal heat treatment.
The technical scheme that the present invention limits further is:
Further, the aforesaid method utilizing vacuum type setting process to prepare viscose face fabric, Vacuum shaping is concrete
Step is:Being pushed by fabric in steaming silk case and water filling in case, water injection rate controls as not have 1/3rd of fabric height, in advance
Heat steams silk case makes its internal temperature reach 28 DEG C;Utilize water ring vacuum pump to carrying out for the first time evacuation in casing, and to case
Body is internally heated so that penetrated into by low-temperature saturated steam in fabric, and heating 0.7h keeps case body temperature to reach 85 DEG C
Rear standing 48min;Casing after standing is carried out second time evacuation, and again inside heating compartment, heat time heating time
36min, keeping case body temperature is 90 DEG C;Heating is incubated after terminating and stands 26min, i.e. completes the Vacuum shaping of fabric.
The aforesaid method utilizing vacuum type setting process to prepare viscose face fabric, in comb and parallel cotton fibers prior to spinning step: viscose rayon
Kun woods, licker-in speed ratio are 2:3, and spacing of cylinder flat is 0.15 mm, weight of card sliver 16-18 g/5m;Superfine denier polyester comb and parallel cotton fibers prior to spinning
Kun woods, licker-in speed ratio be 2.2:2.5, spacing of cylinder flat is 0.1 mm, weight of card sliver 16g/5m.
The aforesaid method utilizing vacuum type setting process to prepare viscose face fabric, the quantification of 4.2g/10m of rove,
Percentage elongation is 1.00-1.20%.
The aforesaid method utilizing vacuum type setting process to prepare viscose face fabric, in spun yarn step, back area draft times
Number is 1.31, and yarn twist factor is 380, and ingot speed is 16000r/min;In winder step, speed is 1000m/min, and pressurize 6-
10N。
