Abstract
A water-soluble paper used as draft of embroidery is made up of soluble polyvinyl alcohol fibres through shaping, dripping water, squeezing, and vacuum drying. Its advantages are uniform strength, low cost, and high effect to improve quality of embroidery.
Description
Technical field
What the present invention relates to is that synthetic fiber are the paper of raw material, particularly the paper made from polyvinyl alcohol.
Background technology
Because polyvinyl alcohol (PVA) fiber can dissolve in hot water, thereby can be as the aspects such as nonwoven fabric (Wang Jizu etc. " application of nonwoven product and design " version P68 in 1994 of China Textiles Press) of embroidery cloth.Generally adopt this fiber to make water-soluble interlaced fabric (being commonly called as nonwoven fabric) at present both at home and abroad, the base fabric when producing embroidery lace, lace etc. as machine embroidery.Promptly embroidered various decorative patterns, the lace of pattern, lace on this water-soluble base fabric carry out water treatment with it then, make base fabric soluble in water, and beautiful lace, lace are handled the back in drying, ironing etc.This nonwoven fabric is produced with infusion process, and the technological process of production is: feed cotton → carding → foaming → impregnation → drying → rewinding.There are many shortcomings in the nonwoven fabric of producing, as the big and transverse strength little (longitudinal fracture intensity is horizontal 1.4～1.7 times) of longitudinal strength; The quality uniformity is very poor (to be reached ± 6g/m
2More than), can see that cloth cover has many heap because of fiber density to be listed as the irregular point and the piece that differ in size, eedle is grabbed incessantly base fabric at the sparse local line of fiber when machine embroidery, and decorative pattern, pattern have just had defective, and product just becomes substandard products, makes yield rate reduce.In addition, this nonwoven production efficient is not high, and production cost is not low.
Summary of the invention
The objective of the invention is is main raw material with the solubility vinal still, makes water-soluble paper with the method for papermaking, substitutes the base fabric of nonwoven fabric as machine embroidery, overcomes the above-mentioned shortcoming that nonwoven fabric exists simultaneously.
The present invention program is: be raw material with the water-soluble polyvinyl alcohol fibers, add the paper grade (stock) auxiliary material and make paper pulp, copy the paper drainage, form through press dewatering, drying, rewinding with copying the online of paper equipment.The length of PVA staple fibre is 2～16mm, with 2～8mm for well, can be with single length, with can be, better with 2 kinds of fiber arranging effects different in size with (the comprising mixing length) of length more than 2 kinds or 2 kinds; The PVA fiber is insoluble in cold water in addition, dissolve in 60～98 ℃ of hot water, the mixed with fibers that therefore all lengths of different temperatures dissolving is arranged, both made and when slurrying, do not added bonding agent, fiber also is dissolved under its solution temperature on the undried paper in the remaining water when dry, along with dry run is carried out insoluble fiber to be bonding to and become finished paper.The slurrying of the water soluble paper processing of need not pulling an oar, but fiber very easily wadding is poly-again, poly-in heaps easily, form piece, so must add dispersant.The purposes of the water soluble paper stipulates that it must be dissolved in the hot water, so the dispersant of the insoluble in water of paper grade (stock) commonly used can not use, some natural extracts and converted products thereof can be used, as starch and processed goods, Sodium Alginate etc.; The synthesis of soluble macromolecular material can be used as desirable dispersant, and as polyvinyl alcohol, carboxymethyl or carboxyethyl cellulose and sodium salt, polyacrylamide etc., a kind of in available the above kind also can two kinds share.Particularly PVA is similar with main material, uses better.In the molten sub-hot water of dispersant, use the cooling back.The dispersant use amount is decided on fiber length, is controlled at 0.1～2.0% more suitable.Can add bonding agent in the paper pulp, also need be water miscible, as PVA, vinyl acetate etc., and PVA is ideal.Therefore PVA be dispersant be again bonding agent, and to white water recycle in the later production again with being favourable.The control of copying paper temperature and baking temperature is need look to use PVA fiber temperature and fiber length to decide, too high easy one-tenth PVA film and can't using, cross low then running difficulty, the paper product bonding is bad, intensity difference generally is controlled at 45～55 ℃, does not add bonding agent, and when dissolving the prescription that plays cementation in the back and produce by part PVA fiber, the quality of paper can be relatively poor.Copy the paper drainage and can use fourdrinier, cylinder machine or other form net machines, be advisable with cylinder equipment.If after this step of press dewatering, increase vacuum dehydration, its moisture is further reduced, effect is also good.This paper of the present invention, papery is even to the eye, and feel is better; Printing opacity sees not had tangible blank spot and blank block, and the intensity of vertical and horizontal is very consistent, and fracture strength can reach 〉=70N/5cm; Its uniformity is also fine, can reach≤± 1.5g/m
2, water-insoluble≤5%.Because the difference of papermaking and nonwoven production equipment and technology, and ingredient requirement difference, the production efficiency of the water soluble paper are apparently higher than the latter, and production cost also has decline significantly.
When being used for machine embroidery and producing embroidery lace, lace as base fabric, water-soluble paper of the present invention is than the advantage of soluble non-woven fabrics: (1) product quality greatly improves: vertical, horizontal intensity consistent and uniform degree is good, makes the embroidery product yield rate increase substantially; (2) production efficiency height, water-soluble paper are 2 times of soluble non-woven fabrics; (3) cost descends significantly, about drop by half.Therefore, the superiority that the present invention had is
Prior art can't be compared.
The specific embodiment
Long 2～10mm the mixing length of example 1 usefulness, 70 ℃ of water-soluble PVA fibers, 1%60 ℃ of water-soluble PVA solution are discrete bond agent slurrying 300t, copy the paper drainage in fourdrinier wire, copy 45～50 ℃ of paper temperature, and through press dewatering, baking temperature is 60 ± 2 ℃, and rewinding becomes paper.Paper is more even, and printing opacity is seen does not have obviously bright or big bright spot, and the vertical and horizontal fracture strength is respectively: 85 and 70N/5cm, and the uniformity ± 1.5g/M
2The paper insoluble matter is＜4%.
Example 2 PVA fibers are used 60 ℃ and the slurrying of 70 ℃ of water-solubility PVA fibers of long 4mm and 8mm (each 50%) respectively, wherein adding concentration is 1%60 ℃ of water-soluble PVA solution (the PVA dosage is 1.2%), cylinder is copied the paper drainage, the press dewatering final vacuum blots, and dryer temperature is controlled at 50 ℃ ± 1 ℃ when dry.Papery is even, the heavy 60g/M of paper
2, the uniformity ± 1g/M
2, vertically, transverse strength is respectively＞120N/5cm and＞100N/5cm.Paper insoluble matter＜3%.
3 60 ℃ of water-soluble PVA fibers of example (long 4mm), 80 ℃ of water-soluble PVA fibers (long 4mm) account for 40% and 60% respectively, use the carboxymethyl cellulose dispersant, dosage 0.12%, cylinder is copied 48 ± 2 ℃ of paper drainage paper temperature, and it is even to get water-soluble paper after the drying, the uniformity ± 1g/M
2, the heavy 56g/M of paper
2, tensile strength 0.71KN/M, insoluble matter＜5%.
Example 4 lists are made dispersant with long 8mm, the slurrying of 70 ℃ of water-soluble PVA fibers with 1.5%60 ℃ of water-soluble PVA solution, and other adds 0.1% polyacrylamide, the gravity mechanical agitation, and cylinder is copied paper (50～54 ℃), after the drying, the heavy 50.5g/M of paper
2, tensile strength 0.47KN/M, insoluble matter＜5%.
