Abstract
The invention discloses anti-crease finishing liquid suitable for pure cotton fabric. The anti-crease finishing liquid is prepared from, by weight, 5-9 parts of fibroin finishing liquid, 2-6 parts of sulfonic-carboxylic acid type water-soluble polyurethane, 0.1-1 part of hydroxyethyl acrylate and 200 parts of deionized water. When applied to the pure cotton fabric, the anti-crease finishing liquid can achieve a good anti-crease effect, and the pure cotton fabric keeps the advantages of good handfeel and wearing comfort; besides, the anti-crease finishing liquid is safe and environmentally friendly and will not release formaldehyde.
Description
Technical field
The present invention relates to pure cotton fabric technical field of modification, be specifically related to a kind of anti-crease finishing liquid being applicable to pure cotton fabric.
Background technology
Pure-cotton fabric take cotton as raw material, through the fabric that textile technology is produced, has the features such as moisture absorption, moisturizing, heat-resisting, alkaline-resisting, health.Pure-cotton fabric is comfortable and easy to wear, skin-friendly good, is subject to the extensive favor of people, especially in infant clothing, is regarded as safest fabric.But pure cotton fabric elasticity is poor, in dress and washing process, easily wrinkling and distortion, needs often to press or carry out anti-crease finishing.At present, the more crease-shedding finishing agent of industrial application is resin finishing agent, but this kind of finishing agent production cost is higher, and easily discharges formaldehyde in dress and use procedure.Formaldehyde is a kind of poisonous chemicals, a kind of skin irritant and allergic agent, can severe irritation eyes, skin and mucous membrane, especially a kind of carcinogenic material.Therefore, a kind of crease-shedding finishing agent that is safe, nontoxic, environmental protection being applicable to pure cotton fabric is developed extremely urgent.
Summary of the invention
The invention provides a kind of anti-crease finishing liquid being applicable to pure cotton fabric, pure cotton fabric can be applied to and obtain good anti-wrinkle effect, and the advantage keeping the feel of pure cotton fabric good, comfortable and easy to wear; In addition, this anti-crease finishing liquid also safety and environmental protection, not Diazolidinyl Urea.
Technical scheme of the present invention is as follows:
Be applicable to an anti-crease finishing liquid for pure cotton fabric, comprise following component with weight portion note:
Fibroin liquid 5 ~ 9 parts;
Sulphur carboxylic acid type soluble polyurethane 2 ~ 6 parts;
Hydroxy-ethyl acrylate 0.1 ~ 1 part;
Deionized water 200 parts.
Preferably, a kind of anti-crease finishing liquid being applicable to pure cotton fabric, comprises following component with weight portion note:
Fibroin liquid 7 parts;
Sulphur carboxylic acid type soluble polyurethane 4 parts;
Hydroxy-ethyl acrylate 0.5 part;
Deionized water 200 parts.
A kind of preparation method being applicable to the anti-crease finishing liquid of pure cotton fabric of the present invention comprises the steps:
(1) silk is padded in the sodium carbonate liquor of 2g/L, carry out degumming process, then cold water washing post-drying;
(2) calcium chloride solution, deionized water and absolute ethyl alcohol are become mixed solution with the proportions of 1:7:2, process the Silk Soaking after coming unstuck in mixed solution by through step 1, at 70 DEG C, place 3h;
(3) substance transfer step 2 obtained, in NF membrane, through deionized water dialysis, removes Ca
2+, Cl
-ion, then through charcoal absorption, filtration, obtain fibroin liquid;
(4) fibroin liquid step 3 obtained mixes with sulphur carboxylic acid type soluble polyurethane, hydroxy-ethyl acrylate and deionized water, and ultrasonic agitation 90min obtains the anti-crease finishing liquid being applicable to pure cotton fabric.
The present invention has following technique effect:
Fibroin liquid in the present invention is widely used in the crease-resistant process of real silk fabric in recent years, and achieves good result.But in fibroin molecular structure lack can with the group of cotton fiber generation covalent cross-linking, if be therefore applied to separately poor effect in the crease-resistant process of pure cotton fabric; In order to address this problem, introduce sulphur carboxylic acid type soluble polyurethane in anti-crease finishing liquid of the present invention, there is deblocking reaction in this material, obtain the performed polymer that end group is-NCO under high temperature action, and cotton fiber is formed the film with cross-linked structure; On the other hand ,-NCO has very high reactivity, can react with the hydroxyl on cotton fiber, the amino groups on Fibroin Finishing Agent, improves the adhesion of finishing agent and cotton fiber.Hydroxy-ethyl acrylate is also added as crosslinking agent in the present invention, can at line style intermolecular bridging action, thus make the mutual bonding cross-linking of relevant group in cotton fiber, Fibroin Finishing Agent and polyurethane reticulate the material of structure, further enhance the crosslinked action between dressing liquid and cotton fiber.
Anti-crease finishing liquid in the present invention not only can improve the crease-resistant recovery angle of pure cotton fabric, can also keep the soft feel of pure cotton fabric.Iron-free finishing process of the present invention effectively can also keep ultimate strength and the Tear strength retention rate of purified cotton cloth, ensures its useful life longevity.In addition, anti-crease finishing liquid safety non-toxic of the present invention environmental protection, formaldehydeless release.

embodiment 12
Anti-crease finishing liquid and the traditional resin finishing agent (comparative example) of pure cotton fabric being put into respectively embodiment 1-11 pad post-drying washing, then naturally dry, to carry out performance test; In addition, also have chosen without anti-crease finishing liquid process pure cotton fabric as a comparison case.
Its wrinkle recovery angle of woven fabrics using viscoelasticity theory is measured to weigh the wrinkle resistance of fabric to above-mentioned treated pure cotton fabric.During mensuration, according to GB GB/T3819-1997, horizontal folding fabric method AATCC crease recovery of fabrics tester is adopted to test.
Pure cotton fabric before and after process is carried out to the test of breaking strength retention, test, with reference to GB GB/T3923.1-2013, is surveyed pure cotton fabric 5 through 5 latitudes, is averaged respectively; Fabric tear strength test is carried out to the pure cotton fabric before and after process, with reference to GB GB/T3917.1-2009, surveys pure cotton fabric 5 through 5 latitudes, average respectively.The durability of these two tests in order to assess fabric.
Above-mentioned test result is as shown in the table.
The performance test results of table 1 pure cotton fabric after anti-crease finishing
As can be seen from table, anti-crease finishing liquid of the present invention has good anti-wrinkle effect---and compare undressed pure cotton fabric, its creasy recovery angle of pure cotton fabric through anti-crease finishing liquid process of the present invention all has obvious rising.Through the pure cotton fabric of anti-crease finishing liquid process of the present invention, there is the crease resistant finishing similar with resin finishing agent, but fabric strength retention rate be obviously better than resin finishing agent arrange after pure cotton fabric, and maintain the soft feel of pure cotton fabric itself.In addition, consider the factors such as crease resistant finishing, feel, ultimate strength reservation and Tear strength reservation, embodiment 3 is the preferred embodiment of anti-crease finishing liquid of the present invention.
Above embodiment is only the present invention's part embodiment, instead of whole embodiments.The explanation of above embodiment just understands method of the present invention and core concept thereof for helping; For one of ordinary skill in the art, according to thought of the present invention not making other embodiments all obtained under creative work prerequisite, all belong to the scope of protection of the invention.
