Abstract
The invention discloses a titanium-containing polyvinyl alcohol (PVA) cool towel and a manufacturing method of the titanium-containing PVA cool towel. The titanium-containing PVA cool towel is mainly prepared by adding titanium element, of which the weight is of 0.5-20% of the slurry, to the slurry in the preparation process, due to the mildew-proof effect, the titanium element can replace the traditional mildew inhibitors to overcome possible defects caused by allergies, eczema and odor and the like. The manufacturing method shortens the production cycle and increases the production efficiency through omission of the traditional mildew-proof process. Beside the mildew-proof effect, the titanium element also has beneficial physiological effects for human body.
Description
Technical field
The invention belongs to the cool towel field of PVA, being specifically related to a kind of without the need to adding mould inhibitor and without the need to the cool towel of PVA of mildew-resistant processing procedure and manufacture method thereof.
Background technology
The cool towel of PVA is by PVA(polyvinyl alcohol) conjunction system forms, PVA dissolving adds starch, and (starch plays gelatinization mainly for the production of in processing procedure, to improve the viscosity of raw material), water stir, add the obtained slurry of the stirrings such as appropriate acids, formaldehyde again and be incorporated to mould, add slurry again after adding mylar again, processing procedure is roughly as follows:
Slurrying material → formed product → cooling → drying → decomposition (cutting) → cleaning → mildew-resistant → packaging → product examine → shipment.
Mould inhibitor must be added in above-mentioned mildew-resistant processing procedure in the cool towel products of prior art PVA, ensure that the product of packaging shipment can not be mouldy.For adding the cool towel products having mould inhibitor, some consumers uses and has allergy, eczema phenomenon, and owing to adding mould inhibitor, has unpleasant taste when to open bag.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides the cool towel of a kind of titaniferous PVA and manufacture method thereof, the cool towel of titaniferous PVA of the present invention without the need to adding mould inhibitor and mildew-resistant processing procedure just can reach anti-mold effect, and also has for the useful physiological action of human body.
The present invention in order to the technical scheme solving its technical problem and adopt is:
The cool towel of a kind of titaniferous PVA, the raw material of the cool towel of described titaniferous PVA comprises the slurry containing PVA, and containing titanium elements in described slurry, described titanium elements accounts for 0.5% to 20% of slurry gross weight.
Preferably, described titanium elements accounts for 0.5% to 10% of slurry gross weight.
Preferably, described titanium elements exists with nano level metal titanium form.
In total weight percent, component and the proportioning of described slurry are as follows:
PVA：4%-10%；
Nano level metal titanium: 0.5% to 20%;
Water: 70%-90%
Paste agent: 2%-6%;
Formaldehyde: 2%-6%;
Acid: surplus.
Preferably, described paste agent is starch.
More preferably, described paste agent is wheat starch.
Preferably, the pH value of described acid is 1-2.
Preferably, described acid is at least one in hydrochloric acid and sulfuric acid.
Preferably, the raw material of the cool towel of described titaniferous PVA also comprises cloth.
The manufacture method of the cool towel of above-mentioned titaniferous PVA, is undertaken by following processing procedure: slurrying material → formed product → cool → dry → cut → clean → pack → product examine → shipment;
Wherein, slurrying material processing procedure is specific as follows: the component of slurry and proportioning are PVA:4%-10%; Nano level metal titanium: 0.5% to 20%; Water: 70%-90%; Paste agent: 2%-6%; Formaldehyde: 2%-6%; Acid: surplus; First PVA is added nano level metal titanium, water and paste agent to stir, then add acid and formaldehyde stirring, obtained slurry.
The invention has the beneficial effects as follows: the cool towel of titaniferous PVA of the present invention adds titanium elements in the preparation process of its slurry, because titanium elements has mildew-proof function, therefore traditional mould inhibitor can be substituted to overcome the defects such as allergy, eczema and the peculiar smell that may cause, and eliminate traditional mildew-resistant processing procedure, therefore shorten fabrication cycle, improve production efficiency, and titanium elements also has for the useful physiological action of human body except having mildew-proof function.
Embodiment
Embodiment: the formula of size of the cool towel of titaniferous PVA of the embodiment of the present invention 1 to 10 sees the following form 1:
Table 1(unit: weight percent)
Wherein, wheat starch is ideal paste agent, plays gelatinization mainly for the production of in processing procedure, to improve the viscosity of raw material.But also can adopt other starch, as W-Gum, yam starch etc., but from the outward appearance functional property of product, wheat starch is ideal; Same gelatinization can add water glass and substitute, though the shaping functional property of energy is not as good as wheat starch.
Wherein, acid is mainly sulfuric acid and/or hydrochloric acid, and pH value is comparatively reasonable at 1-2.
According to above-mentioned formula, the processing procedure of the slurry of the cool towel of titaniferous PVA of the present invention is as follows: first PVA is added nano level metal titanium, water and paste agent and stir, then adds acid and formaldehyde stirring, obtained slurry.
The manufacture method of the cool towel of titaniferous PVA of the present invention, is undertaken by following processing procedure: slurrying material → formed product → cool → dry → cut (decomposition) → cleaning → packaging → product examine → shipment.
Have above-mentioned manufacture method known, the present invention adds the nano level metal titanium with mildew-proof function in the process of slurrying material, and eliminate mould inhibitor required in traditional mildew-resistant processing procedure and mildew-resistant processing procedure, all the other processing procedures are all same as the prior art.
In the said products molding manufacture procedure, can add in the process of mould at slurry and add cloth, with make shaping after the cool towel of titaniferous PVA in the middle part of there is cloth, to improve the tearing toughness of cool towel.This cloth is preferably employing mylar.
Titanium is that one makes cell ionize by radiating consistent wavelength, regulates the element of body current.Thus useful physiological action is produced to human body.It by regulating electric current, can unbend sb.'s mind, improving motion function; By regulating amount of localized heat, make loosening all muscles; The Substrate and the tired factor produced by pain in blood flow is removed by stimulating blood flow help; To symptoms such as alleviation bursitis, sciatica, headache, sacroiliitis and premenstrual syndrome, there is obvious effect.Titanium is useful to human body, and quite safe, is very applicable to health.Ti product is owing to stabilizing body current, the tight state of loosen muscular, therefore, spirit can be loosened, muscle also can loosen gradually, and can motion function be improved, titanium elements thermal conduction is fast, makes the cool towel of the present invention can be more nice and cool relative to existing cool towel, a slight chill in the air is brought to the human consumers being in hot summer, safe and environmentally friendly.Cool towel of the present invention, due to not containing traditional mould inhibitor, so can not cause allergy, eczema, also can not have unpleasant taste to exist.
Above-described embodiment is only the illustrative principle of the invention and effect thereof, but not for limiting the present invention.The scope of the present invention, should listed by claims.
