    专利说明:

    This invention relates to the production of a nonwoven fiber product, which consists, in whole or in part, of fibers having connecting properties.
    The purpose of the invention is to improve the quality of the material.
    A nonwoven fibrous product in which the fibrous material is wholly or partly composed of fibers that can form a compound with natural or man-made fibers of the same or a different type, is characterized in that said fibers that can form a compound are cellulosic carbamate fibers.
    Cellulose-based artificial fibers commonly used in the manufacture of non-woven fiber products, such as rayon fibers, can be fully or partially replaced with cellulosic carbamate fibers. By replacing the viscose fibers, in whole or in part, sufficiently durable products are obtained completely without the use of separate coupling agents. The ability to replace viscose fibers is in itself an advantage, since the process of making viscose fibers is very harmful for the environment. Polypropylene fibers are another type of fiber that is used that does not have good strength properties in the absence of a compound, either by bonding agents or by fusion.
    According to the invention, a portion of the fibers in the nonwoven fibrous webs may be lured, for example, 1-90% of cellulosic carbamate fibers, which can form compounds with other fibers in the fibrous product. In addition, the fibrous material in the fibrous product can be completely replaced by cellulosic carbamate fibers. In the production of a fibrous web, any technology that is used in the production of non-woven fabric can be used.

    wet cloths, wet process, water bonding process, etc. Canvases can also be formed by combing or other dry methods, and can also be joined by moistening. If necessary, other auxiliary substances (moisture-resistant resins, fillers, etc.) can be added to the web.
    The following fibers are used in the manufacture of non-woven fiber cloths: cellulose fibers - pine sulphate cellulose fibers, ground in a laboratory glender to a grinding degree of 20 ° SP (degree of grinding by the Schopper-Riegler instrument), the fibers remain in wet conditions between grinding and the formation of a fibrous sheet ; viscose fibers - 1.7 d Tech, length 6 mm (manufactured by Satery Co), having the following characteristics: minimum strength in air conditions 1.8, in wet conditions 0.9, maximum elongation in air conditions 25%, in wet conditions 32%, water retention 18-20 g NgO / g, product preservation 100-110%.
    Carbamate fibers are obtained from cellulosic carbamate prepared from bleached pulp and irradiated with an electron beam to obtain cellulose having a DP of 470. The pulp is fed with a readout solution containing 58% by weight of ammonia, 26% by weight of water and 16% by weight of urea . After impregnation, the ammonia is removed by evaporation, the fibers impregnated with urea are processed at 140 ° C for 3 hours. The cellulose carbamate fibers thus obtained have the following characteristics: Nitrogen content,% 2.6-2.9 DP280-290
    Clogging rate (-5 ° C) 220-345
    Viscosity (20 ° C)
    Pa3.6-4.4
    The extractable solution was prepared from carbamate fibers containing 7.3% by weight of cellulosic carbamate prepared in this way, 6% by weight of sodium hydroxide and 0.5% by weight of zinc oxide. The fibers are drawn from a solution into a solution of sulfuric acid / sodium sulfate, containing 79-80 g / l of sodium sulfate and 10.8 g / l of zinc. The fibers so stretched have the following characteristics after neutralization and washing:
    Nitrogen content,% 2.18
    d Tech1.5
    Strength, CN / d Tech2.25
    Elongation,% 8.6
    Example 1 A comparison is made for nonwoven fibrous products containing cellulosic and viscose fibers, respectively, cellulose.
    carbamate fibers made in the form of a sheet. The average weight per 1 m2 of sheets thus obtained is 60 g / m2. The strength characteristics of the obtained fibrous products are presented in table. one.
    The results presented in table. one,
     show that by using cellulosic carbamate fibers it is possible to obtain significantly better strength properties than using viscose fibers, therefore, viscose fibers are successfully replaced by cellulosic carbamate fibers.
    EXAMPLE 2 Nonwoven fibrous products made in the form of a sheet are compared, in which the fibers are mixtures of viscose and cellulose carbamate fibers. The average weight of 1 m sheets is 29.6 g / m2. The strength characteristics of fibrous products obtained by such
    are presented in table. 2,
    Tab. 2 shows that the higher the amount of viscose fibers replaced by cellulosic carbamate fibers, the better the strength characteristics obtained.
    EXAMPLE 3. Effects on moisture resistant properties of nonwoven sheets made of cellulosic carbamate fibers are studied.
    pitch. Sheets have an average weight per 1 m 33 g / m2. Moisture resistant Kuttepe 558 resin is added to cellulose fibers.
    in the amount of 1 wt.%, after which it is heated for 1 hour. The strength characteristics of the products thus obtained are presented in Table 3.
