摘要:
An antibacterial and antiviral degradable mask and a manufacturing method thereof are provided. From outside to inside, the mask sequentially comprises a surface layer (1), a core layer (2), and an inner layer (3) that contacts the face; the surface layer (1) is made of an antibacterial and antiviral cellulose spunlace non-woven fabric; the core layer (2) is made of a polypropylene melt-blown non-woven fabric; the inner layer (3) is made of a polypropylene spunbond non-woven fabric or a degradable natural cotton fabric. The mask can have both antibacterial and antiviral functions; moreover, the material is degradable, and thus, environmental pollution pressure caused by non-degradable petroleum-based fiber materials such as polypropylene can be effectively relieved.
摘要:
A flame-retardant ultraviolet-resistant aramid fiber, the preparation method therefor comprising the following steps: adding nanoparticles into a hydrogen peroxide solution, performing magnetic stirring for 0.5-1 h, adding a sulfuric acid solution, and further performing magnetic stirring for 0.5 h; performing filtering to obtain a filter cake, and washing the filter cake with water and drying same to obtain modified particles; modifying the modified particles with curcumin and dopamine to obtain organic substance-modified particles; and finally subjecting the organic substance-modified particles to a reaction with a silicon methoxylated aramid fiber, so as to obtain a surface-modified aramid fiber. The present invention has high ultraviolet absorption and extremely low catalytic activity, avoiding damage to a fiber structure by photocatalysis in a radiation process, and in particular improving flame retardancy of the aramid fiber.
摘要:
The present disclosure relates to a plastisol based composition for blocking dye migration from a dyed polyester blended cotton fabric or 100% polyester fabric into a print on the fabric, the print being done with a plastisol based color dye on the dyed fabric. The plastisol based composition of the present disclosure comprises an acrylic based resin devoid of vinyl chloride moiety, a plasticizer, an organic wetting agent, a formaldehyde free discharge agent and an extender. A process for printing fabrics using the plastisol based composition of the present disclosure is also disclosed.

摘要:
A process for the production of aminated cotton fibers by subjecting a raw cotton or cotton-polyester mixture to a modification with a saturated aliphatic compound of 3 to 15 carbon atoms which contains at least one primary, secondary, tertiary, or quaternary amino group and at least one hydrolyzable ester group, in which the saturated radical is straight chain, branched, or cyclic, and may be interrupted by one or more hetero groups and may be substituted by one or more hydroxyl groups. The modification occurs simultaneously with scouring, kiering, or dry mercerizing.
摘要:
The stability and softening performance of amidoamine fabric softeners, such as bis(hydrogenated tallow amidoethyl)-2-hydroxyethyl amine) is improved by protonating the amine with a neutralizing inorganic or organic acid and incorporating certain stabilizing emulsifiers, such as, N,N',N'-tris(2-hydroxyethyl)-N-tallow-1,3-diaminopropane, dimethylhydrogenated tallow amine, methyl dihydrogenated tallow amine, and oleic imidazoline). Mixtures of bis(hydrogenated tallow amidoethyl)-2-hydroxyethyl amine and bis(tallow amidoethyl)-2-hydroxyethyl amine also provide improved softening and form stable aqueous dispersions. The compositions may be highly concentrated for use at low levels or for further dilution prior to use.
摘要:
In a method for the flame-retardant treatment of fabrics by impregnation with a condensate of a tetrakis (hydroxyorgano) phosphonium salt and, e.g., urea, the addition of one or more protonated and neutralized amines to the impregnation solution increases the efficiency of fixation of the phosphonium salt within the fibers, improves its uniform distribution within the system and leads to improved flame-retardant and water-resistant properties.
摘要:
A fabric treatment composition contains at least a detergent active material, a fabric softening agent and 0.5 to 3% nonionic substituted cellulose ether derivative which has an HLB of 3.1 to 4.3 and a gel point of less than 58.degree. C., which improve softening performances on cotton while controlling deposition on synthetic fabrics. Ethyl, hydroxyethyl or methyl hydroxyethyl cellulose ethers are preferred. The detergent active material is anionic or a mixture thereof with other detergent active materials and may be present at 2 to 50% of the composition. The softening agent may be soap, a cationic material, a fatty amine and/or a clay with a soap/cationic mixture being preferred, and may be present at 0.5 to 50% of the composition.
摘要:
Adhesion between carbon fibers and thermoplastic matrix materials, used in carbon fiber composite materials, is promoted by the use of a bridging agent. The composite material includes: a plurality of carbon fibers; a thermoplastic matrix material intermingled among the plurality of carbon fibers; and a bridging agent adhering the plurality of carbon fibers to the thermoplastic matrix material. The bridging agent includes compounds having multifunctional groups that are capable of chemically bonding with a functional group of the carbon fiber and a functional group of the thermoplastic matrix material; but it excludes multifunctional amine compounds having metal-oxygen bonds.
