Description
Technical Field
The invention belongs to the field of textiles, and particularly relates to a textile additive for improving peel strength.
Background
The adhesive interlining is an extremely important auxiliary material in the textile technology, and directly influences the practical performance of textiles and clothes. The presence of the adhesive interlining greatly improves the processing efficiency of textile products, so that a mechanized assembly line can be realized. In the field of garment processing, the adhesive interlining can be used at a specific position to enhance the stiffness and play a role in local modeling and shaping. The clothes have the advantages of plumpness, lightness and stiffness after the adhesive interlining is used, and meet the requirements of modern people on the wearability. The advent of adhesive interlinings is an important hallmark of modern garment technology.
The textile fabric is bonded to the backing to form a fabric-hot melt adhesive-bonded liner combination, and the force required to separate this composite is referred to as the peel strength. The peeling strength directly affects the beauty, quality and service life of textile products, for example, shoes are frequently collided in daily wearing, and if the peeling strength of the hot melt adhesive between the vamp material and the sole is not high, the peeling and glue opening phenomena are easy to occur. In recent years, the popularity of outdoor sports and the demand in special areas, consumers have become more concerned about the functionality of garments. In order to endow a common fabric with a special function, the use of a functional auxiliary agent cannot be avoided in the fabric after-finishing process, and the peel strength of the treated fabric is often reduced compared with that of a bonding liner. Taking the current hot environment-friendly acrylate fluoride-free waterproof agent as an example, the treated fabric surface is enriched with a large number of acrylic acid chain segments, and the crystallization obtained by crosslinking in the shaping process covers the sites of the fabric surface which are bound with the hot melt adhesive to a great extent, and meanwhile, the methyl group modified by the waterproof agent shields the high surface energy of the fabric, so that the peeling strength of the fabric after waterproof finishing is reduced. Moisture-absorbing quick-drying finishing agents, flame retardants, ultraviolet-proof finishing agents and the like, and crosslinking agents added for increasing the washing fastness can further reduce the peel strength of the fabric.
The Chinese patent application with the application number of 201911302102.8 and the publication number of CN110922525A and the name of 'hydrophobic copolymer with high peel strength' discloses a hydrophobic copolymer with high peel strength and a preparation method thereof. The innovative product has excellent waterproof performance and peeling strength superior to that of a commercial waterproof agent product. However, when the fabric is used together with textile auxiliary agents such as moisture absorption quick-drying agents, other functions of the fabric to be treated can be influenced, so that the fabric cannot be used as an additive. Therefore, it is important to develop an additive which has universality and high efficiency and can improve the peeling strength.

the non-ionic emulsifier is selected from: any one or the mixture of nonylphenol polyoxyethylene ether, fatty alcohol polyoxyethylene ether and polyoxyethylene sorbitol monoglyceride;
the cationic emulsifier is selected from: any one or a mixture of cetyl trimethyl ammonium bromide, nonylphenol polyoxyethylene ether ammonium sulfate and octadecyl trimethyl ammonium bromide;
the emulsifier accounts for 3% -7% of the total mass of the monomer raw materials.
5. The method according to claim 3 or 4, characterized in that: the organic solvent is selected from: one or more of isopropanol, pentane, ethyl acetate, triethanolamine, methyl butanone, methyl isobutyl ketone, methyl acetone and ethylene glycol monobutyl ether;
the deionized water accounts for 45-55% of the total mass of the monomer raw material, the emulsifier, the organic solvent and the deionized water, and the organic solvent accounts for 10-17% of the total mass of the monomer raw material, the emulsifier and the organic solvent.
6. The method of claim 3, wherein: in step 2), the initiator is selected from: azo-type initiators or oxidation-reduction aqueous initiators;
the initiator accounts for 0.2-1% of the total mass of the monomer raw materials.
7. Use of the textile additive of claim 1 or 2 to increase the peel strength of a functional textile additive finished fabric.
8. A method for improving the peel strength of fabric finished by functional textile auxiliary comprises the following steps: compounding the textile additive of claim 1 or 2 with a functional textile auxiliary, and then carrying out after-treatment on the fabric.
9. The method of claim 8, wherein: the functional textile auxiliary agent is a waterproof agent, a water-repellent oil-repellent agent or a moisture-absorbing quick-drying finishing agent.
10. The method according to claim 8 or 9, characterized in that: the textile additive accounts for 5-15% of the mass of the functional textile auxiliary.
