  • the flame retardant woven fabric prepared in Example 1 was immersed in this processing liquid, and treated in the same manner as in Example 1 to produce a woven fabric having an aldehyde deodorant adhered to the fiber surface.
  • This fabric was evaluated for its deodorant properties, and the results are shown in Table 1. The flammability of this fabric was acceptable.
  • Example 1 From the formulation of the working fluid of Example 1, a solution was prepared in which the titanium-silicon composite oxide and the aldehyde deodorant were removed, and the flame retardant fabric prepared in Example 1 was immersed in this working fluid. Processing was performed in the same manner as in Example 1. This fabric was evaluated for deodorizing properties, and the results are shown in Table 1. The flammability of this woven fabric was acceptable.
  • Example 5 The crimped tow prepared in Example 3 was cut to a single fiber length of 51 mm without being treated with a processing fluid, and then cut with a card machine to prepare a filling for filling in a wadding shape. . The deodorizing properties of the cotton were evaluated, and the results are shown in Table 1. '[Comparative Example 6]
  • Example 4 The artificial leather produced in Example 4 was evaluated for its deodorant properties without being treated with a working fluid, and the results are shown in Table 1. The water repellency of this artificial leather was first class.
  • Example 5 With respect to the force and the softness prepared in Example 5, the deodorizing properties without treatment with the working fluid were evaluated, and the results are shown in Table 1. Also, since no machining fluid treatment was applied to this tough surface, the antibacterial property of this surface was 0.3, which was a reject level.
  • the fibrous structures such as the flame retardant fabrics treated with the processing agents according to Examples 1 to 7 have excellent deodorization against formaldehyde and xylene which is a kind of VOC. It showed an effect, which persisted after washing.
  • the flame retardant fabric treated with the processing agent according to Example 1 had both deodorant performance and flame retardancy.
  • the processing agent treatment according to the present invention can be widely applied to fibrous structures composed of fibers, such as semi-finished products such as fabrics, nonwoven fabrics and cotton, and end products such as moquettes and carpets. it can. Therefore, the fiber structure (fabric, non-woven fabric, cotton, etc.) according to the present invention includes sofas, cushions, stuffed animals, cushions, comforters, mattresses, mats, plankets, shells, dakimakura, bed mats, etc. Bedding, curtains, rugs, carpets, mats, covers, goodwill, slippers. It is useful as a material used for interior materials such as sheet materials and vehicle interior materials such as car seats, and can impart excellent deodorizing performance and the like to these materials. In addition, a fibrous structure having flame retardancy and deodorant performance can be obtained by using it together with a flame retardant, which is particularly useful for interiors in public facilities.

Abstract

Cette invention se rapporte à une structure fibreuse ayant la capacité durable d'éliminer le formaldéhyde et les composés organiques volatils considérés comme les substances causant le syndrome des bâtiments malsains. Cette structure fibreuse se caractérise en ce qu'un oxyde composite contenant du titane et du silicium et un agent d'élimination des aldéhydes adhèrent à la surface des fibres par l'intermédiaire d'une résine de liaison. L'agent d'élimination des aldéhydes peut comprendre un composé hydrazide ou un composé hétérocyclique azoté.
