    A process for forming cloth-covered cushion articles. A mold is provided having the shape of the desired cushion article. In one form, a cloth covering is drawn into the mold. Foamable material is poured into the mold and cured to form the cushion article. The covered, cured article is removed from the mold and heated to at least the heat-fixable fiber set temperature of the cloth, as the cured foam acts as a male mold to hold the cloth in contour during heat setting. In another form, the foam is poured directly into the mold and cured. The cloth covering then is placed over the cured cushion and set.

    This invention relates to methods for producing soft padded cushion products including an outer fabric with a standing nap.
    The aim of the invention is to improve the quality of the pad.
    Figures 1-6 show the sequence of operations for forming a pillow with a fabric coating.
    The method of forming fabric coated pillow products involves the use of a mold having the configuration of the required pillow article into which a textile coating is inserted having threads subjected to thermal fixation. A foamable composition, e.g., polyurethane rubber, is then poured into the form and vulcanized to form a pillow body.
    The pillow is removed from the mold and heated to the temperature of the heat shrinkage of the yarns of the covering fabric, which is subjected to heat shrinkage to form a contour after the pillow is molded. The cushion foam cushion itself acts as a convex shape that provides the contour of the fabric coating during its heat shrinkage.
    It is advisable to provide heating of the mold to 130-150 ° F (54.44- 65.56 ° C) in order to facilitate the pricing process, which is significantly lower than the heat shrinkage temperature of the covering fabric. After the foam is cured in the mold, the coated cushion is placed in a kiln with a temperature of 360 F (182.22 ° C) for heat shrinking of the fabric. This results in significant savings as a result of eliminating reheating and cooling. When polyester fabric is used as a cushion cover, the molded cushion can be simply placed in a dry oven to heat the yarn into the contour on the cushion cushion.
    When using a nylon fabric as the outer layer of a fabric coating, the use of a high boiling point solution contributes to the shrinkage of the nylon fabric. For example, a dibasic acid ester solution can be applied to an undifferentiated

    nylon fabric for its heat shrinkage.
    The process according to the invention can be applied to form cloth-covered cushion products for any application, which include car seats, aircraft seats, seat cushions, chair cushions, headrest cushions, baby cots, etc.
    For the implementation of the method, a variety of woven materials, woven or knitted from artificial or natural yarns or fibers, which can be heat shrunk, i.e., can be used. This refers to the use of unfinished fabric, which means a fabric that has not been subjected to any circumferential treatment intended to impart fabric of unchanged size or shape, or shrinkage or fixation of yarn intersection points.
    The use of standing nap fabrics involves the use of fabrics that have a certain natural characteristic of the surface or a rise surface — velor, velvet, and a variety of fabric materials that have a certain pile that can be destroyed or have surface characteristics that are disturbed. or altered by heat or pressure. According to the invention, heat shrinkage is assumed for at least the upper fabric layer of a pillow covered with a fabric.
    contour formation after molding the pillow itself.
    The method involves the use of Form 1 (Fig. 1), having the configuration of a pillow product needed, for example, a seat cushion. A fabric covering 2 is provided for the pad. Some types of fabric typically include an outer fabric layer attached to an elastic composite layer. The fabric layer should engage with the inner surface of the mold 1. The composite layer typically includes a film layer and a foam layer sandwiched between the film layer and the fabric layer. The film layer allows the coating layer to be introduced under vacuum into the concave shape 1 (Fig. 2). After being introduced into form 1 tissue

    foam material (polyurethane rubber) 3, which is poured into the mold in a liquid state (Fig. 3). In the preferred embodiment, polyurethane of polyester type is applied, subjected to cold vulcanization, although any foam forming material that adheres to the film layer of the fabric coating can be used. Almost concave form 1 can be heated to 130 (54, to provide flexibility to the fabric cover.
    Then, the convex mold 4 is placed over the concave mold 1 (Fig. 4) and after about 15 minutes the foam 3 completely spreads in the volume of the mold. The unfinished product 5 can be removed from the concave shape 1, as shown in Fig. 5, which is placed in the furnace 6 and heated to the temperature of heat shrinkage of the threads of the fabric cover 2 (Fig. 6). The fabric coating 2 undergoes heat shrinkage by forming a contour after forming a foam cushion, which acts as a convex shape to maintain the fabric covering the contour n during heat shrinkage in the furnace 6. By the method of the reheating and cooling steps, the outer surface of the outer layer is eliminated. the surface is a form 1 which is sufficiently heated to shrink the fabric and change its natural characteristics.
    EXAMPLE 1 A formable fabric coating comprising a fabric layer of 14 ounces underdeveloped polyester wool material (296.9 g) was introduced into Form 1. Foam capable of forming foam. The material was molded into a mold in a liquid state and subjected to cold vulcanization. An incomplete pad product was placed in a furnace 6 and heated to ZbPT (182.22 ° C).
    The villous fabric was heat shrunk, while the cushion of cured foam acted as a convex shape to maintain the fabric covering in the loop during the heat shrinking of the fabric of which the lint remained unchanged and its natural surface characteristics were maintained.
    EXAMPLE 2. Forming a fabric including an outer layer of uncut nylon was placed in forms. Nylon fabric was Type 6.12 2 13 ounces fabric (340.2-268.55 g in a knitted material. Capable of Formation of foam material was poured into a mold in a liquid state and suspended from cold vulcanization 10. The incomplete pad product was sprayed with a cold solution of dibasic ester and placed in oven 6 with a temperature (iA8.88 ° C). Nylon fabric coating It was shrunk to the corresponding contour, while the vulcanizing bath cost 3 de It is used as a convex shape 4. The pad product was washed with a solvent to remove residual dibasic acid ester solution, and then dried to evaporate the solvent. The natural surface characteristics of 25 nylon fabric remained unchanged.
    Froze The nylon fabric that was molded was used in the process of Example 2, where instead of applying a cold solution of the two basic acid ester and heating the fabric covering the pillow, the dibasic ester solution in the furnace itself was heated at 300 ° F (148 , 88 ° C).
