Description
Technical Field
The invention belongs to the field of high-molecular adhesives, and particularly relates to a polyurethane adhesive for seamless down jackets and application thereof.
Background
With the rise of the light-weight down jackets, the down jackets are light, thin, soft, cold-proof, warm-keeping and foldable, and begin to enter the lives of people, so that the down jackets not only meet the warm-keeping requirements of people in winter, but also change the bloated and heavy images in winter, meet the requirements of beautiful people and people who are not frozen, and are popular with consumers. However, the down penetration phenomenon of the light-weight down jacket also brings inconvenience to the use of consumers.
In the prior art, down jackets are typically manufactured in 2 ways: one way is to sew the surface fabric layer and the lining layer of the down jacket together by a sewing machine or similar sewing equipment, and the ready-made garment manufactured by the sewing method usually runs down due to needle holes left at the sewing lines under the condition of long wearing time, thereby affecting the warm keeping and the beautiful effect of the down jacket. Patent No. CN106510034A discloses a preparation method of a down jacket: after the down-proof layer of the down jacket is sprayed with the strip hot melt adhesive in a spot coating mode (the hot melt adhesive is composed of 2 layers of structures of a water-based PU bottom paddle layer and a PA adhesive powder layer), the down-proof layer and a fabric layer are connected through hot pressing to form a down filling channel to replace a sewing process, although the problem of down running is solved, the method has the advantages of large equipment investment, complex operation, high precision requirement on the thickness and width of the sprayed adhesive layer and difficulty in production of a clothing factory. The other way is that a fabric factory bonds a fabric layer and a lining layer of the down jacket together when the fabric is manufactured by a thermosetting adhesive, then cuts the fabric according to the size and manufactures ready-made clothes, such as a down-spray glue cotton composite warm-keeping flocculus disclosed in the patent number CN2178726Y, and a thermosetting adhesive is adopted for connecting the surface layer and the middle layer of the down jacket described in the patent number CN 102514262A. Although the method solves the problems of down running and bonding of the conventional down jackets, when the method is used for manufacturing the down jackets by ready-made clothes factories, the cutting loss of the fabrics is large, the cost is high, the style and style of the product are single, and the method cannot adapt to the ever-changing market demands.

Referring to fig. 1 and 2, after the polyurethane adhesive of the present invention is applied to a composite structure adhesive film, the down jacket to which the composite structure adhesive film is applied comprises a lining layer 1, a facing layer 2 and a composite structure adhesive film 3, wherein the composite structure adhesive film 3 is composed of a cloth fabric 31 and polyurethane adhesives 32 compounded on the upper and lower surfaces of the cloth fabric 31; the upper surface and the lower surface of the composite structure adhesive film 3 are respectively adhered with the lining cloth layer 1 and the facing cloth layer 2, a plurality of down filling channels 4 are formed between the lining cloth layer 1 and the facing cloth layer 2, and down 5 is filled in the down filling channels 4. In order to form down filling channels 4 regularly arranged at intervals in the down jacket and ensure that down feather 5 can be always kept in the down filling channels 4 and prevent the down feather 5 from running out of the down filling channels 4, the composite structure adhesive film 3 is divided into a longitudinal adhesive film 3a and a transverse adhesive film 3 b; the longitudinal glue films 3a are longitudinally distributed at intervals and are adhered to the inner cloth layer 1 and the surface cloth layer 2 to form the down filling channel 4; the transverse adhesive film 3b is transversely arranged at the end part of the longitudinal adhesive film 3a and is adhered to the inner cloth layer 1 and the surface cloth layer 2 to seal the port of the down filling channel 4. The cloth fabric 31 is an X-shaped double-layer cloth fabric; in order to ensure that enough adhesive force is provided for firmly adhering the lining cloth layer 1 and the surface cloth layer 2, the width of the composite structure adhesive film 3 cannot be too small, when the composite structure adhesive film 3 is manufactured by adopting a common single-layer cloth fabric 31, the down jacket cannot be filled with the down feather 5 at the position adhered with the composite structure adhesive film 3, so that the heat preservation effect of the down jacket can be influenced; however, the X-type double-layer cloth fabric is adopted, so that the layers of the X-type double-layer cloth fabric are communicated with the down filling channels 4, down 5 is filled to the position where the composite structure adhesive film 3 is adhered, the heat preservation performance of the down jacket is improved, and the middle parts of the layers of the X-type double-layer cloth fabric are connected together, so that the condition that the two adjacent down filling channels 4 are communicated is avoided.
When the polyurethane adhesive is applied to a composite structure adhesive film, the composite structure adhesive film is soft in hand feeling, has good washing resistance and dry-cleaning resistance, and has high bonding strength to both a surface cloth layer and a lining cloth layer of a high-density low-surface-energy down jacket; therefore, the composite structure adhesive film is applied to the manufacture of the down jacket instead of the traditional thermosetting adhesive or the sewing process, the problem of down run of the traditional down jacket can be effectively solved, the operation is simple, convenient and environment-friendly, and the method can also be suitable for the production of the down jackets with various styles and styles.
