DE TAIL E D DE S C RIPTION OF TH E INVE NTION
In general, the disclosed and claimed invention herein provides a non- woven apparel fabric consisting of a dyed or undyed non-woven fabric having a fibrous web needle-punched over a scrim and coated with polyurethane or acrylic. The disclosed invention also provides a method for manufacturing and processing to manufacture the non-woven apparel fabric which performs like a woven fabric and meet the apparel requirements. In general, the preferable process for manufacturing a non- woven apparel fabric comprises steps of providing a fibrous web of blended fibres, needle-punching said fibrous web of blended fibres over a scrim to form a needle-punched non-woven fabric, calendering the needle- punched non-woven fabric to form the needle-punched non-woven fabric having a smooth and lustrous surface, removing loosely bonded fibres and impurities from said needle-punched non-woven fabric by washing, dyeing the washed needle-punched non-woven fabric with a dye, coating said dyed fabric with acrylic— or polyurethane and other auxiliaries, and sanforizing to obtain the non-woven apparel fabric.
As shown in F igure 1 and 2, the first step (201 ,202) of manufacturing the non-woven apparel fabric is to form a fibrous web (20). The forming of the fibrous web (201 ,202) includes blending (201 ) the fibres in a blender (1 10), carding (202) the blended fibres (10) into parallel fibrous web (20) by a carding machine (120). The blending (201 ) can be done by sorting and feeding a desired proportion of the fibres in a blender. According to the present invention, the blend of fibers plays important role in the manufacturing of the non-woven apparel fabric. The blend of fibres comprises synthetic fibers, regenerated cellulosic fibres and/or natural fibers in a predefined proportion. For example, the blend comprises at least 20% synthetic fibers and at least 30% regenerated cellulosic fibers. Advantageously, the blend comprises the synthetic fibers in the range of 20% to 50% and the regenerated cellulosic fibers in the range of 30%- 80%. P referably, for example 40% polyester and 60% viscose. Blending of the fibers reduces the size of fibre tufts. The blend of fibres (10) from the blender (1 10) are transferred to the carding machine (120) where entangled fibres are individualized into a parallel fibrous web (20). According to the present invention, the fibrous web (20) from the carding machine (120) is then oriented in a cross direction in a cross lapper and scrim feeder (130) wherein a scrim (not shown) is fed parallel to the fibrous web (20) shown with a reference step 203. The fibrous web along with scrim (30) is then punched by a series of needles by a needle- punching machine (140) to form a needle-punched non-woven fabric (40) in the needle-punching process step (204). According to the present invention, the scrim used is 40 " 100 G S M by weight and the scrim is woven with warp and weft yarns obtained from either natural fibers or manmade fibers or in combination of both fibers. The design of non-woven apparel fabric is being controlled in the needle punching machine (140). The needle punching operation includes passing the fibres web with the scrim (30) through a pre-needle, drafting, and a finish needle loom. The needle-punched non-woven fabric (40) is then wound on a roll. Needle- punching (204) is a process of bonding non-woven fibrous web structures with the scrim by mechanically interlocking the fibres throughout the non- woven fibrous web within each other and the scrim. Barbed needles, mounted on a board, punches the fibrous web and then are withdrawn leaving the fibres entangled with each other and the scrim. Alternatively, the non-woven fabric with scrim can also be made of adhesive bonding, thermal bonding, through air-bond or hydro entanglement. The needle-punched non-woven fabric (40) is then passed through the calendering system (150). The process of calendering (205) is used to make the fabric smooth and more lustrous. The needle-punched non- woven fabric is pressed between a pair of rollers (not shown) at a pressure of 100N to 300N at a room temperature. The needle-punched non-woven fabric (40) runs through the rollers (not shown) that polish the surface and make the needle-punched non-woven fabric smooth and more lustrous.
The needle-punched non-woven fabric (40) subjected to calendering process (205) referred as a calendered needle-punched non-woven fabric (50) which is then followed by washing step (206) in a washing system (1 60) to remove loosely bonded fibres and also to remove impurities if any from the calendered needle-punched non-woven fabric (50). In the washing system (160), the needle-punched non-woven fabric (50) is washed with hot or cold water twice or thrice and then followed by drying process. The temperature of drying range may vary from 100eC to 1 50eC . The residual moisture in the dried washed needle-punched non-woven fabric (60) can be 4% to 8%.
As shown in F igures 1 and 2, the next step is dyeing (207) wherein the washed needle-punched non-woven fabric (60) is then dyed by using a dyeing system (170) with oxidative dyes or reactive dyes. The oxidative dyes can be an indigo dye, sulphur dye or vat dye. The dyed fabric (70) is then optionally subjected to a surface dyeing (209). The surface dyeing provides a differential look and appearance to the dyed non-woven fabric (80).
In the coating process (207), the dyed needle-punched non-woven fabric (70 or 80) is then coated by chemical treatments with acrylic or polyurethane by using a coating system (180) to obtain dyed non-woven apparel fabric (90). Optionally, as shown in the F igure 2, the washed needle-punched non-woven fabric (60) can be directly coated to obtain an undyed non-woven apparel fabric (90). Optionally, colour pigments may be added in the coating composition during coating process (207) to colour dyed or undyed washed non-woven fabric (60,70,80) to obtain a colour non-woven apparel fabric (90). The coating is applied by known paste or foam coating technique, wherein paste coating technique comprises 20% - 40 % polyurethane or acrylic, 4% - 6% coating auxiliaries (such as fixer and thickener) and remaining amount of water. The colour pigments may be added in the composition while preparing a coating recipe. The chemical treatment improves abrasion resistance and reduce piling tendency and improves the hand feel and rubbing fastness property. The coated fabric is then subjected to the sanforising step (210) for dimensional stability and improved hand feel of the non-woven apparel fabric (95). The dyed or undyed non-woven apparel fabric (90,95) can be converted into various type of apparels. The weight of the fabric depends upon the blend of the fibers and the type of the scrim used for making the non-woven apparel fabric. P referably, the non-woven apparel fabric has a weight about 120 to about 380 G S M. More preferable, weight of the non-woven fabric is about 140 to about 200 G S M.
The present invention provides a non-woven apparel fabric by modifying a non-woven fabric so that it can be used for apparel purpose. The present invention also provides a method for manufacturing the non-woven apparel fabric. The process requires substantially less time and minimum energy consumption for manufacturing the non-woven apparel fabric as compared to the presently available methods for manufacturing the apparel fabric. The process is substantially controllable and hence the non-woven apparel fabric can be engineered as required. The non-woven apparel fabric has no only aesthetic look, feel, drapability, tear and tensile strength like a woven or knitted apparel fabric but also is economical and price competitive as compared to the woven or knitted apparel fabric. It exhibits various performance due to the unique structure and incorporation of performance fibre. The following example further illustrate the present invention and is not to be construed as limiting the scope thereof.
