A method for shrink-proofing a cellulosic fiber textile that involves liquid ammonia treatment, hot water or alkali treatment under tension or under no tension, and with optional resin treatment.

Shrink-proof treatment of cellulosic fiber textile

A wood molding process which comprises treating woods with liquid ammonia, removing said liquid ammonia by evaporation, softening woods with heating and molding them into a desired shape, and treating the molded woods with hot water or steam.

Wood molding process

A method for finishing a cellulose fiber-containing textile fabric comprises treating a cellulose fiber-containing textile fabric with liquid ammonia, applying a resin finishing agent to said fabric, subjecting subsequently to either or both of a hot calendering treatment and a heat treatment, and finally treating the resultant fabric with hot water. The resultant fabric keeps its shape stability including a crease or shrink resistance when washed, without involving any problem on residual formaldehyde.

Method for processing cellulose fiber-containing textile fabrics

A system capable of measuring the heat and moisture transfer characteristics of thin materials such as clothing materials and the like simultaneously and accurately so as to obtain data for evaluating the suitableness of such material, for clothing. The sample 50 is set to partition the spaces 56 and 57, then the first and second types of air 1 and 2 which have been adjusted to the desired temperature and humidity flow into the temperature and humidity variation measurement section 53 in the desired amounts, respectively. The airs 1 and 2 are brought into contact with the temperature sensor 58 and the humidity sensor 59 at the inlet and outlet port of the section 53. An exchange of heat and moisture takes place between the air 1 and the air 2 through the sample 50. By measuring the temperature and humidity of the airs 1 and 2 at the inlet and outlet ports of the section 53, it is possible to understand the heat and moisture transfer characteristics of the sample 50. By varying the airs 1 and 2 to correspond to various temperature and humidity conditions at the outside and inside of a wearer's clothing, it is possible to measure the variations of the temperature and humidity of the air taking place through the sample 50 simultaneously and in a time-based manner.

Creases are formed in a cellulosic fiber textile by treating the fiber textile with liquid ammonia, creasing the fiber textile, and treating the fiber textile with hot water or alkaline solution substantially simultaneous with or subsequent to the creasing step. Fully durable creases are formed in the cellulosic fiber textile without detracting from strength.

Method for forming durable creases in cellulosic fiber textile

A process for resin finishing textile containing cellulosic fiber comprises the steps of using a resin finishing agent chiefly containing a cellulose-reactive N-methylol compound having two or more functional groups and a reaction catalyst, mainly reacting only one functional group of the cellulose-reactive N-methylol compound with cellulose, water washing, again imparting reaction catalyst, drying, garment making, and heat treating. The process eliminates the conventional postcuring method drawbacks of loss of color fastness and discoloration owing to dye decomposition and formaldehyde increase by unreacted resin and residual reaction catalyst during long storage before heat treatment, and simultaneously achieves high crease-resistant property, shrink resistance, good feeling, excellent pleating property, and anti-puckering property.

A twisting frame 1, and a method of twisting yarn 11 in which a twist is applied to the yarn by signals having a 1/f fluctuation to yield a yarn 11 in which the yarn count varies with a 1/f fluctuation. The first aspect is a twisting method that applies twist to a single yarn or a plural number of yarns, in which a twist is applied to the yarn or yarns by setting the twist count to correspond to the strengths of serial signals having a 1/f fluctuation.

Twisting method and twisting frame utilizing I/F fluctuations

A weaving method that imparts a 1/f fluctuation to the weave pattern. Adjacent and different numbered groups of different yarns, for example black yarn and white yarns, are alternately arranged in contiguous reed dents. The sequential number which is associated with each group manifests a series of numbers which effect the 1/f fluctuation. Following separation of the warp yarns into two sets by raising and lowering of healds to form a shed and passage of weft yarns therethrough, a woven fabric with a stripped 1/f fluctuation in the warp direction is created.

Method for weaving patterns having different yarn types alternately

In the blending and spinning processes, 1/f fluctuation signals are imparted to the feed slivers or rovings, wherein the blending ratio of the blended slivers, blended rovings, or blended yarn varies with a correlation, specifically a correlation with a 1/f fluctuation.

1 F blended yarn spinning method and blended yarn spinning frame

A weaving method that imparts a correlation of a 1/f fluctuation to the texture pattern of a woven fabric by passing warp yarns through a plural number of healds in a specific numerical sequence. The healds are then manipulated to separate the warp yarns into two sets to form a shed therebetween through which a weft yarn is inserted. For one texture pattern, warp yarns are threaded in groups in numbers corresponding to the values of a numerical sequence with a 1/f fluctuation through one set of healds. For another texture pattern, warp yarns are threaded in groups through another set of healds so as to alternate with the first groups, thereby weaving a plural number of texture patterns into the woven goods, with the overall texture design having a 1/f fluctuation.

A method for intermingling yarn, and an air intermingling machine 1 used therein, is provided that yields yarn with the comfortable feel of hand-spun yarn, on an industrial scale. In the air intermingling machine 1, intermingling is imparted to the yarn by signals having a 1/f fluctuation, wherein the degree of intermingling of the yarn vanes with a 1/f fluctuation provides a natural, comfortable feel.

A spinning method and a spinning frame are provided that yields spun yarn, with the comfortable feel of a hand-spun yarn, on an industrial scale. In spinning frame 1, rovings 11 are drafted with signals derived from a numerical sequence of having a 1/f fluctuation or signals derived from a melody or other sound having a 1/f fluctuation to yield a spun yarn 13 in which the diameter varies with said 1/f fluctuation, thus providing a natural, comfortable feel.

Spinning method and spinning frame

A weaving method for woven goods in which the warp yarns are disposed among reed dents of uniform spacing in a reed according to a sequence of numerical values having a 1/f fluctuation, thereby imparting a 1/f fluctuation to the arrangement of warp yarns.

Reeding method for 1/f fluctuation warp yarn distribution

A weaving method and reed where the method is practiced with the reed having spacings between dents of 1/f fluctuations resulting in a woven fabric which has a warp density of 1/f fluctuations. The spacings are established by winding yarn having a 1/f fluctuation around the dent support bars with the dents positioned between the coils of wrapped yarn.
