摘要:
This method for manufacturing a shaped product is characterized in preparing a specific random mat including a thermoplastic resin and carbon fiber bundles having an average fiber length of 5-100 mm, impregnating a thermoplastic resin into the random mat, pressing the random mat in a metal mold in a range of 0.1-20 MPa, and then taking out the random mat from the metal mold.
摘要:
Bisperfluoroalkyl-substituted diols containing sulfide, sulfone or polysulfide linkages and a method for making them are described. These diols can react with isocyanates to form urethanes; diisocyanates to form polyurethanes; chloroformates to form carbonates; with carboxylic, sulfuric or phosphoric acids or derivatives to form carboxylate esters, sulfate esters, phosphate esters respectively. These diol compounds and their derivatives are useful for imparting oil and water repellency to substrates such as glass, wood, paper, leather, wool, cotton, polyester and other substrates.

The plurality of particles include: about 5% to about 99.9% by weight, optionally from 10% to about 99% by weight, optionally from about 30% by weight to about 95% by weight of a carrier system including a polyalkylenecarbonate compound. The composition further includes a fabric care benefit agent.
摘要:
A stab proof material in roll form comprising a matrix distributed over both the surfaces of a textile structure and forming a surface film totally interpenetrated in said textile structure. The production method comprises the steps of: unwinding an aramid fabric on conveyor means; distributing an amorphous thermoplastic matrix starting from a micrometric powder, over both surfaces of the aramid fabric as it is unwound; passing the material through a first hot section and then through a second relatively cold section; the first section applies a temperature and a pressure such as to form an amorphous thermoplastic film on the fabric; the second section facilitates detachment of the coated material from the conveyor means. The plant comprises a conveyor belt on which an aramid fabric is unwound; a powder scattering station adapted to distribute a micrometric powder on the aramid fabric as it is unwound on the conveyor belt; a system of double belts in contact through which the fabric is conveyed; the system of double belts in contact defines a first hot section and a second relatively cold section; the first section applies a temperature and a pressure functional to the formation of an amorphous thermoplastic film on the fabric; the second section facilitates detachment of the fabric.

The polycarbonate polyol (B) may contain a polycarbonate diol (B1). The blocked polyisocyanate (C) may contain at least one blocked polyisocyanate selected from the group consisting of an aliphatic polyisocyanate or derivatives thereof and an aromatic polyisocyanate and having a dissociation temperature of 120° C. to 180° C.
摘要:
A method and compositions for textile finishing utilizing non-formaldehyde-releasing, reverse water-soluble polymers as binder resins for textile finishes. Textiles treated by the disclosed method. The present invention is advantageous for health and safety reasons because it utilizes binder resins which do not release formaldehyde into the local environment.
摘要:
This invention relates to bonding coats and top coats made of aliphatic, segmented polycarbonate-polyurea elastomers for coating textile substrates. The coats are applied to the substrates from their solutions by the reverse roll coating process. The coating used has the advantage of providing resistance to hydrolysis, light fastness, unlimited pot life and can be prepared with inexpensive and physiologically harmless solvents. The synthetic leather has a high abrasion resistance, high folding strength, high flexibility in the cold and resistance to alcohol.
